Molecular and immunohistochemical detection of assemblage E, Giardia duodenalis in scouring North Dakota calves.
Despite many reports on the shedding of Giardia parasites by scouring calves, the role of Giardia as a cause of calf diarrhea is still controversial. To elucidate the role of Giardia duodenalis in calf scours, diagnostic samples from 189 scouring calves were tested by different assays during a 1-year-study period. Giardia antigens were detected in 22/189 scouring calves by a fecal-based enzyme-...
متن کاملAntibiotic use
Is an antibiotic needed? Many diseases are not a result of bacterial infection and, especially when not severe, do not need antibiotics to manage them. Relevant examples include mild calf scours and outbreaks of coughing without other signs among growing cattle. Even in more severe cases of scour and pneumonia, the effect of antibiotics may be to protect the animal from secondary infection rath...

متن کاملCharacterization of heat-stable enterotoxin from a hypertoxigenic Escherichia coli strain that is pathogenic for cattle.
An enterotoxigenic Escherichia coli (ETEC) strain isolated from a calf with clinical scours was found to produce over 17- to 60-fold more heat-stable enterotoxin (STa) than four laboratory-adapted bovine ETEC strains. The purified STa of this strain was identical to those produced by other ETEC strains. A severe form of scours was induced in 5- to 15-day-old colostrum-fed calves and in 1- to 2-...
متن کاملThe Bacteriology of the Intestinal Tract of Young Calves with Special Reference to the Early Diarrhea ("scours")
New-born calves receiving no colostrum, or else receiving it after some delay, may die of Bacillus coli septicemia, of which scours is a local manifestation. Calves receiving an insufficiently protective dose of colostrum may become victims of various bacterial diseases such as arthritis, nephritis, omphalitis, and possibly pneumonia. Calves receiving a sufficient dose of colostrum may still de...
