Abstract

The present study was carried out during summer season of 2017 in a private apiary located in sefyta village at Sharkia Governorate to investigate the  effect of three antibiotics applied in different methods to control the American foulbrood disease(AFB) caused by  Paenibacillus larvae.
Obtained results cleared that the most potent  antibiotic used to control AFB was tylosin which showed the  highest efficiency when used  in powdered  sugar as it  resulted in the highest  reduction percentage in the  numbers of infected cells, being insignificantly differed as compared to rifampcine  in powdered  sugar. On the other hand, the antibiotic oxytetracycline  showed the least efficiency. Control colonies showed an increase in the number of infected cells.
Conclusively, Tylosin was the most effective antibiotic used in controlling American foulbrood disease when it used in the powdered sugar methods  in decreasing  the number of infected cells  where  the average number of infected cell decreased from183.33 before treatment to 10.00 after the 4th treatment and in the reduction percentage, where its reduction percentage was 96.47%.
