Four female and 3 male Taita falcons (Falco fasciinucha) out of a breeding colony of 14 Taita falcons (7 pairs) died during the breeding season after showing lethargy and anorexia for 1 to 2 days. All animals were submitted for necropsy. Gross lesions in the female falcons were characterized by anemia secondary to marked hemorrhage into the ovary and oviduct, serofibrinous effusion into the cardioabdominal cavity and serosal petechiae. In addition, marked necrotizing splenitis and pulmonary hemorrhage were present. Histologically, the female falcons had mild necrotizing hepatitis with numerous intranuclear inclusion bodies and necrotizing splenitis with rare inclusion bodies. There were no gross lesions in the male falcons, and the histological lesions were characterized by urate deposition and rare intranuclear inclusion bodies in the renal tubular epithelial cells. Adenoviral particles were found by electron microscopy in the cloacal contents of the female Taita falcons but not in the male falcons. DNA in situ hybridization revealed widespread aviadenoviral nucleic acid within the nuclei of hepatocytes, renal tubular epithelial cells, and adrenal cells in the female falcons but no aviadenoviral nucleic acid in 1 male falcon and only a low quantity of adenoviral nucleic acid in the liver and kidney of another male Taita falcon. PCR amplified aviadenoviral DNA in the liver and intestine of all Taita falcons. The amplicons were sequenced, and the virus was identified as falcon adenovirus. The deaths of the female and male birds were attributed to the aviadenovirus infection.

Ornithine transcarbamoylase (OTC) deficiency is the most common hereditary urea cycle disorder. It is an X-linked recessive disorder that usually presents with encephalopathy and hyperammonaemia. We report a 14-month-old female carrier of OTC deficiency, who presented with a history of intermittent vomiting for 5 weeks and irritability and lethargy for 1 week. She was found to be in acute liver failure, with elevated transaminases, coagulopathy and a consistently low urea. Identifying an OTC mutation and ruling out other possible causes of acute hepatic failure confirmed the diagnosis. She was placed on low-protein diet supplemented with essential amino acids, and her liver enzymes, hyperammonaemia and coagulopathy corrected. Three other female patients have been reported with OTC deficiency presenting with severe cryptogenic hepatitis; our patient is unique in that the presentation of her disease was dominated by acute liver failure on a back ground of normal growth and development, no liver enlargement, and mild hyperammonaemia. OTC deficiency should be considered in the differential diagnosis of infants presenting with acute hepatocellular dysfunction, especially in females.

An adult female, albino South African Clawed frog (Xenopus laevis) from a research colony at the Biological Resources Facility of the College of Agriculture and Life Sciences at North Carolina State University (NCSU) was presented with depression, lethargy, loss of diving reflex, and a distended abdomen. Cytologic examination of coelomic effusion fluid at the NCSU veterinary teaching hospital revealed a mixed population of inflammatory cells, including heterophils and a predominance of large mononuclear cells (macrophages) that often contained intracytoplasmic, negatively-stained, rod-shaped to filamentous organisms consistent with Mycobacterium sp. Ziehl-Neelsen stain revealed bright pink to red, acid-fast organisms with a beaded appearance. Histopathologic findings in tissues obtained at necropsy included marked, multifocal to coalescing, heterophilic, granulomatous and fibrinous coelomitis as well as severe multifocal heterophilic and granulomatous hepatitis, interstitial pneumonia and sinusitis/rhinitis. Slender gram-positive, acid-fast bacterial rods were identified in sections of coelomic pleura, kidneys, nasal cavities, spleen, liver, and pulmonary interstitium, indicative of systemic mycobacteriosis. Based on mycobacterial culture, the organism was identified as M marinum complex. Mycobacteria are variably gram-positive, often acid-fast, small rods that are ubiquitous in aquatic environments. The clinical and pathologic spectrum of disease in amphibians depends on host and pathogen status. Xenopus sp and several other frogs are good models for studying the pathogenesis of M tuberculosis infection. In addition to culture, polymerase chain reaction assays may be used for definitive identification of the organisms; accurate speciation may require further genetic investigation.

A 3-month-old male Golden Retriever puppy was evaluated for lethargy and fever of 2-days duration. Results of a CBC and biochemical profile revealed marked eosinophilia (6.3 X 10(3)/microL; reference interval 0.1-1.2 X 10(3)/microL), moderate thrombocytopenia, and increased activities of alanine aminotransferase, aspartate aminotransferase, and creatine kinase. Hepatomegaly and peritoneal effusion were found using abdominal ultrasound. Peritoneal fluid analysis revealed eosinophilic inflammation (23,000 nucleated cells/microL with 88% eosinophils). Despite supportive treatment the puppy's condition deteriorated rapidly; euthanasia was requested, and a necropsy performed. Microscopically, there was marked necrosuppurative and eosinophilic hepatitis with vasculitis. Numerous hepatocytes contained protozoal organisms suspected to be Toxoplasma gondii or Neospora caninum. However, serum was negative for both T gondii and N caninum antibodies; polymerase chain reaction assay on hepatic tissue was negative for both organisms; and immunohistochemical evaluation of hepatic tissue using serum raised against T gondii, N caninum, and Sarcocystis neurona also was negative. Schizont morphology suggested that merozoites replicated by endopolygeny, forming rosettes around a central residual body. Transmission electron microscopy revealed that merozoites lacked rhoptries. These findings were consistent with a diagnosis of Sarcocystis canis, an apicomplexan parasite with an unknown life cycle.

A group of 12 domestic pigeons (Columba livia domestica) was treated for capillariasis by use of fenbendazole at 30 mg/kg orally once daily for 5 d. After treatment, 8 of the 12 pigeons exhibited signs of anorexia, lethargy, and dehydration; these birds died within 2 d after the onset of clinical signs. A total of 6 birds were necropsied, and all had unremarkable gross findings. Microscopic examination of tissues revealed acute hemorrhagic enteritis, diffuse lymphoplasmacytic enteritis, small intestinal crypt necrosis, periportal lymphoplasmacytic hepatitis, bile duct hyperplasia, and renal tubular necrosis. Erythrocytes in blood samples collected from surviving birds demonstrated polychromasia compatible with a regenerative anemia. The clinical and histopathologic findings in these pigeons were consistent with recent reports of fenbendazole toxicity in domestic pigeons and other columbiform birds.

A case of eosinophilic granulomatous gastroenterocolitis and hepatitis in a 1-year-old male Siberian Husky is described. The dog presented with a history of diarrhea, weakness, lethargy, and anorexia of several months' duration. Hematologic and biochemical examinations, abdominal ultrasonography, computer tomography, and exploratory laparotomy were performed. Histopathologic examination of full-thickness biopsies from the gastrointestinal tract and liver revealed the presence of eosinophilic granulomatous lesions in the submucosa and tunica muscularis of stomach, jejunum, ileum, colon, and liver. Infectious agents were not detected by light microscopic and electron microscopic examination or by immunohistochemistry. On the basis of the findings, it is concluded that the disease in this dog represents an unusual manifestation of chronic idiopathic inflammatory bowel disease.

A 57-year-old schizophrenic woman presented with lethargy, nausea, vomiting, and anorexia after coin ingestion. She was found to have multiple organ dysfunction manifested as hepatitis, pancreatitis, severe anemia with markedly depressed bone marrow response, extravascular hemolysis, and acute renal failure. Prolonged exposure to zinc from massive coin ingestion was responsible. Zinc poisoning is an unusual consequence of coin ingestion in the adult human literature. A detailed discussion on zinc poisoning, as well as the pitfalls in radiological diagnosis of massive coin ingestion, is presented.

Mice fed 1.5 mg ochratoxin A (OTA) per kg body weight and infected with Trypanosoma brucei rhodesiense were compared with trypanosome-infected placebo-fed and uninfected OTA-fed controls. Uninfected OTA-fed mice showed fever, lethargy, facial and eyelid oedemas, mild hepatitis and nephritis, and high survival. Infected placebo-fed controls had mean pre-patent period (PPP) of 3.26 days, lethargy, dyspnoea, fever, facial and scrotal oedema, survival of 33-65 days, reduced red cell counts (RCC: 10.96-6.87x106 cells/microl of blood), packed cell volume (PCV: 43.19-26.36%), haemoglobin levels (Hb: 13.37-7.92 g/dL) and mean corpuscular volume (MCV) of 37.96-41.31 fL, hepatosplenomegaly, generalized oedemas, heart congestion, hepatitis and nephritis. Compared to infected placebo-fed controls, infected OTA-fed mice had significantly (P<0.05) shorter mean PPP (2.58 days), reduced survival (6-47 days), more pronounced fever and dyspnoea. The latter had significantly (P<0.05) reduced RCC (10.74-4.56x106 cells/microl of blood), PCV (43.90-20.78%), Hb (13.06-5.74 g/dL), increased MCV (39.10-43.97 fL), severe generalized oedemas, haemorrhages, congestion, hepatic haemosiderosis, hepatitis, nephritis, endocarditis, pericarditis and exclusively, splenic macrophage and giant cell hyperplasia, expanded red pulp and splenic erythrophagocytosis. It was concluded that OTA aggravated the pathogenesis of T. b. rhodesiense infection in mice, and should therefore be taken into consideration during trypanosomosis control programmes.

Infectious canine hepatitis in 4 Dogs in Switzerland. Four dogs presented with nonspecific symptoms of lethargy, vomiting, diarrhea, fever and weakness. Laboratory results were consistent with hepatopathy and disseminated intravascular coagulation. Three dogs died, one survived. In the three deceased dogs, a diagnosis of infectious canine hepatitis (ICH) was made based on histological findings and positive immunhistochemistry results for canine adenovirus-1 (CAV-1). In the surviving dog, an antemortem diagnosis of ICH was determined via positive polymerase chain reaction results from blood, occular, nasal and preputial discharge as well as from urine. Since the introduction of widespread vaccination, the incidence of CAV-1 infection in dogs is low. However, the disease has not been eradicated and should be considered when clinical signs consistent with ICH are present.

Oropouche virus (OROV), of the family Bunyaviridae, is the second most frequent arbovirus causing febrile disease in Brazil. In spite of this, little is known about pathogenesis of OROV infection. This report describes an experimental model of OROV in golden hamster (Mesocricetus auratus). Following subcutaneous inoculation of OROV, over 50% of the animals developed disease characterized by lethargy, ruffled fur, shivering, paralysis, and approximately one third died. Animals were sacrificed on days 1, 3, 5, 8 and 11 post-inoculation to collect tissue samples from brain, heart, liver, lung, spleen, muscle and blood for virus titration, histology and OROV immunohistochemistry. OROV was detected in high titers in blood, liver and brain, but not in the other organs. Histopathology revealed meningoencephalitis and hepatitis, with abundant OROV antigen detected in liver and brain. Diffuse galectin-3 immunostaining in brain and liver supports microglial and Kupfer cells activation. This is the first description of an experimental model for OROV infection and should be helpful to study pathogenesis and possibly to test antiviral interventions such as drugs and vaccine candidates.
