Drug resistance evaluation of some commonly used anti-coccidial drugs in broiler chickens.

The study investigated some anticoccidial resistance for Amprol, Toltrazuril and sulfaclozine in experimental infected broiler. Eimeria identification depended on necropsy and coproscopic examination. 140 day-old chicks allotted into 7 groups and infected with Eimeria in 2nd day of age. G1: neither infected nor treated (negative control), G2: infected but not treated (positive control), Infected and treated with toltrazuril (G3), or with Amprol+Allicin (G4), or with Amprol+ethobabate (G5), or with Amprol (G6) or with Sulfaclozine (G7). Eimeria infection caused decrease in body gain, total protein, albumin but increase in FCR, ALT, AST, Uric acid, Creatinine. Treatment decreased the harmful effect of infection but some significant differences were between infected treated groups and non infected non-treated one.

Hepatitis C and B viruses, and their association with hepatocellular carcinoma in Egypt.

Hepatitis C and B viruses are associated with hepatocellular carcinoma in Europe, Asia and Southern Africa. A study of hepatitis C and hepatitis B virus infection was carried out on 70 patients with HCC, from the National Cancer Institute, Cairo University. Sera from patients were tested for anti-HCV and HBsAg markers. Twenty patients (30%) were anti HCV positive alone, 15 (21.4%) were HBsAg positive alone, 28 (40%) were positive for both anti-HCV and HBsAg and the remaining 6 patients (8.6%) were negative for the two markers. The total positivity for anti-HCV and for HBsAg in these patients was 70% and 61.4% respectively. The comparable figures in a recent study on 90 blood donors from Egypt, were 24.4% for anti-HCV and 4.4% for HBSAg. These data suggest a possible link between HCV and HBV infection and the development of hepatocellular carcinoma in Egypt, as has been found elsewhere in the world.
