“…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.…”

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.

“…However, recent detailed redescription of P. lateolabracis by Quiazon et al (2008), based on newly collected specimens (including males) from the type host from Japan, has shown that only the specimens from Lateolabrax japonicus (Lateolabracidae) belong to this species, whereas those reported from many other fish hosts represent rather different species. Subsequently, Moravec (2008) revalidated Philometra jordanoi, mentioning that the philometrids reported as P. lateolabracis from other European hosts Mycteroperca rubra and Seriola dumerili (see Moravec et al 2003, as well as those from the gonads of Epinephelus cyanopodus and E. fasciatus off New Caledonia (Moravec and Justine 2005), should be reported as Philometra sp. until new data are available.…”

Examinations of marine fishes off New Caledonia, South Pacific, carried out in [2003][2004][2005][2006], yielded some nematodes of the genus Philometra Costa, 1845, including the following three new species: P. cyanopodi sp. nov. (males and subgravid females) and P. lethrini sp. nov. (males and subgravid females) from the gonads of Epinephelus cyanopodus (Richardson) (Serranidae) and Lethrinus genivittatus Valenciennes (Lethrinidae), respectively, and P. lagocephali sp. nov. (gravid female) from the abdominal cavity of Lagocephalus sceleratus (Gmelin) (Tetraodontidae). Another congeneric species P. fasciati sp. nov. from the gonads of Epinephelus fasciatus (ForsskDl) (Serranidae), originally reported as P. lateolabracis (Yamaguti, 1935), has been established with reference to the description of males and a mature female published by Moravec and Justine (2005). The new species are characterized mainly by the length of spicules and the length and structure of the gubernaculum, structure of the male caudal end (except for P. lagocephali), body size, location in the host and by the types of hosts. In addition, Philometra sp. . Une autre espPce congénérique P. fasciati sp. nov., des gonades de Epinephelus fasciatus (ForsskDl) (Serranidae), originellement rapportée comme P. lateolabracis (Yamaguti, 1935), a été établie par référence B la description des mâles et d'une femelle mfre publiée par Moravec et Justine (2005). Les nouvelles espPces sont caractérisées principalement par la longueurs du spicule, la structure du gubernaculum, la structure de l'extrémité caudale du mâle (sauf pour P. lagocephali), la taille du corps, la position chez l'hôte et le type

“…On the other hand, some of these parasites are highly pathogenic and may be agents of serious diseases of fish with economic importance. A total of eight species of Philometra Costa, 1845 have so far been reported from marine fishes of the Mediterranean (including the Adriatic, Aegean, Ionian, Ligurian and Tyrrhenian Seas and the Sea of Crete): Philometra filiformis (Stossich, 1896), P. fusca (Rudolphi, 1819), P. globiceps (Rudolphi, 1819), P. lateolabracis (Yamaguti, 1935), P. saltatrix Ramachandran, 1973, P. scomberesocis Nikolaeva et Naidenova, 1964, P. serranellicabrillae Janiszewska, 1949and P. tauridica Ivashkin, Kovaleva et Khromova, 1971(see, e.g., Rudolphi 1819Stossich 1896;Janiszewska 1949;Nikolaeva and Naidenova 1964;Orecchia and Paggi 1978;Radujkoviae 1986, 1989;Moravec et al 2003;Moravec and Genc 2004). Most of them are little known and four of them are known by their females only.…”

Gravid or subgravid females of the following three species belonging to the nematode genus Philometra were collected from marine perciform fishes of the Bonifacio Strait Marine Reserve, Corsica, France: Philometra justinei sp. nov. (prevalence 1.5%, intensity 11) and Philometra sp. (prevalence 3%, intensity 2) from the abdominal cavity and gonads, respectively, of the striped red mullet Mullus surmuletus (Mullidae), and Philometra serranellicabrillae Janiszewska, 1949 (prevalence 27%, intensity 2-6) from the gonads of the comber Serranus cabrilla (Serranidae). The newly described species, P. justinei, is mainly characterized by the absence of an anterior bulbous inflation of the oesophagus, body length of the gravid female (196 mm), conspicuously large amphids, number and distribution of cephalic papillae, and the morphology of larvae. It is the second known species of Philometra parasitizing fishes of the family Mullidae and the ninth species of this genus reported from marine fishes of the Mediterranean region. P. serranellicabrillae, studied for the first time by SEM, is redescribed.
