Bullfrogs (Lithobates catesbeianus) as a Potential Source of Foodborne Disease.

In Mexico, bullfrogs (Lithobates catesbeianus) are produced as gourmet food. However, bullfrogs can be carriers of pathogens because the frogs' preferred living conditions occur in stagnant water. The present study aimed to identify bacteria that cause foodborne diseases or are associated with human diseases.

Prevalence of Parasitic Infections with Zoonotic Potential in Tilapia: A Systematic Review and Meta-Analysis.

Tilapia has a high socioeconomic value in many countries worldwide. However, it has been identified as a zoonotic parasite reservoir. A systematic literature search and meta-analysis were carried out in order to estimate the global prevalence of zoonotic parasites that affect tilapia.

Challenges in the Detection of SARS-CoV-2: Evolution of the Lateral Flow Immunoassay as a Valuable Tool for Viral Diagnosis.

SARS-CoV-2 is an emerging infectious disease of zoonotic origin that caused the coronavirus disease in late 2019 and triggered a pandemic that has severely affected human health and caused millions of deaths. Early and massive diagnosis of SARS-CoV-2 infected patients is the key to preventing the spread of the virus and controlling the outbreak. Lateral flow immunoassays (LFIA) are the simplest biosensors.

Kinetics of Eosinophils during Development of the Cellular Infiltrate Surrounding the Nurse Cell of in Experimentally Infected Mice.

We study the kinetics of eosinophils during the development of the cellular infiltrate surrounding the nurse cell of () in experimentally infected mice. Male CD1 mice were experimentally infected with 50 viable muscle larvae of the MSUS/MEX/91/CM-91 strain. Tongues and diaphragms were obtained daily from days 13 to 39 post infection.

Genera and Species of the Anisakidae Family and Their Geographical Distribution.

Nematodes of the Anisakidae family have the ability to infest a wide variety of aquatic hosts during the development of their larval stages, mainly marine mammals, aquatic birds, such as pelicans, and freshwater fish, such crucian carp, these being the hosts where the life cycle is completed. The participation of intermediate hosts such as cephalopods, shrimp, crustaceans and marine fish, is an important part of this cycle. Due to morphological changes and updates to the genetic information of the different members of the family, the purpose of this review was to carry out a bibliographic search of the genus and species of the Anisakidae family identified by molecular tests, as well as the geographical area in which they were collected.

Molecular Identification and Virulence Potential of the Genus Isolated from Wild Rainbow Trout () in Mexico.

The members of the genus are important foodborne pathogens, with a worldwide distribution. Wild rainbow trout, from the national protected area Santuario del Agua State Park, Corral de Piedra, were analyzed. Species of were isolated from the trout, and their pathogenic potential was analyzed based on different pathogenicity and virulence factors.

Genetic characterization of Escherichia coli isolated from cattle carcasses and feces in Mexico state.

Meat of bovine origin is one of the major vehicles in the transmission of verotoxigenic Escherichia coli (VTEC) to human consumers. This pathogen can produce serious human illness, including bloody diarrhea and hemolytic uremic syndrome. The aim of the current study was to characterize E.

Phenotypic-genotypic resistance in Salmonella spp. isolated from cattle carcasses from the north central zone of the State of Mexico.

Salmonella is a public and animal health problem due to the generation of strains multiresistant to antimicrobial products. The objective of this study was to determine prevalence and antimicrobial phenotypic and genotypic resistance of Salmonella spp. isolated from beef cattle carcasses killed in slaughterhouses of the north central zone of the State of Mexico.
