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...
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...
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...
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 ...
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...
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...
Al comenzar la década de los '80 se reconoce por primera vez el Síndrome de InmunoDeficiencia Adquirida en 1983 en París, Francia, identifican por primera vez el virus del SIDA y a principio de 1984 se confirma el descubrimiento, la gran mayoría de los casos de SIDA ocurren en homosexuales o bisexual...
