Early Induction of Human Regulatory Dermal Antigen Presenting Cells by Skin-Penetrating Schistosoma Mansoni Cercariae [PDF]

Frontiers in Immunology, 2018
Following initial invasion of Schistosoma mansoni cercariae, schistosomula reside in the skin for several days during which they can interact with the dermal immune system. While murine experiments have indicated that exposure to radiation-attenuated (RA)

Competent Non-Native Alternative Host Reduces Infection Success in a Generalist Parasite. [PDF]

Ecol Evol
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

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 ...

Salt in the Wound: Assessing Pathogen Susceptibility in Amphibian Populations Across a Gradient of Salt Pollution. [PDF]

Ecol Evol
The survival function of nine larval wood frog populations and their viral loads when exposed to FV3. The populations were collected as eggs from a range of salt‐polluted ponds. Viral load data are means ±1 SE. The populations are ordered in terms of the saltiness of their natal ponds.

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.

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.

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.
