Background: This study compared the diversity of common diarrhoeal pathogens and antimicrobial susceptibility in four hospitals in Bangladesh. Methodology: A total of 13,959 diarrhoea patients, comprising rural Mirzapur [2,820), rural Matlab (2,865), urban Dhaka (5,287) and urban Mirpur (2,987) were included under the diarrhoeal disease surveillance system of icddr,b during 2010-2011; stool specimens were tested for Shigella spp., Vibrio cholerae, enterotoxigenic Escherichia coli and rotavirus. Results: Rotavirus was highest in Mirzapur (28%) followed by Dhaka (24%), Matlab (19%) and Mirpur (18%). Overall, Shigella was significantly more prevalent in rural sites (Mirzapur 13% and Matlab 7%), than in urban sites (Dhaka 3% and Mirpur 3%). Vibrio cholerae was more common in the urban sites of Dhaka (14%) and Mirpur (12%). 72% of Shigella isolates were susceptible to ciprofloxacin in Mirzapur, and 88% to mecillinam. In Dhaka, the figures for Shigella were 65% and 50%, in Matlab 65% and 85%, and in Mirpur 59% and 92% respectively. Susceptibility of Shigella to azithromycin and ceftriaxone in Dhaka was 74% and 95%, and in Mirpur 88% and 92% respectively. Vibrio cholerae showed the highest resistance to trimethoprim-sulfamethoxazole (100% in Mirpur) and lowest resistance to ciprofloxacin (0% in Dhaka, Matlab and Mirpur) and azithromycin (30% in Dhaka to 7% in Mirzapur). Multidrug resistance (≥ 3 antibiotics) for Shigella were: Mirzapur (50%); Dhaka (36%); Matlab (23%) and Mirpur (37%); and for V. cholerae it was 26%, 37%, 49% and 23% respectively. Conclusion: The isolation rates and antimicrobial susceptibility of Shigella spp. and V. cholerae along with rotavirus differed significantly in certain geographical sites.
