چکیده

A lymphocyte blastogenesis inhibitory factor, (LBIF), was purified from the culture supernatant of human histiocytic lymphoma U937 by fast protein liquid chromatography. In this study, we demonstrated, first, that LBIF originated from a mycoplasma, Mycoplasma arginini, infecting U937 cells, and second, that LBIF bore the arginine deiminase activity. The implication of in vivo immunosuppression induced by arginine-utilizing mycoplasma species is discussed.

Inhibition of human peripheral blood mononuclear cell proliferation by Streptococcus pyogenes cell extract is associated with arginine deiminase activity.

Streptococcus pyogenes (group A Streptococcus) cell extracts (CE) have a remarkably powerful and dose-dependent inhibitory effect on antigen, superantigen, or mitogen-stimulated human peripheral blood mononuclear cell (PBMC) proliferation in vitro. Purification of the inhibitory component present in S. pyogenes type M5 (Manfredo strain) CE by anion-exchange chromatography followed by gel filtra...

Serological comparison of five arginine-utilizing Mycoplasma species by two-dimensional immunoelectrophoresis.

Five arginine-utilizing, nonglycolytic Mycoplasma species were compared serologically by two dimensional immunoelectrophoresis. The survey included: Mycoplasma hominis, Mycoplasma arthritidis, Mycoplasma gateae, Mycoplasma gallinarum, and three strains of Mycoplasma arginini. Although the M. arginini strains showed strong cross-reactions, each strain produced a different antigenic profile which...

Characterisation of mycoplasmas isolated from genital tract infections of sheep in Nigeria.

Four mycoplasma-like organisms isolated from ewes with mucopurulent vaginal discharge and swollen vulva were characterised. Biochemical tests showed three of the isolates to be negative for glucose fermentation and arginine hydrolysis, while the remaining isolate was negative for glucose fermentation but hydrolysed arginine. Serological identification using the growth inhibition, growth precipi...

Reconstitution of an active arginine deiminase pathway in Mycoplasma pneumoniae M129.

Some species of the genus Mycoplasma code for the arginine deiminase pathway (ADI), which enables these bacteria to produce ATP from arginine by the successive reaction of three enzymes: arginine deiminase (ArcA), ornithine carbamoyltransferase (ArcB), and carbamate kinase (ArcC). It so far appears that independently isolated strains of Mycoplasma pneumoniae encode an almost identical truncated...
