Abstract Background Ecological factors play an important role in the evolution of parasite exploitation strategies. A common prediction is that, as shorter host life span reduces future opportunities...

Abstract Background Intra-specific variation in sperm length influences male reproductive success in several species of insects. In males of the malaria vector Anopheles gambiae , sperm length is...

Abstract Background In female mosquitoes that transmit malaria, the benefits of being refractory to the Plasmodium parasite are balanced by the immunity costs in the absence of infection. Male...

Abstract Background For Anopheline mosquitoes, the vectors of human malaria, genetic variation in male reproductive success can have important consequences for any control strategy based on the...

Abstract Background Genetic linkage mapping identified a region of chromosome 2L in the Anopheles gambiae genome that exerts major control over natural infection by Plasmodium falciparum . This 2L...

We investigated patterns of genetic diversity of Plasmodium falciparum associated with its two main African vectors: Anopheles gambiae and Anopheles funestus. We dissected 10,296 wild-caught...

Malaria Infection Increases Attractiveness of Humans to Mosquitoes (2005)

A study of children in Kenya reveals that those individuals harboring the transmissible gametocyte stage of malaria parasites are more attractive to the mosquito vectors that spread this disease.
Malaria Infection Increases Attractiveness of Humans to Mosquitoes (2005)
Renaud Lacroix, Wolfgang R. Mukabana, Louis Clement Gouagna, Jacob C. Koella
Do malaria parasites enhance the attractiveness of humans to the parasite's vector? As such manipulation would have important implications for the epidemiology of the disease, the question has been...
Lambrechts, Louis, Halbert, Jean, Durand, Patrick, Gouagna, Louis C, Koella, Jacob C
Abstract Background Most studies on the resistance of mosquitoes to their malaria parasites focus on the response of a mosquito line or colony against a single parasite genotype. In natural...

The immune system of invertebrates can mount different responses, including melanotic encapsulation and several antibacterial defense mechanisms. Variation of the efficacies of these responses is...
A parasite might be prohibited from investing simultaneously in horizontal (infection of new hosts) and vertical (infection of the current host's offspring) transmission because of developmental,...

According to current evolutionary dogma, multiple infections generally increase a parasite's virulence (i.e. reduce the host's reproductive success). The basic idea is that the competitive...

To investigate the evolutionary cost of an immune response, we selected six lines of the mosquito Aedes aegypti for earlier or later pupation and measured the extent to which this selection procedure...

Abstract Background Mosquitoes that have been genetically modified to better encapsulate the malaria parasite Plasmodium falciparum are being considered as a possible tool in the control of malaria....
Alex Schwartz, Jacob C. Koella
The melanization responses of field-captured Anopheles gambiae s.l. toward oocysts of the malaria parasite Plasmodium falciparum or negatively charged (C-25) Sephadex beads were determined. Only two...
Koella, Jacob C., Rieu, Linda, Paul, Richard E. L.
We present experimental evidence that different stages of the malaria parasite Plasmodium gallinaceum differentially affect the host-seeking behavior of its mosquito vector Aedes aegypti. In...

Sub-lethal effects of pathogens can lead to the evolution of lower virulence in multiple infections.

Direct and indirect immunosuppression by a malaria parasite in its mosquito vector.
Boëte, Christophe, Paul, Richard E L, Koella, Jacob C
Malaria parasites develop as oocysts within the haemocoel of their mosquito vector during a period that is longer than the average lifespan of many of their vectors. How can they escape from the...

Environmental influence on the genetic basis of mosquito resistance to malaria parasites
Lambrechts, Louis, Chavatte, Jean-Marc, Snounou, Georges, Koella, Jacob C
The genetic basis of a host's resistance to parasites has important epidemiological and evolutionary consequences. Understanding this genetic basis can be complicated by non-genetic factors, such as...
