Human and animal enteric caliciviruses in oysters from different coastal regions of the United States

Article Abstract:

A survey of regional markets was conducted to determine the occurrence of human and animal enteric caliciviruses in United States market oysters. The data results indicate that the presence of animal enteric caliciviruses was associated with states with high livestock production and although the presence of human caliciviruses in raw oysters represents a potential risk for gastroenteritis, disease confirmation by investigation of outbreaks is required.

Inactivation of caliciviruses

Article Abstract:

The inactivation of the two animal caliciviruses enteric canine calicivirus no.48 (CaCV) and the respiratory feline calicivirus F9 (FeCV) were studied to increase the insight into transmission routes and methods available to inactivate human enteric noroviruses. FeCV is preferred for the human enteric noroviruses over the use of CaCV due to the greater convenience of FeCV in the laboratory and greater stability at low pH.

Calicivirus inactivation by nonionizing (253.7-nanometer-wavelength [UV}) and ionizing (gamma) radiation

Article Abstract:

The inactivation of two cultivatable animal calciviruses, feline calcivirus (FeCV) strain F9 and canine calcivirus (CaCV) strain number 48, which have highly divergent capsid sequences, are determined and the results are compared with inactivation of bacteriophage MS2. The calciviruses are used to study inactivation by nonionizing (253.7-nanometer-wavelength [UV]) and ionizing (gamma) radiation.
