colonization of grande comore island by a lineage of rhipicephalus appendiculatus ticks.union of the comoros suffered a severe east coast fever epidemic in 2004. rhipicephalus appendiculatus was probably involved in pathogen transmission as this competent tick species, although previously absent from comoros, was sampled on 4 animals on one geographical site during the epidemic. we carried out an entomological survey on all three islands of union of the comoros to establish cattle tick species distribution with a special emphasis on r. appendiculatus. we investigated r. appendicula ...201121414194
genetic variation in rhipicephalus appendiculatus (acari: ixodidae) from zambia: correlating genetic and ecological variation with rhipicephalus appendiculatus from eastern and southern africa.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, respectively, genetically compare to stocks from east africa (rwanda) and southern africa (zimbabwe and south africa). the its2 and two mitochon ...200718260504
an outbreak of east coast fever on the comoros: a consequence of the import of immunised cattle from tanzania?in 2003 and 2004, a severe epidemic decimated the cattle population on grand comore, the largest island of the union of comoros. fatalities started soon after the import of cattle from tanzania. theileria parva and its vector, rhipicephalus appendiculatus, could be identified as the main culprits of the epidemic. characterisation by multilocus genotyping revealed that the t. parva parasites isolated on the comoros were identical to the components of the muguga cocktail vaccine used in tanzania t ...200716996692
