Ultrasonic treatment of Cryptosporidium oocysts

open access: yesWater 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 ...

Congenital Transmission of Toxoplasma gondii After Experimental Reinfection With Brazilian Typical Strains in Chronically Infected Sheep

open access: yesFrontiers in Veterinary Science, 2019
Toxoplasma gondii is a cause of congenital diseases, miscarriages and stillbirths in production animals. In Brazil, non-archetypal genotypes of the parasite may be related to severe disease. Experimental infection with T.

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Transgenic selection and underlying mechanisms in apicomplexan parasites

open access: yesThe FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Evaluation of sulfadimidine, amprolium and triquen to treat coccidiosis in wild pigeons

open access: yesBrazilian Journal of Biology, 2021
Coccidiosis remains one of the major problems in poultry all over the world. Very limited data on anticoccidial drugs in wild pigeons is available. The current study was aimed to understand the comparative efficacy of sulfadimidine, amprolium and triquen

Infection of Cryptoshoridium parvum Oocysts to Cultured Cells and Detection of the Oocysts by ELISA.

open access: yesJournal of Japan Society on Water Environment, 2000
For developing water treatment system to prevent waterborne Cryptosporidiosis, it is necessary to estimate the inactivation of Cryptosporidium. Recently, cell culture model has developed into a tool that can be used for assessing the viability and/or infectivity of Cryptosporidium oocysts.

Shedding of oocysts by immunocompetent individuals with cryptosporidiosis [PDF]

open access: yesJournal of Hygiene, 1985
SUMMARYStudies were made on 33 immunocompetent patients with cryptosporidiosis (31 of them children) to determine how long oocyst shedding continued after the cessation of diarrhoea. The majority (20/33) ceased to shed oocysts in the week following the cessation of diarrhoea. However 5 patients (15%) continued to shed oocysts for 2 weeks or more, and 1
