Bacteriophages are frequently used in air experiments as suitable surrogates for human and animal viruses^([1]). Bacteriophages are non-pathogenic, so they are safe for laboratory workers and do not require specialized biological protection measures.Bacteriophages can be prepared at high titers using simple and low-cost methods.展开更多
