Plasmodium vivax is the predominant malaria parasite in Latin America. Its colonization history in the region is rich and complex, and is still highly debated, especially about its origin(s). Our study employed cutting-edge population genomic techniques to analyze whole genome variation from 620 P.

Very few incidents of cheetahs scavenging have been reported, with no explanation given as to why it may occur. In this paper, we provide three more observations of cheetahs scavenging between 2019 and 2023 in three different protected areas in South Africa and Malawi.

- - Caliciviruses and astroviruses are major causes of non-bacterial foodborne illnesses and gastroenteritis in humans, with rodents being key hosts for these viruses and many zoonotic pathogens that can affect humans.
- - A study screened 245 rodent intestine samples for these viruses, finding no caliciviruses but detecting astroviruses in 18 samples, specifically from the Rattus rattus species.
- - Phylogenetic analysis revealed that the detected astroviruses are closely related to strains found in Gabon, Kenya, and Asia, indicating that transportation methods may promote the spread of these viruses through rodent populations.
Article Synopsis
- The study explores the need for non-invasive diagnostic methods for detecting malaria, as traditional blood sampling is invasive and challenging.
- Saliva and stool samples were examined to see if they could effectively contain detectable DNA from malaria infection, using tests like microscopy and nested PCR.
- Results showed that while blood samples had 100% detection of malaria DNA, saliva and stool samples were significantly less effective, indicating that they cannot replace blood tests for accurate malaria diagnosis.
