Article Synopsis
  • - This study estimated the impact of bloodstream infections (BSIs) caused by gram-negative bacteria (GNB) in a Brazilian hospital over four years (2015-2019) using disability-adjusted life-years (DALYs) as a measure of disease burden.
  • - Researchers analyzed medical records of 498 patients, revealing that carbapenem-resistant gram-negative bacteria (CR-GNB) contributed significantly to the high burden, particularly peaking in 2017 with alarming rates of DALYs and a high mortality rate.
  • - The findings highlight a critical public health issue in Brazil, stressing the need for urgent interventions to combat infections from antibiotic-resistant bacteria as they could lead to substantial future mortality during hospitalizations.

Objective: to determine the rate of hospitalizations due to acute non-drug poisoning (NDP) events and to analyze mortality arising from these health conditions in Brazil from 2009 to 2018.

Methods: this was a time-series study using Prais-Winsten regression to analyze records of hospitalizations for "treatment of intoxication or poisoning due to exposure to non-drug substances" held on the Hospital Information System.

Results: there were 125,570 hospitalizations due to NDP.

Objectives: To determine the incidence, aetiology and pneumococcal serotype distribution of community-acquired pneumonia (CAP) in Brazilian adults during a 2-year period.

Design: Prospective population-based surveillance study.

Setting: Patients from two emergency hospitals in Brazil were consecutively included in this study.

Objectives: To investigate the occurrence of Trichosporon asahii fungemia among critically ill COVID-19 patients.

Methods: From 1 July to 30 September 2020, cases of T asahii fungemia (TAF) in a Brazilian COVID-19 referral centre were investigated. The epidemiology and clinical courses were detailed, along with a mycological investigation that included molecular species identification, haplotype diversity analysis and antifungal susceptibility testing.

Background: Bloodstream infections (BSI) are associated with high morbidity and mortality. This scenario worsens with the emergence of drug-resistant pathogens, resulting in infections which are difficult to treat or even untreatable with conventional antimicrobials. The aim of this study is to describe the epidemiological aspects of BSI caused by multiresistant gram-negative bacilli (MDR-GNB).

Carbapenemases have great importance in the global epidemiological scenario since infections with carbapenemase-producing bacteria are associated with high mortality, especially in hospitalized patients in intensive care units. This study describes two microorganisms producers of the New Delhi Metallo-b-lactamase, Klebsiella pneumoniae and Citrobacter freundii, from two patients admitted to a public hospital in Salvador, Bahia. These are the first clinical cases of New Delhi Metallo-b-lactamase described in microorganisms in the north and northeast Brazil.

Bloodstream infections (BSIs) are among the most concerning bacterial infections. They are one of the leading causes of morbidity and mortality, and occur in 30-70% of critical care patients. The prompt identification of the causative microorganism can help choosing the appropriate antimicrobial therapy that will lead to better clinical outcomes.

The clinical management of meningitis caused by Escherichia coli is greatly complicated when the organism becomes resistant to broad-spectrum antibiotics. We sought to characterize the antimicrobial susceptibilities, sequence types (ST), and presence of known drug resistance genes of E. coli isolates that caused meningitis between 1996 and 2011 in Salvador, Brazil.

Milk may represent an important source of infectious agents to hospitalized pediatric patients. To describe the bacterial microflora isolated from the hands, stools, pharynx of all workers at milk kitchens in pediatric hospitals in the city of Salvador, Brazil, as well as in the formulas prepared by them, we carried out this cross-sectional study with all 91 workers from the 20 milk kitchens of all the public and private hospitals in Salvador, Brazil. Hand and pharynx swabs and stool samples were collected from all workers, as well as samples of the milk and formulas delivered by the kitchens.

To report the frequency of methicillin-resistant Staphylococcus aureus (MRSA) infection and to compare the antimicrobial resistance patterns between community-acquired (CA) and nosocomial (NI) strains stratified for resistance to methicillin, this retrospective study on patients under 20 years of age was conducted from April 1995 to December 2005 in a pediatric teaching hospital in Salvador, Brazil. Of 308 S. aureus strains isolated, 185 (60.

Objectives: To describe the antimicrobial resistance and serotype distribution of pneumococcal strains.

Methods: In a 57-month period, a laboratory-based surveillance of invasive pneumococcal strains from patients aged < 20 years was conducted. Pneumococcus was identified by means of tests for solubility in bile and optochin.
