The importance of bioactive compounds in agro-industrial by-products of plant origin lies in their direct impacts on human health. These compounds have been shown to possess antioxidant, anti-inflammatory, and antimicrobial properties, contributing to disease prevention and strengthening the immune system. In particular, the antimicrobial action of these compounds emerges as an important tool in food preservation, providing natural alternatives to synthetic preservatives and contributing to combating antimicrobial resistance.

UPEC is part of the extraintestinal pathogenic (ExPEC), but hybrid strains possessing both diarrheagenic (DEC) and ExPEC traits, termed "hypervirulent", present a significant health threat. This study assessed the prevalence of UPEC PAIs, ExPEC sequence types (ST), DEC genes, carbapenemase and extended-spectrum β-lactamase (ESBL) phenotypes, resistance genotypes, and plasmids in 40 clinical isolates of UPEC.

Recent reports have highlighted as an emerging pathogen harbouring virulence and resistance determinants. Little information exists on virulence and resistance determinants in strains isolated from environmental, food, and clinical samples.
View Article and Find Full Text PDFBackground: Urinary tract infections (UTI) are one of the most common pathologies in Mexico and the majority are caused by uropathogenic Escherichia coli (UPEC). UPEC possesses virulence and resistance determinants that promote UTI development and affect diagnosis and treatment. This study aims to systematically review published reports of virulence genes, antibiotic resistance, and phylogenetic groups prevalent in clinical isolates of UPEC in the Mexican population.

- Pathogenic strains of bacteria pose a significant public health threat due to their ability to resist antibiotics and their varying levels of virulence based on environmental factors and farming practices.
- A study was conducted in Hermosillo, Mexico, focusing on antibiotic resistance in bacteria isolated from Honeydew melon production, where 32 strains were collected from various sources including irrigation water and packaging workers.
- Results revealed alarming resistance levels, with 100% resistance to ertapenem and a high percentage showing multi-drug resistance, along with the discovery of certain antibiotic resistance genes, indicating a troubling prevalence of resistant bacteria in agricultural settings.
Article Synopsis
- The text discusses a significant bacterium found in both animal and human guts, which is crucial to the microbiome, highlighting its six pathogenic variants that cause diarrhea.
- A study revealed that out of 90 strains from healthy donors, over half had specific virulence markers associated with diarrheal pathotypes, including unique hybrids that combine features from multiple pathotypes.
- The research found that all strains were multidrug-resistant, with complete resistance to sulfonamides and aminoglycosides, lower resistance to other antibiotics, and proposed three new virotypes based on their virulence traits, particularly noting their strong ability to form biofilms.
Escherichia coli is among the most prevalent food contaminant microorganisms that have evolved, generating variants based on their effects on the host; these include commensals or pathobiont strains. The last classifications of E. coli intestinal pathobionts found in this review are enteroinvasive, enterohemorrhagic, enteropathogenic, enterotoxigenic, diffusely adherent, and enteroaggregative strains.

Background/purpose: Uropathogenic (UPEC) is the main cause of urinary tract infection (UTI) and it is known that pregnant women have a higher risk for UTI. UPEC has a variety of virulence and antibiotic resistance factors that facilitate its pathogenic success and it is crucial to know which are the susceptibility patterns, Extended-Spectrum-β-Lactamase (ESBL) production, virulence genes, pathogenicity islands (PAI), phylogenetic groups and serotypes among strains isolated from pregnant and non-pregnant women.
Methods: One hundred fifty UPEC strains were isolated from pregnant and non-pregnant women from two different Mexican states (Sonora and Puebla).
