title: Blood culture of the canine patient.
abstract: Blood for bacteriologic culture was obtained from 581 sick dogs. Of these, 134 (23%) were considered to have bacteremia. The conditions most frequently associated with bacteremia were malignant neoplasms and infections of the skeletal, cardiovascular, and urogenital systems. The most frequently isolated bacteria were members of the family Enterobacteriaceae and coagulase-positive staphylococci, in sum accounting for more than 50% of the 150 isolates. Most of the dogs with bacteremia had high proportions of immature neutrophils, segmented neutrophils, and monocytes in blood. Dogs with bacteremia and osteomyelitis due to staphylococci had normal hemograms. Blood from dogs with bacteremia due to gram-negative bacteria was more likely to have a high proportion of immature and segmented neutrophil leukocytes than was blood from dogs with bacteremia due to a gram-positive species. Toxic neutrophils were observed more often in blood obtained from patients with bacteremia due to gram-negative bacteria. The development of fever correlated with the bacteremic state regardless of the species of bacteria in the blood.
