The total and differential leukocyte counts of 238 infants with acute gastroenteritis were evaluated as an aid in differentiating between nonbacterial and bacterial infection. In contrast to the total leukocyte count, which was noncontributory, the absolute band count and the ratio between band and total neutrophil count (B/N ratio) were helpful, with the highest values seen in patients with Shigellosis. A B/N ratio greater than 0.10 can help differentiate Shigella, Salmonella, and Campylobacter infections from E. coli and nonbacterial gastroenteritis with a sensitivity of 84.3 per cent and a specificity of 74.5 per cent.
对238例急性胃肠炎婴儿的白细胞总数及分类计数进行评估，以辅助鉴别非细菌性感染和细菌性感染。与无诊断价值的白细胞总数不同，绝对杆状核细胞计数以及杆状核细胞与中性粒细胞总数之比（B/N比）具有诊断价值，其中志贺菌病患者的这些指标值最高。B/N比大于0.10有助于鉴别志贺菌、沙门菌和弯曲杆菌感染与大肠杆菌感染及非细菌性胃肠炎，其敏感性为84.3%，特异性为74.5%。
