ABSTRACT
Two P. mirabilis strains, PmSHR21 and PmSHR38, were collected from chicken flocks in Sharkia Governorate, Egypt in 2016. The two strains showed multidrug-resistance (MDR) phenotypes and were detected to harbour I) floR and sul1 genes conferring resistance to florfenicol and chloramphenicol, and sulfonamides, respectively, II) a ~1.9â¯kbp class 1 integron containing aadA2-lnuF genes conferring resistance to spectinomycin and streptomycin, and lincosamides, respectively. Interestingly, the two strains were detected to contain SGI1 variant, SGI1-W and inserted between the 3' end of the chromosomal trmE gene and the hipB/hipA toxin/antitoxin homologue. Fingerprinting by ERIC-PCR of the two poultry strains identified in this study and the two human SGI1-carrying P. mirabilis strains described recently in our study showed identical ERIC-pattern between SGI1-W-carrying poultry and human strains, suggesting that they might be clonally related. The detection of SGI1 and its variants in P. mirabilis isolated from humans and chicken flocks in Egypt clarify the geographical and biological spreading through an inter-transmission pathway. To the best of our knowledge, this is the first study detecting SGI1-positive P. mirabilis isolated from chicken flocks in Africa.
