Ahead of World Toilet Day, which is marked annually on 19 November, WSSCC’s acting Executive Director, Sue Co...

The physiopathology of malaria, one of the most deadly human parasitic diseases worldwide, is complex, as it is a systemic disease involving multiple parasitic stages and hosts and leads to the activation of numerous immune cells and release of inflammatory mediators. While some cytokines increased in the blood of patients infected with Plasmodium falciparum have been extensively studied, others, such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3), have not received much attention. GM-CSF and IL-3 belong to the β common (βc/CD131) chain family of cytokines, which exhibit ple...

AbstractPurpose of ReviewThe purpose of this review is to discuss the current knowledge of HIV and tissue parasite co-infection in the context of transmission enhancement, clinical characteristics, treatment, relapse, and clinical outcomes.Recent FindingsThe pathophysiology and clinical sequelae of tissue parasites in people living with HIV (PLWH) have been well described for only a handful of organisms, primarily protozoa such as malaria and leishmaniasis. Available published data indicate that the interactions between HIV and tissue parasites are highly variable depending on the infecting organism and the degree of host ...

ConclusionThese results indicate that A. farnesiana pods contain nematocidal compounds and might be promising natural anthelmintic agents against H. contortus. This leguminous plant could be used as a nutraceutical food source for the control of gastrointestinal nematodes in small ruminants.Graphical abstract

L ópez-Uribe, Jun Miao, Liwang CuiPlasmodium ovale accounts for a disproportionate number of travel-related malaria cases. This parasite is understudied since there is a reliance on clinical samples. We collected aP.ovale curtisi parasite isolate from a clinical case in western Thailand and performed RNA-seq analysis on the blood stage transcriptomes. Using bothde novo assembly and alignment-based methods, we detected the transcripts for 6628 out of 7280 annotated genes. For those lacking evidence of exp...

(University of Bern) An international scientific consortium led by the cell biologists Volker Heussler from the University of Bern and Oliver Billker from the Ume å University in Sweden has for the first time systematically investigated the genome of the malaria parasite Plasmodium throughout its life cycle in a large-scale experiment. The researchers were able to identify hundreds of targets that are urgently needed in drug and vaccine development to eradicate the disease.

The objective of this study was to evaluate the in vitro antiplasmodial properties against malaria parasite in 15 plants mentioned in Indian traditional medicine texts.MethodsIn vitro antiplasmodial activity of methanolic extracts obtained from Indian traditional medicinal plants was evaluated on Plasmodium falciparum of FCK2 and INDO strains using schizont maturation inhibition assay and parasite lactate dehydrogenase inhibition assay.ResultsMethanolic extracts of Adhatoda zeylanica, Embelia ribes, Piper nigrum and Plumbago zeylanica exhibited more than 50% inhibition in both the stains in schizont maturation inhibition a...
