Abstract
Ostertagiosis is parasitic disease of cattle that occurs after pathogenic larvae of Ostertagia. ostretagi being swallowed by a cow. The 3th stage larvae of O. ostertagi shed its shell in the rumen and pass into the abomasum, where they inter the gastric glands and molt to fourth stage larvae. During the development of the larvae in the gastric glands parasitized gastric glands have increased in size and have become undifferentiated hyperplastic and dysfunctional. The different cells of this important parts of digestive system of cows especially the damaged gastric acid producing cells are replaced by rapidly multiplying, undifferentiated, immature and non-secreting gastric acid cells which result in major structural, biochemical and physiological changes happens in them. In heavy infection, Sick cows suffer from loss of appetite and diarrhea and lose their body weight. In young cows the rate of growth and weight gain is reduced. The losses are large and compensation, it brings economic inevitability to cattle farms.
