Supernatant fluid from liquid medium
cultures of phase I Bordetella pertussis
organisms (pertussis supernatant) when
given to calves and sheep by intravenous
injection produces a marked lymphocytosis. Thoracic duct and splenic vein
cannulation was performed in some animals to study the mechanism of production of this lymphocytosis. There was a
transient increased mobilization of lymphocytes from the lymphoid organs as
seen by the increase in output of lymphocytes from thoracic duct and splenic vein
within a few minutes following administration of pertussis supernatant. This
was followed by a decrease in the
thoracic duct cell output as long as the
blood lymphocyte count remained elevated, indicating an inhibition of recirculation of lymphocytes from blood to
lymph. There was no evidence of increased new cell production.
