Hygromycin B, is an antibiotic produced by the bacterium Streptomyces hygroscopicus. It is an aminoglycoside that kills bacteria, fungi and higher eukaryotic cells by inhibiting protein synthesis[1].


Hygromycin B was originally developed in the 1950's for use with animals and is still added into swine and chicken feed as an anthelmintic or anti-worming agent (product name: Hygromix). Hygromycin B is produced by Streptomyces hygroscopicus, a bacterium isolated in 1953 from a soil sample. Resistance genes were discovered in the early 1980's.[2][3]

Use in research

In the laboratory it is used for the selection and maintenance of prokaryotic and eukaryotic cells that contain the hygromycin resistance gene. The resistance gene is a kinase that inactivates hygromycin B through phosphorylation.[4] Since the discovery of hygromycin-resistance genes, hygromycin B has become a standard selection antibiotic in gene transfer experiments in many prokaryotic and eukaryotic cells.
