Medical records of thirty-five consecutive cases of canine granulocytic ehrlichiosis (CGE) diagnosed cytologically in Central Italy in 1995-2000 were analysed retrospectively. Tick exposure was reported in 16 dogs (45.7%) and concurrent babesiosis in 19 dogs (54.3%). Ehrlichia-like inclusion bodies were found in neutrophils in a percentage varying from 0.5% to 11%. Frequently recorded clinical signs included anorexia (71.4%), lethargy (45.7%), conjunctivitis (31.4%), fever (25.7%), lameness (20%) and ataxia (20%). Among the 16 representative dogs in which protein, electrophoresis was performed, 10 (62.5%) showed high globulin levels and 6 (37.5%) had concurrent high total protein levels. During treatment with doxycycline, all associated symptoms, including those unusually described, such as pyoderma intertrigo, erythema, apparent blindness and oral papillomatosis, progressively disappeared in 31 (89%) out of 35 dogs. The efficacy of treatment was marked in dogs simultaneously treated twice with imidocarb dipropionate: among the 14 dogs in which a fast recovery was noted, 11 (80%) were concurrently affected by babesiosis and consequently treated with the specific medicament leading to excellent outcomes. The main conclusion is that CGE is present among dogs from Central Italy and should be included in the differential diagnosis of possible zoonotic agents affecting the canine population.

A 3-year-old Staffordshire Terrier was presented to the Texas Veterinary Medical Center with a short progressive history of anorexia, weight loss, and weakness that had progressed to ataxia and collapse with empirical treatment. The dog was tetraparetic and obtunded. Results of a complete neurologic evaluation were consistent with severe, multifocal to diffuse disease involving the forebrain, spinal cord, and brainstem. Cerebrospinal fluid, obtained via cerebellomedullary cisternal puncture, was highly cellular and contained large atypical round cells with small numbers of nondegenerate neutrophils and large mononuclear cells. Rare eosinophils and small lymphocytes were noted. The atypical round cells were approximately 15-25 micro m in diameter with a single nucleus set in a small amount of cytoplasm. The nuclei were typically round to slightly ovoid; however, occasional notched, lobulated, and reniform nuclei were observed. These cells were interpreted as malignant lymphocytes. Owing to a grave prognosis, the animal was euthanized and a necropsy was performed. No gross lesions were found in the central nervous system. Multiple sections of cerebellum, medulla, and spinal cord contained a diffuse neoplastic infiltrate that was predominantly meningeal with rare superficial neuropil invasion. The neoplastic cells were arranged in sheets, cords, and rosettes. Immunohistochemical staining for vimentin, pancytokeratin, CD3, CD79a, synaptophysin, S-100, and neuron-specific enolase was negative; glial fibrillary acidic protein (GFAP) staining was equivocal. Based on histologic findings, a diagnosis of medulloblastoma was made. This case documents the rare occurrence of a canine medulloblastoma and illustrates the difficulty in distinguishing between some embryonal brain tumors and lymphoma.

Blastomycosis was diagnosed in six nondomestic felids from eastern Tennessee, including two Asian lions (Panthera leo persicus), one African lion (Panthera leo), one Siberian tiger (Panthera tigris), one cheetah (Acinonyx jubatus), and one snow leopard (Panthera uncia). Clinical signs included lethargy, anorexia, weight loss, dyspnea, sneezing. ataxia, and paresis. Variable nonspecific changes included leukocytosis, monocytosis, moderate left shift of neutrophils, moderate hypercalcemia, hyperproteinemia, and hyperglobulinemia. Thoracic radiographs revealed interstitial and alveolar changes, consolidation or collapse of a lung lobe, bullae formation, and a pulmonary mass. Agar gel immunodiffusion (AGID) serology for Blastomyces dermatitidis was performed in five felids and was positive in three. The tiger had cerebral blastomycosis and was positive for AGID serologic tests of both cerebrospinal fluid and serum. One percutaneous lung aspirate in the snow leopard and one bronchial aspirate in an Asian lion demonstrated B. dermatitidis organisms. whereas tracheal wash samples and a nasal discharge were nondiagnostic in others. Treatment with itraconazole was attempted in four cats. The tiger improved before euthanasia, whereas the others did not survive beyond initial treatments. In four felids, B. dermatitidis was found in the lungs and tracheobronchial lymph nodes associated with a florid pyogranulomatous reaction; the tiger had a pyogranulomatous encephalomyelitis, and the cheetah had a single pulmonary granuloma. Thoracic radiography, cytologic examination of lung lesion aspirates, and B. dermatitidis AGID serology should be performed on clinically ill zoo felids in endemic areas to rule out blastomycosis.

An epizootic of toxoplasmosis occurred among 22 adult and 30 kit black-footed ferrets (Mustela nigripes) maintained under quarantine conditions at the Louisville Zoological Garden (Louisville, Kentucky, USA) in June, 1992. Black-footed ferrets appear to be highly susceptible to acute and chronic toxoplasmosis. Clinical signs were observed in 19 adults and six kits and included anorexia, lethargy, corneal edema, and ataxia. Two adults and six kits died with acute disease. High antibody titers to Toxoplasma gondii were detected by latex agglutination and modified agglutination assay in 10 black-footed ferrets. One adult and six kits that died with acute clinical signs were necropsied and T. gondii-like organisms were found microscopically in multiple organs. Diagnosis of toxoplasmosis was confirmed by immunohistochemical staining with anti-T. gondii antibodies and by ultrastructural examination. Although the source of T. gondii for black-footed ferrets was not identified, frozen uncooked rabbit was the most likely source. Chronic toxoplasmosis resulted in the death of at additional 13 black-footed ferrets that were adults during the epizootic. Affected animals developed chronic progressive posterior weakness and posterior ataxia 6-69 mo after the epizootic began. Meningoencephalitis or meningoencephalomyelitis associated with chronic toxoplasmosis were identified at necropsy in all 13 ferrets. Precautions to prevent introduction of pathogens into the colony were insufficient to exclude T. gondii. Although toxoplasmosis may cause significant mortality in mustelids, the high mortality of black-footed ferrets in this epizootic was of concern due to their endangered status. This is the first detailed report of toxoplasmosis in black-footed ferrets.

Over a 44-day period, 4 of 5 affected calves in a 170-head herd of beef cattle died after exhibiting clinical signs of lethargy, ataxia, anorexia, and diarrhea. Histopathological examination of tissues and toxicological analysis of a suspicious powder discovered in the pasture confirmed arsenic trioxide toxicosis.

A case of West Nile virus (WNV) infection in a captive 4-month-old Arctic wolf (Canis lupus) is described. The animal had vomiting, anorexia, and ataxia before death. Histopathology revealed multifocal severe renal lymphoplasmacytic vasculitis, mostly affecting small arterioles, with fibrinoid degeneration of some vessel walls. Many small foci of gliosis were detected in the cerebral cortex. West Nile virus was demonstrated in the kidneys and cerebrum by immunohistochemistry and polymerase chain reaction. The described renal changes represent a novel pathological finding of WNV infection.

A male alpaca acutely developed signs of anorexia and fever. Within 2 days, neurologic signs (head tremors and asymmetric ataxia) developed. West Nile virus (WNV) infection was considered a primary differential diagnosis on the basis of 6 previous cases on nearby alpaca farms on which animals had similar clinical signs. Four days after the male alpaca became ill, a female alpaca from the same farm developed similar neurologic signs. In addition to anti-inflammatory and supportive treatments, both alpacas received a transfusion of llama plasma with antibodies against WNV Seven days after the onset of clinical signs, the female alpaca had made a full recovery; however, the more severely affected male died. West Nile virus infection was confirmed post mortem by use of reverse transcriptase-polymerase chain reaction assay and immunohistochemical staining.

Ten dogs with neuroendocrine carcinoma of the liver were selected for inclusion in the study. Clinical signs were anorexia (7), vomiting (5), polydipsia/polyuria (3), icterus (2), lethargy (2), weight loss (2), paresis (1), ataxia (1), weakness (1), collapse (1), and urinary tract infection (1). Hematologic and biochemical abnormalities included anemia (2/8), leukocytosis (4/8), high liver enzyme activity (serum alkaline phosphatase, 7/9; alanine transaminase, 7/9; aspartate transaminase, 8/9), and high total bilirubin (6/9). Grossly, the tumors were diffuse, involving all liver lobes in six dogs, and two dogs had various-sized nodules in addition to diffuse involvement. Histologically, there were eight tumors with solid or trabecular pattern (group A), one tumor with cords or rows of neoplastic cells (group B), and one tumor with multiple rosette-like structures (group C). Immunohistochemical studies revealed that all 10 neoplasms were positive for at least one of the endocrine markers used: neuron-specific enolase (NSE; 8/10), synaptophysin (5/10), and chromogranin-A (3/10). A panel of NSE, chromagranin-A, and synaptophysin detected 100% of the tumors in our series. Electron microscopy confirmed the diagnosis by the presence of intracytoplasmic neurosecretory granules in the two examined cases. Our results show that neuroendocrine markers commonly used in humans can be used for the diagnosis of hepatic neuroendocrine carcinoma in dogs, preferably a panel of synaptophysin, chromagranin-A, and NSE because chromogranin-A alone is not as useful in dogs as in humans.

Eastern equine encephalitis (EEE) was diagnosed in a flock of African penguins. Diagnosis was based on history and clinical signs and confirmed via serologic testing, virus isolation, reverse transcriptase-polymerase chain reaction (RT-PCR) assay, and histologic examination. Clinical signs in penguins included anorexia, behavior changes, depression, regurgitation, ataxia, recumbency, and seizures, and some penguins did not have any clinical signs. Mean +/- SD number of days that affected penguins had clinical signs was 12 +/- 5 days. Abnormalities initially detected on CBC included heterophilic leukocytosis and anemia; lymphocytosis and monocytosis were detected later. Plasma biochemical abnormalities included high activities of aspartate amino-transferase and creatine kinase, hyponatremia, hypochloremia, hyperglycemia, and high concentrations of globulin, triglycerides, and cholesterol. Mean +/- SD number of days required for resolution of CBC and plasma biochemical abnormalities was 67 +/- 24 days after the onset of clinical signs. Treatment consisted of supportive therapy. All penguins survived with the exception of one that was euthanatized; histopathologic findings were consistent with encephalitis. Results of RT-PCR assays performed on tissue from the right cerebrum of the penguin that was euthanatized were positive for EEE viral RNA. An inability to isolate virus several weeks after illness suggested successful viral clearance in recovered penguins. To the authors' knowledge, EEE infection in any penguin species has not been reported.

The aim of this study was to evaluate the efficacy and tolerability of iron protein succinylate in the treatment of iron-deficiency anemia in pregnancy. One hundred and thirty anemic pregnant women were studied. Inclusion criteria were iron-deficiency type of anemia, and hemoglobin levels below of 11.5, 10.9 and 10.3 g/dl for the three trimesters of pregnancy, respectively. Twenty-five women who presented pregnancy-related complications were excluded during treatment. The remaining 105 were treated with 1600-mg iron protein succinylate per os daily for a period of four months. A group of anemia-related clinical signs and symptoms, and hematological parameters were recorded at the beginning of treatment, as well as two and four months later. They included epidermis and mucosal paleness, skin and nail lesions, glossitis, heart pulse, sickness, anorexia, apathy, ataxia, polypnea, insomnia, nervousness, paresthesias and other neurological symptoms; the hematological parameters included Hgb, hct, RBCs, WBCs, MCV, MCH, MCHC, PLTs, serum Fe and ferritin. Possible side or adverse effects were considered during treatment. The majority of symptoms and signs of anemia were gradually improved. There was a statistically significant increase in the means of Hgb, hct, WBCs, MCV, MCH, PLTs and serum ferritin (p < 0.05). Anemia was effectively treated in 100/105 (95.2%) women, but not in five patients (4.8%) who displayed poor compliance to the therapeutic protocol. There were transient and mild side-effects in seven (6.6%) treated women, namely diarrhea, epigastralgia, vomiting, and nausea, which however, did not necessitate discontinuation of the therapeutic protocol. Iron protein succinylate is an effective and well tolerated treatment of iron-deficiency anemia in pregnancy.
