Brown Band Disease

ABSTRACT We detected and characterized two distinct scuticociliate ciliates inside Acropora corals in the South China Sea. One, voraciously foraging on Symbiodinium, resembled the brown band disease of ciliates. The other, which is closely related to Paranophrys magna, grazed on detritus instead of Symbiodinium. These two ciliates may serve contrasting functions (competitor versus “cleaner”) in the coral-ciliate-Symbiodinium triangular relationship.

ABSTRACT A ciliate associated with the coral disease brown band (BrB) was identified as a new species belonging to the class Oligohymenophorea, subclass Scuticociliatia. The ciliates were characterized by the presence of large numbers of intracellular dinoflagellates and displayed an elongated, tube-shaped body structure. They had uniform ciliature, except for three distinct cilia in the caudal region, and were typically 200 to 400 μm in length and 20 to 50 μm in width.

Penyakit karang sekarang ini sudah menjadi perhatian utama para peneliti karang. Banyak kasus dilaporkan penyakit karang menjadi penyumbang terbesar kematian karang di sebuah perairan. Penelitian ini bertujuan untuk mengetahui prevalensi dan kelimpahan penyakit karang di Perairan Desa Buton, Kabupaten Morowali, Sulawesi Tengah. Metode pengambilan data prevalensi dan kelimpahan penyakit karang menggunkan belt transect (transek sabuk) dengan luas 180m2 yang ditarik sejajar garis pantai pada 3 (tiga) titik stasiun. Hasil penelitian menunjukan ditemukan sebanyak 5 (lima) jenis penyakit karang (White Band Disease, Brown Band Disease, Ulcerative White Spot, Bleaching, dan Black Band Disease dan 3 (tiga) jenis gangguan kesehatan karang (Fish bites, Crown-of-Thorn-Starfish (COTS), dan Tube formers). Secara umum total prevalensi penyakit karang di lokasi penelitian sebesar 78,7% (52,3% penyakit karang dan 26,4% berupa gangguan kesehatan karang) dengan kasus tertinggi terdapat di stasiun 1 (satu). lebih lanjut kelimpahan rata-rata penyakit karang sebesar 0,65 koloni/m2. Kelimpahan penyakit karang tertinggi ditemukan pada stasiun I yaitu sebesar 0,32 koloni/m2.Kata Kunci: Penyakit Karang, Prevalensi, Kelimpahan, Perairan Desa Buton

Brown Band Disease

The coral reefs’ condition in most regions in Indonesia has been declining due to coral diseases, such as Brown Band Disease (BrBD). A treatment for BrBD involves the use of biological control agents that have antagonistic properties against disease-causing agents. This study aimed to isolate bacteria from healthy hard coral, those associated with BrBD, and those that had bioactivities against BrBD. Sampling and identification of corals and BrBD were carried out in March 2015 at the Marine National Park of Karimunjawa. Bacteria from healthy and infected corals were isolated and purified. The isolates were subjected to antipathogenic assay using overlay and agar diffusion methods. Finally, molecular identification of active bacteria was carried out using the 16S rRNA gene amplification. As many as 57 bacterial isolates were obtained from healthy coral, as well as four bacterial isolates from coral with BrBD symptoms. A total of 15 bacterial isolates (26%) showed antipathogenic activity against BrBD-associated bacteria. Three isolates with the strongest antipathogenic activities, i.e., GAMSH 3, KASH 6, and TAPSH 1 were identified by 16S rRNA gene sequences. The results showed that they were aligned to Virgibacillus marismortui (97%), Oceanobacillus iheyensis (97%), and Bacillus cereus (96%), respectively.
