“…Studies on cases of heavy infection have demonstrated negative effects of metacercariae on fish host growth and stored lipid supplies, which impact over-winter survival (Lemly and Esch, 1984;Coleman and Travis, 1998;Johnson and Dick, 2001;Collyer and Stockwell, 2004). In contrast, other studies reported a lack of effects of metacercariae on fish condition and survival (Ballabeni, 1994;Ondrackova et al, 2004). In the present study, we only detected a negative relationship between Prosorhynchus spp.…”

Little attention has been paid to flatfish parasitism as a potential factor of variation in year-class strength. The aim of this study was to evaluate the relationship between parasitic infection and nutritional condition of young-of-year (YOY) common sole. Sole were collected monthly from May (early settlement) to November 2004 in a mussel pole culture area, using a push-net or a trawl, and dissected for parasite identification and counts. Total lipids were extracted from the whole body and lipid classes quantified. Triacylglycerols to sterols (free form) ratio (TAG/ST) was used as an index of nutritional status. Digenean metacercariae infection, characterized by two dominant genera, displayed clear seasonal dynamics and the highest records yet reported for sole. Prevalence (P%) and mean abundance (Ab ± SE) increased for Timoniella spp.

“…The European minnow ( Phoxinus phoxinus ) is a cyprinid occurring in most European freshwater systems. Local adaptation in growth and survival of P. phoxinus to a specific pathogen, the trematode Diplostomum phoxini , has been highlighted in the early 1990′s (Ballabeni and Ward ; Ballabeni ). Little is known about the influence of bacterial pathogens on this species' immunogenetics, especially on patterns of genetic structure and polymorphism at MHC loci.…”

Host-pathogen interactions are a major evolutionary force promoting local adaptation. Genes of the major histocompatibility complex (MHC) represent unique candidates to investigate evolutionary processes driving local adaptation to parasite communities. The present study aimed at identifying the relative roles of neutral and adaptive processes driving the evolution of MHC class IIB (MHCIIB) genes in natural populations of European minnows (Phoxinus phoxinus). To this end, we isolated and genotyped exon 2 of two MHCIIB gene duplicates (DAB1 and DAB3) and 1′665 amplified fragment length polymorphism (AFLP) markers in nine populations, and characterized local bacterial communities by 16S rDNA barcoding using 454 amplicon sequencing. Both MHCIIB loci exhibited signs of historical balancing selection. Whereas genetic differentiation exceeded that of neutral markers at both loci, the populations' genetic diversities were positively correlated with local pathogen diversities only at DAB3. Overall, our results suggest pathogen-mediated local adaptation in European minnows at both MHCIIB loci. While at DAB1 selection appears to favor different alleles among populations, this is only partially the case in DAB3, which appears to be locally adapted to pathogen communities in terms of genetic diversity. These results provide new insights into the importance of host-pathogen interactions in driving local adaptation in the European minnow, and highlight that the importance of adaptive processes driving MHCIIB gene evolution may differ among duplicates within species, presumably as a consequence of alternative selective regimes or different genomic context.

“…However, an increased growth of parasitized fish have been informed in several studies, especially related to cestodes parasites (Arnott et al 2000;Museth, 2001;Loot et al, 2002). In digenean larvae infected fishes, increased growth has only been recorded in the Cyprinidae Phoxinus phoxinus (Linnaeus, 1758), with this effect disappearing in high infections (Ballabeni, 1994).…”

Prevalence and intensity of black-spot disease in a fish community from a subtropical stream (Santa Lucía river basin, Uruguay)The objective of the present study was to identify fish species susceptible to black spot disease, the temporal variation in intensity prevalence and abundance of black spot, and its correlation with environmental and host parameters. In order to do so, several sampling campaigns were conducted bimonthly during one year, along the main course of an agricultural watershed. A total of twenty-seven fish species were collected, out of which only two, Astyanax aff. fasciatus ("mojarra") and Oligosarcus jenynsii ("dientudo") presented black spot disease. In A. aff. fasciatus, 63 % of black spot prevalence was registered and did not show significant seasonal changes during the sampling period, nor did the abundance and intensity. Regarding possible relations between the disease and environmental and host parameters, a higher intensity of black spot infection was observed in the ventral region of the fish and allometric coefficient (W T − L S , relationship) values did not differ significantly between parasitized and non-parasitized fish groups.
