Detailed information regarding the kinetics of thermal inactivation of Pichinde, an arenavirus, is presented. Inactivation of virus infectivity proceeded as a first order reaction over the temperature range 22-53 degrees C. The determined inactivation rates analysed as a function of absolute temperature revealed that two different reactions were involved. Below 37 degrees C, the energy of activation was determined to be compatible with RNA degradation, whereas at higher temperatures a correspondingly greater value suggests that protein inactivation contributes significantly to loss of infectivity. Both inactivation reactions were retarded in the presence of foetal calf serum to a final concentration of 1%. The relatively short half-life of 12-24 h at 22 degrees C suggests transmission in nature via contaminated foodstuffs and soil may be inefficient.
