    Isolation of Corynebacterium spp. and Arcanobacterium spp. from a chicken with keratoconjunctivitis
    (Veteriner Hekimler Derneği, 2023) Göçmen, Hüban; Boynukara, Banur
    In this study, a case of Corynebacterium spp. and Arcanobacterium spp. infection is presented from a poultry farm in Tekirdağ city. Necropsy was performed on a chicken brought to Tekirdağ Namık Kemal University Veterinary Faculty Microbiology Department Laboratory with complaints of unilateral severe keratoconjunctivitis, facial oedema and respiratory distress. The pus from the eye of the chicken and other necropsy materials (lung, heart, liver, spleen) were inoculated into appropriate media. Routine biochemical tests were performed to isolate and identify the growing bacteria. In necropsy macroscopic examination, a slight enlargement of the heart was observed with congested areas and multifocal colour changes in the lung, in which the eye was completely closed and filled with pus. While bacterial growth was observed on Columbia agar (5% sheep blood) and Tryptic Soy agar, no growth was observed on Mac Conkey and Eosin Methylene Blue agar from inoculated samples. There was no bacterial growth in the liver and spleen samples. The Gram-positive rods and cocobacilli were detected with Gram staining. As a result of biochemical tests; Corynebacterium spp. and Arcanobacterium spp. from the lung sample, and Corynebacterium spp. from the pus sample of the eye were isolated and identified. These isolations were found to be significant in terms of potential disease risk for poultry species.
