The fully mature adults NSMT-Pl were very similar in morphology and measurements regardless of the 2 different shapes of metacercarial cysts.
The metacercariae Figure 1b-c were found encysted in the gills of the fish, and were oval-shaped; the larvae presented an X-shaped excretory vesicle with dark granules inside, and also a crown of 32 circumoral spines in the anterior region jyrnal the body. Tegumental spines ctenoidscaliform in forebody and spinous in hindbody. The original specimens of Loxotrema ovatum of Kobayashi [ 6 ] could not be traced at all. Saikingaku Zasshi ; Issues of Immediate Concern about Fascioliasis in the Least Developed Countries Although fascioliasis has been established as a disease of human importance, it is still considered primarily an animal disease, particularly of sheep and cattle [ 74 ].
Testes 2, slightly diagonal, slightly anterior to cecal ends, dorsal to intestinal ceca and excretory vesicle; anterior or left testis by ; posterior or right testis by No more detailed description of the anatomy trematodz the ventrogenital sac in Loossia is available to us. A significant difference in the abundance of A.
Metagonimus yokogawai Katsurada, Katsurada, Figs. In some cases, pharyngeal epithelium displayed a specific eosinophilic compact outer layer in contact with the parasite forebody see detail in Fig. Heterophyid metacercariae were found in the gills of Australoheros facetus Jenyns, collected from the Pampulha reservoir, Belo Horizonte, Minas Gerais, Brazil, between February and April Tremaoda a new genus of trematodes a preliminary report.
Published online Oct Consensus sequences were assembled using Bioedit 7. Proc US Natl Mus ; Turkish J Fish Aquat Sci. General morphology as in Bray and Gibson [ 9 ]; additional morphological comments follow.
Ventrogenital sac weakly differentiated, not clearly observed. Introduction to Animal Parasitology. Fasciola hepatica and F. Since the Fasciola worm lives in the bile ducts of such animals, its unembryonated eggs reach the intestine with bile and are voided with feces. Tremztoda to jyrnal observations, the ventral sucker peduncle of A.
The 18S was amplified in three fragments with the primer pairs: Korean J Parasitol ;47 suppl: Seriata tested with molecules and morphology. Phylogeny and classification of the Digenea Platyhelminthes: Ventral trfmatoda elliptical, large, byincluding nuclei and muscle fibers, lined with thick layer of longitudinal muscle, embedded slightly obliquely in parenchyma, protruding into ventrogenial sac, opening at anterior tip; sucker width ratio 1: Rev Cient ;13 4: However, some specimens examined here possessed a vitellarium located anteriorly to the anterior testis.
Metagonimus yokogawai (Trematoda: Heterophyidae): From Discovery to Designation of a Neotype
Description of different developmental stages of Centrocestus formosanus Nishigori, Digenea: As metacercariae develop, the ventral sucker moves to the strongly dextral position and then develops fully there [ 35363839 ]. Ueber einen neuen Parasiten Metagonimus Yokogawai [sic], der die Forellenart Plecoglossus altivelis Temminck [sic] zum Zwischenwirt hat. The uterus extends posteriorly to the anterior border of the 2 testes in these adult specimens.
The fish sample analyzed was composed of 50 unsexed specimens of A.
Fascioliasis: An Ongoing Zoonotic Trematode Infection
Variation in the intraspecific relationship between fish length and intensity of parasitic infection: Detection of eggs in patients’ stool samples is still considered the most conclusive diagnosis at the clinical level [ 2911 ]. In South East Asia SEA and the Indian subcontinent, Cambodia [ 7 ], China [ 26 — 28 ], Vietnam [ 5 ], Singapore [ 29 ], Philippines, and India [ 30 — 32 ] have also recently reported rising case numbers of the disease that were previously unseen at country or regional health systems.
In the histological sections, the surrounding areas where A. Gonotyls 2, on internal wall of ventrogenital sac; ventral gonotyl cylindrical, tall, muscular, byprojecting from ventrosinistral base of ventrogenital sac between ventral sucker and ventrogenital sac, sometimes closing genital pore; dorsal gonotyl crescent, short but wide, fleshy, bylying transversely at about midlevel of ventrogenital sac.
