title: [The first cholera case diagnosed early in the clinical laboratory by DNA probe method].
abstract: An alkaline-phosphatase-labelled synthetic oligonucleotide probe was applied to detect the structural gene of cholera enterotoxin (ctx). This DNA probe has a complementary base sequence to 30 base of the CT-A subunit. This method was, for the first time, applied to diagnosis of a diarrheal patient. The probe detected ctx rapidly and simply as compared with reversed passive latex agglutination (RPLA) and Beads-ELISA. The cfu minimal dose for detection with the probe was about 10(6-7)/ml. This method can be easily performed in any clinical laboratory because the procedure is safe, simple and rapid (it can be completed within about 3 hours).
