Effects of albinism on Pseudomonas putida infection on convict cichlid (Cichlasoma nigrofasciatum)

Abstract

In the present study, naturally infected albino convict cichlids (Cichlasoma nigrofasciatum) were examined bacteriologically. The result of the examination Puseudomonas putida was isolated from the fish. After this result, comparing the difference of this infection in normal and albino fish was aimed. So, the challenge test trial system for this purpose was settled. Normal and albino fish were infected with stocked bacteria, and the results were observed. At the end of the experiment, all albino fish were observed to have died due to infection. Whereas deaths were not observed in the normal fish. As a result, albino fish (Cichlasoma nigrofasciatum) were found to be more sensitive to Puseudomonas putida infection than normal fish.Öz: Sunulan bu çalışmada doğal olarak enfekte olmuş çiklit (Cichlasoma nigrofasciatum) balıkları bakteriyolojik olarak incelenmiştir. Bakteriyolojik muayene sonrası balıkardan Puseudomonas putida bakterisi izole edilmiştir. Bu sonuçlar sonrası normal ve albino çiklit balıklarının bu bakteriye karşı hassasiyetinin karşılaştırılması amaçlanmıştır. Bu yüzden, bir deneme düzeneği hazırlanmıştır. Normal ve albino balıklar bu bakteri ile enfekte edilmiş ve sonuçlat takip edilmiştir. Deneme sonucunda bütün albino balıkların öldüğü, normal balıklarda ise ölüm olmadığı gözlemlenmiştir. Sonuç olarak albino balıkların (Cichlasoma nigrofasciatum) normal balıklara göre Puseudomonas putida enfeksiyonuna daha hassas olduğu ortaya konulmuştur.

Antimicrobial activity oftrans-cinnamic acid and commonly used antibiotics against important fish pathogens and nonpathogenic isolates

“…Pseudomonas putida was previously isolated from diseased Convict Cichlid (Kayış et al . ), trout (Altinok et al . ), Atlantic salmon and yellowtail (Kusuda and Toyoshima ).…”

First Isolation of Acinetobacter sp. from Golden grey mullet (Liza aurata) in Turkey

“…Bacterial fish diseases are one of the major problems in aquaculture and can lead to severe economic losses in many countries. Sustainability and success in aquaculture depend on prevention of fish diseases and effective fish health management (Toranzo et al, 2005;Kayış et al, 2017;Ture & Kutlu, 2018;Balta & Dengiz Balta, 2016).…”
