Intestinal cryptosporidiosis and reovirus isolation from bobwhite quail (Colinus virginianus) with enteritis

An acute enteric disease of young pen-raised bobwhite quails was studied. Affected quails had white, watery diarrhea accompanied by dehydration and subsequent death. Mortality from hatch to 17 days of age ranged from 30 to 45% in the three flocks examined. Small intestines were thin-walled and diste...

Zusammenfassung:An acute enteric disease of young pen-raised bobwhite quails was studied. Affected quails had white, watery diarrhea accompanied by dehydration and subsequent death. Mortality from hatch to 17 days of age ranged from 30 to 45% in the three flocks examined. Small intestines were thin-walled and distended with fluid and gas. Microscopic lesions in the intestinal tract consisted of villus atrophy, villus fusion, and sloughing of cells at the tip of the villi in duodenum, jejunum, and ileum. Cryptosporidium sp. and reovirus were identified in affected quails. /// Se estudió una enfermedad entérica aguda de codornices jóvenes. Las codornices afectadas presentaban diarrea acuosa y blanquecina seguida por deshidratación y muerte. La mortalidad hasta los 17 días de edad fluctuó del 30 al 45% en los tres lotes examinados. El intestino delgado presentaba una pared delgada y distendida con fluido acuoso y presencia de gas. Las lesiones microscópicas en el tracto intestinal consistieron de atrofia y fusión de las vellosidades con desprendimiento de las células del extremo de las vellosidades del duodeno, yeyuno e íleon. En las codornices afectadas se identificó Cryptosporidium sp. y reovirus.
