An abattoir survey of pneumonia and pleuritis in slaughter weight swine from 9 selected herds. I. Prevalence and morphological description of gross lung lesions
Abstract
The prevalence and pathomorphology of gross lung lesions were studied in 855 slaughter weight pigs from 9 selected herds in south-eastern Norway. Pneumonic or pleuritic lesions were found in 84% of the lungs, ranging from 37% in the least affected herd to 97% in the one most affected. Bronchopneumonia indicative of a primary Mycoplasma hyopneumoniae infection was found in 70% of the lungs, ranging from 9% to 82% in the individual herds. The amount of bronchopneumonic lesions in individual lungs ranged from 0 to 69%, with an average of 7.8%. Pleuropneumonia indicative of Actinobacillus (Haemophilus) pleuropneumoniae infection was found in 29% of the lungs ranging from 0 in the least affected herd to 58% in the most affected. Diffuse pleuritis was found in 41% of the lungs and the prevalence ranged from 4% to 63%.
Lunger fra 855 slaktegriser fra 9 utvalgte besetninger i sydøst-Norge ble samlet inn ved slakting og undersøkt med henblikk på pneumoni og pleuritt. Slike lesjoner ble funnet i 84 % av lungene. Frekvensen i de enkelte besetningene varierte fra 37 % til 97 %.
Bronkopneumoni som kunne tyde på primær Mycoplasma hyopneumoniae infeksjon ble funnet i 70 % av lungene. Frekvensen i de enkelte besetningene varierte fra 9 % til 82 %. Utbredelsen av bronkopneumoniske lesjoner i den enkelte lunge varierte fra 0 til 69 % med en gjennomsnittlig utbredelse på 7.8 %.
Pleuropneumoni som tydet på infeksjon med Actinobacillus (Haemophilus) pleuropneumoniae ble funnet i 29 % av lungene med variasjon fra 0 til 58 % i de enkelte besetningene. Diffus pleuritt ble funnet i 41 % av lungene. I de enkelte besetningene varierte denne frekvensen fra 4 % til 63 %.
