Diskospondylitis in a kennel of dogs: clinicopathologic findings.

Selected aspects pertaining to the cause and pathogenesis of diskospondylitis were investigated in a kennel of 45 Airedale Terriers. Diskospondylitis was detected via spinal radiography in 17 male and 14 female dogs. Bacteria isolated from the coat, vagina, and urine of affected Airedales were not statistically different from those isolated from clinically normal Airedales. Serologic evidence of Brucella canis infection was not detected. There was no difference in response to thyrotropin stimulation tests between affected and clinically normal dogs. Necropsy findings in affected dogs included hypercellular renal glomeruli and pulmonary arterial thrombi.

Induced paragonimiasis in cats: clinical signs and diagnosis.

Twenty-eight specific-pathogen-free cats were inoculated with 14 to 50 metacercariae of Paragonimus kellicotti obtained from the hearts of naturally infected crayfish. Young flukes excysted in the intestine of cats and appeared in the peritoneal cavity from 1 to 14 days after inoculation (DAI) and in the pleural cavity from 5 to 23 DAI. Flukes penetrated the pulmonary parenchyma and formed hemorrhagic subpleural lesions within 5 weeks after inoculation. Marked eosinophilia developed between 2 and 12 weeks after inoculation. Fluke-containing pulmonary lesions were detected by radiography 3 to 4 weeks after inoculation. Lesions developed most frequently in the right caudal lung lobe. Clinical signs were mild and did not appear until 4 weeks after inoculation. Thereafter, cats appeared dull and coughed intermittently. One cat became dyspneic due to pneumothorax. Paragonimus eggs were first detected at the 34th DAI, using a fecal sedimentation technique.

Perineal herniorrhaphy: perioperative data from 100 dogs.

One hundred dogs (83 intact males, 15 castrated males, and two intact females) underwent 110 perineal herniorrhaphy procedures. Mixed-breed dogs (n = 32), miniature poodles (n = 14), Boston terriers (n = 11), and Pekingese (n = 9) were represented most frequently. Perineal swelling (n = 48) and a perineal defect on rectal palpation (n = 31) were common clinical signs. Twenty dogs had urinary bladder retroflexion and were significantly more likely to have elevated serum urea nitrogen and creatinine concentrations, hyperkalemia, hyperphosphatemia, and neutrophilic leukocytosis. Only five of 43 dogs evaluated radiographically had prostatomegaly. Of 30 dogs receiving oral barium, all had rectal deviation. The most frequent complications during the hospitalization period were incisional (n = 35), followed by rectal prolapse (n = 9), tenesmus (n = 8), and depression (n = 8). Fifty-six of 70 dogs with follow-up had no complications.

Traumatic ear canal separations and para-aural abscessation in three dogs.

Three dogs were presented for para-aural abscessation. Ear canal separations were suspected preoperatively, based on histories of trauma, physical examination findings of minimally inflamed external ear canals with abrupt endings, and radiographic evidence of discontinuity of the ear canals. Concurrent otitis media, based on radiographic findings, was diagnosed in all three dogs. Disruptions of the external ear canals were confirmed at surgery, and the dogs each responded to total ear canal ablation and lateral bulla osteotomy.

Large bowel transit times using radiopaque markers in normal cats.

Seven normal, young adult, female cats each had its colon evacuated with warm-water enemas (at 24 hours, 12 hours, and one hour) before oral administration of a gelatin capsule containing 20 radiopaque markers to determine normal colonic transit times. Abdominal radiographs were taken twice daily until all markers were expelled. There were no significant differences between animals or trials (p = 0.05 or less). Markers accumulated in the first section of large bowel within eight hours. Evacuation from the colon took another 40 hours. Cecum (right side midline), left side midline, and rectum were defined radiographically. This study establishes large bowel transit times in normal cats and provides the basis for similar evaluation in constipated cats.
