Article Synopsis
  • - Bats serve as hosts for numerous pathogens including viruses, bacteria, fungi, and more, which can infect other animals and humans.
  • - This study used advanced sequencing methods to analyze microbial communities found in blood, feces, and oral swabs from two bat genera in eastern Colombia, finding a rich diversity of microorganisms.
  • - Results showed that microbial compositions varied by bat genus and body fluid, indicating potential interactions and movements of these microbes within the bats, while also revealing some pathogens that could pose risks to public health.

Chagas disease affects millions of people in Colombia and worldwide, with its transmission influenced by ecological, environmental, and anthropogenic factors. There is a notable correlation between vector transmission cycles and the habitats of insect vectors of the parasite. However, the scale at which these cycles operate remains uncertain.

Background: Chagas disease, affecting approximately eight million individuals in tropical regions, is primarily transmitted by vectors. Rhodnius prolixus, a triatomine vector, commonly inhabits in ecotopes with diverse palm tree species, creating optimal conditions for vector proliferation. This study aims to explore the transmission ecology of Trypanosoma cruzi, the causative parasite of Chagas disease, by investigating the feeding patterns and natural infection rates of R.

Article Synopsis
  • Livestock is key for food security and the economy, but viral infections can harm cattle health and pose risks to human and animal health, making virus identification critical for prevention and control.
  • The study focused on characterizing viral communities in cattle fecal samples from Ubaté Province, Colombia, using advanced metagenomic sequencing techniques.
  • Findings showed a stable viral composition dominated by Picornaviridae family members, with significant discoveries of viruses like Enterovirus E and Bovine Astrovirus, marking the first report of certain veterinary-important viruses in Colombia.

A comprehensive understanding of the virome in mosquito vectors is crucial for assessing the potential transmission of viral agents, designing effective vector control strategies, and advancing our knowledge of insect-specific viruses (ISVs). In this study, we utilized Oxford Nanopore Technologies metagenomics to characterize the virome of mosquitoes collected in various regions of Colombia, a country hyperendemic for dengue virus (DENV). Analyses were conducted on groups of insects with previous natural DENV infection (DENV-1 and DENV-2 serotypes), as well as mosquito samples that tested negative for virus infection (DENV-negative).

Mosquitoes (Diptera: Culicidae) are primary vectors of arthropod-borne viruses (arboviruses) that pose significant public health threats. Recent advances in sequencing technology emphasize the importance of understanding the arboviruses and insect-specific viruses (ISVs) hosted by mosquitoes, collectively called the "virome". Colombia, a tropical country with favorable conditions for the development and adaptation of multiple species of Culicidae, offers a favorable scenario for the transmission of epidemiologically important arboviruses.

Tick-borne diseases have increased significantly in Europe and Spain in recent years. One strategy explored for tick surveillance and control is the study of the microbiota. The focus is on understanding the relationships between pathogens and endosymbionts within the microbiota and how these relationships can alter these arthropods' vectorial capacity.

Background: There has been a long-standing debate over the taxonomic status of Rhipicephalus sanguineus sensu lato. Different studies worldwide have reported the occurrence of different well-defined lineages, in addition to Rhipicephalus sanguineus sensu stricto. To date, there are very few studies examining the diverse aspects of this tick in Colombia.
