Respiratory infections caused by bacterial agents in cattle and sheep in the Province of Corrientes, Argentina

Mannheimia haemolytica, Trueperella pyogenes and Pasteurella multocida are commensal bacteria of the upper respiratory tract of ruminants. However, in presence of predisposing factors, they can trigger the disease and even lead to death. The objective of this study was to determine the causes of mor...

However, in presence of predisposing factors, they can trigger the disease and even lead to death. The objective of this study was to determine the causes of morbidity and mortality in calves and lambs from 4 establishments located in the Province of Corrientes, Argentina. During of the period between June and August 2021, 4 cases of respiratory diseases were received at the INTA Mercedes, Corrientes, Animal Health Laboratory, both in cattle (3) and sheep (1). Incase of cattle, the morbidity in each the herd was 3.3% (5/150), 3.5% (7/200) and 12.4% (56/450). In the sheep flock, the morbidity was 8% (4/50). In sick animals, necropsies were performed and samples of lung and lung abscess were taken. In those samples, bacteriological culture and histological analysis were performed. Bacterial agents including T. pyogenes (1), M. haemolytica (2) and P. multocida (1) were detected, associated with the macroscopic findings and histological lesions. In our study, bacterial agents were detected as causing pneumonia represent in between 2 and 6% of mortality in the herds analyzed, so they should be considered as an important cause of death, in order to implement the necessary corrective and preventive measures. Mannheimia haemolytica, Trueperella pyogenes y Pasteurella multocida son bacterias comensales de las vías respiratorias superiores de los rumiantes. Sin embargo, cuando existen factores predisponentes pueden desencadenar enfermedades respiratorias o incluso ocasionar la muerte. El objetivo de este estudio fue determinar las causas de morbilidad y mortalidad en terneros y corderos de 4 establecimientos ubicados en la Provincia de Corrientes, Argentina. Durante los meses de junio a agosto de 2021 se recibieron en el laboratorio de Sanidad Animal del INTA Mercedes, Corrientes, 4 casos de enfermedades respiratorias, tanto en bovinos (3), como en ovinos (1). En el caso de los bovinos, los lotes presentaban una morbilidad de 3,3% (5/150), 3,5% (7/200) y 12,4% (56/450). Por su parte, el lote de ovinos expuestos contó con un 8% (4/50) de animales enfermos. Se realizó la necropsia de los ejemplares, tomando muestras de pulmón y en los casos que estuvieron disponibles, abscesos pulmonares. Con dichas muestras, se realizó el cultivo bacteriológico y análisis histológico. Mediante el cultivo bacteriológico se detectó la acción de T. pyogenes (1), M. haemolytica (2) y P. multocida (1) coincidente con los hallazgos macroscópicos y lesiones histológicas halladas. En nuestro estudio las neumonías por agentes bacterianos representaron entre el 2 y 6% de las causas de mortalidad de los rodeos analizados, por lo que deberían ser tenidas en cuenta como causante de muerte, a fin de implementar las maniobras correctivas y preventivas necesarias.
