Five hundred and sixty sheep, slaughtered at an Addis Ababa abattoir, were examined for cysticercosis and hydatidosis. The prevalence of the metacestodes of Taenia hydatigena was 37.1% and that of Echinococcus granulosus 16.4%. In addition, the age and sex prevalences of hydatid cysts, their organ distribution and the ratio of fertile cysts were determined.
A class effect of quinolone antibacterial agents observed during animal toxicity testing is a specific arthropathy (QAP). Despite the growing list of laboratory animals susceptible to QAP and reports of arthralgia in patients treated with quinolones, the potential for QAP development in humans remains unknown. This review discusses current concepts in the… (More)
3-Acetyldeoxynivalenol was incorporated into a semisynthetic diet at levels of 2.5, 5, 10 or 20 ppm and fed to mice for up to 48 days. Body weights and feed consumption were determined, and blood samples for hematological evaluation were taken. Selected tissues were examined microscopically and the humoral immune response was assessed using the Jerne plaque… (More)
Mice were killed 2, 4, 6, 12, 24, 48 and 96 hours after intragastrical administration of 0, 5, 10, 20, or 40 mg/kg body weight of 3-acetyldeoxynivalenol. The animals became clinically ill after 12 hours and some animals in the highest dose group died. Histological examination of duodenal crypts, thymus and spleen revealed, in all dose groups, presence of… (More)
A case of severe focal granulomatous dermatitis in a 10-year-old neutered male domestic short-haired cat due to a dematiaceous fungus, Phialophora gougerotii is described. The infection is believed to be secondary to squamous cell carcinoma of the nasal septum.
The effect of ingestion of dried leaves of Cestrum diurnum, a plant shown to contain a 1,25-dihydroxycholecalciferol-like principle, was tested in normal pigs fed 1.2% calcium and 1.0% phosphorus for 10 weeks from weaning and in hyperparathyroid pigs fed 0.8% calcium and 1.6% phosphorus for the same periods of time. Addition of 3% Cestrum diurnum leaf meal… (More)
To determine the effect of midazolam on ketamine-xylazine anesthesia, 20 guinea fowl (Numida meleagris galeata) were randomly divided into 2 groups. Birds in group KX were anesthetized with ketamine (15 mg/kg i.m.) and xylazine (2.5 mg/kg i.m.), whereas the birds anesthetized in group KXM received midazolam (0.3 mg/kg i.m.) in addition to the ketamine and… (More)
CI-994 (acetyldinaline) is an orally active anticancer drug currently in Phase 1 clinical trials. To assess its preclinical toxicity, CI-994 was administered orally as suspensions to Wistar rats (10/sex/dose) and in capsules to beagle dogs (3/sex/dose) once daily for two weeks. Doses were 1.5, 5, and 15 mg/kg for rats (9, 30, and 90 mg/m2, respectively),… (More)
