Book excerpt: Since the publication of the first edition of this book in 1982, investigation into the pathology of honey bees has progressed considerably. Furthermore, several different agents of disease, some newly discovered, have been causing increasing concern in recent years in many parts of the world. The book contains separate chapters on viruses, bacteria, fungi, protozoa, mites, nematode and insect parasites, non-infectious diseases, and the treatment of diseases. The contents are a thorough revision of the previous edition and incorporate much new information, especially with respect to viruses, bacteria, fungi, and mites. Specific organisms, such as the mite Varroa jacobsoni and the secondary diseases resulting from its presence, are considered in detail. Knowledge of the subject is central to well-managed beekeeping, an industry that, besides producing honey and wax for man, is increasingly valuable ecologically for pollinating wild as well as cultivated plants. Apart from its value for beekeeping and apicultural research, this book will also be of interest to ecologists, microbiologists, virologists, parasitologists, and general entomologists. - Serves as a thorough revision of the first edition - Focuses particular attention to new materials on viral diseases of bees, particularly the Varroa virus

Book excerpt: Honey -bee pathogens are spread worldwide and are strongly related to the decline of honey bee populations, with which has severe implications for beekeeping, honey production and ecology. Honey bee pathogens are continuously studied by researchers to with the aim to better understand the host--s-parasites relationship of these pathogens and the effects that they have on the bee coloniesy. Honey bee pathogens include bacteria (i.e. i.e., Melissococcus plutonius and Paenibacillus larvae), microsporidia (i.e. i.e., Nosema apis and Nosema ceranae), fungi (i.e. i.e., Ascosphaera apis), protozoa (i.e. i.e., Lotmaria passim, Crithidia bombi and Crithidia mellificae) and viruses (i.e. i.e., ABPV, CBPV, IAPV, KBV, DWV, BQCV and SBV). All of these pathogens are able to infect other bee species; infections would have with important implications in for their life cycles (e.g. e.g., Osmia sp. and Bombus sp.) or cause unknown epidemiological effects for other hymenopterans. BesidesIn addition, old and new invasive pests (such as Varroa destructor, Aethina tumida, Vespa velutina, etc.) necessitate more studies to definite define their role as possible vectors or possible sources of infection for honey bees. For these reasons, knowledge on honey -bee pathogens has become a matter of public interest and is connected with the critical role of honey -bee health. The aim of this Special Issue is to explore honey bee pathogens, considering any aspect in relation to host-pathogen interaction and highlighting the possible interaction and spillover with other bee species and invasive pests, through a series of research articles focusing that focus on different aspects of pathologies.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nosema disease in honey bees (Apis mellifera) is caused by either the microsporidium, Nosema apis or Nosema ceranae. It has been proposed that N. ceranae originated in east Asia as a pathogen of Apis cerana, and then spread worldwide infecting A. mellifera. To examine this, the genetic variation of N. ceranae samples from Vietnam, Iran, Ontario-Canada, Alberta-Canada, United States, Mexico and Argentina was investigated using novel genetic markers for this pathogen, simple sequence repeat (SSR) length polymorphisms and translation elongation factor-1 alpha sequence. Both markers showed that the highest genetic variation was in Vietnam, and the translation elongation factor-1 alpha sequence showed that only the most common genotype in Vietnam was detectable in other parts of the world. The SSR length polymorphisms also detected some variation in other parts of the world, which corresponded to the international movement of honey bee queens. The results are consistent with N. ceranae being an invasive species with a subset of N. ceranae genotypes spreading from southeast Asia. Several microbial-derived products were tested for their ability to induce innate immunity against nosema disease in A. mellifera. Feeding chitosan or peptidoglycan significantly reduced spore numbers and altered expression of the antimicrobial peptide genes, hymenoptaecin and defensin2, and the autophagy-related gene, blue cheese, of adult honey bees. A study on the effect of N. ceranae infection, as well as infection along with chitosan and peptidoglycan treatment revealed that hygienic behaviour of A. mellifera was not affected by infection or treatment. However, chitosan or peptidoglycan treatment stimulated foraging behaviour. Peptidoglycan and N. ceranae infection without treatment did not alter the proboscis extension reflex (PER), but chitosan significantly decreased memory retention on the first day, but not later days, of the PER test. Chitosan and peptidoglycan treatment also increased the survivorship compared to N. ceranae infection without treatment. Chitosan and peptidoglycan are promising alternative treatments for nosema disease, reducing pathogen reproduction, increasing longevity and stimulating foraging behaviour.
