Abstract :
Enterococci have been used in food processing for centuries. However, these are all markers of
fecal contamination, with E. faecalis and E. faecium which are the most common species.
Antibiotic resistance of isolated strains was studied by disk diffusion on Mueller-Hinton agar
and virulence was studied by biofilm and hemolysis test.
The main objective of this study was to characterize the virulence of isolated enterococci by
assessing their ability to cause infections in humans or other marine organisms. Laboratory
techniques were used to detect and analyze the specific virulence factors of enterococci.
In addition, antibiotic resistance of enterococci isolated in the marine environment was also
assessed. The purpose of this part of the study was to determine whether these bacteria had
antibiotic resistance mechanisms, which could have important implications for public health
and environment.
The results of the study revealed that enterococci isolated in the marine environment had a
variety of virulence factors, suggesting that they could potentially cause infections for humans.
In addition, several strains of enterococci have shown resistance to antibiotics, indicating the
presence of resistance mechanisms in these bacteria.
In conclusion, this work highlights the importance of understanding the virulence and antibiotic
resistance of enterococci isolated in the marine environment. These results highlight the need
to monitor these bacteria closely in the marine environment, in order to prevent the spread of
antibiotic-resistant strains and minimize risks to public health.
