Evaluation of biofilm formation activity of standard microorganism strains

Amaç: Biyofilm mikroorganizmaların meydana getirdikleri bir yapıdır. Biyofilm içerisindeki bakteriler, planktonik formları ile kıyaslandığında tıbbi ve endüstriyel açıdan çok daha önemli sorunlara neden olmaktadır. Bu bakımdan mikroorganizmaların biyofilm aktivitelerinin bilinmesi önemlidir. Bu çalışmada bazı mikroorganizma suşlarının biyofilm oluşturabilme yetenekleri gösterilerek bu konunun önemi vurgulanmaya çalışılmıştır.Yöntemler: Çalışmada 15 adet bakteri ve iki adet maya standart suşu kullanılmıştır. Standart suşların biyofilm üretim kapasitelerinin belirlenmesi amacıyla mikrotitre plak yöntemi kullanılmıştır. Biyofilm formasyonları negatif kontrol değeri baz alınarak 'biyofilm oluşturmayan =0, zayıf biyofilm = I, orta dereceli biyofilm = II ve güçlü biyofilm =III olarak değerlendirilmiştir.Bulgular: Yapılan çalışma sonrasında 17 adet standart suşun tamamında biyofilm oluşumu gözlenmiştir. Standart mikroorganizmalardan Pseudomonas aeruginosa, Staphylococcus aureus, Corynebacterium pseudotuberculosis ve Neisseria sicca güçlü biyofilm oluşturmuşlardır. Sonuç: Mikroorganizmaların oluşturdukları biyofilmlerin insan sağlığı açısından olumsuz sonuçlara yol açtığı bilinmektedir. Bu bakımdan biyofilm formasyonlarının anlaşılması ile ilgili yapılacak çalışmalar önemlidir. Çalışmamızda sunduğumuz standart mikroorganizmalara ait biyofilm formasyon verilerinin bu konuda çalışma yapacak araştırıcılara ve konuyla ilgili literatüre katkı sağlayacağını düşünmekteyiz.

Standart mikroorganizma suşlarının biyofilm formasyon aktivitelerinin değerlendirilmesi

Objective: Biofilm is a structure formed by a group of microorganisms. Bacteria in the biofilm lead to much more serious problems in medical and industrial terms when compared to their planktonic forms. In this sense, it is important to know about the biofilm activities of the microorganisms. The ability of certain microorganism strains to form biofilms was shown, and the importance of this subject was tried to be emphasized in this study.Methods: Fifteen bacteria and two yeast standard strains were used in the study. Microtiter plate method was used in order to determine the biofilm production capacities of standard strains. Biofilm formations were assessed as "nonadherent =0,weakly adherent = I, moderately adherent = II and strongly adherent =III." Results: Biofilm formation was observed in all of the 17 standard strains following the study carried out. Among standard microorganisms, Pseudomonas aeruginosa, Staphylococcus aureus, Corynebacterium pseudotuberculosis and Neisseria sicca created a strong biofilm.Conclusion: It is known that biofilms formed by microorganisms lead to negative consequences in human health. Therefore it's important to study on understanding biofilm formations. We believe that the biofilm formation data of the standard microorganisms we provide in our study will contribute to the researchers to conduct researches on this subject and the literature related to the subject.
