| antigenic relationships of moraxella bovis isolates recovered from outbreaks of infectious bovine keratoconjunctivitis in argentina, brazil, and uruguay between 1983 and 2000. | cross-reactivity indices (cris) of 28 isolates of moraxella bovis recovered from outbreaks of infectious bovine keratoconjunctivitis in argentina (a, 11 isolates), brazil (b, 7), and uruguay (u, 10) between 1983 and 2000 were estimated. hyperimmune sera were produced in rabbits and antibody titres determined with each isolate. isolates showing cris3 70 were placed in the same group. group i had 13 isolates (a, 1; b, 6; u, 6); group ii had 6 isolates (a, 4; u, 2); groups iii, iv, and v had 2 isol ... | 2003 | 14620871 |
| molecular diversity of moraxella bovis isolated from brazil, argentina and uruguay over a period of three decades. | the molecular profile of 30 moraxella bovis strains, recovered from outbreaks of infectious bovine keratoconjunctivitis in argentina, brazil and uruguay between 1974 and 2001, was determined through randomly applied polymorphic dna (rapd) analysis. molecular profiles of nine strains recovered after 1990 varied from those recovered before 1990. the profiles of 13 strains (48%) differed from those of three vaccinal strains extensively used since 1984 in argentina and uruguay. eight argentinean str ... | 2004 | 14623151 |
