Impact of diversity of Mycoplasma hyopneumoniae strains on lung lesions in slaughter pigs
The importance of diversity of Mycoplasma hyopneumoniae (M. hyopneumoniae) strains is not yet fully known. This study investigated the genetic diversity of M. hyopneumoniae strains in ten pig herds, and assessed associations between the presence of different strains of M. hyopneumoniae and lung lesions at slaughter. Within each herd, three batches of slaughter pigs were investigated. At slaught...
متن کاملEffects of Mycoplasma hyopneumoniae vaccination in pigs co-infected with M hyopneumoniae and porcine circovirus
Materials and methods: Weaned pigs (n = 296) were each vaccinated with one of three M hyo bacterins or a placebo and challenged 3 and 5 weeks after the second vaccination with M hyo and PCV2, respectively. A subset of pigs, necropsied 2 or 4 weeks after PCV2 challenge, were evaluated for clinical signs, lesions, PCV2 serum levels, and M hyo in bronchial alveolar lavage fluids. Antibody titers t...
متن کاملIn vitro susceptibilities of Mycoplasma hyopneumoniae field isolates.
The in vitro susceptibilities of 21 Mycoplasma hyopneumoniae field isolates were determined using a broth microdilution technique. One isolate showed acquired resistance to lincomycin, tilmicosin, and tylosin, while five isolates were resistant to flumequine and enrofloxacin. Acquired resistance against these antimicrobials in M. hyopneumoniae field isolates was not reported previously.
متن کاملArbitrarily primed PCR analysis of Mycoplasma hyopneumoniae field isolates demonstrates genetic heterogeneity.
Mycoplasma hyopneumoniae is the primary agent of mycoplasmal pneumonia in swine. In this study we performed an arbitrarily primed PCR (AP-PCR) analysis, in which low-stringency amplification with a single primer was used, to investigate genetic variability in M. hyopneumoniae strains and field isolates. We performed preliminary experiments to examine the efficacy of 40 different 10-mer oligonuc...
متن کاملDiagnosis of Mycoplasma hyopneumoniae.
Mycoplasma hyopneumoniae, the cause of enzootic pneumonia, remains an important pathogen in the swine industry. This small, complex organism colonizes the ciliated cells of the respiratory tract, resulting in little exposure to the immune system. Confirming the presence of M. hyopneumoniae, as well as identifying its role in respiratory disease and pneumonia, remains challenging to the veterina...
