We conducted a survey of rodents and ticks in Brazos County in east-central Texas to learn more about native fauna that may be involved in enzootic transmission of pathogens that can cause tick-borne diseases in this region. Our objectives were to describe the species richness and seasonal activity of rodents, as well as to document their infestation with ticks over time. We captured 5 rodent s...

The authors discuss the evaluation of the economic impacts of endemic livestock diseases, and economic issues in control of these diseases. Particular attention is focused on helminths and on endemic vector-transmitted infections (particularly ticks and tick-borne diseases). Decisions relating to disease control have to be made by government and by the producer. Government requires information ...

Identifying Borrelia burgdorferi as the causative agent of Lyme disease in 1981 was a watershed moment in understanding the major impact that tick-borne zoonoses can have on public health worldwide, particularly in Europe and the USA. The medical importance of tick-borne diseases has long since been acknowledged, yet little is known regarding the occurrence of emerging tick-borne pathogens such...

Many infectious diseases are zoonoses, that is, they can be transmitted between vertebrate animals and humans. More than a fifth of zoonotic pathogens are transferred from one host to another by vectors, which are often blood-sucking arthropods, such as ticks. In Europe, Lyme borreliosis, spread by Ixodes ricinus tick, is the most prevalent tick-borne zoonosis. I. ricinus spreads also other zoo...

Hyalomma scupense (syn. Hyalomma detritum) is a two-host domestic endophilic tick of cattle and secondarily other ungulates in the Maghreb region (Africa). This species transmits several pathogens, among which two are major livestock diseases: Theileria annulata and Theileria equi. Various other pathogens are also transmitted by this tick species, such as Anaplasma phagocytophilum and Ehrlichia...

Birds, particularly passerines, can be parasitized by Ixodid ticks, which may be infected with tick-borne pathogens, like Borrelia spp., Babesia spp., Anaplasma, Rickettsia/Coxiella, and tick-borne encephalitis virus. The prevalence of ticks on birds varies over years, season, locality and different bird species. The prevalence of ticks on different species depends mainly on the degree of feedi...

Birds transport ticks into Canada during northward spring migration, and some of these are infected with tick-borne zoonotic pathogens. Some Amblyomma species harbour pathogens that cause debilitating diseases can be fatal to humans, domestic wildlife animals. At least 65 spp. indigenous in the Western Hemisphere, approximately half bite humans. longirostre carries Rickettsia amblyommatis which...
