Analysis of diagnostic biomarkers for malaria: Prospects on rapid diagnostic test (RDT) development.

Accurate malaria diagnosis remains a formidable challenge in remote regions of malaria-endemic areas globally. Existing diagnostic methods predominantly rely on microscopy and rapid diagnostic tests (RDTs). While RDTs offer advantages such as rapid results and reduced dependence on highly skilled technicians compared to microscopy, persistent challenges emphasize the critical need to identify novel diagnostic biomarkers to further enhance RDT based malaria diagnosis.

Vivax malaria: a possible stumbling block for malaria elimination in India.

is geographically the most widely dispersed human malaria parasite species. It has shown resilience and a great deal of adaptability. Genomic studies suggest that originated from Asia or Africa and moved to the rest of the world.

Genetic differentiation among Aedes aegypti populations from different eco-geographical zones of India.

The present study explicitly evaluated the genetic structure of Aedes aegypti Linn, the vector of dengue, chikungunya, and Zika viruses, across different geo-climatic zones of India and also elucidated the impact of ecological and topographic factors. After data quality checks and removal of samples with excess null alleles, the final analysis was performed on 589 individual samples using 10 microsatellite markers. Overall findings of this study suggested that, Ae.

Characterization of midgut microbiome of Liston.

Background & Objectives: Anopheles stephensi is an important vector of malaria in South East Asia. The abundance and diversity of gut microbiota in the disease vectors affect their development, digestion, metabolism and immunity. The immatures of An.

Clinical and epidemiological characterization of severe malaria in Gujarat, India.

The mounting evidence supporting the capacity of to cause severe disease has prompted the need for a better characterization of the resulting clinical complications. India is making progress with reducing malaria, but epidemics of severe vivax malaria in Gujarat, one of the main contributors to the vivax malaria burden in the country, have been reported recently and may be the result of a decrease in transmission and immune development. Over a period of one year, we enrolled severe malaria patients admitted at the Civil Hospital in Ahmedabad, the largest city in Gujarat, to investigate the morbidity of severe vivax malaria compared to severe falciparum malaria.

A Proteogenomic Analysis of Haptoglobin in Malaria.

Scope: Haptoglobin (Hp), an acute phase inflammatory protein is associated with malaria pathogenesis in several proteomics and genomics studies. The Hp gene has two co-dominant alleles: Hp1 and Hp2 that produce three genotypes: Hp1/Hp1, Hp1/Hp2 and Hp2/Hp2.

Experimental Design: In this study, validation of the proteomics data with Multiple Reaction Monitoring Mass Spectroscopy (MRM-MS) is performed and the association of the Hp gene variants with severe, non-severe malaria and community (healthy) controls using genotyping PCRs and DNA sequencing is analysed.

Mitochondrial population genomic analyses reveal population structure and demography of Indian Plasmodium falciparum.

Inference on the genetic diversity of Plasmodium falciparum populations could help in better management of malaria. A very recent study with mitochondrial (mt) genomes in global P. falciparum had revealed interesting evolutionary genetic patterns of Indian isolates in comparison to global ones.

Mitochondrial genome sequence diversity of Indian Plasmodium falciparum isolates.

We have analysed the whole mitochondrial (mt) genome sequences (each ~6 kilo nucleotide base pairs in length) of four field isolates of the malaria parasite Plasmodium falciparum collected from different locations in India. Comparative genomic analyses of mt genome sequences revealed three novel India-specific single nucleotide polymorphisms. In general, high mt genome diversity was found in Indian P.

New insights into the evolutionary history of Plasmodium falciparum from mitochondrial genome sequence analyses of Indian isolates.

Estimating genetic diversity and inferring the evolutionary history of Plasmodium falciparum could be helpful in understanding origin and spread of virulent and drug-resistant forms of the malaria pathogen and therefore contribute to malaria control programme. Genetic diversity of the whole mitochondrial (mt) genome of P. falciparum sampled across the major distribution ranges had been reported, but no Indian P.

Whole mitochondrial genome sequence of an Indian Plasmodium falciparum field isolate.

Mitochondrial genome sequence of malaria parasites has served as a potential marker for inferring evolutionary history of the Plasmodium genus. In Plasmodium falciparum, the mitochondrial genome sequences from around the globe have provided important evolutionary understanding, but no Indian sequence has yet been utilized. We have sequenced the whole mitochondrial genome of a single P.

Comparative genomic analysis of simple sequence repeats in three Plasmodium species.

Simple sequence repeats (SSRs) are known to be responsible for genetic complexities and play major roles in gene and genome evolution. To this respect, malaria parasites are known to have rapidly evolving and complex genomes with complicated and differential pathogenic behaviors. Hence, by studying the whole genome comparative SSRs patterns, one can understand genomic complexities and differential evolutionary patterns of these species.
