13. Unusual association of NDM-1 with KPC-2 and armA among Brazilian Enterobacteriaceae isolates
We report the microbiological characterization of four New Delhi metallo-β-lactamase-1 (blaNDM-1)-producing Enterobacteriaceae isolated in Rio de Janeiro, Brazil. blaNDM-1 was located on a conjugative plasmid and was associated with Klebsiella pneumoniae carbapenemase-2 (blaKPC-2) or aminoglycoside-resistance methylase (armA), a 16S rRNA methylase not previ

14. Multidrug-resistant tuberculosis
Despite the efforts made worldwide to reduce the number of cases of drug-susceptible tuberculosis, multidrug-resistant tuberculosis (MDR-TB) constitutes an important public health issue. Around 440,000 new cases of MDR-TB are estimated annually, although in 2008 only 7% of these (29,423 cases) were notified. The laboratory tests for diagnosing resistance may

15. The modified Hodge test is a useful tool for ruling out Klebsiella pneumoniae carbapenemase
OBJECTIVE: Enterobacteriaceae bacteria harboring Klebsiella pneumoniae carbapenemase are a serious worldwide threat. The molecular identification of these pathogens is not routine in Brazilian hospitals, and a rapid phenotypic screening test is desirable. This study aims to evaluate the modified Hodge test as a phenotypic screening test for Klebsiella pneumo

16. A survey on pulmonary pathogens and their antibiotic susceptibility among cystic fibrosis patients
OBJECTIVE:This study was performed to investigate frequency and antimicrobial susceptibility of pulmonary pathogens in cystic fibrosis (CF) patients. METHODS: 129 pediatric patients with CF were enrolled in this cross-sectional study. Microbiological cultures were performed based on sputum or pharyngeal swabs. Antibiotic susceptibilities of the isolated bact

17. Increasing antibiotic resistance among uropathogens isolated during years 2006-2009: impact on the empirical management
Urinary tract infections (UTI) are one of the most common infections with an increasing resistance to antimicrobial agents. PURPOSE: Empirical initial antibiotic treatment of UTI must rely on susceptible data from local studies. MATERIALS AND METHODS: Retrospective analysis of isolated bacteria from children with UTIs was performed at the university hospital

18. Length of exposure to the hospital environment is more important than antibiotic exposure in healthcare associated infections by methicillin-resistant Staphylococcus aureus: a comparative study
OBJECTIVES: Both total antimicrobial use and specific antimicrobials have been implicated as risk factors for healthcare-associated methicillin-resistant Staphylococcus aureus (HCA-MRSA) infection. The aims of this study were: (I) to explore predictors of a new HCA-MRSA infection in comparison with a new healthcare-associated methicillin-sensitive Staphyloco

19. Potentiation of aminoglycoside antibiotic activity using the body fat from the snake Boa constrictor
Boa constrictor is widely used in traditional communities in many different folk remedies and products derived from it are sold in public markets throughout northeastern Brazil and as its body fat has many different therapeutic indications as a folk remedy. The present work evaluates the antibacterial activity of the body fat from the snake Boa constrictor w

20. The prevalence of aminoglycoside-modifying enzyme genes (aac (6')-I, aac (6')-II, ant (2")-I, aph (3')-VI) in Pseudomonas aeruginosa
INTRODUCTION: Pseudomonas aeruginosa (P. aeruginosa) is one of the primary opportunistic pathogens responsible for nosocomial infections. Aminoglycosides are an import ant component of antipseudomonal chemotherapy. The inactivation of drugs by modifying enzymes is the most common mechanism of aminoglycoside resistance. OBJECTIVES: The inactivation of aminogl

21. Identification, antimicrobial resistance and genotypic characterization of enterococcus spp. isolated in Porto Alegre, Brazil
In the past two decades the members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. In the present study, we evaluated the antimicrobial resistance and genotypic characteristics of 203 Enterococcus spp. recovered from different clinical sources from two hospitals in Porto Alegre, Rio Grande do Sul, Brazil. The species were

22. Epidemiologia e fatores de risco associados à colonização por VRE e MRSA em uma unidade de terapia intensiva de adultos
This investigation included a total of 78 VRE-colonized patients and 17 MRSA-colonized patients through study of the incidence in the period April 2009 to January 2010. We evaluated the rates of infection/colonization with these phenotypes, risk factors for colonization, antimicrobial susceptibility profile and characterization of vanA gene in enterococci st

23. Brucella melitensis: a rarely suspected cause of infections of genitalia and the lower urinary tract
We examined the clinical presentation and outcome of Brucellar infections of genitalia and the lower urinary tract through a review of the medical records of 10 cases of male patients with brucellar infections of the genitalia and lower urinary tract. The mean age of the patients with brucellosis was 49.2, (median 52, range 15-77 years). Eleven out of 17 pat

24. Study of modulators genes associated to mutations in mitochondrial genes in individuals with non-syndromic deafness / Estudos de genes moduladores associados a mutações em genes mitocondriais em individuos com surdez não-sindromica
Hearing loss is the most prevalent sensorial deficit in the general population. Congenital deafness occurs in about 1 in 1000 live births, of which approximately 50% has hereditary cause in development countries. Non-syndromic deafness can be caused by mutations in both nuclear and mitochondrial genes. Mutations in mtDNA have been associated with aminoglycos
