Cryptosporidium Parvum Oocysts

The consumption of shellfish has increased considerably worldwide, with an associated increase in foodborne illnesses. Among the bivalves, the mussels are usually cooked by steam, which constitutes a typical dish in several regions. In this article, we demonstrate that this preparation is not sufficient to destroy completely the infectivity of Cryptosporidium parvum. Oocysts recovered from experimentally contaminated mussels (Mytilus galloprovincialis) were infectious to neonatal mice after cooking. Although, to date, no official cases of cryptosporidiosis linked to shellfish consumption have been reported, we recommend that people with reduced immunity avoid this type of food because they are at high risk of being infected with Cryptosporidium spp. after eating raw or undercooked contaminated bivalves.

ABSTRACT Numerous inflammatory cells are recruited in response to Cryptosporidium parvum infection. These cells include interferon gamma-producing T lymphocytes, which are of major importance for the resolution of infection. Here, we show that β7 integrin is not essential for the control of infection in mice but that β7-deficient neonatal mice are more susceptible during the early stages of infection.

Reuse Of Treated Wastewater

ABSTRACT The physicochemical conditions of high-rate algal ponds were responsible for a more than 97% reduction in the infectivity ofCryptosporidium parvum oocysts in neonatal mice. The use of semipermeable bags of cellulose showed that pH, ammonia, and/or light seems to be a major factor for the inactivation of oocysts in wastewater, supporting the importance of alga-based systems for safer reuse of treated wastewater.
