Abstract AR
أدى اكتشاف قدرة البكتيريا على التواصل مع بعضها البعض إلى إحداث تغير كبير في إحساسنا بعديد من الكائنات وحيدة الخلية التي تعيش في عالمنا.
تستطيع البكتريا أن تتواصل فيما بينها مستخدمة مركبات صغيرة الوزن الجزيئي يطلق عليها "محفزات ذاتية" (Autoinducers).
يتم ذلك من خلال نظام إشارات يعتمد على كثافة الخلايا يعرف ب "الحس الجماعي" (Quorum sensing QS).
المكونات الرئيسية التي تشكل دورة الحس الجماعي هي نوعان من الجينات المنظمة يطلق عليهما LuxI و LuxR إلى جانب لأوبرون Operon المستهدف و هذا عادة ما يتكون من جينات مختلفة.
Abstract EN
The discovery that bacteria are able to communicate with each other has changed our perceptions of many single organisms that inhabit our world.
Bacteria cells communicate among themselves using low-molecular-weight compounds called autoinduceres, through what is known as quorum sensing (QS), a cell density-dependent signaling system.
The principle components of the QS circuit are ; two regulatory genes LuxI and LuxR and the target operon which are usually composed of different genes.
Quorum sensing enables bacteria to coordinate their behaviour which involved in some bacterial activities.
Overall bacteria may use QS for their growth, survival and virulence in food environments.
So, targeting QS may be an effective approach against bacterial proliferation and virulence. Food spoilage is a complex process, excessive amounts of foods are lost due to the microbial spoilage.
Several proteolytic, lipolytic, chitinolytic and pectinolytic activities associated with the deterioration of foods are regulated by QS.
Several types of autoinducers (AI), have been detected in different spoiled food products.
So, disrupt the QS circuit plays a major role in controlling microbial gene expression related to human infection and food spoilage.
The QS inhibitors can be developed that are targeted toward inhibiting the synthesis of the autoinducer molecules or block these signaling systems.
Thus, it can lead to prevention of food spoilage, biofilm formation and food born pathogens.
