Cryptosporidiosis is caused by protozoan parasites belonging to the genus Cryptosporidium. These microscopic parasites can infect the intestinal tract of humans and animals, leading to gastrointestinal illness. The main symptoms typically include diarrhea, stomach cramps, and nausea. Recognizing that Cryptosporidium is a protozoan helps in understanding the nature of the disease and the methods of prevention and treatment.

The other types of infections listed, such as viral, bacterial, and fungal, are caused by different categories of pathogens. Viral infections are caused by viruses, which are much smaller than bacteria and can replicate only inside host cells. Bacterial infections are the result of pathogenic bacteria, which can grow independently and produce toxins that lead to illness. Fungal infections come from fungi, which can range from yeasts to molds and typically thrive in warm, moist environments. Understanding the specific pathogens involved in various infections is critical for effective management and control in food safety practices.
