A unique, bifunctional site-specific DNA recombinase from Mycoplasma pulmonis

Comparison of mitogens from Mycoplasma pulmonis and Mycoplasma neurolyticum.

Studies on Mycoplasma pulmonis and Mycoplasma neurolyticum mitogenesis demonstrated that macrophages are not essential for the interactions of M. neurolyticum with B lymphocytes, whereas M. pulmonis that stimulates B and T lymphocytes depends on macrophages to fully exert its mitogenic effects. Membranes of both species carry the mitogenic as well as pathogenic potentials. However, M. neurolyti...

Serological heterogeneity of Mycoplasma pulmonis.

Gliding motility of Mycoplasma pulmonis.

The gliding movements of freshly isolated Mycoplasma pulmonis cells were observed and measured. The motile cells had a characteristic appearance, an average speed of 0.4 to 0.7 micron/s, and a maximum speed of 1 micron/s.

Experimental arthritis in mice with Mycoplasma pulmonis.

A Mycoplasma pulmonis strain, recovered from the arthritic joints of mice employed in the serial passage of a chemically induced tumor, was found to be arthritogenic for mice under experimental conditions. Some joint involvement occurred in all mice challenged intravenously with this strain, and M. pulmonis was recovered frequently from the enlarged joints. The arthritis was migratory, appearin...

Secretory immune responses to Mycoplasma pulmonis.

Formalinized Mycoplasma pulmonis, along with aluminum hydroxide as an adjuvant, was used to subcutaneously immunize rats in the vicinity of the salivary gland to examine the characteristics of the secretory immune response to this pathogen. The induction of specific antibody to this microorganism was detected in serum and the exocrine fluids, namely, saliva and lung lavage fluid. Both immunoglo...
