Pathogenesis of Mycoplasmal Pneumonia in Swine

American Journal of Veterinary Research, 1972
SUMMARY Twenty-nine hysterectomy-derived, colostrum-deprived (hdcd) pigs experimentally inoculated with the Nebraska isolate of Mycoplasma hyopneumoniae were killed in serial sequence to determine the progression of lesions. Two pigs were used as controls.

Evaluation of tiamulin for treatment of mycoplasmal pneumonia in swine

Journal of the American Veterinary Medical Association, 1988
Summary During 3 trials, using affected pigs of various ages, tiamulin was evaluated for treatment of experimentally induced mycoplasmal pneumonia. Pneumonia was induced in respiratory tract disease-free swine by intratracheal inoculation of a lung homogenate containing Mycoplasma hyopneumoniae. Eleven days after inoculation, when more than 20% of pigs

Mycoplasmal Pneumonia of Swine: Serologic Response in Pigs

American Journal of Veterinary Research, 1972
SUMMARY Pigs experimentally exposed to Mycoplasma hyopneumoniae developed antibody titers detectable by indirect hemagglutination (iha) test 2 to 3 weeks after exposure. These titers reached a maximal level on the 8th to 11th week and remained there until the 28th week.

Mycoplasmal Pneumonia of Swine: Active and Passive Immunizations

American Journal of Veterinary Research, 1971
SUMMARY Five vaccinal preparations were evaluated in pigs for their ability to prevent mycoplasmal pneumonia of swine (mps). Vaccine A protected 4 of 4 pigs from pneumonia; vaccines F and G conferred immunity to 34 of 44 pigs. Vaccine B protected 5 of 8 pigs from pneumonia, whereas none of the 3 pigs given vaccine H were protected.

Mycoplasmal Pneumonia of Swine: Development of an Indirect Hemagglutination Test

American Journal of Veterinary Research, 1971
SUMMARY An indirect hemagglutination (iha) test for the detection of antibodies to Mycoplasma hyopneumoniae in swine has been developed. With the iha test, antibodies were detected in 57 of 62 (92%) experimentally inoculated pigs that had pneumonic lesions and in 3 of 8 pigs that failed to develop lesions.

Evaluation of Diagnostic Procedures for Detection of Mycoplasmal Pneumonia of Swine

Journal of the American Veterinary Medical Association, 1979
SUMMARY 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, 1984
SUMMARY 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.

Evaluation of the indirect hemagglutination assay as a practical serodiagnostic test for mycoplasmal pneumonia of swine

Veterinary Microbiology, 1984
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.

Seroepidemiology of mycoplasmal pneumonia of swine in Japan as surveyed by an enzyme-linked immunosorbent assay

Veterinary Microbiology, 1993
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.
