Aarestrup (2000) reported that resistance to streptothricin antibiotics has been described in Gram-negative bacteria as a result of using nourseothricin as an antimicrobial feed promoter in industrial animal farms in Germany.
This cassette contains the aadAl, sat2, and dfrAl genes that confer resistance to aminoglycosides, streptothricin, and trimethoprim and was chromosomally integrated adjacent to the glmS gene in these isolates (indicating a single acquisition event).
The normally harmless bacteria, which serve as an indicator of fecal contamination, were resistant to five common antibiotics: chloramphenicol, erythromycin, streptornycin, streptothricin, and kanamycin.
