| [production and study of the immunogenic properties of a bivalent inactivated vaccine against mucosal disease (bovine viral diarrhea and infectious rhinotracheitis)]. | bivalent inactivated vaccine against mucous disease (md) and infectious rhinotracheitis (ir) in cattle was produced from cell cultural md and ir virus suspensions. the vaccine was concentrated on aluminium hydroxide, inactivated by ethanol and is without residual virus. saponine in final 1:1500 dilution is added as supplementary adjuvant. immunogeneity of the vaccine was tested on 10-month-old calves, which had shown full resistance against experimental infection with virulent strains of both vi ... | 1979 | 232586 |

| leukocyte changes and interferon production in calves injected with hydrocortisone and infected with infectious bovine rhinotracheitis virus. | correlations between leukocyte counts and serum interferon titers were determined in calves given hydrocortisone (hc) and infectious bovine rhinotracheitis (ibr) virus. calves were injected with either 1 mg or 3 mg of hc/kg of body weight every 8 hours for a total of 9 injections each. control calves were given placebo injections. viral inoculation was given iv 10 hours after the 1st dose of hc or placebo was given. by the time of viral inoculation, all calves injected with hc had developed neut ... | 1979 | 380418 |
| prevalence of bovine virus diarrhoea and infectious bovine rhinotracheitis antibodies in nigerian sheep and goats. | neutralising antibodies to bovine virus diarrhoea virus were commoner in nigerian sheep than goats while precipitating antibodies offered an alternative but less reliable indicator of previous infection. in contrast, neutralising antibodies to infectious bovine rhinotracheitis virus were more common in goats than sheep. these findings are discussed in relation to infectivity rates in cattle and general husbandry practices. | 1977 | 410130 |

| neural changes in recurrent genital infection of infectious bovine rhinotracheitis virus in calves treated with dexamethasone. | recurrent genital infection with infectious bovine rhinotracheitis (ibr) virus was induced in calves by dexamethasone (dm) treatment 3 months after primary infection. the virus was first recovered from vaginal secretions on the 3rd day after the initiation of dm treatment; however, the virus was not recovered at all from nasal secretions or from the cerebrospinal fluid of the dm-treated calves. the significant neural changes in all recurrent infected calves were nonsuppurative poliomyelitis in t ... | 1979 | 444414 |

| a bovine herpesvirus isolated from sheep. | a viral agent was isolated from the trachea of a lamb that was suffering from a respiratory disorder. the physical and chemical properties of the isolates are characteristic of the herpesvirus group. it contains dna in its virion, is ether sensitive, acid labile at ph 3.0 and heat labile at 56 degrees c after five minutes. the cytopathology observed provided further evidence of a herpesvirus isolate. the neutralization of the infectivity of the isolate with antiserum to bovine herpesvirus 1 is e ... | 1978 | 647461 |

| some lesions observed in calves born to cows exposed to the virus of infectious bovine rhinotracheitis in the last trimester of gestation. | sixteen pregnant cows were challenged with infectious bovine rhinotracheitis virus intranasally. one had a mummified fetus, four aborted, one calf was stillborn, two live fetuses were taken at the abattoir and eight calves were born alive. of the eight born alive, five were dead by 12 days of age. four of these had the usual lesions of infectious bovine rhinotracheitis as well as lesions in the intestine and peritoneum and two of the four had a fibrinous pneumonia thought to be caused by aspirat ... | 1978 | 743599 |
| shipping fever pneumonia in yearling feedlot cattle. | during each week of 1974, we surveyed, for illnesses and deaths, a continually changing population of yearling feedlot cattle that, for the year, totaled 407,000 animals. about 5.1% of the cattle sickened and, of these, 18.9% died. from the 3,943 fatalities, 1,988 necropsies were made. about 75% of the clinical diagnoses and 64% of the necropsy diagnoses were respiratory tract diseases; of the fatalities from respiratory tract diseases, 75% were attributed to shipping fever pneumonia. nearly 72% ... | 1976 | 783102 |
| pathological and microbiological observations made on spontaneous cases of acute neonatal calf diarrhea. | the purpose of this report is to describe clinical signs, gross and microscopic lesions, bacteriological and immunofluorescence observations made on spontaneous cases of acute neonatal calf diarrhea (ncd) in dairy and beef herds. the following diagnostic tools were used: 1) direct smears of intestinal content, 2) escherichia coli counts, 3) aerobic bacterial cultures of the small intestine and other organs (the o serogroup and the enterotoxigenicity of the e. coli isolated was determined), 4) de ... | 1976 | 793692 |
| mycoplasma agalactiae subsp. bovis in pneumonia and arthritis of the bovine. | the pneumonic lungs of 42 cattle from 26 feedlots were examined for the presence of mycoplasma, pathogenic bacteria and viruses. four animals representative of two lots failed to yield mycoplasma. one of these yielded the virus of infectious bovine rhinotracheitis and pasteurella hemolytica, the other yielded only p. p. multocida. nine animals in eight lots yielded mycoplasma sp.: five of these were m. bovirhinis, two were m. arginini and two were untypable. all of these animals yielded one or m ... | 1977 | 832194 |
