Comparison of tissue culture and animal models for assessment of Cryptospridium parvum infection.

The current increased interest for using tissue culture as a surrogate for mouse infection to assess Cryptospridium viability suggests that a comparison of the two models is essential for data interpretation. Therefore, a need remains for a statistical comparison that can demonstrate if infection and inactivation predicted by new tissue culture models are comparable with those predicted by animal models. Data from a total of 31 dose-response trials using both tissue culture and mouse models to assess C.

Low- and medium-pressure UV inactivation of microsporidia Encephalitozoon intestinalis.

Newly recognized waterborne pathogens such as microsporidia are being detected in the world's water supplies with increasing frequency. Many of these organisms have been shown to cause negative health impacts for both immunocompetent as well as immunocompromised individuals. It is imperative that these emerging pathogens be investigated for their ability to resist both traditional and novel disinfection technologies that are currently in use or under consideration for drinking water treatment.
