Dogs develop resistance to Rhipicephalus sanguineus

Veterinary Parasitology, 1997
The capacity of Beagle dogs to develop resistance against infestation by adult females of Rhipicephalus sanguineus was investigated. The number of successive engorged females recovered from dogs at the second infestation of the tick was significantly less than at the first infestation. However, there were no significant differences in body weight, body

Efficacy of d-Limonene Nanoemulsion Against Rhipicephalus annulatus and Rhipicephalus sanguineus Ticks

Acta Parasitologica, 2023
Ticks infestation has a negative impact against human and animal health through blood sucking, transmission of blood-borne diseases and also caused economic losses.In the present study the adulticidal, ovicidal and larvicidal activity of D-limonene nanoemulsion (DLN) were evaluated against two tick species; Rhipicephalus annulatus and Rhipicephalus ...

Immunological response in rabbits infested with Rhipicephalus sanguineus

Medical and Veterinary Entomology, 1994
Abstract. In order to clarify the importance of humoral antibody in host resistance to ticks, in the present work we studied the immunological response of rabbits infested with larvae, nymphs or adults of Rhipicephalus sanguineus , using extracts of eggs (EE), larvae (LE),

Abnormal development of Rhipicephalus sanguineus (Ixodidae)

Experimental & Applied Acarology, 2001
Three malformed Rhipicephalus sanguineus specimens were noticed in a tick laboratory colony. These specimens had different degrees of twining, from an almost fused individual (with two anal pores) to a partially fused adult male, with four spiracular plates. One female was a heart-shaped specimen.

Histamine blocking agent in the salivary gland homogenate of the tick Rhipicephalus sanguineus sanguineus

Nature, 1977
STUDIES of reactivity to tick bites and tick salivary gland homogenate have revealed responses similar to those induced by histamine in the skin of lop-eared rabbits2. Salivary gland homogenates of the tick Rhipicephalus sanguineus sanguineus, however, did not cause contraction of guinea pig ileum, but blocked the action of histamine acid phosphate ...

Reprolysin metalloproteases from Ixodes persulcatus, Rhipicephalus sanguineus and Rhipicephalus microplus ticks

Experimental and Applied Acarology, 2014
Metalloproteases (MPs) have been considered essential for blood feeding and other physiological functions in several hematophagous animals, including ticks. We report the characterization of MP sequences of three important ticks from Asia, Africa and America: Ixodes persulcatus (Ip-MPs), Rhipicephalus sanguineus (Rs-MPs) and R.

Cold-stress response of engorged females of Rhipicephalus sanguineus

Experimental and Applied Acarology, 2011
We investigated the effect of prolonged exposure to low temperature on engorged females of Rhipicephalus sanguineus. Five groups of two females (F1-F5) were maintained at 8 ± 2°C, 70 ± 10% RH, and 24 h scotophase, for 15, 30, 45, 60 and 75 days. One group was maintained in the incubator (26 ± 1°C, 70 ± 10% RH, and 24 h scotophase) as control.
