Catheter-associated urinary tract infections (CAUTIs), caused by biofilms, are the most frequent health-care associated infections. Novel antibiofilm coatings needed to increase catheters' life-span, decrease prevalence of CAUTIs and reduce development antimicrobial resistance. Herein, antibacterial zinc oxide nanoparticles (ZnO NPs) were decorated with a biofilm matrix-degrading enzyme amylase (AM) simultaneously deposited onto silicone catheters in one-step sonochemical process. The...
Catheter-associated urinary tract infections are the most common hospital-acquired and cause patient discomfort, increased morbidity, prolonged stays, altogether posing a huge burden on healthcare services. Colonization occurs upon insertion, or later by ascending microbes from rich periurethral flora, is therefore virtually unavoidable medical procedures. Importantly, dwell time significant risk factor for bacteriuria because it gives biofilms to develop mature. This why we engineer...
Catheter-associated urinary tract infections represent a major share of nosocomial infections, and are associated with longer periods hospitalization huge financial burden. Currently, there only handful commercial materials that reduce biofilm formation on catheters, mostly relying silver alloys. Therefore, we combined silver-phenolated lignin nanoparticles poly(carboxybetaine) zwitterions to build composite antibiotic-free coating bactericidal antifouling properties. Importantly, the...
Abstract Rabbits and rats were inoculated with material derived from FLK cells producing permanently bovine leukaemia virus (BLV). The viral presence in the inoculum was proved by transmission electron microscopy, immunofluorescence, immunogold labelling demonstrating Tax protein, PCR analysis. About 30 % of infected animals sustained BLV seropositivity during experiment, demonstrated symptoms lympholeukaemia - clinical manifestation an immunosuppressive condition, increased number...
The report deals with new results on the construction of a simple scanning tunnelling microscope (STM) for non-destructive studies atomic surface structure. mechanical and electronic scheme incorporate number novel features including full automatic coarse Z-motion several millimetres. A set elements data system, which have been developed to control microscope, are also discussed. performance STM is illustrated by presenting images thermally evaporated gold films ceramic substrates highly...
The effects of concomitant infection with chicken anaemia virus (CAV) on the incidence, clinical manifestation and mortality from leukosis, induced by avian myelocytomatosis strain Mc29 were studied. Experimental one-day-old 15 I line White Leghorn chickens inoculated simultaneously CAV or alone observed daily for signs mortality. Both groups in combination developed tumours died within 57 days. Necropsy has been performed all dead birds following standard protocol. Organ samples thymuses,...
