Carotenoids in yellow-pigmented enterococci.

Pigments extracted from three strains of yellow enterococci showed the spectral and solvent partition characteristics of carotenoids. An unusual C(32) carotenoid aldehyde appears to predominate.

Dose-titration to confirm the level of fenbendazole for control of Raillietina cesticillus in broiler chickens.

A total of 452 broiler chickens, naturally infected with Raillietina cesticillus, were allotted into six treatment groups. One group was fed unmedicated broiler ration (Group 1), and the other five groups were fed broiler ration containing fenbendazole at 180 ppm for 3 days (38.5 mg/kg body weight [BW]), 240 ppm for 3 days (50.9 mg/kg BW), 120 ppm for 6 days (52.2 mg/kg BW), 180 ppm for 6 days (79.9 mg/kg BW), or 240 ppm for 6 days (104.3 mg/kg BW). Fenbendazole was 100.0% efficacious against R. cesticillus when administered in the diet at 240 ppm for 6 days; 99.9% at 240 ppm for 3 days and at 180 ppm for 6 days; 99.5% at 120 ppm for 6 days; and 96.9% at 180 ppm for 3 days. Fenbendazole treatment had no adverse effect on weight gain or feed intake.

Application of enzyme-linked immunosorbent assay for detecting antibody to Mycoplasma gallisepticum infections in poultry.

An enzyme-linked immunosorbent assay (MYCO-ELISA) was developed to detect antibodies to Mycoplasma gallisepticum (MG) in chicken sera. The assay was standardized in terms of optimum antigen concentration, serum dilution, conjugate dilution and incubation temperature, and time. The MYCO-ELISA antigen was prepared from MG whole bacterial cell or its disrupted cell suspension. Both preparations showed strong affinity for binding or adsorbing to the surface of polystyrene wells of the microtiter plate. The MYCO-ELISA was more sensitive than the hemagglutination-inhibition test. However, cross-reactions were observed with sera from M. synoviae (MS)-infected birds.
