Abstract

Amaç: Meme kanserinin tedavisinde kullanılan tamoksifenin (TAM), antimikrobiyal ajan olarak önemli bir etkisi daha vardır. Bu çalışmanın amacı, TAM’nin insan ağız boşluğunda bulunan bakterilere karşı antibakteriyel etkinliğini araştırmaktır. Gereç ve Yöntemler: İnsan ağız boşluğunda bulunan bakteriler sağlıklı bireylerden izole edildi. İzole edilen bakterilere karşı farklı TAM konsantrasyonları test edildi. Ek olarak, TAM’nin bakterisidal ve bakteriyostatik etkileri de belirlendi. Bulgular: İzole edilen 23 bakteriden Gram-negatif bakterilere kıyasla daha fazla sayıda Gram-pozitif bakterinin, düşük TAM konsantrasyonlarına yüksek oranda duyarlı olduğu saptandı. Gram-pozitif bakteri olan Kytococcus sedentarius ve Gram-negatif bakteri olan Pseudomonas stutzeri, TAM’nin bakteriyostatik etkisiyle inhibe edilebilmeleri için yüksek bir minimum inhibitör konsantrasyon değerine (2,5 mg/mL) ihtiyaç duydukları saptandı. TAM’ye direnç, üç Gram-pozitif ve dört Gram-negatif bakteri suşunda da gözlenmiştir. Sonuç: TAM, özellikle Gram-pozitif bakteriler olmak üzere ağız boşluğunda bulunan bakterilere karşı potansiyel antibakteriyel etki göstermiştir. Bu etki çoğunlukla bakteriyostatiktir. Bu çalışmada aynı zamanda TAM’ye karşı bakteriyel dirençte gösterilmiştir. Anahtar kelimeler: Bakteri, ağız boşluğu, tamoksifen, Gram-pozitif, Gram-negatif

Özet

Objectives: Tamoxifen (TAM), which is used for treating breast cancer, has exhibited another important function as an antimicrobial agent. The objective of this study is to investigate the antibacterial action of TAM against the bacteria present in the human oral cavity. Materials and Methods: The bacteria present in the human oral cavity were isolated from healthy individuals. Different concentrations of TAM were tested against the isolated bacteria. Additionally, bactericidal and bacteriostatic effects of TAM were also determined. Results: Out of 23 isolated bacteria, a greater number of Gram-positive bacteria were highly susceptible to the low concentrations of TAM than Gram-negative bacteria. Kytococcus sedentarius, which is Gram-positive bacterium, and Pseudomonas stutzeri, which is Gram-negative bacterium, needed a high minimum inhibitory concentration value of TAM (2.5 mg/mL) to be inhibited by TAM’s bacteriostatic action. Resistance to TAM was also observed in three strains of Gram-positive and four strains of Gram-negative bacteria. Conclusion: TAM has shown a potential antibacterial effect against the bacteria present in the oral cavity, especially against Gram-positive bacteria. This effect is mostly bacteriostatic. This study also found bacterial resistance toward TAM. Key words: Bacteria, oral cavity, tamoxifen, Gram-positive, Gram-negative
