Immunoglobulin G binding proteins in male Rhipicephalus appendiculatus ticks

open access: yesParasite Immunology, 1995
Three abundant immunoglobulin G binding proteins (IGBPs) of29kDa (IGBP-MA), 25kDa (IGBP-MB), and 21 kDa (IGBP-MC) were isolated from partly fed male Rhipicephalus appendiculatus ticks using an agar-ose-IgG column.

Rhipicephalus appendiculatus: Characterization of a testis-associated protein

Experimental Parasitology, 2008
A novel gene coding for Rhipicephalus appendiculatus Male-specific Protein (RAMP) was identified in a cDNA library constructed from the testis/vas deferens of R. appendiculatus ticks. This gene encodes a secreted protein exclusively expressed in the testis/vas deferens.

Detection of immune response in rabbits infested with Rhipicephalus appendiculatus and Rhipicephalus evertsi evertsi

Research in Veterinary Science, 1987
Two groups of rabbits infested repeatedly with Rhipicephalus evertsi evertsi and R appendiculatus acquired resistance as evidenced by reduced ectoparasite engorged weights and development of anti-tick antibodies in the hosts. The enzyme-linked immunosorbent assay (ELISA) using salivary gland antigens of R appendiculatus was able to detect antibody ...

Species Identification of Rhipicephalus duttoni in Relation to the Rhipicephalus appendiculatus Group (Acarina: Ixodidae)

Journal of Medical Entomology, 1991
Rhipicephalus duttoni Neumann is a common tick species in Angola, where its distribution is sympatric with that of R. zambeziensis Walker. Evidence is presented supporting R. duttoni as a distinct species of the R. appendiculatus group. R. duttoni showed a species-specific glucose phosphate isomerase isoenzyme pattern. The ticks, which are difficult to

Humoral antibody response of rabbits to Rhipicephalus appendiculatus infestation

Research in Veterinary Science, 1987
Rabbits infested four times in succession with adult Rhipicephalus appendiculatus developed anti-tick antibodies, demonstrated by the enzyme-linked immunosorbent assay, following primary infestation and increased by subsequent infestations. Maximum antibody activity was detected after the third infestation while lower ixodid engorged weights occurred ...

Production of Rhipicephalus appendiculatus with High Infections of Theileria parva

The Journal of Parasitology, 1981
Theileria parva, the main protozoan responsible for East Coast fever (ECF) of cattle, is the most important livestock parasite in East and Central Africa. A high priority in ECF research is the development of methods for harvesting large numbers of T. parva sporozoites from the salivary glands of the tick vector, Rhipicephalus appendiculatus.

Artificial infection of the tick Rhipicephalus appendiculatus with Theileria parva

Research in Veterinary Science, 1979
Methods for infecting Rhipicephalus appendiculatus ticks with Theileria parva by injection and by artificial feeding were confirmed and compared. The injection method proved simpler and at best as effective and suggested improvements are described.

Integument and Sensillum Auriforme of the Opisthosoma of Rhipicephalus appendiculatus (Acari: Ixodidae)

Journal of Medical Entomology, 1996
The opisthosomal integument and sensilla auriformia of Rhipicephalus appendiculatus Neumann larvae, nymphs, females and males, both unfed, fed, and during molt, were examined by light and electron microscopy in relation to semiochemical production. The integument consists of epidermis, endocuticle, exocuticle, epicuticle, a superficial wax layer and a ...

Genetic variation in Rhipicephalus appendiculatus (Acari: Ixodidae) from Zambia: correlating genetic and ecological variation with Rhipicephalus appendiculatus from eastern and southern Africa.

open access: yesJournal of Vector Ecology, 2007
Based on their ecology, Rhipicephalus appendiculatus ticks from eastern and southern Africa have been divided into three groups. We investigated how two geographic genetically differentiated stocks of R.
