In an attempt to study the composition of the Lactobacillus flora from mucosa of human stomach, 16S rRNA gene sequences of 129 isolates were analysed. For 15 of these, the results differed significantly from known sequences, and additional tests were performed to determine whether these isolates represented as yet unrecognized species. Phenotypic and genetic characteristics revealed that these isolates represented four novel Lactobacillus species. Two belong to the Lactobacillus reuteri and the other two to the Lactobacillus delbrueckii subgroup of Lactobacillus. The names Lactobacillus gastricus sp. nov., Lactobacillus antri sp. nov., Lactobacillus kalixensis sp. nov. and Lactobacillus ultunensis sp. nov. are proposed, with the respective type strains Kx156A7T (=LMG 22113T=DSM 16045T=CCUG 48454T), Kx146A4T (=LMG 22111T=DSM 16041T=CCUG 48456T), Kx127A2T (=LMG 22115T=DSM 16043T=CCUG 48459T) and Kx146C1T (=LMG 22117T=DSM 16047T=CCUG 48460T).
为了研究人类胃黏膜中乳酸杆菌菌群的组成，对129株分离株的16S rRNA基因序列进行了分析。其中15株的结果与已知序列有显著差异，因此进行了额外测试，以确定这些分离株是否代表尚未被识别的物种。表型和遗传特征表明，这些分离株代表了4种新的乳酸杆菌物种。其中两种属于罗伊氏乳杆菌，另外两种属于德氏乳杆菌亚群。建议将其命名为胃乳酸杆菌新种、胃窦乳酸杆菌新种、卡利克斯乳酸杆菌新种和乌尔图纳乳酸杆菌新种，其相应的模式菌株分别为Kx156A7T（=LMG 22113T=DSM 16045T=CCUG 48454T）、Kx146A4T（=LMG 22111T=DSM 16041T=CCUG 48456T）、Kx127A2T（=LMG 22115T=DSM 16043T=CCUG 48459T）和Kx146C1T（=LMG 22117T=DSM 16047T=CCUG 48460T）。
