The enterotoxemic from of calf colibacteriosis was observed on a total of 18 occasions in newborn animals. Clinically, the disease was manifested with diarrhea, depression of the eyes, fast dehydration, the calves tending to go down and lie for a prolonged periods, with high death rates. Some of the diseased calves showed nervous symptoms. Escherichia coli 0126 was isolated from the intestinal content and the mesenterial lymph of the affected calves. It proved virulent for albino mice. Morphologically, there were strongly expressed circulatory disturbances--hyperemia, perivascular edemas, hemorrhages (Fig. 1 and 2) thrombi (Fig. 3 and 5), with a vacuolar and parenchymal dystrophia of the liver, kidneys, and heart.

Enterotoxigenic colibacillosis was experimentally produced in 8 of 9 colostrum-fed calves orally given 10(11) Escherichia coli. The eight calves developed profuse diarrhea accompanied by dehydration and depression. At 12 hours after exposure, all calves were euthanatized for necropsy and for collection of tissues for microscopic examination. Histopathologic changes included stunted villi in the jejunum and ileum, focal degeneration and exfoliation of absorptive epithelial cells at the tips of jejunal and ileal villi, and focal emigration of neutrophils which was especially prominent above the dome area of aggregated lymphatic follicles (Peyer's patches). A layer of E coli adhered to the epithelial surface of the jejunum and ileum. In the duodenum, lesions were minimal or absent and bacteria were not adhering to the mucosa. Histopathologic changes were not observed in other tissues. In two calves examined 24 hours after they were inoculated and in two calves euthanatized 24 to 36 hours after spontaneously developing enteric colibacillosis, lesions were similar to those observed in the calves at 12 hours after exposure.

Cholera toxin may depress cell-mediated immunity by stimulation of adenyl cyclase and production of cyclic AMP in cellular systems or when given parenterally to experimental animals. Whether or not similar effects might be found during clinical infection with Vibrio cholerae was the subject of this study. Delayed hypersensitivity reactions to skin test antigens were found to be markedly depressed in Bengali patients with cholera 24 h after fluid repletion. Skin test response rates were lower in children and in adults with the disease than in both normal adults and children or in adults with an equivalent degree of malnutrition. Patients with equal degrees of dehydration due to noncholera diarrhea were significantly less immunosuppressed. Concurrent depression of other manifestations of cell-mediated immunity was not found.

Food intake, appetite and a variety of feelings were measured pre- and post-operatively in obese patients undergoing jejuno-ileal bypass surgery. Decreased food intake correlated closely with the amount of weight loss at both 4 and 30 months after surgery. Malabsorption correlated with weight loss at 4 months but not 30 months post-operatively. The cause of the decreased food intake is unknown and cannot be completely explained by either depression, nausea, malabsorption, liver disease, an attempt to avert diarrhoea, or decreased appetite.

A 62-year-old man spread maneb on about 200 sq m of garden and subsequently was taken to the emergency clinic with complaints of oliguria, diarrhea, and hoarseness. Based on the clinicobiochemical data, he was found to have acute renal failure; the serum levels of BUN, creatinine, and potassium were 144.3 mg/dL, 14 mg/dL, and 5.8 mEq/L, respectively. The ST segment depression in V4-6, reciprocal ST segment elevation in V1-3, and inverted T waves in V5 and V6 were recorded on ECGs. Both the renal failure and the ECG abnormalities disappeared after hemodialysis. The possibility exists that the maneb caused the acute renal failure.

Semiacute toxicity of cola fluid, Coca-Cola, conducting for approximately a month in rats, was studied. A trend of cariogenicity of Coca-Cola was strongly indicated. When the fluid was given ad libitum, decarbonized Coca-Cola and carbohydrate solution, consisted 8% of glucose and 3.5% of sugar and then adjusted pH to 2.4 with oxalic acid, were consumed 2 to 3 times greater than the control (water). A hyperuresis was observed as the result of great consumption of liquid, but no liver nor kidney degeneration was observed by histopathological examination. The diet consumption of the groups of Coca-Cola and carbohydrate solution was approximately a half of the control, water. However, when a complete diet was given, no physiological difference in time was observed, except in diarrhea and depression of hair gloss in Coca-Cola group.

Malignant catarrhal fever was diagnosed in 3 herds of American bison (Bison bison) in South Dakota from 1973 to 1976. Clinical signs included depression, nasal and ocular discharge, conjunctivitis and keratitis, and diarrhea. Herd morbidity ranged from 3 to 53.8%, and mortality was 100%. At necropsy, ulcerative lesions were found throughout the alimentary tract, trachea, and bronchi. Microscopically, necrotizing vasculitis without thrombosis was found in virtually every organ examined.

A single administration of ifenprodil at the doses of 100, 200 and 400 mg/kg (p.o.), and 50 and 100 mg/kg (i.m.) produced a moderate CNS depression in rats, such as, sedation, ptosis, systemic muscle relaxation and decrease in motor activity. These symptoms appeared dose-dependently and persisted for about 4 hours following administration. In a direct physical dependence test, 5 groups of rats were fed the ifenprodil-admixed food together with drinking water ad libitum for 24 hours daily for 53 approximately 103 days (mean ifenprodil intake, 43--240 mg/kg/day), on the gradedly increased dosage schedule with a dosage level of 0.5 vs. 1 mg/g food to 4 mg/g food. In the natural withdrawal following administration, no significant withdrawal signs were observed in any group. In a substitution test either for phenobarbital or morphine, no suppression of withdrawal signs during the period of cross-administration of ifenprodil and no maintenance of dependence were observed. In a physical dependence-producing test, the rats fed ifenprodil never manifested withdrawal signs such as diarrhea, "wet shakes", sudden loss of body weight as in the levallorphan precipitation test. Ifenprodil apparently has no physical dependence liability.

Six cats were given chloramphenicol orally at the dose level of 120/mg/kg/day in 3 divided doses for 14 days and were then observed for another 3 weeks after treatment. Five other cats were used as untreated controls for the first 14 days and subsequently were given 60 mg of chloramphenicol/kg/day for 21 days. Clinical signs of toxicosis, which were more severe in cats given the higher dose level, included central nervous system depression, dehydration, reduced food intake, body weight loss, sporadic diarrhea, and vomiting. In cats given the higher dose level, chloramphenicol caused reversible marrow suppression, with marrow hypoplasia, maturation arrest of erythroid cells, and inhibition of mitotic activity, and caused vacuolation of lymphocytes and of early myeloid and erythroid cells. Significant changes were evident in bone marrow after treatment for 1 week and in peripheral blood at the end of the 2nd week. Hematologic changes included decreased numbers of neutrophils, lymphocytes, reticulocytes, and platelets. In cats given the lower dose level, changes in blood and bone marrow were similar but less severe.

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.
