Resumen:
Background In the present research, challenges arose when many reports
have been published on the poisoning of humans due to the ingestion of
crops of Crataegus plants contaminated with cyanobacterial toxins. The
discovery of several poisonings around agricultural zones prompted us to
study the toxic compounds in a strain of Neowestiellopsis which is the
most abundant in the agricultural zones of Kermanshah province of Iran,
using a polyphasic approach. Molecular procedure was followed to study
these strains deeply. Material and methods To elucidate their systematic
position, besides the 16S rRNA gene, the analyses of molecular toxicity
markers, namely nos, mcy G, mcy D and internal transcribed spacer (ITS),
were also used. Results Based on the results, for the first time, we
record the presence of a gene cluster coding for the biosynthesis of a
bioactive compound (Nostopeptolides) that is very rare in this family
and the presence of toxic compounds (microcystin), which might account
for the poisoning of humans. Conclusions This case is the first
observation of a toxic soil strain from the genus Neowestiellopsis from
agricultural fields in Iran.
