The experiments with the collection of strains and diagnostic sera available in the USSR confirmed the data contained in the literature on the good prospects of using the indirect hemagglutination test for the serotyping of bacteria belonging to the genus Providencia. Certain differences were observed in cross reactions, revealed by the indirect hemagglutination test and by agglutination: the interrelations of serogroups O14 and O25, O23 and O25, O23 and O29, O29 and O45, O37 and O49, determined by means of the indirect hemagglutination test, could not be detected in the same sera by the slide and tube agglutination tests. For the first time the usefulness of aqueous-saline extracts of agar cultures in the indirect hemagglutination inhibition test to specify more precisely the interrelations between individual bacterial serogroups of the genus Providencia has been shown.
在苏联利用现有菌株和诊断血清所做的实验证实了文献中关于使用间接血凝试验对普罗威登斯菌属细菌进行血清分型具有良好前景的数据。间接血凝试验和凝集反应所揭示的交叉反应存在某些差异：通过间接血凝试验确定的血清群O14与O25、O23与O25、O23与O29、O29与O45、O37与O49之间的相互关系，用玻片和试管凝集试验在相同血清中无法检测到。首次证明了琼脂培养物的盐水提取物在间接血凝抑制试验中有助于更精确地确定普罗威登斯菌属各细菌血清群之间的相互关系。
