Incidence of Centrocestus formosanus Infection in Snails

The Journal of Parasitology, 1987
fluent monolayers of host cells that had been thoroughly rinsed for several hours with serumfree medium. Each monolayer was then covered with a 12-mm-diameter circular coverslip and examined by phase-contrast microscopy. We observed many of the sporozoites undergoing active motility on the surface of both HepG2 and WI38 cells; this was manifested as ...

Development of Centrocestus armatus in different final hosts

Veterinary Parasitology, 2007
In this study, Centrocestus armatus metacercariae were fed orally to hamsters, albino rats, mice, and chicks. Animals were sacrificed and dissected at 1, 3, 5, 7, and 14 days post-infection to determine the development and recovery rate of worms. Results indicated that the average worm recovery rate in hamsters was 25% on the first day post-infection ...

Centrocestus formosanus: surface morphology of metacercaria, adult and egg

Journal of Helminthology, 1997
AbstractThe surface morphology of metacercariae isolated from Puntius spp., adult worms from infected hamsters and eggs of Centrocestus formosanus (Digenea: Heterophyidae) were studied using scanning electron microscopy. It was found that the surfaces of the metacercariae and adult worms were closely similar in appearance.

Surface ultrastructure of juvenile and adult stages of Centrocestus armatus

Journal of Helminthology, 1998
AbstractCentrocestus armatus (Trematoda: Heterophyidae) develops rapidly and produces eggs at 3 days postinfection in albino rats. Excysted metacercariae are pear-shaped and concave ventrally, with 42–44 peg-like circumoral spines. The entire body surface is densely covered with scale-like serrated spines.

Infection Dynamics of Centrocestus armatus Cercariae (Digenea: Heterophyidae) to Second Intermediate Fish Hosts

Journal of Parasitology, 2007
The infection dynamics of Centrocestus armatus cercariae with respect to second intermediate fish hosts were investigated using cercariae collected from naturally infected Semisulcospira libertina. Cercariae survival and infectivity were recorded at 2-hr intervals. Survival remained constant but decreased abruptly at 30 hr of age.

Streptococcus, Centrocestus formosanus and Myxobolus tilapiae concurrent infections in farmed Nile tilapia (Oreochromis niloticus)

Microbial Pathogenesis, 2021
Stress triggered concurrent microbial/parasitic infections are prevalent in earthen pond based farmed Nile tilapia Oreochromis niloticus. In the current study, a total of thirty five O. niloticus were collected from a commercial fish farm with a history of severe mortalities at Port Said, Egypt.

Characterization of the microbial community in the gut of Centrocestus formosanus

South Asian Journal of Experimental Biology, 2013
The antibiotic resistance pattern of bacteria associated with the gut of Centrocestus formosanus, an aggressive wood‐eating termite was investigated. The bacterial isolates encountered were Serratia marcescens, Acetobacter posterianus, Flavobacterium rigense, Xanthomonas spp, Citrobacter freundii, Erwinia cacticida, Aeromonas salmonicida ...

[Sensillae and protonephridia of cercaria of Centrocestus formosanus and Centrocestus sp. (Centrocestinae, Heterophyidae)].

Annales de parasitologie humaine et comparee, 1983
A description is given of cercarial chaetotaxy of two Centrocestinae (Heterophyidae, Opisthorchioidea) from Malaysia: Centrocestus formosanus and Centrocestus sp.--Comparison with cercarial chaetotaxy of taxonomically related groups indicates that 1. The chaetotaxy of the Centrocestinae agrees with that of other Opisthorchioidea, 2.

Human infection of Centrocestus caninus in Thailand.

The Southeast Asian journal of tropical medicine and public health, 1998
Examination of fecal samples, collected after treatment with praziquantel, of the persons positive with opisthorchioid eggs residing in the northern provinces of Thailand, was carried out. Five adults Centrocestus were recovered in one sample from Doi Saket, Chiang Mai and one adult was found in another fecal sample from Wiang Pa Pao, Chiang Rai.

Severe outbreak of Centrocestus formosanus (Trematoda: Heterophyidae) in farm-raised ornamental platies Xiphophorus maculatus

Diseases of Aquatic Organisms, 2019
This report describes a severe outbreak of the gill fluke Centrocestus formosanus in farm-raised platies Xiphophorus maculatus in Brazil, with mortality rate approaching 95%. Typical clinical signs of infection were observed, with microscopic examinations of fresh gills revealing multiple cysts containing a once-folded metacercaria with an X-shaped ...
