Using a modified cold enrichment procedure Yersinia spp. were detected in 90.6% out of 32 raw waste water samples obtained within one year from two municipal sewage treatment plants. Moreover Yersinia were isolated from 50% of 6 effluent samples. Altogether 118 Yersinia strains were isolated and typed biochemically and serologically. 69 out of these isolates belonged to Yersinia enterocolitica, 60 strains to biotype 1, and 9 to biotype 4, serotype 0:3, 8 strains Yersinia enterocolitica serotype 0:3, biotype 4, considered to be a causative agent in human enteritis, harboured an 48 MD plasmid. The remaining isolates were identified as Yersinia frederiksenii (24 strains), Yersinia intermedia (22 strains) and Yersinia kristensenii (3 strains). The frequency of the isolation of Y. enterocolitica serotype 0:3, biotype 4 from sewage showed the same seasonal dependence as known from strains of human origin. In contrast to this, such dependence could not be found among other serovars of Y. enterocolitica and related species.

UI	MeSH Term	Description	Entries
D010957	Plasmids	Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS.	Episomes,Episome,Plasmid
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D004269	DNA, Bacterial	Deoxyribonucleic acid that makes up the genetic material of bacteria.	Bacterial DNA
