13. Serum susceptibility of Haemophilus somnus from bovine clinical cases and carriers.
The serum susceptibility of 64 isolates of Haemophilus somnus from cattle was determined in a bactericidal assay with undiluted fresh or inactivated bovine serum with serial dilutions of bacterial suspension in RPMI 1640 medium. A total of 27 strains isolated from cattle with clinical disease (4 with thromboembolic meningoencephalitis, 13 with pneumonia, and

14. Haemophilus somnus Induces Apoptosis in Bovine Endothelial Cells In Vitro
Haemophilus somnus causes pneumonia, reproductive failure, infectious myocarditis, thrombotic meningoencephalitis, and other diseases in cattle. Although vasculitis is commonly seen as a result of systemic H. somnus infections, the pathogenesis of vascular damage is poorly characterized. In this study, we demonstrated that H. somnus (pathogenic isolates 649,

15. Antigenic specificity of convalescent serum from cattle with haemophilus somnus-induced experimental abortion.
The antigens of Haemophilus somnus recognized by convalescent bovine serum were studied by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting with a protein A-peroxidase conjugate. The same two 76K and 40K antigens were predominant in whole-bacterium preparations and in outer-membrane-enriched, Triton X-100-insoluble fractions. Th

16. Distribution of Bovine Herpesvirus Type 5 DNA in the Central Nervous Systems of Latently, Experimentally Infected Calves
Bovine herpesvirus type 5 (BHV-5) is an alphaherpesvirus associated with meningoencephalitis, a disease highly prevalent in South America. In this study, we investigated the distribution of BHV-5 DNA in the brains of latently, experimentally infected calves by using a PCR for the glycoprotein B gene. Twelve calves inoculated intranasally with a Brazilian BHV

17. Characterization of a 78-kilodalton outer membrane protein of Haemophilus somnus.
A 78-kilodalton (kDa) outer membrane protein (OMP) of Haemophilus somnus was one of the two antigens most consistently and most intensely immunoreactive in Western immunoblots of whole cells of H. somnus reacted with convalescent-phase serum obtained from cattle with experimental H. somnus pneumonia. This antigen was isolated by gel filtration chromatography

18. Modification of resistance of mice to Naegleria fowleri infections.
Naegleria fowleri, which produces a fatal meningoencephalitis in humans, is also able to produce a progressive and fatal disease in mice. The course of the disease in DUB/ICR mice is dependent upon the infecting dose of organisms, whether administered intraperitoneally (i.p.) or intravenously (i.v.). All of the mice receiving 10(7) trophozoites/mouse i.v. or
