Studies of a glycoprotein in the oocysts of Eimeria tenella.
A glycoprotein unique to the cytoplasm of the unsporulated oocyst of Eimeria tenella has been purified and partially characterized. The protein has a molecular weight of 30,000, of which approximately 40% is carbohydrate. The carbohydrate portion of the molecule consists of glucose, galactose, mannose, xylose, glucosamine, and galactosamine, with no detectable sialic acid. The protein portion c...
متن کاملINTRATRACHEAL INFECTION OF CmCKHNS WITH SPORULATED OOCYSTS OF EIMERIA TENELLA
Sanda A., Salman Al Said: Intratracheal Infection of Chickens with Sporulated Oocysts of Eimeria tenella. Acta vet. Bmo, 47, 1978: 185-187. Experiment involving 16 treated and 10 control chickens, aged 3 weeks, was conducted to study the intratracheal route of infection by sporulated oocysts of Eimeria tenella. In the experimental birds a surgical procedure was conducted to prevent ingestion of...
متن کاملIn vitro Anticoccidial Activity of Methanolic Leaves Extract of Lannea schimperi Against Oocysts of Eimeria tenella
Eimeria belonging to the phylum apicomplexan protozoa is recognized as the the major parasitic disease of poultry. Caecal coccidioisis caused by Eimeria tenella is a major threat to poultry production. The drugs which can inhibit sporulation process are best choice as preventive measures. Anticoccidial drugs have played a major role in the effective control of avian coccidiosis, but their exten...
متن کاملIn vitro evaluation of the disinfection efficacy on Eimeria tenella unsporulated oocysts isolated from broilers.
The objective of this study was to evaluate in vitro the action of eight chemical principles by disinfection efficacy (DE) of Eimeria tenella oocysts. Disinfection efficacy was evaluated by either destruction or sporulation inhibition of the oocysts. Eight treatments were performed: T1 (Glutaraldehyde 42.5 g + Benzalkonium Chloride 7.5 g); T2 (Benzalkonium chloride + quaternary ammonium salt); ...
متن کاملEffects of Different Sizes of Glass Beads on the Release of Sporocysts from Eimeria tenella Oocysts
The oocyst wall is severed by means of mechanical injury or chemical agents. This study reports the percentage of in vitro sporocyst release following mechanical shaking in the presence of varying sizes of glass beads. Glass beads measured 0.5, 1, and 3 mm in diameter and were shaken with the oocysts for different times ranging from 5 sec to 5 min. Approximately 80% of sporocysts were released ...
