Isolation and characterisation of bacteria from abscesses in the subcutis of cats

Abstract

Thirty-six closed abcesses in the subcutis of cats were examined. Of 168 bacterial strains isolated, 121(72%) were anaerobes and 47 (28%) were facultative anaerobes. Twenty-six abscesses contained mixtures of facultative anaerobes and anaerobes, six contained anaerobes only and four contained facultative anaerobes only. Bacteriodes was the genus most commonly isolated (28.6% of all isolates) followed by Fusobacterium (19.0%) and Pasteurella (multocida) (13.1%). Peptostreptococcus anaerobius was the most commonly isolated anaerobic species (13.2% of anaerobic isolates and 9.5% of all isolates)and Past, multocida was the most commonly isolated facultative anaerobe (46.8%; 13.1%of all isolates).
