Alternative Title
للمضادات الحيويةMytilus galloprovincialis دراسة مقاومة بكتيريات المحار
Study of the antibiotic resistance of bacteria isolated from Mytilus galloprovincialis
Abstract
L’étude des résistances vis-à-vis de différentes substances antibiotiques pour des espèces bactériennes (aérobies et anaérobies) isolées chez Mytilus galloprovincialis a été réalisée par la méthode standard de l’antibiogramme. Ainsi, 50 souches bactériennes aérobies et 20 souches anaérobies appartenant à plus de 25 espèces différentes ont été isolées et testées. Les résultats obtenus montrent des profils à plusieurs résistances vis-à-vis des différentes familles d’antibiotiques testés. Les résultats obtenus révèlent des profils à 12 résistances différentes notamment chez l’espèce anaérobie (Propioni acnes). Aussi, chez l’espèce aérobie pré dominante ( Aeromonas hydrophila) nous avons mis en évidence au moins 6 antibiotypes différents. Ces résultats montrent la prépondérance de bactéries multirésistantes aux antibiotiques hébergeant dans la moule Mytilus galloprovincialis prélevée d’un milieu naturel (la lagune de Bizerte).
قمنا بدراسة مقاومة مجموعات من أنواع البكتيريات الهوائية واللاهوائية تم عزلها من محار)Mytilus galloprovincialis(، للمضادات الحيوية من مختلف الأصناف. ولقد تم عزل ودراسة 70 من مختلف الأجذال البكتيرية والتي تم تعريفها بالطرق البيوكيميائية. وقد أثبتت النتائج المتحصل عليها وجود رسوم طيفية ذات مقاومات متعددة لـ 12 مضاد حيوي لدى البكتيريا اللاهوائية من نوعPropioni acnes. كما قمنا بعزل مكثف للبكتيريا من نوع Aeromonas hydrophila، وثبت لدى هذا النوع من البكتيريا وجود أكثر من ستة رسوم طيفية مختلفة. وتبين هذه النتائج كثافة تواجد البكتيريات متعددة المقاومة لدى المحارMytilus galloprovincialis المتأتي من بحيرة بنزرت، وذلك يشمل كل أنواع البكتيريا المعزولة (أكثر من 25 أصناف مختلفة).
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)..
