Study on antibiotic resistance of Bifidobacterium breve isolated from maternal and infant feces and breast milk
Bifidobacterium breve is a common type of Bifidobacterium in the human intestine,which has been widely studied for its many beneficial proper-ties.However,there is a serious lack of research on its antibiotic resistance.The study focused on 23 strains of Bifidobacterium breve isolated from maternal and infant feces and breast milk,and tested their resistance to 14 common antibiotics.The study found that the experimental strains were resistant to 12 kinds of antibiotics to varying degrees,only sensitive to ampicillin and linezolid.All experimental strains were resistant to chloramphenicol,ciprofloxacin,kanamycin,tetracycline,gentamicin and neomycin.Further analysis showed that the resistance rate of strains isolated from mother's feces in L family to rifampicin,clindamycin and streptomycin was significantly higher than that of strains isolated from infant's feces and breast milk.The antibiotic resistance phenotype of Bifidobacterium breve varies greatly,even strains isolated from the same family and individual have different antibiotic resistance phenotypes.The study provides basic data for the safety evaluation and application of Bifidobacterium breve.
