Effects of UVC doses on the removal of antimicrobial resistance elements from secondary treated sewage.

Wastewater treatment plants (WWTPs) currently face major challenges toward the removal of microcontaminants and/or microbial matrices and consequently play an important role in the potential dissemination of biological resistance in freshwater. The ultraviolet (UV) system is a tertiary treatment strategy increasingly applied worldwide, although many studies have shown that disinfected effluent can still contain antibiotic-resistant bacteria and resistance genes. Therefore, to better understand the effects of UV radiation doses on the removal of all resistance elements (antibiotics, antibiotic-resistant bacteria, and antibiotic resistance genes), the present study was designed using a pilot-scale photoreactor.

Cockroaches are widely recognized as vectors for transmitting pathogenic microorganisms in hospital and community environments due to their movement between contaminated and human-occupied spaces. (. ), particularly methicillin-resistant (MRSA), is a primary global health concern because of its capacity to cause a wide range of infections and its resistance to many antibiotics.

Background: Pneumocystis jirovecii colonization rates in healthy patients are unclear. Previously published studies suggest that the fungus could play a role in the physiopathology and progression of chronic respiratory diseases.
Aims: The goal of this study was to determine the prevalence of colonization by this fungus in the lower respiratory tract of immunocompetent patients who are not at risk of dysbiosis.
Background: Uzbekistan, a highly endemic country for hepatitis B virus (HBV), introduced infant vaccination with hepatitis B vaccine (HepB) in 2001. Since 2002, it had ≥90 % reported immunization coverage for ≥3 doses of HepB (HepB3) and the birth dose (HepB-BD). However, the impact of HepB vaccination and the progress towards achieving the regional hepatitis B control and global viral hepatitis B elimination goals had not been assessed.

Genetic polymorphism of the dihydropyrimidine dehydrogenase gene () is responsible for the variability found in the metabolism of fluoropyrimidines such as 5-fluorouracil (5-FU), capecitabine, or tegafur. The genotype is linked to variability in enzyme activity, 5-FU elimination, and toxicity. Approximately 10-40% of patients treated with fluoropyrimidines develop severe toxicity.
