Wastewater surveillance of SARS-CoV-2 genomic populations on a country-wide scale through targeted sequencing.

SARS-CoV-2 surveillance of viral populations in wastewater samples is recognized as a useful tool for monitoring epidemic waves and boosting health preparedness. Next generation sequencing of viral RNA isolated from wastewater is a convenient and cost-effective strategy to understand the molecular epidemiology of SARS-CoV-2 and provide insights on the population dynamics of viral variants at the community level. However, in low- and middle-income countries, isolated groups have performed wastewater monitoring and data has not been extensively shared in the scientific community.

Multiple forms of hotspots of tetrapod biodiversity and the challenges of open-access data scarcity.

The uneven spatial distribution of biodiversity is a defining feature of nature. In fact, the implementation of conservation actions both locally and globally has progressively been guided by the identification of biodiversity 'hotspots' (areas with exceptional biodiversity). However, different regions of the world differ drastically in the availability of fine-scale data on the diversity and distribution of species, thus limiting the potential to assess their local environmental priorities.

[Active surveillance of febrile seizures associated to DPT vaccines in a sentinel hospital in Uruguay].

Background: Febrile seizures are VAERS often associated with whole-cells Diphtheria-Pertussis-Tetanus vaccines.

Aim: To analyze the association of febrile seizures with the administration of pentavalent vaccine in children under two-years-old assisted in the Centro Hospitalario Pereira Rossell (CHPR), in Montevideo during 2014.

Methods: Self-controlled case series study.

Biodiversidata: An Open-Access Biodiversity Database for Uruguay.

Background: The continental and marine territories of Uruguay are characterised by a rich convergence of multiple biogeographic ecoregions of the Neotropics, making this country a peculiar biodiversity spot. However, despite the biological significance of Uruguay for the South American subcontinent, the distribution of biodiversity patterns in this country remain poorly understood, given the severe gaps in available records of geographic species distributions. Currently, national biodiversity datasets are not openly available and, thus, a dominant proportion of the primary biodiversity data produced by researchers and institutions across Uruguay remains highly dispersed and difficult to access for the wider scientific and environmental community.

Leukocyte Profiles Reflect Geographic Range Limits in a Widespread Neotropical Bat.

Quantifying how the environment shapes host immune defense is important for understanding which wild populations may be more susceptible or resistant to pathogens. Spatial variation in parasite risk, food and predator abundance, and abiotic conditions can each affect immunity, and these factors can also manifest at both local and biogeographic scales. Yet identifying predictors and the spatial scale of their effects is limited by the rarity of studies that measure immunity across many populations of broadly distributed species.

High frequency and extensive genetic heterogeneity of TTSuV1 and TTSuVk2a in PCV2- infected and non-infected domestic pigs and wild boars from Uruguay.

Torque teno sus virus (TTSuV) infection is common worldwide in both healthy and diseased swine and a relationship between this virus and a particular disease in pigs has not been established. This work aimed to investigate the presence of TTSuV1 and TTSuVk2a in Porcine Circovirus type 2 (PCV2)-infected and non-infected domestic pigs and free-living wild boars from Uruguay. Our data evidenced a high frequency of detection and a wide circulation of TTSuV among pig herds and wild boar populations.
