IgG4 autoimmune diseases are characterized by the presence of antigen-specific autoantibodies of the IgG4 subclass and contain well-characterized diseases such as muscle-specific kinase myasthenia gravis, pemphigus, and thrombotic thrombocytopenic purpura. In recent years, several new diseases were identified, and by now 14 antigens targeted by IgG4 autoantibodies have been described. The IgG4 ...
Pathogenicity of Rickettsia tsutsugamushi for laboratory mice is known to be influenced by at least three factors: (i) route of inoculation, (ii) antigenic strain, and (iii) natural resistance of the host. By using Karp, Gilliam, and Kato strains of R. tsutsugamushi, we examined the effect of these three pathogenicity factors on the kinetics of infection and the development of immunity in BALB/...
Lagos bat virus (LBV) constitutes genotype (gt) 2 in the Lyssavirus genus. In contrast to the gt1 lyssavirus, rabies virus (RABV), LBV was reported to have markedly reduced levels of peripheral pathogenicity. However, this opinion was based on a study of one isolate of LBV only and the reduction in pathogenicity was essentially attributed to the amino-acid substitution at position 333 of glycop...
Various strains of E. coli. and Salmonella typhimurium were studied in vitro for the presence plasmids controlling haemolysin, drug resistance, serum resistance colonization factor etc. They also tested mice to determine probable role on host pathogenicity. To effect associated R-factor pathogenicity virulence S. typhimurium, antibiotic sensitive resistant mice. The experiments showed that enha...
