Antimicrobial resistance patterns (ARP), virulence profiles and plasmids in clinical isolates of Yersinia enterocolitica serotype O:3 were studied. The ARP was tested using the disk method. All strains were susceptible to amoxicillin/clavulanic acid, cefoxitin, fosfomycin, gentamicin, kanamycin, neomycin, tetracycline, nalidixic acid, norfloxacin, ciprofloxacin and trimethoprim. All of them presented resistance to ampicillin, all with the exception of one to cephalotin, differing in resistance or susceptibility to chloramphenicol, streptomycin (Sm), sulfadiazine (Sd) and cotrimoxazole. Due to these differences they were grouped into 8 ARP. Twenty-nine strains carried plasmids and were grouped into 5 plasmid profiles. All strains carrying 42 MDa plasmids were positive for virulence tests (calcium dependence, crystal violet binding, Congo red binding and autoagglutination). No correlation between ARP and plasmid profile was found, although small plasmids of 6.5 and 4.1 MDa mediated resistance to Sm-Sd, as was shown by transformation to Escherichia coli strains. DNAs from plasmids were analyzed by restriction enzymes. All 42 MDa plasmids showed identical EcoRI and HindIII profiles. The two 6.5 MDa plasmids showed identical BglII, AvaI and SalI restriction profiles and the four 4.1 Mda plasmids also yielded restriction profiles similar to each other, but different from the 6.5 ones.

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
D012150	Polymorphism, Restriction Fragment Length	Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment.	RFLP,Restriction Fragment Length Polymorphism,RFLPs,Restriction Fragment Length Polymorphisms
D003227	Conjugation, Genetic	A parasexual process in BACTERIA; ALGAE; FUNGI; and ciliate EUKARYOTA for achieving exchange of chromosome material during fusion of two cells. In bacteria, this is a uni-directional transfer of genetic material; in protozoa it is a bi-directional exchange. In algae and fungi, it is a form of sexual reproduction, with the union of male and female gametes.	Bacterial Conjugation,Conjugation, Bacterial,Genetic Conjugation
D004352	Drug Resistance, Microbial	The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).
