چکیده

A survey of asymptomatic children in Uganda showed Plasmodium malariae and P. falciparum parasites in 45% and 55% of microscopy-positive samples, respectively. Although 36% of microscopy-positive samples were negative by rapid diagnostic test, 75% showed P. malariae or P. ovale parasites by PCR, indicating that routine diagnostic testing misses many non-P. falciparum malarial infections.

Transmission-dependent tolerance to multiclonal Plasmodium falciparum infection.

Whether the number of concurrent clones in asymptomatic Plasmodium falciparum infections reflects the degree of host protection was investigated in children living in areas with different levels of transmission on the coast of Kenya. The number of concurrent clones was determined on the basis of polymorphism in msp2, which encodes the vaccine candidate antigen merozoite surface protein 2. In a ...

Molecular Evidence on Changing Pattern of Mixed Plasmodium falciparum and P. vivax Infections during Year-Round Transmission of Malaria in Chahbahar, Iran

Mixed malaria infections, Plasmodium falciparum and P. vivax, are suspected to occur at a greater frequency than is detected by conventional light microscopy. In order to determine the year round pattern of transmission and the frequency of mixed infections in malaria endemic area, we carried out a prospective comparison of diagnosis by conventional light microscopy and nested PCR in Chahbahar ...

Malaria Elimination Program: Absence of asymptomatic malaria and low parasitic in endemic area of Rudan district, Hormozgan Province, Iran

Introduction: Malaria is a major global public health problem and a leading cause of morbidity and mortality in many countries. Malaria elimination is the common goal of World Health Organization and the health system in Iran. Following a decline in malaria cases in recent years, the malaria elimination program, technically supported by the WHO, has initiated since 2009 in Iran. In order to suc...

Substantial asymptomatic submicroscopic Plasmodium carriage during dry season in low transmission areas in Senegal: Implications for malaria control and elimination

BACKGROUND In the progress towards malaria elimination, the accurate diagnosis of low-density asymptomatic infections is critical. Low-density asymptomatic submicroscopic malaria infections may act as silent reservoirs that maintain low-level residual malaria transmission in the community. Light microscopy, the gold standard in malaria diagnosis lacks the sensitivity to detect low-level parasit...

Microscopic and molecular evidence of the presence of asymptomatic Plasmodium falciparum and Plasmodium vivax infections in an area with low, seasonal and unstable malaria transmission in Ethiopia.

BACKGROUND The presence of asymptomatic infections has serious implications for malaria elimination campaigns. Since asymptomatic carriers do not seek treatment for their infection and may become gametocyte carriers, they undoubtedly contribute to the persistence of malaria transmission in a population. The presence of asymptomatic parasitemias was noted in areas with seasonal malaria transmiss...
