Article Synopsis
- The study examined the resistance and virulence profiles of Proteus mirabilis from patients at a hospital in Brazil between 2019 and 2022.
- There was a notable increase in antimicrobial resistance and multidrug-resistant strains during the pandemic period compared to pre-pandemic times.
- Patient demographics indicated that those hospitalized during the pandemic were older and had longer stays, suggesting a link between COVID-19 and rising antimicrobial resistance in this bacterium associated with UTIs and HAIs.
Article Synopsis
- * A pan-genomic approach was used to investigate if unique genes in a specific P. mirabilis strain (LBUEL-A33) contribute to avian cellulitis, revealing multiple unique genes but inconclusive links to their function in the disease.
- * The study suggests that multiple factors are needed for P. mirabilis to cause avian cellulitis and emphasizes the need for more research to comprehend the mechanisms involved for effective control and prevention strategies.
Water quality monitoring in southern Brazil and the assessment of risk factors related to contamination by coliforms and Escherichia coli.
J Water Health

The potability of water, including underground sources, is constantly affected by human activities. To assess water quality and water security in rural and urban areas of southern Brazil, a quantitative, retrospective analysis of water samples collected monthly by the Brazilian health authorities (19,687 samples from 2013 to 2021) was performed. In rural areas, 5,979 water samples (77.

Morganella morganii is a bacterium belonging to the normal intestinal microbiota and the environment; however, in immunocompromised individuals, this bacterium can become an opportunistic pathogen, causing a series of diseases, both in hospitals and in the community, being urinary tract infections more prevalent. Therefore, the objective of this study was to evaluate the prevalence, virulence profile, and resistance to antimicrobials and the clonal relationship of isolates of urinary tract infections (UTI) caused by M. morganii, both in the hospital environment and in the community of the municipality of Londrina-PR, in southern Brazil, in order to better understand the mechanisms for the establishment of the disease caused by this bacterium.
