Variants of the Plasmodium vivax circumsporozoite protein (VK210 and VK247) in Colombian isolates

Memorias do Instituto Oswaldo Cruz, 2001
Phenotypic diversity has been described in the central repeated region of the circumsporozoite protein (CSP) from Plasmodium vivax. Two sequences VK210 (common) and VK247 (variant) have been found widely distributed in P.

Cellular Hallmarks From Volume Electron Microscopy Reveal Developmental Progression of Plasmodium Ookinetes

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This article presents a detailed ultrastructural cell atlas of Plasmodium ookinete development using advanced volume electron microscopy (v) techniques. It defines seven distinct developmental stages, revealing complex organelle interactions and offering new insights into parasite differentiation.

A comparative study on the vector competence of Anopheles stephensi from geographically distinct malarious and non-malarious urban areas in India to the malarial parasite, Plasmodium vivax

Journal of Vector Borne Diseases
Background & objectives: Anopheles stephensi is responsible for the transmission of malaria in urban areas. Vector competence of An. stephensi from a non-malarious (Coimbatore) and highly malarious (Chennai) urban area were investigated to find out the ...

Development of sporogonic cycle of Plasmodium vivax in experimentally infected Anopheles albimanus mosquitoes

Memorias do Instituto Oswaldo Cruz, 1994
The sporogonic cycle of Plasmodium vivax was established and maintained under laboratory conditions in two different strains of Anopheles albimanus mosquitoes using as a parasite source blood from human patients or from Aotus monkeys infected with the ...

Effects of Betaine on Performance, Blood Biochemistry, Nutrient Utilization and Gut Health in Coccidia‐Infected Broilers

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Betaine supplementation improved growth performance, nutrient digestibility, blood lipid profiles and caecal lesion scores in broilers experimentally challenged with coccidiosis, with the greatest benefits observed at 600 mg/kg, highlighting its potential as a supportive dietary strategy against coccidial infection. ABSTRACT The objective of this study

Avian Malaria Among House Sparrows: a Survey of Disease and Mosquito Vectors (Diptera: Culicidae) in Reed City, Michigan [PDF]

, 2017
Nine of 350 house sparrows caught in Reed City, Michigan, had malaria parasites detectable on Giemsa-stained thin films. All of the infected birds were juveniles, Parasitemias were too low to permit identification of the Plasmodium present. Collection of

Plasmodium sporozoite-host cell interactions during sporozoite invasion.

Bulletin of the World Health Organization, 1991
In vitro and in vivo studies were performed to clarify the nature of some interactions between Plasmodium berghei sporozoites and rodent host cells. Videomicroscopic observations were made on in vitro interactions between sporozoites and cultured host cells (rodent peritoneal macrophages, W138 human lung fibroblasts, and HepG2 human hepatoma cells ...

Priming of CD8+ T cell responses following immunization with heat-killed Plasmodium sporozoites.

, 2006
Protective immune responses against malaria are induced by immunization with radiation-attenuated Plasmodium sporozoites. In contrast, non-viable, heat-killed sporozoites do not induce protection, emphasizing the requirement for live parasites to achieve

Plasmodium berghei rhoptry neck protein 6 maintains parasite infectivity and virulence

mBio
Apicomplexan parasites possess unique secretory organelles called rhoptries, which are reservoirs for rhoptry neck proteins (RONs) and rhoptry bulb proteins (ROPs) that aid in host cell attachment, invasion, and intracellular proliferation. In Plasmodium
