[Sensitivity of Pseudomonas sp. strain isolated from distilled water to disinfectants]. / Wrazliwosc na srodki dezynfekcyjne szczepu Pseudomonas wyizolowanego z wody destylowanej.

The aim of the study was to compare Pseudomonas sp. strain isolated from distilled water and grown on the sterile filtrate from this water with the referent strain of Pseudomonas aeruginosa NCTC 6749 grown under the standard conditions, with the respect to their sensitivity to eight common disinfectants. Partly modified EN 1040 method was applied. The reduction factor (RF) for at least five concentrations of each of the products were determined. The linear relationship between concentration of the disinfectants and RF was established in a graphic form. Sensitivity of the strains was compared at the RF = 4. The WS strain was found to be more sensitivity than the referent strain to the disinfectants. The ratio concentrations of the solutions that were effective during 15 minutes against both the strains were; 1.3 for ethyl alcohol; 2.1 for glutaraldehyde; 1.7 for formalin; 1.85 for phenol. In the case of chloramine-T, the sodium salt of dichloroisocyanuric acid, and peracetic acid the ratios of concentrations were 156.0; 96.5 and 21.5 respectively. They indicate much higher sensitivity of the strain isolated from distilled water to these chemicals.

[The action of ultraviolet radiation on microorganisms found in air]. / Dzialanie promieniowania UV na drobnoustroje znajdujace sie w powietrzu.

The effect of a device with UV lamp on the microorganisms in the air was investigated. The air was continuously pumped through the device for 24 h. After that time the number of microorganisms was reduced by 0.3 log.

[The effect of growth media on recovery of test microorganisms after exposure to saturated steam under pressure]. / Wplyw podlozy wzrostowych na odzysk drobnoustrojów testowych poddanych dzialaniu pary wodnej w nadcisnieniu.

The aim of this study was to find out which growth media give the best condition for the development of test bacteria after exposure to saturated steam under pressure. The test organisms were strains of Bacillus subtilis NCTC 3610 and Bacillus stearothermophilus NCTC 8923. The test prepared from spore suspension were exposed to saturated steam under pressure 0.2 atn-B.subtilis, and 0.7 atn-B. stearothermophilus with various length of exposure /sublethal conditions/. After the exposure the tests were placed in growth media. The obtained results show that the compositions of the medium in which spore-forming bacteria are grown after the exposure under sublethal conditions to saturated steam under pressure affects the recovery of the test organism. The media with glucose, tryptose and L-alanine provided the best conditions for growth.

[Microbiological contamination of disinfectants used in hospitals for the disinfection of medical instruments. Part II: The estimation of sensitivity of isolated strains of bacteria in disinfectants]. / Zanieczyszczenie mikrobiologiczne plynów stosowanych w szpitalach do dezynfekcji narzedzi lekarskich. Czesc II. Okreslenie wrazliwosci wyizolowanych szczepów bakterii na srodki dezynfekcyjne.

The sensitivity, on basic disinfectants, of 30 strains of bacteria isolated from disinfecting fluid used in hospitals were estimated. The sensitivity of isolated strains were compared with that of laboratory test strains.

Repositioning the misplaced colostomy for high imperforate anus: report of a new technique.

The case of a 2-year-old boy with high imperforate anus and an incorrectly positioned colostomy (in the left upper quadrant of the abdomen) is presented. To relieve the resulting tension on the distal rectosigmoid colon and to allow for its use in a combined pull-through and posterior sagittal anorectoplasty, the colostomy was moved to the subumbilical area.

[The effect of temperature on bactericidal activity of certain disinfectants]. / Okreslenie wplywu temperatury na aktywnosc bakteriobójcza niektórych srodków dezynfekcyjnych.

Increase of the temperature by 10 degrees C (on the temperature range 22-32 degrees C) grows up the bactericidal activity of the disinfectants like Laurosept, Chloramine, Sterinol and Jodoseptan against E. coli and S. aureus. It has not observed the influence on the bactericidal activity of Septyl against S. aureus. Surface-active agents are more effective at higher temperature against S. aureus, phenolic disinfectants and Chloramine against E. coli.
