b a ckground: a survey on tick species composition was carried out in golestan province iran during year 2010–2011.the aim was to determine tick species parasitizing domestic ruminants and their seasonal population dynamics. methods: a total of 124 sheep, 92 goats, 84 cattle, 74 camels and 12 horses in several villages were inspected for tick infestation. the collected ticks preserved in 70% al...

This study evaluated a recombinant aquaporin 1 protein of Rhipicephalus (Boophilus) microplus (RmAQP1) as antigen in a vaccine against R. sanguineus. Five dogs were immunized with RmAQP1 (10 µg) + adjuvant (Montanide) (G1), and five were inoculated with adjuvant only (G2), three times. Twenty-one days after the last immunization, animals of both groups were challenged with R. sanguineus larvae,...

The brown dog tick (Rhipicephalus sanguineus lato sensu) is the that most affects dogs worldwide and therefore main blood pathogen vector in dogs. efficacy of afoxolaner 2.7 to 7.1 mg/kg NexGard® (group A) plus milbemycin oxime 2.5 5.4 0.5 1.1 respectively NexGard Spectra® (Group B) against R. sanguineus, was evaluated naturally infected sheltered under high challenging conditions four differen...

Effects of water flooding on the oviposition capacity of engorged adult females and hatchability of eggs of Rhipicephalus sanguineus and Haemaphysalis leachi leachi under laboratory conditions were investigated. The durations of time of water flooding were 1, 2, 4, 6, 12, 24, 48, 72, 96, and 120 hours. Engorged females of R. sanguineus and H. leachi leachi did not oviposit after being flooded f...

Blood specimens from clinically normal military dogs and their trainers, in Lara, Venezuela were screened for Anaplasma platys, A. phagocytophilum, or Ehrlichia ewingii using 16S rRNA PCR tests. Sixteen percent (7/ 43) of dog specimens were positive by A. platys PCR test followed by sequencing of the PCR products, and all human blood specimens [25] were negative. All specimens from these dogs a...

It was shown in this study that Rhipicephalus evertsi evertsi males emit pheromones in the preparasitic as well as in the parasitic phases. Conspecific unengorged male and female images exhibited a high response to water-soluble volatiles collected from unengorged males. A vigorous assembly of unfed female R. evertsi evertsi occurred on filter paper discs which had been in contact with either u...

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...
