Effects of Physicochemical Factors on Loss of Infectivity of Opisthorchis viverrini Cercariae

Walailak Journal of Science and Technology, 2021
This study aims to develop an alternative field-based approach to interrupt the life cycle of O. viverrini. The effects of temperature, salinity, acidity, ultraviolet A, B, C radiation, and combinations of these physicochemical factors on the loss of ...

Ultraviolet disinfection of schistosome cercariae in water [PDF]

, 2022
Schistosomiasis is a tropical disease that is contracted by skin contact with water containing cercariae, larvae of the Schistosoma parasite. Providing safe water for contact activities (e.g. laundry, bathing) can help reduce transmission.

Trematode cercarial fauna obtained from the field-collected freshwater snails Lymnaea natalensis in Egypt

Bulletin of the National Research Centre, 2019
Background Lymnaea natalensis is the snail intermediate host for Fasciola spp. parasites. The purpose of the present investigation is to detect the different trematodes’ larval stages in this snail from three rural localities in Giza Governorate ...

Altered patterns of gene expression underlying the enhanced immunogenicity of radiation-attenuated schistosomes [PDF]

, 2008
Schistosome cercariae only elicit high levels of protective immunity against a challenge infection if they are optimally attenuated by exposure to ionising radiation that truncates their migration in the lungs.

Host-parasite relationships of cercariae of Trichobilharzia stagnicolae.

, 1995
Survival of cercariae of Trichobilharzia stagnicolae from naturally infected Stagnicola emarginata was determined at several different temperatures: 6, 17.5, 22, 27.5, and 32.5 C.

Trematodes obtained from the thiarid freshwater snail Melanoides tuberculata (Müller, 1774) as vector of human infections in Thailand

Zoosystematics and Evolution, 2014
Larval stages of trematodes obtained from the freshwater snail Melanoides tuberculata (Cerithioidea, Thiaridae) as intermediate host were studied by using cercarial emergence and crushing snails.

Effects of Land-Use and Environmental Factors on Snail Distribution and Trematode Infection in Ethiopia

Tropical Medicine and Infectious Disease, 2023
Freshwater snails are intermediate hosts for several snail-borne diseases affecting humans and animals. Understanding the distribution of snail intermediate hosts and their infection status is very important to plan and implement effective disease ...

Fluorescent imaging of antigen released by a skin-invading helminth reveals differential uptake and activation profiles by antigen presenting cells. [PDF]

, 2009
Infection of the mammalian host by the parasitic helminth Schistosoma mansoni is accompanied by the release of excretory/secretory molecules (ES) from cercariae which aid penetration of the skin.

THE DEVASTING EFFECTS OF PRAZIQUANTEL AND ALBENDAZOLE, ON CERCARIAE OFTHEDIGENEANPHANEROPSOLUS PRAOMIDIS (BAER, 1971) [PDF]

Journal of the Egyptian Society of Parasitology
Phaneropsolidae is one of the digenean intestinal parasites of reptiles, birds, and mammals. To cease its life cycle, some cercariacidal drugs were used, such as praziquantel and albendazole. The intermediate host, a freshwater snail, Lanistes carinatus,

The effect of increasing water temperatures on Schistosoma mansoni transmission and Biomphalaria pfeifferi population dynamics: an agent-based modelling study. [PDF]

, 2014
INTRODUCTION: There is increasing interest in the control and elimination of schistosomiasis. Little is known, however, about the likely effects of increasing water-body temperatures on transmission. METHODS: We have developed an agent-based model of the
