Polymicrobial diseases involve multiple infectious agents and are referred to as complex, complicated, mixed, synergistic, concurrent, coinfections. Polymicrobial diseases, caused by combinations of viruses, bacteria, fungi, and parasites, are being recognised with increasing frequency. In these infections, the presence of one microorganism generates a niche for other pathogenic micro-organisms to colonise, one micro-organism predisposes the host to colonisation by other micro-organisms, or two or more non-pathogenic micro-organisms together cause disease. This review summarizes past studies published by group on the microbiology of polymicrobial abscesses that occur at various body sites abscesses can show up any place on your body. The most common sites are in your armpits (axillae), areas around your anus and vagina(Bartholin gland abscess), the base of your spine (pilonidal abscess), around a tooth (dental abscess), and in your groin. Most of the peritonsillar abscess cases have a polymicrobial infection. Prevotella sp and Peptostreptococcus sp found. Anaerobic streptococci, Anaerobic Gram negative bacilli, Enterobacteriaceae, Streptococcus pneumoniae, β-haemolytic streptococciwas found to be the most common source of infection for anaerobic brain abscess. Staphylococcus aureus and Group A β-haemolytic streptococci are the most prevalent aerobes in skin and soft tissue abscesses and are isolated at all body sites. Group A β-haemolytic streptococci, pigmented Prevotella and Porphyromonas spp., and Fusobacterium spp. were most commonly found in lesions of the mouth, head, neck and fingers
