In Advances in Entomopathogenic Nematode Taxonomy and Phylogeny the numerous species of Steinernema and Heterorhabditis described since the previous volume, published in 2007, are evaluated and discussed. Valid species proposed from 2007-2015 are covered in detail, each taxon having an illustrated diagnostic description and additional data on molecular characterisation, distribution and biology, etc. An addendum gives brief details of species proposed during 2016. An overview of the taxonomy of the two families provides an up-to-date list of species for both genera, including new synonyms and detailed commentary on specific status where appropriate. Tabular keys to all valid species of Steinernema and Heterorhabditis assist in diagnostics. A chapter on phylogeny and phylogeography completes the book.

The volume deals with morphology, taxonomy and systematics of entomopathogenic nematodes (EPN) in the families Steinernematidae and Heterorhabditidae and bacteria associated with these nematodes. In the first part, history, taxonomic status, family and genus definitions of EPN are mentioned. In the second part, all useful aspects of morphology and methodology of EPN are mentioned with illustrations and SEM photographs and instructions on how to make the measurements, and how to use them in taxonomic work. A polychotomous key with SEM photographs and illustrations is provided. In the third part, full descriptions of all species are presented with latest information about each species. In the fourth part, molecular and phylogenetic methods for working with EPN are presented, including the latest information and instructions on how to use molecular data in taxonomic work. In the last part, bacteria associated with this group of nematodes are discussed in the context of the latest information about methodology, biology and taxon.

Plant-parasitic and free-living nematodes are increasingly important in relation to food security, quarantine measures, ecology (including pollution studies), and research on host-parasite interactions. Being mostly microscopic, nematodes are challenging organisms for research. Techniques for Work with Plant and Soil Nematodes introduces the basic techniques for laboratory and field work with plant-parasitic and free-living soil-dwelling nematodes. Written by an international team of experts, this book is extensively illustrated, and addresses both fundamental traditional techniques and new methodologies. The book covers areas that have become more widespread over recent years, such as techniques used in diagnostic laboratories, including computerized methods to count and identify nematodes. Information on physiological assays, electron microscopy techniques and basic information on current molecular methodologies and their various applications is also included.

Exploration in Laboratory Animal Sciences Understanding Life Phenomena updates our knowledge about the newer technologies such as molecular biology, genomics including sequencing, proteomics, transcriptomics, cell culture, stem cell culture, transgenesis and their translation to understand systematics and phylogeny of laboratory animals at molecular level. In seven sections Exploration in Laboratory Animal Sciences Understanding Life Phenomena resolves issues of conservation, applications in environment monitoring, production of drugs and others. Comparative research has enabled use of domestic animal models that translate the advances in basic biosciences to the schemes for human welfare including medicine. Molecular geneticists are unravelling the complexities of mammalian genes and the field of biotechnology is maturing at a fast pace. Additionally, research focused on immunology and animal behavior offer new insight into ways of enhancing animal welfare. The rise in consumption of animal proteins in addition to the challenges of sustaining our natural resources has given animal scientists a vast array of opportunities to engage in integrative systems-based research for meeting the challenges that behold us. Exploration in Laboratory Animal Sciences Understanding Life Phenomena also discusses the manipulation of animals as factories for the production of safe foods, drugs, and sensors and others to meet the contemporary challenges faced by mankind in the new world order created by pandemic of Covid 19. It also includes several chapters on the causation and management of certain diseases and impact of microbes on life. Provides insight to newer and futuristic technologies to understand disease process and drug design by animal models Addresses a wide variety of species and covers a wide variety of topics (such as animal species, the laboratory setting, regulatory guidelines, and ethical considerations) to fully prepare for work with all types of animals Gives a perspective on laboratory animal use that allows to explain the benefits of animal use as required by veterinary technology program accreditation procedure Includes examples of animal bio-technological techniques (including stem cell and tissue engineering) for their applications to humanity Offers new insight into ways of enhancing animal welfare by the inclusion of research results focused on immunology and laboratory animal behavior

The insect!1 remain in symbiotic associations with a tremendous number of microorganisms, and some of them could be classified as parasitic/pathogenic. Without question, insect pathogens act as natural mortality agents and represent the third leg of the triad of biological control which is an environmentally sound alternative to chemical control. The virulence and pathogenicity of an insect parasite i. e. disease agent are determined by the microbial genome as a result of the coordinated expression of a concert of genes. These genes may be organized as cassettes and be associated with transmissible DNA. The acquisition of these domains or pathogenicity islands, may be sufficient to develop a transgenic virulent pathogen. The insect pathogens are very specific and this property can be exploited in making insects sick. However, rarely have field applications of highly virulent strains of viruses, fungi, bacteria, protozoa resulted in massive insect population reductions or induced widespread, persistent epizootics as the same is also governed by host susceptibility regulated by genetics, age, sex and physiological state of the host. Insect pathogens causing acute or chronic diseases must be able to persist in the environment, to multiply in the host, and to spread to other susceptible hosts. In this book, I have attempted to bring together all recent studies regarding both fundamental and more applied research aspects related to entomopathogens, bacteria, viruses, fungi and nematodes in order to facilitate their development and commercial exploitation.
