Avian H9N2 influenza virus is a significant pandemic pathogen widely distributed throughout the world. This virus can infect different species and cause zoonotic infections. Ownership of pets has been identified as a contributory factor to the transmission of infections to humans. In light of significant public health issues, this research investigated the prevalence of the H9N2 avian influenza virus in cats in the southeastern region of Iran. 75 feline blood samples were obtained from various sources, including the veterinary clinic of Shahid Bahonar University in Kerman, private clinics, and stray cats within the city. The results showed that 49 of the 75 feline samples (65.33%) tested positive for the presence of H9N2 antibodies. Statistical analysis revealed that raw food diets, outdoor living environments, and contact with other animals were identified as key contributors to increased seropositivity rates. This study demonstrates the potential risk factors for H9N2 exposure in the feline population and could inform future strategies to mitigate transmission risks in both domestic and stray cat populations.

In this study, the Hemagglutinin inhibition (HI) and ELISA testes were checked and comprised with CBC in challenge with Infectious Bursal Disease (IBD) and Avian Influenza (AI) sub type H9N2 viruses in ostrich. Eight ostrich chicks one months were prepared and divided randomly in two equal groups. Group 1 received IBD virus and group 2 received AI (H9N2) virus. Then on 2 days prior to challenge and 11 and 21 days post-challenge sera samples and on 2 days prior to challenge and 3, 11 and 21 days post-challenge blood smears were prepared from group 1 and on 2 days prior to challenge and 7 days post-challenge sera samples and on 2 days prior to challenge and 7 and 18 days post-challenge blood smears were prepared from group 2. The results were evaluated and analyzed by Sigma Stat software. In group 1, antibody titer significantly increased on 21 day post-challenge compared with 2 day prior to challenge and 11 day post-challenge but CBC didn’t show a significant change in after and before the challenges. In group 2, antibody titer significantly increased on 7 day post-challenge compared with 2 day prior to challenge but CBC didn’t show a significant change in before and after the challenges. The present study show that Infectious Bursal Disease virus infected the ostrich but didn’t any effects on CBC. HI and ELISA testes respectively are useful technique for detection of IBD and AI antibody after challenges in ostrich.
