dc.description.abstractPOWDERED INFANT FORMULAS (PIF) ARE THE MOST USED DIETARY SUBSTITUTES THAT ARE USED IN ORDER TO SUPPLEMENT BREASTFEEDING. HOWEVER, PIF ARE NOT STERILE AND CAN BE CONTAMINATED WITH DIFFERENT MICROORGANISMS. THE OBJECTIVE OF THIS STUDY WAS TO GENOMICALLY CHARACTERIZE ENTEROBACTERIACEAE (ENT) AND ENTEROCOCCUS STRAINS THAT WERE ISOLATED FROM PIF. STRAINS WERE IDENTIFIED BY MATRIX-ASSISTED LASER DESORPTION IONIZATION?TIME-OF-FLIGHT MASS SPECTROMETRY (MALDI-TOF MS) AND WHOLE GENOME SEQUENCING (WGS). GENOMIC TYPING, DETECTION OF VIRULENCE, AND RESISTANCE PROFILES AND GENES WERE PERFORMED WITH THE RIDOM SEQSPHERE+ SOFTWARE; THE COMPREHENSIVE ANTIBIOTIC RESISTANCE DATABASE (CARD) PLATFORM; RESFINDER AND PLASMIDFINDER TOOLS; AND BY THE DISK DIFFUSION METHOD. NINETEEN ISOLATES FROM PIF WERE ANALYZED, INCLUDING ENT SUCH AS KOSAKONIA COWANII, ENTEROBACTER HORMAECHEI, FRANCONIBACTER HELVETICUS, MIXTA CALIDA, AND LACTIC ACID BACTERIA SUCH AS ENTEROCOCCUS FAECIUM. THE STRAINS EXHIBITED RESISTANCE TO BETA-LACTAMS, CEPHALOSPORINS, AND MACROLIDES. RESISTANCE GENES SUCH AS ACRAB-TOLC, MARA, MSBA, KNPEF, OQXAB, FOSA, BLAACT-7, BLAACT-14, QACJ, OQXAB, AAC(6?)-II, AND MSR(C); AND VIRULENCE GENES SUCH AS ASTA, CHEB, CHER, OMPA OMPX, TERC, IRONA, ACM, AND EFAAFM, ADEM WERE ALSO DETECTED. ALL THE ANALYZED STRAINS POSSESSED GENES THAT PRODUCED HEAT-SHOCK PROTEINS, SUCH AS IBPA AND CLPL. IN PIF, THE PRESENCE OF ENT AND ENTEROCOCCUS THAT ARE MULTIRESISTANT TO ANTIBIOTICS TOGETHER WITH RESISTANCE AND VIRULENCE GENES POSE A HEALTH RISK FOR INFANTS CONSUM- ING THESE FOOD PRODUCTS.
