“…of N. girellae on the eyes indicated in parenthesis **: excluding fins shaped pads; male and female genital apertures opened near the left side of body. Further, the parasite was included in the genus Neobenedenia, on the grounds that it lacked vagina and that the accessory gland reservoir (= prostatic reservoir) was contained in the penis sac (Whittington and Horton, 1996). Finally it was identified as Neobenedenia girellae, as the above measurements were in well accordance with those of this species described from fishes of Japan .…”

“…Similarly, in tilapia, Oreochromis mossambicus, infected with N. melleni (=N. girellae; Whittington and Horton, 1996), parasites were found attached to the skin of the anteriodorsal portion of the head and the eyes (Kaneko II et al, 1988). Probably, the same mechanisms will have accounted for the apparently biased distribution in the present case too.…”

ABSTRACT-A benedeniid parasite infecting the body surface of cobia Rachycentron canadum cultured in net cages in Taiwan was identified as Neobenedenia girellae. This is the first confirmed case of N. girellae infection of marine fish from Taiwan. N. girellae was not randomly distributed on the host; it concentrated on the dorsal side of the head area (59.7%), especially on the eyes (23.7%), while it was less frequent on the ventral side and not detected on the fins. N. girellae caused considerable histological damage to the host through the attachment by the haptor and possibly through feeding activity by the pharynx. In infected eyes, epithelial cells of the cornea were often partially lost, and the collagenous stroma was considerably thickened and edematous, associated with massive inflammatory cell infiltration.

“…Concurrent studies by Timofeeva (1990) and Whittington (e.g. Horton & Whittington, 1994 ;Whittington & Horton, 1996 ;Whittington et al 2001 b) have made comprehensive morphological evaluations of particular genera (Dioncus ; Metabenedeniella; Neobenedenia ; Benedenia and Menziesia) and as a result, several genera and subfamilies are now better defined. In particular, Timofeeva (1990) included dioncids in the Capsalidae as the Dioncinae, based on haptoral characteristics and morphology of reproductive structures.…”

“…Neobenedenia melleni is a particularly notorious, widespread pathogen of teleosts in aquaria and aquaculture and is aberrant among Monogenea because of its broad host-specificity (>100 host teleost species; Whittington & Horton, 1996 ;Deveney et al 2001). Extensive morphological variation for N. melleni from different host species is reported and attributed to host induced morphological variation (Whittington & Horton, 1996). Our study incorporated 2 ' N. melleni ' ' isolates ' (identified morphologically) from different host species and localities (ex Oreochromis sp.…”

A preliminary phylogenetic analysis of the Capsalidae (Platyhelminthes: Monogenea: Monopisthocotylea) inferred from large subunit rDNA sequences

et al. 2004

Phylogenetic relationships within the Capsalidae (Monogenea) were examined using large subunit ribosomal DNA sequences from 17 capsalid species (representing 7 genera, 5 subfamilies), 2 outgroup taxa (Monocotylidae) plus Udonella caligorum (Udonellidae). Trees were constructed using maximum likelihood, minimum evolution and maximum parsimony algorithms. An initial tree, generated from sequences 315 bases long, suggests that Capsalinae, Encotyllabinae, Entobdellinae and Trochopodinae are monophyletic, but that Benedeniinae is paraphyletic. Analyses indicate that Neobenedenia, currently in the Benedeniinae, should perhaps be placed in a separate subfamily. An additional analysis was made which omitted 3 capsalid taxa (for which only short sequences were available) and all outgroup taxa because of alignment difficulties. Sequence length increased to 693 bases and good branch support was achieved. The Benedeniinae was again paraphyletic. Higher-level classification of the Capsalidae, evolution of the Entobdellinae and issues of species identity in Neobenedenia are discussed.

“…Of particular concern to the Japanese Seriola industry are 4 monogenean parasite species : Heteraxine heterocerca and Zeuxapta seriolae (Polyopisthocotylea: Heteraxinidae) which infect the gills of their hosts and Benedenia seriolae and Neobenedenia girellae (Monopisthocotylea : Capsalidae) which infect the skin of their hosts. There is a difference of opinion between Ogawa et al (1995) and Whittington and Horton (1996) about whether N. girellae is a valid species. Due to their direct life cycles, monogeneans can proliferate quickly in culture systems if they are not managed appropriately.…”

Egg-laying patterns and in vivo egg production in the monogenean parasites Heteraxine heterocerca and Benedenia seriolae from Japanese yellowtail Seriola quinqueradiata

SUMMARYEgg-laying patterns and egg production in Heteraxine heterocerca from the gills and Benedenia seriolae from the skin of Japanese yellowtail Seriola quinqueradiata in Japan were investigated in vivo. Eggs were collected every 3 h from sexually mature H. heterocerca and B. seriolae infecting 3 S. quinqueradiata kept individually over 3 consecutive days and exposed to alternating periods of illumination and darkness (LD 12:12; light on 06.00, light off 18.00) and maintained at 23·8±0·1°C and 35 ppt salinity. A well-defined egg-laying rhythm was demonstrated for H. heterocerca while B. seriolae was shown to release eggs continuously. A total of 114 000 H. heterocerca eggs was collected and of these, 45·4 (42·5–49·9)% were collected during the first 3 h period following dark at 18.00 h. A total of 662 857 B. seriolae eggs was collected and these were distributed over each 3 h period ranging from 11·1 to 14·1% of the daily egg output. All eggs extracted from the uterus of each H. heterocerca were joined together forming an ‘egg-string’. The contrasting egg-laying patterns of H. heterocerca and B. seriolae suggest that each species makes use of a different infection strategy to infect the same host species, S. quinqueradiata.
