Background:  American foulbrood (AFB) is a bacterial brood disease of honey bees caused by the Gram-positive and spore-forming bacterium Paenibacillus larvae. The disease is transferred and initiated only by the spore stage of the bacterium. Young bee larvae are infected by spores, then the spores germinate in the gut of the larva and the vegetative form of the bacteria begins to grow, taking its nourishment from the larva. Infected larvae normally die after their cell is sealed. The vegetative form of the bacterium produces many millions of spores which may remain dormant for many years. P. larvae ERIC I and II are frequently isolated from brood of AFB-infected colonies or from honey samples. The fast killing genotypes ERIC III, IV and V are obviously less prevalent in the context of AFB outbreaks since they have not been isolated in the recent years.
​For the universal detection of AFB, independent of the ​Paenibacillus larvae​ genotype, ingenetix offers a separate real-time PCR Kit. ​

Description:  BactoReal® Typing Kit Paenibacillus larvae ERIC I is a real-time PCR for the qualitative detection of the plx1 gene of Paenibacillus larvae ERIC I. Our carefully designed primers and probe ensure highest sensitivity and specificity. The kit consists of an assay mix for the detection of the pathogen as well as a positive control and an internal positive control (IPC) system. To minimize PCR cross-contamination, the included reaction mix contains dUTP and uracil-N glycosylase (UNG).

  • PCR platforms: BactoReal® Typing Kit Paenibacillus larvae ERIC 1 was validated with the ABI® 7500 Fast Real-Time PCR System (fast cycle parameters are not supported, Thermo Fisher Scientific) and the QuantStudio™ 5 Real-Time PCR System (Thermo Fisher Scientific). It is also compatible with other real-time PCR instruments which detect and differentiate fluorescence in FAM and Cy5 channel (eg. QuantStudio™ 5/6/7 Real-Time PCR System (Thermo Fisher Scientific), qTOWER3G (Analytik Jena), Mic instrument (bio molecular systems), cobas z 480 Analyzer (Roche)).

    BactoReal®, MycoReal®, ParoReal® and ViroReal® Kits run with the same thermal cycling conditions.
