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

ABSTRACT

A cross-sectional descriptive clinic based study was carried out among 150 dysentery cases attending the three general practitioners clinics from February 1998 to June 1999. The cases comprised 62 percent males and 38 percent females. The age range was from six months to 72 years. The siolated 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 dysenteriae (40 percent)and Shigella sonnei (10 percent). The antibiotic susceptibility revealed that EPEC were sensitive to amikacin, augmentin, furazolidone, gentamicin, netilmicin, norfloxacin, nalidixic acid (83.3 percent) each, sisomycin and chloramphenicol (75 percent)each, cephalothin, streptomycin and neomycin (66.7 percent) each, and septrin (58.3 percent). They were resistant to ampicillin (66.7 percent), tetracycline (75 percent), and carbenicillin (66.7 percent). Shigella species were sensitive to netilmicin (100 percent), norfloxacin (100 percent), amikacin, augmentin, furazoli-done, gentamicin (80 percent) each, cephalothin, nalidixic acid, neomycin, septrin (70 percent)each. They were sesistant to streptomycin (100 percent),chloramphenicol (80 percent), tetracycline (80 percent), carbenicillin (70 percent)and ampicillin (60 percent).
