The objective of this study was to determine the association between Equine Rotavirus (ERV) infections and gastric and/or duodenal lesions. An endoscopic examination of the stomach and duodenum and an examination of stool samples for the presence of ERV were performed on 41 thoroughbred foals with diarrhea. 58.5%(24/41) of the stool samples tested positive for ERV, while 95%(38/41) of the stomachs and 33.3%(7/20) of the duodenums were found to have lesions. There was no association between the severity and prevalence of gastric lesions and the presence of ERV. The prevalence of duodenal lesions was significantly higher (P<0.05) when test results for ERV were positive (54.6%) than negative (10.0%). Clinical signs were not affected by the presence of ERV. It is reasonable to conclude that most foals with diarrhea, regardless of the presence or absence of ERV, have gastric lesions, and that lesions of the duodenum are associated with ERV.
A penile injury that occurred while collecting semen from a bull proved to have serious consequences due to a lengthy healing time and subsequent economic loss. Surgical treatment was performed on the affected part of the penis by using the method of pudendal nerve anesthesia. Seven bulls (Japanese Black Beef Cattle) suffered penile injury during semen collection, and the penis was revealed from the preputium by pudic nerve blocking. In all cases, bleeding or growth of the connective tissue was confirmed by a laceration of the fibrous coat of the penis. Extra connective tissue was removed in some cases, and the laceration was sewn up by simple interrupted suture using the Synthe Sorb. In the affected area, good cicatrization was observed after surgical treatment, and semen collection was possible within 70 days. For cases of penile injury or damage in bulls, it is believed that the method of pudendal nerve anesthesia and surgical treatment may be very effective.
An acutely stressed group and a non-stressed group of ten clinically healthy beagles were compared in terms of the peripheral lymphocyte number following administration of capsulated extract of Hatakeshimeji (Lyophyllum decastes Sing.). Lymphocyte numbers were higher in dogs that received an administration of the capsulated extract, irrespective of stressed or non-stressed. There was a significant difference in the non-stressed group.
A seven-month-old Italian greyhound with bilateral exophthalmos was diagnosed with immune-mediated extraocular myositis (EOM) according to results of neurological, magnetic resonance imaging (MRI) and serological examinations. A histpathological view from a biopsy has been considered necessary for a definitive diagnosis of inflammatory myopathies. In this report, the authors also identified MRI findings, such as enlargement and marked contrast enhancement of extraocular muscles, along with the presence of an IgG autoantibody in the serum. We can apply these findings to EOM diagnosis.
