The effect of sanfetrinem, a member of a new class of antibiotics, upon the
in-vitro interaction between human polymorphonuclear granulocytes (PMNs)
and a multiply resistant strain of Klebsiella pneumoniae was investigated.
Sub-MICs of sanfetrinem significantly enhanced PMN phagocytosis and greatly
reduced the survival of intracellular bacteria compared with
antibiotic-free systems. The distinction between any effect of sanfetrinem
on the klebsiellae and the phagocytes was made by exposing each of them to
the drug before they were incubated together. The results indicate that
sanfetrinem may have a direct positive action either on K. pneumoniae or on
human granulocytes.
