Juvenile renal disease in Doberman Pinscher dogs.

Renal failure was diagnosed in 22 young Doberman Pinscher dogs. The clinical findings were anorexia, weight loss, vomiting, lethargy, polydipsia, polyuria, and dehydration. Laboratory findings were azotemia, hyperphosphatemia, lymphopenia, nonregenerative anemia, hypercholesterolemia, and proteinuria. The kidneys were characterized pathologically by glomerular sclerosis, cystic glomerular atrophy, tubular dilatation, tubular atrophy, mononuclear interstitial inflammation, interstitial fibrosis, interstitial mineralization, and hyperplasia of the collecting duct epithelium.

Inherited platelet delta-storage pool disease in dogs causing severe bleeding: an animal model for a specific ADP deficiency.

The nature of a disorder producing moderate to severe bleeding after minor trauma, venipuncture, and surgery was studied in 3 families of American cocker spaniel dogs. In the 5 affected dogs tested, platelet counts and measurements of plasma coagulant function and von Willebrand factor were normal. However, bleeding times were prolonged in 4 of the 5 affected dogs tested, and platelet aggregation in response to ADP and collagen was consistently abnormal in 3, suggesting that the bleeding disorder was due to abnormal platelet function. Measurements of 14C-serotonin uptake and retention by the affected platelets were normal. However, their ADP content was decreased, while their ATP content was normal, resulting in a mean ATP/ADP ratio of 8.32, compared to a mean ratio of 1.9 in normal canine platelets. Electron microscopy revealed that the number and appearance of the dense granules in the affected platelets were indistinguishable from those of normal controls. These studies suggest that this bleeding disorder results from a deficient delta-granule storage pool of ADP; given the normal serotonin uptake and retention by affected platelets and the apparently normal number of dense granules, the ADP deficiency may be the consequence of a selective defect in delta-granule ADP transport. Additional studies of this unique platelet disorder will provide an opportunity to understand the mechanism of adenine nucleotide storage in platelet delta-granules.

A study of skin diseases in dogs and cats. II. Microflora of the normal skin of dogs and cats.

A study of the microflora of the normal skin was undertaken in 10 dogs and 10 cats. Swabs were taken from the surface of the skin at 7 different sites (Fig. 1). Micrococcus spp., alpha-hemolytic streptococci, and Acinetobacter spp. were found consistently in both species. Staphylococcus aureus was isolated from 9 dogs and 4 cats, and staphylococcus epidermidis from 7 dogs and 5 cats. Beta-hemolytic streptococci, Corynebacterium spp., Bacillus spp., Escherichia coli, Proteus mirabilis, Pseudomonas spp., and Alcaligenes spp. were found sporadically.

Skin diseases of old dogs and cats.

The ageing process tends to predispose dogs and cats to certain skin diseases. Impaired immunosurveillance is believed to render the animals more susceptible to neoplasia which can affect any organ including the skin. Endocrinopathies are also more common in older animals. There are some diseases of internal organs which can affect the skin, and some of these tend to occur with increased frequency in old animals. Finally, seborrhoeic diseases are either more common in older animals, or become increasingly severe with age.

Properties of serological group B streptococci of dog, cat and monkey origin.

This study was designed to identify and characterize further Streptococcus agalactiae isolated during routine diagnostics from three diseased dogs and a cat, as well as from the inner organs of a monkey which died on a sepsis with beta-haemolytic streptococci. The cultures could be identified as streptococci of serological group B by cultural, biochemical and serological properties and by restriction fragment length polymorphism analysis of polymerase chain reaction (PCR)-amplified 16S ribosomal DNA. A further characterization of the isolates by serotyping and by determination of antibiotic resistances revealed a close relationship of these isolates to the human biotype of this species.

Understanding the genetics of autoimmune disease: two loci that regulate late onset Addison's disease in Portuguese Water Dogs.

Addison's disease, an immune-mediated disorder caused by destruction of the adrenal glands, is a rare disorder of Western European populations. Studies indicate that the disorder is polygenic in nature, involving specific alleles of the CTLA-4, DRB1*04 and DQ, Cyp27B1, VDR and MIC-A and -B loci. A similar immune form of Addison's disease occurs in several breeds of domestic dog, with frequencies ranging from 1.5 to 9.0%. The high frequency of the disease in domestic dog breeds likely reflects the small number of founders associated with many breeds, subsequent inbreeding, and the frequent use of popular sires. The Portuguese Water Dog (PWD) is a significantly affected breed. An analysis of 11,384 PWDs surveyed between 1985 and 1996 suggests a breed-specific disease incidence of 1.5%. As with humans, the disease is typically of late onset. This study involves a genetic comparison of Addison's disease in the PWD to the analogous disease in humans. The study is facilitated by the existence of complete pedigrees and a relatively high degree of inbreeding among PWDs. The breed originated from 31 founders, with 10 animals responsible for 90% of the current gene pool. We describe, specifically, the identification of two disease-associated loci, on Canis familiaris (CFA) chromosomes CFA12 and 37, which are syntenic with the human DRB1 histocompatibility locus alleles HLA-DRB1*04 and DRB1*0301, and to a locus for immunosuppression syntenic with CTLA-4. Strong similarities exist therefore in the complex genetic background of Addison's disease in humans and in the PWD. With the completion of the canine and human genome sequence, the purebred dog is set to become an important comparative model for Addison's as well as other human immune disorders.

Clinical and pathological features of protein-losing glomerular disease in the dog: a review of 137 cases (1985-1992).

Medical records of 137 dogs with protein-losing glomerular disease (PLGD) were evaluated. Cases with amyloidosis (23%) were more likely to be azotemic at presentation, with significantly greater proteinuria and hypoalbuminemia than those cases with glomerulonephritis (GN; 77%). The prognosis for all cases was poor, with a median survival time of just 28 days. The most common causes of death in cases with idiopathic disease were chronic renal failure (69.5%) or thromboembolic complications (22.2%). Progression of glomerular disease was unpredictable, with no apparent correlation between survival time and biochemical parameters at presentation.
