Etude génétique et antibiogramme chez l’espèce aviaire dans la wilaya d’Oran

Abstract

The antibiogram is a laboratory technique measuring in vitro the sensitivity of a bac- terial strain to an antibiotic and making it possible to predict with a low risk of error a suc- cess or therapeutic failure. The antibiogram is always carried out on a bacterial strain iso- lated by culturing a clinical sample, identified and whose role in the infectious process is strongly suspected. The antibiogram is useless on a commensal or contaminating germ. The purpose of the antibiogram is to characterize the acquisition of acquired re- sistance to antibiotics. Only antibiotics known to be naturally active on the bacterial spe- cies in question are tested. Its results make it possible to modify the first-line prescription. It is also carried out as part of the epidemiological surveillance of antibiotic resistance. It then makes it possible to define the status of a bacterial species with respect to a molecule. The updated spectra make it possible to set up a first-line probabilistic treat- ment. The antibiogram is not necessary when the bacterial species responsible for the in- fection is usually sensitive to the standard treatment. In this work, we were able to find antibiotics that target and kill bacteria causing serious disease in poultry houses. Using Antibiogram technology, we have been able to target bacteria and reduce var- ious diseases that have caused the death of significant numbers of poultry.
