OverviewAI-generated summary
Saeed Khan is a research microbiologist at the National Center for Toxicological Research. His work investigates microbial resistance mechanisms and molecular characterization of bacterial isolates. He has published research on the detection and characterization of virulence genes and integrons in *Aeromonas veronii* from catfish, as well as the biochemical and molecular characterization of tetracycline-resistant *Aeromonas veronii* isolates from the same source.
Khan's research has also focused on identifying multidrug-resistant bacteria, including *Salmonella typhimurium* DT104 using multiplex polymerase chain reaction, and multidrug-resistant *Klebsiella spp.* isolated from shrimp. He has investigated the transfer of antibiotic resistance, such as erythromycin resistance from poultry to human clinical strains of *Staphylococcus aureus*, and the molecular characterization of multidrug-resistant *Enterococcus spp.* from poultry and dairy farms, including the detection of virulence and vancomycin resistance gene markers.
His publication record includes studies on RNA isolation methods from bacteria and has explored the potential of nanoparticles for biological applications. Khan leads a research group and collaborates with several researchers at the National Center for Toxicological Research, including Kidon Sung, Miseon Park, Ohgew Kweon, and Angel Paredes. He is recognized as a highly cited researcher with an h-index of 21 and over 1,300 citations across his 77 publications.
