Detection of Cryptosporidium parvum oocysts in calf fecal samples by direct immunofluorescence assay Detecção de oocistos de Cryptosporidium parvum em amostras fecais de bezerros pela reação de imunofluorescência direta

Revista Brasileira de Parasitologia Veterinária, 2011
The aim of this study was to produce a conjugate containing anti-Cryptosporidium parvum polyclonal antibodies and standardize a Direct Immunofluorescence Assay (DIF) for detecting C. parvum oocysts in fecal samples from calves. In order to obtain anti-C.

Identification of Cryptosporidium parvum IIa and IId zoonotic subtype families and Cryptosporidium bovis from calves in Algeria

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2023
Cryptosporidiosis is a significant disease in calves caused by the parasitic protist Cryptosporidium. The infection results in severe symptoms such as diarrhea, dehydration, delayed growth, and weight loss, often leading to mortality and economic losses.

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

Cryptosporidium Priming Is More Effective than Vaccine for Protection against Cryptosporidiosis in a Murine Protein Malnutrition Model. [PDF]

PLoS Neglected Tropical Diseases, 2016
Cryptosporidium is a major cause of severe diarrhea, especially in malnourished children. Using a murine model of C. parvum oocyst challenge that recapitulates clinical features of severe cryptosporidiosis during malnutrition, we interrogated the effect ...

Modeling Factors Associated With Diarrhea Caused by Cryptosporidium Species Using Machine Learning Methods

Journal of Clinical Laboratory Analysis, EarlyView.
This study applies machine learning methods, specifically Random Forest and Bagged CART, to classify Cryptosporidium spp. infections among children and identify key risk factors. The Bagged CART model demonstrated superior sensitivity and predictive performance, highlighting household crowding and water source as the most influential determinants of ...

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 ...

Impacts of rodents in piggeries in Australia – review and pilot impact study

Pest Management Science, EarlyView.
Rodent impacts in Australian piggeries are under‐researched, with limited data on economic losses and control costs. A review and pilot study found average losses of AUD$100 000 annually. Key concerns include disease, damage, and control expenses.
