The control of tick species that affect animal production is vital for the economic welfare of the cattle industry. This study focused on testing the acaricidal activity of the essential oil from the leaves and stems of Tagetes minuta against several Brazilian tick species, including Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, Amblyomma cajennense and Argas miniatus. The chem...

We have identified for the first time Rickettsia africae, and the ticks that harbored them, in Kenya. A total of 5,325 ticks were collected from vegetation, livestock, and wild animals during two field trips to southwestern Kenya. Most were immature forms (85.2%) belonging to the genera Amblyomma or Rhipicephalus. The adults also included representatives from the genus Boophilus. Ticks were ass...

The cattle industry is one of the most important agroeconomic activities in Mexico. The national herd is estimated to include approximately 33.5. million head of cattle. Ticks and tick-borne diseases are principal factors with a negative impact on cattle health and production. The most economically important tick species parasitizing cattle in Mexico are Rhipicephalus microplus, R. annulatus, a...

A total of 200 whole blood samples along with thin blood samples smears and 100 samples of ticks from 20 flocks of sheep from different localities of district Lahore with a history of tick infestation , relapse of fever and anemia were screened for the prevalence of Theileria species during spring and summer seasons in 2007. On microscopic examination 44/200 (22%) samples were positive for Thei...

Ticks were collected at irregular intervals from December 1995 to November 1996 from wildlife on Mtendere Game Ranch in the Chisamba District of Central Province, Zambia. Total collections were made from two species of ground-nesting birds and 20 species of small and large mammals. Thirteen species/subspecies of ixodid ticks were recovered. Rhipicephalus appendiculatus was the most abundant, fo...

ticks are considered to be the main vectors for transmission of various diseases to animals and human. the present faunistic study aimed to determine species belonging to Ixodidae ticks, infesting cattle of Khoozestan province, south-west of Iran. Totally 1000 ticks were collected randomly from cattle from 9 locations in five geographical regions between January to September 2011, and were iden...

This study evaluated a recombinant aquaporin 1 protein of Rhipicephalus (Boophilus) microplus (RmAQP1) as antigen in a vaccine against R. sanguineus. Five dogs were immunized with RmAQP1 (10 µg) + adjuvant (Montanide) (G1), and five were inoculated with adjuvant only (G2), three times. Twenty-one days after the last immunization, animals of both groups were challenged with R. sanguineus larvae,...
