Ever since antimicrobial activity was observed at the end of the XIX century and antibiotics were produced on a large scale in the 40s, microorganisms have developed multiple resistance mechanisms, making treatment of infectious diseases difficult. For instance, several Gram-positive and Gram-negative bacteria lowered their sensitivity to ß-Lactam antibiotics as a result of their inadequate use and abuse. For this reason, microbial resistance to these drugs represents an increasing health problem in Latin America due to the emergence of drug-resistant bacterial strains. This review aims to summarize and analyze scientific literature reporting resistance to ß-lactam antibiotics in Latin America. We compiled scientific papers published during the last five years from PubMed, SciELO, and LILACS-BIREME. We found that: (i) it is common to identify resistance genes for ß-lactams in the soil and animal farms, and (ii) over 40% of strains isolated from clinical samples developed resistance against ß-lactam antibiotics.

Unregulated pig farming practices expose pigs to fecal sewage and antibiotic stress, which are common health risk factors. Thus, its effects on the animals' intestinal microflora were investigated herein. In total, 2,315,563 high-quality sequences were obtained via amplitude sequencing and, after OUT clustering, the fecal sewage group was identified to have the highest number and the antibiotic exposure group the lowest.

In agricultural production systems, the harm of both antibiotics and microplastics (MPs) to human health has been an important and continuously concerned issue. A small bagged silage production system was designed to investigate the effects of Lactoplantibacillus plantarum, polyethylene (PE) -MPs and their mixture on the silage fermentation and chemical composition of Tetracycline (TET) -contaminated whole plant maize. In addition, the bacterial community of silage samples was analyzed by using next generation genome sequencing technology.

Non-antibiotic pollutants have been identified as contributors to the development of antibiotic resistance across various environments. Wastewater treatment plants, recognized as hotspots for antibiotic resistance genes (ARGs), have received extensive attention regarding the mechanisms driving resistance changes in activated sludge. However, the specific impacts of heavy metals and aromatic organics-common pollutants in industrial wastewater-on the resistome of activated sludge, as well as the underlying mechanisms driving these effects, remain underexplored.
