Welcome to BYC. Wheezing can be one of the signs of a respiratory disease, such as MG, coryza, ILT, aspergillosis, and others. Some are caused by viruses, bacteria, mycoplasma, and fungus. It would be good to know what she has by comparing her symptoms, and getting her tested. Antibiotics such as Tylan, oxytetracycline, Gallimycin, and sulfa drugs are just some of the medicines commonly used to treat the bacterial or mycoplasmal diseases. Viruses have to run their course, but secondary infections can be common.
