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 ...

Pulsed Electric Fields as an Effective Tool for Toxoplasma gondii Inactivation [PDF]

Foods
Toxoplasma gondii is an intracellular protozoan transmitted via environmentally resistant oocysts present in food and water, as well as through the consumption of meat containing infective bradyzoites. This study evaluated the inactivation of T.

Nanoparticle Lysis of Cryptosporidium Oocysts [PDF]

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.

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

Phylogenetic Analysis of the Most Common Chicken Coccidia, Eimeria acervulina, Isolated From Commercial Poultry Farms in Bangladesh. [PDF]

Vet Med Sci
The ITS‐1 PCR assay detected 96.11% E. acervulina in coccidia‐positive faecal samples from commercial poultry farms. The sequence analysis revealed 15 genotypes and seven single‐nucleotide substitutions, indicating significant genetic diversity. This is the first report of molecular characterization of E. acervulina in Bangladesh.
