摘要：
The effect of Brucella on the generation of microbicidal reactive oxygen and nitrogen metabolites by bovine peripheral polymorphonuclear cells (PMNs) was investigated. The PMNs were recovered from the peripheral blood of control calves and experimental calves previously vaccinated against brucellosis. Significantly larger quantities of NO and H2O2 were generated by PMNs from control and experimental calves following activation by heat-killed whole cells or outer membrane protein of Brucella abortus than by non-activated cells (p<0.05–0.01). In contrast, generation of H2O2 and NO decreased when PMNs were exposed to the lipopolysaccharide of Brucella. However, the generation of H2O2 and NO by activated PMNs from the control and experimental calves did not differ significantly.
