Development and validation of a PCR-RFLP test to identify African Rhipicephalus (Boophilus) ticks.
The cattle tick Rhipicephalus (Boophilus) microplus has recently invaded West Africa and caused anxiety amongst farmers in Ivory Coast, as livestock production was severely affected. The introduction of this tick species has remained unnoticed for several years, as all the members of this genus are very similar in appearance. To overcome the cumbersome morphological identification of the four closely related R. (Boophilus) spp. in the region, a PCR-RFLP test, based on a part of the second internal transcribed spacer ribosomal DNA (ITS2), was developed. The molecular tool was successfully validated with a large number of ticks recently collected from West Africa and that were identified both morphologically and genetically. The tool developed is simple, fast, reliable and reproducible; hence it can be routinely applied for species identification.
