Invasive Haemophilus influenzae disease in the vaccine era in Rio de Janeiro, Brazil

Mem. Inst. Oswaldo Cruz; 112 (3), 2017
BACKGROUND Haemophilus influenzae (Hi) serotype b (Hib) conjugate vaccine was incorporated into the infant immunisation schedule in Brazil in 1999, where Hib was one of the major etiologic sources of community-acquired bacterial meningitis. OBJECTIVES The purpose of this study is to describe the molecu...

Atividade antibacteriana de tubos endotraqueais revestidos com dióxido de titânio padrão e dopados com nitrogênio: um estudo in vitro

RESUMO Objetivo: Avaliar a atividade antibacteriana contra Staphylococcus aureus e Pseudomonas aeruginosa de dois revestimentos endotraqueais com nanopartículas e fotocatálise sob luz visível. Métodos: Testaram-se dois tipos de nanopartículas de titânio: anatase padrão (TiO2) e TiO2 nano-dopada ...

Biofilm production and beta-lactamic resistance in Brazilian Staphylococcus aureus isolates from bovine mastitis

Braz. j. microbiol; 48 (1), 2017
Abstract Staphylococcus spp. play an important role in the etiology of bovine mastitis. Staphylococcus aureus is considered the most relevant species due to the production of virulence factors such as slime, which is required for biofilm formation. This study aimed to evaluate biofilm production and its ...

Use of green fluorescent protein labeled non-tuberculous mycobacteria to evaluate the activity quaternary ammonium compound disinfectants and antibiotics

Braz. j. microbiol; 48 (1), 2017
Abstract Although infections with NonTuberculous Mycobacteria have become less common in AIDS patients, they are important opportunistic infections after surgical procedures, likely because they are ubiquitous and not efficiently killed by many commonly used disinfectants. In Venezuela there have recentl...

Genome sequence of Prevotella intermedia SUNY aB G8-9K-3, a biofilm forming strain with drug-resistance

Braz. j. microbiol; 48 (1), 2017
Abstract Prevotella intermedia has long been known to be as the principal etiologic agent of periodontal diseases and associated with various systemic diseases. Previous studies showed that the intra-species difference exists in capacity of biofilm formation, antibiotic resistance, and serological reacti...

Severe sepsis from a Ciprofloxacin resistant salmonellosis in a kidney transplant recipient

J. bras. nefrol; 39 (1), 2017
Abstract Introduction: Salmonellosis is a relatively rare complication in kidney transplant recipients that cannot be clinically distinguished from other forms of enteritis. Among kidney transplant patients, it varies broadly in intensity, and is highly associated with extra-intestinal disease, bacterem...

S-(+)- and R-(-)-linalool: a comparison of the in vitro anti-Aeromonas hydrophila activity and anesthetic properties in fish

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Linalool is the main compound of many essential oils and occurs in two isomeric forms: S-(+)- and R-(-)-linalool. This study aimed to determine if linalool isomers have different antimicrobial and anesthetic properties in fish. For this purpose, these compounds were previously isolated from Lipp...

Phenotypic methods for screening carbapenem-resistant Enterobacteriaceae and assessment of their antimicrobial susceptibility profile

Abstract INTRODUCTION: In this study, we used phenotypic methods to screen carbapenem-resistant Enterobacteriaceae (CREs) and evaluated their antimicrobial sensitivity profile. METHODS: One hundred and seventy-eight CREs were isolated at a university hospital in south Brazil in a one-year period. Samp...

Carbapenem-resistant Acinetobacter baumannii contamination in an intensive care unit

Abstract INTRODUCTION: Acinetobacter baumannii is a major pathogen causing infections in intensive care units (ICUs). In this study, we aimed to evaluate the presence of A. baumannii in an ICU environment and gloves from ICU workers and to characterize the antimicrobial resistance of the isolates in com...

Prevalence and antimicrobial susceptibility of non-fermenting Gram-negative bacilli isolated from clinical samples at a tertiary care hospital

Abstract INTRODUCTION: We compared the prevalence and antimicrobial susceptibility of non-fermenting gram-negative bacilli (NFGNB) isolated from clinical samples at a Brazilian tertiary care hospital in 2008 and 2013. METHODS: Collected data included patient's name, age, sex, inpatient unit, laborato...
