Hyalomma marginatum is a hard-bodied tick found on animals. This tick has been implicated in the transmission of Bahig virus, a pathogenic arbovirus previously thought to be transmitted only by mosquitoes.

Adult females of the blacklegged tick, Ixodes scapularis (Acari: Ixodidae), were collected from a North American porcupine, Erethizon dorsatum, in eastern Ontario, Canada. This porcupine parasitism indicates that an established population I. is present local vicinity. tick species known to parasitize more than 150 different vertebrate hosts, including porcupine. The presence ticks parasitizing ...

The genus Anaplasma (Rickettsiales: Anaplasmataceae) includes obligate tick-transmitted intracellular organisms, Anaplasma phagocytophilum and Anaplasma marginale that multiply in both vertebrate and tick host cells. Recently, we showed that A. marginale affects the expression of tick genes that are involved in tick survival and pathogen infection and multiplication. However, the gene expressio...

this study was conducted during 3 years period (2002-2004). tick sampling was carried out randomly from domestic animals during seasonal activity of ticks from different parts of iran. 2170 ticks from 151 cattle, 629 sheep, 336 goats and 33 camels were collected. the occurance of tick infestation in cattle, sheep, goats and camels was 60%, 71.4%, 53% and 46 % respectively. sampled ticks of rhip...

Ticks require blood meal to complete development and reproduction. Multifunctional tick salivary glands play a pivotal role in tick feeding and transmission of pathogens. Tick salivary molecules injected into the host modulate host defence responses to the benefit of the feeding ticks. To colonize tick organs, tick-borne microorganisms must overcome several barriers, i.e., tick gut membrane, ti...

BACKGROUND Understanding and quantification of the risk of Lyme borreliosis after a tick bite can aid development of prevention strategies against Lyme borreliosis. METHODS We used 3,525 single tick bite reports from three large prospective studies on the transmission risk of tick-borne pathogens to humans, with 50 reports of Lyme borreliosis during the follow-up period, among 1,973 reports w...

Ticks and tick transmitted infectious agents are increasing global public health threats due to abundance, expanding geographic ranges of vectors pathogens, emerging tick-borne agents. Greater understanding tick, host, pathogen interactions will contribute development novel control disease prevention strategies. Tick-borne pathogens adapt in multiple ways very different vertebrate host environm...

Improvements to risk assessments are needed to enhance our understanding of tick-borne disease epidemiology. We review tick vectors and duration of tick attachment required for pathogen transmission for the following pathogens/toxins and diseases: (1) Anaplasma phagocytophilum (anaplasmosis); (2) Babesia microti (babesiosis); (3) Borrelia burgdorferi (Lyme disease); (4) Southern tick-associated...
