Rhipicephalus(Boophilus) microplus resistant to acaricides and ivermectin in cattle farms of Mexico [PDF]

Revista Brasileira de Parasitologia Veterinária, 2014
Ticks and the diseases they transmit cause great economic losses to livestock in tropical countries. Non-chemical control alternatives include the use of resistant cattle breeds, biological control and vaccines. However, the most widely used method is the application of different chemical classes of acaricides and macrocyclic lactones.

Tick‐borne pathogen interactions enhance transmission in cattle and ticks in Ogun, Nigeria

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Tick‐borne diseases (TBDs) pose a major public health concern in tropical regions, where co‐infections and pathogen interactions complicate disease control. Understanding how these interactions vary across vertebrate hosts and tick vectors, and their impact on disease transmission, is crucial for developing effective intervention strategies ...

CattleTickBase: An integrated Internet-based bioinformatics resource for Rhipicephalus (Boophilus) microplus [PDF]

International Journal for Parasitology, 2012
The Rhipicephalus microplus genome is large and complex in structure, making it difficult to assemble a genome sequence and costly to resource the required bioinformatics. In light of this, a consortium of international collaborators was formed to pool resources to begin sequencing this genome.

A Trypanosoma species detected in Rhipicephalus (Boophilus) microplus ticks from Argentina

Ticks and Tick-borne Diseases, 2021
Specimens of a Trypanosoma sp. were found in a haemolymph sample of Rhipicephalus microplus from Argentina. Polymerase chain reaction (PCR) was done targeting the SSU rRNA gene of Trypanosoma spp. and a fragment of 2300 base pairs (bp) was amplified, subsequently a phylogenetic analysis was conducted, based on an alignment of 905 bp, containing the ...
