A doctoral thesis was discussed at the College of Veterinary Medicine at Al-Qadisiyah University, entitled “Characterization of the virulence and antibiotic resistance of isolates of Staphylococcus species from humans and some animals.” The thesis was presented by researcher Mohammed Hussein Amer and supervised by Prof. Dr. Alaa Abdul-Kazem Jawad.

The thesis aimed to characterize the virulence determinants and antibiotic resistance patterns of Staphylococcus species isolated from humans and some animals, using both traditional and molecular approaches. This was done to better understand their pathogenicity, resistance mechanisms, and zoonotic significance.

Main Conclusions: Genes and antibiotic-resistant Staphylococcus isolates can be successfully identified using the polymerase chain reaction (PCR) technique.  Its advantages, compared to traditional detection techniques, include increased speed and effectiveness. This study also included multiple distinct types of staphylococcus.

The most important recommendations are enhanced surveillance programs and the establishment of continuous monitoring systems for MRSA in humans and animals to detect emerging resistant strains, especially MRSA and multidrug-resistant strains. It also includes the judicious use of antibiotics and the implementation of strict antibiotic management programs in hospitals, veterinary clinics, and livestock farms to reduce the misuse and overuse of antimicrobial agents.
