Shedding of lawsonia intracellularis by fattening pigs in two production systems in Yucatan, Mexico
A longitudinal study was carried out to determine the frequency and incidence of Lawsonia intracellularis in fattening pigs in a one-site farm and a multi-site farm in Yucatan, Mexico. Fifty-nine and 58 pigs negative to L. intracellularis from the one-site farm and the multi-site farm were used, respectively. Pigs were monitored every 14 days from weeks, one to 21 of age. The bacterium in faeces was detected by PCR test. All pigs from both farms shed L. intracellularis at least once by week 11 of age; the greatest number of positive pigs were detected at week 7. The cumulative incidence was 100% in both farms and the incidence density rates in the one-site farm and the multi-site farm were 0.31 and 0.26 pigs per each 14-days, respectively. The result of this study gives some information for the implementation of schemes of prevention, control and eradication of L. intracellularis.
