Novel variants of human herpesvirus 2 from Brazilian HIV-1 coinfected subjects

Mem. Inst. Oswaldo Cruz; 113 (12), 2018
BACKGROUND Human herpesvirus 2 (HHV-2) have DNA genome with a limited genetic variability and have been classified into two clades. OBJECTIVES To identify and characterise six HHV-2 isolates derived from Brazilian women. METHODS HHV-2 isolates were performed polymerase chain reaction (PCR) and sequencing...

Detection and genotyping of human adenovirus and sapovirus in children with acute gastroenteritis in Belém, Pará, between 1990 and 1992: first detection of GI. 7 and GV. 2 sapoviruses in Brazil

Abstract INTRODUCTION: Acute gastroenteritis (AGE) is one of the most common causes of morbidity and mortality, especially among children from developing countries. Human adenovirus (HAdV) and sapovirus (SaV) are among the agents that cause AGE. The present study aimed to detect and genotype HAdV and S...

A highly sensitive method for the detection of Chrysanthemum virus B

Background: Chrysanthemum plants are subject to serious viral diseases. The viruses cause severe losses of the quantity and quality of chrysanthemum. The most problematic pathogen of chrysanthemum is typically considered Chrysanthemum virus B (CVB). Thus, a method for the simultaneous detection of CVB is...

Diversity of group A rotavirus genes detected in the Triângulo Mineiro region, Minas Gerais, Brazil

Braz. j. microbiol; 47 (3), 2016
ABSTRACT Group A rotaviruses are the main causative agent of infantile gastroenteritis. The segmented nature of the viral genome allows reassortment of genome segments, which can generate genetic variants. In this study, we characterized the diversity of the VP7, VP4 (VP8*), VP6, NSP4, and NSP5 genes of ...

Posible papel del factor de transcripción AP1 en la regulación tejido-específica del papilomavirus humano
Possible role of transcription factor AP1 in the tissue-specific regulation of human papillomavirus

Rev. invest. clín; 54 (3), 2002
Activator protein-1 (AP1) is a dimeric protein, consisting either of homodimers between c-Jun, JunB, and JunD of by heterodimers with members of the Fos-family by physically interacting via a "leucine zipper" region. AP1 is an important transcription factor initially identified as a DNA binding protein t...

Regulación genética de los papilomavirus humanos genitales
Genetic regulation of human genital papillomavirus

Salud pública Méx; 37 (3), 1995
Los papilomavirus humano (PVH) infectan epitelios estratificados queratinizados con una alta especificidad y están asociados con la aparición y persistencia de neoplasias benignas y malignas. Los elementos que dirigen la expresión genética de estos virus se localizan en una región no codificadora co...
