Intracellular endosymbiotic bacteria are common and can play a crucial role for insect pathology. Therefore, such bacteria could be a potential key to our understanding of major losses of Western honey bees (Apis mellifera) colonies. However, the transmission and potential effects of endosymbiotic bacteria in A. mellifera and other Apis spp. are poorly understood. Here, we explore the prevalenc...

background: the aim of this study was to determine the prevalence of the nosema ceranae and nosema apis among apiaries using both spore counts and multiplex pcr and the replacement of n. apis by n. ceranae in some regions of turkey. methods: a hundred honey bee samples were collected from 99 apiaries in 11 different locations in 2011-2012 in turkey. nosema infection degree from collected sample...

The use of urban green spaces, including gardens, in pollinator conservation initiatives, excites significant public interest but advice on effective plants frequently relies qualitative data. This study considered responses to specific nectar sugar characteristics determine if they offer the potential for selection candidate plants. Pollinator feeding 60 plant species at National Botanic Garde...

Nosema apis and ceranae are dangerous parasites of the honey bee (Apis mellifera). N. is more pathogenic and, nowadays, widespread than apis. There also cases mixed infections or only Both can lead to weakening death A. mellifera colonies. It crucial make a fast reliable diagnosis monitor disease start correct treatment. Additionally, there need for further research on pathogenicity spp. their ...

Natural honey is an ancient remedy in folk medicine around the world particularly where conventional and modern therapeutic agents fail. Here we report antibacterial potential of a number of unifloral and multifloral natural honey samples produced in Pakistan. Honey samples were collected from colonies of Apis mallifera and Apis cerana bees foraged on Acacia modesta, Plactranthus speices, Zizip...

Nosema spp. fungal gut parasites are among myriad possible explanations for contemporary increased mortality of western honey bees (Apis mellifera, hereafter honey bee) in many regions of the world. Invasive Nosema ceranae is particularly worrisome because some evidence suggests it has greater virulence than its congener N. apis. N. ceranae appears to have recently switched hosts from Asian hon...

Honeybees, Apis spp., maintain elevated temperatures inside their nests to accelerate brood development and to facilitate defense against predators. We present an additional defensive function of elevating nest temperature: honeybees generate a broodcomb fever in response to colonial infection by the heat-sensitive pathogen Ascosphaera apis. This response occurs before larvae are killed, sugges...

The objective of this study was to compare the effectiveness of the multiplex PCR method and traditional light microscopy in identifying and discriminating the species of Nosema spp. spores in worker bees from winter hive debris in the Province of Warmia and Mazury (NE Poland). A total of 1000 beesdead after from the bottom of the hive from bee colonies were analyzed. Spores were identified wit...

Gilliamella apicola and Snodgrassella alvi are dominant members of the honey bee (Apis spp.) and bumble bee (Bombus spp.) gut microbiota. We generated complete genomes of the type strains G. apicola wkB1(T) and S. alvi wkB2(T) (isolated from Apis), as well as draft genomes for four other strains from Bombus. G. apicola and S. alvi were found to occupy very different metabolic niches: The former...
