13. Feline herpesvirus 1 viral load related to environmental factors in sheltered cats
RESUMO: No ambiente do abrigo encontram-se fatores que geram estresse nos animais que ali residem. Esses fatores acabam por provocar a reativação do FHV-1. No entanto, comparações entre carga viral conjuntival e fatores ambientais não foram ainda avaliadas. Objetivo deste estudo foi correlacionar a carga viral de FHV-1 em felinos domésticos com e sem

14. Molecular detection of bovine immunodeficiency virus (BIV) in bovines from the state of Minas Gerais, Brazil
RESUMO O vírus da imunodeficiência bovina é o agente causador da imunodeficiência viral bovina que é conhecido por infectar bovinos em todo o mundo. Como em outras infecções por retrovírus, os hospedeiros desenvolvem uma infecção de longo prazo e a maioria dos animais infectados permanece assintomática. O objetivo deste estudo foi detectar DNA pro

15. Bovine alphaherpesvirus 1 and 5 in semen from bulls presenting genital lesions under field conditions in Brazil
RESUMO Os alfa-herpesvírus bovinos 1 e 5 (BoHV-1/5) são importantes patógenos de doença respiratória, reprodutiva e neurológica em bovinos. O objetivo deste estudo foi investigar a frequência de detecção de anticorpos neutralizantes contra BoHV-1/5 em amostra de soro e detectar DNA viral em sêmen de touros do rebanho bovino localizado nas fazendas

16. Methylation of p16 ink4a promoter is independent of human papillomavirus DNA physical state: a comparison between cervical pre-neoplastic and neoplastic samples
BACKGROUND Epigenetic modifications in host cells, like p16 ink4a methylation, have been considered as putative complementary mechanisms for cancer development. Because only a small proportion of infected women develop cervical cancer, other factors might be involved in carcinogenesis, either independently or in association with high-risk human papillomavir

17. Human polyomaviruses and cancer: an overview
The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice. Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumorigenesis in different experimental models. The transfo

18. Human papillomavirus and genome instability: from productive infection to cancer
Infection with high oncogenic risk human papillomavirus types is the etiological factor of cervical cancer and a major cause of other epithelial malignancies, including vulvar, vaginal, anal, penile and head and neck carcinomas. These agents affect epithelial homeostasis through the expression of specific proteins that deregulate important cellular signaling

19. Phylogenetic analysis and genotype distribution of Hepatitis B Virus (HBV) in Roraima, Brazil
ABSTRACT Hepatitis B virus (HBV) infection is a serious global health problem. HBV has a high viral genetic diversity, with 10 genotypes recognized. In Brazil, the Roraima State is the third in the Northern region regarding the number of hepatitis B cases. On the other hand, few data on HBV genotyping and phylogenetic analysis are available. The purpose of t

20. Preparation and characterization of non-viral gene delivery systems with pEGFP-C1 Plasmid DNA
ABSTRACT In recent years, non-viral delivery systems for plasmid DNA have become particularly important. They can overcome the disadvantages of viral systems such as insertional mutagenesis and unpredicted immunogenicity. Some additional advantages of non-viral gene delivery systems are; good stability, low cost, targetability, delivery of a high amount of g

21. Is the telomere length associated with neurocognitive disabilities in HIV-1-infected subjects?
ABSTRACT Objective: We evaluated the association between cognitive deficits and leukocyte telomere length (LTL) in HIV-1-infected individuals. Design: 73 HIV-1-infected patients undergoing neuropsychological evaluation and 91 healthy controls were included in this study. Fifteen HIV-1 positive patients did not have cognitive disorders whereas 26 had asympt

22. HCMV UL97 phosphotransferase gene mutations may be associated with antiviral resistance in immunocompromised patients in Belém, PA, Northern Brazil
Abstract INTRODUCTION: Human cytomegalovirus is one of the causes of opportunist infections in immunocompromised patients, and is triggered by factors such as state of viral latency, weakened immune responses, and development of antiviral resistance to ganciclovir, the only drug offered by the public health system in Brazil to treat the infection. The goal

23. Surto de bouba aviária na forma cutânea em perus comerciais previamente vacinados
RESUMO: Este estudo descreve um surto de bouba aviária em perus previamente vacinados contra poxvirus aviário no Brasil. Os perus apresentaram lesões macroscópicas, sugestivas de bouba aviaria cutânea, na pele da cabeça e região cervical sem alteração nas taxas de mortalidade do lote. No abatedouro, 30 carcaças foram retiradas da linha de abate par

24. In vitro basal T-cell proliferation among asymptomatic Human T cell Leukemia Virus type 1 patients co-infected with hepatitis C and/or Human Immunodeficiency Virus type 1
ABSTRACT Background: Infection with Human T cell Leukemia Virus type 1 can be associated with myelopathy/tropical spastic paraparesis (HAM/TSP) and other inflammatory diseases. Lymphocytes from about half of Human T cell Leukemia Virus type 1-infected subjects spontaneously proliferate in vitro, and how this phenomenon relates to symptomatic disease and vir
