A 2-year-old Dachshund was presented for vomiting and diarrhea. Abdominal ultrasound revealed Dirofilaria immitis in the abdominal aorta and an avascular segment of small intestine. The dog was euthanized. Necropsy revealed D. immitis in the abdominal aorta and widespread necrotizing arteriolitis. This is a unique presentation of aberrant migration of D. immitis. 相似文献

A 2 yr old spayed female German shepherd presented with a chief complaint of acute onset paraparesis and weight loss. At presentation, the dog was pyrexic, nonambulatory, and had generalized muscle wasting. Neurolocalization was consistent with a thoracolumbar spinal cord lesion. An abdominal ultrasound was performed and revealed a focal dilation (4 cm) of the terminal aorta with evidence of blood stasis consistent with an aortic aneurysm. The dog was euthanized shortly after admission to the hospital and a post mortem examination was performed. Fungal organisms were identified in the aortic aneurysm as well as from the thoracic vertebrae, mesenteric lymph nodes, axillary lymph nodes, spleen, kidneys, liver, lungs, and heart. Although the morphology was consistent with Candida spp., immunohistochemistry and PCR could not definitively identify the causative organism. Mycotic aortic aneurysms are a rare finding in humans and have not been previously reported in the dog. To the authors' knowledge, this is the first known report of an aortic aneurysm associated with systemic fungal infection in a dog. 相似文献

In June 2014, a male stray dog was recovered at Ente Nazionale di Protezione Animali
(ENPA) kennel of Manfredonia, Apulia region, showing oral bleeding and physical
prostration. The dog fell in a water canal and was trapped. During the clinical
examination, a specimen of leech was revealed into its oral cavity. The parasite, probably
entered by drinking unfiltered and contaminated water, has been identified as an adult of
aquatic leech Limnatis nilotica. Leeches could overrun wide variety of
animals, and few reports about blood sucking leech infestations in mammals are available
in literature. This paper describes here the first oral hirudiniasis in a dog in Italy and
highlights the possibility of human nasopharyngeal leech-related infection in Apulia
region. 相似文献

A thoracic aortic aneurysm was diagnosed in a 6-month-old male Leonberg dog by use of radiography, transthoracic and transesophageal echocardiography, and magnetic resonance imaging. The aneurysm was associated with a twisted ascending aorta and dilatation of several other thoracic arteries (pulmonary trunk, brachiocephalic trunk, and left subclavian artery). Histologic examination of the aorta revealed cystic medial necrosis, with disruption of the elastic network, collagen fibers, and the muscle glycoprotein fibrillin-1. The dam and sire of the dog and 8 littermates were examined by use of transthoracic echocardiography. The sire and 1 male littermate also had an aneurysm of the ascending aorta. To the authors' knowledge, this is the first report of familial aortic aneurysm in dogs. 相似文献

An 8-year-old, spayed, female Shiba dog was presented to a referring veterinarian with a
complaint of chronic diarrhea and anorexia. Ultrasound and radiographs revealed an
irregular mass in the pelvic cavity. The mass and the affected section of colon were
surgically removed. Histopathological examination revealed multifocal coalescing
granulomas and effaced intestinal structures. Central necrotic debris surrounded by
multinucleated giant cells, lymphocytes, plasma cells and neutrophils was observed.
Numerous, irregularly branched hyphae with pale basophilic, thin walls and occasional
bulbous enlargements at the tips were present. Polymerase chain reaction identified
Basidiobolus ranarum, successfully confirming a definitive diagnosis of
basidiobolomycosis. To the best of our knowledge, this is the first report of intestinal
basidiobolomycosis in a dog. 相似文献

Dirofilaria repens infection was diagnosed in a dog that had been imported to Norway from Hungary three years previously. The dog was a four-year-old castrated male mixed-breed dog and presented for examination of two masses on the right thoracic wall. Fine needle sampling from the subcutaneous nodules and subsequent cytological examination revealed a high number of microfilariae and a pyogranulomatous inflammation. At re-examination approximately 3 weeks later, both masses had apparently disappeared spontaneously, based on both inspection and palpation. However, examination of peripheral blood by a modified Knott’s test revealed a high number of unsheathed microfilariae with mean length of 360 μm and mean width of 6-7 μm, often with the classic umbrella handle appearance of D. repens. Polymerase chain reaction and sequencing confirmed the D. repens diagnosis. Subcutaneous dirofilariosis caused by D. repens is probably the most common cause of human zoonotic dirofilariosis in Europe, but currently is rarely encountered in northern countries such as Norway. However, travelling, import and relocation of dogs have increased, and thus the geographical range of these parasites is likely to increase from traditionally endemic southern regions. Increasing numbers of autochthonous cases of D. repens infections in dogs have been reported in eastern and central Europe. Although infection with D. repens often induces only mild signs or subclinical infections in dogs, they nevertheless represent a reservoir for zoonotic transmission and thus a public health concern, and, in addition, due to the long prepatent period and the high frequency of subclinical infections or infections with unspecific clinical signs, could easily be missed. Lack of experience and expectation of these parasites may mean that infection is underdiagnosed in veterinary clinics in northern countries. Also, predicted climate changes suggest that conditions in some countries where this infection is currently not endemic are likely to become more suitable for development in the intermediate host, and thus the establishment of the infection in new areas. 相似文献

An eleven-year-old Chinese Crested Powder Puff dog presented with polydipsia/polyuria, inappetence, diarrhea and vomiting underwent an ultrasound-guided percutaneous liver biopsy. Two days post-biopsy the clinical condition of the dog acutely deteriorated with fever, dyspnea, ataxia and subcutaneous emphysema. Radiographs and ultrasound showed focal severe hepatic emphysema in the region of the previous liver biopsy. Post-mortem examination revealed chronic hepatitis with dissecting fibrosis, acute hepatitis with hemorrhage and in the hindlimb musculature extensive hemorrhage and necrosis. Pure cultures of the gas producing bacteria Clostridium perfringens were isolated in samples from the hind limb musculature. We propose that the hepatic emphysema in the region of the biopsy site was a result of a clostridial infection. 相似文献

A Pomeranian dog, 1 year- and 8 month-old neutered female, was presented with persistent
respiratory distress and recurrent generalized demodicosis. Physical examination revealed
cyanosis, rough respiratory sounds, multifocal alopecia and dermal erosions on the dorsal
side of the forelimbs, perineal area and skin around the eyes. A severe diffuse
interstitial lung pattern was observed on thoracic radiographs. The blood examination
revealed neutrophilia and hypoglobulinemia. Serum immunoglobulin concentrations of IgG and
IgA were low. Histopathological examination revealed severe diffuse interstitial pneumonia
with Pneumocystis carinii infection. Severe lymphoid depletion was
observed in the spleen and other organs with lymphoid follicles consisted mainly of
CD3-positive T cells and few cells of B-cell lineage. B-cell hypoplasia with subsequent
antibody deficiency was suspected. 相似文献

: Infection with Angiostrongylus vasorum was diagnosed at necropsy on a dog that died from acute pulmonary haemorrhage, and on recovery of L1 larvae by Baermann examination of faeces from two dogs, one of which had abdominal pain and retroperitoneal haemorrhage, while the other had right-sided heart failure due to cor pulmonale. The presenting signs included syncope (one dog), exercise intolerance (two dogs), cough (two dogs), abdominal pain (one dog) and depression (one dog). One-stage prothrombin time and activated partial thromboplastin time were prolonged in two dogs, buccal mucosal bleeding time was prolonged in one dog and globulin was elevated in all three dogs. Two dogs were treated with fenbendazole and recovered. 相似文献

Thrombosis is a potential complication of hyperadrenocorticism (HAC) in dogs. An 8-year-old male Beagle diagnosed with pituitary-dependent HAC had complicated with thrombosis in the caudal vena cava and abdominal aorta, which was treated by hypophysectomy and antithrombotic therapy. After hypophysectomy, hypercortisolemia disappeared and the general condition was also significantly improved. Ultrasonography after hypophysectomy revealed that the thrombus remained in the abdominal aorta, but the thrombus in the caudal vena cava had disappeared. However 692 days after the hypophysectomy, the dog had an acute onset of dyspnea and died. Postmortem examination revealed the presence of thrombi in the abdominal aorta and the pulmonary artery. Observations from this case show that HAC dogs must be attention to thrombosis. 相似文献

Canine babesiosis caused by different Babesia species is a protozoal tick-borne disease with worldwide distribution and global significance. Historically, Babesia infection in dogs was identified based on the morphologic appearance of the parasite in the erythrocyte. All large forms of Babesia were designated Babesia canis, whereas all small forms of Babesia were considered to be Babesia gibsoni. However, the development of molecular methods has demonstrated that other Babesia species such as Babesia conradae, Babesia microti like piroplasm, Theileria spp. and a yet unnamed large form Babesia spp. infect dogs and cause distinct diseases. Babesia rossi, B. canis and Babesia vogeli previously considered as subspecies are identical morphologically but differ in the severity of clinical manifestations which they induce, their tick vectors, genetic characteristics, and geographic distributions, and are therefore currently considered separate species. The geographic distribution of the causative agent and thus the occurrence of babesiosis are largely dependent on the habitat of relevant tick vector species, with the exception of B. gibsoni where evidence for dog to dog transmission indicates that infection can be transmitted among fighting dog breeds independently of the limitations of vector tick infestation. Knowledge of the prevalence and clinicopathological aspects of Babesia species infecting dogs around the world is of epidemiologic and medical interest. Babesiosis in domestic cats is less common and has mostly been reported from South Africa where infection is mainly due to Babesia felis, a small Babesia that causes anemia and icterus. In addition, Babesia cati was reported from India and sporadic cases of B. canis infection in domestic cats have been reported in Europe, B. canis presentii in Israel and B. vogeli in Thailand. Babesiosis caused by large Babesia spp. is commonly treated with imidocarb dipropionate with good clinical response while small Babesia spp. are more resistant to anti-babesial therapy. Clinical and parasitological cure are often not achieved in the treatment of small Babesia species infections and clinical relapses are frequent. The spectrum of Babesia pathogens that infect dogs and cats is gradually being elucidated with the aid of molecular techniques and meticulous clinical investigation. Accurate detection and species recognition are important for the selection of the correct therapy and prediction of the course of disease. 相似文献

This study describes an occurrence of pink morning glory (Ipomoea
carnea) intoxication in goats in northern Argentina. The clinical signs
displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the
neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The
clinico-pathologic examination revealed that the affected animals were anemic and their
serum level of aspartate aminotransferase was significantly increased. Cytoplasmic
vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological
examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA
(Triticum vulgaris), sWGA (succinylated T. vulgaris)
and LCA (Lens culinaris). Although I. carnea is common
in tropical regions, this is the first report of spontaneous poisoning in goats in
Argentina. 相似文献

Seven laboratory mammal and
bird species were orally inoculated with 200–1,000 encysted Metagonimus
hakubaensis metacercariae that had been isolated from naturally infected
lampreys (Lethenteron reissneri) captured in Aomori Prefecture. At 8 and
15 days post-infection, adult flukes were recovered from all of the laboratory animals
tested, and therefore, hamster, rat, mouse, dog, cat, chicken and quail were considered as
final hosts of M. hakubaensis. Recovery rates of the fluke were higher in
dogs and hamsters than in cats, rats, mice, chickens and quails. The flukes recovered from
dogs and hamsters showed increased body length and higher fecundity than those recovered
from the other hosts. These results indicate that the suitability of dogs and hamsters for
M. hakubaensis infection is higher than that of the other laboratory
animals. 相似文献

A 13-year-old spayed mixed-breed dog was diagnosed with a gastrointestinal
stromal tumor (GIST) after histopathological examination of an abdominal mass. Five months
after surgical resection of the tumor, we detected the recurrence of GIST with multiple
disseminated abdominal lesions. A sequence analysis of cDNA obtained from a biopsy of the
recurrent tumors revealed a mutation within exon 9 of the c-kit gene
(1523A>T, Asn508Ile), which has been shown to cause ligand-independent
phosphorylation of the KIT protein in GISTs and canine mast cell tumors (MCTs). Upon
detection of the recurrent tumors, we initiated treatment with imatinib mesylate (10
mg/kg, q 24 hr). After 2 months, the dog achieved complete remission. Our findings
indicate that canine GIST, and possibly MCT, may be responsive to molecular-targeted
therapy. 相似文献

Otitis media of the left ear was diagnosed by video otoscopic examination in a 7-year-old, intact male Shih-tzu dog (weight, 5.1 kg), that also had three complex ceruminous adenomas and a Pseudomonas aeruginosa infection in the left ear canal. In such cases, total ear canal ablation is usually required. However, a complete cure was achieved in the present case without total ear canal ablation. The complex ceruminous adenomas were excised using a diode laser, and repeated cleansing of the tympanic cavity and ear canal was implemented using a video otoscope. As a result, the ear canal was closed in a U-form, and the otitis media was cured. 相似文献

Amplification of the 16S rRNA gene from a blood sample obtained from a dog in southeastern Brazil was used to confirm a naturally acquired Ehrlichia (E.) canis infection. Following isolation and culturing of the new bacterial strain called Uberlândia, partial sequences of the dsb and p28 genes were obtained. The dsb partial sequence of the novel strain was 100% similar to dsb gene sequences of E. canis obtained from different geographic areas around the world. Conversely, the p28 partial sequence for the E. canis Uberlândia strain differed at several nucleotides from other sequences available in GenBank. To confirm the antigenic profile of the Uberlândia strain, an indirect immunofluorescence assay against E. canis antigens was performed using dog sera collected from two different areas in Brazil (Uberlândia and São Paulo). The results suggest that both antigens were able to identify animals seropositive for E. canis in Brazil since these Brazilian strains appear to be highly conserved. 相似文献

A 9-year-old female mixed-breed dog presented with ascending flaccid tetraparesis, and a 5-year-old castrated male Poodle dog presented with ventroflexion of neck, dysphonia, and hindlimb weakness, which progressed to acute ascending tetraparesis. Both dogs were fed raw poultry for over 9 and 5 years, respectively. Blood examination and other test results were normal or unrelated to the present case. Fecal polymerase chain reaction analysis in the Poodle dog was positive for Clostridium perfringens and Campylobacter jejuni. Tetraparesis improved with supportive care in both dogs. Human IV immunoglobulin was only administered to the Poodle dog, which showed a shorter recovery (12 days compared to 34 days in the mixed-breed dog). Both dogs returned to normal conditions eventually. 相似文献

This report presents a new case of mucormycosis encountered in penguin characterized by morphological variation of hyphae and presence of sporangia with numerous sporangiospores. A 4.5-year-old Magellanic penguin (Spheniscus magellanicus) died after exhibiting anorexia, poor nutritional condition and dyspnea. Multiple nodular lesions were observed in the thoracic and abdominal regions. Histopathologically, hyphae of various sizes were seen in the lungs, air sac and nodular lesions. Myriad sporangiospores and several sporangia were observed in/around the bronchi or parabronchi. The very narrow and short hyphae in the nodules were not consistent with the characteristics of Mucorales. However, for most hyphae, including those in the nodules, sporangiospores and sporangia, immunohistochemistry revealed Mucorales-positive reactions. In addition, these fungi were identified as Rhizomucor pusillus by gene
analysis. 相似文献

A 14-year-old, mixed breed dog was presented with acute pain and paresis of the hindlimbs. Ultrasonography revealed an intraluminal mass and an abrupt halt of blood flow signal in the distal abdominal aorta. The mass had homogeneous hyperechoic echotexture compared with blood flow. Although clinical presentation suggested a thromboembolism and pituitary dependent hyperadrenocorticism was suspected as a predisposing cause based on adrenal function tests and ultrasonography, an aortic chondrosarcoma originating from the distal abdominal aorta was diagnosed with histologic examination. Primary aortic sarcoma is extremely rare, and extraskeletal chondrosarcoma is only reported in 2 cases previously. Aortic neoplasm should be included in differential diagnosis when an intraluminal aortic mass is observed on ultrasonography and acute paresis of hindlimbs is shown. 相似文献

A 12-yr-old female free-ranging Florida panther (Felis concolor coryi) was found dead in good flesh. The panther had a ruptured thoracoabdominal aneurysm and 0.5 L of unclotted blood in its thorax. Intimal plaques 6.0 x 3.0 x 3.0 cm and 4.0 x 3.0 x 1.0 cm were present in the thoracic and abdominal aorta extending below the bifurcation of the renal arteries. Histologic examination revealed necrohemorrhagic aortitis with a mixed inflammatory infiltrate of lymphocytes, macrophages, and neutrophils. Death was almost certainly due to exsanguination and hypovolemic shock secondary to the ruptured aneurysm, and the aortitis with the resultant aneurysm may have been secondary to an infectious or a toxic process. This is the first reported death of a free-ranging mammal from a ruptured aortic aneurysm. 相似文献
