Molecular analysis of influenza A(H3N2) in a remote tropical island during 2014-2019 to identify the frequency of introduction and local circulation.

Background: The sources of new antigenic Influenza A(H3N2) variants and the role of tropical regions in the global A(H3N2) circulation remain unclear. By conducting molecular analysis, this study aimed to identify A(H3N2) introduction events and the duration of local circulation in a geographically remote tropical island.

Methods: Nasopharyngeal/nasal samples were collected from symptomatic children under five years old in a remote tropical island of the Philippines between 2014-2019.

Characterization and Identification of and Causing Root Necrosis and Wilting of Orange Trees in Chile.

Orange trees ( × (L.) Osbeck) are the third-most cultivated citrus fruit species in Chile. In recent years, several trees in three orange orchards of 'Lane late' and 'Fukumoto' cultivars grafted on 'Robidoux' trifoliate orange ( (L.

Antimicrobial Residues in Poultry Litter: Assessing the Association of Antimicrobial Persistence with Resistant Strains.

: We set out to evaluate the persistence of sulfachloropyridazine, oxytetracycline, and enrofloxacin in broiler chicken litter following therapeutic oral treatment and its association with the isolation of resistant to these antimicrobials. : Forty broiler chickens were raised under controlled conditions and divided into three experimental groups, each treated with a different antimicrobial, in addition to an untreated/control group. Litter samples were collected post treatment, analyzed by UPLC-MS/MS, and processed for the isolation of .

Cardio-Obstetrics Practice in Latin America: A Regional Survey of General Cardiologists.

Background: Cardiovascular (CV) disease is a leading cause of death in pregnant women globally, especially in low- and middle-income countries including Latin America (LATAM), where there is lack of data on how cardiologists are trained in cardio-obstetrics (CO) and the practice patterns in the care of pregnant patients.

Objectives: The authors aimed to identify CO competency and practice patterns among LATAM general cardiologists.

Methods: An anonymous cross-sectional Google-based electronic survey was sent via email to clinical cardiologists through local American College of Cardiology chapters and CV societies.

Aquatic animal health: history, present and future.

Aquaculture stands as the fastest-growing food fish sector, expected to satisfy global demand for aquatic products. However, its expansion has led to disease emergence, adversely affecting both production and biodiversity. In response, since the mid-1990s the World Organisation for Animal Health (WOAH) has developed initiatives, notably the Aquatic Animal Health Code and the Manual of Diagnostic Tests for Aquatic Animals, aimed at harmonising health standards for international trade in aquatic animals.
