Patella sp. (Gastropoda: Mollusca) mukus salgısına denizel bakterilerin yerleşimi

Tutunma ve kayma hareketleri gösteren Patella türlerinin oluşturduğu mukus salgısı mikroorganizmalar için bir yapışma ortamıdır. Türlere göre mukus salgısının bakterilerin çoğalma potansiyellerine etkisinin araştırılması amaçlanmış, deniz suyundan izole edilen Vibrio fluvialis ve V. furnissii türleri Patella caerulea ve P. rustica mukusuna aşılanmıştır. Yapışma yoğunlukları karşılaştırmalı olarak kristal viyole ile boyanmış lamlarda ışık mikroskobu düzeyinde belirlenmiştir. Vibrio türlerinin mukus tercihleri Patella türlerine göre farklılık göstermiştir. Bu çalışma bulguları, Patella sp. mukus tabakasının kaya üzerinde denizel bakterilerin yerleşimi açısından önemini ve bu bakterilerin diğer organizmalar için uyarıcı etki oluşturabileceğini düşündürmektedir.

Settlement of marine bacteria on Patella sp. (Gastropoda: Mollusca) mucus

The mucus which is used during locomotion of Patella species is a habitat for microorganism adhesion. In order to determine the increase capability of bacteria on mucus of different Patella species, Vibrio fluvialis, V. furnissii, isolated from seawater, were inoculated to Patella caerulea and P. rustica mucus. Adhesion densities of the bacteria on Patella sp. mucus were examined comparatively on crystal violet stained slides by light microscopy. Mucus preference of the Vibrio species differed according to the Patella sp. The results showed that mucous film on a rock, produced by a Patella sp., seems important for marine bacteria settlement which is directed to a presumption of mucus being a stimulant for succession of other organisms.
