| brucella abortus in coyotes. i. a serologic and bacteriologic survey in eastern texas. | prevalence of brucella abortus serum antibodies in coyotes from east central texas was determined by the buffered brucella antigen (card test), rivanol, standard agglutination tube, and cold complement fixation tube tests. eighteen percent (9 of 51) of the coyotes were positive serologically. b. abortus biotype 1 was isolated from various tissues from 7 of 43 coyotes by bacteriologic culture. congenital transmission was found. | 1979 | 116012 |
| comparison of results from five serologic methods used for detecting brucella abortus antibody activity in coyote sera. | a total of 423 serum samples representing 94 coyotes which were wild trapped in east texas were used to compare the serologic results from five different methods for detecting antibodies to brucella abortus. the sera were tested for brucella spp. antibody activity by the card (card), rivanol precipitation (riv), standard agglutination tube (sat), cold complement fixation test (cf), and enzyme linked immunosorbent assay (elisa) methods. each serum sample selected for this comparison demonstrated ... | 1991 | 1949585 |
| interspecific transmission of brucella abortus from experimentally infected coyotes (canis latrans) to parturient cattle. | in four separate trials, 10 coyotes (canis latrans) which had been individually fed mascerated bovine placental tissue experimentally inoculated with brucella abortus strain 2308 were placed in a 1 ha isolation area with six parturient, non-b. abortus vaccinated, brucella spp. seronegative hereford heifers. during the second trial, three of the heifers became brucella spp. seroreactive (as determined by the card, standard agglutination tube, rivanol, complement fixation, and enzyme labeled immun ... | 1988 | 3137371 |
| serological survey for diseases in free-ranging coyotes (canis latrans) in yellowstone national park, wyoming. | from october 1989 to june 1993, we captured and sampled 110 coyotes (canis latrans) for various diseases in yellowstone national park, wyoming (usa). prevalence of antibodies against canine parvovirus (cpv) was 100% for adults (> 24 months old), 100% for yearlings (12 to 24 months old), and 100% for old pups (4 to 12 months old); 0% of the young pups (< 3 months old) had antibodies against cpv. presence of antibodies against canine distemper virus (cdv) was associated with the age of the coyote, ... | 1997 | 9027690 |
| safety of brucella abortus strain rb51 vaccine in non-target ungulates and coyotes. | brucellosis is endemic in free-ranging elk (cervus elaphus) and bison (bison bison) in the greater yellowstone area (gya; usa). it is possible that an oral brucellosis vaccine could be developed and disseminated in the gya to reduce disease transmission. should this occur, non-target species other than elk and bison may come in contact with the vaccine resulting in morbidity or mortality. to assess biosafety, bighorn sheep (ovis canadensis; n = 10), pronghorn (antilocapra americana; n = 9), mule ... | 2002 | 12238372 |
| parasitology and serology of free-ranging coyotes (canis latrans) in north carolina, usa. | coyotes (canis latrans) have expanded recently into the eastern us and can serve as a source of pathogens to domestic dogs (canis lupus familiaris), livestock, and humans. we examined free-ranging coyotes from central north carolina, us, for selected parasites and prevalence of antibodies against viral and bacterial agents. we detected ticks on most (81%) coyotes, with amblyomma americanum detected on 83% of those with ticks. fifteen (47%) coyotes were positive for heartworms (dirofilaria immiti ... | 2015 | 25984773 |
