BACKGROUND Rickettsioses are one of the most important causes of systemic febrile illness among travelers from developed countries, but little is known about their incidence in indigenous populations, especially in West Africa. METHODOLOGY/PRINCIPAL FINDINGS Overall seroprevalence evaluated by immunofluorescence using six rickettsial antigens (spotted fever and typhus group) in rural populati...

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...

The present study aimed to determine the phenology and predilection sites of ticks infesting cattle in western region Djurdjura (North Algeria) from November 2018 October 2020. Nineteen farms located thirteen localities within four provinces were visited monthly for two years. Among 289 examined cattle, 64.36 ± 2.81% (n=189) infested by ticks. Of 10,243 collected ticks, most abundant tick speci...

Before the eradication of Boophilus ticks from the United States, Rhipicephalus (Boophilus) microplus (Canestrini) and Rhipicephalus (Boophilus) annulatus (Say) were important biological vectors of the cattle pathogen Anaplasma marginale Theiler. In the absence of Boophilus ticks, A. marginale continues to be transmitted by Dermacentor ticks. However, a few U.S. strains are not transmissible by...

Abstract The one-host cattle fever tick, Rhipicephalus (Boophilus) annulatus (Say), and southern microplus (Canestrini), are important ectoparasitic pests of cattle, Bos taurus L., mostly for transmitting the causal agents bovine babesiosis. Bovine babesiosis inflicted substantial production losses in United States before vectors were eliminated by 1943, with exception a Permanent Quarantine Zo...

Species of Rhipicephalus (Boophilus) ticks are the vectors of babesiosis (cattle fever tick), which are distributed worldwide. White-tailed deer (Odocoileus virginianus) are important secondary hosts for the cattle fever ticks, Rhipicephalus (B.) annulatus and Rhipicephalus (B.) microplus. White-tailed deer are capable of sustaining Boophilus spp. tick populations in the presence or absence of ...
