1. Fatores de patogenicidade de Vibrio spp. de importância em doenças transmitidas por alimentos
RESUMO: As bactérias do gênero Vibrio habitam ambiente tipicamente marinho e estuarino, sendo comumente isoladas de pescados. As principais espécies de Vibrio reportadas como agentes de infecções em humanos são V. vulnificus , V. parahaemolyticus , V. cholerae e V. mimicus . V. vulnificus é considerado o mais perigoso, podendo causar septicemia e leva

2. Hemolytic and urease activities in vibrios isolated from fresh and frozen oysters
INTRODUCTION: The present study aimed to survey the Vibrio microbiota of oysters (Crassostrea rhizophorae) obtained from restaurants in Fortaleza, State of Ceará, Brazil, and to identify virulence factors. METHODS: The isolated vibrios were submitted to biochemical identification and were tested for hemolytic and urease activities. RESULTS: The isolated str

3. VÃbrio em camarÃo e na Ãgua de trÃs fazendas de carcinicultura do Cearà / Vibrio in shrimp and water from three shrimp farms in CearÃ
O presente estudo teve por objetivo quantificar Vibrio, vibrios sac+ e sac â e identificar as espÃcies de Vibrio, presentes no cultivo do camarÃo Litopenaeus vannamei e na Ãgua onde à ele cultivado. Acompanharamse dois ciclos do cultivo do L. vannamei em trÃs fazendas (A, B e C),situadas nos estuÃrios dos rios AcaraÃ, Coreaà e Jaguaribe (CE), de ago

4. The Zymovars of Vibrio cholerae: Multilocus Enzyme Electrophoresis of Vibrio cholerae
Zymovars analysis also known as multilocus enzyme electrophoresis is applied here to investigate the genetic variation of Vibrio cholerae strains and characterise strains or group of strains of medical and epidemiological interest. Fourteen loci were analyzed in 171 strains of non-O1 non-O139, 32 classical and 61 El Tor from America, Africa, Europe and Asia.

5. Infectious CTXΦ and the Vibrio Pathogenicity Island Prophage in Vibrio mimicus: Evidence for Recent Horizontal Transfer between V. mimicus and V. cholerae
Vibrio mimicus differs from Vibrio cholerae in a number of genotypic and phenotypic traits but like V. cholerae can give rise to diarrheal disease. We examined clinical isolates of V. mimicus for the presence of CTXΦ, the lysogenic filamentous bacteriophage that carries the cholera toxin genes in epidemic V. cholerae strains. Four V. mimicus isolates were f

6. Coagglutination of Vibrio cholerae, Vibrio mimicus, and Vibrio vulnificus with anti-flagellar monoclonal antibody.
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-l

7. Sources of Vibrio mimicus Contamination of Turtle Eggs
Vibrio mimicus contamination of sand increased significantly during the arrival of the olive ridley sea turtles (Lepidochelys olivacea) at Ostional anidation beach, Costa Rica. Statistical analysis supports that eggs are contaminated with V. mimicus by contact with the sand nest. V. mimicus was isolated from eggs of all nests tested, and ctxA+ strains were f

8. Development of a Hexaplex PCR Assay for Rapid Detection of Virulence and Regulatory Genes in Vibrio cholerae and Vibrio mimicus
We have developed a hexaplex PCR assay for rapid detection of the virulence and regulatory genes for cholera toxin enzymatic subunit A (ctxA), zonula occludens toxin (zot), accessory cholera enterotoxin (ace), toxin-coregulated pilus (tcpA), outer membrane protein (ompU), and central regulatory protein ToxR (toxR) in Vibrio cholerae and Vibrio mimicus. This

9. Differentiation of Environmental and Clinical Isolates of Vibrio mimicus from Vibrio cholerae by Multilocus Enzyme Electrophoresis
In this study, we demonstrated that analyzed strains of Vibrio mimicus and Vibrio cholerae could be separated in two groups by using multilocus enzyme electrophoresis (MEE) data from 14 loci. We also showed that the combination of four enzymatic loci enables us to differentiate these two species. Our results showed that the ribosomal intergenic spacer region

10. Characterization of biochemically atypical Vibrio cholerae strains and designation of a new pathogenic species, Vibrio mimicus.
Biochemically atypical strains classified as Vibrio cholerae were characterized by biochemical reactions, serology, antibiotic susceptibility testing, and deoxyribonucleic acid relatedness. Strains with the following atypical reactions were shown to be V. cholerae: mannose negative, mannitol negative, lysine decarboxylase negative, no growth in the presence

11. Purification and characterization of a protease produced by Vibrio mimicus.
A protease produced by Vibrio mimicus was purified to apparent homogeneity by ammonium sulfate fractionation and successive column chromatography on Sephacryl S-100 and Mono Q Monobeads. The sodium dodecyl sulfate-polyacrylamide gel electrophoresis (PAGE) of the final preparation of the enzyme revealed the homogeneity of the purified enzyme. Conventional PAG

12. Analysis of 16S-23S rRNA Intergenic Spacer Regions of Vibrio cholerae and Vibrio mimicus
Vibrio cholerae identification based on molecular sequence data has been hampered by a lack of sequence variation from the closely related Vibrio mimicus. The two species share many genes coding for proteins, such as ctxAB, and show almost identical 16S DNA coding for rRNA (rDNA) sequences. Primers targeting conserved sequences flanking the 3′ end of the 1
