I am Dr. Khald Blau, an assistant prof. in the Botany Department (Microbiology) - Faculty of Sciences - Gharyan University, Libya. I hold a Doctor of Philosophy (Ph.D.) degree from the Department of Life Sciences (Microbiology) at the Technical University of Braunschweig, Germany, where I specialized in the fields of Bacteriology and Molecular Biology. My research primarily focuses on the ecological and evolutionary dissemination of antimicrobial resistance within agroecosystems. I have a keen interest in studying the structure, diversity, and ecology of bacterial communities in various environmental sources, including soil, the rhizosphere, and phyllosphere of plants. One of my key areas of expertise involves the detection and characterization of antimicrobial-resistant bacteria and human pathogens, particularly coliforms such as Escherichia coli, Klebsiella pneumoniae, and Enterobacter spp. My research delves into understanding the mechanisms of resistance, gene transfer, and the impact of antimicrobial usage on the emergence and spread of resistant bacteria. My other research interests include investigating the prevalence, diversity and genetic characteristics of Clostridioides (Clostridium) difficile in diverse environmental sources contaminated with faecal matter. My research endeavors focus on exploring the presence of this pathogen in environments such as animal manure and faeces, sewage, soil, sewage sludge, surface water, biogas plants, and thermophilic digesters.
