Abstract:
Pathogens are an important and significant hazard for human and animal health. In recent years, antibiotics are used to treat different types of infection caused by bacterial agents. In veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission ofdisease, but the adverse effects of drugs have always been a major concern. There is scantly information available about the safety and pathological alterations of florfenicol drug in embryonated eggs. The objective of this study was to investigate using of various dosages of florfenicol solution for in ovoadministration in chicken embryo. Fertile chicken eggs were divided into four equal treatment groups as follows: group 1: no injected group. Group 2: phosphate buffered saline-injected group; whose individuals were injected with phosphate buffered saline. Groups 3 and 4 whose individuals were injectedwith florfenicol injectable solution at a dosage of 20 and 30 mg per Kg egg-weight, respectively. Embryos were re-incubated post-treatment and allowed to develop until day 18 after which; they were examined for macroscopic and microscopic lesions. Results showed that embryos were normal in alltreatment groups. Microscopically, no lesions were also diagnosed in tissues. Based on macroscopic and microscopic findings, it is concluded that florfenicol at above-mentioned concentration is not toxic for the chicken embryo. So, florfenicol egg-injection can be used to eliminate pathogens and prevention of egg transmission of the disease without any adverse effect.
