Anorectal abscesses: bacterial isolation and antimicrobial resistance

ABSTRACT

A total of 68 cases of pus or pus swabs were received at the laboratory of Abbasi Shaheed Hospital, Karachi from anorectal absecesses. They were collcted from 1993 to 1996. All samples were subjected to culture of which 53 [77.94%] showed growth. The organisms isolated from positive sample were Escherichia coli 22 [41.51%], Staphyloccus aureus 19 [35.85%], Staphyloccus epidermidis 4 [7.55%], Proteus vulgaris 3 [5.66%], Pseudomonas aeruginosa 3 [5.66%] and Streptococcus pyogenes 2 [3.77%]. Different antibiotic sensitivity and resistance patterns were found for different organisms. There was increased antimicrobial resistance observed in the present study. Proper identification, isolation and sensitivity pattern of organism is essential for successful treatment besides adequate dosage of antibiotics for appropriate duration of time By using this methodology we will decrease the chances of drug resistance in our population
