1. Yellow fever
Summary The yellow fever (YF) virus is a Flavivirus, transmitted by Haemagogus, Sabethes or Aedes aegypti mosquitoes. The disease is endemic in forest areas in Africa and Latin America leading to epizootics in monkeys that constitute the reservoir of the disease. There are two forms of YF: sylvatic, transmitted accidentally when approaching the forests, and

2. SEROLOGICAL DETECTION OF HEPATITIS A VIRUS IN FREE-RANGING NEOTROPICAL PRIMATES (Sapajus spp., Alouatta caraya) FROM THE PARANÁ RIVER BASIN, BRAZIL
Nonhuman primates are considered as the natural hosts of Hepatitis A virus (HAV), as well as other pathogens, and can serve as natural sentinels to investigate epizootics and endemic diseases that are of public health importance. During this study, blood samples were collected from 112 Neotropical primates (NTPs) (Sapajus nigritus and S. cay, n = 75; Alouatt

3. Frequency of histopathological changes in Howler monkeys ( Alouatta sp.) naturally infected with yellow fever virus in Brazil
Abstract: INTRODUCTION: Due to the importance that Howler monkeys have on the yellow fever (YF) epidemiological sylvatic cycle in Brazil, more accurate morphological diagnostic criteria needs to be established, especially considering the differences that may exist between the genera of Brazilian non-human primates (NHPs) involved in yellow fever virus (YFV)

4. Estudos para o desenvolvimento de metodologia da produção in vivo do fungo Neozygites floridana Weiser e Muma para controle do ácaro Tetrancychus urticae Koch / Studies for the methodology development of in vivo production of the fungus Neozygites floridana Weiser and Muma to control the mite Tetranychus urticae Koch
Uma das principais espécies de ácaro praga é o ácaro rajado, Tetranychus urticae. Um dos inimigos naturais mais importantes deste ácaro é o patógeno Neozygites floridana. Para viabilizar o uso deste patógeno através de liberações inoculativas, ainda são necessárias informações básicas para subsidiar o desenvolvimento de uma metodologia de pro

5. 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

7. Bioecological studies of Neozygites floridana (Entomophthorales: Neozygiteceae), the fungal pathogen of Tetranychus evansi (Acari: Tetranychidae) / Estudos bioecológicos de Neozygites floridana (Entomophthorales: Neozygitaceae) fungo patogênico de Tetranychus evansi (Acari: Tetranychidae)
The tomato red spider mite, Tetranychus evansi Baker and Pritchard is an important exotic pest of Solanaceae in Europe and Africa. It is suggested that this mite could have originated from South America, a region where it is not considered as an important pest. An important natural enemy of T. evansi in Brazil is the fungus Neozygites floridana Weiser and Mu

8. Vigilância de epizootias em primatas não humanos (PNH) como instrumento de monitoramento de arboviroses e outras viroses de interesse em saúde pública
Epizootics in wild animals can be considered important public health indicators, besides little used in epidemiological surveillance. Evaluation of non human primates (NHP), like ?sentinels animals?, was realized through this study in Porto Rico County region, upper Paraná River, including Paraná and Mato Grosso do Sul States, Brazil, between June/04 and A

9. Predicting the local dynamics of epizootic rabies among raccoons in the United States
Mathematical models have been developed to explore the population dynamics of viral diseases among wildlife. However, assessing the predictions stemming from these models with wildlife databases adequate in size and temporal duration is uncommon.

10. Coronavirus and Pasteurella Infections in Bovine Shipping Fever Pneumonia and Evans' Criteria for Causation
Respiratory tract infections with viruses and Pasteurella spp. were determined sequentially among 26 cattle that died during two severe epizootics of shipping fever pneumonia. Nasal swab and serum samples were collected prior to onset of the epizootics, during disease progression, and after death, when necropsies were performed and lung samples were collecte

12. Molecular epizootiology and evolution of vesicular stomatitis virus New Jersey.
Vesicular stomatitis virus (VSV) has been shown previously to be capable of undergoing rapid mutational change during sequential experimental infections in various tissue culture cell systems (J. Holland, K. Spindler, F. Horodyski, E. Grabau, S. Nichol, and S. Vandepol, Science 215:1577-1585, 1982). The present study was undertaken to determine the degree of
