In vitro tissue culture initiation from potted and garden Hydrangea macrophylla explants
Metka Šiško, 2016, izvirni znanstveni članek

Opis: The effect of sterilisation treatments on the initiation of the culture of three Hydrangea macrophylla genotypes in vitro was studied. The results indicated difference among different disinfection treatment; the consequence of treatments with dichloroisocyanuric acid, in combination with silver nitrate, was a significantly higher survival rate comparing to treatments based on NaOCl. Success of sterilisation was significantly influenced by studied genotypes. Two potted hydrangea genotypes (G2 and G3) showed higher survival rate (45.00 %, 55.00 %, respectively) comparing to the genotype 1 (originated from a local garden), which exhibited the highest percentage of contamination rate (58.75 %). Culturing the explants on a McCown woody plant medium supplemented with BAP at 2 mg/L and NAA at 0.005 mg/L produced the highest number of shoots with multiplication rate of 1.31 in 5 weeks. The highest rooting percentage (100.00 %) was obtained with the genotype 2 on a McCown woody plant medium supplemented with 0.5 mg/L IBA.

Hospital textiles, are they a possible vehicle for healthcare-associated infections?
Sabina Fijan, Sonja Šostar-Turk, 2012, pregledni znanstveni članek

Opis: Textiles are a common material in healthcare facilities; therefore it is important that they do not pose as a vehicle for the transfer of pathogens to patients or hospital workers. During the course of use hospital textiles become contaminated and laundering is necessary. Laundering of healthcare textiles is most commonly adequate, but in some instances, due to inappropriate disinfection or subsequent recontamination, the textiles may become a contaminated inanimate surface with the possibility to transfer pathogens. In this review we searched the published literature in order to answer four review questions: (1) Are there any reports on the survival of microorganisms on hospital textiles after laundering? (2) Are there any reports that indicate the presence of microorganisms on hospital textiles during use? (3) Are there any reports that microorganisms on textiles are a possible source infection of patients? (4) Are there any reports that microorganisms on textiles are a possible source infection for healthcare workers?

Antimicrobial disinfection effect of a laundering procedure for hospital textiles against various indicator bacteria and fungi using different substrates for simulating human excrements
Sabina Fijan, Srečko Koren, Avrelija Cencič, Sonja Šostar-Turk, 2007, izvirni znanstveni članek

Opis: Recent studies confirm the increase of nosocomial infections and microbial resistance. One of the possible causes is infected textiles due to inappropriate laundering procedures. Most Slovenian laundries use thermal laundering procedures with high energy and water consumption to disinfect hospital textiles. In addition to this fact, there is an increasing number of hospital textiles composed of cotton/polyester blends that cannot endure high temperatures of thermal disinfection. On the other hand, decreasing the temperature of laundering procedures enhances the possibility of pathogenic microorganisms to survive the laundering procedure. In our research, we determined the antimicrobic laundering effect by simulating a common laundering procedure for hospital textiles in the laboratory washing machine at different temperatures by the use of bioindicators. Enterococcus faecium, Staphylococcus aureus, Mycobacterium terrae, Enterobacter aerogenes, and Pseudomonas aeruginosa were used for determining the antibacterial laundering effect. Candida albicans was used for determining the antifungal laundering effect. Swine blood, artificial sweat, and swine fat were used as substrates for simulating human excrements and were inoculated together with the chosen microorganisms onto cotton pieces to simulate real laundering conditions. It was found that E. faecium, S. aureus, E. aerogenes, and P. aeruginosa survivedat 60 °C, but no microorganisms were found at 75 °C.
