what medicine?

[Skiploder]

my vet had told me that the result proved that it is a kind of FAKE Staphylococcus aureus which look alike but actually it's not Staphylococcus aureus, i'll try getting the name of the medicine later on

the culture is testing for both bateria and virus, only FAKE Staphylococcus aureus react with it

what are the symtoms of IBD??

IBD symptoms can be major to minor. They can present as neurological or they can present as a myriad of sub clinical infections that arise from the compromising of the animal's immune system. These can range to chronic respiratory infections, etc.

You lost a number of other animals to this disease - did you have any necropsies done?

Therefore there are no definitive symptoms.
