To give morphological assessment of catheter-associated infection model in laboratory mice in conditions of immunosuppression caused by introduction of cyclophosphamide. Materials and methods. Modeling of catheter-associated infection for morphological assessment of changes in the surrounding tissues was carried out. Animals were implanted catheters with preliminary grown staphylococci biofilms; they were also once and repeatedly introduced bacterial suspensions into the tissues surrounding the catheter. Cellular composition of inflammatory infiltrate and microbial colony volume were assessed during three days. Results. Restrictive shaft round the catheter consisting of fibrin and cellular elements of inflammatory infiltrate with different thickness and composition depending on observation terms and experimental peculiarities was formed. Immunosuppression causes more marked growth of staphylococcus colonies and less pronounced inflammatory response than in case of introducing staphylococcus cultures without cyclophosphamide.</p></abstract><trans-abstract xml:lang="ru"><p>Среди причин астмоподобных заболеваний выделяют редкую врожденную сосудистую патологию - сосудистое кольцо трахеи, клинически проявляющуюся затруднением дыхания (иногда - в сочетании с дисфагией).
