I studied biology at the Eberhard Karls University Tübingen (Germany) with a focus on molecular biology, virology and microbiology. Having become interested in immunology, I decided to perform my Diploma thesis and subsequently my PhD thesis at an immunological institute and thus joined the Institute of Immunology at the Vetmeduni Vienna. more

TL;DR: Bacterial re-isolation and counts of colony forming units (CFU) showed that G. anatis colonization pattern in various organs, and the numbers of bacteria in trachea were not affected by immunosuppression, however, the treatments acutely increased CFU counts derived from the spleen, which demonstrates that chemically induced immunOSuppression intensifies systemic multiplication of G. Anatis in chickens. (via Semantic Scholar)
