Oral mycoplasmas in Sjögren's syndrome.
Mycoplasmas were sought in the salivary secretions and minor salivary gland tissue of 26 patients with Sjögren's syndrome or the allied sicca complex. A mycoplasma (M. orale type 1) was recovered from the stimulated parotid saliva of only one case. Possible mechanisms of mycoplasmal cell damage in this and allied disorders are considered and some future lines of investigation are suggested.
متن کاملMycoplasmas and recurrent oral ulceration.
A controlled cultural and serological investigation of mycoplasmas in recurrent oral ulceration was undertaken. No evidence for an aetiological relationship between oral mycoplasmas and this condition was obtained.Mycoplasmas, principally M. orale, were frequently recovered from the oral cavities of individuals with natural teeth, but rarely from edentulous subjects.

15 صفحه اولOrigins of the mycoplasmas: sterol-nonrequiring mycoplasmas evolved from streptococci.
We report the establishment of a phylogenetic relationship between the sterol-nonrequiring mycoplasmas (Acholeplasma species) and streptococci. Three specific antisera prepared against purified Streptococcus faecalis fructose diphosphate aldolase and glyceraldehyde-3-phosphate dehydrogenase and Pediococcus cerevisiae glyceraldehyde-3-phosphate dehydrogenase were used for comparative enzyme immu...
متن کاملSurvival of frozen mycoplasmas.
Cooling to -70 C killed a higher percentage of Acholeplasma laidlawii and Mycoplasma mycoides var. capri cells than cooling to -20 C. However, to preserve cell viability for prolonged periods storage at -70 C was much more preferable. The percentage of cells surviving freezing could be increased by increasing the initial cell concentration or by the addition of dimethyl sulfoxide or glycerol as...
