 Frequency of infections is greater in developing countries because treatment is often slow, or it is impossible to get the adequate treatment, but mortality due to "peptostreptococcus" infections have decreased in the last 30 years and will continue to do so due to better treatment.All ages are susceptible to "peptostreptococcus" infections, however children are more likely to get head and neck infections.Anaerobic gram-positive cocci and microaerophilic streptococci are often recovered in polymicrobial skin and soft tissue infections, such as gangrene, fasciitis, ulcers, diabetes-related foot infections, burns, human or animal bites, infected cysts, abscesses of the breast, rectum, and anus.
