Antibody and B cell responses to Plasmodium sporozoites [PDF]

open access: yes, 2014
Antibodies are capable of blocking infection of the liver by Plasmodium sporozoites. Accordingly the induction of anti-sporozoite antibodies is a major aim of various vaccine approaches to malaria.

Viral proteins expressed in the protozoan parasite Eimeria tenella are detected by the chicken immune system [PDF]

open access: yes, 2016
BACKGROUND: Eimeria species are parasitic protozoa that cause coccidiosis, an intestinal disease commonly characterised by malabsorption, diarrhoea and haemorrhage that is particularly important in chickens.

Infectivity of Symptomatic Patients and Their Contribution for Infectiousness of Mosquitoes following a Membrane Feeding Assay in Ethiopia

open access: yesMicrobiology Spectrum, 2022
The membrane feeding assay is widely used to evaluate the efficacy of transmission-blocking interventions (TBIs) and identify the reservoir of malaria.

Induction and maintenance of protective CD8+ T cells against malaria liver stages: implications for vaccine development

open access: yesMemorias do Instituto Oswaldo Cruz, 2011
CD8+ T cells against malaria liver stages represent a major protective immune mechanism against infection. Following induction in the peripheral lymph nodes by dendritic cells (DCs), these CD8+ T cells migrate to the liver and eliminate parasite infected

Theoretical implications of a pre-erythrocytic Plasmodium vivax vaccine for preventing relapses [PDF]

open access: yes, 2017
Preventing malaria infection through vaccination requires preventing every sporozoite inoculated by mosquito bite: a major challenge for Plasmodium falciparum.

In vitro: Anti-coccidia activity of Calotropis procera leaf extract on Eimeria papillata oocysts sporulation and sporozoite

open access: yesOpen Chemistry, 2022
Natural products play an important role as environmentally friendly agents that can be used against parasitic diseases. Many Eimeria species cause eimeriosis in poultry. The negative effects of synthetic anti-coccidiosis medications necessitate the quest

Malaria Diagnosis and the Plasmodium Life Cycle: the BFO Perspective [PDF]

open access: yes, 2009
Definitive diagnosis of malaria requires the demonstration through laboratory tests of the presence within the patient of malaria parasites or their components.

KAI407, a potent non-8-aminoquinoline compound that kills Plasmodium cynomolgi early dormant liver stage parasites in vitro. [PDF]

open access: yes, 2014
Preventing relapses of Plasmodium vivax malaria through a radical cure depends on use of the 8-aminoquinoline primaquine, which is associated with safety and compliance issues.

Hijacking the human complement inhibitor C4b-binding protein by the sporozoite stage of the Plasmodium falciparum parasite

open access: yesFrontiers in Immunology, 2022
The complement system is considered the first line of defense against pathogens. Hijacking complement regulators from blood is a common evasion tactic of pathogens to inhibit complement activation on their surfaces.

Copper-transporting ATPase is important for malaria parasite fertility [PDF]

open access: yes, 2013
Homeostasis of the trace element copper is essential to all eukaryotic life. Copper serves as a cofactor in metalloenzymes and catalyses electron transfer reactions as well as the generation of potentially toxic reactive oxygen species. Here, we describe
