Fig. 1. gel electrophoresis showing positive polymerase chain reaction (PCR) products from cerebrospinal fluid (CSF) samples of four infect ed patients with serological positive angiostrongyliasis cantonensis (Lane 4: CSF2; 5: CSF3; 7: CSF5; 9: CSF7). Lanes 3 (CSF1), 6 (CSF4), 8 (CSF6), 10 (CSF8), 11 (CSF9) and 12 (CSF10) are negative for ampli fication products by PCR. Lane 1: positive control; 2: negative control (master mix); M: molecular weight markers (100-bp ladder).
