American foulbrood is the most destructive honeybee bacterial disease. The etiological agent, Paenibacillus larvae, has been classified into four genotypes by a repetitive-element PCR (ERIC I-IV) and 21 sequence types by multilocus sequence typing (ST1-21). In this study, we genotyped Japanese P. larvae isolates for the first time and revealed the presence of three genotypes (ERIC I-ST2, ERIC I...
Genome sequences offer a broad view of host-pathogen interactions at the systems biology level. With the completion of the sequence of the honey bee, interest in the relevant pathogens is heightened. Here we report the genome sequences of two of the major pathogens of honey bees, the bacterium Paenibacillus larvae (causative agent for American foulbrood disease) and the fungus Ascosphaera apis....
american foulbrood disease (afb) is one of the most important bacterial diseases of honey bee can be caused severe losses in apiaries. afb caused by paenibacillus larvae a gram positive and spore-forming bacterium. this study was taken placed in 15 area of east azerbaijan province of iran between 2006-2007 years. in this study, 500 bee hives were randomly selected from 100 apiaries. standard ba...
Paenibacillus larvae bacteriophage Tripp was isolated from an American foulbrood diseased honey bee hive in North Carolina, USA. The 54,439-bp genome is 48.3% G+C, encodes 92 proteins, no tRNAs, and has 378-bp direct terminal repeats. It is currently unique in Genbank.
american foulbrood (afb) is the most serious brood disease of the honey bee. traditional methods are reliable but rather slow simply because they are based on biochemical, morphological and physiological identification of cultivated isolates. the aim of this study is the detection of paenibacillus larvae larvae spores in honey and diseased larvae samples by culture and pcr. therefore 54 samp...
Virulence variations of Paenibacillus larvae subsp. larvae, the causative agent of American foulbrood disease of honeybees, were investigated by analysis of 16 field isolates of this pathogen, belonging to three previously characterized genotypes, as well as the type strain (ATCC 9545) of P. larvae subsp. larvae, with exposure bioassays. We demonstrated that the strain-specific 50% lethal conce...
Six sequenced and annotated genomes of Paenibacillus larvae phages isolated from the combs of American foulbrood-diseased beehives are 37 to 45 kbp and have approximately 42% G+C content and 60 to 74 protein-coding genes. Phage Lily is most divergent from Diva, Rani, Redbud, Shelly, and Sitara.
American foulbrood (AFB) disease is caused by the sporeforming bacterium Paenibacillus larvae larvae. Traditional diagnosis is based on culture technique is time and laboratory work consuming. In this study with standard strain, PCR was developed by specific primers and PCR products were electrophoresed on 0.8 % agarose gel. The PCR primers were selected on the basis of the 16S rRNA gene and am...
Worldwide, American foulbrood (AFB) is the most devastating bacterial disease of the honey bee (Apis mellifera). Because the distinction between AFB and powdery scale disease is no longer considered valid, the pathogenic agent has recently been reclassified as one species Paenibacillus larvae, eliminating the subspecies designations Paenibacillus larvae subsp. larvae and Paenibacillus larvae su...
