ENDS consumption in students of higher education: Phenomenon on the rise during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic triggered transformations in the population's lifestyles, including electronic nicotine delivery system (ENDS) consumption. The aim of the study was to determine associations between ENDS consumption habits and lifestyles among higher education students in Bogotá, Colombia.

Methods: This study employed a cross-sectional analytical design, based on a self-administered online survey, conducted in 2021, among students aged 18-59 years.

Salmonella prevalence and characterization in a free-range pig processing plant: tracking in trucks, lairage, slaughter line and quartering.

New consumer tendencies are focused on products derived from systems which allow both a high animal welfare condition and a high food safety level. However, sometimes animal welfare regulations make the adoption of adequate bio-security measures difficult, representing a barrier for animal health and food safety. Thus the aim of this study was to determine the prevalence of Salmonella at different points of the pig slaughtering process (Trucks, Lairage, Slaughter line and Quartering, TLSQ) from pigs reared in free-range systems.

Susceptibility trends of Bacteroides fragilis group and characterisation of carbapenemase-producing strains by automated REP-PCR and MALDI TOF.

Susceptibility testing of clinical isolates of anaerobic bacteria is not considered, often, mandatory in routine clinical practice and the treatments are empirically established. Thus, periodic monitoring of the susceptibility patterns of anaerobic bacteria is advisable. The aim of this study was to update on resistance of Bacteroides fragilis group in our Institution with special attention to carbapenems reporting metallo-beta-lactamase producing strains for the first time in Spain, and to compare fingerprinting analysis results obtained by using automated rep-PCR (DiversiLab System) and MALDI-TOF MS.

Prevalence and antimicrobial susceptibility of Salmonella infections in free-range pigs.

The prevalence of Salmonella spp. infection was determined in 67 free-range pig herds in southern Spain. Microbiological assessment was performed on ileocolic lymph nodes collected at slaughter according to ISO 6579:2002 procedures.
