Article Synopsis
- The study investigates antibiotic prescribing practices in adult ICUs across Brazil to address the issues related to multidrug-resistant infections in low- and middle-income countries.* -
- A survey conducted in 58 ICUs found that 63.9% of the 620 patients were on antibiotics, with 72.3% receiving empirical treatment, indicating a lack of reliance on microbiological testing.* -
- The findings show a high incidence of pneumonia and bloodstream infections, with significant variations in antibiotic use between teaching and non-teaching hospitals, raising concerns about healthcare-associated infections.*
Article Synopsis
- The study examined the ability of Acinetobacter baumannii and Klebsiella pneumoniae strains, from a Brazilian hospital, to form biofilms, focusing on their genetic variations and resistance profiles.
- Researchers conducted adhesion assays and quantitative evaluations of biofilm production in 10 strains of each species and found that A. baumannii showed better attachment compared to K. pneumoniae, with no isolates classified as strong biofilm producers.
- Results indicated that biofilm formation varies among strains and is not linked to clonal types or multidrug resistance, though more virulent K. pneumoniae strains tended to produce more biofilms.
Article Synopsis
- This study examined the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in a sample of 120 healthy elderly individuals, revealing a colonization rate of 19% for MRSA.
- Researchers used PCR to analyze various genes associated with MRSA, finding specific genetic markers in the community-acquired (CA)-MRSA isolates.
- The findings suggest that this population might be a potential reservoir for CA-MRSA, indicating the need for monitoring and preventive measures in community settings.

This study evaluated the predictors of mortality and the impact of inappropriate therapy on the outcomes of patients with bacteraemia and ventilator-associated pneumonia (VAP). Additionally, we evaluated the correlation of the type III secretion system (TTSS) effector genotype with resistance to carbapenems and fluoroquinolones, mutations in the quinolone resistance-determining regions (QRDRs), metallo-β-lactamase and virulence factors. A retrospective cohort was conducted at a tertiary hospital in patients with multidrug-resistant (MDR) P.
