Project description:Transcriptional profiling of midgut tissues isolated from Rhipicephalus microplus and Rhipicephalus decoloratus females at day 20 post infestation. This enabled the identification of transcripts that are species-specific or shared between the two tick species tested.
Project description:Organophosphate resistant and susceptible tick larvae from laboratory strains of the southern cattle tick, Rhipicephalus (Boophilus) microplus were exposed to low doses of the organophosphate (OP) acaricide, coumaphos. Serial Analysis of Gene Expression (SAGE) was used to analyze differential gene expression in response to OP treatment and to compare the responses in OP-treated and untreated resistant and susceptible tick larvae. ** note: Contact person is Felix D.
