Although infections are seldom fatal clinical disease can be debilitating and imposes significant health and economic impacts on affected populations Globally, Plasmodium falciparum and Plasmodium vivax account for the majority of cases of malaria. While Plasmodium falciparum is responsible for more deaths, Plasmodium vivax is the most widespread of all of the malaria species, can cause severe, even fatal infections and results in significant global morbidity and mortality Plasmodium vivax is more geographically dispersed than Plasmodium falciparum, with transmission occurring over a wider range of temperatures than for P. falciparum [ 1 ], and at latitudes as far as 64° North [ 2 ] Plasmodium falciparum is the predominant species in the world. P. vivax and P. ovale are traditionally thought to occupy complementary niches, with P. ovale predominating in Sub-Saharan Africa and P. vivax in the other areas; but their geographical ranges do overlap

strains of the malarial parasites Plasmodium vivax, P. ovale, and P. falciparum as well as certain parasitic worms and amoebas. It is also used in the treatment of inflammatory rheumatic diseases, such as lupus erythematosus and rheumatoid arthritis Plasmodium vivax is frequently considered to be less important because it often causes a milder form of the disease that has a lower fatality rate. An infection may still be deadly, however. In addition, outside of Africa P. vivax is a more common cause of malaria than P. falciparum

  1. Plasmodium vivax ist ein einzelliger Parasit aus der Gattung Plasmodium und ein Krankheitserreger der Malaria tertiana.Infektionen durch Plasmodium vivax sind häufig, und obwohl die Erkrankung als meist relativ gutartig verlaufend angesehen wird, trägt der Erreger mit geschätzten 132 bis 391 Millionen Infektionen pro Jahr in den betroffenen Ländern erheblich zur Morbidität bei
  2. Caratteristiche generali. Il Plasmodium vivax è un protozoo parassita intracellulare obbligato, necessita di un ospite vertebrato (l'uomo) e di un ospite invertebrato (la zanzara Anopheles, che ne è anche il vettore).Il Plasmodium vivax è la specie responsabile della malaria più diffusa al mondo. Infatti è presente anche in aree a clima più temperato rispetto a Plasmodium falciparum, e.
  3. Plasmodium vivax (P. vivax) is unique in that it has preference for immature reticulocytes during its erythrocytic cycle . Duffy antigen receptor for chemokines (DARC) also called cluster of differentiation 234 (CD234) or atypical chemokine receptor (ACKR) is a receptor for a family of proinflammatory chemokines [8,9,10]

Cytoadherence and sequestration in the microvasculature are central to the pathogenesis of severe Plasmodium falciparum malaria, but the contribution of cytoadherence to pathology in other human malarias is less clear Plasmodium is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, Plasmodium is in the order Haemosporida and family Plasmodiidae. Over 200 species of Plasmodium have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range

  1. Plasmodium parasites are the agents responsible for malaria, one of the worst scourges of mankind, with almost 600,000 infant deaths and about 200 million clinical cases reported each year [ 1 ]. Among the five Plasmodium species infecting humans, Plasmodium vivax is the most prevalent parasite outside Africa [ 2 ]
  2. Plasmodium vivax multiple antigen constructs (MACs) of CSP vaccines have shown some protection in New World monkeys against P. vivax sporozoite challenge showing 40% efficacy or less that waned over several months , which is similar to the efficacy reported in field trials for RTS, S. The multiple antigen peptide vehicles though have lost.
  3. P. vivax infection is characterized by induction of periodical asymptomatic infection or clinical episodes due to spontaneous activation of hypnozoites, dormant parasite liver forms that do not occur in P. falciparum infections [ 2 ]
  4. Plasmodium vivax. Plasmodien sind als Malaria-Erreger bekannt und werden von der Anopheles-Mücke auf einen Wirt übertragen, in dem sie sich parasitär vermehren. Plasmodium vivax ist einer von vier Erregern der Malaria. Die durch den Parasiten verursachte Malaria-Form ist die sogenannte Malaria tertiana, die als leichtere Verlaufsform der Erkrankung gilt

Current treatment of vivax malaria by 3 days of chloroquine and 14 days of low dose of primaquine suffers from poor compliance Such results showed that, despite AMA-1 having universal functions during late Plasmodium invasion stages, PvAMA-1 had reticulocyte-preferring binding regions, suggesting that P. vivax target cell selection is not just restricted to initial interactions but maintained throughout the erythrocyte invasion cycle, having important implications for.

Plasmodium vivax is a widely distributed protozoal parasite and a human pathogen that is responsible for human malaria. P vivax is not virulent as compared to Plasmodium falciparum. Plasmodium vivax can cause severe disease and death due to the enlargement of the spleen. They are transmitted through the female Anopheles mosquito. Classification of Plasmodium vivax

Plasmodium vivax is the only species of Plasmodium prevalent in the highland regions of Peru. Interestingly, the patient presents with several features of severe and complicated malaria, including severe anaemia, jaundice and impaired consciousness. However, P. vivax is less commonly associated with severe malaria than P. falciparum. Plasmodium vivax malaria is endemic and often neglected protozoal infection that is distinguished by a delayed clinical presentation and a milder clinical course in the initial stages of the disease. Fever, chills, hepatosplenomegaly and anemia are most important symptoms. The diagnosis can be made through several tests, but a thorough clinical assessment is vital for raising suspicion toward. Plasmodium vivax causes benign tertian malaria, so called, be­cause the paioxysm of fever occurs every other day and the disease is rarely fatal. Plasmodium is an endoparasite which lives within the red blood corpuscles of man to whom it is transmitted by the bite of an infected female mosquito Incubation period: The period between infection and the appearance of first symptoms is called incubation period. It is about 10-14 days in Plasmodium vivax. Pre-patent period: The duration between the initial sporozoites infection and the first appearance of parasites in the blood is called as pre-patient period
