Abstract

This study was carried out for the investigation of the mortalities observed in Atlantic bonito (Sarda sarda) reared in a marine aquarium. Bacteriological and histopathological methods were used for the diagnosis and antibiogram susceptibility tests were made for the control of the disease. Ulcerative skin lesions over the body and head and hemorrhages at the fin bases were observed in the external examination of the fish. The hemorrhages over the visceral organs such as the liver and the gastrointestinal tract and besides liquefactive necrosis of the kidney were observed in the internal examination of the fish samples. Bacterial inoculations were made from the liver, spleen and kidney and also from the ulcerative regions over the body surface. Depending on the morphologic, physiologic and biochemical properties, bacterial isolates recovered from the fish samples were identified as Pseudomonas stutzeri and Acinetobacter sp. It was also determined that these isolates are sensitive to oxytetracycline and enrofloxacine. In the histopathological examination of the fish tissues, necrosis in the ulcerative skin lesions proceeding through the muscles, degeneration in the liver cells and kidney tubules, necrotic focci in the kidney and spleen, hemosiderin accumulation in the spleen and hemorrhages and necrosis in the gill filaments were observed. In conclusion, the results of this study showed that the fish reared in the marine aquaria are very sensitive to the mixed infections due to the stress developed after transportation. 

Özet

Bu çalışma, deniz akvaryumunda tutulan palamut balıklarında (Sarda sarda) meydana gelen ölümlerin nedenini araş- tırmak amacıyla yürütülmüştür. Teşhis için bakteriyolojik, parazitolojik ve histopatolojik yöntemler kullanılırken hastalığın tedavisinde kullanılacak olan etkili antibakteriyeli belirlemek için antibiyogram testi yapılmıştır. Bu balıklarda dış bakıda vücut yüzeyinde ve baş bölgesinde ülseratif deri lezyonları, yüzgeç diplerinde hemoraji, iç bakıda ise karaciğer ve sindirim kanalı gibi viseral organlarda hemoraji yanı sıra böbrek dokusunda erimeler tespit edilmiştir. Ticari bir akvaryum işletmesinden temin edilen palamut balıklarının karaciğer, dalak ve böbrek gibi iç organlarının yanı sıra vücut yüzeyindeki ülserli bölgelerinden bakteriyolojik ekimler yapılmış, inkübasyon sonrasında elde edilen izolatların morfolojik, fizyolojik ve biyokimyasal özellikleri incelendiğinde izole edilen bakterilerin Pseudomonas stutzeri ve Acinetobacter sp. olduğu tespit edilmiştir. Bu bakterilerin aynı zamanda oksitetrasiklin ve enrofloksasine karşı duyarlı olduğu tespit edilmiştir. Balık dokularının histopatolojik incelenmesi sonucunda kas dokusuna kadar ilerlemiş ülseratif deri lezyonlarında nekroz, karaciğer hücrelerinde ve böbrek tübüllerinde dejenerasyon, böbrek ve dalakta nekrotik alanlar, dalakta hemosiderin birikmesi ve solungaç filamentlerinde hemoraji ve nekroz tespit edilmiştir. Sonuç olarak; bu çalışmadaki veriler göstermiştir ki özellikle taşımaya bağlı olarak gelişen stres sonucu deniz akvaryumlarında tutulan balıklar karma bakteriyel enfeksiyonlara karşı oldukça duyarlıdır
