Blood-stage malaria parasites evade the immune system by switching the protein exposed at the surface of the infected erythrocyte. A small proportion of these parasites commits to sexual development to mediate mosquito transmission. Two studies in this issue (Brancucci et al., 2014; Coleman et al., 2014) shed light on shared epigenetic machinery underlying both of these events.

Projections related to future climate warming indicate the potential for an increase in the distribution and prevalence of blood parasites in northern regions. However, baseline data are lacking for resident avian host species in Alaska. Grouse and ptarmigan occupy a diverse range of habitat types throughout the northern hemisphere and are among the most well-known and important native game bir...

The evolution of drug resistant Plasmodium parasites is a major challenge to effective malaria control. In theory, competitive interactions between sensitive parasites and resistant parasites within infections are a major determinant of the rate at which parasite evolution undermines drug efficacy. Competitive suppression of resistant parasites in untreated hosts slows the spread of resistance;...

Background: .
 Malaria is serious vector –borne tropical diseases that remains one of the primary reasons for death in several countries . and typhoid co-infection a major public health problem many developing countries. Most co-infections treated are based on methods diagnosis plagued with assumptions which possibly exaggerate situation. Objective: This aim this work was to investigate ra...

Resistance of Plasmodium falciparum to chloroquine has been reported in many areas in Ghana. Most of these reports, which are from hospital-based studies, indicate RI and RII rather than RIII type of resistance. Since high pretreatment levels of chloroquine have also been measured in patients with malaria infection in Ghana, we hypothesized that the 'added effect' of the pretreatment ingested d...

Introduction Parasites play important roles in ecosystems. Through their interactions with host and vector species, they are capable of changing the behavior population dynamics shape entire communities. Over past years, many studies have acknowledged role parasitism for populations communities discovered regulatory functions vertebrate populations. Although birds a well-studied group vertebrat...

the possible existence of equine piroplasmosis was investigated in the province of quezon, philippines. blood samples of 269 horses from selected municipalities of quezon province were gathered. parasitological test namely blood parasite examination was employed and the test yielded negative results for the presence of the parasite. similarly, polymerase chain reaction assay was performed using...

During their development within the vertebrate host, Plasmodium parasites infect hepatocytes and red blood cells. Within these cells, parasites are surrounded by a parasitophorous vacuole membrane (PVM). The PVM plays an essential role for the interaction of parasites with their host cells; however, only a limited number of proteins of this membrane have been identified so far. This is partiall...

Gametocyte maturation in Plasmodium falciparum is a critical step in the transmission of malaria. While the majority of parasites proliferate asexually in red blood cells, a small fraction of parasites undergo sexual conversion and mature over 2 weeks to become competent for transmission to a mosquito vector. Immature gametocytes sequester in deep tissues while mature stages must be able to cir...
