Microarray analysis of acaricide-inducible gene expression in the southern cattle tick, 'Rhipicephalus (Boophilus) microplus'

Acaricide-inducible differential gene expression was studied in larvae of 'Rhipicephalus (Boophilus) microplus' using a microarray-based approach. The acaricides used were: coumaphos, permethrin, ivermectin, and amitraz. The microarrays contained over 13 000 probes, having been derived from a previously described R. 'microplus' gene index (BmiGI Version 2; Wang et al., 2007). Relative quantitative reverse transcriptase-PCR, real time PCR, and serial analysis of gene expression data was used to verify microarray data. Among the differentially expressed genes with informative annotation were legumain, glutathione S-transferase, and a putative salivary gland-associated protein.
