However, few studies have reported the changes in pig lung microorganisms during respiratory infection. Therefore, we aimed to explore the differences in lung environmental microorganisms between healthy piglets and piglets with respiratory diseases. Histopathological changes in lung sections were observed in both diseased and healthy pigs. Changes in the composition and abundance of microbiomes in alveolar lavage fluid from eleven 4-week-old Chinese Kele piglets (three clinically healthy and eight diseased) were studied by IonS5™ XL sequencing of the bacterial16S rRNA genes. Histopathological sections showed that diseased pigs displayed more lung lesions than healthy pigs. Diseased piglets harbored lower bacterial operational taxonomic units, α-diversity, and bacterial community complexity in comparison t can exist in the respiratory system of diseased pigs and provide a potential basis for clinical treatment. Influenza type A virus infections are still one of the major concerns for the health of humans and various species of domestic and companion animals. Wild birds play an essential role in the transmission cycle of the virus. Regularly monitoring the spread of the virus is a significant step in its mitigation. Highly pathogenic avian influenza viruses, including H5N1 and H5N8, have been reported in birds in the Arabian Peninsula, including Saudi Arabia, in recent decades. This study aimed to evaluate the immune status of birds, domestic and companion animals for Influenza type A virus in Eastern Province of Saudi Arabia. We collected 195 serum samples from dromedary camels, sheep, goats, native breed chickens, doves, dogs, and cats. We tested these sera for the presence of specific antibodies against influe
