Epidemiological studies of shigellosis in Bangladesh have demonstrated that surface-water sources can act as foci of infection. Studies of laboratory microcosms have shown that shigellae become nonculturable but remain viable when exposed to environmental samples of water. The present study was carried out to detect viable but nonculturable Shigella dysenteriae 1 from laboratory microcosms by t...

A new born baby was admitted to the Glocal hospital, Krishnanagore, and presented with loose stools mixed with blood and mucous and abdominal distension for last five days. The baby was crying all through the day; presumably, he had severe tenesmus (a feeling of incomplete sense of defecation with rectal pain). He was diagnosed, clinically, to be suffering from shigellosis, which was confirmed ...

The Micro-Media Quad Enteric Panel and coding system were evaluated by comparing the identifications of 193 stock and 216 clinical isolates, representing 31 species of Enterobacteriaceae, with those provided by conventional methods. The results corresponded for 91% of the organisms if only the single or most probable identification was accepted and for 93% if the correct identification was list...

Because of the metabolic and antibacterial actions of short-chain fatty acids (SCFA), their roles in modifying the clinicopathologic features of shigellosis were evaluated in a rabbit model of shigellosis. Acute colitis was induced in adult rabbits by intracolonic administration of Shigella flexneri 2a. After 24 h, rabbits were given 6-h colonic infusions of SCFA (acetate, propionate, n-butyrat...

Shigellosis is an important cause of morbidity and mortality in India. In contrast to what was reported for the developed world and Iran (1), where Shigella sonnei is common, the occurrence of nalidixic acid resistance is low, and no isolates have been determined to be resistant to fluoroquinolones, for the Indian subcontinent, Shigella flexneri continues to be the most common serogroup isolate...

A series of bacteriophages specific for Escherichia coli (E-1, E-2, E-3, and E-4), Citrobacter freundii (phi I, phi II, and phi III), Enterobacter cloacae (Ent), and Shigella spp. (Sh) have been isolated from hospital sewage. These bacteriophages, in combination with Felix Salmonella phage O-I, were used as a diagnostic phage typing set which included seven phage preparations: O-I, C (phi I and...
