Association of Anaplasma marginale Strain Superinfection with Infection Prevalence within Tropical Regions
Strain superinfection occurs when a second strain infects a host already infected with and having mounted an immune response to a primary strain. The incidence of superinfection with Anaplasma marginale, a tick-borne rickettsial pathogen of domestic and wild ruminants, has been shown to be higher in tropical versus temperate regions. This has been attributed to the higher prevalence of infectio...
متن کاملStochastic transmission of multiple genotypically distinct Anaplasma marginale strains in a herd with high prevalence of Anaplasma infection.
Multiple genotypically unique strains of the tick-borne pathogen Anaplasma marginale occur and are transmitted within regions where the organism is endemic. In this study, we tested the hypothesis that specific A. marginale strains are preferentially transmitted. The study herd of cattle (n = 261) had an infection prevalence of 29% as determined by competitive inhibition enzyme-linked immunosor...
متن کاملTick-borne transmission of two genetically distinct Anaplasma marginale strains following superinfection of the mammalian reservoir host.
Strain superinfection affects the dynamics of epidemiological spread of pathogens through a host population. Superinfection has recently been shown to occur for two genetically distinct strains of the tick-borne pathogen Anaplasma marginale that encode distinctly different surface protein variants. Superinfected animals could serve as a reservoir for onward transmission of both strains if the t...
متن کاملA Canadian bison isolate of Anaplasma marginale (Rickettsiales: Anaplasmataceae) is not transmissible by Dermacentor andersoni (Acari: Ixodidae), whereas ticks from two Canadian D. andersoni populations are competent vectors of a U.S. strain.
Anaplasma marginale Theiler is a tick-borne rickettsial pathogen of cattle with a global distribution in both temperate and tropical regions. The pathogen is endemic in regions within the United States, whereas the Canadian cattle population is considered to be free ofA. marginale. Farmed bison, Bison bison L., in central Saskatchewan have been found to be infected with A. marginale; however, t...
متن کاملSir Arnold Theiler and the discovery of anaplasmosis: a centennial perspective.
Sir Arnold Theiler's research in 1908/09 led to the discovery of the first rickettsial pathogen, Anaplasma marginale, and set the stage for his development and implementation of an effective live vaccine based on a less virulent strain, A. marginale ss. centrale. His 1910 report, describing A. marginale, is among the classic monographs in infectious disease research, presenting not only observa...
