Effects of bone cement loaded with teicoplanin, N-acetylcysteine or their combination on Staphylococcus aureus biofilm formation: an in vitro study

Öz:
Amaç: Bu çalışmada sadece teikoplaninin, sadece N asetil sistein (NAC)'in veya her iki bileşenin kombinasyonunun kemik çimentosuyla karıştırılmasının antibiyofilm etkileri gösterildi.Gereç ve yöntemler: Her grupta farklı içeriğe sahip kemik çimentosu ile hazırlanan altışarlı çimento kalıplar kullanılarak toplam dört grup oluşturuldu. Grup 1 (kontrol grup): Herhangi bir ilaç katılmaksızın sadece çimento. Grup 2: 40 g çimento, 400 mg teikoplanin. Grup 3: 40 g çimento, 6 g NAC. Grup 4: 40 g çimento 6 g NAC, 400 mg teikoplanin. Tüm çimento kalıpları Stafilokokkus aureus ile 48 saat 36.5 °C'de enfekte edildi. Bakteri kolonileri seri dilüsyon yöntemiyle sayıldı. Bakteriler taramalı elektron mikroskobik (TEM) görüntüler kullanılarak sayıldı.Bulgular: Bakteri kolonisi sayıları grup 1'de 5.83±1.60 [ortalama koloni oluşturan birim (kob) x 105±standart sapma (SS)], grup 2'de 0.12±0.56, grup 3'te 0.11±0.65 ve grup 4'te 0.01±0.001 idi. Grup 1 ile tüm diğer gruplar arasında (p<0.05) ve grup 4 ile tüm diğer gruplar arasında anlamlı farklılık bulundu (p<0.05). TEM analize göre, bakteri sayıları (ort.±SS) grup 1, 2, 3 ve 4'te sırasıyla 1.88±0.45, 0.75±0.26, 0.21±0.22 ve 0.13±0.25 idi. Grup 1 ile tüm gruplar arasında (p<0.05) ve grup 4 ile tüm gruplar arasında anlamlı farklılık bulundu (p<0.05).Sonuç: N asetil sistein, teikoplanin ve bunların kombinasyonu kontrol grubuna göre biyofilm oluşumunu anlamlı olarak azalttı. Ayrıca, NAC ve teikoplanin kombinasyonu en yüksek antibiyofilm etkisine sahipti

Objectives: This study aims to demonstrate the antibiofilm effects of teicoplanin alone, N-acetyl cysteine (NAC) alone, or combination of both compounds when mixed with bone cement.Materials and methods: A total of four groups were formed by using six cement samples in each, prepared with bone cement having different contents in each group. Group 1 (control group): cement alone without any drugs added. Group 2: 40 g cement, 400 mg teicoplanin. Group 3: 40 g cement, 6 g NAC. Group 4: 40 g cement, 6 g NAC, 400 mg teicoplanin. All cement samples were infected with Staphylococcus aureus for 48 hours at 36.5 °C. Bacterial colonies were then counted by serial dilution method. Bacteria were counted using scanning electron microscopic (SEM) images.Results: Counts of bacteria colonies were 5.83±1.60 [mean colony forming unit (cfu) x 105±standard deviation (SD)] in group 1, 0.12±0.56 in group 2, 0.11±0.65 in group 3, and 0.01±0.001 in group 4. Significant difference was found between group 1 and all other groups (p<0.05), and between group 4 and all other groups (p<0.05). According to SEM analysis, counts of bacteria (mean±SD) were 1.88±0.45, 0.75±0.26, 0.21±0.22, and 0.13±0.25 in groups 1, 2, 3, and 4, respectively. Significant difference was found between group 1 and all other groups (p<0.05), and between group 4 and all other groups (p<0.05).Conclusion: N-acetyl cysteine, teicoplanin, and their combination significantly reduced formation of biofilm compared to the control group. Also, combination of NAC and teicoplanin had the highest antibiofilm effect
