Potential Distribution of the Amphibian Pathogen, Batrachochytrium dendrobatidis in the Eastern Black Sea Region of Turkey
Although Batrachochytrium dendrobatidis, pathogen for amphibians, has been reported in Anatolia, its geographical distribution, as well as its impact on the amphibians in Turkey, remained obscure. In this study, 62 adult individuals belonging to ten different species (Pelodytes caucasicus, Rana dalm...

Zusammenfassung: | Although Batrachochytrium
dendrobatidis, pathogen for amphibians, has been reported in Anatolia, its
geographical distribution, as well as its impact on the amphibians in Turkey,
remained obscure. In this study, 62 adult individuals belonging to ten
different species (Pelodytes caucasicus, Rana dalmatina, Rana
macrocnemis, Bufo bufo, Bufo verrucosissimus, Bufotes variabilis,
Hyla savignyi, Pelophylax ridibundus, Ommatotriton ophryticus,
and Mertensiella caucasicus) were collected from five wetland habitats
in Eastern Black Sea Region of Turkey. The prevalence and the intensity of B.
dendrobatidis infections in all the individuals were investigated by using
quantitative Real-time-PCR technique and the presence of B. dendrobatidis
infection was reported for the first time in 13 of the 62 individuals collected
from 10 amphibian species from Eastern Black Sea Region of Turkey. The
intensity of B. dendrobatidis infection ranged from 403.520 to 534.280
genomic equivalents (GE) was detected. The highest GE between
amphibian species were determined in P. caucasicus (534.280 GE)
in Uzungöl (Çaykara-Trabzon) and B. bufo (504.00 GE) in Lake
Karagöl (Şavşat-Artvin).
Amfibi patojeni Batrachochytrium
dendrobatidis Anadolu’da rapor edilmesine rağmen, hem coğrafik dağılımı hem
de Türkiye amfibileri üzerindeki etkisi hala belirsizdir. Bu çalışmada, Doğu
Karadeniz Bölgesindeki beş sulak alandan on farklı amfibi türlerine (Pelodytes caucasicus, Rana dalmatina, Rana macrocnemis, Bufo bufo,
Bufo verrucosissimus, Bufotes variabilis, Hyla savignyi Pelophylax
ridibundus, Ommatotriton ophryticus,
Mertensiella caucasicus) ait 62 ergin birey toplandı.
Kantitatif Real-time PCR tekniği ile tüm bireylerde B. dendrobatidis enfeksiyonlarının prevalansı ve yoğunluğu ile
araştırıldı ve Doğu Karadeniz Bölgesi’ndeki 10 amfibi türünden toplanan 62
bireyin 13’ ünde B. dendrobatidis
enfeksiyonu varlığı ilk kez rapor edildi. Enfeksiyon yoğunluğu 403,520-534,340
genomik eşdeğerler arasında değiştiği belirlendi. Amfibi türler arasında en
yüksek genomik eşdeğer Uzungöl’ deki P.
caucasicus (534,280) ve Karagöl'de B. bufo (504,00) saptandı. |
