Current trends of antibiotic susceptibility pattern of bacterial pathogens isolated from dysentery cases from clinics

ABSTRACT

A cross-sectional descriptive clinic based study was carried out among 150 dysentery case attending the three general practioners' clinic from February 1998 to June 1999.The cases comprised 62 patients males and 38 percent females.The age range was from six month to 72 years.The isolated bacterial pathogens were Enteropathogenic Escherichia Coli (EPEC) (8 percent); Enterotoxigenic Escherichia coli (ETEC) (6.7 percent); shigella species (6.7 percent), out of which were Shigella Flexneri (50 percent), shigella dysenteiae (40 percent) and shigella sonnei(10 percent).The antibiotics susceptibility revealed that EPEC were sensitive to amikacin, augmentin, furazolidone, gentamicin, netilmicin, norfloxacin, nalidixic acid (83.3 per cent ) each; sisomycin and chloramphenicol (75 per cent ) each, cephalothin, streptomycin and neomycin (66.7 percent) each, septrin (58.3 percent).They were resistant to ampicillin (66.7 percent), tetracycline (75 percent) and carbinicillin (66.7 percent).Shigella species were sensitive to netilmicin (100 percent), norfloxacin (100 percent), amikacin, augamentin, furazolidone, gentamicin (80 percent) each, cephalothin, nalidixic acid, neomycin, septrin (70 percent) each.They were resistant to streptomycin (100 percent), chloramphenicol (80 percent), tetracycline (80 percent), carbenicillin (70 percent) and ampicillin (60 percent).
