Abstract

The definitive diagnosis of Trichomonas vaginalis, one of the common causes of sexually transmitted diseases in Turkey, relies both the microscopic examination and culture of frash varinal swabs. The aim of the study was to investigate the efficacies of Brain-Heart (BH) medium and modified tioglycolate medium (NaT) and without serum, for the culture of T. vaginalis in vitro, in comparison to TYM (tripticase-yeast extract-maltose) medium. Both media were prepared according to their original formulas and inactivated serum was then added to the half of the test tubes. Trichomonas vaginalis trophozoites were inoculated in an amount of 1x105 in all tubes, and their viabilities and growth rates were examined everyday for 9 days. The growth rates of all study groups were compared with TYM medium. The highest rate of growth (35x105) was found in serum-free BH medium at the end of 72 hours. The number of trophozoites in serum-free BH and modified NaT media was found to be equivalent to that in TYM medium on the following days. In addition, T. vaginalis trophozoites were detected only in serum-free BH and NaT media on the 8th day. Serum-free culture media are easy-to-prepare and have lower risk of contamination. The findings indicate that they could be useful in the culture of T. vaginalis for both routine diagnosis and field studies.

Özet

Ülkemizde cinsel ilişki ile bulaşan hastalık etkenleri arasında sık görülen Trichomonas vaginalis'in tanısı, taze preparatların mikroskop altında incelenmesi ve alınan materyalin besiyeri ortamına ekilerek değerlendirilmesi ile konulmaktadır. Parazitin üretilmesi için serumun gerekli olup olmadığını saptamak amacı ile bu çalışma yapılmıştır. Trichomonas vaginalis'in in vitro üretilmesinde Beyin-Kalp (BH) ve modifiye Tiyoglikolat (NaT) besiyerleri serum ile ve serumsuz olarak hazırlanmış, üretme kapasiteleri ve tanısal etkinlikleri TYM (Trypticase-yeast extact-maltose) besiyeri ile karşılaştırmıştır. Besiyerlerine 1X10 5 canlı T. vaginalis trofozoitleri ekilmiş, 24 saat ara ile dokuz gün boyunca üreme fazları ve canlılıkları değerlendirilmiştir. Trofozoitlerin üreme durumu incelendiğinde, en fazla üremenin 72. saatte serum içermeyen BH besiyerinde olduğu (35x105 tane/ml) görülmüştür. Sonraki günlerde serum içermeyen besiyerlerindeki üremenin TYM besiyeri ile eşdeğer düzeyde olduğu, sekizinci günde ise sadece serum içermeyen besiyerlerinde trofozoitlerin canlı kaldığı saptanmıştır. Serum içermeyen besiyerleri laboratuvarlarda rahatlıkla bulunan malzemeler kullanılarak kolay hazırlanabilmekte, ayrıca serum ilave edilirken oluşabilecek kontaminasyon riski en aza indirilmektedir. Bu bulgular ışığında, serum içermeyen besiyerlerinin T. vaginalis kültüründe ve pasajların sürekliliğinde rahatlıkla kullanılabileceği, hem laboratuvarlarda hem alan çalışmalarında avantaj sağlayabileceği kanısına varılmıştır.
