Türkiye’de Kültürü Yapılan Sinarit Balıklarında (Dentex dentex) İlk Vibrio harveyi Enfeksiyonu Bildirimi

Abstract

In the present work, Vibrio harveyi was consistently isolated from diseased common dentex (Dentex dentex) cultured in Turkey. The outbreak occurred in July (2013), following the transportation of common dentex juveniles from hatchery to offshore floating cages. Five moribund cultured common dentex individuals, about 20-25 g in weight, were selected from the said floating cages and samples were taken from internal organs including liver, spleen, kidney and eye tissue. A total of eight pure cultures were obtained and identified through basic biochemical characterisation as well as 16S rRNA gene sequencing. To our knowledge, this is the first report of Vibrio harveyi infection in cultured common dentex in Turkey.

Bir Deniz Akvaryumunda Salpa Balıklarında (Sarpa salpa) Vibrio harveyi Enfeksiyonu Olgusu: ilk rapor

“…Our findings such as hemorrhaging, scale loss and skin depigmentation in addition to haemorrhages in various parts of the body including in the intestines but also hyperemia in visceral organs are typical findings of V. harveyi infection in fish. Similar clinical signs were reported in various outbreaks in other sparids such as common dentex (Company et al, 1999;Haldar et al, 2010;Turgay and Karataş, 2016), gilthead sea bream (Pujalte et al, 2003) and nonsparids (Austin and Zhang, 2006). As a matter worth mentioning, we did not observe any eye lesions or corneal opacities that have been reported as a common clinical finding in several disease outbreaks of sparids.…”

“…Vibrio harveyi is a well-known bacterium causing disease with high mortality in marine aquaculture and outbreaks have been reported in various fish species including common dentex (Dentex dentex) (Company et al, 1999;Pujalte et al, 2003;Turgay and Karataş, 2016), gilthead sea bream (Sparus aurata) (Balebona et al, 1998;Haldar et al, 2010;Pujalte et al, 2003) and European sea bass (Dicentrarchus labrax) (Pujalte et al, 2003). Moreover, vibriosis caused by V. harveyi has also been reported in farmed sole (Solea senegalensis) (Zorrilla et al, 2003), cultured wedge sole (Dicologoglossa cuneata) (López et al, 2009), cultured brown spotted grouper (Epinephelus tauvina), silvery black porgy (Acanthopagrus cuvieri) (Saeed, 1995) and cage-reared grouper (Epinephelus awoara) (Qin et al, 2006).…”

Effect of Dietary Canarium indicum L. on the Growth, Health, and Resistance of Asian Seabass Challenged with Vibrio alginolyticus

“…The treatments challenged with V. alginolyticus showed clinical signs such as anorexia, lesions operculum, dropsy abdomen, dropsy internal organ (Figure 2), and death. These clinical signs revealed that vibriosis in fish is characterized by behavioral changes such as anorexia (Ransangan and Mustafa, 2009), lesions operculum (Turgay and Karataş, 2016), dropsy abdomen (Canak and Akayli, 2018), and dropsy internal organ (Silvaraj et al, 2020).…”
