Landscape of exposure: Metapopulation dynamics and local environment structure pathogen exposure in desert bighorn sheep

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Dynamics of infectious disease in natural populations result from processes across scales, from host characteristics shaping exposure risk and susceptibility, to local environmental conditions driving vector populations, to the structure of metapopulation networks shaping transmission of pathogens across the landscape.

Genetic diversity of Anaplasma marginale in Argentina

Veterinary Parasitology, 2009
Bovine anaplasmosis caused by Anaplasma marginale is a worldwide major constraint to cattle production. The A. marginale major surface protein 1 alpha (msp1alpha) gene contains a variable number of tandem repeats in the amino terminal region and has been used for the characterization of pathogen genetic diversity.

Epidemiology of Ticks and Tick‐Borne Hemopathogens of Cattle in Two Selected Districts of Northwest Ethiopia

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
The overall prevalence of tick infestation and tick‐borne haemopathogens of cattle in the study area was 87.8% and 17.1%, respectively. Five species of ticks under three genera were detected; namely: Amblyomma variegatum, Amblyomma lepidum, Rhipicephalus evertsi, Hyalomma rufipes and Rhipicephalus decoloratus were identified.
