1. Combination of commercially available molecular assays and culture based methods in diagnosis of tuberculosis and drug resistant tuberculosis
ABSTRACT Early diagnosis of tuberculosis is of major clinical importance. Among 4733 clinical specimens collected from 3363 patients and subjected to Ziehl-Neelsen microscopy, 4109 were inoculated onto Löwenstein-Jensen slants and 3139 in Bactec/9000MB. Polymerase Chain Reaction (PCR) was performed in 3139 specimens, whereas, a genotypic assay was directly

2. Detection and analysis of different interactions between resistance mechanisms and carbapenems in clinical isolates of Klebsiella pneumoniae
Abstract Carbapenems are considered last-line agents for the treatment of serious infections caused by Klebsiella pneumoniae, and this microorganism may exhibit resistance to β-lactam antibiotics due to different mechanisms of resistance. We evaluated 27 isolates of K. pneumoniae resistant to carbapenems recovered from inpatients at the University Hospital

3. β-lactamase-producing Gram-negative bacteria in an intensive care unit in southern Brazil
ABSTRACT The present study evaluated the antimicrobial susceptibility profile, β-lactamase production, and genetic diversity of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter spp. using phenotypic identification, antimicrobial susceptibility testing, and β-lactamase phenotypic detection. Isolates were obtained from patients in an intensive c

4. Trends and predictors of HIV-1 acquired drug resistance in Minas Gerais, Brazil: 2002–2012
Abstract Several studies show that the prevalence of multidrug-resistant HIV-1 virus is declining over time. A retrospective cohort study was carried out to evaluate the trends of drug resistance in antiretroviral treatment-exposed individuals in a state of a middle-income country, Minas Gerais, southeast region of Brazil. We analyzed 2115 HIV-1 sequences fr

5. Peripheral regulation of stress and fear responses in pigs from tail-biting pens
ABSTRACT This study focused on stress physiology by characterizing cortisol responses to stressors in tail biters (n = 10), victims (n = 10), and control pigs (n = 10) of two different breeds (Landrace × Yorkshire, LY; Landrace/Yorkshire × Landrace/Duroc; LYLD) and sexes (females and castrated males). We exposed pigs to 10 min of isolation with a human at

6. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

7. Genotyping of multidrug-resistant strains of Pseudomonas aeruginosa isolated from burn and wound infections by ERIC-PCR
ABSTRACT PURPOSE: To determine the genetic diversity of MDR P. aeruginosa strains isolated from burn and wound infections in Ahvaz, Iran, by ERIC-PCR. METHODS: From total 99 strains of P. aeruginosa defined as MDR by using drug susceptibility testing, 66 were subjected to ERIC-PCR analysis, comprises 53 strains isolated from burn infection, and 13 random

8. Phenotypic and genotypic characterization of Streptococcus agalactiae in pregnant women: first study in a province of Argentina
Group B Streptococcus (GBS) is the leading cause of neonatal infections. Our purpose was to characterize GBS colonization in pregnant women, current serotypes, resistance phenotypes and genes associated with virulence. In Misiones, Argentina, there are no previous data on this topic. Vaginal-rectal swabs from 3125 pregnant women were studied between 2004 and

9. Comparação genotípica e fenotípica de diferentes isolados clínicos e ambientais de Rhodotorula spp. / Genotypic and phenotypic comparisons among clinical and environmental isolates of Rhodotorula spp.
Introduction: Rhodotorula spp. are yeasts widely distributed in the environment and can colonize the human body at different anatomical locations. This emerging pathogen is capable of causing superficial and invasive infections in humans whereas bloodstream infection is the most commonly described in the literature. Mainly three species have been related to

10. CaracterizaÃÃo fenotÃpica e genotÃpica de bactÃrias do gÃnero Vibrio isoladas em alguns estuÃrios do Estado do Cearà / Phenotypic and genotypic characterization of bacteria Vibrio genus isolated in some estuaries of the State of CearÃ
The frequent association of environmental aquatic contamination with vibriosis in humans suggests the need for systematic monitoring and study of environmental vibrio strains and their pathogenic potential and clinical significance. The objective of this study was to evaluate the diversity of vibrio species in four estuaries (Pacoti, ChorÃ, Pirangi and Jagu

11. Cromoblastomicose no Maranhão: uma abordagem microbiológica, ambiental e molecular
The chromoblastomycosis (CBM) is a chronic fungal infection of skin and subcutaneous tissue caused by several melanized fungi of Chaetotrhyales order. Fonsecaea pedrosoi is the major causative agent of the disease. This study aimed to evaluate the clinical and epidemiological aspects of patients with CBM and phenotypic and genotypic characterization of the a

12. Phenotypic and genotypic characterization of Salmonella enteritidis isolates
In order to study the epidemiology of Salmonella Enteritidis outbreaks and determine the source of contamination so that a recurrence can be avoided, detailed characterization is necessary. Thus, the purpose of this study was to verify whether rep-PCR was able to discriminate among Salmonella Enteritidis isolates. Phage typing, detection of virulence genes a
