Abstract
Antibacterial susceptibility tests against 108 strains belonging to 9 genera, isolated from conjunctivitis, were carried out by disc diffusion method. These comprised Staphylococcus warnei (13 strains), S. intermedius (10), S. epidermidis (10), S. lugdunensis (10), S. simulans (7), S. auricularis (6), S. schleiferi (4), S. aureus (6), S. haemolyticus (2), S. capitis (2), S. saprophyticus (1), Micrococcus nishinomyaensis (5), M. varians (4), M. kristinea (2), M. sedentarius (1), Streptococcus morbillorum (4), S. pyogenes (1), Bacillus coagulans (1), B. sphaericus (2), B. firmus (4), Corynebacterium pseudodiphtheriticum (4), C. mycetoides (1), Pseudomonas aeruginosa (3), P. mallei (1), Moraxella osleonsis (2), Haemophilus aphrophilus (1), and Branhamella catarrhalis (1). In the present study 36.1% isolates were found resistant to ampicillin, 2.7% to chloramphenicol, 8% to clindamycin, 0.9% to gentamicin, 50% to polymyxin B, 14.8% to tetracycline and 1% to vancomycin while all isolates were susceptible to sulfonamides and trimethoprim. It was also observed that 28.7% strains were single-drug-resistant, 7.4% strains were resistant to 2 antibiotics while 0.9% strains were multi-drug-resistant.
