LACK OF EVIDENCE OF TOXIGENIC P. MULTOCIDA IN A HERD WITH ATROPHIC RINITIS

摘要

Atrophic rinitis (AR) can cause important economic losses in fattening pigs (1). The etiologic agents of AR are toxigenic Pasteurella multocida (TPM) and Bordetella bronchiseptica (BB). The most prominent lesion is the hypoplasia of nasal turbinate bones. The extent and severity of the atrophy is greater with TPM than with BB. In most instances, the criterion to consider a farm free from the progressive form of AR is the absence of TPM. This a report of a case of AR in a farm formerly free from the disease where only BB was detected.
