Rhinoviruses: kinetics of ultraviolet inactivation and effects of UV and heat on immunogenicity. 1979

J H Hughes, and M Mitchell, and V V Hamparian

The kinetics of ultraviolet inactivation for two human rhinoviruses and poliovirus were compared. No major differences in the rates of ultraviolet inactivation were detectable. All viral preparations inactivated by ultraviolet irradiation induced neutralizing antibody in guinea pigs. In contrast, when guinea pigs were immunized with a heat inactivated rhinovirus preparation, little or no neutralizing antibody was elicited. Immune electron microscopy of the heated rhinovirus preparations revealed the presence of particles resembling empty capsids. These results suggest that rhinoviruses and enteroviruses are affected in a similar manner when subjected to ultraviolet or heat inactivation.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D009500 Neutralization Tests The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).

D012229 Rhinovirus A genus of PICORNAVIRIDAE inhabiting primarily the respiratory tract of mammalian hosts. It includes over 100 human serotypes associated with the COMMON COLD. Common Cold Virus,Coryza Viruses,Cold Virus, Common,Cold Viruses, Common,Common Cold Viruses,Coryza Virus,Rhinoviruses
D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.

D017955 Poliovirus A species of ENTEROVIRUS which is the causal agent of POLIOMYELITIS in humans. Three serotypes (strains) exist. Transmission is by the fecal-oral route, pharyngeal secretions, or mechanical vector (flies). Vaccines with both inactivated and live attenuated virus have proven effective in immunizing against the infection.
