Response of Swine to Mycoplasma hyopneumoniae Infection
Journal of Infectious Diseases, 1973Mycoplasmal pneumonia of swine offers a useful and economically significant model to study many aspects of chronic mycoplasmal pneumonia. Although the available information is very meager about areas of this disease, there are some very interesting aspects to this model. Infection with Mycoplasma hyopneumoniae is common in swine.

Evaluation of virulence of Mycoplasma hyopneumoniae field isolates
Veterinary Microbiology, 2003The course of enzootic pneumonia, caused by Mycoplasma hyopneumoniae, is strongly influenced by management and housing conditions. Other factors, including differences in virulence between M. hyopneumoniae strains, may also be involved. The aim of this study was to evaluate the virulence of six M.

Intraperitoneal vaccination of pigs to control Mycoplasma hyopneumoniae
Research in Veterinary Science, 1991In a field trial at a commercial piggery 22 pigs were vaccinated intraperitoneally, at 30 days and 60 days old, with formalin-killed Mycoplasma hyopneumoniae plus adjuvant. Two other groups of the same size, one receiving a ration containing antibiotics, were not vaccinated.

Survival analysis of two Mycoplasma hyopneumoniae eradication methods
Preventive Veterinary Medicine, 2020Mycoplasma hyopneumoniae is an important respiratory pathogen causing significant losses in the swine industry. Eradication of this bacterium from herds results in increased pig performance, productivity, and animal welfare. The objective of this study was to compare the time-to-detection of M. hyopneumoniae in breed-to-wean farms after the application

Aerosol vaccination of pigs against Mycoplasma hyopneumoniae infection
American Journal of Veterinary Research, 1993Summary Aerosol vaccination is used effectively to immunize poultry against Newcastle disease, but to the authors’ knowledge, this vaccination procedure is not well studied in other species. The efficacy of im and aerosol vaccination of pigs against Mycoplasma hyopneumoniae infection was evaluated.

Comparison of Mycoplasma hyopneumoniae strains by serologic methods
American Journal of Veterinary Research, 1983SUMMARY Six field strains of Mycoplasma hyopneumoniae isolated from pneumonic lungs of pigs, reference strains 11 and J of M hyopneumoniae, Ms 42 strain of Mycoplasma flocculare, and BTS 7 strain of Mycoplasma hyorhinis were compared serologically, using hyperimmune antisera produced in rabbits.

Interactions of Mycoplasma hyopneumoniae membranes with porcine lymphocytes
American Journal of Veterinary Research, 1991Summary Nonspecific mitogenicity of Mycoplasma hyopneumoniae membranes for blood lymphocytes (bl) and bronchial lymph node lymphocytes (lnl) from swine was investigated. Additionally, the influence of respiratory tract exposure to the same membrane preparation on responsiveness of these cells was evaluated.

Characteristics of protective activity of Mycoplasma hyopneumoniae vaccine
American Journal of Veterinary Research, 1984SUMMARY Protective activity of Mycoplasma hyopneumoniae vaccines prepared from whole cells or crude extracts was evaluated in an experimentally induced mycoplasmal pneumonia swine model. Swine were obtained at 7 to 10 weeks of age from a surgically derived herd free of porcine mycoplasmas.

A concise review of vaccines against Mycoplasma hyopneumoniae
Research in Veterinary Science, 2019Mycoplasma hyopneumoniae (Mhp) is the pathogen of Mycoplasmal pneumonia of swine (MPS), a chronic respiratory infectious discease which causes enormous losses to the swine industry worldwide. At present, vaccination is the most effective mean to prevent and reduce economic losses caused by this pathogen.

Gene expression signals in Mycoplasma hyopneumoniae and Mycoplasma capricolum.
Israel journal of medical sciences, 1987In Mycoplasma hyopneumoniae, the single genes for 16S and 23S rRNAs are clustered in one operon from which the 5S rRNA gene is separated by more than 4 kbp. This operon, gene 2413 and gene X from M. hyopneumoniae and the 5' ends of both rRNA operons from M. capricolum were cloned and used for analysis of the following gene expression signals: promoters
