Isolation and identification of pathogenic bacteria. (A) Representative plates from undiluted milk samples from healthy cows. (B) Representative plates from undiluted environmental samples. (C) Representative plates from milk samples (diluted 10 times) with mastitis. (D) Gram-positive irregularity rod-shaped bacteria (scale bar is 10 μm). (E,F) Antimicrobial resistance profiles of the Burkholderia contaminans isolates. The round white papers on the petri dish are antibiotic-sensitive tablets (1: Gentamicin, 2: Ciprofloxacin, 3: Tetracycline, 4: penicillin, 5: lincomycin, 6: Cephalosporin, 7: Streptomycin, 8: Amoxicillin). (G) Phylogenetic analysis of B. contaminans. Red fonts indicate B. contaminans isolates in this study.
