In the study performed here, not only were cyp genes shown to be constitutively highly expressed in the resistant BSI isolate, but the comparative analysis of ABC superfamily member transcripts in L4 also revealed elevated levels of Hco-abch-1, Hco-ced-7a, Hco-wht-4, Hco-wht-8, Hco-cft-1, and Hco-pgp-9.1 in the resistant BSI isolate compared to the susceptible isolate. Here, PPIG is linked to bathing suit ichthyosis.
