Geography, Antimicrobial Resistance, and Genomics of (Serotypes Newport and Anatum) from Meat in Mexico (2021-2023).

non-typhoidal is a major contributor to diarrheal diseases, with over 2600 serovars identified across diverse environments. In Mexico, serovars Newport and Anatum have shown a marked increase, especially in foodborne disease, posing a public health problem. We conducted a cross-sectional study from 2021 to 2023 using active epidemiological surveillance to assess contamination in ground beef and pork at butcher shops nationwide.

A microfluidic card-based electrochemical assay for the detection of sulfonamide resistance genes.

Most electroanalytical detection schemes for DNA markers require considerable time and effort from expert personnel to thoroughly follow the analysis and obtain reliable outcomes. This work aims to present an electrochemical assay performed inside a small card-based platform powered by microfluidic manipulation, requiring minimal human intervention and consumables. The assay couples a sample/signal dual amplification and DNA-modified magnetic particles for the detection of DNA amplification products.

Determination of Glyphosate in Water from a Rural Locality in México and Its Implications for the Population Based on Water Consumption and Use Habits.

Glyphosate is a broad-spectrum herbicide widely used worldwide. Indeed, it is the herbicide most applied to all Mexican crops. Due to the overuse and poor disposal of the waste, this herbicide can reach the aquatic environments such as groundwater and surface water.

Trends and Perspectives in Immunosensors for Determination of Currently-Used Pesticides: The Case of Glyphosate, Organophosphates, and Neonicotinoids.

Pesticides, due to their intensive use and their peculiar chemical features, can persist in the environment and enter the trophic chain, thus representing an environmental risk for the ecosystems and human health. Although there are several robust and reliable standard analytical techniques for their monitoring, the high frequency of contamination caused by pesticides requires methods for massive monitoring campaigns that are capable of rapidly detecting these compounds in many samples of different origin. Immunosensors represent a potential tool for simple, rapid, and sensitive monitoring of pesticides.
