Bacillary dysentery caused by Shigella species is a public health problem in developing countries including Bangladesh. Although, shigellae-contaminated food and drinks are often the source of the epidemic's spread, the possible presence of the pathogen and transmission of it through environmental waters have not been adequately examined. We analyzed surface waters collected in Dhaka, Banglades...

Principal component analysis (PCA) was used to comprehensively evaluate the relationship between physicochemical and bacteriological parameters of water on banks Wouri. At each sampling station, focused Water temperature, pH, dissolved oxygen, CO2, electrical conductivity, suspended solids, nitrates, ammonium ions, orthophosphates, color, salinity, turbidity. The consisted isolation heterotroph...

Shigellosis is a severe diarrheal disease caused by members of the genus Shigella , with at least 80 million cases and 700,000 deaths annually around world. The type III secretion system (T3SS) primary virulence factor used shigellae, we have previously demonstrated that vaccination T3SS proteins IpaB IpaD, along an IpaD/IpaB fusion protein (DBF), protects mice from infection in lethal pulmonar...

The ipaH loci comprise a multicopy antigen gene family unique to Shigella species and enteroinvasive Escherichia coli (EIEC). DNA probes derived from the Shigella flexneri serotype 5 ipaH7.8 gene were used to compare the molecular arrangement of ipaH alleles in a variety of Shigella and EIEC strains. Multiple copies of ipaH-homologous sequences were detected in all invasion plasmids examined. O...

This report deals with serological and biochemical relationships between members of the genus Escherichia and Escherichia-like paracolon bacteria and the microorganisms that are usually classified as Shigella di8par. These studies are part of an investigation on the interrelationships within the family Enterobacteriaceae that was started in 1942 and which is still in progress. Shigella ceylonen...
