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

Sanitation of Low Temperature Home Laundry

The pressures of sharply higher fuel prices and increasingly scarce supplies are causing consumers to consider each operation requiring energy in the home as a possible source of conservation. Often the recommendation is made for the use of cold water for laundry as a means of home energy conservation. Seldom is it mentioned that sanitation of laundry may be a problem when low water temperatures are used

Antibacterial properties of a peroxidogenic strain of <i>Streptococcus mitior</i> (<i>mitis</i>)

An antibacterial substance produced by a strain of Streptococcus mitior, and isolated from a human throat culture, was found to inhibit the growth of streptococci and staphylococci. The substance was characterized as hydrogen peroxide. </jats:p

Inclusion bodies in Plesiomonas shigelloides

Inclusion bodies were discovered in seven environmental isolates of Plesiomonas shigelloides and the P. shigelloides control (ATCC 14029). Differential staining indicated that the inclusion bodies may be composed of polyphosphates, and developmental stages of the bodies may occur. The inclusion bodies may be useful for rapid presumptive identification of this organism.</jats:p

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
