1. Factors affecting the performance of Pantaneiro horses
ABSTRACT This study aimed to assess the physical performance of Pantaneiro horses with and without equine infectious anemia (EIA) under functional conditions of cattle management. The horses were subjected to a performance test and split into two groups according to a completely randomized design: animals were chosen from populations testing positive and neg

2. Anemia infecciosa equina na Ilha de Marajó na foz do Rio Amazonas
Resumo: A anemia infecciosa equina (EIA) é uma importante enfermidade, transmissível e incurável causada por um lentivírus, equine infectious anemia vírus (EIAV), e não há relatos na literatura desta infecção em equinos da Ilha de Marajó. O objetivo deste estudo foi diagnosticar a anemia infecciosa equina nos municípios de Cachoeira do Arari, Salv

3. Anemia infecciosa equina: epizootiologia, prevencao e controle no Pantanal.
Os equideos sao ferramentas de trabalho essenciais a mais importante atividade economica do Pantanal - a pecuaria de corte, a qual e desenvolvida extensivamente na regiao. A Anemia Infecciosa Equina (AIE), conhecida mundialmente como Febre-do-pantano, e considerada uma das principais doencas que acometem equideos no Pantanal. Durante seis anos, entre 1990 e

4. Comparação da IDGA, ELISA e nested PCR no diagnóstico da anemia infecciosa eqüina em eqüinos, Asininos e Muares.
A lot of studies about horses (Equus caballus) immune responses to equine infectious anemia virus (EIAV) have been done all over the world, but there are little information concerning immune responses of mule (Equus caballus X Equus asinus) and donkey (Equus asinus) to natural infection with EIAV. The aim of this work was to compare the serological and virus

5. The equine thymic microenvironment: morphologic characteristics in normal or carrying animals of equine infectious anemia. / O microambiente tímico eqüino : características morfológicas em animais normais ou portadores de anemia infecciosa eqüina.
Neste trabalho, estudamos timos de equinos, incluindo aspectos morfológicos e o microambiente tímico em fetos, animais normais após o nascimento, e eqüinos com Anemia Infecciosa Eqüina (AIE). Utilizamos 64 animais em diferentes idades. Os timos foram analisados por técnicas histológicas, imunohistoquímica para detecção de proteínas de matriz extra

6. Leukocyte cytotoxicity in a persistent virus infection: presence of direct cytotoxicity but absence of antibody-dependent cellular cytotoxicity in horses infected with equine infectious anemia virus.
Antibody-dependent cellular cytotoxicity and direct cytotoxicity assays were performed with equine infectious anemia virus-infected target cells, equine leukocytes, and equine anti-equine infectious anemia virus antibody to determine whether these mechanisms play a role in controlling viral replication in equine infectious anemia. Direct cytotoxicity was obs

7. Equine infectious anemia virus replication is upregulated during differentiation of blood monocytes from acutely infected horses.
Equine infectious anemia virus is a lentivirus that replicates in mature tissue macrophages of horses. Ponies were infected with equine infectious anemia virus. During febrile episodes, proviral DNA was detectable, but viral mRNA was not detectable. As cultured blood monocytes from these ponies differentiated into macrophages, viral expression was upregulate

8. Quantitation of Immunoglobulin-Bearing Lymphocytes and Lymphocyte Response to Mitogens in Horses Persistently Infected by Equine Infectious Anemia Virus
A defect in lymphocyte function could be responsible for persistent infection by the equine infectious anemia virus. The number of lymphocytes bearing surface immunoglobulin, as detected by immunofluorescence, and lymphocyte response to mitogens were the same in uninfected and equine infectious anemia-infected animals. A defect in T or B lymphocyte numbers o

9. Equine Infectious Anemia Virus from Infected Horse Serum
Equine infectious anemia virus was purified from infected horse serum samples. Electron microscope observation on negatively stained preparations of purified virus showed roughly spherical particles sized between 100 and 200 nm in diameter. In disrupted particles, an envelope was visible but no internal structure could be resolved. Since the purified virus f

10. Antigenic stimulation of T lymphocytes in chronic nononcogenic retrovirus infection: equine infectious anemia.
Equine infectious anemia is a chronic disease of horses caused by a nononcogenic retrovirus. Studies were undertaken to determine the types of cells involved in the in vitro lymphoproliferative response to viral antigens and the dynamics of this reaction. It was observed that reactive lymphocytes were present at unpredictable times in the peripheral blood of

11. cis- and trans-acting regulation of gene expression of equine infectious anemia virus.
Deletion analysis of the equine infectious anemia virus long terminal repeat revealed that sequences responsive to virus-specific transactivation are located within the region spanning the transcriptional start site (-31 to +22). In addition, an active exon of a trans-acting factor (tat) was identified downstream of pol and overlapping env (nucleotides 5264

12. Monocyte activation in horses persistently infected with equine infectious anemia virus.
The monocytes of horses infected with equine infectious anemia virus were shown by their failure to migrate from capillary tubes and their increased adherence to erythrocytes to be activated.
