Abstract
Between January and October 1994, we contucted research aiming at
determining the bacterial contamination of the mussel (Mytilus 
galloprovincialis Lmk) inhabiting the coastal zone in Mamaia Bay, 
one of the most polluted Romanian marine littoral areas (owing to 
the discharges of the industrial wastes from Midia-Navodari, town
sewages of Constanta North and Mamaia beach). Each month, either
mollusc potentially pathogenous bacteria (Aeromonas, Vibrio,  
Pseudomonas, Cytophaga, Flexibacter) and mollusc consumer potentially
pathogenous germs (sulphite deoxiding bacteria, coliform bacteria,
streptococci) were found in mussel meat. The maximum contamination
was noted in April, at a water temperature of 14 degree C, when the
total number of heterotrophic germs was of 800,000-1,000,000/g of
mussel, sulphite deoxiding bacteria , 45,000-48,000/g of mussel,
coliform bacteria, 16,090/g, and the bacteria Aeromonas and Vibrio  
reached 40,000/g of mussel and 30,000/g of mussel respectively.
Key words: pathogenous bacteria, diseases, bacterian contamination, 
           incubation, inseminations
