The factors influencing dengue transmission by the Aedes aegypti mosquito vector within the region can be classified as ecological, biological, and social determinants. In this review, we summarized the published literature on the evidence for the determinants of dengue vector dynamics, transmission, and epidemiological outcomes in LAC. We searched PubMed, SCOPUS, and LILACS databases in September 2022 to collect published works irrespective of study design published in either English, French, Portuguese, or Spanish. Full-text articles were obtained for the studies that passed the title and abstract screening process. During full-text screening, articles were assessed to determine if they met the eligibility criteria. Data were extracted using NVivo™ 12. Data were organized as NVivo codes. Themes were compiled and communicated narratively. We included 90 peer-reviewed research articles from LAC between 2007 and 2022. The included studies were from 15 different countries, dependencies, and territories in the region. Several dengue-related indicators and outcomes were classified as ecological, biological, or social. Eight main factors were found, including: micro- and macro-climatic factors; entomological and pathogenic factors; and global-, community-, household-, and individual- level social factors. We identified several existing knowledge gaps in the literature. Making salient these gaps may serve as a starting point for future vector-borne infectious disease research to equip policymakers and public health practitioners to develop effective strategies to mitigate the impact of dengue and protect vulnerable populations in LAC.</p>","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143732806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recorded the H/L ratio of 723 birds of 10 species captured in Brasília (a large city in central Brazil), as a measure of chronic stress in birds. The H/L ratio was positively associated with the intensity of urbanization and negatively associated with body condition. However, body condition was not associated with intensity of urbanization. We confirmed our hypothesis that birds living in areas with greater urban intensity are more stressed. In addition, we demonstrated that the H/L ratio is negatively associated with body condition, and that this variable should be considered in studies that aim to assess the health of animals.

Understanding factors contributing to rodent hantavirus transmission is crucial for assessing and predicting human hantavirus pulmonary syndrome risk. Infection dynamics are often studied using seroprevalence time series from serological tests, but this method only provides an average consequence over time, offering limited insight into timing or mechanisms. To overcome this, we developed a strategy which combines capture-mark-recapture data and longitudinal serological data in order to determine the likely time window for infection and correlate it with individual features (sex and age) and the weather conditions to which each individual rodent was subject throughout its lifetime. We applied our seroconversion model to field data from two sigmodontine species, Akodon azarae and Oligoryzomys flavescens, collected in agroecosystems in the Buenos Aires province of Argentina, from May 2014 to January 2016, with a trapping effort of 19,800 trap-nights. By using daily time series, we found different weather conditions related to high seroconversion rates for each species, hardly identifiable in seroprevalence data. Higher infection rates in males and the fact that strongest effects on seroconversion converge at the time of the year that corresponds to the reproductive period indicate that transmission may be connected to matting behavior. In addition, by comparing weather conditions that relate to seroconversion with those which favor virus persistence in the environment, we argue that nesting habits could also play a role in hantavirus transmission.</p>","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143712041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there have been some concerns about the quality of such data, and the reliability and sustainability of such means of conducting surveillance. Virological screening allowed us to identify 6.2% (17/274) of the tested mosquito pools as positive for either snowshoe hare virus (SHV, 14 pools) or Jamestown Canyon virus (JCV)-like viruses (3 pools). Additionally, we found evidence of clear geographic patterns in SHV circulation and identified a novel and likely reassortant JCV-like virus.

This study aimed to analyze antimicrobial resistance and biofilm formation in GNB isolated from cockroaches collected in the hospital environment. Cockroaches were collected, and bacterial isolation was performed from their gut contents and external surfaces. GNB strains were tested for antibiotic susceptibility using the disk diffusion method and examined for Extended-spectrum β-lactamases (ESBLs) and carbapenemases production. Molecular characterization of ESBLs and carbapenemases in GNB involved PCR amplification of antibiotic resistance genes, while biofilm formation was studied using a microplate assay. Seventy-five cockroaches were collected from which 165 GNB were isolated. The prevalence of ESBL-producing and carbapenemase-producing GNB was 6.7 and 1.8%, respectively. The predominant ESBL gene was bla_CTX-M-28, while bla_NDM-1 was the only carbapenemase gene detected. The qnrS1 gene was found in one NDM-1-producing Klebsiella pneumoniae and three ESBL-producing Escherichia coli. The qacΔE1 gene was detected in an NDM-1-producing Citrobacter freundii and a CTX-M-28-producing E. coli, whereas one NDM-1-producing Enterobacter cloacae carried both qacΔE1 and acrA genes. Strains harboring qacΔE1 and/or acrA genes exhibited biofilm-forming capabilities, with biofilm formation observed in 81.81% of ESBL-producing isolates and 100% of carbapenemase-producing isolates. The study underscores the role of cockroaches in carrying and disseminating ESBL- and carbapenemase-producing GNB in hospital settings. The coexistence of disinfectant resistance genes and antibiotic resistance suggests co-selection mechanisms, while biofilm formation enhances bacterial survival.

Of particular concern is avian influenza virus (AIV), which in its low-pathogenic form is endemic in many wild bird populations, notably waterfowl and shorebirds, and in its high-pathogenic form poses a threat to wildlife, livestock and people. Many pollutants have immunomodulative properties, yet little is known about how these pollutants affect AIV infection risk specifically. We examined concentrations of known immunomodulatory compounds, per- and polyfluoroalkyl substances (PFASs), and assessed their influence on AIV infection in three reservoir species, red-necked stint (Calidris ruficollis, n = 121), pacific black duck (Anas superciliosa, n = 57) and grey teal (Anas gracilis, n = 62). Using data on viral prevalence (cloacal/oropharyngeal swabs) and seroprevalence (AIV anti-nucleoprotein antibodies), we found no significant effect of PFASs pollution (total PFASs < 0.01-470 ng/g in red-necked stint, < 0.01-600 ng/g in pacific black duck and 0.3-200 ng/g in grey teal) on infection status in our three species.

While Bd has been near globally distributed for decades, Bsal is a more recently emerged pathogen, having been identified just over a decade ago with current impacts localized to salamandrids in parts of Europe. However, because there is concern that Bsal will cause widespread declines if introduced to naïve regions-such as the Americas where the greatest diversity of salamandrids exist-it is imperative that widespread monitoring strategies be implemented to mitigate the spread of Bsal.
