Comparison of Distribution of Virulence Determinants in Clinical and Environmental Isolates of Vibrio cholera
Background: The virulence of a pathogenic Vibrio cholerae is dependent on a discrete set of genetic determinants. In this study, we determined the distribution of virulence determinants among the clinical and environmental isolates of V. cholerae. Methods: The antibiotic resistance profiles of the isolates were determined using standard disk diffusion assay. PCR assay was performed to analyze t...
متن کاملVirulence Determination among Vibrio Harveyi Hatchery Isolates through Haemolysis and Growth Constraint
Bacterial diseases mainly due to vibriosis in Penaeid shrimp culture implicating several species of Vibrios. Vibrio harveyi is considered as an important causative agent of the systemic vibriosis, which occurs in any bio-fields. The virulence of this bacterium is due to the production and expression of several virulent factors such as hemolysin, cysteine and metalloprotease, phospholipases, exo...
متن کاملNovel beta-lactamase genes from two environmental isolates of Vibrio harveyi.
Two ampicillin-resistant (Amp(r)) isolates of Vibrio harveyi, W3B and HB3, were obtained from the coastal waters of the Indonesian island of Java. Strain W3B was isolated from marine water near a shrimp farm in North Java while HB3 was from pristine seawater in South Java. In this study, novel beta-lactamase genes from W3B (bla(VHW-1)) and HB3 (bla(VHH-1)) were cloned and their nucleotide seque...

متن کاملIdentification of upregulated immune-related genes in Vibrio harveyi challenged Penaeus monodon postlarvae.
A subtracted cDNA library was constructed and analyzed to elucidate the response of Penaeus monodon postlarvae challenged with Vibrio harveyi. As many as 960 randomly selected cDNA fragments generated through suppression subtractive hybridization were single pass sequenced. Forty five genes and 20 hypothetical proteins were identified, a few being first reports from shrimps. The most abundant i...
