A cat with multiple subcutaneous nodules suggesting a soft tissue sarcoma by physical and computed tomographic examination was diagnosed as being affected by subcutaneous filariosis based on cytologic and ultrasonographic assessments. Nodules were surgically removed and extracted nematodes were identified by PCR as Dirofilaria repens. Furthermore, DNA of Dipetalonema dracunculoides (syn. Acantocheilonema dracunculoides) was detected by PCR, with no evidence of circulating microfilariae. To the best of the authors' knowledge, this represents the first report describing adults of D repens in multiple subcutaneous nodules in a cat. Cytopathologic examination allowed characterization of the parasitic nature of the nodules. Veterinary practitioners should be aware of the possible nodular presentation of D repens in cats and should include D repens in the differential diagnosis of subcutaneous neoformations in the cat.  相似文献   

Pulmonary Angiomatosis and Hemangioma in Common Dolphins (Delphinus delphis) Stranded in Canary Islands     

Díaz-Delgado J  Arbelo M  Sacchini S  Quesada-Canales O  Andrada M  Rivero M  Fernández A 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2012,74(8):1063-1066

Vascular tumors and disorders, like angiomatosis, are rarely described in cetacean species. A retrospective histological study was carried out on lung samples from 35 common dolphins (Delphinus delphis) stranded in the Canary Islands coasts looking for morphological vascular changes and likely related causes. Twenty-five out of thirty-five (71%) common dolphins showed focal or multifocal angiomatosis-like lesions. A high association between this type of vascular proliferation and parasitic infestation was observed. In addition, a single pulmonary cavernous hemangioma not previously reported in common dolphins is presented.  相似文献   

Paraneoplastic hypereosinophilia in a dog with intestinal T-cell lymphoma     

Marchetti V  Benetti C  Citi S  Taccini V 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2005,34(3):259-263

A 9-year-old, intact male Doberman Pinscher was examined because of anorexia and weakness. Results of a CBC showed severe, microcytic, hypochromic anemia with mild eosinophilia (2944 cells/microL, reference interval 100-1250/microL) and thrombocytosis. Hypoferremia, hypoferritinemia, and a positive fecal occult blood test supported a diagnosis of iron deficiency anemia secondary to chronic intestinal hemorrhage. Abdominal ultrasound evaluation showed a thickened small intestinal loop, of which representative specimens were obtained during exploratory laparotomy. Histologically, the intestinal wall was infiltrated by a neoplastic population of large, round, lymphoid cells with vesicular chromatin, 1 or more prominent nucleoli, and a high number of mitotic figures. The cells were closely admixed with mature eosinophils, but were negative for metachromatic granules with toluidine blue. Immunohistochemically, tumor cells were positive for CD3, and negative for CD21, Pan B, and CD79a. A diagnosis of intestinal T-cell lymphoma was made. Chemotherapy was begun, with 30 mg/m;2 of doxorubicin administered intravenously every 3 weeks. Eosinophil concentration was 880/microL 2 weeks after surgery (on day 15 after presentation) but increased markedly to 62,914/microL on day 30, 62,400/microL on day 37, and 39,444/microL on day 58 after presentation. An association between hypereosinophilia and T-cell lymphoma is well established in human patients, in whom production of IL-5 by neoplastic T cells has been demonstrated. Hypereosinophilia has been reported only rarely with intestinal lymphoma in cats and horses, and with T-cell lymphoma in dogs.  相似文献   

Haemangiopericytoma: histological spectrum, immunohistochemical characterization and prognosis     

Mazzei M  Millanta F  Citi S  Lorenzi D  Poli A 《Veterinary dermatology》2002,13(1):15-21

Canine haemangiopericytoma (CHP) is a vascular neoplasm thought to be derived from pericytes. The histological pattern and immunohistochemical profile were studied in 31 CHPs. Twenty-three subjects were followed for 2 years to evaluate the correlation among tumour location, histotype, immunostaining and outcome of the disease. Of the 31 CHPs examined, 20 exhibited a perivascular whorled pattern, 8 were storiform and 3 were epithelioid. All tumours were positive for vimentin and negative for cytokeratin, factor VIII-related antigen, glial fibrillary acidic protein and S-100 protein. Seventeen CHPs were positive for actin and nine co-expressed desmin. Six CHPs were also positive for CD34 antigen. The panel of immunohistochemical markers used confirmed the vascular lineage of CHP and aided in the exclusion of other mesenchymal tumours. Of the 23 dogs submitted to follow-up, 6 had recurrence or metastases of the primary tumour. The epithelioid pattern or a noncutaneous location were associated with a poorer prognosis.  相似文献

Foal-Heat Diarrhea Is Not Caused by the Presence of Yeasts in Gastrointestinal Tract of Foals     

Micaela Sgorbini  Simona Nardoni  Francesca Mancianti  Alessandra RotaMichele Corazza  DVM 《Journal of Equine Veterinary Science》2008

The aim of this study was to evaluate whether a normal yeast flora is present in the intestine of healthy foals and whether establishing yeast flora or yeast overgrowth might be associated with foal-heat diarrhea. Among the sampled foals, 49% showed foal-heat diarrhea and 28.3% were positive for yeasts. Candida famata was isolated 9 times; Geotrichum sp., 6; Saccharomyces cerevisiae, 5; Cryptococcus laurentii, 4; Rhodotorula sp., 3; Zygosaccharomyces sp., 2; and Candida colliculosa, Candida globosa, and Candida pelliculosa 1 time, respectively. The colony-forming unit ranged from 1 to 10 in all positive cultures. Fifteen of 92 (16.3%) foals with heat diarrhea and 11 of 92 (11.9%) asymptomatic animals yielded positive samples for yeasts. None of the animals shed the same yeast more than 2 times consecutively, and yeasts were found in pure or mixed culture. Equine gastrointestinal tract did not appear to be colonized by yeasts during the first 15 days of life, and yeasts are not involved in foal-heat diarrhea.  相似文献

Characterization of cell wall associated proteins of a Staphylococcus aureus isolated from bovine mastitis case by a proteomic approach   总被引：1，自引：0，他引：1

Staphylococcus aureus causes different pathologies in humans and animals. In particular, it is involved in intramammary infections in cows, causing economic losses and milk-safety problems. Although it is well-known that surface components (proteins and capsular polysaccharides) and exotoxins are virulence factors involved in the pathogenesis of bovine mastitis, less is known about the precise biochemical identity of such molecules. Therefore, mapping of surface proteins using specific disease- and environment-isolates provides a benchmark for strain comparison of pathogens with different pathogenic characteristics and antibiotic resistance mechanism and can aid in defining specific vaccine and therapeutic targets. In this study, we used a proteomic approach on protein extracts of lysostaphin-treated S. aureus in isotonic conditions, to produce a reproducible and well resolved 2-D electrophoresis (2-DE) reference map of surface associated proteins of isolated S. aureus from a case of bovine mastitis. The most abundant protein components were identified by Matrix assisted laser desorption ionisation-time of flight (MALDI-TOF) mass spectrometry.  相似文献   

Prevalence of cryptosporidian infection in cats in Turin and analysis of risk factors     

Rambozzi L  Menzano A  Mannelli A  Romano S  Isaia MC 《Journal of Feline Medicine and Surgery》2007,9(5):392-396

An epidemiological study was carried out to identify factors associated with the risk of cryptosporidian infection in cats. Faecal samples from 200 domestic cats were collected in the small animal clinic at the Faculty of Veterinary Medicine in Turin (north-west Italy). The faecal samples were analysed for the presence of Cryptosporidium species oocysts using a centrifugation concentration floatation method. For each cat, age, sex, breed, indoor/outdoor status, diet, diarrhoea and presence of other enteric parasites were analysed for association with Cryptosporidium species infection. Cryptosporidia oocysts were identified in 49 cats (24.5%) aged from 2 months to 18 years. Statistical analysis revealed that four variables are significantly associated with an increased risk of infection: less than 1 year of age (chi(2)=6.5, P=0.01), feeding home-cooked diet (chi(2)=6.92, P<0.01), presence of diarrhoea (chi(2)=4.34, P<0.037), and presence of other enteric parasites (chi(2)=10.31, P<0.01). No statistical differences were found for sex (chi(2)=1.56, P=0.21), breed (chi(2)=0.78, P=0.38) and outdoor/indoor status (chi(2)=1.49, P=0.22). Cryptosporidium species was the parasite most frequently detected in the cats surveyed.  相似文献
