The study by Professor Eva Goldis of UNSW's Graduate School of Biomedical Engineering and her team confirm,
Cryptosporidium is a genus of protozoa, single-celled organisms that cause diseases of the human gastrointestinal tract. Some species of Cryptosporidium are capable of infecting humans, causing the digestive system disease cryptosporidiosis, which is not usually dangerous for people with healthy immune systems, but is often fatal for people who are immunocompromised.
The new technology also has the potential for further development and could identify other types of viruses, including COVID-19, in wastewater samples.
Until now, for the detection of cryptosporidium more oftenall required the use of expensive laboratory equipment, specialized microscopes, and skilled training to identify a microbe in a water sample. But the new method, which the researchers have developed, is cheaper, easier to use, and requires little or no special training to analyze the results. The system creates a characteristic fluorescent light in the water sample when it detects cryptosporidium.
The authors note that the new development identifies even one sample of the virus in a sample, provided that even two microbes cancause a serious infection.
