@article{yersin_edens_simmons_1991, title={EFFECT OF BORDETELLA AVIUM INFECTION ON ELECTROCARDIOGRAMS IN TURKEY POULTS}, volume={35}, ISSN={["1938-4351"]}, DOI={10.2307/1591594}, abstractNote={Electrocardiograms (ECGs) were recorded from turkey poults infected with the W isolate of Bordetella avium. Strip chart data (amplitudes and intervals) were measured at 7, 14, 21, and 28 days postinoculation and compared with data from uninoculated controls. B. avium infection altered P-, RS-, and T-wave amplitudes, as well as P-R and S-T intervals throughout the 4-week experimental period. Heart rates were similar over the 4-week period in control poults, while rates in the infected birds were variable. Alterations in ECGs associated with B. avium infection appeared to be the result of disturbances in the cardiovascular system and may be associated with the pathogenicity of the organism in turkey coryza.}, number={4}, journal={AVIAN DISEASES}, author={YERSIN, AG and EDENS, FW and SIMMONS, DG}, year={1991}, pages={668–673} }

Fourteen days postinoculation, tracheal sections were examined by histological and morphometrical analysis of cilia, as well as agar plate isolation for bacteria. Infected poults exhibited a 96-97% loss of cilia along the tracheal epithelial border, compared with only a 4-5% loss in controls. Infected poults receiving niacin in the drinking water exhibited only a 61.0% and 76.0% loss of cilia at doses of 70 mg/liter and 280 mg/liter, respectively. The results indicate that niacin treatment may influence the pathogenicity of B. avium infection.}, number={4}, journal={AVIAN DISEASES}, author={YERSIN, AG and EDENS, FW and SIMMONS, DG}, year={1991}, pages={674–680} }

Liver tryptohan 2,3-dioxygenase (TPO) activity was depressed significantly by the Bordetella avium infection localized in the trachea of the turkey poult. 2. Tryptophan, given orally, induced a significant increase in TPO activity in both control and infected poults. 3. Hydrocortisone induced TPO activity in the turkey in a dose dependent manner.}, number={4}, journal={COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY B-BIOCHEMISTRY & MOLECULAR BIOLOGY}, author={YERSIN, AG and EDENS, FW and SIMMONS, DG}, year={1990}, pages={755–759} }
