Multivariate statistical analysis of surface water quality in the capibaribe river (Pernambuco state, Northeast Brazil): Contributions to water management.

Assessing the quality of surface waters is essential for identifying changes in freshwater ecosystems and supporting the planning/proposing of measures to mitigate polluting sources. However, many studies involving the identification of pathogenic bacteria and/or their resistance profile to antimicrobial agents need a more holistic approach to conditioning or modulating factors. Thus, we apply different multivariate statistical techniques to the data set from the Capibaribe River's surface water, one of the most important in the Northeast of Brazil.

Investigation of factors related to biofilm formation in Providencia stuartii.

Providencia stuartii is one of the Enterobacteriaceae species of medical importance commonly associated with urinary infections, which can also cause other ones, including uncommon ones, such as liver abscess and septic vasculitis. This bacterium stands out in the expression of intrinsic and acquired resistance to antimicrobials. Besides, it uses mechanisms such as biofilm for its persistence in biotic and abiotic environments.

Effects of Cefazolin and Meropenem in Eradication Biofilms of Clinical and Environmental Isolates of Proteus mirabilis.

Proteus mirabilis is an opportunistic Gram-negative bacterium belonging to the family Enterobacteriaceae and is known for its ability to cause urinary tract infections. The aim of this study was to determine the value of the minimum concentration of cefazolin and meropenem on biofilm eradication, as well as the resistance profiles and genetic diversity of clinical and environmental isolates of P. mirabilis.

Occurrence and Diversity of Intra- and Interhospital Drug-Resistant and Biofilm-Forming and .

and are the most relevant Gram-negative bacteria associated with hospital and opportunistic infections. This study aimed to evaluate the dynamics of drug-resistant . and .

In vitro evaluation of mercury (Hg) effects on biofilm formation by clinical and environmental isolates of Klebsiella pneumoniae.

The increase in urbanization and industrialization has contributed to the contamination of different environments by means of xenobiotic compounds, such as heavy metals, causing changes in microbial communities. Among these metals, the Mercury (Hg) is one the most prevalent toxic metals for the environment The present study aimed to evaluate the effect of mercury on the formation of biofilm by environmental (collected from urban stream water) and clinical isolates of Klebsiella pneumoniae. In addition, antibiotic resistance, virulence factors, and genetic diversity were investigated.
