Dr. Iyad Qasim Mahdi Al-Maki, a faculty teacher at the Faculty of Pharmacy, published a paper entitled "A new methodology to assess antimicrobial resistance of bacteria in coastal waters; Pilot study in a Mediterranean hydrosystem in Comptes Rendus Geoscience For the European publishing house ELSEVIER with an impact factor of 1.541. Al-Maki said his research included the study of the resistance of bacterial communities in water. Is a major concern for public health at the moment where it is considered an appropriate medium in the exchange of antibiotic-resistant genes between strains Different bacterial, so the iron has developed a new way to evaluate the bacterial community's resistance to antibiotics by linking different concentrations. Antibiotics (cefotaxime ceftazidime and tetracycline) inhibitor of bacterial community growth (community inhibitory concentration) with the abundance of bacterial varieties of that community this method was applied to the salty and fresh environments in France, and showed The results show that low antibiotic concentrations clearly reduce the abundance of bacterial species, as the results show that the bacterial community is in the water. Saline is more diverse and less affected by antibiotics than freshwater communities.
