Technical field
[0001] The invention belongs to the detection field of Cryptococcus neoformans, in particular to a staining solution and method for rapidly detecting Cryptococcus neoformans. Background technique
[0002] The diagnosis of Cryptococcus neoformans currently mainly relies on ink smears and fungal culture, and the diagnosis is based on the detection of pathogens. In terms of rapid diagnosis, although direct smear ink staining is simple, it is relatively difficult to observe under the microscope, so the positive detection rate is low. Foreign literature reports that the positive rate is only 53%~56% even in the case of multiple inspections. There are certain false positives and it is difficult to count cryptococcus. Traditional fungal culture usually takes several days. Although the positive rate of culture can reach more than 90%, the diagnosis is delayed due to the long cycle. Animal inoculation can detect some patients with high clinical suspicion and negative sme...
