25. Parâmetros utilizados na avaliação do sêmen congelado ovino para inseminação laparoscópica
Com a finalidade de verificar o valor de alguns atributos para avaliação da qualidade do sêmen congelado, através da prenhez, duzentas e noventa e sete ovelhas da raça Corriedale foram inseminadas, intra-uterinamente, por laparoscopia. Utilizou-se cio sincronizado, com pessários vaginais contendo 50 mg de MAP (acetato de medroxiprogesterona), por 12 di

26. Detection of equine arteritis virus in the semen of carrier stallions by using a sensitive nested PCR assay.
A nested PCR, developed for the detection of equine arteritis virus (EAV) in semen, detected less than 2.5 PFU of EAV per ml of naturally infected seminal plasma. Based on results from testing 88 semen samples from 70 stallions, the sensitivity and specificity of the test were 100 and 97%, respectively.

27. Sexual and in-contact transmission of asinine strain of equine arteritis virus among donkeys.
Two in a group of five naturally seropositive donkey stallions were found to shed equine arteritis virus (EAV) in their semen as demonstrated by virus isolation. Direct intramuscular inoculation of sonicated semen from one virus-shedding stallion (S3) caused clinical disease in two donkeys from which virus was recovered and in which seroconversion was detect

28. Detection of equine arteritis virus following amplification of structural and nonstructural viral genes by reverse transcription-PCR.
A reverse transcription (RT)-PCR assay was developed for the detection of equine arteritis virus (EAV) in cell culture supernatant and in horse semen. Four different sets of oligonucleotide primers complementary to sequences located in the 3' end of the polymerase gene (open reading frame [ORF] 1b) and to sequences representing the entire ORFs 3, 4, and 7, w

29. Genetic Divergence with Emergence of Novel Phenotypic Variants of Equine Arteritis Virus during Persistent Infection of Stallions
The persistently infected carrier stallion is the critical natural reservoir of equine arteritis virus (EAV), as venereal infection of mares frequently occurs after breeding to such stallions. Two Thoroughbred stallions that were infected during the 1984 outbreak of equine viral arteritis in central Kentucky subsequently became long-term EAV carriers. EAV ge
