Gyrodactylus thymalli and G. truttae infecting grayling (Thymallus thymallus) and brown trout (Salmo trutta) in Austrian rivers.
Vis sammendrag
In the course of the presented study 413 grayling (Thymallus thymallus) and 89 brown trout (Salmo trutta) were collected from 29 localities belonging to 15 Austrian watercourses, all within the Danube drainage system, and investigated for infection with monogenean Gyrodactylus. A total of 41 grayling (9.9 %) and 80 brown trout (89.9%) showed an infection. Sequencing of the internal transcribed spacer (ITS) regions 1 and 2 of the nuclear ribosomal DNA (rDNA) cluster was used for species identification of 92 collected Gyrodactylus specimens. Three species were detected; of the 49 parasites from grayling 32 were identified as G. thymalli/G. salaris (65.3%), 11 as G. truttae (22.5%), and 6 as G. teuchis (12.2%). Of the 43 Gyrodactylus individuals sampled from brown trout 3 turned out as G. thymalli/G. salaris (7%), 25 as G. truttae (60.5%), and 13 as G. teuchis (32.5%). Trout infections frequently exceeded 30 Gyrodactylus specimens per fish, whereas for grayling there was a maximum of 3 parasite individuals per fish. In several cases, a host population of a particular sampling locality was infected with different Gyrodactylus species, whereas mixed infections of particular host individuals were rarely observed.
For 35 G. thymalli specimens 745 bp long sequences of the mitochondrial cytochrome oxidase subunit 1 (COI) gene were determined. These sequences represented 10 new haplotypes that group into at least 2 well supported clades in phylogenetic analyses using all currently known mitochondrial haplotypes of G. thymalli/G. salaris. The two new clades show average K2P distances of 0.01-0.031 to all other previously described clades. None of the 4 different phylogenetic approaches, i.e. Neighbor-joining, Maximum, parsimony, Maximum likelihood, and Bayesian inference, could resolve the basal internal nodes with high statistical support. Thus, the G. thymalli parasites from the Danube included in the current study do not provide support for the hypothesis that the Danube basin served as a glacial refugium for Northern European G. thymalli/salaris.

MONODB: FIRST STEPS IN THE PROVISION OF A CENTRALISED WEB-BASED RESOURCE FOR THE MONOGENEA.
Vis sammendrag
A number of biologists have independently gathered together and made publicly available, information relating to the monogenean genera known in their time. Of these, Yamaguti’s Systema Helminthum, produced over 40 years ago, remains the first point of reference for many helminth researchers. In terms of existing web-based resources, whilst there are a number of sites specialising in particular genera or regional fauna, there are very few that have tried to synthesise current knowledge concerning the Monogenea. Given the lack of such a synthesis, basic taxonomic and biological information concerning the numerous known monogenean genera is frequently difficult or impossible to access, often being published in grey literature or inaccessible journals, which may be beyond the reach of researchers with limited budgets or informational resources. Even when such data are available, images and descriptions of taxonomically informative traits are of variable quality. This paper describes the development of a web-based resource, the steroid enhanced big sister of “GyroDb”.
We have started to construct a web site, the eponymously named “MonoDb”, which will provide access to records for recognised (and retired?) monogenean genera. In addition to overviews of monogenean biology, taxonomy and relevant research techniques written by acknowledged experts (any takers?), access will be provided to individual species records arranged by family and genus. Each species record will comprise images and molecular data relevant to their taxonomic identification, original references for descriptions and other key information e.g. host and habitat etc. For type species and other important species or species groups, the site will contain authored reviews of current biological and systematic knowledge. In the future we intend the site to allow users to submit new data which will be refereed to ensure quality and consistency before upload to the publicly accessible databases. It is intended that the site be accessible for users of all backgrounds and interests including both those with a casual interest in monogeneans and established researchers. Links to relevant sites such as FishBase and researcher and facility homepages will also be provided. A provisional version of MonoDb may be accessed at www.MonoDb.net.

Increased survival to Gyrodactylus salaris infections demonstrated by family selection in a Norwegian Atlantic Salmon (Salmo salar) population.
Vis sammendrag
Since the introduction of Gyrodactylus salaris Malmberg into Norwegian salmon rivers in the mid-1970s 46 populations have been infected. Gyrodactylosis caused by G. salaris is a major notifiable disease with a risk of further trans-national spread. The national strategy is to eradicate the parasite by use of rotenone. The strategy has been successful in some small rivers but has failed in all larger infected river systems. Alternative strategies are thus clearly needed. Genetic selection for increased resistance to G. salaris has not been investigated until now. We estimated additive genetic variation and heritability of survival in a pedigreed family material of Atlantic salmon parr subjected to a controlled challenge test with G. salaris. To obtain the family material eggs were fertilized in a hierarchic mating design to produce 49 full-sib groups of salmon within 25 paternal half-sib groups. When reaching an average size of 8 g progeny (n = 973) were challenged with G. salaris and the test was run until mortalities stopped. Dead fish were removed daily and together with the survivors, DNA fingerprinted for family identification.
Mortalities started after ca. 15 days, peaked at around day 45 at a level of ca. 50 individuals, declined sharply and leveled out close to zero. Only 11.3 % of the 973 salmon survived the test, but the course of mortality varied significantly between full-sib families. In eleven of the 49 full-sib families all fish died, whereas the 4 least affected families had survival rates between 36-48%. Estimated heritability of survival (on the liability scale) was 0.32 ± 0.10. Time until death and the ability to survive were not expressions of the same genetic trait. Selecting survivors as parents for the next generation for restocking is expected to improve the overall survival rate significantly and can be used as a disease control measure to contain the infection at a level where the parasite ceases to be a major problem.

Resident Arctic charr (Salvelinus alpinus) is a suitable host for sustained Gyrodactylus salaris (Monogenea) infections in southern Norway.
Vis sammendrag
Anadromous Arctic charr (Salvelinus alpinus) and sympatric Atlantic salmon (Salmo salar) have both been found infected with G. salaris in some river systems in North Norway. In the present study we explore the potential of resident Arctic charr as host and reservoir for G. salaris in the absence of Atlantic salmon. Arctic charr were sampled with gill nets in nine lakes from four water currents in southern Norway, fixed in ethanol and screened for Gyrodactylus under a stereomicroscope. Gyrodactylus were found on Arctic charr in five lakes. In four of these lakes (upstream the anadromous stretches of Numedalsvassdraget) G. salaris was identified by means of both molecular markers and morphology. The infection has persisted through years (2000-2005) in at least one of these localities (Lake Pålsbufjorden). This locality was sampled in August and on the spawning grounds in October 2005. Both prevalence and abundance of Gyrodactylus was highest in October. In addition, prevalence, abundance and mean intensity of parasites was higher in males than in females. A more detailed study of the distribution of G. salaris in Arctic charr cohorts (2-7 year) in October revealed a positive correlation between age and prevalence. The finding of G. salaris in four lakes, and the persistence and relative high levels of the infection in Pålsbufjorden, indicates that Arctic charr is able to sustain an infection without sympatric Atlantic salmon.

Transmission of Gyrodactylus salaris (monogenea: gyrodactylidae), with emphasis on dead hosts as a reservoir of infection.
Vis sammendrag
Economically, one of the most important platyhelminths to have successfully invaded novel fish populations is Gyrodactylus salaris. This ectoparasitic monogenean has devastated stocks of wild Atlantic salmon in Norway since its introduction from the Baltic during the 1970s. The parasite with its high fecundity and transmission potential can rapidly colonize an entire river system. Having no specific transmission stage, G. salaris utilizes four different routes of transfer to new hosts: via contact with live hosts, via dead hosts, by detached parasites drifting in the water column, and by parasites attached to the substrate. However, the relative importance of these different routes is largely unknown. In the current study, we evaluate the transmission strategies of G. salaris focusing on the importance of dead hosts, by assessing the survival and infectivity of detached worms and those removed from dead hosts. At 18oC, survival off the host is 1d, but at 3oC parasites survive for 4d. Surprisingly, however, most parasites remain with their host following its death. Such worms survive despite being wrapped in decaying host tissue, their life span being doubled compared with individuals maintained in vitro, probably sustained by feeding on the dead host. G. salaris can actually survive for up to 6d at 12oC on a dead host and, importantly, are still infectious, at least up until 72h post-host death. This survival strategy is in stark contrast to that previously observed for individuals of G. turnbulli in which parasites actively leave a dead host. For G. salaris, dead hosts may serve as an important infection source. In these experiments, worms were also aged to determine whether transmission was influenced by life span. It appears that worms that have given birth are more likely to transfer to a new host than those that have not given birth. Thus, although having no specific transmission stage, gyrodactylids apparently do display a non-random timing of transmission. The present results highlight the importance of dead hosts as a significant reservoir of infection. Taken the significant threat that G. salaris constitutes to populations of Atlantic salmon, this is an aspect which should be incorporated into future management polices and risk assessments.
