Antigen incorporation on Cryptosporidium parvum oocyst walls [PDF]

Memórias do Instituto Oswaldo Cruz, 2001
Cryptosporidium parvum oocysts are the infective stages responsible for transmission and survival of the organism in the environment. In the present work we show that the oocyst wall, far from being a static structure, is able to incorporate antigens by a mechanism involving vesicle fusion with the wall, and the incorporation of the antigen to the ...

Zoonotic Transmission Assessment of Cryptosporidium spp. in Close Human–Pet Environments in Yunnan Province, China

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study revealed Cryptosporidium infection rates of 11.1% in dogs and 10.4% in cats in human–pet environments in Yunnan, China. Molecular evidence documents one case of pet‐to‐human transmission involving an immunocompromised elderly owner, suggesting vulnerable individuals face higher infection risks despite minimal transmission to immunocompetent ...

Genetic Diversity of Cryptosporidium parvum in Neonatal Dairy Calves in Xinjiang, China

Pathogens, 2020
Cryptosporidium parvum has been identified as a major cause of diarrhea and diarrhea-associated deaths in young children and neonatal calves. Infections can remain asymptomatic but may lead to malnutrition and persistent growth retardation. To assess the

Looking for Greener Pastures: In Vitro Screening of Phytogenics for the Control of Sparicotyle chrysophrii in Gilthead Sea Bream

Journal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT The gill parasite Sparicotyle chrysophrii poses a significant threat to gilthead sea bream (Sparus aurata) aquaculture in the Mediterranean, causing considerable mortality and economic losses. As traditional chemotherapeutic treatments, like formalin, face growing regulatory restrictions, there is an urgent need for alternative control ...

Cryptosporidium Parvum Infection among Egyptian School Children [PDF]

Journal of the Egyptian Society of Parasitology, 2015
The present study determined cryptosporidiosis among 120 randomly chosen school children aged 4-16 years. Medical sheets were filled out on each child. The fresh stool samples were examined by using Sheather's sugar flotation stained with modified Ziehl Neelsen stain. Blood samples were examined by ELISA and IFA techniques.

Murine Intestinal Neonatal and Adult Dendritic Cell Subset Migration and Activation Characteristics in Response to Toll‐Like Receptor Stimulation Through MyD88

Scandinavian Journal of Immunology, Volume 103, Issue 4, April 2026.
Despite their importance, dendritic cell subsets are not well characterised in neonates. We here provide fundamental information on the abundance and phenotype of small‐intestinal neonatal DCs and assess the role of MyD88 in neonatal and adult DC migration in response to several toll‐like receptor ligands.
