| Pullorum disease (PD) is one of the most common diseases in the world, with devastating consequences. In the chicken sector, there have been financial losses. It is brought on bySalmonella enteric subspecies serovar Gallinarum biovar pullorum; definitive detection requires culture followed bybiochemistry analysis and serotyping. This study aimed to verify the presence of bacteria by culture, biochemical characterization, PCR assay, and sequencing. One hundred samples were collected from 12 broiler chicken flocks of different ages for 8districts of Baghdad province, including cloacal swabs (65), visceral organs (15), and dropping (20). Salmonella colonies were identified byselective culture broth and agar with biochemical description for 75% of the total samples, with a higher incidence in visceral organs than dropping and cloacal swabs. ،The Sequencing and phylogenetic tree analysis of 16S rRNA gene for representative Salmonella isolates. The presence of Salmonella Pullorumisolates in global genetic strains; was revealed a matching NCBI isolates similarity of 99.02% with (MF445124.1) and 98% with (MH352164.1), respectively. In the current state of molecular and genetic research, phlyogentic research announced the real presence of SalmonellaPullorumin Baghdadprovince's broiler chicken, also showing the phylogentic characteristics and links to some global isolates. The detection of SalmonellaPullorumin broiler flocks of the current study extent of health risks to other uninfected birds present in the free range. | ||
