摘要:

Pasteurella haemolyticacauses two distinct disease syndromes in sheep.P. haemolyticabiotype A causes septicaemia in young lambs and pneumonia in all ages of sheep. Biotype T produces an acute systemic disease affecting principally the upper alimentary tract and lungs in young adult sheep. The bacteriology, epidemiology and clinical and necropsy findings of the two diseases are described and the current situation regarding their experimental reproduction and immunology is reviewed.

摘要:

Water balance studies were performed in 7 experimental dogs before and during a period of cortisol‐induced polyuria and in one dog with spontaneous hyperadrenocorticism before and after removal of an adrenocortical carcinoma. Measurements of urine and plasma osmolality and plasma arginine vasopressin concentration were made at regular intervals during the water deprivation studies. The results indicate that cortisol does not block the release of vasopressin but interferes with its action in the kidney.

摘要:

The minimal inhibitory concentrations (M1C) of tiamulin and tylosin for mycoplasma. Gram‐positive, and Gram‐negative micro‐organisms isolated from chickens were determinated by the agar dilution method. Median M1C values for tiamulin againstMycoplasma gallisepticum(0.05 μg/ml) andMycoplasma synoviae(0.10 μg/ml) were 2 to 4 times lower than the corresponding values for tylosin. Tiamulin was also slightly more effectivein vitroin inhibitingEscherichia coli, Pasteurella multocida,and beta‐haemolytic streptococci than was tylosin. Groups of chicken were offered tiamulin medicated drinking water at rates of 125 and 250 mg/litre for 48 hours. Average serum tiamulin concentrations were 0.38 and 0.78 μg/ml, respectively. When tylosin tartrate was added to the drinking water at 500 and 700 mg/litre, average serum drug levels were 0.12 and 0.17 μg/ml, respectively.

摘要:

Information published between 1567 and 1978 on this subject contains at least 223 titles. They cover medical and veterinary as well as biological aspects. Full bibliographical details of the publications are given. A subject index (to tick species, host species, and diseases transmitted) increases the availability of the data included. Some of the more interesting results of the study are discussed in a short introduction.

摘要:

Anti‐bovine lymphocyte serum (ABLS) had been prepared in horses with calf thymocytes as antigen and its effects in calves following parenteral administration were studied. The optimal dose was found to be one ml/kg body weight. The A BLS suppressed both the T and B cell functions. The former was indicated by the disturbed response to sheep erythrocytes injections, by the decreased number of spontaneous E rosette forming lymphocytes, the prolonged survival of skin allografts and the significant inhibition of the delayed hypersensibility skin reaction (tuberculination) following administrationof Mycobacterium microti.The latter was based on the disturbed response to a subcutaneous dose of tetanus toxoid. The reaction of lymphocytes of ABLS treated calves to phytohemagglutinin and poke weed mitogen was also inhibited. The disturbed reactions of the T and B cells might be among others based on the strong reduction of lymphocytes in the blood circulation by ABLS (up to 10–20%).
