The detection microscopically of colonies of shigella in stool cultures.
Early recognition of the presence of Shigella in the stool of a patient facilitates use of the most specific therapy and proper consideration of epidemiologic implications. The positive diagnosis of a Shigella infection requiies isolation of the etiologic agent from the stool of the patient and its identification by biochemical and serological studies which usually require a minimum of 36 to 48...
متن کاملThree-tube method for screening stool cultures for Salmonella and Shigella.
A three-tube method developed is described as a screening test for non-lactose-fermenting organisms isolated from stool cultures. To evaluate the method, 976 strains of gram-negative bacilli were tested. All strains of Salmonella and Shigella were correctly identified generically.
متن کاملCurli loci of Shigella spp.
An unstable chromosomal element encoding multiple antibiotic resistance in Shigella flexneri serotype 2a was found to include sequences homologous to the csg genes encoding curli in Escherichia coli and Salmonella enterica serovar Typhimurium. As curli have been implicated in the virulence of serovar Typhimurium, we investigated the csg loci in all four species of Shigella. DNA sequencing and P...
متن کاملDipstick for Rapid Diagnosis of Shigella flexneri 2a in Stool
BACKGROUND Shigellosis or bacillary dysentery, an acute bloody diarrhoea, is a major public health burden in developing countries. In the absence of prompt and appropriate treatment, the infection is often fatal, particularly in young malnourished children. Here, we describe a new diagnostic test for rapid detection, in stool, at the bedside of patients, of Shigella flexneri 2a, the most predom...
متن کاملEvaluation of Urea-motility-indole medium for recognition and differentiation of Salmonella and Shigella species in stool cultures.
A semisolid urea-motility-indole medium designed for detection in Enterobacteriaceae of urease activity, motility, and indole production in one tube was prepared and evaluated. The formulation of the medium was similar to that of Christensen urea agar, but the agar concentration was 0.2%, and 1% tryptone was added. Results with 687 strains of Enterobacteriaceae were the same as those obtained w...
