| description | <p>Abstract</p> <p>Background</p> <p><it>Rhipicephalus (Boophilus) microplus </it>is an obligate blood feeder which is host specific to cattle.

Among the 13,601 <it>R. microplus </it>transcripts from BmiGI Version 2 we identified 297 high and 17 low expressed transcripts that were significantly differentially expressed between <it>R. microplus </it>feeding on tick resistant cattle [<it>Bos indicus </it>(Brahman)] compared to <it>R. microplus </it>feeding on tick susceptible cattle [<it>Bos taurus </it>(Holstein-Friesian)] (p ≤ 0.001).
