Apoptosis is not only pivotal for development, but also for pathogen defence in multicellular organisms. Although numerous intracellular pathogens are known to interfere with the host's apoptotic machinery to overcome this defence, its importance for host-parasite coevolution has been neglected. We conducted three inoculation experiments to investigate in the apoptotic respond during infection ...

We evaluated the performance of six named types of package honey bees, Apis mellifera L (Hymenoptera: Apidae), from four commercial producers. We examined the effects of levels of the parasitic mite Varroa destructor Anderson & Trueman, the endoparasitic mite Acarapis woodi (Rennie), the gut parasite Nosema (species not determined) in samples from bees in 48 packages, and levels of adult drones...

The honey bee, Apis mellifera L., is host to a variety of microorganisms. The bacterial community that occupies the adult worker gut contains a core group of approximately seven taxa, while the hive environment contains its own distribution of bacteria that is in many ways distinct from the gut. Parasaccharibacter apium, gen. nov., sp. nov., is a hive bacterium found in food stores and in larva...

The trypanosome Lotmaria passim and the microsporidian Nosema ceranae are common parasites of the honey bee, Apis mellifera, intestine, but the nature of interactions between them is unknown. Here, we took advantage of naturally occurring infections and quantified infection loads of individual workers (N = 408) originating from three apiaries (four colonies per apiary) using PCR to test for int...

Bombus atratus bumblebees from Colombia that were caught in the wild and from breeding programs were screened for a broad set of bee pathogens. We discovered for the first time Lake Sinai Virus and confirmed the infection by other common viruses. The prevalence of Apicystis bombi, Crithidia bombi and Nosema ceranae was remarkably high. According to other studies the former two could have been c...

In New Zealand, the introduced honey bee (Apis mellifera) is a valuable production animal, providing pollination services for horticultural crops and significant export volumes of honey, especially mānuka honey. Honey bees in Zealand are free from number diseases pests such as European foulbrood, acarine disease, small hive beetle, Israeli acute paralysis virus tropilaelaps mites. We sought to ...

Beekeeping, performed in many parts of the world, has a very large place world trade market with bee products such as wax, venom, propolis and royal jelly, especially honey production. However, diseases are quite common restricted production products. One most important these diseases, Nosema, is caused by spores intestinal epithelium cells honeybee. Nosema apis ceranae factors this disease als...
