AB  - Actinobacillus pleuropneumoniae (App) is one of the most important swine respiratory
pathogens that causes porcine pleuropneumonia and massive financial losses in pig
industry. The objective of this study was to investigate App infection in five pig herds
from North Macedonia experiencing clinical respiratory infections by serological
testing and a slaughterhouse pleurisy evaluation system (SPES). In total, 250 blood
samples were taken from pigs aged 6, 10, 14, 18, and 22 weeks. Ten animals per age
category from each farm were sampled and analyzed for presence of antibodies against
App. At the slaughterhouse, 50 lungs per herd from slaughtered age pigs were scored
by the SPES for the presence of lesions associated with chronic pleurisy. The overall
seroprevalence to App was 65.6%, ranging from 34% to 98% at the farm level. The
highest seroprevalence was found in 6-week-old pigs in all farms, while significant
differences were observed between farms in the 10-, 14-, 18-, and 22-week-old pig groups. Pleurisy associated with App was found in 26.4% of all examined lungs, with
the mean SPES score being 0.75 (0.14 - 1.10). The percentage of SPES scores of 0, 1, 2,
3, and 4 in all lungs were 73.4%, 1.6%, 8.8%, 8.4%, and 7.6% respectively. A significant
difference in mean SPES score was obtained between two farms. High seroprevalences
of App detected on the tested farms were probably due to constant natural infection.
The highest seroprevalences, measured in the youngest pigs, could be due to maternallyderived antibodies. Higher seroprevalence against App and lower SPES scores in some
farms suggests immunity resulting from infection by corresponding field serotypes.
