The emergence of waterborne viruses with resistance to disinfection has been demonstrated in the laboratory and in the environment. Yet, the implications of such resistance for virus control remain obscure. In this study we investigate if viruses with resistance to a given disinfection method exhibit cross-resistance to other disinfectants. Chlorine dioxide (ClO2)- or UV-resistant populations o...
The interaction between echovirus 11 strain 207 (EV11-207) and decay-accelerating factor (DAF or CD55) at the apical surface of polarized Caco-2 cells results in rapid transport of the virus to tight junctions and in its subsequent uptake. A virus mutant (EV11-207R) which differs at 6 amino acids and whose affinity for DAF is apparently significantly lower remains at the apical surface, from wh...
Laboratory strains of enteroviruses, as well as viruses isolated from raw wastewater, were found to exhibit enhanced infectivity in vitro when BGM cell monolayers were pretreated with the cationic polymer polyethyleneimine (PEI). Viruses were assayed by the cytopathic effect technique and as PFU under methylcellulose and agar overlays with monolayers treated with 0 to 5.0 x 10(-3)% (wt/vol) PEI...
A total of 38 adult cases of aseptic meningitis were diagnosed based on clinical manifestations as well as examination of cerebrospinal fluid at Kaohsiung Veterans General Hospital in 2001. The majority (31 cases, 82%) of cases occurred between June and August, and most (33 cases, 87%) of them aged from 18 to 35 years (median age, 25 years). The male-to-female ratio was 2.16:1. Common clinical ...
Hand, foot and mouth disease (HFMD) is a contagious enteroviral infection occurring primarily in children and characterized by vesicular palmoplantar eruptions and erosive stomatitis. Echovirus 4 (EV-4) has been commonly associated with aseptic meningitis. The association of HFMD with EV-4 has not been reported previously. Two samples of a 14-month child who presented mild fever, sores in the m...
