摘要:

This paper describes four cats with hyperadrenocorticism. Cat 1 showed polydipsia and polyphagia. Diabetes mellitus was initially diagnosed As the animal appeared to be insulin resistant, pituitary and adrenocortical function tests were performed and the diagnosis of hyperadrenocoricism was made. Resistance to the high‐dose dexamethasone suppression test was noticed in this cat. Pathological examination revealed a pituitary chromophobe adenoma.

摘要:

The pharmacokinetics of a combination of trimethoprim (TMP) and sulphadiazine (SDZ) after topical application to sucking piglets was compared with the pharmacokinetics after intramuscular injection. A long‐lasting and fairly constant SDZ/TMP concentration ratio in plasma was obtained after topical application. The mean plasma concentration of TMP ranged from 0.091 to 0.17 μg/ml and that of SDZ from 0.72 to 1.1 μg/ ml for at least 24 h. TMP and SDZ had different half‐lives after intramuscular injection. Transdermal delivery of a combined preparation of TMP/SDZ may be usable for colibacillosis of sucking piglets, although the bioavailability of the drugs is poor.

摘要:

Growing pigs were placed on feeds with high (Group A), medium (B) and low (C) dietary energy and were infected with a virulent stock ofT. brucei. Eight weeks later, the infected pigs were treated with isometamidium chloride at 1mg/kg live weight and all pigs were subsequently placed on a high energy diet to investigate their response to therapy.

摘要:

The necropsy findings of 85 cats that died up to six weeks after administration of injectable anaesthetics are described The most obvious findings in these cats were degeneration and necrosis of heart muscle fibres followed and related to time after the administration of the anaesthetics, by infiltration of predominantly mononuclear cells and by an increase in collagenous connective tissue. The lesions were most obvious on the inner side of the myocardium, indicating that hypoxic injury occurred during anaesthesia. The possible mechanism of the damage to the heart and its role in the pathogenesis of cardiomyopathy in the cat is discussed.

摘要:

To investigate howT. vivaxaffects metabolism in dwarf goats, nine wethers (infection group) given alfalfa pellets ad libitum were infected intravenously and food intake was recorded up to 49 days after infection in the infection group and in the control group (n=9). Controls received the same diet, ad libitum before infection and in restricted amounts after infection in order to obtain similar intakes in the two groups. Digestible organic matter intake (DOMI) and nitrogen balance (NB) were determined during four balance trials. All animals were bled regularly to measure parasitaemia, packed cell volume (PCV) and a number of serum metabolites.

摘要:

The epidemiology, therapy, and prevention ofM. bovisinfections are briefly reviewed In a survey begun in 1982M. boviswas found frequently in the respiratory of veal calves and beef cattle with respiratory problems. In replacement calves infected with respiratory disease in dairy herds, however, the organism has only been detected since 1986. Respiratory tract specimens collected from calves with respiratory disease were submitted for examination forM. bovisfrom 1986 to 1991 and originated from 83 herds. Mycoplasma bovis was detected in specimens from 59 of the herds, 20% of which were dairy herds and 80% fattening herds. Arthritis caused byM. boviswas observed in 12 herds until July 1991. Since 1976 when the first mastitis outbreak caused byM. boviswas diagnosedM. bovishas caused 14 more outbreaks. The number of diseased cattle varied from 1 tot 16 per farm, and clinical signs of mastitis varied from mild to severe. In all instances the infection has been eradicated from the herds. BecauseM. boviscan cause great losses in intensively reared cattle herds, it is advisable to separate purchased veal calves and beef cattle from dairy cattle to prevent further spread ofM. bovis.

摘要:

The prevalence, characteristics of the aetiological agent, clinical signs, pathological changes, pathogenesis, epizootiology, microbiological and serological diagnosis, prevention, and control of contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides subspecies mycoides SC type, are reviewed New aspects of the disease are discussed A renewed interest in this disease is important because of outbreaks in Southern Europe since 1980. When, at the end of 1992, the national borders of the countries of the European Community are abolished, it is conceivable that the disease will be introduced by cattle imported into CBPP‐free countries.

摘要:

A review is given of real and potential risks connected with the use of conventional and genetically engineered live and dead vaccines. Special attention is given to live carrier vaccines expressing one or more heterologous genes of other microorganisms. Because most carrier vaccines are still in an experimental phase, there is only limited experience with the risks of carrier vaccines. There are three potential risks of live carrier vaccines which will be discussed:

摘要:

Forty‐three dogs with canine ehrlichiosis were treated with longacting oxytetracycline (TLA) at a dose of 20 mg/kg. In order to eliminatie pain at the site of injection of TLA, varying doses of piroxicam were administered intramuscularly to the treated dogs. A minimum of 15 mg of piroxicam proved effective in eliminating pain and swelling at the TLA‐injection sites, while fever was eliminated with a minimum of 10 mg of piroxicam 24 hours post‐treatment. Rapid restoration or improvement of appetite in treated dogs was also observed after treatment with piroxicam and TLA. Both TLA and piroxicam were found to be suitable for use in dogs.
