Equine alphaherpesvirus is a major pathogen that causes respiratory disorders, abortion, neurological syndromes, and perinatal mortality in horse populations worldwide. The aim of this study was to determine whether the occurrence of anti-alphaherpesvirus antibodies is correlated to reproductive abnormalities in horses in the state of Pernambuco, Brazil. The virus neutralization was carried out in 322 serological samples from unvaccinated horses from 42 farms located in 16 municipalities in the Microregion of the Vale do Ipojuca, Pernambuco, Brazil. Of these horses, 23.3% (75/322; 95% CI: 18.9-28.4%) were found to be reactive to anti-alphaherpesvirus antibodies. In addition, 61.9% (26/42) of farms had at least one reactive animal, with an inter-herd variation of 5% to 100%. With regard to reproductive rates, herpetic infection was associated with the use of biological reproductive techniques such as artificial insemination (AI) and embryo transfer (ET), which uses natural mating (p = 0.003); history of perinatal mortality (p = 0.004); birth interval greater than two years (p = 0.003); and reproductive seasonality of mares with irregular cycles in the herd (p = 0.041). This is the first report on the identification of horses reactive to anti-alphaherpesvirus antibody in the state of Pernambuco, Brazil. From the results obtained, the adoption of prophylactic measures such as vaccination is suggested in order to prevent infection in susceptible animals and to reduce the viral load excreted by animals with quiescent infection.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.

Communicative Effectiveness

Two methods of identifying language disordered children are examined. Traditional approaches require attention to relatively superficial morphological and surface syntactic criteria, such as, noun-verb agreement, tense marking, pluralization. More recently, however, language testers and others have turned to pragmatic criteria focussing on deeper aspects of meaning and communicative effectiveness, such as, general fluency, topic maintenance, specificity of referring terms. In this study, 54 regular K-5 teachers in two Albuquerque schools serving 1212 children were assigned on a roughly matched basis to one of two groups. Group S received in-service training using traditional surface criteria for referrals, while Group P received similar in-service training with pragmatic criteria. All referrals from both groups were reevaluated by a panel of judges following the state determined procedures for assignment to remedial programs. Teachers who were taught to use pragmatic criteria in identifying language disordered children identified significantly more children and were more often correct in their identification than teachers taught to use syntactic criteria. Both groups identified significantly fewer children as the grade level increased.
