Malaria parasitemia among blood donors in Uganda

Transfusion, 2020
BACKGROUNDMalaria remains a leading transfusion associated infectious risk in endemic areas. However, the prevalence of malaria parasitemia has not been well characterized in blood donor populations. This study sought to determine the prevalence of Plasmodium in red blood cell (RBC) and whole blood (WB) units after the rainy season in Uganda.METHODS ...

VAR2CSA Signatures of High Plasmodium falciparum Parasitemia in the Placenta [PDF]

PLoS ONE, 2013
Plasmodium falciparum infected erythrocytes (IE) accumulate in the placenta through the interaction between Duffy-binding like (DBL) domains of parasite-encoded ligand VAR2CSA and chondroitin sulphate-A (CSA) receptor. Polymorphisms in these domains, including DBL2X and DBL3X, may affect their antigenicity or CSA-binding affinity, eventually increasing

The role of submicroscopic parasitemia in malaria transmission: what is the evidence?

Trends in Parasitology, 2014
Achieving malaria elimination requires targeting the human reservoir of infection, including those with asymptomatic infection. Smear-positive asymptomatic infections detectable by microscopy are an important reservoir because they often persist for months and harbor gametocytes, the parasite stage infectious to mosquitoes.

Reciprocal positive effects on parasitemia between coinfecting haemosporidian parasites in house sparrows

BMC Ecology and Evolution, 2022
Background Hosts are often simultaneously infected with several parasite species. These co-infections can lead to within-host interactions of parasites, including mutualism and competition, which may affect both virulence and transmission.

PfSPZ-CVac efficacy against malaria increases from 0% to 75% when administered in the absence of erythrocyte stage parasitemia: A randomized, placebo-controlled trial with controlled human malaria infection

PLoS Pathogens, 2021
PfSPZ-CVac combines ‘PfSPZ Challenge’, which consists of infectious Plasmodium falciparum sporozoites (PfSPZ), with concurrent antimalarial chemoprophylaxis.

Annona muricata Linn and Khaya grandifoliola C.DC. Reduce Oxidative Stress In Vitro and Ameliorate Plasmodium berghei-Induced Parasitemia and Cytokines in BALB/c Mice

Journal of Evidence-Based Integrative Medicine, 2021
Background. Annona muricata and Khaya grandifoliola are ethnomedicinally used for the treatment of malaria and have been experimentally shown to have an anti-plasmodial effect, but the mechanisms involved are not fully understood. This study investigated

Parasitemia and its daily variation in canine leishmaniasis [PDF]

Parasitology Research, 2020
The aim of this study was to evaluate, through qPCR, the prevalence of parasitemia in sick kennel dogs naturally infected by canine leishmaniasis. An evaluation of daily changes of the parasitic load in peripheral blood was also performed. A comprehensive clinical examination and the collection of several samples (blood, lymph node, skin, and ...

High Incidence of Severe Parasitemia in Falciparum Malaria: REPLY [PDF]

Medical Journal Armed Forces India, 2002
Dear Editor, I thank Lt Col A Banerjee for his thoughtful response to our letter. Prolonged exposure over generations should select out a relatively immune population in endemic areas of falciparum malaria. The emergence of such immunity would restrict parasitemia, the patient becoming symptomatic once the degree of parasitemia increases.

Early reduction of Leishmania infantum-specific antibodies and blood parasitemia during treatment in dogs with moderate or severe disease [PDF]

Parasites & Vectors, 2016
Leishmania infantum-specific antibodies are used extensively for the diagnosis and monitoring of treatment in canine leishmaniosis. Different views have been described for the measurement of L.
