Abstract

The purpose of this study was to evaluate the pathogene of Aeromonas hydrophila genes (Aerolysin) as the cause of Lepidochelys olivacea death and to perform the antibiotic sensitivity test for antibiotic that often used in order to provide the best antibiotic treatment in the field case. The method used was the identification test using primary cultures on Tryptic Soy Agar (TSA) and Mac Conkey Agar (MCA) medium, then followed by Gram staining, oxidase, catalase, and biochemical tests. Then, aerolysin genes detection was performed by using Polymerase Chain Reaction (PCR) method, while oxytetracycline, chloramphenicol, streptomycin, and kanamycin were tested for their sensitivity. From five samples of dead Lepidochelys olivacea, bleeding on the liver and intestine were observed. The identification result of bacteria was found A. hydrophila, and identified the gene encoding aerolysin. The antibiotic sensitivity test showed a sensitive category of A. hydrophila with a sensitivity level were oxytetracycline, chloramphenicol, kanamycin, and streptomycin. The main cause of Lepidochelys olivacea death in Turtle Conservation and Education Centre, Serangan Island, Bali was A. hydrophila which contains aerolysin genes, in which oxytetracycline seems to be the most effective drug for the treatment. ABSTRAK Tujuan dari penelitian ini adalah membuktikan adanya gen patogen (Aerolysin) pada Aeromonas hydrophila sebagai penyebab kematian tukik penyu abu-abu serta mengetahui kepekaan obat antibiotic yang sering digunakan sehingga dapat memberikan terapi yang tepat pada kasus di lapangan. Metode penelitian yang digunakan adalah uji identifikasi menggunakan kultur primer pada media Tryptic Soy Agar (TSA) dan Mac Conkey Agar (MCA), dilanjutkan uji pewarnaan Gram, uji oksidase, uji katalase, dan uji biokimiawi. Setelah itu dilakukan deteksi gen aerolysin menggunakan metode Polymerase Chain Reaction (PCR), serta dilakukan uji sensitivitas antibiotik oxytetracycline, chloramphenicol, streptomycin, dan kanamycin. Dari lima sampel tukik abu-abu yang mati, secara patologi anatomi ditemukan adanya perdarahan pada hati dan usus. Hasil identifikasi bakteri ditemukan adanya A. hydrophila serta teridentifikasi adanya gen penyandi aerolysin. Pada uji sensitivitas antibiotik terhadap A. hydrophila yang ditemukan diketahui urutan sensitivitasnya adalah oxytetracycline, chloramphenicol, kanamycin, dan streptomycin. Penyebab utama kematian tukik penyu abu-abu di Turtle Conservation and Education Centre, Pulau Serangan, Bali adalah A. hydrophila yang mengandung gen aerolysin serta obat yang paling efektif adalah oxytetracycline.

Abstract

Water monitor lizards are consumed by humans for its meat. The demand this reptile consumption because the taste and belief of the people in healing disease. Based on habitat and food, they have the potential to transmit zoonosis and have a high possibility of being infested by parasites. One of the possible disease that could infect water monitor and transmitted to human is acanthocephaliasis, infection from Acanthocephalan. Which previous research found Acanthocephala on intestine of frog. This research aims to know and identify Acanthochepala worms that infect water monitor lizards. Based on the results, 40 samples were used and there are 2 positive samples with Acanthocephalan in the body cavity.

Abstract

This research was conducted to detect the presence of Pentastomida on Crab-eating Frog (Fejervarya cancrivora) in Surabaya and Sidoarjo areas. A total of 50 samples were taken in three different time and the identification was conducted in Laboratory of Parasitology, Universitas Airlangga by Semichen-Acetic Carmine staining method. Pentastomida that found in the body of Crab-eating Frog (Fejervarya cancrivora) was belong to Maxillopoda class which is included in Crustacea subphylum were matched by macroscopic and microscopic taxonomy and observation. The result of this research showed that there found Pentastomida on Crab-eating Frog collected Surabaya and Sidoarjo areas, East Java.
