Exploring the evolutionary potential of parasites: Larval stages of pathogen digenic trematodes in their thiarid snail host Tarebia granifera in Thailand
This analysis combines the parasites’ data on morphology and geographical occurrence with molecular phylogeny, aiming to provide the groundwork for future studies looking into more details of the parasite-snail evolutionary relationships.
Experimental life cycle of Philophthalmus gralli (Trematoda: Philophthalmidae) in Venezuela.
The intermediate host, Melanoides tuberculata, was collected from freshwater rivulets in Aguasanta and Yaguracual, Sucre State, Venezuela, a new geographical record for P. gralli.
Melanoides tuberculata as intermediate host of Philophthalmus gralli in Brazil.
Melanoides tuberculata that naturally harbored trematode larvae were collected at the Pampulha dam, Belo Horizonte (Minas Gerais, Brazil), during malacological surveys conducted from 2006 to 2010 and adults recovered from the nictitating membranes of chickens were identified as Philophthalmus gralli.
Digenetic Trematodes of Larus genei (Lariformes:Laridae) Caught from Al-Rames Coast of Al-Qateef in Eastern Province of Saudi Arabia
The high species richness, low abundance and diversity of the helminths as compared to those of other gulls reported from other parts of the world reflect the specialized non selective diet of slender-billed gull.
Recovery of Oswaldotrema nacinovici from Whimbrels (Aves) in Korea
Adult specimens of Oswaldotrema nacinovici have been first identified in Korea from 2 migratory birds which were found dead at a western seashore area near Gunsan and it was noteworthy that metacercariae-like bodies were contained within the inflated regions of 2 ceca.
Philophthalmus aweerensis n. sp. (Trematoda: Philophthalmidae) found in a rhea (Rhea americana) in the United Arab Emirates
A new eye fluke species, discovered in the conjunctival cavities of a rhea in the UAE, lacks spination and is characterized by a long cirrus pouch extending behind the caudal margin of the acetabulum, long vitellaria of tubular type reaching the midbody.
Effects of salinity on multiplication and transmission of an intertidal trematode parasite
The strong effect of salinity on the replication and transmission of this parasite suggests that there may be sources and sinks of transmission to birds along coastal areas, depending on local salinity conditions.
Infecção natural de Melanoides tuberculata (Mollusca: Thiaridae) por Centrocestus formosanus (trematoda: Heterophyidae) e por Philophthalmus gralli (Trematoda: Philophthalmidae) no Brasil
Visando avaliar aspectos biologicos e taxonomicos de trematodeos transmitidos por Melanoides tuberculata (Muller, 1774) no Brasil, coletas malacologicas foram realizadas na represa da Pampulha, Belo


Studies on the Biology of Philophthalmus gralli Mathis and Leger, 1910 (Trematoda: Digenea)'
The adult of Philophthalmus gralli occurs in the orbit of wild birds and has been obtained experimentally in chicks. Rodents were refractory to infection by the oral route. Goniobasis spp. and
Occurrence of Philophthalmus gralli Mathis and Leger, 1910 (Trematoda : Philophthalmidae) in a desert spring of the United Arab Emirates
It was found that this fluke at Al-Faydah spring near Al-Ain City utilizes the brackish water snail, Melanoides tuberculatus, as an intermediate host and the water goose, Anser anser, as a definitive natural host.
A comparison of Texan and Hawaiian strains of the avian eyefluke, philophthalmus gralli, with a cautionary note on the importation of exotic animals.
Strains of P. gralli originally from Texas and Hawaii were compared for differences in morphology, growth patterns, mating compatibility, and isozyme mobilities and adult stages of the 2 strains were indistinguishable based on sucker ratios, vitellaria, and egg sizes.

The in vivo growth pattern of Philophthalmus sp., an ocular trematode, was determined by median slit or intraocular inoculations of one to ten larvae into 65 chicks. None to three flukes per eye were
Host-parasite relationships of Zygocotyle lunata (Trematoda) in the domestic chick.
Stunting due to worm crowding was very evident and by 2 weeks post-infection, worms from single-worm infections were sexually mature and more than twice the length of immature flukes obtained from chicks infected with 100-500 cysts.

Worms in all groups produced eggs in which miracidia developed at the same rate and Worms recovered from groups of zero to 10 were significantly longer than those in groups of 41 to 50 and 51 to 60 at all ages sampled.
Life cycle and developmental stages of Philophthalmus gralli in the intermediate and final hosts.
An account of all the developmental stages of the parasite in the molluscan host as well as some information on the early migration of the parasites in the final host are given.
Destruction and regrowth of testes in Philophthalmus gralli, an eyefluke of birds
When pairs of Schistosoma mansoni grown in vitro for long periods of time and with impaired reproductive systems were transplanted to mice, they regained the ability to produce normal eggs and indicated that the male and female could regenerate reproductive tissues or recover from a damaged condition.
Degenerative changes in the reproductive organs of female schistosomes during maintenance in vitro.
The regressive changes in reproductive potential of female S. mansoni maintained in vitro for 4 days could be reversed by surgically implanting the parasites into mouse mesenteric veins.
Effects of stressful conditions on the development and movement of reproductive cells in Schistosoma japonicum.
Adult S. japonicum exposed to 3H-thymidine to label reproductive cells were cultured in vitro, maintained intraperitoneally, or transplanted as unisexual infections to hamsters, where most adults transplanted to the peritoneal cavity of hamsters were dead by day 3, but some lived for 6 days.
