ABSTRACT
A total of 55 cases of children with dysentery admitted to the Defence Services Obstetric, Gynaecology and Children Hospital and North Okkalapa General Hospital were included in this study. It was found that 49.1 per cent of the children were suffering from shigella bacillary dysentery. The Shigella spp. isolated were: Shigella flexneri (44.4 per cent), Shigella dysenteriae (29.6 per cent), Shigella boydii (22.2 per cent) and Shigella sonnei (3.7 per cent). the distribution of Shigella spp. among the different age groups were 42.9 per cent in the age group of less than 6 months, 40 per cent in 6 to 12 months, 55 per cent in 13 to 24 months and 66.7 per cent in 25 to 60 months. Antibiotic susceptibility test revealed that these shigellae were resistant to ampicillin (84 per cent), chloramphenicol (76 per cent), streptomycin (84 per cent), tetracycline (64 per cent) and septrin (72 per cent); were fully sensitive to amikacin, gentamycin, netilmicin, norfloxacin and were less sensitive to cephalothin (76 per cent) and furazolidone (72 per cent).
