The horses were in two stables: in the first stable they were kept together with sheep and in the second stable they were kept together with goats. All horses in both stables were diagnosed as being infested with the cat flea Ctenocephalides felis felis. Foals were severely infested, whereas adult horses were only moderately infested.
