Pathogenic strains of Vibrio cholerae are lysogens of the filamentous phage CTXphi, which carries the genes for cholera toxin (ctxAB). We found that the titers of infective CTXphi in culture supernatants of El Tor CTXphi lysogens increased rapidly during exponential growth but dropped to undetectable levels late in stationary-phase growth. When CTXphi transducing particles were mixed with stati...
A total of 431 rectal swabs, collected from acute diarrheal cases at a surveillance site and at different diarrheal outbreak areas of Orissa from May to October 2005, were bacteriologically analyzed. Out of 265 culture-positive samples, Vibrio cholerae O1 was isolated in 56 samples (20.8%), of which 37 were the Inaba serotype and 19 were the Ogawa. The antibiogram profile revealed that all the ...
Vibrio cholerae O1 biotype El Tor (ET), the cause of the current 7th pandemic, has recently been replaced in Asia and Africa by an altered ET biotype possessing cholera toxin (CTX) of the classical (CL) biotype that originally caused the first six pandemics before becoming extinct in the 1980s. Until recently, the ET prototype was the biotype circulating in Peru; a detailed understanding of the...
Completion-based algorithms can be employed for computing the least common subsumer of two concepts up to a given role-depth, in extensions of the lightweight DL EL. This approach has been applied also to the probabilistic DL Prob-EL, which is variant of EL with subjective probabilities. In this paper we extend the completion-based lcscomputation algorithm to nominals, yielding a procedure for ...
B acteriophage can convert their bacterial host from a nonpathogenic form to a pathogenic form by providing the bacterium with virulence genes, in a process called lysogenic phage conversion. Vibrio cholerae is a bacterium prevalent in marine environments that can infect humans to cause the devastating diarrheal disease cholera, which is endemic in much of Asia and Africa. Although the health a...
