Peptococcus

Peptostreptococcus is a genus G+ (Gram stain) non-sporulating anaerobic cocci. They occur as a physiological microflora of the skin, mucous membranes of the gastrointestinal tract, oral cavity and genitals. On their own, they usually do not cause diseases, on the contrary, they typically cause them mixed polymicrobial infection of endogenous origin with the formation of abscesses,  peritonitis and  wound infections. It is necessary for the development of the disease reduced redox potential tissue hypoxia due to injury, vascular supply disorder, tumor, and the like.

Pathogenicity
Bacteria genus Peptostreptococcus are oral pathogens periodontitis and peritonsial abscesses. When aspirated into the airways, they can also cause sinusitis, otitis, pneumonia (up to necrotizing) and  pulmonary abscess. They also cause labor endometritis and other inflammatory processes in the small pelvis, often followed by  bacteremia and sepsis.

Combined with Streptococcus pyogenes and Staphylococcus aureus (STAU) evoke anaerobic streptococcal myonecrosis clinically similar Clostridium myonecrosis, but with a slower course. Muscle tissue is [edematous] with purulent, foul-smelling effusion and gas production. The highest pathogenicity showPeptostreptococcus magnus, Peptostreptococcus anaerobius and Peptostreptococcus asaccharolytius. They are also the most common members of this genus isolated from clinical material.

Peptostreptococcus spp. they are sensitive to antibiotics], most to penicillin and ATB and cefoxitin polypeptides. Other bacteria involved in the infection must be taken into account when assessing ATB.

Diagnostics
Diagnosis is determined from amniotic fluid, pus, abscess punctate and swab (for example from a wound), when we collect biological material anaerobically. [[Cultivation soils are cultivated on soils with low redox potential (VL-agar''') in anaerobic conditions.
