A study was made of morphological, cultural, biochemical properties and antigenic structure (by O-antigen) of 59 strains isolated in group acute intestinal affection of children at the pioneer camp. By the combination of biochemical properties (31 tests) all the cultures isolated were referred to Providencia alcalifaciens of biotype 7. Serological typing with the aid of experimental diagnostic agglutinating O-sera showed these strains to be referred to serological group O2. Identity of the O-antigen of the isolated cultures to the standard O2 strain was confirmed by the results of cross reactions of agglutinin absorption. The results of bacteriological and clinico-epidemiological studies offered a possibility of regarding the isolated Providencia alcalifaciens of serological group O2 as the causative agents of the group intestinal disease in children.
对在少年先锋营儿童群体急性肠道疾病中分离出的59株菌株进行了形态学、培养特性、生化特性及抗原结构（O抗原）的研究。根据生化特性组合（31项检测），所有分离培养物均归为生物型7的产碱普罗威登斯菌。借助实验诊断性凝集O血清进行血清学分型，结果显示这些菌株属于血清群O2。凝集素吸收交叉反应结果证实，分离培养物的O抗原与标准O2菌株的O抗原一致。细菌学及临床流行病学研究结果表明，血清群O2的产碱普罗威登斯菌可能是儿童群体肠道疾病的病原体。
