Anaerobes can infect normal hosts and hosts with compromised resistance or damaged tissues. Anaerobic infections can include both single anaerobic species or multiple anaerobic species with any number of nonanaerobic isolates. Symptoms depend on site of infection. Diagnosis is clinical combined with Gram stain and anaerobic cultures.
