Approaches to rapidly collecting global biodiversity data are increasingly important, but biodiversity blind spots persist. We organized a three-day Datathon event to improve the openness of local biodiversity data and facilitate data reuse by local researchers. The first Datathon, organized among microbial ecologists in Uruguay and Argentina assembled the largest microbiome dataset in the region to date and formed collaborative consortia for microbiome data synthesis.

Bacillus sensu lato were screened for their capacity to mineralize organic phosphorus (P) and promote plant growth, improving nitrogen (N) and P nutrition of soybean. Isolates were identified through Type Strain Genome Server (TYGS) and Average Nucleotide Identity (ANI). ILBB95, ILBB510 and ILBB592 were identified as Priestia megaterium, ILBB139 as Bacillus wiedmannii, ILBB44 as a member of a sister clade of B.

The New World screwworm, Cochliomyia hominivorax, is an obligate parasite, which is a major pest of livestock. While the sterile insect technique was used very successfully to eradicate C. hominivorax from North and Central America, more cost-effective genetic methods will likely be needed in South America.

Article Synopsis
  • Lutzomyia longipalpis is the primary sandfly vector for Leishmania infantum, which causes visceral leishmaniasis (VL) in the Americas, with a distribution from Mexico to Argentina and Uruguay.
  • The sandfly's genetic diversity and geographical structure have been influenced by past founder events during its spread across various biomes, notably recognized in Uruguay since 2010, when VL cases began to emerge.
  • Recent research has uncovered new mitochondrial DNA haplotypes in L. longipalpis collected in Uruguay, showing close genetic ties to populations in neighboring regions, suggesting their arrival may have been facilitated by environmental factors like forest corridors along the Uruguay River.

In a previous study, we evaluated the degree of virulence of Mycobacterium avium subsp. paratuberculosis (Map) strains isolated from cattle in Argentina in a murine model. This assay allowed us to differentiate between high-virulent MapARG1347 and low-virulent MapARG1543 strains.
