Application of fluorescence microscope in detection of parasites in water
release time:2020-07-03

People often say that water is the source of life, so the quality of drinking water is directly related to human health. In addition, Giardia and Cryptosporidium are the two main water borne protozoan parasites that lead to human diarrhea, which are the important factors that can not be ignored in recent years In the field of water quality monitoring, more and more attention has been paid to the detection of two insects. Next, let's take a look at the two insects under the fluorescence microscope.

 "Two worms" mainly infect humans through contaminated drinking water or food. Their oocysts or cysts are small, low pathogenic dose, strong resistance to environmental pressure, simple infection mode, easy to outbreak and epidemic, and have a global distribution, seriously endangering water quality. Human beings are generally susceptible to "two worms" disease. Most of the infected people have clinical symptoms such as acute, chronic diarrhea, low fever and even death. Most of the antibiotics have no effect on it. The resistance to infection mainly depends on the human body's own immunity.

Water borne infection is the main source of "two worm" diseases, and the cost of treatment after infection is much higher than that of prevention in advance, which has become a public health disease to be prevented and controlled in various countries. In 2006, the hygienic standard for drinking water in China added the test of "two insects" in microbiological indicators, which shows the importance of monitoring the "two insects" in drinking water. "Two insects" seriously threaten people's drinking water, and water quality monitoring units are facing a strict test.

Immunomagnetic separation and immunofluorescence are the main methods for the detection of "two insects" in water. The operation process of immunomagnetic separation is complicated, manual operation is required, and the operator needs to be very careful. The instrument is expensive to use, difficult to maintain, and difficult to detect, which limits the practicability and popularity of the detection method to a certain extent. Immunofluorescence method uses professional fluorescence microscope to distinguish impurities and two insects. Guangzhou mingmeiguang provides a professional "two insects" detection scheme. It uses research-level led fluorescence microscope to detect "two insects" in drinking water. The imaging fluorescence signal is strong, the instrument is simple to operate, and the detection rate is high. The product performance and effect are comparable to similar imported products. The high cost performance and good service concept are highly recognized by customers in the industry.
