Association of midgut defensin with a novel serine protease in the blood-sucking fly Stomoxys calcitrans.

Midgut-specific immune molecules are produced by the blood-sucking insect Stomoxys calcitrans.

We have cloned and sequenced two defensins, Smd1 and Smd2, from anterior midgut tissue of the blood-sucking fly Stomoxys calcitrans. The DNA and N-terminal protein sequences suggest both are produced as prepropeptides. Smd1 differs from the classic defensin pattern in having an unusual six-amino acid-long N-terminal sequence. Both Smd1 and Smd2 have lower pI points and charge than insect defens...

Epithelial innate immunity. A novel antimicrobial peptide with antiparasitic activity in the blood-sucking insect Stomoxys calcitrans.

The gut epithelium is an essential interface in insects that transmit parasites. We investigated the role that local innate immunity might have on vector competence, taking Stomoxys calcitrans as a model. S. calcitrans is sympatric with tsetse flies, feeds on many of the same vertebrate hosts, and is thus regularly exposed to the trypanosomes that cause African sleeping sickness and nagana. Des...

Stomoxys calcitrans has spread throughout the world and can be found anywhere food and weather conditions are desired. This is the first report of fly biting in Iran caused by Stomoxys calcitrans in Ravand, West of Kashan, central of Iran. Based on our survey, traditional home aviary in the garden courtyard was the development and breeding place of these flies. These flies can painfuly bit duri...
