Prevalence and molecular characterization of carbapenem-resistant Enterobacterales in patients from a public referral hospital in a non-metropolitan region of Brazil during and post the SARS-CoV-2 pandemic.

Antimicrobial resistance (AMR) poses a global threat, with carbapenem-resistant Enterobacterales (CRE) representing a significant concern due to limited therapeutic options. This study investigated the prevalence of carbapenemase genes in CRE strains isolated from tracheal aspirates of patients at a Brazilian university hospital between January 2020 and August 2023. Bacterial identification was conducted using MALDI-TOF, while carbapenemase genes were detected by qPCR.

Impact of superimposed Clostridium difficile infection in Crohn's or ulcerative colitis flares in the outpatient setting.

Purpose: The prospective assessment of Clostridium difficile infection (CDI) impact in inflammatory bowel disease (IBD) flare in outpatient setting has been poorly investigated. We aimed to evaluate the prevalence and the associated factors with CDI in IBD outpatients presenting colitis flares as well as the outcomes following treatment.

Methods: In this prospective cohort study, conducted from October, 2014, to July, 2016, 120 IBD patients (55% presenting colitis flare) and 40 non-IBD controls were assessed for CDI.

Detection and Characterization of and Methicillin-Resistant in Foods Confiscated in EU Borders.

The aim of the study was to evaluate the potential role of the illegal entry of food in UE in the Methicillin-resistant (MRSA) spread. We studied the prevalence and characteristics of and MRSA isolated from foods of animal origin confiscated from passengers on flights from 45 non-EU countries from 2012 to 2015 by the Border Authorities at Bilbao International Airport (Spain) and Vienna International Airport (Austria), as well as foods from open markets close to EU land borders. Of 868 food samples tested (diverse meat samples including antelope, duck, guinea pig, pork, rodents, turkey, dairy products, and eggs), 136 (15.

Antimicrobial Activity of Copaiba (Copaifera officinalis) and Pracaxi (Pentaclethra macroloba) Oils against Staphylococcus Aureus: Importance in Compounding for Wound Care.

The Amazon rainforest is the largest reserve of natural products in the world. Its rich biodiversity of medicinal plants has been utilized by local populations for hundreds of years for the prevention and treatment of various diseases and ailments. Oil extracts from plant species such as Copaifera officinalis and Pentaclethra macroloba are used in compounded formulations for their antiinflammatory, antimicrobial, emollient, moisturizing, and wound-healing activities.

Occurrence and antimicrobial drug susceptibility patterns of commensal and diarrheagenic Escherichia coli in fecal microbiota from children with and without acute diarrhea.

Acute diarrhea is a public health problem and an important cause of morbidity and mortality, especially in developing countries. The etiology is varied, and the diarrheagenic Escherichia coli pathotypes are among the most important. Our objectives were to determine the occurrence of commensal and diarrheagenic E.

Quantitative relationship between maximum growth rates and the intracellular pattern of alpha-esterase and beta-esterase activity of leguminous infecting bacteria.

Sixteen strains belonging to three families of the Rhizobiales order (Bradyrhizobiaceae, Phyllobacteriaceae and Rhizobiaceae) were evaluated according their specific growth rates (micro) and the activity of intracellular alpha-esterase and beta-esterase isoenzymes. The average esterase activity of 48 isoenzymes assayed belonging to five strains with low (micro(max) = 0.08-0.

Self-assembly of diphenyltin(IV) and tris-dithiocarbamate ligands to racemic trinuclear cavitands and capsules.

Racemic trinuclear diphenyltin(IV) cavitands and capsules have been assembled from diphenyltin(IV) and tris-dithiocarbamate ligands.

Cytotoxic Activities of O-Cholesteryl-O-Phenyl-N-Phenylphosphoramidate and Its Organometallic Tin(lV) Derivatives.

O-Cholesteryl-O-phenyl-N-phenylphosphoramidate (1) and four organotin (lV) derivatives of the ambidentate O-cholesteryl-O -phenyl phosphorothioate ligand formulated as Me(3) SnOSPR'R"(2), Ph(3)SnOSPR'R"(3), O(CH(2)CH(2)S)(2)Sn(n-Bu)OSPR'R"(4), S(CH(2)CH(2)S)(2)Sn(n-Bu)OSPR'R"(5), (R' = O-phenyl; R"= O-cholesteryl) were subjected to cytotoxicity screening against KB (nasopharingel carcinoma), OVCAR-5 (ovarium carcinoma) and SQC-1 UlSO (squamous cell cervix carcinoma) cell cultures. The results of the bioassay showed that these compounds possess potent antitumor activities against the studied human carcinoma cell lines.
