Molecular detection and characterisation of Theileria parva and other Theileria species in cattle-associated ticks from southern Mozambique

A study investigating tick-borne protozoa in southern Mozambique confirms the presence of Theileria parva, a pathogen responsible for East Coast fever (ECF), in local cattle-associated ticks. Researchers analyzed 326 ticks from six farms, identifying four species: Rhipicephalus microplus, R. evertsi, Amblyomma hebraeum, and R. appendiculatus. Molecular screening detected T. parva in 11 ticks, with phylogenetic analysis revealing low genetic diversity among isolates, except for one divergent isolate found in A. hebraeum. Additionally, Theileria velifera was identified in a single specimen. These findings underscore the need for ongoing surveillance to monitor the spread and impact of these pathogens on cattle production in the region.
