Epidemic cholera caused by toxigenic Vibrio cholerae O1 is a major health problem in several developing countries. Traditional methods for identifying V. cholerae involve cultural, biochemical and immunological assays which are cumbersome and often take several days to complete. In the present study, a direct cell multiplex PCR was developed targeting the ompW, ctxB and rfbO1 genes for confirma...
24 Vibrio cholerae serotype O1 causes diarrhea in many developing countries around the world. In most cases, cholera patients pose some sorts of immunity against the naturally occurring infection. In the present study, the bactericidal activity of the sera of rabbit immunized with whole cell extract of Vibrio cholerae O1 was investigated. The protein profile of the serotype exhibited 20 types o...
Ontology mappings are often assigned a weight or confidence factor by matchers. Nonetheless, few semantic accounts have been given so far for such weights. This paper presents a formal semantics for weighted mappings between different ontologies. It is based on a classificational interpretation of mappings: if O1 and O2 are two ontologies used to classify a common set X , then mappings between ...
isolate more phages in Brazil and neighboring countries. To date, serotyping is the only identification tool for the characterization of non-O1 strains of V. cholerae (8). However, serotyping is only performed at a limited number of laboratories. For this study, all isolates from Brazil were sent to laboratories outside the country for serotyping. This step was expensive and timeconsuming and p...
The genetic relatedness of 81 isolates of Vibrio parahaemolyticus was assessed by multilocus sequence typing. The strain with serotype O3:K6 emerged as a pandemic pathogen in 1996, with subsequent expansion to include strains having serotypes O1:KUT, O4:K68, and O1:K25. Sequence data from gyrB, recA, dnaE, and gnd revealed that 16 distinct serogroups isolated prior to the pandemic were highly v...
I have defined the basic requirements for the proliferation of cell lines expressing oligodendrocyte properties and for the survival of galactocerebroside-positive oligodendrocytes derived from neonatal rat brains. Conventional serum-containing medium can be replaced by 01 medium, a chemically defined medium supplemented with insulin, transferrin, sodium selenite, and biotin. Thyroid hormone is...
A fish pathogen, Vibrio cholerae non-O1, was isolated from diseased ayu fish (Plecoglossus altivelis) collected from rivers in eight prefectural districts of Japan. This organism was found to have biochemical characteristics similar to those of V. cholerae non-O1, except that our isolates were negative for ornithine decarboxylase. Antiserum against an ayu isolate did not agglutinate with the ma...
O1 Truncal asymmetry in school children: the effect of the parental age at birth TB Grivas, C Mihas, C Mazioti, S Sakellaropoulou, N Zisis, A Akriotis, RG Burwell Department of Trauma and Orthopaedics, “Tzanio” General Hospital of Piraeus, Piraeus, Greece; General Hospital of Kimi, Kimi, Greece; “Tzanio” General Hospital of Piraeus, Piraeus, Greece; “Tzanio” General Hospital of Piraeus, Greece;...
Vibrio cholerae O1 strains belonging to both biotypes (classical and El Tor) and both serotypes (Ogawa and Inaba) produced neuraminidase which was released rather than cell bound. Classical strains made more neuraminidase than did El Tor strains. About one-third of V. cholerae non-O1 strains and one-fourth of Aeromonas hydrophila strains were neuraminidase positive. Strains of enterotoxigenic E...
