Mycoplasma hyorhinis in Taiwan: Diagnosis and isolation of swine pneumonia pathogen.
Veterinary Microbiology, 2006, Volume 115, N°1-3, 111-116
So far, Mycoplasma hyopneumoniae has been considered as the agent responsible for swine enzootic pneumonia (SEP) and Mycoplasma hyorhinis as a secondary respiratory pathogen more prone to cause polyserositis, growth retardation and reduced feed efficiency. The basic means of control for Mycoplasma hyorhinis infection do not include vaccines and only chemotherapy allows to minimize the economic loss due to M. hyorhinis infection. However, the study of swine pneumonia cases reported in Taiwan since 2001 shows that they are increasingly associated with M. hyorhinis infection while the detection of M. hyopneumoniae decreases and the rate of mixed infection remains unchanged. The intratracheal inoculation of three wild strains of M. hyorhinis (ATIT-1, -3, -7) to 6 pigs kept in a specific-pathogen-free environment and necropsied 28 days later led to typical mycoplasmal pneumonia lesions in two of them. M. hyorhinis seems thus to gain ground as pneumonia pathogen in swine in Taiwan.
