A Japanese Black calf six and a half months old showed signs of anorexia and constipation for eight days. It failed to respond to any medical treatment during this period. The right sublumbar fossa was mildly distended. A resonant ping was audible by simultaneous auscultation and percussion over the whole right flank on the sixth day of illness. A tentative diagnosis of cecal volvulus was made. laparotomy was performed through the right flank under local anesthesia. Manual examination of the abdominal cavity detected the distended and displaced cecum filled with a large amount of gas and gastric juice, and adhesions of the omentum to the intestinal wall around the ileocecocolic junction. As the site of adhesion was thickened with proliferated connective tissue and the intestinal lumen narrowed at this site, the cecum and a proximal part of the colon were resected and then end-to-end anastomosis was made between the ileum and the colon. Postoperative recovery was uneventful with defecation on the day after operation and the appetite resumed gradually. During the postoperative period of four and a half months, the serum magnesium level was high temporarily and returned later to a normal one.
To determine the incidence of Keratinophilic fungi on hair of dogs and cats without visible skin lesions, a survey was conducted in 9 small animal hospitals in Kyoto for one year. Specimens were collected from the hair coat of 371 dogs and 71 cats by brushing with a sterilized tooth-brush. Each sample was cultured on soil plate with horse hair placed as a bait. As a result, the specimens from 60 dogs (16.2%) and 9 cats (12.7%) yielded positive cultures of Chrysosporium keratinophilum (24 strains), C. tropicum (18), Anixiopsis fulvescens var. stercoraria (2), Microsporum gypseum (4), Trichophvton ajelloi (1), Alternaria sp.(29), Sepedonium sp.(1), Fusarium sp.(1), and Scopulariopsis sp.(1). A higher percentage of isolation was found in animals of outdoor breeds than in those of indoor breeds and during the months from April to October than during the other months. It is for the first time that A. fulvescens var. stercoraria was isolated from dogs and cats.
Seventeen rats and 59 mice were fed a diet containing 50% of tallow hardened by saturation with hydrogen molecules (HT), untreated, non-hardened fat (NT), or stearic acids. As a result, fat necrosis was produced in rats fed HT for 7-21 weeks. These rats showed the same histopathological changes as the cattle previously reported. No mice suffered from fat necrosis.
Piglets were administered with a daily dose of 10 mg of sulfamonomethoxine (SMM) per kg of body weight mixed with feed for 30 days beginning at the time of weaning. At the end of the period of administration the rate of detection of B. bronchiseptica was 6.3% among these piglets and 43.8% among untreated control ones. At the time of shipment the positive rate of agglutinating antibody was 68.8% in the former and 87.5% in the latter. The rate of occurrence of lesions of the nasal conchae was 25.5% in the former and 68.8% in the latter. SMM was concluded to have a preventive effect against swine atrophic rhinitis.
