[Anaerobic nonclostridial soft-tissue infection].

Over the period 1985 through 1994, observations are conducted on forty-eight patients, 35 men and 13 women, with age ranging from 11 to 56 years, presenting anaerobic non-spore-forming infection of the soft tissues (necrotizing fasciitis (3), postinjection nonclostridial myositis (7), crepitant cellulitis in diabetic gangrene (21), neck phlegmon (5), perineal phlegmon (9), and progressive bacterial synergistic gangrene against the background of chronic osteomyelitis (3). Infection development is characterized by local necrotic processes, intoxication, crepitations, fetor, fever, and in part of the patients--septic shock and DIC syndrome. The microbiological study shows presence of anaerobes, as mono- and polyinfection, aerobic-anaerobic associations, and gram-negative aerobes--in one patient alone. Invariably, the general condition is rather serious. Lethality amounting to 12.5 percent is ascribed to the late detection and unspecified and inadequate treatment protocol in the initial period of observation. The treatment is complex: incisions with successive many-staged necrectomies, antibiotics, metronidazole, hyperbaric oxygenation and hemadsorption. If several (2-3) of the aforementioned symptoms are present, evidence of anaerobic flora should be mandatory and purposefully seeked.

[Anaerobic surgical infection].

The study covers 125 patients with anaerobic surgical infection, aged 7 to 82 years. Of the total 27 cases are operated for acute cholecystitis, four--diffuse acute peritonitis, seventeen--acute appendicitis, and three--acute hematogenous osteomyelitis. In acute cholecystitis and acute appendicitis microbiological study is carried out of the content, organic wall and periorganic space. In acute cholecystitis patients anaerobic flora is found in 39.01 per cent, and gram-negative--in 44.9 per cent, and in those presenting acute appendicitis--in 28.3 per cent and 58 per cent, respectively. The clinical analysis results point to a severer clinical course in the patients presenting anaerobic flora. The letter becomes manifest as mono infection in 37.2 per cent. It is pointed out that in the presence of two or more signs, characteristic of anaerobic infection, namely: destructive early process, offensive odor and intoxication, anaerobic bacterial flora should be invariably considered. At each microbiological examination the results of staining according to Gram should be also demanded from the laboratory.

[The effect of acetic acid and furfural on yeast growth].

Acetic acid and furfural are normal components of the yeast hydrolysates. The influence of acetic acid in different concentrations (from 2 to 10 g/dm3) and furfural (from 0.2 to 0.8 g/dm3) on the growth of 8 yeast strains from the genus Candida under cultivation in synthetic nutrient media has been studied. It was established that some yeast strains absorb acetic acid better at pH 4.0-5.0, while others--only at pH 6.0 and at different concentrations of the acid in the nutrient media. Acetic acid in concentrations from 2 to 4 g/dm3 suppresses growth entirely in some strains, while in others growth was established. Acetic acid in concentrations over 8 g/dm3 inhibits growth in all 8 strains of the studied yeasts. Furforal in concentration to 0.4 g/dm3 in the synthetic nutrient media inhibits the growth in the 8 strains to a certain extent, while in concentration over 8 g/dm3 it stops the growth in all 8 yeast strains.
