Which of the following statements is correct about Cryptosporidium spp.?


The oocyst is always released in the mature and infectious form in this species.
This microorganism represents great importance in public health, since the infectious oocysts are highly resistant to environmental factors, including chlorine, widely used in drinking water treatment.
The non-sporulated oocyst is the infectious form and can be ingested through drinking water and food such as vegetables.
Infection in the blood is the most common and serious illness caused by Cryptosporidium parvum, capable of causing death in a few days.
Cryptosporidium parvum is a bacterium that causes cryptosporidiosis, a common intestinal infection that usually occurs in chronic form in immunocompromised patients.
