Especies de "Fusarium" aisladas de aguas de cauces fluviales y fondos marinos del litoral del sureste de España

This research presents analytical results for the presence of the Fusarium genus in coastal water samples of the Mediterranean Sea and water from the Andarax Riverbed in the provinces of Granada and Almeria in southeastern Spain. A total of 18 water samples were analyzed from the Andarax River, from which ten species of Fusarium were isolated: F. anthophilum, F. acuminatum, F. chlamydosporum, F. culmorum, F. equiseti, F. verticillioides, F. oxysporum, F. proliferatum, F. solani and F. sambucinum. Five species were isolated from 33 water samples from the Mediterranean Sea: F. equiseti, F. verticillioides, F. oxysporum, F. proliferatum and F. solani. Of the total samples analyzed, 27.45% of the river water samples and 29.41% of the marine water samples presented a minimum of one Fusarium species over a period of almost 12 months of sampling. Considering the samples according to their origins, 77.77% of river water samples and 45.45% of marine water samples presented some Fusarium species. The greater presence of Fusarium in river water could be due to soil particles and organic matter content from run-off of the river banks after rainfall events. The presence of species found in the sea could be the consequence of river water flowing into the sea. Nevertheless, other explanations cannot be excluded.
