mycoplasma isn't a bacteria (it's a plasma), and some other respiratory infections are viruses, neither of which are touched by antibiotics, so giving them in such cases just encourages the development of antibiotic resistance in bugs that are exposed to them.These people say chickens who sneeze don’t have cold like humans. It’s always a bacteria who causes it. The Dutch name for it is snot. Google doesn’t translate snot. Maybe its a chicken word for all sneezing diseases like Mycoplasma and Coryza.![]()
