Three cutaneous phymas egg to small fist in size occurred on the lower neck and the outside of the bilateral thighs of an 80-day-old female puppy (Tosabreed) which had been injected by the owner with calcium gluconate solution for the treatment of rickets. The phymas were hard with slight pain and heat and separated in subcutaneous tissue from the skin. Candida zeylanoides was isolated purely from them, which disappeared within 5 days after the oral administration of nystatin. An inflammation caused by calcium gluconate solution might be related to the etiology of this disorder which was accompanied with the accidental growth of C. zeylanoides.
White muscle disease was observed in 11 calves 31 to 77 days old of the indigenous Japanese Black breed in Shimukappu, Kamikawa, Hokkaido over a period from April to June, 1983. Dysstasia, dysbasia, palpitation, tachypnea and stiffening of the trunk muscle were main clinical signs of the disease. A decrease was seen in α-tocopherol and seleniumconcentration and a remarkable increase in GOT, GPT, LDH (especially LDH4 and LDH5), and CPK activity in the serum. The affected calves showed a dramatic response to the oral administration of vitamin E and antibiotics and allopathic treatment. Of them, eight recovered and three died suddenly.Degeneration of the trunk and cardiac muscles was noticed. The calves and their mothers had mainly been fed hay and silage in which the selenium content was obviously low. It was assumed that the outbreak of white muscle disease might be due to a deficiency in vitamin E and selenium.
The occurrence and nature of abomasal foreign bodies were investigated in 1, 976 clinically healthy cows in mass-screening with an X-ray car for large animals within 23 months period from January 1981 to November 1982 in northern and eastern districts of Hokkaido.Metallic foreign bodies (MFB) and sand-like substance were observed in the abomasum in 35.3% and 96.5% of the cows, respectively. This result suggested that most of the clinically healthy cows might always be exposed to the occurrence of traumatic abomasitis and/or abomasal ulcer, and turned down the theory that MFB were very seldom encounted in the abomasum. Of the cows, 826 had a magnet in the reticulum. MFB were found in the abomasum in 25.7% of them.Abomasal MFB were detected from 42.2% of 1, 147 cows which had no magnet in the reticulum. The presence of a magnet in the reticulum was effective to some extent to prevent the migration of MFB to the abomasum.
Amyloidosis occurred in layer chickens 4 to 5 months old. Clinically, it caused anemia and respiratory signs. Main gross lesions were an enlargement of the liver and clouding and thickening of the air sac, frequently containing cheesy substances. Histopathologically, the birds were affected with marked chronic respiratory diseases, including air sacculitis. Amyloid deposition was seen in Disse's spaces of the liver, and blood vascular walls and connective tissues of various organs, including liver, trachea, bronchi, air sacs, spleen, and mesentery. It was considered that the amyloidosis occurred secondarily to chronic respiratory disease.
Of 420 domestic and stray dogs investigated in Kanagawa Prefecture from October, 1982 to December, 1983, 275 (65.5%) were positive for intestinal helminths. The species of helminths detected and their incidence rates were as follows: Metagonimus sp. in 2 dogs (0.5%), Manson's pseudophyllidean tapeworm in 2 (0.5%), canine whipworm in 132 (31.4%), canine roundworm in 86 (20.5%), hookworm in 160 (38.1%), and Strongyloides spp. in 5 (1.2%). In dogs and domestic cats, experimental infection was carried out with the Strongyloides spp. obtained. As a result, the worms were identified as Strongyloides planiceps and S. stercoralis. The former was thought to be of more common occurrence than the latter in domestic and stray dogs in Kanagawa Prefecture.
A two-month-old female Japanese cat affected with congenital diaphragmatic hernia was treated surgically. Because the defect of the hernia was too large, an autofascia of the obliquus externus abdominis muscle was applied to repair of the diaphragm. The animal recovered without complication.
A prosthesis was made of dental acrylic resin for a male white stork, Ciconia ciconia boyciana, which had 2/3 of its upper bill broken by an accident in a cage. Many attempts had been done in vain to repair the bill. Firstly, 4-META (4-methacryloxyethyl trimellitate anhydride) with TBB-O as a catalyst was used as adhesive, but the substitute came off 24 days later because of the natural growing of the bill. Finally, the artificial bill was tied with a stainless steel wire covered with a silicone gum tube through the nostrils with satisfactory results.
The Government has established a General Conference on Fish Disease Control, which has a Vaccine Section in its Committee on Medicines. Protective immunity to infectious diseases has been recognized in fish by a number of investigators in the fields of veterinary and fishery sciences. Especially in the field of veterinary science, some fish vaccines have already been developed by the Committee in Fish Vaccines of the Association of Biological Products for Animal Use. Some administrative problems remain to be settled, as well as those on the production and supply of fish vaccines in order to diminish economic losses and to dissolve some problems on food hygiene.
