Serum IgG Responses to gp15 and gp40 Protein-Derived Synthetic Peptides From Cryptosporidium parvum

Frontiers in Cellular and Infection Microbiology, 2022
Cryptosporidium spp. are responsible for moderate to severe diarrhea, mainly in children and immunocompromised patients. Using ELISA, the recognition of synthetic peptides generated from the sequences of the Cryptosporidium parvum gp40 and gp15 proteins ...

In Vitro Antiparasitic Effects of Silver Nanoparticles on Sarcocystis Bradyzoites

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
In vitro, silver nanoparticles (AgNPs) exhibit dose and time‐dependent antiparasitic activity against Sarcocystis bradyzoites from sheep, achieving up to 59.53% mortality at 800 µg/mL after 120 min. These results suggest AgNPs may be a potential alternative to traditional drugs, meriting further in vivo investigation for veterinary use.

Risk Ranking of Microbiological Hazards in Food (2015–2019)

Food Risk Assess Europe, Volume 4, Issue 3, July 2026.
Abstract Microbiological food safety risks arise from pathogens that can contaminate food at different points along the food chain. Exposure to these hazards can result in illnesses that can vary widely in severity and duration, depending on factors such as the specific pathogen involved, the amount of the pathogen ingested, and the susceptibility of ...

High diversity of Cryptosporidium subgenotypes identified in Malaysian HIV/AIDS individuals targeting gp60 gene. [PDF]

PLoS ONE, 2012
BACKGROUND: Currently, there is a lack of vital information in the genetic makeup of Cryptosporidium especially in developing countries. The present study aimed at determining the genotypes and subgenotypes of Cryptosporidium in hospitalized Malaysian ...

Freshwater Mussel Anodonta cygnea Reduces Concentration, Germination Rate and Infectivity of Pathogenic Oomycete Saprolegnia spp. Spores

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Saprolegniosis, also known as water mould, is a lethal disease caused by Saprolegnia oomycetes that threatens freshwater animals including fish, amphibians, and crustaceans, as well as aquaculture. It causes biodiversity loss and population declines, including those of endangered fishes.

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 ...

Characterization of the Cryptosporidium antigens from sporulated oocysts of Cryptosporidium parvum [PDF]

Infection and Immunity, 1987
The antigenic constituents of sporulated Cryptosporidium parvum oocyst antigens were characterized with antisera from mice immunized against C. parvum. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis followed by silver staining defined the major proteins. Six of seven lectins used recognized as many as 15 bands.

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 ...

Comparative analysis reveals conservation in genome organization among intestinal Cryptosporidium species and sequence divergence in potential secreted pathogenesis determinants among major human-infecting species

BMC Genomics, 2019
Background Cryptosporidiosis is a major cause of gastrointestinal diseases in humans and other vertebrates. Previous analyses of invasion-related proteins revealed that Cryptosporidium parvum, Cryptosporidium hominis, and Cryptosporidium ubiquitum mainly
