Ticks are able to transmit tick-borne infectious agents to vertebrate hosts which cause major constraints to public and livestock health. The costs associated with mortality, relapse, treatments, and decreased production yields are economically significant. Ticks adapted to a hematophagous existence after the vertebrate hemostatic system evolved into a multi-layered defense system against forei...

BACKGROUND Rhipicephalus (Boophilus) annulatus tick is one of the most important ectoparasite of cattle. Recently, several laboratories in the world have been concentrated on immunizing cattle against tick using various types of tissue extracts of ticks. The aim of this study was to evaluate the effect of immunization of cattle with tick salivary gland extract on biological parameters of ticks ...

Anaplasma phagocytophilum (A. phagocytophilum) is the aetiological agent of tick-borne fever in cattle and sheep, granulocytic anaplasmosis human dogs. Livestock, companion animal infections with A. have been reported globally. Across England Wales, two isolates (called ecotypes) ticks. This study examined present livestock wildlife Great Britain (GB), a particular focus on cattle. Clinical sub...

Eight cattle immunized with cattle-derived Theileria parva Boleni stabilate together with six susceptible controls were released in Dombawera Game Park on the Highveld of Zimbabwe. This coincided with Rhipicephalus appendiculatus nymphal activity. The cattle grazed together with African buffaloes (Syncerus caffer) and were not treated against tick infestation. The nymphal tick infestation was h...

Background and Objective: Hard ticks (Acari: Ixodidae) are one of the most important obligate ectoparasites of vertebrates, belonging to class Arachnida, which transmit a wide range of pathological agents such as viruses, bacteria, and parasites to humans and animals in Iran and around the world. Identifying the distribution of hard ticks in a region is important to monitor their control progra...

BACKGROUND Babesiosis is a haemoparasitic disease of domestic and wild animals caused by species of the genus Babesia. Babesia bigemina, B. bovis and B. divergens are known to be pathogenic in cattle. The disease is transmitted during blood feeding by infected ticks and is the most economically important tick-borne disease in tropical and subtropical areas. Ixodid ticks are vectors in the trans...

When Hereford heifers infested with Boophilus annulatus (Say) were treated with a single Ivomec SR Bolus, the concentration of ivermectin in the serum of the treated cattle reached a maximum of 8.8 +/- 0.9 ppb at 2 wk posttreatment. The single bolus treatment resulted in 84.4% control of standard engorging B. annulatus females on treated cattle over the 20-wk trial. Although fewer engorged tick...

Corridor disease, transmitted by the brown ear tick (Rhipicephalus appendiculatus), is one of Africa's most pathogenic tick-borne diseases for cattle. With a focus on this species, we investigated the community parameters (richness, diversity and abundance) of ticks in the Eastern Cape, South Africa, and how this may be linked to the increasing wildlife/cattle interface in the region. There wer...

INTRODUCTION Like all living things, cattle ticks have the ability to overcome adversity in order to survive. They can adapt genetically over time so that they and their offspring build up resistance to the normal tick treatments used. This is known as tick acaricide (chemical) resistance. The prolonged or incorrect use of tick chemicals can lead to resistance in ticks, enabling the ticks to to...

Abstract Potential reinvasion of the United States by cattle fever ticks, Rhipicephalus (Boophilus) annulatus (Say) and R. (B.) microplus (Canestrini), which are endemic in Mexico, threatens domestic livestock industry because these ticks vector causal agents (Babesia bovis (Babes) (Piroplasmida: Babesidae) B. bigemina Smith & Kilborne) bovine babesiosis. The Cattle Fever Tick Eradication P...
