ABSTRACT.
In November 2015, an abortion outbreak occurred in a commercial dairy herd of 650 Holstein cows in Florida department, Uruguay. Forty-five (45) cows aborted within 3 wk. Five fetuses were subjected to gross and microscopic pathologic examination, and microbiological testing. One fetus had fibrinous epicarditis and peritonitis, and neutrophilic bronchopneumonia. Campylobacter fetus subsp. venerealis was detected by direct immunofluorescence, isolated and identified by PCR and sequencing of the 16S rDNA in the abomasal fluid and/or lung. Histologic examination of two other fetuses revealed non-suppurative necrotizing encephalitis, lymphohistiocytic myositis and myocarditis, and lymphocytic interstitial nephritis. In these fetuses, N. caninum antigen was detected intralesionally by immunohistochemistry, and N. caninum DNA was amplified by PCR on formalin-fixed paraffin-embedded brain. Antibodies against N. caninum were detected by indirect immunofluorescence in 10 of 27 cows, with titers ranging from 1/200 to 1/3200. The results indicate that two abortigenic microorganisms may coexist and cause contemporaneous abortion in a herd. It is relevant to highlight the importance of performing multiple diagnostic tests in various aborted dams and fetuses from the same herd for the etiologic confirmation of bovine abortion syndrome.

RESUMEN.
En noviembre de 2015 ocurrió un brote de abortos en un hato lechero comercial de 650 vacas Holstein en el departamento de Florida, Uruguay. Cuarenta y cinco (45) vacas abortaron en un lapso de 3 semanas. Cinco fetos fueron sometidos a un examen patológico macro y microscópico y a pruebas microbiológicas. Un feto tenía epicarditis fibrinosa y peritonitis, así como bronconeumonía neutrofílica. Se detectó Campylobacter fetus subesp. venerealis utilizando inmunofluorescencia directa; se lo aisló e identificó mediante PCR y secuenciación del 16S rDNA en el líquido abomasal y en el pulmón. El examen histológico de otros dos fetos reveló encefalitis necrotizante no supurativa, miositis linfohistiocítica y miocarditis, y nefritis linfocítica intersticial. En estos fetos se detectó intralesionalmente el antígeno de N. caninum mediante análisis inmunohistoquímico, y se amplificó el ADN de N. caninum mediante PCR en tejido cerebral fijado con formalina y embebido en parafina. Se detectaron anticuerpos contra N. caninum mediante inmunofluorescencia indirecta en 10 de 27 vacas, con títulos de entre 1/200 y 1/3200. Los resultados indican que dos microorganismos abortígenos pueden coexistir y provocar abortos contemporáneos en un hato. Subrayamos la importancia de realizar pruebas diagnósticas múltiples en diversas madres abortadas y fetos del mismo hato para obtener una confirmación etiológica del síndrome de aborto bovino.

Abstract.
Two-step weaning with nose flaps is used to minimise the stress of weaning in beef calves. Farmers leave the nose flaps for 7–30 days, basing the period on practical considerations. Thus, the objective of this study was to compare the behavioural response of 6-month-old beef calves fitted with nose flaps during 7 or 21 days before permanent separation from the dam, or abruptly weaned. Angus · Hereford cow-calf pairs were assigned to: (1) calves fitted with nose flaps on Day –7 and permanently separated from their mothers on Day 0 (NF7), (2) calves fitted with nose flaps on Day –21 and permanently separated from their mothers on Day 0 (NF21), and (3) calves abruptly weaned on Day 0 (CON). Behaviours (standing, lying, walking pacing, grazing, ruminating and vocalisations) were recorded during 3 days before and 5 days after permanent separation from the dam. On Days 1–3, standing and grazing behaviours decreased, whereas walking, pacing and vocalising increased in CON calves but not in NF7 or NF21 calves. Control calves differed from NF7 and NF21 calves for all these behaviours. The two nose flap treatments differed only on Day 1, when the changes in the frequency of walking, lying and standing were smaller in NF7 than NF21 calves. In conclusion, nose flaps can be used for periods from 7 to 21 days before permanent separation from the dam, diminishing the behavioural indicators of distress provoked by weaning. |
