Ium (unpublished data). In summary, comparisons of physiological performances and gene expression profiles between different species of coral hosts per se will be available by preparing freshly bleached aposymbiotic coral with the menthol protocol combined with nutrient supplementation if necessary. This technique will also potentially benefit the search for a generalist coral to re-establish symbiosis with different heterogenic Symbiodinium, which will make the contributions of different Symbiodinium subclades to coral symbiosis more straightforward.AcknowledgmentsThe authors would like to thank members of the Coral Reef Evolutionary, Ecology and Genetics (CREEG) Group, Biodiversity Research Center, Academia Sinica (BRCAS) for field support.

Vaccines are the most effective means to control infectious diseases of humans and animals. The overwhelming majority of vaccines have been developed by one of two means: the pathogen is killed, and thus unable to establish infection, or a live attenuated strain of the specific pathogen is used to establish transient infection but without disease. While these classic approaches have been used successfully to prevent disease, there remain numerous bacterial, viral, and parasitic pathogens for which these approaches have not been successful. Identifying the specific antigens required for immunity has been an overarching goal in vaccine discovery and development over the past 30 years. Identification of specific antigens and associated mechanisms of immunity offers the promise of focusing the immune response on the key targets as well as developing lower-cost vaccines in which the specific required component is produced synthetically. There has beensuccess: the development and use of the Haemophilus influezae type B vaccine, composed of a specific polysaccharide antigen and a protein conjugate, has reduced H. influenza meningitis in the United States by 98 and has had similar impact in other countries where childhood vaccination has become routine [1]. The availability of complete genome sequences of pathogens and the linkage of genome data to higher throughput proteomic and immunologic approaches has accelerated the identification of the full set of possible antigens involved in protective immunity [2]. We have pursued these approaches for Anaplasma marginale, a bacterial pathogen of wild and domestic ruminants, which causes severe livestock losses, especially in sub-tropical and tropical regions worldwide, and also serves as a model for related rickettsial diseases of humans [3],[4]. Importantly, while immunization with GHRH (1-29) purified outer membranes induces significant buy Lixisenatide protection against bacteremia in replicate trials, protection is both variable among vaccinates, with some animals being completely protected againstSubdominant Bacterial Antigensinfection and others poorly protected [5],[6],[7]. Consequently, we seek to identify antigens in the outer membrane immunogen associated with protection and to enhance the response to these specific antigens with the goal of providing more uniform protection. The A. marginale surface is characterized by the presence of two highly abundant and closely related outer membrane proteins Major Surface Protein 2 (Msp2) and 3 (.Ium (unpublished data).
