  1. Actinomycetes are also the source of numerous antibiotics. Most of actinomycetal antibiotics used to combat plant diseases belong to the genus Streptomyces and are used as direct pesticides. Other genera also demonstrate promising biocontrol properties. Among the antibiotics obtained from Actinomycetes which are used in human and veterinary medicine are amphotericin, cyclohexymide, nystatin, and streptomycin.1

Antibiotics are the primary treatment for actinomycosis. High doses of penicillin are usually necessary to cure the infection. If you’re allergic to penicillin, your doctor can give you other antibiotics, such as: Actinomyces definition, any of several saprophytic, filamentous, anaerobic bacteria of the genus Actinomyces, certain species of which are pathogenic for humans and animals Basic tests reflect the nonspecific inflammatory nature of the illness. There is usually a mild leukocytosis, predominantly polymorphonuclear, and, depending on the duration of the illness, a normochromic anaemia. The erythrocyte sedimentation rate and the C‐reactive protein may be moderately raised as with any chronic disease and these probably do not confer any diagnostic advantage.In rare cases, actinomycosis in the nasal sinuses can reach the brain. This may lead to another serious type of infection called meningitis.Инфильтрат в параректальной клетчатке способен стриктурировать прямую кишку, вызывая запоры. В период прогрессирования воспаление "легко" распространяется из параректальных зон на прямую кишку, ягодичные, паховые, промежностные области и верхнюю треть бёдер[1][12][20].

Abdominal actinomycosis occurs in the abdomen, but it can affect any part of the digestive system, from the food pipe to the anus.Actinomyces belong to the normal indigenous microflora, so they are considered as facultative pathogens. Actinomycosis is usually associated with the breakdown of normal physical barriers, such as disruption of mucosal membranes [140]. Little more is known about the molecular mechanisms by which the Actinomyces cause actinomycosis. Most infections with Actnomyces spp. are polymicrobial and members of the Streptococcus genus are the most commonly associated organisms. They act synergistically by inhibiting host defence mechanisms and reducing oxygen tension in the affected tissue, which enhances growth of Actinomyces spp. [146].При абломинальном актиномикозе ирригоскопия выявляет характерные соединительнотканные перетяжки, отходящие от инфильтрата в брюшной полости к стенке кишки, в виде, так называемых, спикул и зубчатости, которые иногда называют "симптомом пилы".Симптомы. В области внедрения актиномицет в гениталиях медленно развивается актиномикотическая гранулёма. Вначале процесс протекает бессимптомно или с минимальными жалобами. Постепенно формируется инфильтрат повышенной плотности, который можно определить на УЗИ или при прощупывании со стороны влагалища или передней брюшной стенки в надлобковой и подвздошных областях. Позже в стадии абсцедирования появляется тянущая или пульсирующая ощутимая боль, которая может иррадиировать из малого таза на прямую кишку, бедро, поясничную и надлобковую области. Вскрываются свищи во влагалище, прямую кишку, иногда в мочевой пузырь.

But a family of bacteria known as Actinomycetaceae causes it. The bacteria in this family include Your doctor uses a microscope to check the sample for Actinomyces bacteria Actinomycetes reproduce either by spore formation or hyphae fragmentation. The hyphae of Actinomycetes are much smaller than fungal hyphae, being one-fifth to one-half of fungal hyphae which often bear long chains of spores. These chains can be straight, wavy, hooked, or in tight spirals. The non-sporulating Actinomycetes in the genera Rhodococcus, Nocardia, Gordonia, Mycobacterium, and Dietzia are free-living aerobic bacteria that have broad metabolic capabilities. They can degrade to some extent even the most persistant man-made chemical compounds such as organochlorines, carbamates, and organophosphates.4 Most Actinomycetes are not motile. Actinomycosis is usually caused by the bacterium Actinomyces israelii. This bacterium is normally present in the mouth but can cause disease if it enters tissues following an injury

The presentation of pulmonary actinomycosis has also changed. It now appears less aggressive in nature compared with the pre-antibiotic era 12. These changes in both the disease's presentation and its incidence may be the result of improvements in oral hygiene, in the ready availability of antibiotics and in the early initiation of treatment when pulmonary infection is suspected. Actinomyces spp. are sensitive to several antibiotics in common use 27. In the developing world, where healthcare resources are limited, it is possible that the incidence of the disease may be higher, but accurate data are lacking. Even in the developed world, the disease's incidence may be an underestimation; the diagnosis is quite difficult to make in the first place and it is possible some early cases are being inadvertently treated and cured when antibiotics are given for other reasons 28. Somewhat surprisingly, socioeconomical class per se does not appear to correlate with disease incidence in the developed world 29.

Actinomyces stain in tissue with Gomori methenamine silver and the Brown and Brenn modification of the Gram stain 8. Most of the literature classifies the tissue response as granulomatous or “granulomatoid-like”, although giant cells and granulomata are rarely seen 39. Sulphur granules are the pathological hallmark of the disease. These are round or oval basophilic masses with a radiating arrangement of eosinophilic clubs on the surface; they sometimes can be seen even with a magnifying glass. The name “sulphur granule” has its origin in the small nodules resembling elemental sulphur that were commonly used in pharmaceuticals in the 19th century 4. Although they are usually highly suggestive of actinomycosis, they are not diagnostic on their own; they are also seen in nocardiosis, chromomycosis, eumycetoma and botryomycosis, albeit very rarely 39.Актиномициты из зоны внутренних гениталий могут "безудержно" распространяться на переднюю брюшную стенку, в область больших половых губ, промежность, поясницу, паранефральную клетчатку, под ягодичные мышцы и на внутреннюю поверхность бёдер[4][14].Respiratory physicians should be aware of this important differential when investigating patients for persistent pulmonary shadowing.

  2. A number of Actinomycetes form close association with plants and act as growth-promoting and biocontrol agents. Some Actinomycetes form lichen-like associations with green algae called actinolichens. Though most actinomycetes are saprophytes (feeding on decaying organic material), some cause diseases in plants (e.g. potato scab, gall, and wilt) and animals. Most members of Actinomycetes are aerobic, but a few can grow under anaerobic conditions.7

Actinomycosis is a chronic, slow-growing, inflammatory mass, most frequently affecting the lungs, cervicofacial region, abdomen, and pelvis (in association with intrauterine devices). Cerebral involvement is rare and manifested as an abscess (solitary or multiple) and, less commonly, meningitis. CNS Actinomyces may be difficult to recover on culture. The etiology of CNS disease may be inferred if Actinomyces spp. are isolated at another site. Standard recommended treatment for CNS disease is penicillin for at least 6 months. Recently, successful shorter courses of treatment with drugs other than penicillin for CNS disease have been reported. Surgical drainage may also be needed.Эндогенные (внутренние) очаги инфекции — кариозные зубы, миндалины, аппендикс, каловые камни, внутриматочные спирали и другое.

Actinomycosis: Causes, Symptoms, and Diagnosi

Pulmonary actinomycosis is a difficult condition to diagnose. Even among experienced physicians, sometimes despite pointers to the disease, delayed diagnosis or misdiagnosis as tuberculosis, lung abscess or lung cancer is common 12. The epidemiological, clinical, diagnostic and therapeutic characteristics of the disease are reviewed here. An increased awareness of the infection may expedite diagnosis and prevent undesirable complications, including unwarranted surgery, in patients under investigation for persistent pulmonary shadowing.Противовоспалительная антимикробная терапия проводится с учётом чувствительности сопутствующей микрофлоры к препаратам. Actinomyces spp. are filamentous, branching, gram-positive, pleomorphic, non–spore-forming, catalase-negative, anaerobic or microaerophilic/capnophilic bacilli. Although many species have been associated with disease in humans, actinomycetes usually are soil dwelling organisms.16 Actinomyces cannot be distinguished from Nocardia on Gram stain.17 However, Nocardia spp. grow aerobically and stain with acid-fast technique, and Actinomyces spp. do neither. With the use of 16S (small subunit) ribosomal RNA (16S rRNA) sequencing, at least 21 species of Actinomyces have been identified in humans. A. israelii is the predominant disease-causing species (median, 73% of cases), although other Actinomyces spp., including A. naeslundii (the second most frequent Actinomyces sp.)16 A. meyeri, A. odontolyticus, A. gerencseriae, and A. viscosus, as well as Propionibacterium propionicum, also have been implicated.18,19 Many different Actinomyces spp. are associated increasingly with infections at many body sites, and currently, 25 Actinomyces spp. have been described from human material.20 Most actinomycotic infections are polymicrobial, involving other aerobic and anaerobic bacteria. Coisolates depend on the source or site of infection and include Aggregatibacter (formerly Actinobacillus) actinomycetemcomitans, Eikenella corrodens, Bacteroides, Fusobacterium, Capnocytophaga, aerobic and anaerobic streptococci, Staphylococcus, and Enterobacteriaceae.

Actinomycosis starts in the soft tissues of the body, but it can infect any surrounding bone if it’s left untreated. Surgery may be necessary to remove any infected bone. If the infection resides in the nasal sinuses, surgery may be required to remove damaged bone and tissue.

Tropheryma whippelii, closely related to the actinomycetes, causes Whipple’s disease—a rare chronic multisystemic disease affecting people with defective T-lymphocyte.34 T. whippelii are ubiquitous organisms found in the saliva of people with Whipple’s disease,24 and often in those without.25,35 This bacteria hydrolyzes esculin, produces acid from xylose and is urease and catalase negative. Actinomyces israelii (bacteria). Known as: Corynebacterium israeli.. Most people have Actinomyces bacteria in the lining of the mouth, throat, digestive tract, and urinary tract, and it is present in the female genital tract Actinomycosis has been reported around the world. Although there is little accurate prevalence data in the literature, the incidence of all forms of actinomycosis appears to have declined markedly in the last three to four decades 12. The pulmonary form of actinomycosis constitutes ∼15% of the total burden of disease, although estimates of up to 50% have been reported 12–15. It is now a rare infection, particularly in the developed world. In the current authors' 1,100-bed teaching hospital (Nottingham City Hospital, Nottingham, UK), serving a large metropolitan area in the UK and acting as a regional centre for thoracic surgery, pulmonary actinomycosis was diagnosed histologically in only four cases over a 15-yr period (I. Soomro, Dept of Histopathology, City Hospital, Nottingham, UK, personal communication). Table 2⇓ summarises all series of pulmonary actinomycosis with more than five cases reported in the adult English language literature in the last two decades.Although there is considerable data on the use of MRI in other forms of actinomycosis, such as in the central nervous system, there is little data for its use in the thoracic form 50. Part of the reason may be the attendant problems associated with imaging the chest using MRI.

If your mouth tissue is infected, it can cause what’s commonly known as “lumpy jaw.” A hard lump can be felt in the jaw. The lump itself isn’t typically painful. However, it can result in a painful skin abscess that first appears as a reddish bruise at the site. Actinomycosis can also cause muscle spasms in the jaw or a “locked jaw.” If this happens, the mouth cannot open in a normal way.The bacteria live harmlessly in the body, but they become dangerous if they spread out of their usual environment.An early, accurate diagnosis will prevent the considerable psychological and physical morbidity, including unwarranted surgery, associated with delayed diagnosis.Radiological pulmonary actinomycosis can resemble a spectrum of lung pathologies ranging from benign infection to metastatic tumour. The main problem is distinguishing the disease from a neoplasm 46. Although, in experienced hands, some forms of imaging may show features more suggestive of actinomycosis, or at least an inflammatory process, than a neoplasm 47, imaging modalities on their own are not diagnostic. Definitive diagnosis is still based on histological or microbiological conformation. Imaging is useful in evaluating the exact location and extent of disease to help direct accurate biopsy and to monitor response to treatment. Irrespective of the imaging modality, a few general principles apply. First, the radiological findings depend on the duration of the infection; in the early stages of the infection, the findings are usually indistinguishable from those of any other pneumonic process. Secondly, the disease usually shows a peripheral and lower lobe predominance, probably reflecting the role of aspiration in its pathogenesis 19. Finally, the disease usually shows some diminution in size within 4 weeks of starting treatment 40. Actinomyces spp. are higher prokaryotic bacteria belonging to the family Actinomyceataceae

Из-за несвоевременной диагностики и запоздалого лечения актиномикоз приобретает хроническое течение, рецидивирует, длится годами и отрицательно влияет на качество жизни пациента.Even with extensive pulmonary disease, medical cure should still be attempted. Nevertheless, surgery remains an important therapeutic adjunct. It is particularly useful if there are complications, such as well-defined abscesses and empyemas, or where discharging fistulas and sinuses may need to be opened up 68, or, in very rare instances, to control life threatening haemoptysis that can occur with the infection 69, 70. When surgery has been the initial treatment, even if histology suggests complete resection, it still needs to be followed by prolonged antibiotic therapy, as surgery alone is usually not curative 71, 72. Inadequate antibiotic therapy postoperatively may result in complications such as broncho-pleural fistulas and empyema.

As the condition progresses, the deep tissue can become inflamed and pus-filled. It can result in abscesses, tissue death, cavities, and masses of fibrous tissue in the body.Actinomycetes normally reside in human mouth, throat, gastrointestinal tract, and urogenital tract without producing disease. Since the organisms cannot invade a human or animal body, they must be introduced by a deep puncture wound or trauma such as dental extraction or jaw trauma, aspiration of dental debris, surgery (removal of the appendix), or prolonged use of intrauterine devices. Actinomycetes require dead or devitalized tissue to facilitate their invasion and proliferation into deeper tissues. Establishment of human infection by Actinomycetes always requires the presence of companion bacteria. These companion bacteria help in initiation of infection by producing a toxin or an enzyme or by inhibiting host immunity. Once the infection by Actinomycetes is established, the immune system of the infected human host stimulates an intense inflammation. Bacteria from the infected site may disseminate to distant organs of the body.2 The Actinomycetes are particularly common type of bacteria found on moldy hay. Farmers may be routinely exposed to very high concentrations of Actinomyces and may inhale as many as 750,000 spores per minute. Frequent exposure to Actinomyces is the cause of Farmers Lung respiratory problems.5

The rationale for the use of penicillin in actinomycosis is based more on extensive successful clinical experience over the last 50 yrs than on randomised control trials 12. The main principle of treatment is the use of high-dose intravenous penicillin for a long duration of treatment. Although treatment has to be tailored to the individual, generally 18–24 million units of penicillin per day are given for 2–6 weeks followed by oral therapy with penicillin V (or amoxicillin) for 6–12 months. In general, the thoracic form appears to require longer treatment courses compared to the other commoner forms 40. Tetracyclines are the alternative especially for penicillin-allergic patients. In pregnant, penicillin-sensitive patients, erythromycin is a safe alternative. Other alternatives, which are probably effective, but for which there is less extensive clinical experience, are shown in table 4⇓. Чернеховская Н.Е., Бурова С.А., Поваляев А.В.

A vital step in the development of actinomycosis is the disruption of the mucosal barrier, allowing the organisms to invade. For cervicofacial and abdominal actinomycosis, such a break may result from dental sepsis, appendicitis, diverticulitis, trauma or surgery 4. For pelvic disease it may result from the use of intra-uterine or intravaginal devices 5. Pulmonary actinomycosis probably results from aspiration of oropharyngeal or gastrointestinal secretions into the respiratory tract 2. Poor oral hygiene and associated dental disease may increase the risk 12. Support for aspiration as a risk factor comes from reports of a higher prevalence of alcoholism in patients with the pulmonary form of the disease and from the basilar predominance of the disease radiologically 10. In the pre-antibiotic era, transdiaphragmatic spread of infection from the abdomen was an important route in thoracic actinomycosis, but this is probably no longer so 2, 12. Infection as a result of distant haematogenous seeding, lymphatic spread or spread from the neck through the mediastinum is also now very rare 10. The haematogenous route of dissemination may be a more important source in paediatric thoracic actinomycosis, where the disease has been noted to occur in apparently healthy children with “good” dental health 14, 15.

В этих случаях не исключено развитие вторичного актиномикоза по типу остеомиелита. Он отличается краевой узурацией (выемкой) коркового вещества кости, оссифицирующим периоститом, секвестрацией (отторжением отмирающей кости) и мелкими очагами остеолиза — "пробойниковыми" отверстиями в костной ткани, которые являются отличительной чертой актиномикоза. Эти изменения характерны и для других костных локализаций заболевания[1][2].Actinomyces spp. are gram-positive, obligate anaerobes known to reside in the mouth and intestinal tract. They are morphologically similar to fungus in that they form filamentous branches. Pathology due to proliferation of organisms usually occurs following injury or trauma to tissue, resulting in actinomycosis (abscess formation and swelling at the site of infection). Microscopic examination of pus reveals exudates with granular texture caused by sulfur granules, resulting from the bacterium and its waste. A. israelii is most commonly associated with actinomycosis; however, other Actinomyces bacteria are capable of causing disease. Actinomycosis can be treated with penicillin. Actinomyces israelii es la especie de bacteria más importante del Género Actinomyces. Fue descrita por Kruse en 1896 y anteriormente se le conoció con el nombre Streptothrix.. Background.

Authors of a study published in 2014 suggest the following ways of reducing the risk of developing actinomycosis:In 1957, Bates and Cruickshank 31 described a fairly dramatic presentation of pulmonary actinomycosis with prominent chest pain and cutaneous fistulas discharging sulphur granules. This mode of presentation has changed with time in line with the decrease in the disease's prevalence 40, 41. The commonest presentation is probably now as a shadow on a chest radiograph, similar to that caused by bronchial carcinoma. In a previous review of thoracic actinomycosis in five health regions in the UK, the current authors found the three commonest complaints to be cough, sputum and chest pain (table 3⇓). While chest pain was a prominent symptom and may act as a pointer to actinomycosis, the disease's symptoms are still quite nonspecific and similar to those of other chronic suppurative chest diseases and malignancy. In a patient known to have pulmonary actinomycocis, marked weight loss, malaise and high fever may be more suggestive of disseminated disease 10, 11. Physical signs are equally nonspecific, except in advanced, untreated disease, when sinuses and fistulae may then give the diagnosis away. The findings are occasionally those of the associated complications, such as pleural effusion or empyema.

Actinomycotic infections may mimic more common oral diseases or present in a similar way to malignant disease. Rarely seen in day-to-day dental practice, actinomycosis of the oral cavity is a highly significant condition due to its aggressive and locally destructive nature. Actinomyces israelii may cause orofacial actinomycosis mimicking the clinical appearance of a tumor of the upper gingiva. The bacterial colonies lead to formation of bleeding granuloma lesions which may contain pus.10 A. israelii aspirated from the oropharynx, may arrive into the lungs, and using the haematological way can spread into the heart, causing sudden death.Actinomyces is a genus of the Actinobacteria class, ubiquitous Gram-positive bacteria which include A. odontolyticus, A. oricola, A. radicidentis, A.c radingae, and A. slackii. Some, such as A. naeslundii, A. viscosus, and A. odontolyticus may be involved in the etiopathogenesis of dental caries and periodontal disease. Actinomyces spp. now classified as Aggregatibacter actinomycetemcomitans (AA) are periodontal pathogens, which may be transmitted in saliva. A. actinomycetemcomitans is also a part of the Haemophilus aphrophilus, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae group of bacteria (HACEK) that cause some infective endocarditis. A. actinomycetemcomitans may also play a role in acute coronary syndromes,29 and patients with diabetic kidney disease have more A. actinomycetemcomitans in dental plaque (and saliva) and a raised incidence of cerebral infarction.30 Actinomyces is a genus of the Actinobacteria class of bacteria. Actinomyces species may form endospores, and, while individual bacteria are rod-shaped, Actinomyces..

Belly fat is the most harmful fat in your body, linked to many diseases. Here are 6 simple ways to lose belly fat that are supported by science. Bacillus* Listeria Nocardia*. Actinomyces Clostridium. Miscellaneous / Poorly Staining Species. Intracellular Bacteria Chlamydia Rickettsia Borellia In some cases, a surgeon may drain an abscess or remove an infected part. After this, the person may need a 3-month course of antibiotics to resolve the problem.

Actinomyces species are found in humans as components of the normal microbiota throughout the upper respiratory tract, as well as the gastrointestinal and female genital tracts. They are particularly common in the oral cavity (Sarkonen et al., 2001) where they are prominent components of dental plaque and calculus (Kianoush et al., 2014). Many species have been isolated from animals in which they can cause disease, such as lumpy jaw of cattle. While most infections are due to one's own microbiota, infections due to exogenous sources, such as human or animal bites, can occur. Actinomyces have not been isolated from the environment (Smego and Foglia, 1998).Actinomyces are fastidious bacteria that are difficult to culture. Bacterial confirmation of a clinico-pathological diagnosis is usually obtained in <50% of cases due to inadequate culturing technique, previous antibiotic therapy and bacterial overgrowth, even when the clinical suspicion is high 2. Actinomyces are sensitive to most of the antibiotics used in everyday practice; even a single dose of an antibiotic before culture may inhibit the organism's growth 27. Correct techniques for collecting and delivering tissue specimens for anaerobic culture are vital, as is communication between the clinician and the microbiologist. Culture requires brain/heart-enriched agar and the organisms grow best at a temperature of 37°C in an atmosphere of 6–10% ambient carbon dioxide. A. viscosus is unique because it grows under microaerophilic or aerobic conditions. A few strains of A. israelii are also microaeropholic. Characteristically, colonies of Actinomyces appear as “molar-tooth” or “bread-crumb” colonies in broth media after 3–7 days of incubation. For adequate growth, however, cultures should be observed for up to 21 days. Differentiation of the species is difficult, requiring assessment of several metabolic capabilities. Fluoroscein-conjugated antibody typing is now available for species differentiation in some centres 28.Актиномикозу молочной железы обычно предшествуют травмы, мастопатия, гнойный мастит и переохлаждение. Клинически характерно отсутствие сильных болей, несмотря на наличие "впечатляющих" плотных инфильтратов и абсцедирования. Постепенно изменяется цвет кожи над инфильтратом от красного до багрово-синюшного, появляется один или несколько свищей, гной с включениями в виде мелких зёрен (друз) и рубцовые изменения в ткани молочной железы.Actinomyces species are found in humans as normal flora throughout the upper respiratory, gastrointestinal, and female genital tracts. They are particularly common in the oral cavity where nine species are found Sarkonen et al (2001), and they are prominent components of dental plaque and calculus Shuster (2002). Several species have been isolated from animals and can cause disease, such as lumpy jaw of cattle. While most infections are due to ones own normal flora, infections due to exogenous sources, such as human or animal bites, can occur. Actinomyces have not been isolated from the environment Smego and Foglia (1998).Отличительные симптомы абдоминального актиномикоза отсутствуют. Но его можно заподозрить, если обнаруженное уплотнение в брюшной полости долгое время остаётся малоболезненным, инфильтрат имеет доскообразную плотность, при этом общее состояние пациента страдает мало, вес не снижается. Только в стадии абсцедирования болезнь приобретает острое течение, поднимается температура, усиливается боль, изменяются показатели крови. Устья свищей выступают на поверхности и гранулируют.

Общие профилактические меры для всех локализаций актиномикоза заключаются в соблюдении здорового образа жизни и правил гигиены, поддержании уровня иммунитета, своевременного лечения хронических заболеваний, особенно одонтогенных, избегания травматизма, алкоголизма. Actinomyces); - стрептомицеты (лат. Streptomyces); - мадуромицеты (лат. Actinomyces), эти виды фитопатогены и нападают на клубни картофеля и.. Actinomycosis can take a variety of forms. It can also resemble other infections, and even neoplasms, or tumors.Актиномицеты, вызывающие заболевание, содержатся в почве. Их можно обнаружить даже в горячих минеральных источниках, на каменистых породах и в песках Сахары. Они не способны проникнуть в организм через здоровую кожу и слизистые оболочки, поэтому попадают только при повреждении барьерных покровов на фоне сниженного иммунитета.
