Introduction
Plagiorchis mutationis (Trematoda: Plagiorchidae) is a bird parasite, mainly parasitising fish-eating birds.
It was first described by L. G. Panova in 1927 (Shigina, 1965). The life cycle of this trematode was studied
and described by N. G. Shigina (1965). In the experimental studies, snails Lymnaea ovata have been used as
the first intermediate host.
Published data on life cycles of trematodes from the genus Plagiorchis Luhe, 1899 (Krasnolobova, 1987)
contain information on synonyms of the species Plagiorchis mutationis Panova, 1927 and Plagiorchis laricola
Skrjabin, 1924. In the life cycle of Plagiorchis laricola, snails from the family Lymnaeidae, in particular
Lymnaea (Ampullaceana) ovata, Lymnaea (Lymnaea) stagnalis, Lymnaea (Peregriana) peregra are the first
intermediate hosts (Êrasnolobova, 1971; 1987).
Material and methods
The work was based on the collections of Lymnaea stagnalis from Grybove Lake in Ovruch district of
Zhytomyr oblast in 2009. More than 300 specimens were examined. Mollusc species was identified by
conchological method with using of anatomical data (Stadnichenko, 2004).
Morphology was studied on active mature cercariae emerging from molluscs, using vital staining with
neutral red and Nile blue sulfate. Cercariae were described based on previously immobilized living specimens.
Results and discussion
During the study of trematodes fauna of mollusks in Grybove lake, cercariae
Xiphidiocercariae of “armatae” group were registered. They belonged to Plagiorchis
mutationis Panova, 1927 as it was revealed during their examination.
Cercariae found in the present study were similar to the larvae of Plagiorchis muta-
tionis registered in Lymnaea (Stagnicola) palustris and described by S. N. Vodyanitskaya
(2006) by their morphological features and size (table 1).

On each side of the body, evenly, one by one, seven fine hairs are visible. Body
length is 0.205 ± 0.010 mm, width 0.112 ± 0.001 mm (fig. 1). Stylet is in the buccal
cavity. Stylet has shoulders, its length is 0.028 ± 0.0002 mm, width is 0.005 ± 0.001 mm
(fig. 2). Buccal sucker is 0.048 • 0.059 mm in diameter, slightly compressed in the lon-
gitudinal direction, similarly to the ventral sucker. Ventral sucker is 0.031 õ 0.038 mm
in diameter; it is smaller than the buccal sucker and is located in the centre of the body.
Nine pairs of penetration glands are on each side of the ventral sucker. The digestive
system is represented by short prepharynx, muscular pharynx 0.026 ± 0.001mm in
length, and 0.019 ± 0.001 mm in width, oesophagus 0.060 ± 0.0002 mm in length, and
intestines. Intestine is bifurcated before the ventral sucker, intestinal branches reach
bladder level.
Excretory system represented by Y-shaped bladder and excretory channels flowing
into it from both sides. Body parenchyma is filled with lipoid droplets. Cercariae has
tail 0.262 ± 0.010 mm in length, 0.030 ± 0.001 mm in width, with no weaverbird.
Until now, cercariae of one trematode species from family Plagiorchiidae: Plagiorchis
elegans (Rudolphi, 1802) have been found in pond mollusks in Ukraine (Stenko, 1983).
At the same time, 11 trematode species from genus Plagiorchis including P. mutationis
were noted in reptiles and birds on the territory of Ukraine (Catalog…, 1995).
Comparative analysis of size and morphology of P. mutationis larvae, their com-
parison with published data of other researchers (Shigina, 1965; Krasnolobova, 1971,
1987; Vodyanitskaya, 2006) showed some differences is measurements and in the num-
ber of penetration glands. According to data of Krasnolobova (1971), in cercaria of
Plagiorchis laricola Skrjabin, 1924 (syn. Plagiorchis mutationis Panova, 1927) 7–8 pairs
of penetration glands were observed; Zhdarskaya (1966) found 6–8 pairs of these cells,
Reimer (1966–1967) — 7 glands on each side (by Krasnolobova, 1987). The contra-
dictory literature data on the number of penetration glans Krasnolobova (1982, 1987)

explained by different way of their staining resulting in different number of stained cells
that leads to different results. Also, there are some distinctions in measurements
(table 1). Variations in these characteristics directly depended on the method of cer-
cariae fixation (Krasnolobova, 1987).
During the study of parasitic fauna of Grybove Lake, we found out that in June —
July 2009 prevalence of L. stagnalis infection with P. mutationis larvae was 3.67 ± 1.09%.
