BACKGROUND & OBJECTIVE Though the relationship between mosquito density and transmission of malaria in different regions of the country is known, no studies are available on the relationship between mosquito catches and malaria cases in Kalsi area of Dehradun district in Uttaranchal. Hence, the present study was done to evaluate the role of anopheline mosquitoes catches and prevalence of malari...

Malaria is one of the most prevailing fatal diseases causing between 1.2 and 2.7 million deaths all over the world each year. Further, development of resistance against the frontline anti-malarial drugs has created an alarming situation, which requires intensive drug discovery to develop new, more effective, affordable and accessible anti-malarial agents possessing novel modes of action. Over t...

Antibody-dependent cell-mediated cytotoxicity (ADCC) against mouse erythrocytes sensitized with immunoglobulin G was studied in mice with malaria. Spleen cells from mice had enhanced cytotoxic activity early in Plasmodium berghei infection but not later in the disease. Sera from infected animals and partially purified malarial immune complexes inhibited ADCC. In addition, ADCC was diminished in...

The malarial GBP 130 protein binds weakly to intact human erythrocytes; the binding sites seem to be located in the repeat region and this region's antibodies block the merozoite invasion. A peptide from this region (residues from 701 to 720) which binds to human erythrocytes was identified. This peptide named 2220 did not bind to sialic acid; the binding site on human erythrocyte was affected ...

Pyrimethamine is an antimalarial drug which possesses schizonticidal activity in both tissue and blood phases. Though pyrimethamine is known to inhibit folic acid metabolism of malarial parasites by binding with folio acid reductase (6), the cytological effect on the parasites is not completely understood. To our knowledge, there has been no study until now on the morphological effects of pyrim...

Recent work suggests that IgG and IgM from nonimmune human serum (natural antibodies) bind to the surface of Plasmodium falciparum-infected erythrocytes and contribute to rosette formation by stabilizing the interaction between infected and uninfected erythrocytes. Here we show, in both laboratory clones and field isolates, that only IgM but not IgG is detected on the surface of infected cells....

A genomic Leishmania major DNA expression library was screened using antibodies raised against L. major membranes. Two different clones were identified that encoded proteins containing regions of tandemly repeated peptides. Clone 20 encodes a repetitive peptide of 14 amino acids, while clone 39 encodes a repetitive peptide of 10 amino acids. DNA from clone 20 hybridized with two RNA species of ...

Schoolchildren from 2 areas of Kenya, Kangundo and Kambu, have contrasting prevalences of hepatosplenomegaly, despite having similar prevalences and intensities of Schistosoma mansoni infection. However, in individual children, S. mansoni infection intensity is positively correlated with organomegaly. In a previous study, hepatosplenomegaly was associated with Th1-type anti-schistosome cytokine...

background: electrolytes play an important role in the normal functioning of human body. electrolyte imbalance and mineral disturbances is the common clinical manifestation in several infectious diseases including malaria. malaria is a mosquito borne serious infectious disease of the world. plasmodium vivax and p. falciparum are the main agents responsible for malaria in pakistan. electrolyte i...
