Antimicrobial resistance was investigated in 91 Salmonella enteritidis isolates from broiler carcasses, food, human and poultry-related samples originated from South of Brazil. A great proportion of resistant strains was found, 90.1% showing resistance to at least one antimicrobial drug. There was a high resistance to sulfonamides (75.8%) and nitrofurantoin (52.8%). Lower levels of resistance were found for tetracycline (15.4%), streptomycin (7.7%), nalidixic acid (7.7%), gentamicin (5.5%), norfloxacin (3.3%), trimethoprim (3.3%), cefalotin (2.2%), ampicillin (1.1%), and chloramphenicol (1.1%). Resistance to ciprofloxacin was not detected. A total of 51.6% of S. enteritidis strains were multiresistant (resistance to two or more antimicrobial agents) and 18 resistance patterns were found. The highest resistance was found in strains isolated from poultry-related samples, where all strains were resistant to at least one antimicrobial agent. No predominant resistance pattern was related to phage type in our isolates. The high number of antimicrobial resistant S. enteritidis found in Southern Brazil indicates the need for the prudent drugs uses to diminish the development and spread of antimicrobial resistance.

Objectives: Staphylococcus aureus is part of the human microbiota, but at the same time, it is capable of causing a wide range of diseases. Due to the ever-increasing resistance to antimicrobial agents and the existence of methicillin-resistant S. aureus (MRSA) strains, there is a real possibility of carrying even this resistant bacterium, which can subsequently cause a severe infection.

Objective: This study aimed to evaluate the occurrence of methicillin-resistant Staphylococcus aureus (MRSA) at the University Hospital Olomouc (UHO) over a 10-year period (2013-2022).
Material And Methods: Data was obtained from the ENVIS LIMS laboratory information system (DS Soft, Czech Republic, Olomouc) of the Department of Microbiology, UHO, for the period 1/1/2013-31/12/2022. Standard microbiological procedures using the MALDI-TOF MS system (Biotyper Microflex, Bruker Daltonics) were applied for the identification.

Multifunctional membranes applied to biomedical materials become attractive to support the biological agents and increase their properties. In this study, biopolymeric fibers based on polycaprolactone (PCL) and pectin (PEC) were reinforced with faujasite zeolite (FAU) for cloxacillin antibiotic (CLX) loading. FAU with a high specific surface area (347 ± 8 m g), high crystallinity and particles with a diameter of up to 100 nm were produced under optimized synthesis conditions (100 °C/4 h).

Ciprofloxacin (CIP) is an extensively used broad-spectrum, fluoroquinolone antibiotic used for treating diverse bacterial infections. Effluent treatment plants (ETPs) worldwide lack technologies to detect or remediate antibiotics. CIP reaches the aquatic phase primarily due to inappropriate disposal practices, lack of point-of-use sensing, and preloaded activated charcoal filter at ETPs.
