Canine Hepatitis Associated with Intrahepatic Bacteria in Three Dogs.

This case report describes the detection of intrahepatic bacteria in formalin-fixed paraffin-embedded histopathological sections from three dogs with neutrophilic, pyogranulomatous, or lymphoplasmacytic hepatitis and cholangiohepatitis. In each of these cases, eubacterial fluorescence in situ hybridization enabled colocalization of intrahepatic bacteria with neutrophilic and granulomatous inflammation in samples that were negative for bacteria when evaluated by routine hematoxylin and eosin histopathology augmented with histochemical stains. Positive responses to antimicrobial therapy were observed in of 2 out of 2 patients that were treated with antimicrobials.

Cycad Palm Toxicosis in 14 Dogs from Texas.

The goal of this study is to report clinical information, diagnostic findings, and treatment modalities; assess variables that may help distinguish survivors from nonsurvivors; and review the outcome of cycad palm toxicosis in dogs. Fourteen client-owned dogs with confirmed cycad palm ingestion were identified by reviewing the medical record database at Gulf Coast Veterinary Specialists. Information on signalment, time of ingestion to presentation, clinical signs, physical examination findings, initial and peak/nadir laboratory abnormalities, radiographic and ultrasonographic findings, treatment modalities, liver histopathology, and clinical outcome was retrieved.

Disseminated protothecosis associated with diskospondylitis in a dog.

A 6 yr old female Labrador retriever was evaluated for an acute onset of difficulty walking and a head tilt. Initial physical examination revealed bilateral retinal detachment, a left-sided head tilt, positional rotary nystagmus, and lumbar hyperpathia. Pertinent preliminary diagnostic findings included systemic hypertension, bony lysis and adjacent sclerosis of the vertebral endplates of the first and second lumbar vertebrae, and positive urine and blood cultures for a yeast identified as Candida spp.

Pollakiuria and stranguria in a Labrador retriever with penile HSA.

An approximately 8 yr old castrated male Labrador retriever presented for evaluation of weight loss, stranguria, and pollakiuria. Lysis of the proximal one-third of the os penis was diagnosed on abdominal radiographs, and a positive contrast urethrography revealed a smoothly marginated filling defect along the dorsal aspect of the urethra at the level of the radiographically observed osteolysis. Regional ultrasound revealed an echogenic mass at the proximal aspect of the os penis with a severely irregular and discontinuous periosteal surface.

Surveillance of infections associated with intravenous catheters in dogs and cats in an intensive care unit.

Positive catheter-tip culture rates and risk factors associated with bacterial colonization of intravenous (i.v.) catheters were assessed in dogs and cats.

Prevalence of Bartonella species, haemoplasma species, Ehrlichia species, Anaplasma phagocytophilum, and Neorickettsia risticii DNA in the blood of cats and their fleas in the United States.

Ctenocephalides felis were killed and collected from 92 cats in Alabama, Maryland, and Texas. The fleas and blood from the corresponding cat were digested and assessed in polymerase chain reaction assays that amplify DNA of Ehrlichia species, Anaplasma phagocytophilum, Neorickettsia risticii, Mycoplasma haemofelis, 'Candidatus M haemominutum' and Bartonella species. DNA consistent with B henselae, B clarridgeiae, M haemofelis, or 'Candidatus M haemominutum' was commonly amplified from cats (60.

Antimicrobial drug use in veterinary medicine.

Recognizing the importance of antimicrobial resistance and the need for veterinarians to aid in efforts for maintaining the usefulness of antimicrobial drugs in animals and humans, the Board of Regents of the American College of Veterinary Internal Medicine charged a special committee with responsibility for drafting this position statement regarding antimicrobial drug use in veterinary medicine. The Committee believes that veterinarians are obligated to balance the well-being of animals under their care with the protection of other animals and public health. Therefore, if an animal's medical condition can be reasonably expected to improve as a result of treatment with antimicrobial drugs, and the animal is under a veterinarian's care with an appropriate veterinarian-client-patient relationship, veterinarians have an obligation to offer antimicrobial treatment as a therapeutic option.
