1. A globally applicable PCR-based detection and discrimination of BK and JC polyomaviruses
ABSTRACT BKV and JCV belong to the Polyomaviridae family and are opportunistic agents associated with complications in immunocompromised individuals. Although a single screening assay for both viruses would be convenient, the diversity of BKV and JCV serotypes and genotypes is a methodological challenge. In this paper, we developed a PCR method able to detec

2. Investigation of Enteric Viruses in the Feces of Neotropical Migratory Birds Captured on the Coast of the State of Pará, Brazil
ABSTRACT Migratory birds can become long-distance vectors for a wide range of microorganisms and can cause human disease, being the Brazilian coast a gateway for northern migratory birds. These animals are considered natural reservoirs of different viruses that cause important diseases, being relevant research of viral pathogens in migratory birds to epidemi

3. Aspectos epidemiológicos, clínicos e patológicos da infecção pelo parvovirus canino 2c em cães do Sul do Brasil
RESUMO: O parvovírus canino tipo 2c (CPV-2c) surgiu na Europa no início do ano 2000 e rapidamente se espalhou pelas populações de cães ao redor do mundo. Dados clínicos e moleculares demonstraram a sua circulação em cães brasileiros, porém descrições detalhadas desses casos ainda são escassas. Este artigo descreve os aspectos epidemiológicos, c

4. High-level phylogeographic structuring of Neoleucinodes elegantalis Guenée (Lepidoptera, Crambridae) in Brazil: an important tomato pest
ABSTRACT Neoleucinodes elegantalis is an important tomato pest in Brazil, occurring throughout the country and resulting in economic losses in agriculture. In several species, biogeographic studies in Brazil indicate the structuring of populations, following the refuge model, with a split between the populations of the northeast and the southeast regions of

5. Nasal carriage of resistant Staphylococcus aureus in a medical student community
ABSTRACT Staphylococcus aureus can cause a variety of infections due to its high transmissibility, high pathogenic potential and resistance to multiple drugs, factors that contribute to the relevance of infections in healthcare services. The aim of this study was to document phenotypic and genotypic resistance factors of Staphylococcus aureus strains, isolat

6. Phylogenetic characterization of the first Ungulate tetraparvovirus 2 detected in pigs in Brazil
Abstract Ungulate tetraparvovirus 2 (UTV2) , formerly known as porcine hokovirus due to its discovery in Hong Kong, is closely related to a Primate tetraparvovirus (human PARV-4) and Ungulate tetraparvovirus 1 (bovine hokovirus). Until now, UTV2 was detected in European, Asian and North American countries, but its occurrence in Latin America is still unknown

7. Production of Brazilian human norovirus VLPs and comparison of purification methods
Abstract Noroviruses (NVs) are responsible for most cases of human nonbacterial gastroenteritis worldwide. Some parameters for the purification of NV virus-like particles (VLPs) such as ease of production and yield were studied for future development of vaccines and diagnostic tools. In this study, VLPs were produced by the expression of the VP1 and VP2 gene

8. Molecular characterisation of the NSP4 gene of group A human rotavirus G2P[4] strains circulating in São Paulo, Brazil, from 1994 and 2006 to 2010
Group A human rotaviruses (HuRVA) are causative agents of acute gastroenteritis. Six viral structural proteins (VPs) and six nonstructural proteins (NSPs) are produced in RV-infected cells. NSP4 is a diarrhoea-inducing viral enterotoxin and NSP4 gene analysis revealed at least 15 (E1-E15) genotypes. This study analysed the NSP4 genetic diversity of HuRVA G2P

9. Estudo filogenético do parvovírus canino tipo 2c no Centro-Oeste do Brasil
Desde o final dos anos de 1970, o parvovírus canino tipo 2 (CPV-2) tem emergido como agente de severa e fatal enterite hemorrágica, principalmente em cães com idade inferior a seis meses. Três variantes antigênicas de CPV-2 foram descritas mundialmente (CPV-2a/b/c). O objetivo do estudo foi determinar a presença do CPV-2 e suas variantes circulantes em

10. Partial VP1 sequencing of Brazilian infectious bursal disease virus strains
Infectious bursal disease virus (IBDV) is classified according to the antigenicity and virulence into classical virulent (cv), very virulent (vv), and antigenic variant strains. The molecular basis for the IBDV antigenic variation is well established and is associated to the capsid protein, VP2 (gene VP2 of segment A), whereas both VP2 and the RNA-dependent

11. Detecção de rotavírus em amostras fecais de bovinos e água em propriedades rurais do vale do Paranhana, RS
The aim of present study was to assess a possible relationship between the contamination of water sources with animal husbandry in the region. In the localities belonging to Paranhana valley, the municipalities of Taquara, Rolante e Riozinho, were collected 104 water samples from different sources including tap water, ponds, dug wells, boreholes, streams, ri

12. Efeitos de raios-X de baixa energia em células mamárias / Effects of low energy x-rays in mammary cells
Radiation doses of low-energy can induce double-stranded breaks in DNA as well resulting in altered profiles of gene expression related to these injuries. The damage is not repaired or poorly repaired leading to increased susceptibility to oncogenic transformation since most important biological effects caused by ionizing radiation are mutation and carcinoge
