First report of Pseudo-nitzchia calliantha Lundholm, Moestrup& Hasle 2003,a new potentially toxic species from Turkish coasts

Türkiye kıyılarından potensiyel olarak toksik, yeni bir tür kaydı, Pseudo-nitzschia calliantha Lundholm, Moestrup & Hasle 2003. Diatomlardan Pseudo-nitzschia'nm bazı türlerinin dünyanın bir çok bölgesinde insanlar da dahil yüksek organizasyonlu organizmaların ölümlerinden sorumlu olduğu ve bir nörotoksik aminoasit olan domoik asit'i ürettiği bilinmektedir. Bu çalışmada, elektron mikroskobu kullanılarak, potansiyel olarak toksik olabilecek bir Pseudo-nitzschia türü olan P. calliantha, Türkiye'nin Karadeniz kıyılan için ilk kez rapor edilmiştir. P. calliantha'nın tanımlanması morfolojik incelemelere dayanarak yapılmıştır.

Türkiye kıyılarından potansiyel olarak toksik,yeni bir tür kaydı, Pseudo-nitzschia calliantha Lundholm, Moestrup& Hasle 2003

Several species of the diatom Pseudo-nitzschia H. Peragallo in H. & M. Peragallo, 1897-1908 are known to produce domoic acid (DA), a neurotoxic amino acid that has been shown to be responsible for deaths of higher trophic-level organisms, including humans, in many areas around the world. In this study, one of the potentially toxic Pseudo-nitzschia species, P. calliantha, is documented for the first time from the Turkish Part of the Black Sea using transmission and scanning electron microscopy. P. calliantha is described based on morphological data.
