| Abstract: | In 1998, the worst flood disaster in Bangladesh ravaged more than half of its land and diarrheal epidemics broke out. We examined fecal specimens of diarrheal patients at rural hospitals in Chandpor district located 140 km southeast of Dhaka to analyze the enteric bacterial pathogens in post-flood period October. Of the 76 patients stools examined, Vibrio cholerae O1 biotype El Tor, serotype Ogawa, and Vibrio cholerae O139 Bengal were detected in 25 (33%) and in 14 (18%) respectively. Other enteropathogenic bacteria confirmed were Vibrio cholerae O5, Vibrio fluvialis and Enteropathogenic Escherichia coli O44. Neither Shigella nor Salmonella species was detected in this study. A drug susceptibility test was performed using TC, DOXY, CPFX, NA, and AMPC disks to cholera Vibrios. The O1 Vibrios showed the same susceptible pattern as O139 excluding NA susceptibility. TC resistant strain among the Vibrios was not detected though TC is a common therapeutic drug for diarrhea in this area. Our result clearly suggested that the epidemic potentiality of O139 still existed in rural Bangladesh. |
