Effects of aggregation on the reproductive biology of Rhipicephalus sanguineus females [PDF]
Experimental and Applied Acarology, 2011 The brown dog tick Rhipicephalus sanguineus is one of the most important tick species in both veterinary and human medicine. Studies on the biology of this tick are pivotal in order to develop improved control strategies. The brown dog tick is a gregarious species, tending to form large clusters in highly infested environments.

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 ...

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.

Effect of egg clustering on the fitness of Rhipicephalus sanguineus larvae
Parasitology Research, 2012Several biological aspects of Rhipicephalus sanguineus have been studied, but scant information is available on the effect of egg clustering on incubation period and larval survival. Herein, R. sanguineus eggs were separated in groups composed by 1 (GI), 10 (GII), 50 (GIII), 100 (GIV), 500 (GV) and 1,000 (GVI) eggs (10 replicates), and incubation and ...

Comparative Profiling of MicroRNAs in Male and Female Rhipicephalus sanguineus
Applied Biochemistry and Biotechnology, 2015Rhipicephalus sanguineus is an ectoparasite of medical and veterinary significance, which can transmit a number of pathogens including Babesia canis, Ehrlichia canis, and Rickettsia conorii. MicroRNAs (miRNAs) are recognized as regulators in sex differentiation in dioecious species.

Rhipicephalus sanguineus: Sequential histopathology at the host-arthropod interface
Experimental Parasitology, 1974Abstract The reaction beneath the mouth parts of an adult, female Rhipicephalus sanguineus attached to a dog develops progressively over 4–5 days. The cement substance is confined to the external surface of the epidermis and does not form any organized structure in the dermis. The hypostome is imbedded in the cement substance and does not penetrate

Intracutaneous injection of histamine acid phosphate (HAP) and salivary gland extract (SGE) of Haemaphysalis spinigera and Rhipicephalus sanguineus sanguineus into sensitized and nonsensitized rabbits previously injected intravenously with Evans blue indicated that the ticks' saliva contained a pharmacodynamic substance in addition to having antigenic ...
