Abstract

Objective: In the study, it is aimed to determine the prevalence of Acanthamoeba and other free-living amoeba (FLA) species in the swab samples obtained from conjunctiva and lower eye lid. Methods: For this purpose, swab samples from the 500 patients'eye lid and conjunctiva were obtained who admitted to Cumhuriyet University, Research and Application Hospital, Department of Ophthalmology with variety of reasons. Swab samples were carried out using sterile cotton swab in steril tubes. The swab samples were inoculated onto non-nutrient agar (NNA). Live Escherichia coli was used as food source for the growth of the FLA. The NNA plates were incubated at 300C and examined daily using ligth microscope for two weeks. For morphotyping of the trophozoites and cysts of the FLA were used taxonomic keys.Results: Two of the 500 swab samples (0.4%) were positive for FLA. One of them (0.2%) were identified as Acanthamoeba spp. and other was identified as Hartmannella spp. However, these patients did not reveal any complaints yet.Conclusion: FLA both themselves and bacteria carrying in their body as reservoirs are potantial pathogen. The rapid spread of Acanthamoeba keratitis in recent years reveal that these microorganisims are in contact with the eyes.

Özet

Amaç: Çalışmada, çeşitli yakınmaları nedeniyle Göz Hastalıkları polikliniğine başvuran hastaların alt göz kapakları ve konjunktivadan alınan sürüntü örneklerinde Acanthamoeba ve diğer serbest yaşayan amip türlerinin prevalansının belirlenmesi amaçlanmıştır. Yöntemler: Bu amaçla, Cumhuriyet Üniversitesi Sağlık Hizmetleri Uygulama ve Araştırma Hastanesi Göz Hastalıkları Anabilim Dalı polikliniğine çeşitli nedenlerle başvuran 500 hastadan elde edilen alt göz kapağı ve konjunktiva sürüntü örnekleri incelenmiştir. Steril eküvyonlar kullanılarak elde edilen hasta örnekleri, içinde serum fizyolojik bulunan ve steril, ağzı kapaklı tüplerde laboratuvara taşınmıştır. Daha sonra oda sıcaklığında bir gün bekletilen örnekler, üzerine Escherichia coli ekilmiş Besleyici Değeri Olmayan Agar içeren plaklara inoküle edilerek 300C'de inkübe edilmiştir. Üreme saptanan iki plaktaki amipler morfotiplendirme kriterlerine göre tanımlanmıştır.Bulgular: Çalışmada, 500 kişiden alınan sürüntü örneğinin birinde Acanthamoeba spp. (%0,2), birinde ise Hartmannella spp. (%0,2) üremiştir. Ancak bu hastalarda belirgin bir yakınma saptanmamıştır. Sonuç: Serbest yaşayan amipler hem kendileri hem de içlerinde taşıdıkları bakteri ve virüsler nedeniyle potansiyel patojendirler. Son yıllarda Acanthamoeba keratitinin hızla yayılması bu canlıların gözle temasta olduğunu ortaya çıkarmaktadır
