Possible illness in boa

[Vypyrz]

My female boa aged 8 has stopped feeding for the last 4 mths. I had a similar problem 4 years ago with another boa,who stopped feeding but looked bloated(i assumed wrongly she was gravid),6 mnths later she died after a bloody mucus was produced from her rear. My vet told me it was probably a stomach illness which is common in boas. My problem lies in i have since moved to greece with all my herps and finding a knowledgeable vet is impossible. She lives in a viv with another boa and a burmese python who as yet have no problems (touch wood). Does anyone have any idea what this could be and how to treat it,i can get antibiotics but dont know if this will help or hinder. THANKYOU

How long has she lived with the other boa and Burm and what size enclosure are they living in? Is she showing any symptoms other than not eating.
My first guess, without any details is that they all need to be separated. If that boa has gotten a disease or something, it will spread quickly. She may not be eating because of stress...
