Tick-borne rickettsial diseases (TBRD) are commonly encountered in medical and veterinary clinical settings. The control of these diseases is difficult, requiring disruption of a complex transmission chain involving a vertebrate host and ticks. The geographical distribution of the diseases is related to distribution of the vector, which is an indicator of risk for the population. A total of 110...
BACKGROUND Crimean-Congo Haemorrhagic Fever Virus (CCHFV) is a zoonotic virus transmitted by Ixodid ticks and causes Crimean-Congo hemorrhagic fever (CCHF) disease in humans with up to 50 % mortality rate. METHODS Freshly slaughtered livestock at the Kumasi abattoir in the Ashanti Region of Ghana were examined for the presence of ticks once a month over a 6-month period from May to November 2...
background: ticks are the main vectors for transmission of different pathogens to human and animals. this survey was performed to find out distribution of ticks, which infested the domestic ruminants in yazd province, central iran during year 2008-2009. methods: a total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. ticks were...

OBJECTIVES: An epidemiologicalstudy was conducted in Semnan area to determine thecurrent situation of tick infestation in sheep and assess theefficacy of usage of CIS-cypermethrin against tick infestationunder field condition. METHODES: Sampling was ...
The prevalence of tick-borne encephalitis virus (TBEV) in southern Korea was determined by collecting ticks using tick drags. A total of 4,077 of 6,788 ticks collected were pooled (649 pools) according to collection site, species, and developmental stage and assayed for TBEV. The TBEV protein E and NS5 gene fragments were detected using RT-nested PCR in six pools of nymphs collected from Jeju I...
background: there is a little data on coxiella burnetii (q fever agent) in iran. ticks may play a significant role in the transmission of c. burnetii among animals . the aim of this study was to use polymerase chain reaction for the detection of c. burnetii in ticks collected in southeast iran. methods : one hundred and sixty ticks were collected from domestic animals in three localities of ke...
