25. The level of ascorbate peroxidase is enhanced in benznidazole-resistant populations of Trypanosoma cruzi and its expression is modulated by stress generated by hydrogen peroxide
Ascorbate peroxidases (APX) are class I heme-containing enzymes that convert hydrogen peroxide into water molecules. The gene encoding APX has been characterized in 11 strains of Trypanosoma cruzi that are sensitive or resistant to benznidazole (BZ). Bioinformatic analysis revealed the presence of two complete copies of the T. cruzi APX (TcAPX) gene in the g

26. First detection of Rio Negro virus (Venezuelan equine encephalitis complex subtype VI) in Córdoba, Argentina
Rio Negro virus (RNV) (Venezuelan equine encephalitis subtype VI) circulates only in Argentina; in northern provinces, isolates have been obtained from mosquitoes and rodents since 1980 and have been associated with acute febrile illness in humans. However, no studies of RNV have been performed in the central area of the country. We carried out molecular and

27. 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

28. Indução de resistência ao Papaya meleira virus em mamoeiros
O mamoeiro (Carica papaya L.) é uma das fruteiras mais cultivadas e o mamão uma das frutas mais consumidas nas regiões tropicais e subtropicais do mundo. O Brasil é o maior produtor mundial de mamão e os estados do Espírito Santo e da Bahia são responsáveis por mais de 70% da área brasileira produtora deste fruto. As doenças, no entanto, constituem

29. Magnetic bead technology for viral RNA extraction from serum in blood bank screening
Nucleic acid amplification testing (NAT) was recently recommended by Brazilian legislation and has been implemented at some blood banks in the city of São Paulo, Brazil, in an attempt to reduce blood-born transmission of human immunodeficiency virus (HIV) and hepatitis C virus. OBJECTIVE: Manual magnetic particle-based extraction methods for HIV and HCV vir

30. Rabies virus in a pregnant naturally infected southern yellow bat (Lasiurus ega)
Current knowledge on bat lyssavirus infections in their native hosts is limited and little is known about the virulence, virus dissemination and transmission among free-living insectivorous bats. The present study is a brief description of rabies virus (RABV) dissemination in tissues of a naturally infected pregnant southern yellow bat (Lasiurus ega) and its

31. Evaluation of reference genes for real-time PCR studies of Brazilian Somalis sheep infected by gastrointestinal nematodes.
Precise normalization with reference genes is necessary, in order to obtain reliable relative expression data in response to gastrointestinal nematode infection. By using sheep from temperate regions as models, three reference genes, viz., ribosomal protein LO (RPLO), glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and succinate dehydrogenase complex subuni

32. Serologic evidence of the recent circulation of Saint Louis encephalitis virus and high prevalence of equine encephalitis viruses in horses in the Nhecolândia sub-region in South Pantanal, Central-West Brazil.
As in humans, sub-clinical infection by arboviruses in domestic animals is common; however, its detection only occurs during epizootics and the silent circulation of some arboviruses may remain undetected. The objective of the present paper was to assess the current circulation of arboviruses in the Nhecolândia sub-region of South Pantanal, Brazil. Sera fro

33. Análise molecular parcial dos genes VP1 e VP2 do vírus da doença infecciosa da bursa isolados no Brasil / Analysis on partial sequence of VP1 and VP2 genes of the Brazilian infectious bursal disease virus isolated in Brazil
A doença infecciosa da bursa (IBD), denominada também doença de Gumboro, é uma doença aguda, imunossupressora, altamente contagiosa de aves jovens e de grande importância econômica para a avicultura. O vírus da doença infecciosa da bursa (IBDV), sorotipo 1, pode ser classificado de acordo com sua antigenicidade e patogenicidade em amostras clássica

35. Molecular cloning and analysis of Myc modulator 1 (Mm-1) from Bufo gargarizans (Amphibia: Anura)
The protein of Myc modulator 1 (Mm-1) has been reported to repress the transcriptional activity of the proto-oncogene c-Myc in humans. Moreover, it was shown to be the subunit 5 of human prefoldin (PFD). So far, this gene and its homologs have been isolated and sequenced in many organisms, such as mammals and fish, but has not been sequenced for any amphibia

36. Intermittent HIV-1 viremia (blips) and virologic failure in patients under antiretroviral therapy: incidence and associated factors / Escape transitório da viremia plasmática de HIV-1 e falência virológica em indivíduos sob terapêutica anti-retroviral: incidência e fatores associados
INTRODUÇÃO: Pacientes em terapia anti-retroviral podem apresentar escapes transitórios de viremia plasmática (blip), porém os preditores desse evento e seu impacto sobre a incidência de falência virológica são ainda controversos na literatura. Neste estudo de coorte estimou-se a incidência de blip e de falência virológica e investigaram-se possí
