Open Access | Co-infections of Plasmodium knowlesi, P. falciparum, and P. vivax among Humans and Anopheles dirus Mosquitoes, Southern Vietnam

These results imply that even if human malaria could be eliminated, forests that harbor An. dirus mosquitoes and macaque monkeys will remain a reservoir for the zoonotic transmission of P. knowlesi.

Open Access | Short Report: Improvement of the observational method for Plasmodium berghei oocysts in the midgut of mosquitoes

To evaluate the accuracy in the oocyst counting with the improved technique, mosquitoes were infected with the green fluorescent protein (GFP)-expressing parasite.

Identification and characterization of a novel chitinase-like gene cluster (AgCht5) possibly derived from tandem duplications in the African malaria mosquito, Anopheles gambiae

Insect chitinase 5 (Cht5), a well-characterized enzyme found in the molting fluid and/or integument, is classified as a group I chitinase and is usually encoded by a single gene.

Identification and distribution of a GABA receptor mutation conferring dieldrin resistance in the malaria vector Anopheles funestus in Africa

The distribution of the RdlR mutation in An. funestus populations in Africa suggests extensive barriers to gene flow between populations from different regions.

Open Access | Alternative splicing of the Anopheles gambiae Dscam gene in diverse Plasmodium falciparum infections

Smith PH, Mwangi JM, Afrane YA, Yan G, Obbard DJ, Ranford-Cartwright LC, Little TJ
Reference:

While the data clearly indicate that AgDscam diversity increases with P. falciparum exposure, they do not suggest that AgDscam diversity rises further in response to increased parasite diversity.

Open Access | Biochemical Comparison of Anopheles gambiae and Human NADPH P450 Reductases Reveals Different 2′-5′-ADP and FMN Binding Traits

PLoS ONE 6(5): e20574

NADPH-cytochrome P450 oxidoreductase (CPR) plays a central role in chemical detoxification and insecticide resistance in Anopheles gambiae, the major vector for malaria.

Entomological Study on Transmission of Avian Malaria Parasites in a Zoological Garden in Japan: Bloodmeal Identification and Detection of Avian Malaria Parasite DNA from Blood-Fed Mosquitoes

Larvicidal activity of synthesized silver nanoparticles using Eclipta prostrata leaf extract against filariasis and malaria vectors

Mosquitoes transmit serious human diseases, causing millions of deaths every year. Use of synthetic insecticides to control vector mosquitoes has caused physiological resistance and adverse environmental effects in addition to high operational cost.

Open Access | Daily Plasmodium yoelii infective mosquito bites do not generate protection or suppress previous immunity against the liver stage

Tzvi Pollock, Ricardo Leitao, Cristina Galan-Rodriguez, Kurt A Wong, Ana Rodriguez

Malaria Journal 2011, 10:97 (18 April 2011)

Liver stage immunity generated by irradiated versus normal P. yoelii infected mosquitoes is essentially different, probably because of the blood stage infection that follows normal mosquito bites, but not irradiated.
