[Investigation of fungal populations in seven ochratoxin A contaminated root herbs].
OBJECTIVE
To determine the fungal populations in seven ochratoxin A contaminated root herbs in Jiangxi province, and investigate the mycoflora associated with mycotoxin contamination in the root herbs.


METHODS
Single spore isolation was used to obtain the strains from root herb's surface. Fungi were identified according to morphology and molecular evidence.


RESULTS
Seventeen fungal species belonged to six isolated genera, nine species of Penicillium, three species of Aspergillus, two species of Fusarium and three other species were identified.


CONCLUSIONS
Fungal contamination of root herbs demands urgent attention, ochratoxin A producing fungi possess specific distribution on herbs.
