Too members on this forum have had correspondence with Dr. Jacobson (and shared the same on this forum) directly and have read enough literature on IBD to know that the leading researchers on this disease state that snakes can be asymptomatic carriers for an indefinite period of time. The members of this forum are pretty well boned up on IBD - please don't confuse people new to hobby by making them think that IBD and OPMV always strike fast and kill fast. It is simply and blatantly false......and it adds to the misinformation that surrounds these diseases.
OPMV has similar characteristics. Despite what the BBC gloss piece states, it is commonly known in this hobby that animals exposed to OPMV can be considered asymptomatic carriers for up to 24 months.
