Branchial cyst in a dog     

D M Clark  M Kostolich  D Mosier 《Journal of the American Veterinary Medical Association》1989,194(1):67-68

A 7-year-old spayed German Shorthaired Pointer was determined to have a branchial cyst in the subcutaneous tissues of the cervical/facial area. Treatment had been attempted by aspiration and placement of drains, but without success; the final diagnosis was made after microscopic examination of the wall of the excised cyst. The means by which fluctuant swellings in this region may be differentiated are anatomic location and examination of full-thickness biopsy specimens of cyst walls.  相似文献   

Serum amyloid A protein concentration measured by radial immunodiffusion in Abyssinian and non-Abyssinian cats   总被引：1，自引：0，他引：1  

S P DiBartola  J A Reiter  J B Cornacoff  G J Kociba  M D Benson 《American journal of veterinary research》1989,50(8):1414-1417

Serum amyloid A (SAA) protein concentration was determined by use of radial immunodiffusion (RID) in 4 groups of cats: Abyssinian cats with amyloidosis, healthy Abyssinian cats without clinical evidence of amyloidosis, hospitalized non-Abyssinian cats, and clinically normal non-Abyssinian cats. Mean SAA concentration in Abyssinian cats with amyloidosis was significantly (P = 0.05) higher than mean SAA concentration in healthy Abyssinian cats without clinical evidence of amyloidosis and in hospitalized non-Abyssinian cats. Mean SAA concentration in clinically normal non-Abyssinian cats was significantly (P = 0.05) lower than mean SAA concentration in healthy Abyssinian cats without clinical evidence of amyloidosis and in hospitalized non-Abyssinian cats. Affected and healthy Abyssinian cats, however, could not reliably be distinguished on the basis of SAA concentration, because of the wide range of SAA values in these 2 groups of cats.  相似文献

Serological survey of the incidence of Hypoderma bovis in cattle in 1988     

I J Sinclair  D W Tarry  D A Wassall 《The Veterinary record》1989,124(10):243-244

Sera from 74,502 cattle from 3087 farms in England and Wales were tested for the presence of antibodies against Hypoderma bovis in the spring of 1988. Twenty-nine positive sera were identified on 18 premises and these animals were treated; an examination of 6030 sera taken from 108 neighbouring herds identified another 17 seropositive animals on 10 farms in Devon, Cornwall, Lancashire, Shropshire and Powys, indicating that these counties still harbour populations of warble fly.  相似文献   

Treatment of Humeroulnar Subluxation with a Dynamic Proximal Ulnar Osteotomy A Review of 13 Cases     

STEPHEN D. GILSON DVM    DONALD L. PIERMATTEI DVM  PhD  DiplomateACVS  PETER D. SCHWARZ DVM  DiplomateACVS 《Veterinary surgery : VS》1989,18(2):114-122

Humeroulnar subluxation was treated surgically in 13 dogs with 18 affected elbows using a proximal osteotomy of the ulna that allowed the ulna to elongate dynamically. Distal humeroulnar subluxation was secondary to premature closure of the distal ulnar physis in 16 elbows. One distal subluxation was secondary to a radioulnar synostosis, and one proximal subluxation developed after premature closure of the distal radial physis. The mean follow-up time was 22 months. Twenty-eight percent of the elbows were judged to have excellent results, 22% good results, 50% fair results, and none was judged to have a poor outcome. The presenting lameness grade and the severity of preoperative and postoperative humeroulnar subluxation had significant correlations with the prognosis. Associated orthopedic abnormalities and complications of concurrent surgical procedures affected the outcome in several dogs. Overall, the dynamic proximal ulnar osteotomy was a simple and effective technique for the treatment of uncomplicated humeroulnar subluxation.  相似文献   

Comparative susceptibility of caponized and uncaponized tom turkeys to Pasteurella multocida.     

R C Friedlander  L D Olson  E L McCune 《Avian diseases》1992,36(1):97-100

When susceptibility to virulent Pasteurella multocida was compared, there was no significant (P greater than 0.05) difference between caponized and uncaponized tom turkeys. Neither was there any significant (P greater than 0.05) difference between the surviving caponized and uncaponized toms in the development of serum anti-P. multocida antibody. However, at 28 weeks of age, the average live body weight of the caponized toms was significantly (P less than 0.05) lower than that of the uncaponized toms. Turkeys were caponized when 9 weeks old, and different groups were exposed to P. multocida when 13, 18, 23, and 28 weeks old.  相似文献   

Tuberculosis in wild seals and characterisation of the seal bacillus   总被引：3，自引：0，他引：3  

DV COUSINS  SN WILLIAMS  R. REUTER†  D. FORSHAW†  B. CHADWICK§  D. COUGHRAN¶  P. COLLINS#  N. GALES 《Australian veterinary journal》1993,70(3):92-97

SUMMARY Tuberculosis was diagnosed in 3 otariid seals found dead on beaches at 3 locations on the south coast of Western Australian between May 1990 and March 1991. This confirms that tuberculosis is present in the 2 native seals (Neophoca cinerea and Arctocephalus forsteri) in Western Australian waters. Mycobacterium sp isolated from the lungs of 2 of the seals were studied to determine the similarity of the strains to each other, to the strains isolated during 1986 from Australian sea lions and New Zealand fur seals kept in captivity at a marine park near Perth, Western Australia, and to a strain isolated in 1988 from a seal trainer who worked with the infected captive seals for 3 years. After restriction endonuclease analysis (REA) with the endonucleases Bst Ell, Bcl I and Pvu II, one of the wild seal strains appeared to have identical DNA fragment patterns to the strains from the captive seals and the seal trainer. The other wild seal isolate had identical REA profiles using Bst EII and Bcl I, but a minor difference was detected using Pvu II. Differences in these isolates were more clearly seen in restriction fragment length polymorphisms after hybridisation with two DNA probes. The secretory protein MPB70, present in M bovis, was not detected in wild seal isolates using sodium dodecyl sulphate polyacrylamide gel electrophoresis and Western blotting techniques. Analysis of protein and DNA fragment profiles indicated that seal tuberculosis isolates form a unique cluster within the M tuberculosis complex.  相似文献   

BACTERIAL ENDOCARDITIS WITH THROMBUS FORMATION AND ABSCESSATION IN A HORSE     

Melissa trogdon  Hines  DVM  PhD  Jerry R.  Heidel  DVM  PhD  David D.  Barbee  DVM  MS 《Veterinary radiology & ultrasound》1993,34(1):47-51

A 2.5 year old Appaloosa stallion with progressive weight loss and a heart murmur was diagnosed as having vegetative endocarditis of the right atrioventricular valves with a mass in the right atrium. The ultrasonographic appearance of the lesion was characterized by extreme reverberation. On postmortem examination, a 9 cm diameter thrombus was found within the right atrium and auricle, occupying approximately 80% of the chamber volume. Additionally, a lenticular abscess extended throughout the parietal cusp of the right atrioventricular valve. Histologic examination revealed that the lesions were septic with numerous gram positive cocci in short chains, suggestive of Streptococcus equi , and gram negative rods.  相似文献   

Thrombocyte aggregation in the cat     

S Hart  I Nolte 《Tier?rztliche Praxis》1991,19(4):413-418

Platelet aggregation in healthy and sick cats after adding various aggregating agents is described. Feline platelets aggregate irreversibly in response to 0.15-1.0 micrograms/ml collagen, 1 microM ADP, 0.3 IU/ml test-thrombin and 0.71 NIH/ml Topostasin. Epinephrine, ristocetin and kaolin failed to cause aggregation. The aggregation function was decreased in a cat with liver damage and icterus; in 2 cats with uremia platelet aggregation was normal. Acetylsalicylic acid (ASA) (10 mg/kg iv) inhibits platelet aggregation in the presence of collagen in low concentrations; high concentrations of collagen succeeded in inducing platelet aggregation.  相似文献   

Valvular pulmonic stenosis in bullmastiffs     

R. Malik  D. B. Church  G. B. Hunt 《The Journal of small animal practice》1993,34(6):288-292

Six bullmastiffs with congenital heart disease were evaluated over a three-year period. In all the cases the problem was shown to be dysplasia of the pulmonary valve. Five cases were male, one was female. All dogs available to follow-up developed signs of cardiac decompensation. Bullmastiffs must be added to the list of breeds in which valvular pulmonic stenosis is encountered frequently.  相似文献
