[Plasmid composition of Yersinia pestis strains from different natural foci]. 1992

A A Filippov, and N S Solodovnikov, and L M Kukleva, and O A Protsenko

The study of the plasmid composition of 246 Y. pestis strains from different natural foci in the USSR and other countries revealed that 173 strains (70%) carried three known plasmids with a molecular weight of about 6, 45-50 and 60 megadaltons (MD) respectively. In 20 strains (8%) obtained from different sources additional cryptic plasmids were detected. In some cases the absence of one or two typical plasmids was observed. Replicon pPst was shown to have quite constant molecular weight (6 MD), whereas plasmids pCad and especially pFra exhibited certain variations of their molecular weight (45-49 MD and 60-149 MD respectively) in strains of different origin.

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
D004197	Disease Reservoirs	Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks. Humans may serve both as disease reservoirs and carriers.

D004587	Electrophoresis, Agar Gel	Electrophoresis in which agar or agarose gel is used as the diffusion medium.	Electrophoresis, Agarose Gel,Agar Gel Electrophoresis,Agarose Gel Electrophoresis,Gel Electrophoresis, Agar,Gel Electrophoresis, Agarose
D005798	Genes, Bacterial	The functional hereditary units of BACTERIA.	Bacterial Gene,Bacterial Genes,Gene, Bacterial
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
