Lymphocyte activation by various Mycoplasma strains and species.
The capacity of various mycoplasma strains and species to induce lymphocyte transformation in vitro was studied. Of six strains of Mycoplasma pulmonis studied, five displayed mitogenic activity with rat lymphocytes. Among those M. pulmonis strains, our MP15 isolate and the Negroni strain exhibited particularly potent mitogenic capacity. The murine mycoplasmas M. neurolyticum and M. arthritidis ...
متن کاملDifferences in incorporation of nucleic acid bases and nucleosides by various Mycoplasma and Acholeplasma species.
Eight species representative of the serological diversity of the Mycoplasmatales were tested for their ability to incorporate radiolabeled nucleic acid precursors into acid-insoluble material. Cultures in complex growth medium were centrifuged and resuspended in minimal essential medium (Eagle). For Acholeplasma laidlawii, labeling occurred mainly during the first 4 h of incubation, with substr...
متن کاملRequirements for lymphocyte activation by unusual strains of simian immunodeficiency virus.
When residues 17 and 18 in nef of simian immunodeficiency virus strain SIVmac239 were changed from RQ to YE, the resultant virus was able to replicate in peripheral blood mononuclear cell cultures without prior lymphocyte activation and without the addition of exogenous interleukin-2, caused extensive lymphocyte activation in these cultures, and produced an acute disease in rhesus and pigtail m...
متن کاملT-strains of mycoplasma and nongonococcal urethritis.
Since the isolation by Dienes and Esdall (1937) of a strain of Mycoplasma from a patient with a Bartholin's gland abscess, numerous attempts have been made to provide definite proof of the aetiological role of Mycoplasma in urogenital tract infections, especially nongonococcal urethritis (NGU). Most of the earlier studies were concerned with Mycoplasma hominis, but it now appears that this spec...
