Equus caballus papillomavirus type 2 (EcPV-2) has been recently associated with the development of genital squamous cell carcinomas in horses. Nevertheless, its circulation among healthy, asymptomatic horses remains poorly understood. This study aimed to investigate the presence of EcPV-2 DNA in asymptomatic horses submitted to necropsy in southern Brazil. A total of 54 horses without clinical or histological evidence of genit...

Coal is a major global energy resource, but its extraction raises significant environmental and health concerns. Mining activities release large amounts of particulate matter, including nanoparticles (NPs), into the environment. These NPs are hazardous due to their content of polycyclic aromatic hydrocarbons (PAHs), metals, oxides, and other compounds capable of disrupting cellular and molecular processes. This study evaluated...

The emergence of new viral strains has been frequently associated with the onset of outbreaks in different epidemiological settings. This study investigated an acute gastroenteritis (AGE) outbreak, which occurred at a university campus in southern Brazil, in 2024, affecting approximately 30–40% of undergraduate students, with over 400 reported cases. The objectives were to describe the epidemiological and molecular features of...

Karst water bodies are vital groundwater resources particularly vulnerable to pollution. Protecting their water quality requires documenting contaminants traditionally associated with anthropogenic activities (metals, nutrients, and fecal indicator bacteria) as well as emerging contaminants, such as antibiotic-resistant organisms (AROs) and perfluoroalkyl substances (PFAS). This study detected contaminants in karst-associated...

Numerous studies conducted on a variety of temporal and spatial scales around the world show that dipteran parasitoids can exert effective control over some insect pests. This paper provides an overview of major examples of successful classical and augmentative biological control initiatives, organized by major dipteran families which include parasitoid species (i.e., Tachinidae, Phoridae, Sarcophagidae, Cryptochetidae, Bombyl...
