Abstract

The functions of epithelial cells are more than a physical selective barrier for protection from mucosal pathogens. The epithelial response regulated by host-microorganism interaction may change due to histological and physiological differences between sterile and nonsterile sites. In this study we examined the presence of a difference between bactericidal capacities of urinary and oral epithelial cells against different strains of Escherichia coli. Oral epithelial cells were collected from unstimulated saliva and uroepithelial cells were collected from urine of eight healthy volunteers. E.coli K12 and 075 strains and epithelial cells were prepared for the experiment, added to microplates and incubated for one hour. The growth of bacteria was detected by the quantitative colony counting method. Antibacterial effects of the oral and urinary epithelial cells against E.coli K12 and 075 strains were 49.8%, 34.7%, 45.7% and 29.2%, respectively. As a result, it was detected that the antibacterial activity of oral epithelial cells to E.coli K12 and 075 were higher than urinary epithelial cells.

Özet

Epitel hücresi mukozal patojenden korunmada oldukça seçici bir bariyer rolü üstlenmektedir ve fiziksel bariyer olmaktan çok daha fazla etkiye sahiptir. Konak-mikroorganizma ilişkisi ile düzenlenen epitel yanıtı; konağın floralı ve florasız bölgelerinin histolojik ve fizyolojik farklılıkları nedeniyle değişebilmektedir. Çalışmamızda üriner sistem ve ağız epitel hücrelerinin Escherichia coli suşlarına karşı bakterisidal etki gücünün farklı olup olmadığı araştırılmıştır. Ağız epitel hücreleri sekiz sağlıklı gönüllünün uyarılmamış tükrüğünden, üriner sistem epitel hücreleri ise aynı gönüllülerin idrarlarından toplanmıştır. E.coli K12 ve 075 suşları ve epitel hücreleri deney için hazırlandıktan sonra 96 çukurlu mikropleytte bir saat karşılaştırılmıştır. Bakteri üremesi kantitatif koloni sayma yöntemi ile değerlendirilmiştir. Ağız epitel hücrelerinin E.coli K12'ye karşı bakterisidal etkisi %49.8, E.coli O75'e karşı %45.7 olarak bulunmuştur. İdrar epitel hücrelerinin antibakteriyel etki gücü E.coli K12'ye karşı %34.7, E.coli O75'e karşı %29.2 olarak saptanmıştır. Sonuç olarak, ağız epitel hücrelerinin E.coli K12 ve O75'e karşı antibakteriyel etkinliğinin idrar epitel hücrelerinden yüksek olduğu belirlenmiştir.
