Characterization of feline-originated probiotics Lactobacillus rhamnosus CACC612 and Bifidobacterium animalis subsp. lactis CACC789 and evaluation of their host response

Table 5 Antibiotic resistance of feline-originated probiotics

Strain	Minimal inhibition concentration (MIC, µg/mL)
Strain	Ampicillin	Vancomycin	Gentamicin	Kanamycin	Erythromycin	Clindamycin	Tetracycline
CACC612	2	> 256^R	48	> 256^R	1	0.094	8
CACC789	0.064	0.75	192	> 256^R	0.047	< 0.016^S	8
EFSA guideline for Lactobacillus rhamnosus	4	n.r.	16	64	1	1	8
EFSA guideline for Bifidobacterium	2	2	64	n.r.	1	1	8

Quantitative antibiotic sensitivity is expressed as the minimum inhibitory concentration against the microbial strains and classified as R, resistant (≥ 32 or 256 µg/ml), S, sensitive (< 0.016 µg/ml), and n.r., not required in European food safety authority (EFSA)
