The distributions of human malaria parasite species overlap in most malarious regions of the world, and co-infections involving two or more malaria parasite species are

Malaria is a life-threatening mosquito-borne disease caused by the Plasmodium parasite, responsible for more than half a million deaths annually and principally involving

In most areas where malaria is endemic, two or more human plasmodial species coexist and it is becoming increasingly apparent that the different Plasmodium parasites

Species-transcending Regulation of Malaria Parasitaemia

The dynamics of longitudinal parasitaemia data from Plasmodium-infected humans give a unique insight into how Plasmodium infections are regulated. In a study of Abstract Malariologists have long been fascinated by the question of whether Plasmodium spp. interact in the human host. The first genetic study of the longitudinal dynamics of multiple Past research has demonstrated the capacity of this malaria parasite species to successfully adapt and proliferate within human hosts, highlighting its potential to cross the

This paper uses published epidemiological data to demonstrate an interaction among the species of human malaria that is expected from ecological and evolutionary theory

Abstract The infection dynamics between different species of Plasmodium that infect the same human host can both suppress and exacerbate disease. This could arise from inter-parasite Much of our understanding of the natural history of human malaria derives from observations of untreated infection in the first half of the century (Kitchen, 1949). An important feature of human Factors associated with malaria parasitaemia, malnutrition, and anaemia among HIV-exposed and unexposed Ugandan infants: a cross-sectional survey

Host-pathogen interactions in malaria. During infection with P. falciparum, both human and mosquito hosts exhibit responses that reflect physiological changes to infection (insulin/IGF-1) Superinfection with Plasmodium species increases the risk of fatal disease in individuals with low immunity, yet it is not frequent in young children. Portugal et al. provide a It is proposed that malaria parasitemia is controlled in a density-dependent manner in these semi-immune children and that a cross-species mechanism of parasite regulation exists.

The advent of controlled human malaria infection (CHMI) as a tool to study vaccine efficacy and identifying pathways to protective immunity reveals interesting and The dynamics of longitudinal parasitaemia data from Plasmodium-infected humans give a unique insight into how Plasmodium infections are regulated. In a study of asymptomatic, multiple Identification of the four human malaria parasite species in field samples by the polymerase chain reaction and detection of a high prevalence of mixed infections.

The characteristics and distribution of malaria species, anopheline mosquitoes, the individual host and their interaction determine the spectrum of mixed infections. The global

Host-Malaria Parasite Interactions and Impacts on Mutual Evolution

This was later expanded to a general model for the regulation of malaria parasitaemia where the density-triggered nonspecific transient regulators of parasite numbers In regions of high rates of malaria transmission, mosquitoes repeatedly transmit liver-tropic Plasmodium sporozoites to individuals who already have blood-stage parasitemia. Transfer of cross-species miRNAs between host and parasites is a novel and critical aspect of host–parasite interactions. MiRNA-mediated cross-species regulation may

Malaria parasites are arguably the most extensively studied pathogens. Yet, despite enormous epidemiological and clinical observations, we remain remarkably uncertain of the day-to-day

1 Crossreactive Immunity Longitudinal studies in experimental models of blood-stage malaria infection have indicated that infection dynamics are affected by cross-species immunity. An Show more View article Review article Cross-species regulation of malaria parasitaemia in the human host 2002, Current Opinion in Microbiology Marian C Bruce, Karen P Day Inducible In children from the less malaria-susceptible Fulani ethnic group, we observe opposing responses following infection, consistent with the immunosuppressive role of

While the immune response to Plasmodium falciparum malaria has been studied extensively, the circulating proteome and its cellular origins remain poorly characterized. Therefore, P. knowlesi is still considered a zoonotic malaria. Life Cycle The malaria parasite life cycle involves two hosts.

Further, we argue that a closer examination of malaria parasites within their primeval insect hosts can reveal the most fundamental aspects of host–pathogen interactions In areas of the world that are endemic for malaria, humans often harbour a complex mixture of different species and/or genotypically distinct isolates of the same malaria species[1,2]. One Malaria parasites are arguably the most extensively studied pathogens. Yet, despite enormous epidemiological and clinical observations, we remain remarkably uncertain of the day-to-day

Oxidative stress is a major contributor of disease aetiology, progression and outcomes. Host systems and parasite infectivity play critical roles in the generation and Although a few studies indicate that some cross-protection between Plasmodium vivax, the most widely distributed human malaria parasite, and P. falciparum, the most virulent
