Summary
Epidemiological, Aethiological and Pathological Studies of Respiratory Disease in Lambs in the South of Spain.
Between 1991 and 1993, it was observed epidemiologically that respiratory disturbances in lambs are associated with high temperatures during the summer. The aethiological agent isolated is principally Mycoplasma ovipneumoniae; moreover, Actinobacillus pleuropneumoniae biovar A has been isolated in a high number of samples.
Histopathologically, an interstitital bronchopneumonia was the main lesional finding; this lesion is associated with previous mycoplasma infection.
Resumen
En este trabajo se realiza un estudio epidemiológico, etiológico y lesional de la afecciones respiratorias que afectan a los corderos criados de forma intensiva en el Sur de España.
Epidemiológicamente, se comprobó la estacionalidad de estos problemas respiratorios, asociándose al incremento de la temperatura ambiental durante la época estival. Mycoplasma ovipneumoniae fue el agente etiológico más frecuentemente aislado, seguido de Actinobacillus pleuropneumoniae biovar A.
Histopatológicamente, se comprobó el desarrollo de una bronconeumonía intersticial como la principal forma lesional asociada a estos procesos respiratorios, lo que indica una clara implicación de los micoplasmas en la iniciación de este tipo de patología.
