“…The literature suggests that philometrid nematodes can have profound detrimental effects on fish (Bauer et al, 1969;Paperna & Zwerner, 1976;Moravec & Dykova, 1978;Sinderman, 1987;Moravec, 1994Moravec, , 2004aMoravec, , 2006Kaall et al, 2001;Wang, 2002;Moravec et al, 2003). In particular, parasites of the genus Philometroides have been associated with disease in a range of freshwater fish species.…”

Seasonal development and pathological changes associated with the parasitic nematodePhilometroides sanguineusin wild crucian carpCarassius carassius(L.) in England

Pathological changes associated with the parasitic nematode Philometroides sanguineus (Rudolphi, 1819) are described for the first time from observations of infections in wild crucian carp Carassius carassius (L.) in England. The damage caused by P. sanguineus was influenced strongly by host size, parasite development and the seasonal migrations of female nematodes within host tissues. Male and unfertilized female nematodes located on the swim-bladder wall caused only minor, localized changes. In contrast, the migration of gravid female nematodes into the fins during autumn provoked an acute inflammatory response comprising neutrophils, eosinophils and lymphocytes. This was accompanied by fin distortion, swelling of the dorsal and caudal tissues, degenerative changes and localized oedema. The encapsulation of female nematodes in connective tissue throughout winter limited additional tissue damage. The emergence of gravid nematodes from the fins in spring to facilitate larval dispersal caused necrosis, hyperplasia and loss of skin integrity. This activity was again accompanied by acute inflammatory reactions. Pathological changes were more severe in crucian carp measuring less than 60 mm in length, with no signs of debilitation in larger fish. These observations suggest that any impact of P. sanguineus is strictly seasonal and may be limited to fry. Lesions caused by this parasite, only recently recorded in Britain, may represent an additional pressure upon wild crucian carp populations already threatened by hybridization, competition and habitat loss.

“…Recently, it has been farmed as a commercially important fish species. The catfish is carnivorous (Du, 1963), and it has been found to harbor many species of parasites (Yu et al, 1993;Wang et al, 2001;Wang, 2002;Moravec and Nie, 2002;Moravec et al, 2003), some of which are harmful and cause mortality (Yu et al, 1993). For diagnostics, prevention, and therapy of the parasite diseases, occurrences of some of the parasites in different sites of the fish have been studied.…”

“…In the urinary bladder, seasonal dynamics and distribution of the digenean Phyllodistomum pawlovskii were reported, and the results suggested that P. pawlovskii has little effect on the population structure of the yellowhead catfish (Li et al, 2005). Around the eyeball, the nematode Philometroides fulvidraconi caused inflammation and engorgement of the catfish (Wang, 2002). However, the intestinal parasites of P. fulvidraco previously have not been studied.…”

The frequency distribution and seasonal changes of intestinal helminths in Pelteobagrus fulvidraco were investigated from February 2001 to July 2002 in Liangzi Lake in the floodplain of the Yangtze River, central China. Four parasite species were found: the cestode Gangesia pseudobagri and the digeneans Orientocreadium siluri, Coitocoecum plagiorchis, and Echinoparyphium lingulatum. There was a significant difference in the mean abundance of O. siluri between male (8.12 6 16.99) and female hosts (3.19 6 5.42). Parasite distribution patterns were all overdispersed (s 2 /x . 1) and followed the negative binomial distribution. In the analysis of changes in mean parasite abundance and variance to mean ratio with host age, convex curves were observed for G. pseudobagri and O. siluri. This suggests that these 2 helminths may have had deleterious effects on the hosts. Significant seasonal changes were detected in the prevalence and mean abundance of the 4 helminths other than for the prevalence of O. siluri. The mean abundance of O. siluri, C. plagiorchis, and G. pseudobagri reached a peak in the spring, and E. lingulatum had the highest infection levels in the spring and early summer.

“…While under aquarium culture conditions, this nematode can also carry out a direct life cycle without the intermediate host (Stumpp 1975;Levsen and Jakobsen 2002). Nematode parasites are important pathogens that can result in evident pathological symptoms to their fish hosts, e.g., Philometroides fulvidraconi in the bullhead catfish, Pseudobagrus fulvidraco (Richardson) (Wang 2002). C. cotti attaches itself to the wall of the gastrointestinal tract of fish hosts by its buccal capsule, feeding on host blood or tissue fluid.…”

Two thousand four hundred fifty-eight fish comprised of 53 species were captured in the Danjiangkou Reservoir, in the northwestern part of Hubei Province, central China during 2004, to examine Camallanus cotti infections. We found that 19 cypriniform, 3 siluriforme, and 4 perciforme fishes were infected by the nematode. Our study revealed the species, Hemiculter bleekeri bleekeri, Culter oxycephaloide, Pseudolaubuca sinensis, Acanthobrama simony, Mylopharyngodon piceus, Ctenopharyngodon idella, Gnathopogon imberbis, G. argentatus, Saurogobio dabryi, S. dumerili, Gobiobotia ichangensis, Liobagrus marginatoides, and Ctenogobius shennongensis as new hosts of the worm. The number and range of fish host species found in this survey were much greater than any of the previous investigations. The mean prevalence, prevalence, mean abundance, and intensity of infection varied in different fish species, indicating a possible host preference. Moreover, we suggest that this nematode is a native parasite of cypriniform fishes in China, perhaps initially in the reaches of the Yangtze River.
