Effect of Disinfectants with Different Active Ingredients on Biofilm Formation in Pseudomonas aeruginosa.

We compared the effects of disinfectants on biofilms of 10 Pseudomonas aeruginosa strains isolated from different loci of patients with purulent-septic infections. Identification was carried out by standard bacteriological methods. To substantiate the prospects of using in hospitals and to assess the effect of disinfectants on P.

Simulation of bacterial biofilms and estimation of the sensitivity of healthcare-associated infection pathogens to bactericide Sekusept active.

The effect of bactericide Sekusept active (B SA), a peracetic acid-based preparation, on microbial strains, isolated from patients with severe infectious diseases who were treated in a regional children's multi-specialty hospital, was studied. Based on the biochemical identification, the strains were classified as gram-negative non-fermenting bacteria (22 strains), Enterobacteriaceae family (18 strains), and bacilli - 3 strains. The biocidal activity of B SA was evaluated by the degree of inhibition of the growth of bacterial cells, existing in the planktonic form and in the form of biofilm (on a flat-bottomed plastic immunological tablet).

[Impact of specific antituberculosis therapy on gastrointestinal tract in children].

Forty eight children aged 3 to 14 years treated at hospital for various tuberculous abnormalities were examined. The findings suggest that the use of antituberculosis agents in children with normal acid and pepsin production failed to have a noticeable effect on the gastrointestinal tract. Moreover, the 6-month use of highly and moderately effective antituberculosis agents produced no effect on the aggressive properties of gastric juice.
