Objective Mutations in 23 S rRNA gene are known to be associated with macrolide resistance in Mycoplasma pneumoniae(M. pneumoniae). However, these mutations alone do not fully explain the high resistance rates in As...
The accelerated weight gain in productive animals as a result of feeding antibiotic enriched fodder has been well known for decades. The better energy harvest is the result of modified gut microbiota as a consequence ...
