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

Genetic diversity within Cryptosporidium parvum and related Cryptosporidium species. [PDF]

, 1999
To assess the genetic diversity in Cryptosporidium parvum, we have sequenced the small subunit (SSU) rRNA gene of seven Cryptosporidium spp., various isolates of C.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie International Edition, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

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.

The 100 Faces of Cryptosporidium parvum [PDF]

, 2012
Cryptosporidium parvum is a protozoan enteric parasite of humans and livestock. C. parvum infection mainly affects the ileum, where it has the potential to cause severe enteric disease. Drugs for the treatment of cryptosporidiosis are still not available

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.
