Mycoplasma Dispar As a Causative Agent in Pneumonia of Calves
Mycoplasma dispar som årsag til pneumoni hos kalve.
Acta Veterinaria Scandinavica volume 21, pages 34–42 (1980)
Abstract
Three field strains of Mycoplasma dispar were inoculated, by aerosol inhalation, into a total of eight naturally-born, colostrum-deprived calves. All three strains produced macroscopic pneumonia, each in one calf. Histopaithologically an exudative bronchitis accompanied by moderate interstitial cell proliferations was found.
Reisolation studies indicated that the entire respiratory tract is the natural habitat of Mycoplasma dispar, which apparently does not spread via the blood stream.
Sammendrag
Tre nyisolerede stammer af Mycoplasma dispar blev brugt til podningsforsøg pÃ¥ ialt 8 kalve, som straks efter fødselen blev isoleret og opdrsettet uden brug af kolostrum. Podningen blev foretaget ved inhalatÃon af mykoplasmer i aerosol.
Ved obduktionen fandtes for hver af de 3 stammers vedkommende 1 kalv med makroskopiske tegn på pneumoni. De histopatologiske forandringer var domineret af en eksudativ bronkitis ledsaget af modérate interstitielle celleproliferationer.
For alle 8 kalves vedkommende viste hyppigheden med hvilken reisolationsforsøgene lykkedes, at såvel øvre som nedre luftveje må anses for det naturlige habitat for Mycoplasma dispar, samt at denne rnykoplasmaart ikke synes at spredes i organismen via blodbanerns.
