HPV-related external genital lesions among men residing in Brazil

Braz. j. infect. dis; 21 (4), 2017
Abstract The aims of this study were to determine the incidence of external genital lesions (EGLs), specifically histologically confirmed condyloma (genital warts) and Penile Intraepithelial Neoplasia (PeIN), and genital HPV infection progression to EGLs among healthy men aged 18-73 residing in Brazil. S...

Role of MyD88-adaptor-like gene polymorphism rs8177374 in modulation of malaria severity in the Pakistani population

Braz. j. infect. dis; 21 (4), 2017
Abstract Introduction: The present study was designed to investigate the association between rs8177374 polymorphism and malaria symptoms due to exposure of Plasmodium vivax and Plasmodium falciparum. Materials and methods: A total of 454 samples were included in the study (228 malaria patients and 226 ...

Distribution of HBV subgenotypes in Ribeirão Preto, Southeastern Brazil: a region with history of intense Italian immigration

Braz. j. infect. dis; 21 (4), 2017
Abstract Hepatitis B virus (HBV) is distributed worldwide, with geographical variations regarding prevalence of the different genotypes. The aim of this study was to determine the HBV genotypes and subgenotypes circulating in Southeast Brazil and compare the genetic sequences found with HBV sequences pre...

Combined parasitological and molecular-based diagnostic tools improve the detection of Trypanosoma cruzi in single peripheral blood samples from patients with Chagas disease

Abstract INTRODUCTION In order to detect Trypanosoma cruzi and determine the genetic profiles of the parasite during the chronic phase of Chagas disease (ChD), parasitological and molecular diagnostic methods were used to assess the blood of 91 patients without specific prior treatment. METHODS Blood s...

Association of caspase-1 polymorphisms with Chagas cardiomyopathy among individuals in Santa Cruz, Bolivia

Abstract INTRODUCTION: Trypanosoma cruzi (Tc) infection is usually acquired in childhood in endemic areas, leading to Chagas disease, which progresses to Chagas cardiomyopathy in 20-30% of infected individuals over decades. The pathogenesis of Chagas cardiomyopathy involves the host inflammatory respons...

Community-acquired methicillin-resistant Staphylococcus aureus carrying SCCmec type IV and V isolated from healthy children attending public daycares in northeastern Brazil

Abstract Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) have increasingly been reported in healthy communities. This study aimed to assess the rate of S. aureus in general and MRSA in particular from nasal secretion of children in daycare centers in Vitória da Conquista, Braz...

Molecular epidemiology of Streptococcus agalactiae isolated from mastitis in Brazilian dairy herds

Braz. j. microbiol; 48 (3), 2017
Abstract Streptococcus agalactiae is one of the most common pathogens leading to mastitis in dairy herds worldwide; consequently, the pathogen causes major economic losses for affected farmers. In this study, multilocus sequence typing (MLST), genotypic capsular typing by multiplex polymerase chain react...

Correlation between virulence markers of Helicobacter pylori in the oral cavity and gastric biopsies

Arq. gastroenterol; 54 (3), 2017
ABSTRACT BACKGROUND: The clinical outcome of Helicobacter pylori infection has been associated with virulence factors. The presence of these factors is useful as molecular markers in the identification of the high risk for developing severe gastric pathologies. OBJECTIVE: To correlate the presence of v...

Asociación de variantes polimorfas de los genes PTPN22 , TNF y VDR en niños con nefritis lúpica: un estudio de tríos en familias colombianas

Biomédica (Bogotá); 37 (2), 2017
RESUMEN Introducción. El lupus eritematoso sistémico es una enfermedad autoinmunitaria cuya gravedad varía según la raza, el sexo y la edad de aparición. Esta disparidad también se observa en los marcadores genéticos asociados con la enfermedad presentes en los genes PTPN22, VDR y TNF. La estrati...
