Sanitation of Feedlot Soil
The topic is the sanitation of feedlot soil due to the presence of coliform bacteria from feces and naturally occurring in the soil. This bacteria can caused diarrhea in lambs, calves and piglets. This article reviews a study on this topic that was conducted in the Fall of 1979 at NDSU in the Departments of Veterinary Science and Bacteriology
The Microbial Environment of the Calf With Diarrhea
the article addresses the microbial environment of the calf with diarrhea. The article starts with a background into the disease and it's treatment. In 1979, workers at the North Dakota State University veterinary science and bacteriology departments began a two year study on the microbial environment of the calf with diarrhea as a part of the NDSU Calf Diarrhea Research Program.In this study, the occurance, the number and pathogenic properties of the E. coli types found in soils from calving barns, calf pens, feedlots and pastures were investigated. This article covers the experimental methods. the results of this study indicated a reservoir of potentially pathogenic E. coli strains in barnyard soils contaminated with bovine feces. Of these strains were K99 pili. Strains isolated from diseased calves were K88 and K99 antigens - both associated with this disease in newborn calves
