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. appendiculatus from the southern and the eastern provinces of Zambia, representing two ecological groups, i.e., southern African and transition groups,

Rhipicephalus appendiculatus: Characterization of a testis-associated protein
Experimental Parasitology, 2008A 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.

Survival of unfed Rhipicephalus appendiculatus and Rhipicephalus zambeziensis adults
Medical and Veterinary Entomology, 2005Abstract. Two ixodid tick species, Rhipicephalus appendiculatus (Neumann) and Rhipicephalus zambeziensis (Walker et al .) (Acari: Ixodidae), both originating from the southern province of ...

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 ...

Diapause induction in adults of three Rhipicephalus appendiculatus stocks
Experimental & Applied Acarology, 1999Newly-moulted adults of three Rhipicephalus appendiculatus stocks, originating from Kenya, Zambia and Zimbabwe, were kept in different photoperiods (12h:12h, 13h:11h and 14h:10h light:dark). The stock originating from Kenya showed almost no behavioural diapause in any of these day lengths, whereas virtually all individuals of the Zimbabwean stock ...

Humoral antibody response of rabbits to Rhipicephalus appendiculatus infestation
Research in Veterinary Science, 1987Rabbits 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 ...

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

Production of Rhipicephalus appendiculatus with High Infections of Theileria parva
The Journal of Parasitology, 1981Theileria 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, 1979Methods 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.
