HeLa cell association was examined in eight Rhodococcus equi isolates containing 80-85 kb plasmids and their plasmid negative derivatives, and in two other plasmid negative R. equi strains. Seven of the eight plasmid positive strains possessed an 85 kb plasmid and produced the virulence-associated protein (VapA) detected by monoclonal antibody staining in(More)
A physical map of the 85 kb virulence plasmid pOTS from Rhodococcus equi 103 was constructed. The restriction map contains 2 AsnI, 5 BglII, 9 EcoRI, 4 HindIII, and 3 XbaI sites. The positions of the EcoRI and HindIII of pOTS are identical to that of the 85 kb virulence plasmid of R. equi ATCC 33701 reported recently by others. EcoRI restriction fragment(More)
Four isolates of Rhodococcus equi, from pneumonic foals, and containing the 85 kb virulence plasmid, a porcine isolate containing an 80 kb plasmid, and their plasmid cured derivatives, were examined for 239 phenotypic properties in an attempt to find characters other than the virulence-associated protein (VapA) which might be encoded by the virulence(More)
One hundred and twenty-five serum samples from California sea lion (Zalophus californianus californianus) pups, and one from an adult female from eight reproductive rookeries located in seven islands in the Gulf of California (Mexico), were collected during the 1994-96 reproductive seasons. These were tested for antibodies to 19 serovars of Leptospira(More)
We conducted an immunological assay of blood samples taken from 85 swine-specialist veterinarians attending the Congress of the Mexican Association of Swine Specialist Veterinarians in Mexico in 2011. Serum samples were assayed for Porcine rubulavirus (PorPV), Encephalomyocarditis virus (EMCV) and Leptospira spp. antibodies. Using a hemagglutination(More)
