Prevalence, species distribution and antimicrobial resistance of enterococci isolated from dogs and cats in the United States.

摘要: Aims:  The contribution of dogs and cats as reservoirs antimicrobial resistant enterococci remains largely undefined. This is increasingly important considering the possibility transfer bacteria from companion animals to human host. In this study, veterinary clinics were screened for presence enterococci. Methods Results:  A total 420 isolated nasal, teeth, rectal, belly hindquarters sites 155 121 three in Athens, GA. Eighty per cent (124 out 155) 60% (72 121) positive enterococci. From number dog samples (n = 275), 32% (n = 87) hindquarter, 31% (n = 86) 29% (n = 79) area. majority isolates originated rectal (53 145; 37%) cats. predominant species identified was Enterococcus faecalis (105 155; 68%) E. hirae (63 121; 52%) Significantly more than any other enterococcal (P < 0·05) both suggesting site specific colonization species. highest levels resistance ciprofloxacin faecium (9 10; 90%), chloramphenicol (17 20; 85%) gentamicin (19 24; 79%) nitrofurantoin (15 19; Multi-drug (MDR) (resistance ≥2 antimicrobials) observed few two many eight antimicrobials regardless class. Conclusion:  study demonstrated that are commonly colonized with enterococci. Significance Impact Study:  Dogs may act genes can be transferred pets people.
