In 2 goat herds, one infected with Gorynebacterium pseudo-tuberculosis and one free from the infection,, goats were examined for superficial swellings on the shoulder and chest. All animals in this study had been vaccinated against paratuberculosis before the age of 4 weeks. The vaccine had been applied subcutaneously behind the shoulder. Twenty-two of 40 (55 %) and 31 of 45 (69 %) goats had such lesions in the infected and non-infected herds, respectively. The difference between the herds was not significant, P > 0.05.Swellings found behind the shoulder in 19 goat carcasses derived from 4 herds in which G. pseudotuberculosis infection occurred were examined bacteriologically. No bacteria could be isolated from such lesions in 15 animals, while G. pseudotuberculosis in pure culture was isolated from 3 carcasses, and a mixed bacterial flora from the re-maining carcass. Bacteria could not be isolated from lesions situated behind the shoulder in 7 carcasses from 3 herds free from G. pseudo-tuberculosis infection.It is concluded that most swellings on the shoulder and chest in goats were granulomas resulting from vaccination against paratuber-culosis. 相似文献

Gross swellings of the equine frontal area are most commonly caused by the poorly understood disorder of nasofrontal suture line periostitis that is usually self‐resolving, sinus cysts that are highly amenable to treatment, sinus tumours that in contrast usually respond poorly to treatment and facial trauma that may later lead to nasofrontal suture line periostitis. Other causes of conchofrontal sinus disease such as intrasinus progressive ethmoid haematoma, primary sinusitis and dental sinusitis seldom cause gross swellings of the overlying bones. 相似文献
