A commercial rapid gel immunodiffusion (GID) test was used
for the diagnosis of paratuberculosis (Johne’s disease) in sheep in Saudi
Arabia. The serological results were compared with those obtained by the direct
microscopic examination of Ziehl-Neelsen’s stained fecal smears. The relatively
lower seropositivity rates of the GID than fecal smears in the clinically
suspected groups of animals indicates that the fecal smears are more versatile
than the GID test for the diagnosis of Johne’s disease in sheep.
