[AF, a new bacterial preparation based on lactobacilli and its biological properties]

A highly efficient bacterial composition "AF" which includes representatives of two genera of microorganisms Enterococcus faecium and Lactobacillus acidophilus has been created as a result of analysis of biological properties of a number of strains of lactic-acid bacteria. Their biological properties--antagonistic activity in respect to pathogenic and conditionally pathogenic microorganisms, ability to adhesion and function in the intestine, sensitivity to antibiotics, etc., have been studied in the laboratory conditions. Prospects of the use of the given composition in production of milk products of functional effects have been shown.

[The microbial cenosis of the tonsils in healthy children and in those frequently ill]

The microbial cenosis of tonsils has been studied in healthy and ailing children. It has been found out that Staphylococcus aureus and S. epidermidis, beta-hemolytic streptococcus, rarely gram-negative flora and candidae were most often isolated in the ailing children. Normal microflora of healthy children mainly included lactic acid bacteria whose level considerably decreased in ailing children that is most distinctly expressed in children with decompensated tonsillitis. To correct the disturbances in microbial cenosis during complex therapy we used lactobacteria to treat the nasopharynx with the suspension of these bacteria. Positive clinical effect with following positive results of bacteriological investigation has been obtained in all patients.
