Article Synopsis
- The Brazilian merganser is a critically endangered bird species with fewer than 250 mature individuals left in the wild, primarily located in pristine freshwater habitats in Brazil.
- Extensive genetic research shows low genetic diversity and high inbreeding due to recent population declines linked to habitat loss.
- Urgent conservation efforts are needed, including careful genetic monitoring, to enhance management strategies and ensure the long-term survival of the species in its natural environment.
Article Synopsis
- - A study was conducted in Brumado, Bahia, Brazil, to examine Aedes aegypti larvae for the presence of dengue, zika, and chikungunya viruses using molecular biology techniques.
- - Out of 20 collected larvae, 25% tested positive for dengue, 15% for chikungunya, and 15% were found to have both viruses simultaneously.
- - This research represents the first documented case of coinfection with dengue and chikungunya viruses in Aedes aegypti larvae.
The outbreaks caused by the Aedes aegypti-transmitted dengue virus (DENV), zakat virus (ZIKV), and chikungunya virus (CHIKV) result in a significant impact to the health systems of tropical countries. Furthermore, the occurrence of patients coinfected by at least two of these arboviruses is an aggravating factor in that scenario. On this basis, surveillance tools such as the Rapid Index Survey for Aedes aegypti (LIRAa) are used to estimate vector infestation in order to improve the prediction of human outbreaks.
