Abstract

Lactobacilli are member of normal vaginal flora. They maintain low pH of vaginal discharge by metabolising glycogen in vaginal epithelial cell and protects the vagina against the pathogenic microorganisms. However, the vaginal flora can be changed because of birth, taking antibiotics and contraceptive pills. Thus, whereas Lactobacilli population decreases, Gardnerella vaginalis and mixed anaerobic bacteria population increase and this situation causes an infection named Bacterial vaginosis. In this infection, the main diagnostic criteria are clue cells. The clue cell is a squamous epithelial cell which is covered by bacteria. First step of infection progress is adhesion of bacteria to epithelial cell through the adhesion molecules. The most important adhesion molecules of epithelium are cadherins, fibronectins, Toll like receptors and carbohydrates. In bacteria, pilis, lypopolysaccaharide and biofilm have primary importance. In this review, the adhesion molecules are discussed in detail and their roles in formation of clue cell are clarified.

Özet

İnsan vajinal florasında yaşayan laktobasiller epitel hücrelerin glikojenini kullanarak ortam pH'sını 4-4,5 gibi asidik bir değerde tutmakta ve vajinal florayı çeşitli mikroorganizmalara karşı korumaktadırlar. Fakat doğum, antibiyotik ve doğum kontrol haplarının kullanımı gibi çeşitli nedenlerle floranın dengesi bozulmakta ve laktobasillerin sayısı azalmaktadır. Bu durumda da ortama başta Gardnerella vaginalis olmak üzere çeşitli anaerobik bakteriler hakim olmakta ve bakteryel vajinozis dediğimiz enfeksiyon meydana gelmektedir. Bu enfeksiyonun en önemli tanı bulgusu da "clue cell" adını verdiğimiz üzeri bakterilerle kaplı skuamoz epitel hücrelerinin görülmesidir. En fek - siyon oluşumunun ilk basamağını ise adezyon molekülleri ile bakterilerin epitel hücreye yapışması oluşturmaktadır. Bu basamakta da çeşitli adezyon molekülleri görev almaktadır. Epitel hücre zarındaki adezyon moleküllerinden en önemlileri kaderinler, fibronektinler, Toll benzeri reseptörler ve karbonhidratlardır. Bakterilerde en önemli adezyon molekülleri ise pili, bakteri hücre duvarı yapısında bulunan lipopolisakkarit ve biyofilmdir. Bu derlemede adezyonda görev alan bu moleküllerin yapısına detaylı olarak değinilecek ve clue cell oluşum mekanizmasındaki rolleri açıklanacaktır.
