title: The effects of fimbriate and non-fimbriate strains of Escherichia coli on the oxidative reactions of neutrophils from a variety of species.
abstract: 5 fimbriate strains and 5 non-fimbriate strains of Escherichia coli were tested for their ability to enhance the cyanide insensitive oxygen consumption of human, bovine and ovine blood neutrophils in the absence of serum opsonins. Neutrophils from all 3 animal species showed significantly increased oxygen consumption when challenged with fimbriate strains. Only ovine neutrophils were stimulated by non-fimbriate strains although to a lesser extent than by fimbriate strains. In the presence of serum the stimulation of ovine neutrophils was the same whether fimbriate or non-fimbriate strains were used.
