چکیده انگلیسی
We have isolated and characterized two distinct types of exfoliative toxin A (ETA)-converting bacteriophages originating from Staphylococcus aureus strains responsible for massive outbreaks of pemphigus neonatorum in the Czech Republic. Three induced phages designated as ÏB531, ÏB557 and ÏB122 were found to be capable of transferring the eta gene into the prophageless non-toxigenic S. aureus strain and converting it into an ETA producer. Comparisons of the phage sequences derived from 12 selected genes and 2 genomic segments (polymorphic P2 and conserved C4) revealed that ÏB531 and ÏB557 were identical each other, but ÏB122 differed from them in 5 gene sequences, the xis gene content and the virion protein profile. Thus, ÏB122 represents a new type of still undescribed ETA-converting phage. This study highlights not only the conclusive genomic diversity of eta gene-positive phages, but also their virulence implications in impetigo S. aureus strains.
