dc.description.abstractEl complejo respiratorio porcino (PRC) es una enfermedad multifactorial y compleja en cerdos en crecimiento y finalización que causa grandes pérdidas en la industria porcina en todo el mundo. El objetivo de este estudio fue determinar los diferentes patrones neumónicos presentes por estudios morfológicos y establecer su gravedad en cerdos de engorde pertenecientes a una granja de la parte oriental de Colombia. Se colectaron muestras de pulmones y nódulos linfáticos de cerdos en la planta de beneficio. Estos pulmones fueron examinados por un profesional en patología externo para detectar lesiones craneoventrales de bronconeumonía (BN). De 1000 cerdos examinados, solo se recolectaron 153 muestras. Cincuenta y dos cerdos fueron seleccionados como controles porque no presentaban lesiones macroscópicas y ciento un cerdos fueron llamados casos porque presentaban lesiones craneoventrales neumónicas. Las lesiones histopatológicas revelaron en el grupo control la presencia de neumonía intersticial (NI) en el 59,62% de los casos, y dos patrones neumónicos combinados en el 19,23% de los casos (Neumonía Bronco-Intersticial y Neumonía Intersticial – NBI-NI). Cuando se estudió el grupo de casos, se identificaron múltiples patrones neumónicos. La combinación más frecuente de patrón microscópico fue Bronconeumonía Supurativa (BNS) y Neumonía Bronco-Intersticial (NBI) en el 57,43% de los casos estudiados (BNS-NBI), seguido de la combinación de tres patrones neumónicos Bronconeumonía Supurativa + Neumonía Broncointersticial + Neumonía Intersticial en el 26,73% de los casos (BNS-NBI-NI). Estos hallazgos sugirieron que ocurrieron múltiples interacciones entre los patógenos del Complejo Respiratorio Porcino (PRC) y con una gravedad variable entre ellos. Además, las lesiones detectadas en la planta de beneficio serían diferentes si se comparan con el examen histopatológico. Por lo tanto, los estudios histopatológicos ofrecieron una idea más precisa de las lesiones reales presentes cuando ocurre neumonía clínica. Se puede sugerir, que la Neumonía Bronco-Intersticial compatible con M. hyopneumoniae se encontró en la combinación más frecuente detectada en este estudio asociada con bacterias o agentes virales.

dc.description.abstractPorcine Respiratory Complex (PRC) is a multifactorial and complex disease in growing and finishing pigs that causes major losses in the pig industry throughout the world. The goal of this study was to determine the different pneumonic patterns present by morphological studies and to establish their severity in finishing pigs belonging to a farm from the eastern part of Colombia. Samples from lungs and lymphatic nodules were collected from pigs at the abattoir plant. These lungs were examined by a external pathological professional to detect craneoventral Bronchopneumonia (BP) lesions. Out of 1000 pigs examined, only from 153 samples were collected. Fifty-two pigs were taken as control because they do not have gross lesions and one hundred one pigs were called cases because they had pneumonic craneoventral lesions. The histopathological lesions revealed in the control group the presence of Interstitial Pneumonia (IP) in 59.62% of the cases, and two combined pneumonic patterns in 19.23% of the cases (Broncho-Interstitial Pneumonia and Interstitial Pneumonia - BIP-IP). When the group of cases was studied, multiple pneumonic patterns were identified. The most frequent combination of microscopic pattern was suppurative bronchopneumonia (BP) and Broncho-Interstitial pneumonia (BIP) in 57.43% of the studied cases (BP-BIP), followed by the combination of three pneumonic patterns suppurative bronchopneumonia + broncho-interstitial pneumonia + interstitial pneumonia in 26.73% of the cases (BP-BIP-IP). These findings suggested that multiple interactions occurred among Porcine Respiratory Complex (PRC) pathogens and the varying severity among them. In addition, the lesions detected at the slaughter plant would be different if compared to the histopathological examination. Therefore, the histopathological studies offered a more accurate idea of the real lesions present when clinical pneumonia occurs. It may suggest that broncho-interstitial pneumonia compatible with M. hyopneumoniae were found in the more frequent combination detected in this study associated with bacteria or viral agents.eng
