REDESCRIPTION AND SURFACE ULTRASTRUCTURE OF PYGIDIOPSIS MACROSTOMUM (DIGENEA: HETEROPHYIDAE)

Journal of Parasitology, 2005
Pygidiopsis macrostomum Travassos, 1928, a poorly known species originally described from a single specimen from Rattus norvegicus (Erxleben, 1777) in Brazil, is redescribed on the basis of metacercariae from the mesenteries of naturally infected guppies Poecilia vivipara Bloch and Schneider, 1801 (Poeciliidae), and adults obtained from an experimental

Surface Ultrastructure of the Developmental Stages of Heterophyopsis continua (Trematoda: Heterophyidae)

The Journal of Parasitology, 1991
Ultrastructural observations were made on the tegument of juvenile and adult stages of Heterophyopsis continua using scanning electron microscopy. On the surface posterior to the ventral sucker, the tegumental processes were bandlike in the metacercariae, cobblestonelike in the flukes 2 days postinfection (PI), and velvety at 3 days PI.

ELISA and some biochemical tests of heterophyidae infection in laboratory animals

Parasitology Research, 2011
Heterophyiasis is an important food-borne parasitic zoonosis in Egypt, among the inhabitants living around brackish-water lakes especially fishermen, and it is a common human parasite in the Nile Delta. The experiment was done on two laboratory animals (rats and dogs), and the time of sample collection was done periodically at 6, 9, 15, 21, and 28 days

Observations on Some Heterophyidae (Trematoda: Digenea) Encysted in Philippine Fishes

The Journal of Parasitology, 1973
The following species of Heterophyidae are redescribed from adults obtained from experi- mental definitive hosts fed metacercariae from Philippine fishes: Heterophyopsis expectans (Africa and Garcia, 1935) Tubangui and Africa, 1938 (neotype) and Procerovum calderoni (Africa and Garcia, 1935) Price, 1940 (neotype); Haplorchis pumilio (Looss, 1896) Looss,

HaplorchoidesChen, 1949 (Haplorchinae: Heterophyidae) in freshwater fishes

Journal of Helminthology, 1976
AbstractTwo metacercariae ofHaplorchoides, recorded in the fingerlings of over a dozen species of freshwater fishes, are described and illustrated. Oyigerous flukes were recovered from older specimens of two species of fishes procured from the same locality.

Stictodora lari (Digenea: Heterophyidae): The Discovery of the First Human Infections

The Journal of Parasitology, 2002
Stictodora lari Yamaguti, 1939 (Digenea: Heterophyidae) was originally reported as an avian intestinal parasite and is here reported in humans. The patients were adults, aged 46-69 (2 men and 4 women), who resided in coastal villages in Sachon-gun, Kyongsangnam-do, or Shinan-gun, Chollanam-do. in the Republic of Korea.

In vitro excystation of Haplorchis taichui (Trematoda: Heterophyidae).

The Southeast Asian journal of tropical medicine and public health, 2002
The effects of trypsin, bile extract, temperature and acid-based condition for the in vitro excystation of Haplorchis taichui metacercariae were studied. At 37 degrees C, approximately half the number of metacercariae excysted when exposed to 1% trypsin for 15 minutes with no more excystation found beyond this time.

Optimization of an Experimental Model for the Recovery of Adult Haplorchis pumilio (Heterophyidae: Digenea)

Journal of Parasitology, 2009
Recent studies in Vietnam and other Asian countries have shown that fish-borne zoonotic intestinal trematodes (FZT) occur very frequently in humans. The dominant intestinal FZT in Vietnamese fish are species of Haplorchis, in particular H. pumilio. However, basic studies on the biology and pathology of adult H. pumilio are difficult because of the lack

The Life Cycle of Pygidiopsis ardeae Koie, 1990 (Digenea, Heterophyidae)

The Journal of Parasitology, 1990
Ocellate cercariae, consistent with the description of Cercaria angularis Honer, 1961, developing in rediae in Hydrobia ulvae (Pennant) and Hydrobia ventrosa (Montagu) (Prosobranchia, Hydrobiidae) from Denmark, were shown to be larvae of Pygidiopsis ardeae Køie, 1990 (Heterophyidae, Pygidiopsinae).
