Summary
WEHI mice infected with LCM virus or with the virulent Hampstead mouse strain of ectromelia virus showed a decrease in the output of small lymphocytes from the thoracic duct. These infections were lethal, and caused thymic cortex depletion and fatty liver changes which were especially severe in the case of LCM virus infection. These changes were due to an adrenal-cortex mediated response. The fall in cell output from thoracic lymph could be attributed to the combined effects of the destruction of infected splenic and lymph node lymphocytes, and lymphocyte-destruction mediated by the corticosteroid stress response to infection.
In C57BL mice infected with LCM virus and in WEHI mice infected with the avirulent Hampstead egg strain of ectromelia virus there was no change in small lymphocyte output. These infections were non lethal, with no sickness, minimal stress changes, and little or no destruction of lymphocytes.
