AIMS: The purpose of these experiments was to determine whether the heart and lungs of young chicks harboured bacteria. METHODS AND RESULTS: Samples of the heart and lungs were aseptically removed from chicks on scheduled sampling days. Experiment 1 showed that of the 360 birds evaluated during the late embryonic and early post-hatching periods, only 10.8% harboured bacteria in the heart, lungs, and heart and lungs simultaneously. Experiment 2 suggested that bacteria in these organs were transient. Twenty-three bacterial species were found in the hearts whereas 30 were found in the lungs. Experiment 3 showed that only 1.4% of embryos harboured bacteria in the yolk, albumen, heart and lungs whereas 12.9% of the embryos had bacteria in the air cell. CONCLUSIONS: During the post-hatching period, there was a higher incidence of bacterial isolation in the heart and lungs, whilst during the embryonic development period, there was a lower incidence of bacterial isolation from these two organs. Results suggested that the heart and lungs do not have a residual bacterial flora; rather, opportunistic bacteria occasionally pass through these tissues. SIGNIFICANCE AND IMPACT OF THE STUDY: These experiments proved that bacteria could be isolated in the heart and lungs of healthy chicks reared from E17 to 3 weeks of age. |
