American foulbrood disease has a major impact on honeybees (Apis melifera) worldwide. It is caused by a Gram-positive, spore-forming bacterium, Paenibacillus larvae. The disease can only affect larval honeybees, and the bacterial endospores are the infective unit of the disease. Antibiotics are not sufficient to combat the disease due to increasing resistance among P. larvae strains. Because of...

American foulbrood is a disease of larval honeybees (Apis mellifera) caused by the bacterium Paenibacillus larvae. Over the years attempts have been made to develop a selective medium for the detection of P. larvae spores from honey samples. The most successful of these is a semiselective medium containing nalidixic acid and pipermedic acid. Although this medium allows the growth of P. larvae a...

Volume 1, no. 6, e00668-13, 2013. The species infected by the five bacteriophages was misidentified as Paenibacillus larvae. The article title should read as given above, and the organism identified as Paenibacillus larvae should be identified as Brevibacillus laterosporus throughout. Page 1: The abstract should read as follows. “Brevibacillus laterosporus is a secondary invader following Europ...

The minimal inhibitory concentrations (MICs) of tylosin were determined to 67 strains of Paenibacillus larvae subsp. larvae, the causal agent of American Foulbrood (AFB) disease, from different geographical origins. MIC values obtained ranged from 0.0078 to 0.5 microg/ml. These very low values imply that no resistance to tylosin was found in any isolate of the Foulbrood pathogen. The measuremen...

Background: Paenibacillus larvae is the etiological agent of American foulbrood (AFB) disease, the most lethal disease in honeybee (Apis mellifera) larvae. Aims: The aim of the present work was to study the antimicrobial effect of cell free supernatant (CFS) of probiotics on an Iranian isolate’s biofilm formation. Methods: A l...

Introduction American Foulbrood (AFB) is one of the most threatening epidemic brood diseases in honey bee colonies. This disease is caused by the pathogen Paenibacillus larvae larvae. According to the common animal health law in Germany the outbreak of AFB has to be reported to veterinarian service. The veterinarian has to decide about eradication of bee colonies, cleaning and disinfection as w...
