A German Shepherd Dog was evaluated for clinical signs of multifocal, progressive brain disease. Despite supportive care, the dog died shortly after hospital admission. Granulomatous meningoencephalitis with intralesional fungal hyphae was diagnosed postmortem. The fungus was identified as Sporobolomyces roseus by polymerase chain reaction amplification and sequencing of the ITS2 region. 相似文献

A 2.5-year-old spayed female German Shepherd Dog was referred for evaluation of progressive anemia, lethargy, and weight loss. Seventeen days earlier, the dog had received a whole blood transfusion to manage hemorrhage after ovariohysterectomy. Mild fever, splenomegaly, and thrombocytopenia were also identified. Von Willebrand disease and Babesia gibsoni infection were diagnosed. Because of the serologic cross-reactivity of B gibsoni and B canis in the immunofluorescent antibody assay for IgG antibodies against these organisms, polymerase chain reaction amplification of parasite DNA was required to identify the infecting Babesia sp. The source of the B gibsoni infection was traced to an apparently healthy American Pit Bull Terrier blood donor. Despite resolution of clinical signs in the dog of this report, a series of antiparasitic treatments failed to eliminate the B gibsoni infection. Screening of potential blood donor dogs for Babesia spp is becoming increasingly important in the United States. 相似文献

The aim of this study was to determine if the use of auditory stimulation during early development stages of young puppies, using a variety of sounds such as music, radio talk shows, and ambient noise, that included car noises, sirens, and gunshots, could affect the results of early puppy testing of future police working dogs. Sixty-seven puppies at 7 weeks of age were submitted to a 9-situation test and their results analyzed. The sample comprised 34 males and 33 females, from 4 different breeds/crosses (27 German Shepherd Dog, 19 Belgian Malinois Shepherd Dog, 7 Dutch Shepherd Dog, and 14 animals of a cross of German Shepherd Dog with Belgian Malinois Shepherd Dog), representing 12 litters. Puppies were divided in 2 groups, G1 (n?=?46) and G2 (n?=?21), with G1 being submitted only to the standard socialization protocol in use in the Grupo de Intervenção Cinotécnico while puppies in G2, beside the standard socialization protocol, were also presented with auditory stimulation throughout the day, particularly during playtime and meal time. Significant differences were observed in some situations between groups, with puppies in G1 achieving better scores on this specific test, which aims to access a puppy's level of interaction with humans, reaction to manipulations, and reaction to different environmental stimulus. No differences were found between sexes but some differences between breeds were found, suggesting familial effects on noise reaction. Further studies, involving a greater number of puppies and litters, and that would also include noise exposure quantification, behavioral, and physiological assays are required to confirm these findings. It will also be of interest to evaluate if the results obtained as a young puppy have any connection with future adult performance. 相似文献

A 3-year-old female German Shepherd Dog was evaluated for progressive mental obtundation and vestibular signs. Central nervous system cryptococcosis was diagnosed on the basis of growth of Cryptococcus neoformans in fungal culture of CSF, as well as detection of the organism in CSF via microscopy. Cryptococcal capsular latex antigen agglutination titer was 1:262,144 in CSF and 1:1,048,576 in serum samples. Imaging with magnetic resonance augmented diagnosis. The dog improved after long-term treatment with fluconazole. Fluconazole is useful in the treatment of CNS cryptococcosis, because it attains high concentration in the CNS. Long-term therapy is often required for resolution of clinical signs, and affected animals may require long-term follow-up with periodic evaluation of CSF via fungal culture and latex agglutination tests. Monitoring serum latex agglutination test results may provide a safe, less invasive means of monitoring response to treatment. 相似文献

Primary hereditary cataract is recorded and described in the German Shepherd Dog in the United Kingdom. The cataract is not congenital, it is bilateral and progressive to a certain point and is unassociated with any other ocular abnormality. It is due to an autosomal, recessive gene. The cataract is compared to that described by von Hippel in Germany in 1930 which was congenital and non-progressive and due to a dominant gene. The two types of cataract are therefore dissimilar. 相似文献

The Fusarium species are a group of saprophytic fungal organisms that are occasionally the cause of opportunistic infections in humans and animals. Central nervous system disease associated with a Fusarium species is most commonly described in horse, resulting in equine leukoencephalomalacia. This report describes a 2-year-old, spayed, female German Shepherd Dog with meningoencephalitis secondary to infection with Fusarium spp. Meningoencephalitis in dogs secondary to a species of Fusarium has not been previously reported. The diagnosis was made based on the histopathologic examination of brain tissues postmortem and special immunohistochemical stains specific for Fusarium solani. The clinical signs in this dog were indicative of multifocal brain disease and included seizures and a paradoxical vestibular syndrome. The clinical findings, diagnostic and histopathologic test results, and the comparative characterizations of other disseminated fungal diseases, especially aspergillosis, are described. 相似文献

The population of U.S. Department of Defense military working dogs provides an opportunity to study the lifetime occurrence of neoplasia in 2 breeds of dogs—the German Shepherd Dog and the Belgian Malinois. Medical records were reviewed for all dogs that died or were euthanized in 1992 (135 German Shepherd Dogs and 106 Belgian Malinois). Histologically confirmed neoplasms were recorded. More than 30% of both breeds (41 German Shepherd Dogs and 33 Belgian Malinois) developed at least 1 primary neoplasm during their lives, with 10% developing more than 1 neoplasm. Nearly 57% of the neoplasms were benign, and approximately 43% were malignant. German Shepherd Dogs lived 9.7 years, on average, and Belgian Malinois lived 7.9 years, on average. Of the dogs that developed any neoplasm, Belgian Malinois had a mean age at 1st diagnosis that was 1.1 years younger and a mean age at 1st diagnosis of malignancy that was 1.7 years younger than those in German Shepherd Dogs. The risk of a malignancy being the cause of death or euthanasia of a Belgian Malinois was 4.21 times the risk in German Shepherd Dogs (95% CI: 1.32, 13.47). Seminoma was the malignancy that occurred most frequently. Hemangioma was the benign neoplasm that occurred most frequently. Veterinarians identified masses clinically at equal rates in both groups. 相似文献

Gross and microanatomic features which may predispose the German Shepherd Dog to perianal fistulae formation were studied in 2 groups of clinically healthy dogs: a predisposed group (German Shepherd Dogs) and a control group comprising breeds not ordinarily affected by perianal fistulae. The dimensions of the anal crypts (depth, base width, and length), measured and compared statistically between samples, identified no significant variation between groups (P greater than 0.05). Major tissue components of the anal canal were measured microscopically and were similarly evaluated: epithelial height in each zone, thickness of the lamina propria in each zone, thickness of the internal and external anal sphincter muscles, and density of the circumanal, sebaceous, and apocrine sweat glands. The only significant finding was an increase in density of apocrine sweat glands in the zona cutanea in the pre-disposed dog group. In a semiquantitative analysis of the inflammatory responses frequently seen in the anal glands, more mature fibroplasia was seen in the German Shepherd Dogs, indicating that inflammation was more longstanding in this group. 相似文献

For 7 breeds of bitches (Toy Poodle, Cocker Spaniel, Basset Hound, Boston Terrier, German Shepherd Dog, Pekingese, and Beagle), estrous activity occurred in all seasons. Differences in seasonal incidence of estrus were not statistically significant when compared within the total group or within and between breeds. The German Shepherd Dog breed had the shortest interestrous interval (149 +/- 28.5 days), which was significantly different from that of the other breeds. Means interestrous interval in parous Beagle bitches was not significantly different from that in nonparous Beagle bitches. In Beagle bitches, the mean interval between fertile estrous periods was not significantly different from the mean interval between nonfertile estrous periods. 相似文献

A lysosomal storage disease was diagnosed in 2 Australian Cattle Dog siblings, using light and electron microscopic evaluation. Both dogs developed clinical signs of disease at about 1 year of age. Vision and motor function deteriorated over several months; by 2 years of age, the dogs were blind and had progressive ataxia. Cytoplasmic inclusions with ultrastructural patterns characteristic of ceroid lipofuscin were observed in most neurons examined and in the cells of several other parenchymatous tissues. Biochemical studies, including determination of lysosomal enzyme activities, excluded several other lysosomal storage diseases. In these dogs, the clinical and pathologic features of the disease were similar to those of the juvenile subtype of ceroid lipofuscinosis (Batten disease) in human beings. 相似文献

A 3 1/2-year-old intact male German Shepherd Dog was admitted with a history of protracted haemorrhagic diarrhoea and tenesmus. Clinical evaluation revealed thickening of the rectal mucosa and presence of fresh blood and mucus in the faeces. Severe mucosal granularity and multiple nodules, in addition to a rectal stricture 7 to 9 cm from the anus, were found on colonoscopy. Histopathological evaluation of biopsy specimens identified organisms with morphologic features compatible with those reported for Prototheca spp. Although surgical excision of the rectal stricture was performed and ketoconazole treatment was instituted postoperatively, the dog's clinical condition deteriorated and euthanasia was performed 4 months later. 相似文献

Canine Hip Dysplasia (CHD) is still a significant health problem among dogs of so called predisposed breeds where this disease is revealed even among 30% individuals of the whole population. The present results were obtained by two clinics and deal with CHD occurrence among the most frequently and predisposed breeds in Olsztyn and Siemianowice Slaskie/Upper Silesia, Poland. Radiographs of hip joints were described using Riser's method. Altogether 2279 dog were examined including 2113 animals which were analysed. The German Shepherd Dog was the prevalent breed found in both clinics, but CHD was not common in this breed. In the Olsztyn Clinic, the most numerous group affected by CHD was Neapolitan Mastiff (60%), while in the Siemianowice Slaskie Clinic, dysplasia dominated in Bernese Mountain Dog (46%). 相似文献

An enlarged nodular mass, assumed to be the prostate gland because of location and consistency, was palpated in the pelvic region of a 10-year-old German Shepherd Dog. Castration was performed as a therapeutic procedure after an estrogenic hormone failed to reduce the size of the mass. A tumor identified histologically as a seminoma was in the right testicle. The dog died 1 month after castration, and generalized metastatic neoplasia was observed at necropsy. The mass that involved the neck of the bladder and the metastases were identified as leiomyosarcoma. 相似文献

Osteosarcoma was diagnosed in a 7-month-old female German Shepherd Dog with hind limb paresis. Radiography revealed a circumscribed calcified mass in the dorsal vertebral lamina at T13-L1 resulting in extradural compression of the spinal cord. Surgical excision of the mass resulted in gradual return to normal neurologic function. Four weeks after surgery, the dog became severely atactic after rolling onto its back. A chip fracture of T13 was identified, and the dog was euthanatized at the owners' request. 相似文献

A four-month-old German Shepherd Dog (GSD) was admitted with bilateral non-weight bearing hindlimb lameness and pyrexia. A diagnosis of bilateral distal femoral fractures secondary to metaphyseal osteopathy was made on the basis of clinical signs, radiography and biopsy. The dog returned to normal function following conservative management. As far as the authors are aware there are no previous reports of pathological fractures secondary to this condition. 相似文献

From 1974 through 1984, the Orthopedic Foundation for Animals evaluated 143,218 radiographic submissions representing 151 breeds of dogs. All breeds from which there were 35 or more evaluations had some frequency of dysplasia. Seventy breeds, each with over 100 submissions, were tabulated and ranked according to frequency of hip dysplasia. Frequency of dysplasia varied from 0.6% in the Borzoi to 46.9% in the Saint Bernard. These data were compared with data obtained earlier (1966 to 1973) on evaluations in 38 breeds for changes in frequency. There was significant (P less than 0.05) reduction in frequency of dysplasia in 27 breeds, a significant (P less than 0.05) increase in frequency in only 1 breed (German Shorthaired Pointer), and no significant change in frequency in 10 breeds. The median significant decrease was 22.4%, and the range was from 3.1% in the Chesapeake Bay Retriever to 48.7% in the Keeshond. The reduction in frequency of hip dysplasia demonstrated the value of a control program. There were 5 breeds with a significant (P less than 0.05) decrease in frequency of dysplasia that had over 5,000 evaluations from 1974 to 1984. The decreases in frequency were independent of changes in American Kennel Club registrations for these breeds (a dramatic decline in registrations for the German Shepherd Dog and Old English Sheepdog, and a dramatic increase for the Rottweiler, Golden Retriever, and Labrador Retriever). Frequency regressed linearly in the German Shepherd Dog and Old English Sheepdog, but regressed nonlinearly in the other 3 breeds. The percentage reduction in frequency from the base frequency (1966 to 1973) for these breeds was 17.5% for the German Shepherd Dog, 23.1% for the Old English Sheepdog, 9.1% for the Rottweiler, 10.1% for the Golden Retriever, and 6.8% for the Labrador Retriever. 相似文献

Ganglioside storage diseases are inherited defects of lysosomal hydrolases that result in intralysosomal accumulation of gangliosides and other complex metabolites. Gangliosidoses occur in man, cats, cattle, dogs and swine. In all species, these diseases are characterized clinically by relentlessly progressive neurological deterioration. Lysosomal hypertrophy with characteristic ultrastructural inclusions occur in neurons, endothelial and other cells. Definitive diagnosis requires biochemical identification of the storage product and enzyme deficiency. Gangliosidoses in animals are important models of human lysosomal diseases and may be a significant complication in the maintenance of certain purebred stocks of domestic animals. 相似文献
