“…Isolates of P. pseudodelicatissima from the 1992 bloom did not produce detectable amounts of domoic acid (Lundholm et al, 1994), although Martin et al (1990) presented evidence to the contrary for a strain isolated from the Bay of Fundy, eastern Canada. The first confirmation of domoic acid production in a European Pseudo-nitzschia species was reported by Lundholm et al (1994), who showed that some isolates of P. seriata from Danish coastal waters produced the toxin.…”

“…P. australis Frenguelli (= P. pseudoseriata Hasle) was responsible for the death of cormorants and pelicans feeding on contaminated anchovies on the west coast of North America (Buck et al, 1992;Fritz et al, 1992;Garrison et al, 1992). Another species, P. pseudodelicatissima (Hasle) Hasle, has been linked to toxic events in the Bay of Fundy, eastern Canada (Martin et al, 1990), and has also been found throughout western Europe where it bloomed along the coast of Denmark in 1992 (Lundholm et al, 1994) and in Kiel Bay, western Baltic Sea (Hansen & Horstmann, 1993). Although this species is reported to produce domoic acid (Martin et al, 1990), isolates from the bloom in Danish coastal waters were not toxic (Lundholm et al, 1994).…”

Biological monitoring in the Dutch Wadden Sea between November 1993 and July 1994 revealed Pseudo-nitzschia-like pennate chain-forming diatom species with cell numbers ranging from 102 to 105 per litre. Cultured isolates and field samples were examined by electron microscopy, which revealed the majority to be Pseudo-nitzschia pungens. This species dominated over other diatoms in the phytoplankton population during November 1993 and at the end of June 1994. At the beginning of June 1994, P. fraldulenta was also present; occasionally, P. ddicatissima was observed. One isolate showed the characteristic morphology of P. multiseries. Species-specific polyclonal antibodies and large-subunit (LSU) rRNA-targeted oligonucleotides for North American strains of P. multiseries and P. pungens applied to the European isolates, confirmed species designations based on electron microscopy. The isolate of P. multiseries from the Dutch Wadden Sea produced domoic acid; after 55 days of growth about I9pg per cell was measured. This is the first report of a domoic acid-producing P. multiseries isolated from European coastal waters.

“…En mer le phytoplancton toxique, ou susceptible de l'être, de nos cotes est essentiellement représenté par des dinophycées appartenant aux genres : Dinophysis, Gyrodinium, et Atexandrium ainsi que par une prymnésiophycée, Phaeocystis (SOURNIA et al 1990). Les mêmes genres ont tous des représen -tants toxiques dans le monde entier, mais il existe aussi des diatomées toxiques appartenant au genre Nitzschia produisant de l'acide domoïque, qui se concentre dans les coquillages comme la toxine de Dinophysis (MARTIN et al 1990). Un facteur neurotoxique a été trouvé associé à la cyanobactérie Trichodesmium, Oscillaire planctonique marine (HAWSER et al 1991) et une cytotoxine est présente chez Lyngbya (ARMSTRONG étal.…”

La toxicité du phytoplancton est un problème dont l'importance est grandissante en France comme en Europe. Cette toxicité se manifeste surtout lors de l'ingestion de cyanobactéries formant des fleurs d'eau superficielles liées à l'eutrophisation. Microcystis aeruginosa est l'espèce la plus fréquemment incriminée, mais 75 % des souches de cyanobactéries d'eau douce seraient des toxiques potentielles. Lorsque des clones sont isolés d'un plan d'eau dans lequel des manifestations de toxicité ont été observées, des souches toxiques et non toxiques sont obtenues. La connaissance des conditions d'expression de la toxicité représente un sujet important actuellement peu étudié. Un mammifère peut mourir s'il passe dans son sang 0,07 mg de toxine de Microcystis par kg de son poids. En pratique, de nombreux cas de morts de bétail ont été recensés. Les toxines qui causent des accidents sont des endotoxines non rejetées par les cellules vivantes, mais libéré au cours de leur lyse. Ceci explique que des cas d'intoxication humaine par l'intermédiaire de l'eau de boisson ont pu être observés. On distingue principalement : des microcystines, hépatotoxines produites par diverses cyanobactéries dont Microcystis et Oscillatoria, et des anatoxines, neurotoxines produites par des Anabaena. Certaines cyanobactéries produiraient un mélange des deux formes. En sus du test de toxicité classique sur la souris, plusieurs autres tests existent. L'analyse est généralement réalisée par chromatographie liquide à haute pression. Des produits actifs synthétisés par des cyanobactéries possèdent une fonction antibiotique et sont susceptibles de jouer un rôle dans le comportement des espèces et leur dominance ou de les protéger contre le broutage. Ces produits seraient des exotoxines différentes des précédentes.The aim of the paper is to present in the French language the international knowledge related to freshwater cyanobacterial toxins, a problem of great significance in our European countries but largely unknown by people in France. An analytical review of a selection of works chosen from the extensive existing literature is presented. At the present time, the mains works come from : U.S.A., with CARMICHAEL and coworkers, continuing the researchs from CORHAM; Scotland, with CODD; Scandinavia with ERIKSSON, LINDHOLM; and Japan with WATANABE, HARADA, but also many others scientists.In freshwater, poisoning is typically associated with the ingestion of the cyanobacteria appearing in large amount, at the surface of some water bodies, and called water blooms. Many cases of livestock death (concerning sheeps, calves but also adult oxen and horses), associated with the consumption of such water blooms are reported, also, deaths of wild mammals (muskrats, and hogs), birds (ducks, geese), fishes, invertebrate, and human illness following bathing are known. But, because toxins are not destroyed by conventional sand filtration treatment, human illness may also arise from drinking water taken out from an impoundment with a cyanobacterial bloom. Cases are kno...

“…There is also an indication in the literature that several other common diatom species may produce domoic acid e.g., Fragilaria spp (Pauley et al 1993), Amphora Coffeaeformis (Maranda et al 1990), Nitzchia pungens .f. multiseries, N.pseudo delicatissima and N. pseudo seriata (Pseudonitzchia australis Frenguelli) (Subba Rao et al 1998, Martin et al 1990, Work et al 1992. The production of DA has been identified in nine species of Pseudonitzschia and one species of Nitzschia (Bates et al 1989;Bates, 2000).…”

Harmful, toxic algae are now considered as one of the important players in the newly emerging environmental risk factors. The apparent global increase in harmful algal blooms (HABs) is becoming a serious problem in both aquaculture and fisheries populations. Not only has the magnitude and intensity of public health and economic impacts of these blooms increased in recent years, but the number of geographic locations experiencing toxic algal blooms has also increased dramatically. There are two primary factors causing HABs outbreaks. The natural processes such as upwelling and relaxation, and the anthropogenic loading resulting in eutrophication. However, the influence of global climate changes on algal bloom phenomenon cannot be ignored. The problem warrants development of effective strategies for the management and mitigation of HABs. Progress made in the routine coastal monitoring programs, development of methods for detection of algal species and toxins and coastal modeling activities for predicting HABs reflect the international concerns regarding the impacts of AL-GHELANI, H.M., ALKINDI, A.Y.A, AMER, S. AND AL-AKHZAMI, Y.K. 2HABs. Innovative techniques using molecular probes will hopefully result in development of rapid, reliable screening methods for phycotoxins and the causative organisms.
