Tag: Antigen testing training - Anopheles Database
Overview: SARS-CoV-2 antigen rapid diagnostic tests (Ag-RDT) are being used globally to test suspect COVID-19 cases in contexts where PCR diagnostic may not be available, often at subnational level.
This course aims to provide Ag-RDT users with an understanding of the theoretical and practical components of SARS-CoV-2 Ag-RDT testing. It does not intend to address the implementation of Ag-RDT testing across the diagnostic network. It targets personnel involved in SARS-CoV-2 testing, including healthcare workers, laboratory workers and public health officers.
Certificates: A Record of Achievement will be issued to participants who receive at least 80% on the post-test. Participants who receive a Record of Achievement can also download an Open Badge for this course
The Plasmodium life cycle within the mosquito involves the gamete, zygote, motile ookinete, and the oocyst stage that supports sporogony and sporozoite formation. We mapped the P. falciparum transcriptome as the parasite progresses through the oocyst stage of development on days 2, 4, 6, and 8 post-P. falciparum infectious blood meal.
Through these genomic studies, we identified 212 novel transmission stage biomarkers including genes that are developmentally expressed at a single time point and genes that are pan-developmentally expressed at all four time points in P. falciparum oocysts.
Validation of a small subset of genes at the transcriptional and translational level resulted in identification of a signature of genes/proteins that can detect parasites within the mosquito as early as day 2 post-infectious blood meal and can be used to distinguish early versus late stage P. falciparum oocyst development in the mosquito.
Currently, circumsporozoite protein (CSP), which is detectable only after day 7 post-infection, is the only marker used for detection of P. falciparum infection in mosquitoes.
Our results open the prospect to develop a non-CSP based detection assay for assessment of P. falciparum infection in mosquitoes and evaluate the effect of intervention measures on malaria transmission in an endemic setting.
