    Notes: : Diseases in wild fish populations may have multiple economic and social impacts. Epidemics of infectious diseases, which are associated with the presence of some microbe or parasite, have recently been observed in several major estuarine systems in the eastern United States. The most prevalent of these problems is ulcerative mycosis (UM), a fungal infection. The agents responsible for UM and many of these other diseases are opportunistic pathogens that are not believed to infect normal, immunocompetent individuals. While inroads have been made into determining the infectious agents associated with these diseases, we know very little of how pollution may influence their prevalence. Understanding the importance of pollution requires an awareness of all the environmental conditions that can affect the health of wild populations. In this paper, a multistep examination of the interactions between the host, pathogen(s), and environment is outlined.

    Notes: [Auszug] Antimicrobial peptides are increasingly recognized as a critical first line of defence against many pathogens and have been isolated from epithelial tissues and blood cells of many vertebrates, as well as from prokaryotes, plants and invertebrates. Here we show that 'piscidins', a previously ...

    Molecular Taxonomy of the Suborder Bodonina (Order Kinetoplastida), Including the Important Fish Parasite, Ichthyobodo necator (2002)

    Notes: . Ichthyobodo necator is an important fish ectoparasite with a broad host and ecological range. A novel method, involving the use of an anesthetic, allowed the collection of large numbers of parasites from the skin and gills of hybrid striped bass (Morone saxatilis male ×M. chrysops female). Genomic DNA from these samples was used to amplify and clone the 18S rRNA gene. The 18S rRNA gene was similarly cloned from Bodo caudatus, Bodo edax, Bodo saltans, an unidentified Bodo species, and Dimastigella trypaniformis. The resulting sequences were aligned with other representative kinetoplastid species using pileup and similarities in secondary structure. Phylogenetic relationships within the suborder Bodonina and representatives of the suborder Trypanosomatina were determined using maximum-likelihood statistics. The phylogenetic analyses strongly supported the order Kinetoplastida as a monophyletic assemblage consisting of at least two major lineages. One lineage consisted exclusively of 1. necator, indicating that it may represent a new suborder. The second lineage consisted of all other kinetoplastid species. This second lineage appeared to contain at least 8 bodonine sublineages, none of which correlated with currently recognized families. For three sublineages, there was a close correspondence between the 18S phylogeny and the classical taxonomy of Dimastigella, Rhynchobodo, and Rhynchomonas. In contrast, Bodo and Cryptobia were polyphyletic, containing species in two or more sublineages that may represent separate genera.

    Notes: [Auszug] The alga, which represents a new family, genus and species within the order Dinamoebales (K. Steidinger, personal com-munication), was inadvertently discovered by fish pathologists5 who observed sudden death of cultured tilapia (Oreochromis aureus and O. mossambica) several days after their ...

    Callinectin, an Antibacterial Peptide from Blue Crab, Callinectes sapidus, Hemocytes (1999)

    Notes: Abstract. This paper describes the isolation of an approximately 3.7 kDa, basic, antibacterial peptide (designated callinectin), which represents the major antibiotic activity in blue crab, Callinectes sapidus, hemocytes. A single-step purification using low-pressure cation-exchange chromatology yielded a highly purified (〉95%) peptide. Purity was confirmed by C4 reverse-phase high-performance liquid chromatography (RP-HPLC), native gel electrophoresis, sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE), capillary electophoresis, and mass spectral analysis. The partial amino acid sequence obtained via Edman degradation revealed no significant homology to other reported peptides in the Basic Local Alignment Search Tool (BLAST) program database.
