Evaluation of Diagnostic Procedures for Detection of Mycoplasmal Pneumonia of Swine
Journal of the American Veterinary Medical Association, 1979SUMMARY The complement-fixation test (cft), a latex-agglutination test (lat), and Mycoplasma hyopneumoniae isolation procedures were compared with gross and microscopic lung evaluations for the routine diagnosis of mycoplasmal pneumonia (mp) of swine. The difficulty and variability of M hyopneumoniae isolation rendered this technique unacceptable.

Diagnosis of mycoplasmal pneumonia of swine: Sequential study by direct immunofluorescence
American Journal of Veterinary Research, 1984SUMMARY An improved direct fluorescent antibody test was evaluated for specificity and efficacy in diagnosing mycoplasmal pneumonia of swine. A sequential study was carried out in which pigs inoculated with a pneumonic lung suspension containing Mycoplasma hyopneumoniae strain 11 were euthanatized at postinoculation (pi) weeks 2 to 12.

Failure of lungworm-larvae-infected earthworms to transmit mycoplasmal pneumonia to swine
Veterinary Microbiology, 1976Abstract Two herds of swine, believed to be free from mycoplasmal pneumonia of swine (MPS) based upon negative Mycoplasma hyopneumoniae microtiter complement fixation test (CFT) results, subsequently exhibited clinical signs of MPS. Lungworms ( Metastrongylus spp.) were common to both herds.

Sera from swine experimentally or naturally infected with Mycoplasma hyopneumoniae (the etiological agent of mycoplasmal pneumonia of swine, MPS) were tested by the indirect hemagglutination assay (IHA), the enzyme-linked immunosorbent assay (ELISA) and the complement fixation (CF) test.

Antibodies to Mycoplasma hyopneumoniae were surveyed by enzyme-linked immunosorbent assay (ELISA) on serum, colostrum and milk samples collected from sows and on sera of growing/finishing pigs in Japan. Only one of 196 specific-pathogen-free sows induced a low ELISA value, while 72% of 411 sows from conventional herds were seropositive.

Erysipelothrix rhusiopathiae Koganei 65-0.15 strain, the live swine erysipelas vaccine for subcutaneous injection, has been shown to colonize the tonsils of pigs after oral inoculation. We thus evaluated the possible use of the strain as a vector for oral vaccination against mycoplasmal pneumonia of swine. Recombinant E.

AbstractThis study was conducted to evaluate immunological changes in peripheral blood leukocytes in pigs that were genetically selected for their improved resistance to mycoplasmal pneumonia of swine (MPS), usingMPSvaccine as an antigen. Twelve castratedMPS‐selectedLandrace pigs were compared with the same number of pigs from a nonselected line by ...

AbstractFive generations of Landrace pigs selected for average daily gain, backfat thickness, Mycoplasmal pneumonia of swine (MPS) lesion score, and plasma cortisol levels, was executed to decrease the MPS lesion score. Genetic parameters and correlated genetic responses for respiratory disease and peripheral blood immune traits were estimated in 1395 ...

SUMMARY AND CONCLUSIONS Standardized enzyme-linked immunosorbent assays for the serodiagnosis of mycoplasmal pneumonia of swine were developed, using the traditional Microtiter plate method and a method based on semiautomated processor-analyzer instrumentation. The results of the 2 procedures were not significantly different when the titers of positive

AbstractImmunogenic properties and mycoplasmal pneumonia of swine (MPS) lung lesions were compared between the immunity‐selected Large White line and the non‐selected Large White line. The selected Large White line showed a higher level of pulmonary MPS lesions compared with the non‐selected Large White line.
