Etude de la resistance aux antibiotiques des bacteries isolees de Mytilus galloprovincialis

Abstract

The sensitivity of various aerobic and anaerobic bacterial species isolated from Mytilus galloprovincialis to different types of antibiotics. Thus, sensitivity of 50 aerobic and 20 anaerobic species was tested to 15 antibiotics including (betalactams, aminosids, cephalo porins, phenicols, cyclins, macrolids, nitrofurans, sulfamids, rifamycins). According to results obtained, all strains tested demonstrate resistances profiles to 3 to 12 antibiotics tested. Multi resistant profiles to 12 different antibiotics were detected for the anaerobic species (Propioni acnes). For the main aerobic species isolated, Aeromonas hydrophila we described more than 6 different antibiotypes. According to these results, it seems that the multi resistant antibiotic bacteria were well spread in Mytilus galloprovincialis brought from natural Tunisian lagoon ecosystems (Lagoon of Bizerta).
