Infection of the peritoneal cavity with cestode larvae, presumptively diagnosed as tetrathyridia of the genus Mesocestoides, was found by exploratory celiotomy in a dog with clinical signs consisting of episodic anorexia, vomiting, and depression. Lymphopenia and hypoalbuminemia were associated clinicopathologic abnormalities. Dystrophic calcification and midline duodenal displacement were found on abdominal radiographs. Therapy with mebendazole was instituted after recurrence of the initial episodic clinical signs postoperatively. Daily use of mebendazole for intermittent periods of up to 3 months led to remission of gastrointestinal signs for 30 months. However, 17 months after the initial diagnosis, infection of the vaginal tunic of the testicle with similar cestode larvae necessitated castration and removal of the vaginal tunic to the inguinal ring. Mebendazole therapy was reinstituted and continued for 31/2 months postoperatively. The dog was free of clinical signs of infection during and for the 16 months since this period of treatment.

Hyponatremia with simultaneous renal sodium loss was associated with the inappropriate secretion of antidiuretic hormone in a dog with heartworm disease. Antidiuresis caused expansion of extracellular fluid volume, which induced renal salt wasting and a negative sodium balance. The combination of water retention, salt wasting, and inactivation of intracellular solute contributes to the decrease in serum sodium concentration. Water intoxication due to hypotonicity of body gluids induced anorexia, depression, weakness, and incoordination.

Cattle consuming only Kochia scoparia in a pasture southeastern Colorado became ill. Clinical signs were lacrimation, depression, anorexia, nystagmus, head pressing, and recumbency. Some cattle died acutely, with the only clinical signs being recumbency, nystagmus, and occasionally opisthotonos. Pathologic findings were pulmonary edema and congestion, hepatic necrosis and fibrosis, necrosis of proximal convoluted tubular epithelium in the kidneys, epidermal necrosis of lightly pigmented areas, and laminar cerebrocortical necrosis. When the cattle were removed from the pasture, the problem ceased.

Ten captive-reared African black-footed penguins (Spheniscus demersus) from a large outdoor colony were monitored for avian malaria, using several diagnostic tests. One treatment regimen was evaluated. Thin smear blood evaluation enabled detection of seven parasitemias involving Plasmodium relictum and Plasmodium elongatum in the penguins. Leukocytosis (relative lymphocytosis) was characteristic of infected birds. Parasitemia was detected as early as 21 days prior to onset of clinical signs (depression, anorexia, regurgitation, pale mucous membranes, and respiratory distress). The single bird that died had clinical signs only a few hours prior to its death. Treatment consisted of 0.03 mg of primaquine phosphate base/kg body weight, administered orally once daily for 3 days. Oral chloroquine phosphate therapy, given simultaneously, was administered in an initial loading dose of 10 mg of chloroquine phosphate base/kg body weight, followed by doses of 5 mg/kg at 6, 18 and 24 hours after the initial chloroquine dose. This treatment regimen prevented mortality and cleared parasites from the blood. Recurrences of malaria occurred in two birds that had received this treatment.

Pathological examination was carried out on a male and a female beef calf 3 months old involved in an outbreak of xanthinurolithiasis. This outbreak has been found among indigenous Japanese Black calves in an area of the Kyushu region since 1971. Involved in it, calves were retarded in growth, with the back curved, exhibiting depression and anorexia. A characteristic gross change was the accumulation of yellowish white or yellowish brown sand-grain-like calculi in the urinary passage. Histologically, a number of calculi, as birefractive crystals, were contained mainly in the collecting and distal uriniferous tubules in the renal medulla. In the uriniferous tubules epithelial cells surrounding those crystals presented such reaction as to form syncytia, and the surrounding connective tissue proliferated. Biochemical examination revealed that the calculi were composed of xanthine.

Canine ehrlichiosis was successfully transmitted from the domestic dog to three Wild Dogs Lycaon pictus and three Black-backed Jackals Canis mesomelas. Wild Dogs showed symptoms of anorexia and depression as well as anaemia, leucopaenia and mild thrombocytopaenia. Black-backed Jackals were asymptomatic. Morulae of Ehrlichicia canis were found in peripheral blood smears from all experimental animals. The disease was also successfully transmitted from Black-backed Jackal to the domestic dog.

The oral administration of phenylbutazone at a dose rate of approximately 10 mg per kg per day for seven to 14 days resulted in the development of signs of toxicity in seven of eight ponies treated. Clinical signs included anorexia, depression and abdominal oedema. Blood biochemical determinations showed a decrease in total plasma protein and calcium concentrations with an increase in urea concentration. These changes were considered indicative of water retention. Three of the ponies died during treatment following the development of shock. Shock was considered to arise from the submucosal oedema of the large intestine observed on necropsy. Oral ulceration was also found in these animals. In two ponies intravenous administration of phenylbutazone (4.0 mg per kg) for seven days was studied. In one of these ponies a marked decrease in total plasma protein concentration occurred.

An outbreak of chronic liver disease was investigated in a kennel of dogs. Anorexia, depression, polyuria, polydipsia, icterus and a terminal hemorrhagic diathesis were noted in clinically affected dogs. Thrombocytopenia, hypofibrinogenemia, elevated fibrinogen degradation products and prolonged activated partial thrombosplastin times (PTT) and one-stage prothrombin times (PT) were associated with the hemorrhagic crisis. Aflatoxicosis was confirmed by the presence of significant levels of aflatoxicosis was confirmed by the presence of significant levels of aflatoxin B in the commercial dog food being fed. A subacute hepatitis was found on necropsy. Disseminated intravascular coagulation was suspected as the cause of the hemorrhage in these cases and treatment was instituted.

Salmonellosis in horses may result in fever, anorexia, and depression without concurrent diarrhea or other obvious gastrointestinal abnormalities and should be considered in cases of fever of unknown origin. The syndrome also is characterized by neutropenia, usually with a left shift, and growth of small numbers of salmonella from feces cultured in selenite enrichment broth. Repeated culturing may be necessary to isolate the organism. All six affected horses of this report recovered in 3 to 7 days without specific therapy.

Examined was material taken from five sheep (ewes) and two weaned lambs having naturally contracted Qu rickettsiosis. Described are the clinical symptoms of the disease and the morphologic changes. The diseased animals showed rise in temperature (39.5--40.5 degrees C), loss of appetite, and depression. Some of the weaned lambs manifested slight cough and digestive troubles. Part of the animals showed nervous symptoms--tic movements of the head and limbs. Morphologically, the liver was edematired, of lower compactness, and the spleen was enlarged, the meninges being hyperemic and peppered with pinpointed hemorrhages. Histologically, a strong diffuse activation and proliferation of the liver capillary endothelium was established along with necrobiosis of the liver epithelial cells and a diffuse leukocyte infiltration. Established was also hyperplasia of the reticular cells and the lymph follicles of the spleen and the bronchial lymph nodes. The epithelial cells of the kidney tubules were involved in vacuolar dystrophy, and in the medular section there were fibroblastic proliferations with hyperemia. Inflammatory changes in the brain were also found.
