- Abstract
A search for the methods new in principle which should block and eliminate AIDS-associated mycoplasmas was carried out. This work was conducted in two ways: 1) inhibition of vital activity of Mycoplasma fermentans PG-18 and Acholeplasma laidlawii PG-8 by 6-azacytidine; 2) establishment of carbohydrate composition of receptors for these mycoplasmas aimed at the competitive elimination of these microorganisms from urogenital tract of a man using carbohydrates. It is established that a 50%-inhibiting concentration of 6-azacytidine was 23.4 micrograms/ml for M. fermentans PG-18 and 62.5 micrograms/ml for A. laidlawii PG-8. alpha-D-glucose and N-acetylneuramine acid are two terminal carbohydrates that can serve as receptors for M. fermentans on human mucous membranes while D-mannose and N-acetyl-D-glucosamine for A. laidlawii PG-8. alpha-D-glucose in concentration 75 mM and N-acetylneuramine acid in concentration 150 mM competitively inhibit reception of M. fermentans on mucosae, while D-mannose in concentration 150 mM and N-acetyl-D-glucosamine in concentration 75 mM are antireceptor substances for A. laidlawii.
