Ultrasonic treatment of Cryptosporidium oocysts

Water Science and Technology, 2003
The effect of 20 kHz ultrasound on the viability of Cryptosporidium oocysts was investigated. More than 90% of the dispersed Cryptosporidium oocysts could be deactivated in about 1.5 min of continuous sonication. In order to apply this technique to large quantities of contaminated water, quantitative filtration and redispersion of Cryptosporidium ...

Nanoparticle Lysis of Cryptosporidium Oocysts

Methods and Protocols
The extraction of DNA from Cryptosporidium oocysts is challenging due to the robust oocyst wall. Nanoparticles have been applied to disinfect Cryptosporidium oocysts; here, we demonstrate the utilisation of nanoparticles to disrupt the oocyst wall to enable sporozoite lysis and detection via PCR.

Effectiveness of Ginsenoside Rh2 Treatment in Mice Experimentally Infected With Cryptosporidium parvum. [PDF]

Vet Med Sci
• This study evaluated the therapeutic effects of Ginsenoside Rh2 in mice experimentally infected with Cryptosporidium parvum and compared two dosing regimens. • Ginsenoside Rh2 reduced faecal oocyst shedding and improved body‐weight recovery in C. parvum‐infected mice.

Therapeutic Effects of Matricaria chamomilla Extract in an Immunosuppressed Mouse Model of Cryptosporidiosis. [PDF]

Vet Med Sci
Chamomile (Matricaria chamomilla) extract significantly reduced oocyst shedding and intestinal lesions in immunosuppressed mice infected with Cryptosporidium parvum, while enhancing antioxidant defences (GPx, TAC). These findings suggest chamomile as a promising phytotherapeutic agent for cryptosporidiosis. ABSTRACT Background Cryptosporidiosis, caused

Late Embryogenesis Abundant Proteins Contribute to the Resistance of Toxoplasma gondii Oocysts against Environmental Stresses [PDF]

, 2023
Toxoplasma gondii oocysts, which are shed in large quantities in the feces from infected felines, are very stable in the environment, resistant to most inactivation procedures, and highly infectious. The oocyst wall provides an important physical barrier

Genotypes of Cryptosporidium Species Infecting Fur-Bearing Mammals Differ from Those of Species Infecting Humans [PDF]

, 2004
Of 471 specimens examined from foxes, raccoons, muskrats, otters, and beavers living in wetlands adjacent to the Chesapeake Bay, 36 were positive for five types of Cryptosporidium, including the C.

PRACTICAL EXPERIENCE IN USING THE MINI PARASEP FAECAL PARASITE CONCENTRATOR FOR CRYPTOSPORIDIUM SPP. OOCYSTS DETECTION IN STOOL [PDF]

Annals of Mechnikov's Institute, 2018
Introduction. Cryptosporidiosis is a protozoan illness caused by the protozoans of genus Cryptosporidium (type Apicomplexa), that are able to parasitize in the enterocytes of the intestinal mucosa villi, causing a specific infectious process with such ...

Administering Eimeria maxima oocysts through drinking water improves coccidiosis vaccine uptake in broiler chickens

Journal of Applied Poultry Research, 2023
SUMMARY: Vaccination against avian coccidiosis is increasingly being used by the poultry industry to prevent outbreaks of this parasitic disease, but problems with nonuniform administration of Eimeria oocysts by spray vaccination at the hatchery is ...
