Age influences thermal tolerance in Asian malaria mosquito

Donna Huber on August 11, 2020

Environmental portrait of Courtney Murdock in her laboratory at UGA's School of Veterinary Medicine (Dorothy Kozlowski) Malaria disease transmission models are important tools for controlling and eliminating disease spread. However, a model is only as good as the assumptions about the various variables. Dr. Courtney Murdock, a member of the UGA’s Center for Tropical and …

NIH awards CTEGD $1.9 million to support training in tropical and emerging global diseases

Donna Huber on August 6, 2020

UGA’s Center for Tropical and Emerging Global Diseases has been awarded $1.9 million from the National Institutes of Health to continue its pre- and post-doctoral training program for the next five years. First funded in 2004, CTEGD has received nearly $2 million from NIH to train the next generation of scientists in the fight against …

Metabolomics profiling reveals new aspects of dolichol biosynthesis in Plasmodium falciparum

Donna Huber on August 6, 2020

The cis-polyisoprenoid lipids namely polyprenols, dolichols and their derivatives are linear polymers of several isoprene units. In eukaryotes, polyprenols and dolichols are synthesized as a mixture of four or more homologues of different length with one or two predominant species with sizes varying among organisms. Interestingly, co-occurrence of polyprenols and dolichols, i.e. detection of a …

Age influences the thermal suitability of Plasmodium falciparum transmission in the Asian malaria vector Anopheles stephensi

Donna Huber on July 22, 2020

Models predicting disease transmission are vital tools for long-term planning of malaria reduction efforts, particularly for mitigating impacts of climate change. We compared temperature-dependent malaria transmission models when mosquito life-history traits were estimated from a truncated portion of the lifespan (a common practice) versus traits measured across the full lifespan. We conducted an experiment on …

Pre-Erythrocytic Vaccines against Malaria

Donna Huber on July 21, 2020

Malaria, caused by the protozoan Plasmodium, is a devastating disease with over 200 million new cases reported globally every year. Although immunization is arguably the best strategy to eliminate malaria, despite decades of research in this area we do not have an effective, clinically approved antimalarial vaccine. The current impetus in the field is to develop vaccines …

Test, Treat, Track, Test, and Treat Active Surveillance toward Elimination of Schistosomiasis: A Feasibility Study

Donna Huber on July 13, 2020

We assessed the feasibility of using a test, treat, track, test, and treat (5T) active surveillance strategy to identify and treat individuals with schistosomiasis in three very low-prevalence villages in Kafr El Sheikh Governorate, Egypt. Primary index cases (PICs) were identified using the point-of-care circulating cathodic antigen (POC-CCA) assay in schools, in rural health units …

SCORE – a decade of operational research with a lasting legacy

Donna Huber on July 10, 2020

It all began with a simple phone call and now, more than a decade later, the Schistosomiasis Consortium for Operational Control and Evaluation (SCORE) is preparing to pass the baton to new groups of investigators working on understanding and controlling schistosomiasis. Under the direction of Dan Colley, a member of the Center for Tropical and …

Flavanones From the Twigs and Barks of Artocarpus Lakoocha Having Antiplasmodial and Anti-TB Activities

Donna Huber on July 1, 2020

Chromatographic separation of the acetone extracts from the twigs and barks of Artocarpus lakoocha led to the isolation of the one new flavanone, lakoochanone (1), together with eleven known compounds (2-12). Lakoochanone (1) and moracin C (4) exhibited weak antiplasmodial activity against Plasmodium falciparum Dd2 with IC50 values of 36.7 and 33.9 µM, respectively. Moreover, moracin …
