Abstract
Vibrio parahaemolyticus is a major foodborne pathogen responsible for significant economic losses in aquaculture and a threat to human health. Here, we explored the incidence, virulence potential, and diversity of V. parahaemolyticus isolates from aquaculture farms in Bangladesh. We examined a total of 216 water, sediment, Oreochromis niloticus (tilapia), Labeo rohita (rui), and Penaeus monodon (shrimp) samples from the aquaculture system where 60.2% (130/216) samples were positive for V. parahaemolyticus. Furthermore, we identified 323 V. parahaemolyticus strains from contaminated samples, 17 of which were found positive for trh, a virulence gene. Four isolates out of the 17 obtained were able to accumulate fluid in the rabbit ileal loop assay. The correlation between the contamination of V. parahaemolyticus and environmental factors was determined by Pearson correlation. The temperature and salinity were significantly correlated (positive) with the incidence of V. parahaemolyticus. Most of the pathogenic isolates (94.1%) were found resistant to ampicillin and amoxicillin. O8: KUT was the predominant serotype of the potentially pathogenic isolates. ERIC-PCR reveals genetic variation and relatedness among the pathogenic isolates. Therefore, this region-specific study establishes the incidence of potential infection with V. parahaemolyticus from the consumption of tilapia, rui, and shrimp raised in farms in Satkhira, Bangladesh, and the basis for developing strategies to reduce the risk for diseases and economic burden.

Abstract
The present work aims at identification of multiple drug-resistant pathogenic bacteria in a selected stretch, namely, Puri on the Bay of Bengal, India. Six stations at the coast of Puri were selected and samples of water and sediment were collected during the winter of 2008 and 2009 for this study. Thirty-eight pathogenic bacteria were isolated and identified from both the water and the sediment of 6 fixed stations (PU-1a, PU-1b, PU-2, PU-3, PU-4, and PU-5). The identified pathogens were Escherichia coli, Vibrio cholerae, Vibrio parahaemolyticus, Klebsiella pneumoniae, Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Proteus mirabilis. Antibiotic sensitivity of the isolated bacteria was studied by using 12 selected antibiotics, commonly used for the medication of human beings and animals. The isolated pathogens from both the water and the sediment samples showed lowest resistance to chloramphenicol (C-30 μg) where as the pathogens showed highest level of resistance to ampicillin (10-μg) among the antibiotics used for the study. Among the isolated pathogens E. faecalis (PU-1a), P. aeruginosa (PU-2 and PU-3), E. coli (PU-3 and PU-4), and K. pneumonia (PU-4) showed resistance to more than four antibiotics. Out of the isolated species, 57.8% pathogens were multi-drug resistant. Antibiotic resistance indexes of all the stations were calculated and found to be in the range of 0.066 to 0.083.

Abstract
Monoclonal antibodies (MAbs) with serological activity for purified flagellar (H) core protein prepared from Vibrio cholerae were identified by enzyme-linked immunosorbent assay. Four of these MAbs reacted with the flagella of V. cholerae and V. mimicus exclusively, while eight MAbs reacted with at least 1 of 30 heterologous Vibrio species tested by enzyme-linked immunosorbent assay or coagglutination. It appears that V. cholerae and V. mimicus express similar, if not identical, H determinants unique to these two Vibrio species. Staphylococcus aureus cells or latex beads armed with the four species-specific MAbs coagglutinated each of 47 isolates identified bacteriologically as V. cholerae or V. mimicus from among 103 Vibrio isolates tested. One coagglutination reagent armed with anti-V. vulnificus H MAb exhibited species specificity in that only V. vulnificus cells were coagglutinated from among the 31 Vibrio species examined. This reagent coagglutinated 20 isolates identified bacteriologically as V. vulnificus in a serological survey. MAb coagglutination reagents offer a rapid, specific, and economical alternative to the classical bacteriological approach to identify the human pathogens V. cholerae, V. mimicus, and V. vulnificus.

Abstract
Staphylococcus aureus Cowan 1 cells were armed with anti-flagellar (anti-H) antibody produced in rabbits immunized with flagellar core protein prepared from Vibrio vulnificus. This reagent was assessed by coagglutination for its capacity to agglutinate and identify V. vulnificus. A species-specific H antigen is expressed in the core proteins of the polar flagella of V. vulnificus. Of 435 V. vulnificus isolates identified bacteriologically, 432 (99.3%) were agglutinated in the slide test within 2 min after the addition of the anti-V. vulnificus H coagglutination reagent. Other than Vibrio pelagius, the reagent did not agglutinate 19 heterologous Vibrio spp. tested, including 290 V. cholerae, 22 V. mimicus, 395 V. parahaemolyticus, and 16 V. fluvialis isolates recovered from seafood and the marine environment. The serological resolution of the coagglutination reaction was enhanced if the organism under test was suspended in 0.1 M Tris buffer-0.1 mM EDTA-1.0% Triton X-100 (TET) for 24 h before serological examination. The TET buffer also increased the sensitivity of the coagglutination reaction 100-fold over that for isolates suspended in 0.3% formalinized phosphate-buffered saline before testing. The anti-H coagglutination test is a rapid, serologically specific, and inexpensive procedure for identifying V. vulnificus one step beyond primary isolation.

Abstract
The antigenicity of lateral (L-) flagella of two marine vibrios, Vibrio alginolyticus and V. harveyi, was studied, and the two species were found to have common antigenicity of their flagella. Antisera against L-flagella were prepared by immunizing rabbits with highly purified L-flagellar filaments. H-Agglutination tests with the anti-L-flagella antisera showed that four H-serovars existed in these species and that two of them were shared by the two species. Cross reactivity between H-serovars of these two species and other vibrios having lateral flagella, such as V. parahaemolyticus, V. campbellii, V. proteus, or V. fluvialis, was not observed in the H-agglutination test, although partial common antigenicity was observed in the gel diffusion test with flagellin monomers. These observations suggest that surface antigenic determinants of the lateral flagella of V. alginolyticus and V. harveyi are specific to these two species but internal antigenic determinants buried in the flagellar filaments are partially shared with other vibrio species.
