Anaerobic+bacteria species are also isolated from patients with dental infections, anaerobic pleuropulmonary infections, from skin and soft-tissue abscesses in intravenous drug abusers ( A. If the diagnosis of actinomycosis can be obtained preoperatively, antibiotic treatment may lead to complete resolution ( 24, 34, 60, 86). This species has been reported in a case of renal actinomycosis mimicking renal carcinoma ( 24). israelii may cause localized tumor-like infections. Pelvic actinomycosis associated with intrauterine device might mimic pelvic malignancy and A. Recently a case was reported where retained intrauterine fetal bone was detected and the agent of infection was identified as Anaerobic+bacteria israelii ( 86). Although most cases of pelvic actinomycosis are associated with long term use of an intra-uterine device, also other foreign bodies may cause similar pathogenesis. Anaerobic+bacteria species are relatively often recovered from female genital tract infections, especially in women using intrauterine contraceptive device. The infections in which this group of microorganisms most often has been recovered are skin and soft tissue infections, chronic otitis media and sinusitis, aspiration pneumonia, intra-abdominal infections, gynecological infections, and dental infections ( 13, 43).Īctinomycosis is an uncommon bacterial infection that has a characteristic chronic indolent course. They are often mixed with other anaerobic or aerobic bacteria. These opportunistic pathogens are seldom recovered as single isolates ( 13). They are generally considered to be of relatively low virulence and are especially prevalent in infections associated with predisposing or underlying conditions such as previous surgery, malignancy, immunodeficiency, diabetes and presence of foreign bodies. The anaerobic Gram-positive cocci and anaerobic Gram-positive non-sporeforming rods such as Anaerobic+bacteria, Bifidobacterium, Eubacterium, Lactobacillus and Propionibacterium species are, for the most part, components of the normal flora of the mucosal surfaces and, to a lesser extent, the skin.
