Description of an acute bovine pulmonary edema and emphysema outbreak in southwest cordoba, argentina
An acute bovine pulmonary edema and emphysema (ABPEE) outbreak observed in the southwest region of Cordoba province, Argentina is described. The outbreak occurred in spring 2004, in a cattle ranch located in Coronel Moldes, Departamento Río Cuarto, Argentina, under natural grazing conditions, involving Aberdeen Angus x Hereford crossed cows, ~3-5 years of age. The outbreak started after moving the animals from a range lot with scarce pasture, to different grassland with higher availability of the same forage, after a rainfall event. Mortality and lethality rates were 6.6 % and 55.5 %, respectively. Three days after arrival in the new grassland, one dead animal was found. On the next day, several animals suddenly showed respiratory distress with remarkable expiratory dyspnea. Major lesions at necropsy included distended (not collapsed) lungs, emphysema, and intense interstitial edema. These lesions were confirmed by histopathology, including type II hyperplasia and hyaline membranes. Successful, symptomatic treatment was given at condition onset to those cows with severe respiratory distress. It was concluded that the natural pasture on which cattle were grazing at outbreak start -mostly Cynodon dactylon and Cynodon hirsutus- could have caused this pathology.

Se describe un brote de enfisema y edema pulmonar agudo en bovinos de la zona Sur-Oeste de la provincia de Córdoba, Argentina. El brote se presentó en la primavera de 2004 en un establecimiento de cría bovina de la localidad de Coronel Moldes, Departamento Río Cuarto, bajo condiciones naturales de pastoreo. Los animales afectados fueron vacas mestizas cruza Aberdeen Angus x Hereford de aproximadamente entre 3 y 5 años de edad. El brote se desencadenó después de un cambio de una pradera de baja disponibilidad a otra con la misma base forrajera, pero con mayor oferta, después de una lluvia. La mortalidad por esta causa fue de 6.6 % y la letalidad de un 55.5 %. La afección se presenta al tercer día de haber ingresado al nuevo lote, con un animal muerto. Al día siguiente aparecen bruscamente varios animales con signos de severa dificultad respiratoria. Los bovinos afectados presentaban un severo estrés respiratorio con marcada disnea espiratoria. Las principales lesiones encontradas en la necropsia fueron pulmones distendidos (sin colapsar), enfisema y edema intersticial intenso en el tejido pulmonar, lo cual fue corroborado, histopatológicamente, encontrándose hiperplasia de neumocitos tipo II y membranas hialinas. Se practicó tratamiento sintomático al inicio del cuadro, en aquellas vacas que presentaban un severo estrés respiratorio, el cual resultó ser efectivo. Se concluyó que la pastura natural que estaban pastoreando al iniciarse el brote, conformada en su mayor proporción por Cynodon dactylon y Cynodon hirsutus podría ser la causante de esta patología.
