Delayed-type hypersensitivity to Phlebotomus papatasi sand fly bite: An adaptive response induced by the fly?

The saliva of bloodsucking arthropods contains a large array of pharmacologically active compounds that assist hematophagy. Arthropod saliva is also responsible for causing uncomfortable allergic responses in its vertebrate hosts. In this article, we investigate whether the sand fly Phlebotomus papatasi, known to produce a strong delayed-type hypersensitivity (DTH) in humans, could benefit from...

Helminths and bot fly larvae of wild ungulates on a game ranch in central province, Zambia.

Helminths and bot fly larvae were collected from 11 wild ungulate species on a game ranch in the Central Province of Zambia. New host-parasite records are: Calicophoron sp. from defassa waterbuck Kobus ellipsiprymnus defassa and Kafue lechwe Kobus leche kafuensis; Avitellina centripunctata, Gaigeria pachyscelis and Gedoelstia cristata from tsessebe Damaliscus lunatus lunatus; Cooperia rotundisp...

Distribution of the Bot Fly Cuterebra emasculator (Diptera: Cuterebridae) in South Carolina1

Larvae of the bot fly Cuterebra emasculator Fitch infest tree squirrels and chipmunks from the Atlantic Ocean to just west of the Mississippi River and from southern Canada to the Gulf Coast of the United States. Whether the species is present in all states and provinces in this region is not well documented. Because there are few published records of C. emasculator in South Carolina, we gather...

Proteolytic activity in salivary gland products of sheep bot fly (Oestrus ovis) larvae.

This study identified and characterized hydrolytic enzymes in salivary gland products of Oestrus ovis larvae. Third instars were collected from the heads of slaughtered goats. Salivary glands were extracted, their products obtained by centrifugation and the enzymatic profile determined. Optimum pH, temperature of maximum proteolytic activity, thermal stability, and resistance of salivary gland ...
