Bat coronavirus surveillance across different habitats in Yucatán, México.

Bats, which play a vital role in maintaining ecosystems, are also known as natural reservoirs of coronaviruses (CoVs), thus have raised concerns about their potential transmission to humans, particularly in light of the emergence of MERS-CoV, SARS-CoV, and SARS-CoV-2. The increasing impact of human activities and ecosystem modifications is reshaping bat community structure and ecology, heightening the risk of the emergence of potential epidemics. Therefore, continuous monitoring of these viruses in bats is necessary.

Isolation and characterization of porcine epidemic diarrhea virus associated with the 2014 disease outbreak in Mexico: case report.

Background: Interest in porcine epidemic diarrhea has grown since the 2013 outbreak in the United States caused major losses, with mortality rates up to 100 % in suckling piglets. In Mexico, an outbreak of porcine epidemic diarrhea, characterized by 100 % mortality in piglets, began in March 2014 in the State of Mexico.

Methods: The aim of this study was to confirm and identify porcine epidemic diarrhea virus (PEDV) in samples from piglets with suggestive clinical signs using virological, histological, and molecular techniques.
