“…Thus, it indicated that the balance between V. alginolyticus H1 and P. piscicida H2 was likely to be intimately associated with cuttlefish health. It has been generally accepted that V. alginolyticus isolates are the common causes of the diseases, and they can infect a wide variety of marine hosts, including fish [40] , crabs [41] , pearl oysters [4] and cuttlefish [6] . Meanwhile, Pseudoalteromonas isolates have been generally considered to be involved in predator-like interactions within the microbial loop, and to be used as a defense agent against pathogens in marine fauna [42] .…”

“…So the fish were injected with 100 µL of S. iniae bacterial suspension containing 3.66×10 8 CFU ml -1 by insulin syringe, intraperitonally [22] and were entered in 21 PVC tanks and monitored for next ten days. Cumulative mortality of each injected fish group was recorded at the end of next ten days period in each bacterial challenge test (40 th and 55 th days of trial). During the bacterial challenges oxygen was supply by aeration with an air pump and 50 percent of tanks water was exchanged daily [23] .…”

“…Bacterial infections are primarily the cause of the mass mortality that occasionally occur in marine fish hatcheries (Balachandran et al, 2013). Vibrio plays a vital role in marine culture ecosystem as they damage causing diseases and mortality to some aquaculture commodities (Ganesh et al, 2010).…”

Bacterial isolation was carried out on sea bass Lates calcarifer juvenile with black body syndrome (BBS) and isolates of Pseudomonas stutzeri L01, Vibrio harveyi, Bacillus cereus, Salinicoccus roseus, and Pseudomonas stutzeri L02 were obtained. Microscopic anatomical pathology of each bacterium needs to be done to determine its pathogenicity. This study aims to compare the degree of damage to sea bass juveniles' liver and kidney organs through histopathological observations due to bacterial infections that cause BBS. The degree of histopathological damage was determined by scoring histopathological changes in the tissue under a microscope with a magnification of 40×10 in five fields of view. The data obtained were analyzed using SPSS 24 software and further tested with Kruskal-Wallis and Post Hoc (Mann Whitney). The results showed that fish liver and kidney organs in all treatments experienced necrosis compared to the control treatment, but not significantly different between bacterial infection treatments. Histopathological observations of kidney and liver organs of sea bass juveniles infected with bacteria that cause BBS show necrosis damage that was classified as normal and mild. Keywords: bacteria, histopathology, Lates calcarifer ABSTRAK Isolasi bakteri telah dilakukan pada benih ikan kakap putih yang mengalami black body syndrome (BBS) dan diperoleh isolat bakteri Pseudomonas stutzeri L01, Vibrio harveyi, Bacillus cereus, Salinicoccus roseus, dan Pseudomonas stutzeri L02. Patologi anatomi mikroskopis dari masing-masing bakteri perlu dilakukan untuk mengevaluasi patogenitasnya. Penelitian ini bertujuan membandingkan tingkat kerusakan organ hati dan ginjal benih ikan kakap putih melalui pengamatan histopatologi akibat infeksi bakteri penyebab BBS. Derajat kerusakan histopatologi ditentukan dengan melakukan skoring perubahan histopatologi jaringan di bawah mikroskop dengan perbesaran 40×10 pada lima lapang pandang. Data dianalisis menggunakan software SPSS 24 dan diuji lanjut dengan Kruskal-Wallis dan Post Hoc (Mann Whitney). Hasil pengamatan menunjukkan bahwa organ hati dan ginjal ikan pada semua perlakuan infeksi mengalami nekrosis dibandingkan dengan perlakuan kontrol, tetapi tidak berbeda nyata antar perlakuan infeksi bakteri. Hasil pengamatan histopatologi organ ginjal dan hati benih ikan kakap putih yang diinfeksi dengan bakteri yang menyebabkan BBS menunjukkan kerusakan nekrosis yang tergolong pada derajat normal dan ringan.
