with the aim of controlling malaria by reducing vector population, the effects of antibodies produced against salivary glands and deglycosylated midgut antigens of anopheles stephensi mosquitoes on fecundity and longevity of the same species were tested. three deglycosylated preparations of midgut and two preparations of salivary glands were produced, conjugated with aluminum hydroxide gel, and...

ticks are important ectoparasites which are a considerable threat to human beings and to animals all overthe world. enormous economic losses annually occur in livestock production around the world as a result oftheir existance. one of the ways to control ticks and tick-borne diseases is to introduce resistance to theseectoparasites through immunization. for identification of the putative protec...

  Partially fed (4 -5 days) H .a. anatolicum (Iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (GS), gut membrane antigen (GM), triton extracted gut membrane antigen ( TX-GM ) and sodium dodecyl sulphate treated Triton extracted gut membrane antigen (SDS-TX-GM). The New Zealand white rabbits were immunized with GS, GM, TX- ...

Insect galectins are associated with embryonic development or immunity against pathogens. Here, we show that they can be exploited by parasites for survival in their insect hosts. PpGalec, a tandem repeat galectin expressed in the midgut of the sandfly Phlebotomus papatasi, is used by Leishmania major as a receptor for mediating specific binding to the insect midgut, an event crucial for parasi...

Several oral vaccination studies have been undertaken to evoke a better protection against white spot syndrome virus (WSSV), a major shrimp pathogen. Formalin-inactivated virus and WSSV envelope protein VP28 were suggested as candidate vaccine components, but their uptake mechanism upon oral delivery was not elucidated. In this study the fate of these components and of live WSSV, orally intubat...

Malaria parasites must undergo development within mosquitoes to be transmitted to a new host. Antivector transmission-blocking vaccines inhibit parasite development by preventing ookinete interaction with mosquito midgut ligands. Therefore, the discovery of novel midgut antigen targets is paramount. Jacalin (a lectin) inhibits ookinete attachment by masking glycan ligands on midgut epithelial s...

background: many microorganisms in midgut of mosquito challenge with their host and also other pathogens pre­sent in midgut. the aim of this study was presence of non-pathogens microorganisms like fungal flora which may be cru­cial on interaction between vectors and pathogens. } methods: different populations of anopheles stephensi were reared in insectary and objected to determine fungal flora...
