The issue of what in fact constitutes politeness remains a source of considerable debate amongst researchers. There is mounting evidence that although there may be common underlying elements, politeness is conceptualised differently across cultures. A comparison of the notions of politeness in English and teinei, reigi tadashii and keii hyoogen in Japanese indicates that these respective terms encompass somewhat different conceptual ranges. Politeness in English refers to showing consideration for others and demonstrating a polished self-presentation. In Japanese, on the other hand, it encompasses showing respect (with a strong nuance of vertical respect involved) and consideration towards the position and quality of character of others, and modesty about oneself While politeness in both English and Japanese involves showing one thinks well of others (other-oriented politeness) and showing one does not think too highly of oneself (self-oriented politeness), differences in the underlying conceptualisation of politeness give rise to different ways of expressing politeness. It is thus difficult to maintain the assumption that politeness can be defined in the same way across different cultures, although this does not necessarily preclude the identification of common elements of politeness across cultures. © Walter de Gruyter.

Objectives: To determine clonality and identify plasmid-mediated resistance genes in 11 multidrug-resistant Escherichia coli (MDREC) isolates associated with opportunistic infections in hospitalized dogs in Australia. Methods: Phenotypic (MIC determinations, modified double-disc diffusion and isoelectric focusing) and genotypic methods (PFGE, plasmid analysis, PCR, sequencing, Southern hybridization, bacterial conjugation and transformation) were used to characterize, investigate the genetic relatedness of, and identify selected plasmid-mediated antimicrobial resistance genes, in the canine MDREC. Results: Canine MDRECs were divided into two clonal groups (CG 1 and 2) with distinct restriction endonuclease digestion and plasmid profiles. All isolates possessed bla(CMY-7) on an similar to 93 kb plasmid. In CG 1 isolates, bla(TEM), catA1 and class 1 integron-associated dfrA17-aadA5 genes were located on an similar to 170 kb plasmid. In CG 2 isolates, a second similar to 93 kb plasmid contained bla(TEM) and unidentified class 1 integron genes, although a single CG 2 strain carried dfrA5. Antimicrobial susceptibility profiling of E. coli K12 transformed with CG 2 large plasmids confirmed that the bla(CMY-7)-carrying plasmid did not carry any other antimicrobial resistance genes, whereas the bla(TEM)/class 1 integron-carrying plasmid carried genes conferring resistance to tetracycline and streptomycin also. Conclusions: This is the first report on the detection of plasmid-mediated bla(CMY-7) in animal isolates in Australia. MDREC isolated from extraintestinal infections in dogs may be an important reservoir of plasmid-mediated resistance genes.
