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)
In a seroepidemiological survey using an indirect haemagglutination assay, the prevalence rate of toxoplasmosis in central Ethiopia was 22.9% of 899 sheep, 11.6% of 753 goats and 6.6% of 785 cattle. There were high titres of 1:256 or more which suggest current infections. These results indicate that toxoplasmosis may be an important cause of reproductive(More)
A study was conducted to investigate causes of lamb morbidity and mortality on farms and on-station at Debre Berhan during 1989 and 1990. It showed pneumonia (bacterial and/or verminous), starvation-mismothering exposure (SME) complex, gastrointestinal parasites, enteritis, abomasal impaction and physical injuries to be important health constraints on(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)
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)
Rats received daily oral doses of 15, 50, 150, or 200 mg/kg CI-1000 for 4 weeks. Doses were selected based on findings from a 2-week range-finding study where doses of 250 and 500 mg/kg resulted in mortality. In the 4-week study, females given 200 mg/kg were sacrificed during Week 2 due to poor condition. Serum creatinine and urea nitrogen increased 2- to(More)
