Malaria Infected Mosquitoes Attracted to Human Odor

May 17, 2013 By Malaria.com Leave a Comment

Abstract There is much evidence that some pathogens manipulate the behaviour of their mosquito hosts to enhance pathogen transmission. However, it is unknown whether this phenomenon exists in the interaction of Anopheles gambiae sensu stricto with the malaria parasite, Plasmodium falciparum - one of the most important interactions in the context of humanity, with malaria causing over 200 … [Read more...]

How Mosquito Immune System Attacks Specific Infections, Including Malaria Parasite

October 18, 2012 By Malaria.com Leave a Comment

Researchers have determined a new mechanism by which the mosquitoes’ immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene. Unlike humans and other animals, insects do not make antibodies to target specific infections. According to researchers at the Johns Hopkins Bloomberg School of Public … [Read more...]

Researchers Discover Proteins in Mosquitoes that Help Fight Malaria Infection

June 6, 2012 By Malaria.com Leave a Comment

Researchers have discovered the function of a series proteins within the mosquito that transduce a signal that enables the mosquito to fight off infection from the parasite that causes malaria in humans. Together, these proteins are known as immune deficiency (Imd) pathway signal transducing factors, are analogous to an electrical circuit. As each factor is switched on or off it triggers or … [Read more...]

Mosquito Immune System Can Be Engineered to Block Malaria

December 22, 2011 By Malaria.com Leave a Comment

Researchers have demonstrated for the first time that the Anopheles mosquito’s innate immune system could be genetically engineered to block the transmission of the malaria-causing parasite to humans. In addition, they showed that the genetic modification had little impact on the mosquito’s fitness under laboratory conditions. “The immune system of the Anopheles mosquito is capable of killing a … [Read more...]

Researchers Discover Microbe That Could Help Fight Malaria

May 13, 2011 By Malaria.com Leave a Comment

Researchers have discovered a bacterium in the gut of the Anopheles mosquito which may someday be used to destroy and, therefore, prevent the spread of the disease-causing parasite. The World Health Organization estimates 800,000 people die of malaria each year. The parasite that causes the disease is transmitted by the Anopheles mosquito. After the mosquito feeds on the blood of an … [Read more...]
