Malaria remains a significant global health challenge, with the deadliest infections caused by . In light of the escalating drug resistance and the limited effectiveness of available vaccines, innovative treatment approaches are urgently needed. This study explores the potential of the probiotic YZ01, isolated from traditionally fermented kindirmo milk, to modify host responses to ANKA infection.

Rapid diagnostic tests (RDTs) are crucial for diagnosing malaria in resource-limited settings. These tests, which detect the histidine-rich protein 2 (PfHRP2) and its structural homologue PfHRP3, are specifically designed to identify Plasmodium falciparum. Deletion of the Pfhrp2 gene in parasite has been reported in India and other malaria-endemic countries.

Article Synopsis
  • Urbanization and varying microclimates in cities affect mosquito behavior and malaria transmission, particularly in urban slums.
  • This study analyses how different household roof types (thatched, asbestos, tiled) impact the survival of Anopheles stephensi mosquitoes and the development of Plasmodium vivax.
  • Findings reveal that thatched roofs promote higher parasite development and mosquito survival compared to asbestos and tiled roofs, highlighting the significance of environmental factors in malaria control strategies.

Assessment of the quality of malaria surveillance and laboratory services for diagnosis in three districts of Gujarat state, India.

Front Public Health

December 2024

Vector Borne Diseases Control Program, Government of Gujarat, Gandhinagar, Gujarat, India.

Objectives: Surveillance is the backbone for the control of malaria and its elimination. In the state of Gujarat, situated in the western region of India, some of the districts reported a high annual blood examination rate (ABER) for malaria. Therefore, a study was conducted to identify the underlying reasons for the increase in the ABER for malaria.

The survival of mosquitoes under changing climatic conditions particularly temperature, is known to be supported by Heat Shock Proteins (HSPs). In view of climate change, it is imperative to know whether the mosquito vectors will be able to withstand the increased temperatures or perish. Therefore, the present study was undertaken on the expression of HSPs' gene in An.

Filariasis is one of the oldest, most dangerous, debilitating, disfiguring diseases and often ignores tropical disorders. It presents with a range of clinical symptoms, a low death rate, and a high morbidity rate, which contributes to social discrimination. This condition has major effects on people's socioeconomic circumstances.

Malaria is a deadly blood-borne disease caused by a Plasmodium parasite. Infection results in various forms of malaria, including an asymptomatic state, uncomplicated disease, or severe disease. Severe malaria (SM) is particularly prevalent among young children and is a significant cause of mortality.

Microhaplotypes: the QR-code for Plasmodium vivax infection dynamics.

Trends Parasitol

An array of microhaplotypes - small segments of ≤200 nucleotides with heterozygous multiple-SNP exhibiting multiple allelic combinations - were identified in the Plasmodium vivax genome by Siegel et al. Interestingly, the microhaplotype has significant potential to distinguish relapse/reinfection and identify genetic relatedness across vivax-endemic areas. It is essential to validate the universal applicability of microhaplotypes.

Article Synopsis
  • Mosquitoes are major disease carriers affecting global health, and their diversity changes with climate and breeding habitats across different seasons.
  • A study in Ganjam, Odisha, evaluated mosquito diversity in rural, peri-urban, and urban areas to predict disease transmission risks, revealing higher species richness and abundance in peri-urban locations.
  • The study suggests that while increased mosquito species richness may lower disease risk, greater dominance of vector species in new habitats can lead to new disease outbreaks, with a noted risk of lymphatic filariasis, malaria, and dengue/chikungunya in various areas.

Article Synopsis
  • The study evaluated the effectiveness and tolerability of the antimalarial drug ganaplacide in combination with lumefantrine solid dispersion (LUM-SDF) for treating uncomplicated falciparum malaria across various age groups in a Phase II clinical trial.
  • The trial consisted of three parts: a run-in phase assessing pharmacokinetic interactions, a regimen comparison in adults and adolescents, and a dosage assessment in children aged 2 to under 12 years.
  • Results indicated that co-administration of ganaplacide and LUM-SDF did not significantly alter drug exposure levels, with both drugs showing adequate exposure for efficacy across different age and weight groups, despite some variability.

Unlabelled: Malaria is one of the most infectious disease that affects lives of million people throughout the world. Recently, there are several reports which indicate causing severe disease in infected patients from different parts of the world. For disease severity, the data related to immunological and inflammatory status in human host is very limited.

Chemical insecticides (organophosphates and pyrethroids) in the form of IRS (Indoor Residual Sprays) and LLINs (Long Lasting Insecticidal Nets) are the cornerstone for vector control, globally. However, their incessant use has resulted in widespread development of resistance in mosquito vectors, warranting continuous monitoring and investigation of the underlying mechanisms of resistance. Here, we identified a previously uncharacterized- Cub and Sushi Domain containing Insecticide Resistance (CSDIR) protein and generated evidence for its role in mediating insecticide resistance in the Anopheles stephensi.

Anopheles jamesii, considered to be a non-malaria vector, is an abundant mosquito species found in coastal India and several countries in Asia. In Goa, western India, An. jamesii is the dominant anopheline species by numbers, and in recent epidemiological surveys, they have tested positive for Plasmodium carriage.

The threat of zoonotic malaria remains largely overlooked in India, particularly in regions such as the Western Ghats (WG), a biodiversity hotspot. The WG has diverse species of non-human primates that serve as reservoir hosts for simian malaria parasites. The presence of the Leucosphyrus group of mosquitoes and other vectors of human malaria makes WG vulnerable to the risk of parasite spillover.

Objectives: India is vigorously pursuing malaria elimination by 2030 and one of the key challenges is how to prevent the malaria risk associated with long-distance migrations of populations from endemic to non-endemic areas. Millions of pilgrims walking to the holy Ramdevra temple stay in temporary shelters along the route in district of Jaisalmer, Rajasthan state in western India. The main pilgrimage period coincides with the post-monsoon period with elevated vector densities.

Purpose: Primaquine (PQ) is recommended for radical cure of Plasmodium vivax (Pv) malaria, but its utilization is still limited due to high risk of severe haemolytic anaemia in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD-d). The aim of the present study is to assess the different genotypic variants leading to G6PD-d in Delhi and Goa regions of India.

Methods: A total of 46 samples (34 retrospective Pv-mono-infected samples and 12 Pv-uninfected samples) were included in the study.

Article Synopsis
  • Prolyl-tRNA synthetase (PRS) is a crucial enzyme for protein translation and a key target for malaria treatments.
  • Five newly developed ATP mimetics (L95, L96, L97, L35, and L36) show improved stability when interacting with L-proline, with L35 demonstrating the highest thermal stability and effectiveness similar to halofuginone.
  • L35 has a potent inhibitory effect (∼1.6 nM) against the asexual-blood-stage of the malaria parasite and exhibits a significant selectivity, meaning it targets the parasite more effectively than human proteins, showcasing potential for new drug development.
