A modified method for rapid sterilisation of the fibrebronchoscope using immersion of the instrument in 0.1% benzalkonium chloride for five minutes followed by a further five minutes' immersion in 96% alcohol was tested both by deliberate contamination of rubber catheters and on bronchoscopes after use in patients. The method proved effective in eliminating a wide range of potentially pathogeni...

OBJECTIVES Listeria monocytogenes is a food-borne pathogen that can cause meningitis. The listerial genotype ST6 has been linked to increasing rates of unfavourable outcome over time. We investigated listerial genetic variation and the relation with clinical outcome in meningitis. METHODS We sequenced 96 isolates from adults with listerial meningitis included in two prospective nationwide coh...

PURPOSE Endophthalmitis is a rare complication of intravitreal injection (IVI). It is recommended that povidone-iodine be the last agent applied before IVI. Patients have reported povidone-iodine application to be the most bothersome part of IVIs. Topical anesthetics have been demonstrated to have antibacterial effects. This study compared the minimum inhibitory concentration (MIC) of topical a...

background: the aim of this study was to evaluate and compare the in vitro biofi lm forming capacity of enterococcus faecalis on gutta-percha points disinfected with four disinfectants. materials and methods: a total of 50 gutta-percha points used in this study were divided into four test groups based on disinfectant (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, 20% neem, 13% benzalko...

Benzalkonium chloride (as Roccal or Zephiran) was found to inactivate influenza, measles, canine distemper, rabies, fowl laryngotracheitis, vaccinia, Semliki Forest, feline pneumonitis, meningopneumonitis, and herpes simplex viruses after 10 min of exposure at 30 C or at room temperature. Poliovirus and encephalomyocarditis virus were not inactivated under the same conditions. It was concluded ...

Encephalitis is an acute infl ammation of the meninges and cerebral tissue. Although the specifi c etiological agent is not identifi ed in many instances, clinical and research experience indicate that viruses are the responsible pathogens for most infections. Enteroviruses cause more than 80% of all cases (1, 2). The other frequent viral causes are arboviruses and Herpes viruses. Herpes simple...
