ABSTRACT

Aim: Paenibacillus larvae subsp. larvae is the etiological agent of American foulbrood (AFB), the most virulent bacterial disease of honey bee brood worldwide. In many countries, AFB is a notifiable disease since it is highly contagious, in most cases incurable, and able to kill affected colonies. The aim of this study was to determine the prevalence of P. larvae subsp. larvae in Kurdistan province apiaries by polymerase chain reaction (PCR) technique.

Materials and Methods: A total of 100 samples were randomly purchased from apiaries in Kurdistan, Iran. Apiaries were randomly sampled in accordance with the instructions of the veterinary organization from different provinces and were tested using PCR method and an exclusive primer of 16S rRNA for the presence of P. larvae subsp. larvae.

Results: The results of this study indicated a low level of contamination with P. larvae subsp. larvae in the Kurdistan province. The number of positive samples obtained by PCR was 2%.

Conclusion: Therefore, monitoring programs for this honeybee disease in Kurdistan should be developed and implemented to ensure that it is detected early and managed.
