Histopilus somnus in cattle
نویسندگان
چکیده
Histophilosis is a bacterial disease of cattle found worldwide. It presents with clinical syndromes that include pneumonia, meningoencephalitis, myocarditis and arthritis. Collectively these presentations are referred to as the Histophilus somni disease complex (1). Cases can present showing a single or combination of these syndromes. Since first reported in North America in 1956 the incidence of the various syndromes has changed in North America (2). There have been no Australian reports of a similar change in the incidence of presenting syndromes.

Evaluation of the RapID NH system for identification of Haemophilus somnus, Pasteurella multocida, Pasteurella haemolytica, and Actinobacillus pleuropneumoniae isolated from cattle and pigs with respiratory disease.
Haemophilus somnus, Pasteurella haemolytica, Pasteurella multocida, and Actinobacillus pleuropneumoniae from cattle and pigs with respiratory disease were used to evaluate the RapID NH system (Innovative Diagnostics, Atlanta, Ga.). Minor modifications of the RapID NH system to include animal source and growth requirements would permit the identification of all isolates tested.
متن کاملSpecific antibody to Haemophilus somnus in the bovine uterus following intramuscular immunization.
Sources of anti-Haemophilus somnus antibody in bovine uterine secretions following intramuscular immunization and subsequent intrauterine inoculation of killed H. somnus were investigated. Holstein cattle (n = 21) were immunized with a 270-kDa outer membrane protein from H. somnus (omp-270) by intramuscular injection. At estrus, the cattle were given an intrauterine inoculum of a heat-killed su...
متن کاملViable "Haemophilus somnus" induces myosin light-chain kinase-dependent decrease in brain endothelial cell monolayer resistance.
"Haemophilus somnus" causes thrombotic meningoencephalitis in cattle. Our laboratory has previously reported that H. somnus has the ability to adhere to, but not invade, bovine brain endothelial cells (BBEC) in vitro. The goal of this study was to determine if H. somnus alters brain endothelial cell monolayer integrity in vitro, in a manner that would be expected to contribute to inflammation o...
متن کاملProtective ability of antibodies against 78- and 40-kilodalton outer membrane antigens of Haemophilus somnus.
The ability of concentrated antibody against the 78- or 40-kilodalton (kDa) outer membrane protein (OMP) of Haemophilus somnus to passively protect calves against H. somnus-induced pneumonia was determined. The 78- and 40-kDa OMPs were evaluated in passive protection experiments, because results of previous studies demonstrated their (i) immunogenicity for cattle, (ii) intense reactivity with c...
