Abstract
Background Budd-Chiari syndrome (BCS) is considered a rare condition in cats that is characterized by the obstruction of the hepatic venous outflow tract from the level of the small hepatic veins to the level of the termination of the inferior vena cava into the right atrium in the absence of cardiac or pericardial disease, or sinusoidal obstruction syndrome. Case description This report presents a 13-year-old cat with a two-week history of progressive lethargy, inappetence, weight loss, and abdominal distension. Findings/treatment and outcome The radiological study was consistent with pleural effusion, as well as alveolar and interstitial pulmonary patterns. Ultrasonography confirmed hepatic venin congestion and ascites. Abdominocentesis revealed a modified transudate. A computed tomography (CT) angiography showed a mass at the level of the caudal mediastinum that compressed the caudal vena cava (CVC). Mediastinal lymphoma was considered the most likely differential diagnosis. These findings were interpreted as Budd-Chiari-like syndrome (BCLS) secondary to a mediastinal mass although, unfortunately, no further diagnostic or treatment procedures were accepted by the owners. BCLS is a rare condition in cats, where most of the reported cases occurred as a result of obstruction of the caudal vena cava. In this report, BCLS was caused by a mass located in the caudal mediastinum oppressing the caudal vena cava. Conclusion This is the first report of BCLS in cats diagnosed by CT angiography, and it shows the value of this technique to define the origin and extent of the mass and to evaluate the presence or absence of metastatic lesions.

Abstract
We present a unique case of metastatic cholangiocarcinoma with concurrent abdominal cestodiasis in an African green monkey (Chlorocebus pygerythrus) that presented with respiratory insufficiency and abdominal discomfort. There were multiple white-grey masses in the liver and colonic serosa alongside intra-abdominal parasitic cysts. Histopathologically, the liver masses were composed of poorly-differentiated epithelial cells that formed densely cellular solid areas and trabeculae. The neoplastic cells were strongly immunopositive for CK7 but negative for Hep-Par1 antigen, which confirmed a diagnosis of cholangiocarcinoma. Interestingly, there was strong and diffuse neoexpression in the tumour of the cell cycle regulator 14-3-3σ, which is not constitutively expressed in normal liver. There was aberrantly strong expression of E-cadherin, a key cell-cell adhesion protein, in neoplastic cells with evidence of cytoplasmic internalization. This is the first immunohistochemical analysis of 14-3-3σ and E-cadherin in a liver neoplasm in an animal species and the use of these markers requires further investigation in animal liver neoplasms.

Abstract
In humans, apocrine gland tumours encompass a heterogeneous group of uncommon neoplasms with varied and unpredictable biological behaviour. They can be slow-growing lesions, recur after excision, produce lymph node metastasis in up to 50% of cases or lead to tumour-related death. We document a malignant scent adenocarcinoma in a wedge-capped capuchin monkey (Cebus olivaceus). Immunohistochemical labelling revealed complete absence of myoepithelial cells, a finding usually considered a hallmark of malignancy in humans; however, after a 2-year follow-up, the neoplasm had not recurred. This is the first detailed report of the pathology of a spontaneous scent (apocrine) gland adenocarcinoma in a non-human primate.

Abstract
BACKGROUND Paraneoplastic pemphigus is an autoimmune blistering skin disease associated with concurrent neoplasia that is rarely observed in veterinary medicine. CASE DESCRIPTION This case report presents a ten-year-old female Labrador Retriever dog with generalized seborrhea and alopecic, crusting and ulcerative lesions in the periocular and perioral regions, the lips and the groins. FINDINGS/TREATMENT AND OUTCOME Hematology analysis showed a marked increase in the number of lymphocytes, while the rest of the values were normal. Skin biopsies were collected and the histological findings were consistent with pemphigus in association with an epitheliotropic lymphoma. Immunohistochemical analysis was performed. There was deposition of immunoglobulin G (IgG) in the basement membrane and in the intercellular space that corresponded with an immunostaining pattern characteristic of pemphigus erythematosus (PE). The lymphoma was positive to CD3 cells and was classified as a T-cell epitheliotropic lymphoma. CONCLUSION To our knowledge, this is the first case of PE and cutaneous lymphoma coexisting in a dog, expanding the list of associations between immune-mediated diseases and cancer in dogs, and providing support to the eventual connection between autoimmunity and neoplasia in this species.

Abstract
The objective of this study was to evaluate the effects of replacing rye-grass (Lolium spp.) hay with banana (Musa acuminata L.) by-products on feed intake, average daily gain (ADG), and feed conversion rate (FCR) in Pelibuey (hair sheep breed) lambs. The lambs (n = 22; initial BW = 14.8 ± 2.5 kg) were individually housed and fed on two different types of diet for 58 days: the first group (experimental diet) received as forage a mixture of fresh banana by-products composed of leaves and pseudostem. The second group received commercial rye-grass hay (conventional diet) as a fiber source. Both groups received a supplementary commercial concentrate food. The total daily forage intake and FCR were lower (P < 0.001) in animals fed on the conventional diet (rye-grass hay) than animals fed on the experimental diet (banana by-products). However, there were no significant differences in total dry matter intake, total digestible energy intake, total body weight gain, and ADG between the two groups. The results obtained in this study suggest that banana by-products could be used as alternative forage for Pelibuey lambs raised in subtropical conditions.

Abstract
The microanatomy of the intestinal epithelium in the Chinese soft-shelled turtle (CST) was studied by light and transmission electron microscopy (TEM). The small intestinal epithelium (SIE) was single layered or pseudostratified. The enterocytes contained mitochondria or mitochondria and lipid droplets. The enterocytes were arranged tightly in the apical parts of epithelium and connected by desmosomes and interdigitations. The large intestinal epithelium (LIE) was pseudostratified and the enterocytes did not contain lipid droplets. Enterocytes were arranged compactly in the apical part, forming spaces in the middle and basal parts of epithelium. Numerous mucous cells were scattered in the epithelium and there were intraepithelial lymphocytes (IELs) with their pseudopodia extended into the intestinal lumen. This study provides detailed features of intestinal epithelium in the Pelodiscus sinensis that could be related to function. In addition, these findings are discussed in relation to other vertebrates.

Abstract
The aim of this study was to describe the normal magnetic resonance angiography (MRA) of the heart and associated vessels in a mature female cat using a 1.5-Tesla magnet. Non-contrast enhanced MRA was performed using a three-dimensional time of flight (TOF) sequence in parasagittal and dorsal aspects. Relevant cardiac and vascular structures were labelled on three-dimensional Time of flight images. Time of flight imaging showed details of the heart cavities and vessels lumen due to the high signal intensity of fast-flowing blood compared with bones, muscles, and lungs, which appeared with low signal intensity. Three-dimensional TOF sequences provided adequate anatomical details of the heart and good differentiation of the vascular structures that could be used for interpretation of cardiac images and to assist in future MRA studies.

Abstract
A study of the lesions of beaked whales (BWs) in a recent mass stranding in the Canary Islands following naval exercises provides a possible explanation of the relationship between anthropogenic, acoustic (sonar) activities and the stranding and death of marine mammals. Fourteen BWs were stranded in the Canary Islands close to the site of an international naval exercise (Neo-Tapon 2002) held on 24 September 2002. Strandings began about 4 hours after the onset of midfrequency sonar activity. Eight Cuvier's BWs (Ziphius cavirostris), one Blainville's BW (Mesoplodon densirostris), and one Gervais' BW (Mesoplodon europaeus) were examined postmortem and studied histopathologically. No inflammatory or neoplastic processes were noted, and no pathogens were identified. Macroscopically, whales had severe, diffuse congestion and hemorrhage, especially around the acoustic jaw fat, ears, brain, and kidneys. Gas bubble-associated lesions and fat embolism were observed in the vessels and parenchyma of vital organs. In vivo bubble formation associated with sonar exposure that may have been exacerbated by modified diving behavior caused nitrogen supersaturation above a threshold value normally tolerated by the tissues (as occurs in decompression sickness). Alternatively, the effect that sonar has on tissues that have been supersaturated with nitrogen gas could be such that it lowers the threshold for the expansion of in vivo bubble precursors (gas nuclei). Exclusively or in combination, these mechanisms may enhance and maintain bubble growth or initiate embolism. Severely injured whales died or became stranded and died due to cardiovascular collapse during beaching. The present study demonstrates a new pathologic entity in cetaceans. The syndrome is apparently induced by exposure to mid-frequency sonar signals and particularly affects deep, long-duration, repetitive-diving species like BWs.

Abstract
This is the first work that applies immunohistochemistry in the characterisation of the inflammatory infiltrate of verminous bronchopneumonia associated with lungworm parasites in stranded dolphins. Samples from three different species (Stenella coerulealba, Stenella frontalis and Delphinus delphis) stranded in the Canary Islands were used. The most common findings found in these animals varied from bronchitis to verminous bronchopneumonia with different degree of severity. The immunohistochemical study showed variable expressions of Lysozyme, MHC-II, iNOS and IgG. The main population presenting in the inflammatory infiltrates were CD3(+) lymphocytes. However, moderate number of Foxp3(+) lymphocytes was found in lymph nodes even though no Foxp3(+) cells were found in lung lesions in any of the samples analysed. This study revealed that lung lesions showed a chronic inflammatory infiltrate mainly composed by lymphocytes CD3(+). Deeper studies are needed in order to provide a more complete scope about the infiltrates involved in these types of lesions.

Abstract
Biliary cirrhosis produced by Campula spp. is described in 1 striped dolphin Stenella coeruleoalba and 4 harbour porpoises Phocoena phocoena. The hepatic lesions consisted of severe proliferation of fibrous connective tissue with loss of the lobular pattern, nodular regeneration of the hepatic tissue, bile duct hyperplasia and severe inflammatory infiltrate composed of eosinophils, macrophages, lymphocytes and plasma cells. These lesions were associated with severe infestation by Campula spp. Although inflammatory and degenerative hepatic lesions are frequently found in stranded dolphins, biliary cirrhosis has not been previously reported in cetaceans. Massive infestation by these parasites should be included as a cause of hepatic failure resulting in stranding of marine mammals.

Abstract
This paper describes the immunophenotype of cellular inflammatory infiltrates in chronic cholangitis in six common dolphins (Delphinus delphis), four striped dolphins (Stenella coeruleoalba), three Atlantic spotted dolphins (Stenella frontalis) and one pygmy sperm whale (Kogia Breviceps) found stranded along the coasts of the Canary Islands (Spain). A panel of 5 antibodies previously tested in dolphins (anti-CD3, -IgG, -MHC class II, -S100 protein and -lysozyme) were used. The present work also reports cross reactivity with dolphin antigens of two antibodies not used to date in dolphins (anti-mouse iNOS and anti-mouse Foxp3). The most common type of cholangitis found was chronic granulomatous cholangitis, associated with the presence of the parasite Campula spp., or its eggs in bile ducts. The cellular composition of the hepatic inflammatory infiltrate associated to chronic parasitic cholangitis was closely similar to that found in the cortex of control lymph nodes, including the presence of S100(+) and MHC class II(+) dendritic-like cells in lymphoid follicles and interfollicular areas. Only occasional macrophages expressed iNOS, whereas Foxp3(+) lymphocytes were not found in any of the lesions described in the different types of cholangitis.

Abstract
The expression of iNOS by macrophages in 33 dogs suffering from spontaneous leishmaniasis was analysed by immunohistochemistry in skin, liver and lymph nodes. A correlation study between the number of macrophages expressing iNOS and the number of macrophages containing leishmania amastigotes was carried out. Formalin-fixed paraffin-embedded tissue sections from the skin (28 cases), popliteal lymph nodes (8 cases) and liver (3 cases) of dogs of different age, sex and breed suffering from leishmaniasis were included in the study. Dogs were referred as positive for Leishmania spp by serology and the diagnosis was confirmed by demonstration of leishmania amastigotes within macrophages by histopathology. Tissue samples of skin (3 cases), popliteal lymph nodes (5 cases) and liver (3 cases) from dogs seronegative for leishmaniasis with no histopathological changes were included in the study as controls. The immunohistochemical study revealed that macrophages containing a high number of leishmania did not express iNOS. Correlation between the number of macrophages expressing iNOS and the number of macrophages containing leishmania amastigotes was assessed using the Spearman test. High expression of iNOS in macrophages was related with low number of leishmania amastigotes in macrophages in all cases (r=-0.47, p=0.002). These results suggest that iNOS expression by macrophages plays an important role during the control of Leishmania infection in dogs.

Abstract
This paper describes the gross, histopathological and immunohistochemical characteristics of gastrointestinal lesions and regional lymph nodes of six common dolphins (Delphinus delphis), 11 striped dolphins (Stenella coeruleoalba) and six Atlantic spotted dolphins (Stenella frontalis) found stranded along the coasts of the Canary Islands. The most common lesion was chronic granulomatous gastritis of the glandular stomach, associated with the parasite Pholeter gastrophilus, and characterised by the parasites, their eggs, or parasite debris in the mucosa, submucosa or tunica muscularis, surrounded by numerous lysozyme-positive macrophages and neutrophils, and more peripherally by abundant fibrous tissue containing variable numbers of immunoglobulin (Ig) G+ plasma cells, and small numbers of CD3+ T lymphocytes and IgM+ and IgA+ plasma cells. Anisakis simplex nematodes were found in two dolphins that were also parasitised by P gastrophilus and had parasitic granulomatous gastritis and multiple small chronic gastric ulcers. Lymphoplasmacytic enteritis was found in eight cases, three of them parasitised by Diphyllobothrium species; the lesion was characterised by moderate to severe infiltrations of CD3+ T lymphocytes and IgG+ plasma cells, with small numbers of IgM+ and IgA+ plasma cells in the lamina propria and submucosa, mainly of the small intestine. One dolphin had severe fibrinopurulent peritonitis, which may have been secondary to gastric perforation caused by the large mural granulomatous gastritis associated with P gastrophilus parasitism.

Abstract
This report describes a large cell immunoblastic lymphoma in a bottlenose dolphin found stranded alive in Gran Canaria, Spain. Diffuse infiltration of round neoplastic cells was observed in the splenic cords and sinuses and in hepatic sinusoids, resulting in moderate organ enlargement. The tumour cells (immunophenotype IgG+ and CD3-) showed scant, lightly eosinophilic or basophilic cytoplasm, distinct cell boundaries and hyperchromatic nuclei, each with one or more nucleoli. Mitoses were common. On the basis of histopathological, immunohistochemical and ultrastructural features, the tumour was classified as an immunoblastic lymphoma. Eleven polychlorinated biphenyl (PCB) congeners, 23 organochlorine pesticides and 16 polycyclic aromatic hydrocarbons (PAHs) were detected in the blubber and liver. High concentrations of PCBs 153, 180, 138 and 187 found in the liver may have been associated with the hepatosplenic lymphoma.

Abstract
Two adult ostriches developed anorexia, prostration, and severe hemorrhagic diarrhea, dying 24 hr after the onset of clinical signs. On postmortem examination, the cecal mucosa showed locally extensive areas of hemorrhages and fibrino-necrotic typhlitis with a white-yellowish material covering the mucosal surface. Multiple serosal petequial hemorrhages and fibrinous peritonitis were present. Histologic examination revealed an intense mononuclear infiltration in the lamina propria and submucosa of the cecum and extensive superficial necrosis associated with fibrin and serocellular deposits. Several gram-negative bacterial colonies were observed within the necrotic areas. Samples from intestinal lesions were collected, and pure growth of Escherichia fergusonii was obtained. Escherichia fergusonii is a member of Enterobacteriaceae, closely related to Escherichia coli and Shigella sp., established as a new species of the genus Escherichia in 1985. In veterinary medicine, E. fergusonii has been reported in calves and sheep from dinical cases suggestive of salmonellosis. To our knowledge, this report represents the first description of E. fergusonii associated with enteritis in ostrich.

Abstract
This article describes the gross, histopathologic, and ultrastructural findings of the livers of cetaceans stranded on the coast of the Canary Islands between 1992 and 2000. A total of 135 cetaceans were included in the study, among which 25 were common dolphins (Delphinus delphis), 23 Atlantic spotted dolphins (Stenella frontalis), 19 striped dolphins (Stenella coeruleoalba), and 15 other species of dolphins and whales. The most common lesion observed in these animals was a nonspecific chronic reactive hepatitis (47/135), followed by hyaline intracytoplasmic inclusions in hepatocytes (33/135). Parasitic cholangitis was detected in 8/135 animals, whereas hepatic lipidosis was presented in 7/135 animals. The ultrastructure of hyaline hepatocytic cytoplasmic inclusions is described, and possible causes of these inclusions are discussed.

Abstract
This study evaluates the cross-reactivity of seven anti-human and one anti-bovine antibodies in formalin-fixed, paraffin-embedded tissue samples of liver and mesenteric lymph nodes of 13 striped dolphins (Stenella coeruleoalba). Four antibodies (CD3, IgG, lysozyme and S100 protein) reacted with striped dolphin lymph nodes in a similar pattern to that observed in the species of origin. The anti-human MHC class II mAb reacted strongly with macrophages and dendritic-like cells of striped dolphins, whereas a small number of lymphocytes were labelled with this antibody. These antibodies were used to study the immunophenotype of the inflammatory infiltrated in non-specific chronic reactive hepatitis (eight cases) and chronic parasite cholangitis (two cases) and normal liver (three cases) of striped dolphins. Non-specific chronic reactive hepatitis was composed of inflammatory infiltration of CD3+ T lymphocytes and IgG+ plasma cells in portal spaces and hepatic sinusoids. Lymphonodular aggregates observed in chronic parasitic cholangitis showed a cellular distribution similar to that found in lymph node cortex, including the presence of S100+ and MHC class II+ dendritic-like cells in lymphoid follicles and interfollicular areas. This result suggests that those inflammatory infiltrates are highly organised to enhance antigen presentation to B and T cells.

Abstract
Left ventricular (LV) outflow tract-right atrial (RA) communication associated with bacterial endocarditis is described in a 6-year-old intact male Great Pyrenees dog with a 4- to 5-day history of fever, lethargy, weight loss, severe regenerative anemia, and asplenia. Typical vegetative mural endocardial lesions were observed grossly. Histologic evaluation revealed small gram-negative coccobacilli that were consistent with Bordetella avium-like organisms. These bacteria were associated with severe endocardial inflammation characterized by neutrophilic infiltration, extensive necrosis of endocardium, and fibrin deposition. LV-RA shunt (Gerbode defect) is a rare cardiac defect in humans that can be either congenital or, more rarely, secondary to septic endocarditis, valve replacement procedures, or thoracic trauma. B. avium-like organisms causing septicemia and endocarditis in immunocompromised and asplenic human patients have been described. To our knowledge, no previous descriptions of Gerbode defect associated with bacterial endocarditis in domestic animals have been reported in veterinary literature.

Abstract
Of 14 common dolphins, 12 showed non-specific reactive hepatitis and three chronic parasitic cholangitis with lymphoid proliferation. Non-specific reactive hepatitis was shown immunohistochemically to be associated with small clusters of CD3(+) cells in portal areas and hepatic sinusoids. Polyclonal antibody against S100 protein reacted with a variable number of lymphocytes from portal areas and hepatic sinusoids, as well as with Kupffer cells and epithelial cells of the bile ducts. The majority of plasma cells observed in portal areas and hepatic sinusoids were IgG(+). In lymphonodular lesions of chronic parasitic cholangitis, the distribution of immunoreactive cells was similar to that found in the cortex of lymph nodes. The presence of stellate cells similar to follicular dendritic and interdigitating cells expressing S-100 protein and MHC class II antigen in lymphonodular lesions suggested that these were highly organized structures developed to enhance antigen presentation to B and T cells.

Abstract
The purpose of this study was to define the normal anatomic structures in the canine larynx with magnetic resonance images. TI-weighted images were taken in the sagittal and transverse planes. The MR images were obtained comparing MR images to dissection planes. Magnetic resonance imaging provides excellent anatomic detail of laryngeal structures. Therefore, it is of value of diagnostic imaging of some respiratory diseases in the dog.
