The host range of a bacteriophage is defined by what bacterial genera, species and strains it can lyse; it is one of the defining biological characteristics of a particular bacterial virus. Because of host factors such as masking by O antigens that affects injection and the presence of restriction endonucleases, the relative efficiency of plating (EOP), that is, the titer of the phage on a given bacterial cell line compared to the maximum titer observed, may vary considerably. This chapter describes rapid procedures for determining the host range and relative EOP on each host of any phage.

Donor-specific antibodies (DSAs) are essential causes of graft rejection in haploidentical hematopoietic stem cell transplantation (haplo-HSCT). DSAs are unavoidable for some patients who have no alternative donor. Effective interventions to reduce DSAs are still needed, and the cost of the current therapies is relatively high.

The nutria (Myocastor coypus) is a semiaquatic rodent that originally inhabited South America. However, the animals have spread to different continents as alien species, and their numbers are quickly increasing, especially in North America, Europe, and Eastern Asia including Japan. Although nutrias have been suggested to serve as reservoirs for pathogens, including parasites, there have been few reports on this subject.

Despite advancements in chronic arthritis treatment, there remains a significant demand for advanced nanotechnologies capable of efficiently delivering a wide range of therapeutic agents to provide symptomatic relief and facilitate the healing of inflamed cartilage tissue. Considering the significant impact of hypoxia on the development and maintenance of chondral tissue, replicating its effects on stem cells could be a potential approach for the treatment of osteoarthritis (OA). Cobalt is a prominent hypoxia-inducing agent, owing to its ability to activate the hypoxia-inducible factor (HIF) pathway regardless of cellular oxygen levels.

Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae) transmits many pathogens, including seven viruses, four protozoa and one nematode. This species has a wide distribution range across northern Afro-tropical, Palearctic, Australian, Indo-Malayan realms with a broad host spectrum, including cattle, buffaloes, sheep, pigs, dogs, horses and even humans. The heterogeneous nature of Culicoides' blood-feeding patterns is well documented, but the influence of various host blood meal sources on gut bacterial composition remains scant.

Maynard Smith's proposed two-fold cost of sex states that one of the disadvantages of clonal reproduction is the decreased ability to persist in dynamic ecosystems. However, the long-term persistence of some clonal alloploid lineages suggests that these lineages may not always be so ephemeral in nature. Understanding the stability of these lineages over time can inform our understanding of the advantages of an asexual mode of life.
