1. Modulators of Vibrio cholerae predator interaction and virulence
Abstract : Vibrio cholerae, the causal agent of cholera typically encodes two critical virulence factors: cholera toxin (CT), which is primarily responsible for the diarrhoeal purge, and toxin-co-regulated pilus (TCP), an essential colonisation factor. Nontoxigenic strains expressing TCP can efficiently acquire the CT gene through lysogenic conversion with CTXΦ, a filamentous phage that encodes CT and uses TCP as a receptor. READ MORE

2. Regulatory roles of sRNAs in pathogenesis of Vibrio cholerae
Abstract : The Gram-negative pathogen Vibrio cholerae uses variety of regulatory molecules to modulate expression of virulence factors. One important regulatory element of microorganisms is small non-coding RNAs (sRNAs), which control various cell functions such as expression of cell membrane proteins, mRNA decay and riboswitches.

3. Vibrio cholerae modulates the immune defense of human gut mucosa
Abstract : The key function of innate immunity is to sense danger signals and initiate effective responses as a defense mechanism against pathogens. Simultaneously, effector responses must be regulated to avoid excessive inflammation with resulting tissue damage. READ MORE

4. Structural and functional studies of the secreted metalloprotease PrtV from Vibrio cholerae
Abstract : Cholera, an acute diarrheal diseases caused by the intestinal infection of the pathogenic bacterium Vibrio cholerae, continues to be a global killer in the world today. PrtV, a secreted zinc metalloprotease, is a potent cytotoxic virulence factor of V. cholerae. READ MORE

5. Effect of virulence factors on survival strategies of vibrio cholerae and vibrio mimicus
Abstract : Vibrio is a genus of gram-negative bacteria comprising nearly 70 species and they are clinically human pathogens that can cause many infections. This study is mainly based on two species such as Vibrio cholerae O1 El Tor, which cause cholera disease and Vibrio mimicus, that cause gastroenteritis, open wounds infection, and septicemia.
