1.  The genital Mycoplasma and Ureaplasma flora of healthy and diseased dogs. 
The genital mycoplasma and ureaplasma flora was compared in 136 dogs with varied reproductive histories. Mycoplasmas were recovered from 88% of vulvovaginal swabs, 85% preputial swabs and 72% semen samples. Isolation rates were slightly higher from dogs that were infertile or had evidence of genital disease but the differences from those that were fertile or clinically normal were statistically significant only in the male. Ureaplasmas were recovered from half the females sampled. Higher, but not statistically significant isolation rates (75%) were made from infertile females with purulent vulvar discharge versus those that were clinically normal and fertile (40%). In the male dog there was a significantly higher incidence of ureaplasmas in the prepuce of infertile animals (69%) than those that were fertile (0%) (p less than or equal to 0.05). Semen isolations although not significantly higher in infertile males, were all made from ejaculates, with subnormal motility, low sperm counts and/or a high percentage of midpiece and tail abnormalities (bent or tightly coiled).

2.  Synovial immunoglobulin and antibody in vaccinated and nonvaccinated calves challenged with Mycoplasma bovis. 
Intravenous injection of Mycoplasma bovis produced in calves arthritis with synovial infiltration of lymphocytes, macrophages and neutrophils. Necrosis was observed focally around blood vessels. Joint spaces contained fibrinopurulent exudate. Parenterally vaccinated calves had a markedly reduced frequency of arthritic joints. Immunoglobulin classes and specific antibody in joint fluids were quantitatively less than in sera but significantly greater in arthritic than in normal joints. The possible mechanisms of induction of joint fluid antibody are discussed.
