Whole-hands and fingerpads of seven volunteers were contaminated with poliovirus type 1 Sabin strain in order to evaluate virucidal efficacy of different forms of handwashing and handrub with alcohols and alcohol-based disinfectants. In the whole-hand protocol, handwashing with unmedicated soap for 5 min and handrubbing with 80% ethanol yielded a log(More)
OBJECTIVE With changed consumer behaviour in the drug scene the psychiatric complications with the derivates of amphetamine increase. In some regions methamphetamin is particularly common.

518 stool specimens from patients with acute gastroenteritis, presumed to suffer from infections with enteropathogenic E. coli, were screened for rotavirus. Rotaviruses were found in 23.3%. Specimens containing virus mainly belonged to hospitalised infants aged less than 6 months. In 4 cases enteropathogenic E. coli were found in addition to rotaviruses.(More)
During a period of 3 weeks, 17 premature neonates 4 of them weighing less than 1000 g at birth became infected with echovirus 11 in a neonatal intensive-care unit. Beside 3 inapparent infections, severe 'septicaemic' illness was observed among 5 premature neonates combined with meningitis and apnoeic attacks. 4 neonates presented meningitis as the(More)
Among 7 inorganic per-compounds tested potassium permanganate as 1% solution showed the greatest virucidal efficacy against poliovirus type I and reached a reduction rate of 4.1 after 30 sec exposure time. Potassium peroxomonosulfate produced a reduction rate of 5.6 after 5 min, whereas perchloric acid and sodium perborate needed 15 min and hydrogen(More)
518 fecal specimens were examined by SDS-PAGE after rotavirus had been detected by an ELISA. The material was collected from 239 patients in three children's hospitals in Bremen over a period of one year. Seventy-two percent of the children had a nosocomial infection. Eight electropherotypes could be distinguished by electrophoresis, one of which (type C)(More)
