Simply because no human infection resulting from serotype 1/2 strains has yet been reported in any nation [41], the PCR benefits strongly suggest that all the isolates are serotype two. PFGE analysis identified four associated patterns, A1 four (Table 1 and Supplementary Fig. 1). The predominant pattern, A1, was characteristic of 18 isolates. Sequencing in the TR9 locus from the MLVA scheme revealed 17 variants, with 8?2 repeats. Virulence phenotypes and determinants Ten isolates (48 ) have been capable to form biofilm within the medium supplemented with fibrinogen (Table 1); no biofilm was observed in the absence of this title= jir.2014.0149 compound. Fifteen isolates (71 ) showed variable levels of DNase activity. Having a single exception, all isolates caused different degrees of -L bounds on calibration constraints. This result likely applies to Bayesian haemolysis of horse blood and harboured the sly gene.
