Diagnosis of malaria by acridine orange fluorescent microscopy in an endemic area of venezuela.
Fluorescent (acridine orange) microscopical examination of capillary centrifuged blood (quantitative buffy coat [QBC] analysis) and Giemsa stained thick blood smears (GTS) were compared for diagnosis… Expand
Caveolins and flotillin-2 are present in the blood stages of Plasmodium vivax
Blood stages of Plasmodium vivax induce the development of caveolae and caveola–vesicle complexes (CVC) in the membrane of their host erythrocyte. Caveolae are found in almost all types of cells and… Expand
Plasmodium vivax: detection of blood parasites using fluorochrome labelled monoclonal antibodies
A monoclonal antibody (MoAb) 2C6111 specific for Plasmodium vivax erythrocytic stages was shown to detect parasitized erythrocytes in blood samples collected in the field. This MoAb binds to the… Expand
An immunocytochemical test for the diagnosis of antibodies to Plasmodium vivax
Summary An immunocytochemical peroxidase test (ICPT) has been developed to allow serological measurement of the antibody response to Plasmodium vivax by light microscopy. Acetone fixed P. vivax… Expand

The objective of this work was to determine the prevalence of anemia and deficiencies of iron, folic acid and vitamin B12 in Betania del Topocho, a Piaroa community from Estado Amazonas, Venezuela, a… Expand
Sensitive detection of Plasmodium vivax in blood by a cell-ELISA using a monoclonal antibody.
An IgM monoclonal antibody (7C5B71) which reacted with the blood stages of Plasmodium vivax, but not with those of Plasmodium falciparum was used in a cell-ELISA to detect parasites in samples of… Expand

Abstract. We investigated the secretory traffic of a Plasmodium vivax antigen (Pv-148) synthesised by the parasite during the blood cycle, exported into the host cell cytosol and then transported to… Expand
Plasmodium vivax and P. chabaudi: inter-species cross-reacting antigens
Abstract A monoclonal antibody raised by immunization of BALB/c mice with erythrocytic stages of Plasmodium vivax was shown to react with asexual erythrocytic stages of P. chabaudi. The… Expand
