This study was performed in Maranhão state, a transition area two Brazilian biomes, Amazon and Cerrado. During 2011-2013, 1,560 domestic dogs were sampled for collection of serum blood samples and ticks in eight counties (3 within the Amazon and 5 within the Cerrado). A total of 959 ticks were collected on 150 dogs (9.6%). Rhipicephalus sanguineus sensu lato (s.l.) was the most abundant tick (6...

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 Kerma...

Ticks were collected from vegetation and animals at monthly intervals during one year (1993-1994) in an endemic area of Brazilian spotted fever in the Country of Pedreira, State of São Paulo. Six species of ticks were identified Amblyomma cajennense, Amblyomma cooperi, Amblyomma triste, Anocentor nitens, Rhipicephalus sanguineus and Boophilus microplus. Only the first species was sufficiently n...

The material studied consisted of laboratory-bred specimens of 2 species of Prostriata and 8 species of Metastriata. Jxodes ricinus and / . hexagonus (Prostriata) have XX:XY sex-determining mechanisms with diploid complements of 28 and 26 acrocentric chromosomes respectively. All the species of Metastriata studied have XX:XO sex-determining mechanisms with diploid complements of 21 and 22 chrom...

Serological tests were performed to investigate extent of tick-borne diseases in dogs infested with Rhipicephalus sanguineus at a kennel in Okayama Prefecture. Three of 22 dogs (13.6%) were positive for Ehrlichia canis. Two of 19 dogs (10.5%) were positive for Rickettsia japonica. Three of 22 dogs (13.6%) were positive for Babesia gibsoni. None of these animals were positive for Coxiella burnet...

Ticks are well known as hematophagous ectoparasites, which cause different diseases in humans and animals. This investigation was designed central Iran to assess the prevalence, intensity, abundance of tick infestation stray dogs detection Ehrlichia canis. Overall, 962 ticks were collected from 260 between April August 2018. DNA samples with goal amplification pathogen screened by real-time PCR...

BACKGROUND Rhipicephalus sanguineus and Hyalomma marginatum are the most common species in sheep herds in Northeast of Iran. There is preliminary evidence that these species may be the vectors of Babesia ovis in Iran. We carried out two experiments in Mashhad area, Khorasan Razavi Province to determine whether B. ovis could be transovarially transmitted by R. sanguineus and H. marginatum. MET...
