India experienced two plague outbreaks in Gujarat and Maharastra during 1994 and then in the Shimla district of Himachal Pradesh during 2002. Yersinia pestis strains recovered from rodents and pneumonic patients during the 1994 outbreaks, pneumonic patients from the 2002 Shimla outbreak and rodents trapped on the Deccan Plateau during a surveillance(More)
Members of the family Enterobacteriaceae are major pathogens associated with gastrointestinal disorders caused by the consumption of contaminated foods. We have developed a multiplex PCR (mPCR) targeting specific genes for simultaneous detection and differentiation of five major Enterobacteriaceae members, namely, Salmonella sp. (invA), Escherichia coli(More)
In the present study, a bivalent chimeric protein rVE comprising immunologically active domains of Yersinia pestis LcrV and YopE was assessed for its prophylactic abilities against Yersinia enterocolitica O:8 infection in murine model. Mice immunized with rVE elicited significantly higher antibody titers with substantial contribution from the rV component(More)
A three component complex system, designated hemolysin BL (HBL), is believed to be the major diarrheal toxin of Bacillus cereus. Identification of HBL toxin by immunoassay is advantageous over PCR as it detects the expressed form of the gene, thereby differentiating pathogenic strains from nonpathogenic strains. However, most of the immunoassays, like the(More)
Clostridium perfringens and Staphylococcus aureus are the two important bacteria frequently associated with majority of the soft tissue infections. The severity and progression of the diseases caused by these pathogens are attributed primarily to the alpha toxins they produce. Previously, we synthesized a non-toxic chimeric molecule r-αCS encompassing the(More)
In this study, the immunogenicity and protective efficacy of recombinant proteins Omp19 (rO) and P39 (rP) from Brucella abortus were evaluated individually and compared with the cocktail protein (rO+rP) against B. abortus 544 and Brucella melitensis 16M infection in BALB/c mouse model. Intra-peritoneal (I.P.) immunization with rO+rP cocktail developed(More)
Clostridium perfringens alpha toxin/phospholipase C (CP-PLC) is one of the most potent bacterial toxins known to cause soft tissue infections like gas gangrene in humans and animals. It is the first bacterial toxin demonstrated to be an enzyme with phospholipase, sphingomyelinase and lecithinase activities. The toxin is comprised of an enzymatic N-domain(More)
Anthrax, a fatal zoonotic disease caused by spore forming bacteria Bacillus anthracis is predominantly witnessed among herbivorous animals that are highly susceptible to the pathogen. Typically B. anthracis spores existing in soil, initiate the infection during grazing and animal to animal spread has been rarely reported. A suspected outbreak of anthrax was(More)
Vibrio vulnificus hemolysin A (VvhA) is a pore forming toxin and plays an important role in the pathogenesis. The hemolytic and cytotytic property of VvhA toxin is associated with N-terminal leukocidin domain which triggers apoptotic signaling cascade in epithelial cells. The present study was undertaken to assess the protective efficacy of recombinant VvhA(More)
