¹ Department of Veterinary Hygiene and Management, Faculty of Veterinary Medicine, Cairo University, 12211, Egypt - Zinc oxide (ZnO), Flumequine, and Tiamulin nanoparticles were designed to target Mycoplasma gallisepticum (MG) without adversely affecting egg-hatching potential. 3,000 eggs were selected from 3,500 of Hy-Line breeder flock which were divided into 5 equal groups (600 eggs each) as detailed below: Group A (infected by MG and sanitized by using ZnO nanoparticles); Group Bf (infected by MG and sanitized by using Flumequine nanoparticles); Group Bt (infection by MG and sanitized by Tiamulin nanoparticles); Group C (infected by MG, serving as the positive control); Group D (uninfected and untreated, serving as the negative control). The findings revealed a statistically significant reduction (P<0.05) in colony-forming units per millilitre (CFU/mL) of MG and Total Bacterial Colony Count (TBCC) in groups: A, Bf and Bt after 5 days of treatment as compared to group C. The treatments exhibited notable bactericidal properties while allowing for normal embryo development, hatching, and mortality rates. Eggs treated with these antibacterial agents experienced a significant decrease (P < 0.001) in embryonic mortality during incubation. ZnO NOs, Flumequine, and Tiamulin nanoparticles exhibit promise in preventing Mycoplasma gallisepticum -induced hatchery infection.
