Abstract

A molecular epidemiology study was carried out on Salmonella mbandaka and Salmonella corvallis strains identified from two food-poisoning outbreaks which occurred in August 1985 in Pistoia and in October 1985 in Sant'Ilario d'Enza (RE). All the Salmonella mbandaka strains were plasmid-free; all the epidemic Salmonella corvallis strains, in contrast to the non epidemic isolates, carried a small plasmid of approximately 2 MDa molecular weight. Restriction enzyme cleavage pattern analysis revealed that the plasmids of the epidemic strains were closely related.

Abstract

A molecular epidemiological study was carried out on 60 Salmonella dublin isolates identified at the Southern Italy Enterobacteriaceae Center between 1971 and 1985. These included 23 isolates from children with diarrhoea in Palermo obtained during 1984. All isolates from the outbreak of gastroenteritis in children were resistant to chloramphenicol and streptomycin and harboured two plasmids of 50 MDa and 3 MDa molecular weight, whereas the majority of the isolates identified before 1984 were susceptible to these antibiotics and carried only a 50 MDa molecular weight plasmid. Four S. dublin strains successively identified from cattle (Palermo, Foggia, Portici) and from a child (Palermo) were shown to possess similar antibiotic resistance patterns and plasmid profiles to S. dublin isolates from the outbreak of gastroenteritis in children. The 50 MDa plasmid was shown to be associated with virulence in mice, while it was not possible to assign any genetic function to the 3 MDa plasmid.

4. [Resistance to antibiotics and resistance factors in Salmonella wien strains isolated in Sicily]

Abstract

The majority of the strains of S. wien isolated in Sicily were resistant to six different antibiotics, showing the same resistance pattern (ASKCTSu) observed in strains isolated in other provinces of Italy. After conjugation with E. coli K12, the transfer of the whole pattern or of various groups of resistances was observed, which suggests the presence of several co-existent R plasmids. The results obtained suggest that the various outbreaks occurred in Italy have the same origin. They can be correlated with the epidemic of S. wien with the same transferable pattern of antibiotic resistance, spread in France in recent years from Algiers.
