Stray dogs may be asymptomatic carriers of Salmonella. We identified 160 Salmonellaisolates, representing 28 different serovars, from stray dogs of central Taiwan. A total of 42 (27%) of the isolates (15 different serovars) were positive for class 1 integrons, with four kinds of gene cassettes. SGI1 were present in 22 of the class 1 integron-positive isolates. This study indicates that widespread occurrence of multidrug resistantSalmonella in stray dogs and the diversity of class 1 integrons and SGI1 in differentSalmonella serovars. Stray dogs may play an important role as carriers of multidrug resistant Salmonella.


Key words: class 1 integrons, Salmonella enterica, stray dogs.
