American foulbrood, caused by Paenibacillus larvae subsp. larvae (White 1906) is one of the most serious diseases of honey bees, causing beekeepers and health workers to make difficult, complex decisions and leading to the development of 'organic' treatments, such as grapefruit seed extract, with minor residue problems in the end product. This study evaluates the chemical composition of grapefr...

INTRODUCTION Paenibacillus larvae larvae (WHITE) is the causative agent of American foulbrood (AFB) in honey bees (Apis mellifera L.). This disease is lethal to honey bee colonies if curative control actions are not taken (HANSEN and BRØDSGAARD, 1997). Recently, increasing problems with AFB in Europe (DROBNÍKOVÁ,1992; HANSEN,1996; OTTEN, 1991; VON DER OHE et al. 1996) have renewed the interest ...

Paenibacillus larvae (P. larvae) is a pathogenic bacterium causing American Foulbrood Disease (AFB) in honeybee larvae. It necessary to develop alternative strategies for the control of this disease due serious colonies loses and use antibiotics. Recent studies are aimed at investigating natural fighting agents against P. In our study, it was demonstrate potential antibacterial efficacy ethanol...

Paenibacillus larvae is a Gram positive bacterium and the causative agent of the most widespread fatal brood disease of honey bees, American foulbrood (AFB). A total of thirty-three independent Paenibacillus larvae isolates from various geographical origins in North America and five reference strains were investigated for genetic diversity using multilocus sequence typing (MLST). This technique...

In the summer of 1997, larvae of the oriental beetle, Blitopertha orientalis, with milky disease were collected from a turf field in Chiba Prefecture, Japan. Characteristic footprint-shaped sporangia containing a spore and a parasporal body were isolated from the larval hemolymph. Examination of the bacteriological characteristics of this strain revealed that it was unable to grow in 2% NaCl, w...

objective: the orange-red spectrum of  the skin of  electric yellow (labidochromis caeruleus) is  one  of  the  idealistic and  necessary  schemas sought  by  aquarists  and commercial producers. in this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total l...

The gram-positive, spore-forming bacterium Paenibacillus larvae is the etiological agent of American Foulbrood (AFB), a globally occurring, deathly epizootic of honey bee brood. AFB outbreaks are predominantly caused by two genotypes of P. larvae, ERIC I and ERIC II, with P. larvae ERIC II being the more virulent genotype on larval level. Recently, comparative proteome analyses have revealed th...
