Male-enriched transcription of genes encoding ASPs and Kunitz-type protease inhibitors in Ancylostoma species.

Various transcripts coding for proteins considered to be central to parasite-host interactions were identified previously as male-enriched in the hookworm Ancylostoma braziliense. Among these genes were an ASP-5-like homologue and a Kunitz-type protease inhibitor. The present study extends this previous work to investigate similar molecules in other hookworms (Ancylostomatidae).

Identification of gender-regulated genes in Ancylostoma braziliense by real-time RT-PCR.

Ancylostoma braziliense belongs to the family Ancylostomatidae and infects cats and dogs in various parts of the tropical world. It is also a zoonotic parasite causing cutaneous larva migrants in humans. There are very few, either biological or molecular, studies of this species.
