Abstract
The pathological researches carried out in 1991 aim at the 
identification of the diseases of Mytilus galloprovincialis LMK. at
the Romanian littoral, Mamaia bay. The mussel is a water filtering
marine organism, with an active part in proving the waters it lives
in and interesting for culture; it has been affected by an infection
caused by germs belonging to genera Vibrio and Aeromonas and 15
parasitoses caused by parasite protozoa, worms and crustaceans. The
diseases were more frequent in summer time when a poor quality of 
the marine environment has also been noted. The infections with
Vibrio and Aeromonas have caused low mortalities with the mussel
population in Mamaia bay, while the parasite infestations haven't
caused visible pathological modifications. Among the parasites one
can mention the protozoan Haplosporidium spp. affecting  the gills
and liver-pancreas of mussel.
