Historical cases of anthrax in Sweden 1916-1961. As in most European countries, anthrax was common in Swedish livestock during the centuries leading up to the mid-twentieth century. After 1957, the disease was regarded as practically extinct. However, in the past 7 years, three outbreaks have caused public alarm because of the risk of environmental contamination. Properly buried carcasses should present little risk of spore contamination, and instructions were in place to ensure this since the 1890s. However, as has been demonstrated in recent outbreaks, carcasses were not always adequately buried and viable spores may remain in some sites....
Efficacy and effects of various anti-crib devices on behaviour and physiology of crib-biting horses. Crib-biting is a common oral stereotypy.

Potential for iatrogenic coil embolization of the caudal cerebellar artery during treatment of internal carotid artery bifurcation in two horses with guttural pouch mycosis. 2 horses were examined for chronic nasal discharge secondary to unilateral guttural pouch mycosis. Results: Initial endoscopic examination of both horses confirmed the presence of a fungal plaque on the dorsomedial aspect of the medial compartment of the guttural pouch (auditory tube diverticulum) involving the internal carotid artery (ICA). No signs of hemorrhage or neurologic deficits were present at admission. Results: Transarterial stainless steel coil embolization of the affected ICA was performed under general anesthesia, with fluoroscopic guidance. During treatment, an aberrant branch o...
Design and testing of multiplex RT-PCR primers for the rapid detection of influenza A virus genomic segments: Application to equine influenza virus. The avian influenza A virus causes respiratory infections in animal species. It can undergo genomic recombination with newly obtained genetic material through an interspecies transmission. However, the process is an unpredictable event, making it difficult to predict the emergence of a new pandemic virus and distinguish its origin, especially when the virus is the result of multiple infections. Therefore, identifying a novel influenza is entirely dependent on sequencing its whole genome. Occasionally, however, it can be time-consuming, costly, and labor-intensive when sequencing many influenza...
Neonatal Care and Management of Foals Derived by Somatic Cell Nuclear Transfer. There are few reports on the birth of foals resulting from equine adult somatic cell nuclear transfer (NT). On evaluation of reports of 28 live-born adult somatic-cell NT (clone) foals, 3 died within 2 weeks of birth of complications. Approximately 50 % of all reported cloned foals had complications, some requiring aggressive supportive care. The most common abnormalities reported were neonatal maladjustment syndrome, enlarged umbilical remnant, and angular deformity of the forelimbs, similar to problems described in cloned cattle. In contrast, large offspring syndrome and gross abnormalities ...
