25. Species determination of Brazilian mammals implicated in the epidemiology of rabies based on the control region of mitochondrial DNA
Identification of animals that are decomposing or have been run over or burnt and cannot be visually identified is a problem in the surveillance and control of infectious diseases. Many of these animals are wild and represent a valuable source of information for epidemiologic research as they may be carriers of an infectious agent. This article discusses the

26. Hantaviruses as emergent zoonoses
Hantaviruses belong to the Bunyaviridae family, which consists of vector-borne viruses. These viruses can provoke two infection types: hemorrhagic fever with renal syndrome (HFRS) - which occurs in the Old World - and hantavirus cardiopulmonary syndrome (HCPS) - an emergent zoonosis that can be found in many countries of the western hemisphere. Rodents are h

27. Identificação e estudo da diversidade do papilomavírus associado a lesões cutâneas em bovinos
Papillomaviruses (PV) has a worldwide distribution and is recognized as an etiologic agent associated with several benign and malignant epithelia lesions in human and animals. The Papillomaviridae family is a highly heterogeneous group of viruses, which has 18 genera, and likely occurs in most mammals and birds. The PV genome is circular double-stranded DNA

28. Metodologia para gestão do risco da Síndrome de Taura no Brasil devido à importação de pós-larvas de camarão
Risk analysis is a science-based method to assist decision-makers make consistent and transparent arguments and decisions in face of uncertainty and natural variability. The concept of risk involves the likelihood of the occurrence of an adverse effect and the magnitude of its consequences. This study developed a methodology for qualitative risk assessment o

29. Prevalência e fatores de risco associados ao herpesvírus bovino 1 (BoHV-1) em rebanhos bovinos do estado do Paraná
O herpesvirus bovino tipo 1 (BoHV-1), agente etiológico da Rinotraqueite Infecciosa Bovina (IBR), e considerado um dos principais patogenos de bovinos sendo responsável por grandes prejuizos econômicos a exploração pecuária. Estudos sorológicos e etiológicos revelaram a presença e alta frequencia da enfermidade em rebanhos de grande parte do país,

30. Frequência de leucemia e imunodeficiência viral felina em uma população hospitalar
Retroviruses make up a family of RNA virus that includes many agents of veterinary importance. The transcriptase reverse enzyme allows viral RNA to serve as template for production of a double-stranted DNA provirus. This provirus is then inserted in to the host?s genome. Two feline retroviruses have been identified that may cause immunodeficiency syndrome ?

31. Rabies review: immunopathology, clinical aspects and treatment
Among the diseases of viral origin, rabies is unique in its distribution and range of victims since it can afflict all warm-blooded animals. The interaction between the virus and the host population has facilitated the survival of the disease. The rabies virus (RV) has not changed in any significant way and has been capable of taking advantage of conditions

32. Atividade antiviral de polissacarídeo e frações de agaricus brasiliensis contra o Herpevírus bovino tipo 1
Os produtos naturais constituem uma fonte inesgotável de substâncias com atividades farmacológicas promissoras, incluindo ação antiviral. Neste trabalho, foi avaliado o potencial antiviral do polissacarídeo (PLS) e frações de Agaricus brasiliensis na replicação do herpesvírus bovino tipo 1 (BHV-1) em células HEp-2. Foi demonstrado que o PLS e as

33. Susceptibilidade do camarÃo-rosa Farfantepenaeus subtilis (Perez-Farfante, 1967) ao vÃrus da infecÃÃo hipodermal e necrose hematopoiÃtica (IHHNV) / Susceptibility of shrimp pink Farfantepenaeus subtilis (Perez-Farfante, 1967) to virus infection hipodermal and haematopoietic necrosis (IHHNV)
Diseases are the main biological factor that can limit and discourage the shrimp culture worldwide. Virus infection is the main cause of impact and economic losses registered in this sector. The Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) occurs in both wild and cultured shrimp, mainly in the juvenile and sub-adult phases, although it does

35. Doenças de Newcastle: padronização de testes sorológicos para o diagnostico em avestruzes (Struthio Camelus) e avaliação soroepidemiológica nos Estados da Bahia e de São Paulo.
Newcastle Disease is a highly contagious viral infection, which attacks several avian species, and represents one of the most important diseases for the modern poultry industry. Because of the relevance of the poultry industry in Brazil and the boom in ostrich rearing, it?s necessary the development of control strategies and it depends on the development of

36. Neurovirulence of murine coronavirus JHM temperature-sensitive mutants in rats.
The murine coronavirus strain JHM is highly neurotropic in rats and has a marked tendency to cause demyelinating central nervous system diseases after intracerebral inoculation. The clinical diseases observed range from an acute encephalomyelitis occurring within 2 weeks postinfection to a subacute demyelinating encephalomyelitis developing several weeks or
