Correlation of Serological and Biochemical Groupings of Yersinia enterocolitica with the β-Lactamases of the Strains Matthew, Margaret and Cornelis, G. and Wauters, G.,, 102, 55-59 (1977), doi = https://doi.org/10.1099/00221287-102-1-55, publicationName = Microbiology Society, issn = 1350-0872, abstract= The β-lactamase isoelectric focusing patterns of 37 strains of Yersinia enterocolitica from various serological and biochemical groups were examined. Strains of different serological groups generally had different patterns, but those of serological groups 1, 2, 3 and 9 were identical., language=, type=
