1. Polymyxin Acute Kidney Injury: a case of severe tubulopathy
Resumo Polimixinas são um grupo de antibióticos desenvolvidos na década de 1950. Seus efeitos neurotóxicos são comumente descritos na literatura, porém há menos relatos sobre seus efeitos nefrotóxicos, especialmente tubulopatias. O objetivo deste relato é descrever o uso de polimixina B em uma paciente para tratamento de infecção de ferida operat�

2. Clinical Study of Sodium Hypochlorite, Polymyxin B And Limewater Effect on MMP-3,-8,-9 In Apical Periodontitis
Resumo O objetivo deste estudo foi avaliar o hipoclorito de sódio (NaOCl), água de cal (LW) e polimixina B (PMB) como soluções irrigadoras sobre MMP-3, MMP-8 e MMP-9. Trinta e três pacientes com periodontite apical de dentes unirradiculares foram tratados de acordo com três grupos experimentais (n= 11): grupo 1: 2,5% NaOCl foi usado como solução irri

3. Pseudomonas aeruginosa in the ICU: prevalence, resistance profile, and antimicrobial consumption
Abstract INTRODUCTION: Pseudomonas aeruginosa is one of the main pathogens causing infection in intensive care units (ICUs) and usually presents antimicrobial resistance. METHODS: Data were obtained from ICUs between 2010 and 2013. RESULTS: P. aeruginosa had a prevalence of 14.5% of which 48.7% were multidrug resistant. We observed increasing resistance t

4. Post-neurosurgical meningitis caused by KPC-producing Klebsiella pneumoniae: report of two cases
ABSTRACT Nosocomial bacterial infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) is associated with high mortality in neurosurgical patients. There are few reports in the literature on meningitis caused by CRKP. We report two cases of CRKP meningitis after neurosurgery. The K. pneumoniae identification and antimicrobial susceptibility tes

5. Chromobacteriosis (Chromobacterium violaceum) in a calf from Brazil - case report
RESUMO Chromobacterium violaceum é um patógeno oportunista raro, que causa infecção fatal em animais domésticos e em humanos. Este relato descreve um caso fatal suspeito de septicemia em um bezerro de quatro dias, fêmea, infectado por C. violaceum. O bezerro apresentava onfaloflebite supurativa, poliartrite supurativa fibrinosa, uveíte anterior com de

6. Antimicrobial susceptibility and minimal inhibitory concentration of bacteria isolated from the eyes of dogs with keratoconjunctivitis sicca
RESUMO: O objetivo deste estudo foi avaliar o perfil de susceptibilidade antimicrobiana de bactérias isoladas de olhos de cães com ceratoconjuntivite seca (CCS). Foram avaliados 65 cães com diagnóstico de CCS e 30 cães saudáveis (Grupo Controle). Depois do diagnosticado de CCS, suabes conjuntivais foram coletados. Exames microbiológicos foram realizad

7. Multidrug-resistant Klebsiella pneumoniae: genetic diversity, mechanisms of resistance to polymyxins and clinical outcomes in a tertiary teaching hospital in Brazil
ABSTRACT Increased resistance to polymyxin in Klebsiella pneumoniae (ColRKP) has been observed. Molecular epidemiology, as well as the clinical impact of these difficult to treat pathogens need to be better characterized. We present the clinical outcomes of 28 patients infected by ColRKP in a tertiary hospital. Isolates with MIC >2 by Vitek 2 were confirmed

8. Early use of polymyxin B reduces the mortality of carbapenem-resistant Klebsiella pneumoniae bloodstream infection
ABSTRACT Polymyxin B is one of the last resort option for carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infection in China. Therefore, the timing of administration of polymyxin is frequently delayed. We collected 40 cases of CRKP bloodstream infections (BSIs) treated with combinations based on polymyxin B over 30 months. The primary outcome,

9. Non-clonal occurrence of pmrB mutations associated with polymyxin resistance in carbapenem-resistant Klebsiella pneumoniae in Brazil
BACKGROUND Polymyxins are currently used as a “last-line” treatment for multidrug-resistant Gram-negative infections. OBJECTIVES To identify the major mechanisms of resistance to polymyxin and compare the genetic similarity between multi-drug resistant Klebsiella pneumoniae strains recovered from inpatients of public hospitals in the Mid-West of Braz

11. Effect of polymyxin B-containing regimens on renal function for the treatment of carbapenem-resistant Enterobacteriacea mediastinitis
ABSTRACT A retrospective cohort study, were evaluated: polymyxin B plus aminoglycosides or polymyxin B plus other antibiotics. Any degree of acute kidney injury occurred in 26 (86.6%) patients. The median time to acute kidney injury was 6.0 (95% CI 3–14) days in the polymyxin-aminoglycoside containing regimen group, against 27.0 (95% CI 6–42) days in the
