Three biopsies for realtime
PCR were taken with endoscopic fenestrated alligator
tooth biopsy forceps and snap frozen in liquid nitrogen
and stored at 80C until use, whereas another
four biopsies were fixed in 4% formaldehyde for histological
examination. After recovery from anesthesia, the
foals were returned to their dams. One foal from group
COL died 24 hours after anesthesia because of respiratory
problems.
