Isolation of a cytopathic factor from Mycoplasma hyopneumoniae.
A cytopathic factor was isolated from M. hyopneumoniae VPP11 membranes. This factor had an isoelectric point of 6.2 and was capable of inducing cytopathic effect in MRC-5 human lung fibroblast culture at a concentration of 250 ng of protein per ml. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of this cytopathic factor showed a major band with a molecular weight of approximately 54,...
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...
متن کاملIntradermal vaccination for Mycoplasma hyopneumoniae
Results: Injection site reactions were minimal for all vaccines. Pigs vaccinated ID, either by needle or needleless injector, had significantly higher M hyopneumoniae antibody titers than did pigs vaccinated by IM injection. Pigs vaccinated by needleless ID injection had lower lung lesion scores and higher IgA and IgG titers in bronchoalveolar lavage fluid than did nonvaccinates following chall...
متن کاملIsolation of a highly cytopathic lentivirus from a nondomestic cat.
A feline immunodeficiency virus-like virus (FIV-Oma) isolated from a Pallas' cat (Otocolobus manul) is highly cytopathic in CrFK cells, in contrast to the chronic, noncytolytic infection established by an FIV isolate from a domestic cat (FIV-Fca). The virions have typical lentivirus morphology, density, and magnesium-dependent reverse transcriptase activity. The major core protein is antigenica...
متن کاملMycoplasma Hyopneumoniae - Epidemiology and Control
Respiratory disease is an economically devastating syndrome affecting swine production worldwide. Mycoplasma hyopneumoniae (M. hyo) is a key pathogen involved with enzootic pneumonia (EP) and the Porcine Respiratory Disease Complex (PRDC). Enzootic pneumonia is composed of M. hyo and secondary bacteria such as Pasteurella multocida, Streptococcus suis, Haemophilus parasuis, and Actinobacillus p...
