Abstract

ABSTRACT This study was aimed at determining potential of combination powder of garlic Allium sativum-shatterstone herb Phyllanthus niruri supplemented in feed against S. agalactiae infection in tilapia. Four concentrations of combination powder of A. sativum-P. Niruri; 20+5, 20+10, 20+15 and 20+20 ppt respectively were investigated for their ability to inhibit bacterial fish pathogen. Combination dose of 20+15 ppt produced the highest inhibitory zones in in vitro test. In vivo test consisted of three treatments with three replications, namely positive control (K+), negative control (K-) and the treatment of A. sativum-P. niruri suplemented in feed (BM).  The test perfomed on tilapia with weight of 10.33 ± 1.63 g and were reared at density of 10 ind/aquarium. The fish was fed for 14 days, then injected intraperitoneally with 0.1 mL S. agalactiae at concentration of 105 cfu/mL for positive control and BM groups. Survival, growth rate, feed response, hematological and water quality parameters were observed for 10 days. This study showed that the suplemented-feed-fish (BM) showed better growth rate, feed response, and survival (83.3%) than positive control (36.7%) at P<0.05. In addition, A. sativum-P. niruri suplemented in feed was also able to enhance the immune response by increasing phagocytic activity. Keywords: Streptococcus agalactiae, phytopharmacy, Allium sativum-Phyllanthus niruri, tilapia  ABSTRAK Penelitian ini bertujuan untuk menganalisis potensi campuran tepung bawang putih Allium sativum-meniran Phyllanthus niruri dalam pakan terhadap pencegahan infeksi bakteri S. agalactiae pada ikan nila.

Abstract

ABSTRACT The study was aimed to evaluate the efficacy of formalin-killed non-hemolytic Streptococcus agalactiae N14G and NK1 isolates whole-killed vaccine to prevent streptococcosis in tilapia. Ten fishes were reared in a tank 60x30x35 cm3 with an average body weight at 10.79±0.99 g. Fish was vaccinated through bath immersion at a concentration of 109 cfu/mL. Fish was subsequently challenged by intraperitonial injection of Streptococcus agalactiae 105 cfu/mL at 11 days post-vaccination. Parameters observed were survival, relative percent survival (RPS), total leukocyte, phagocytic activity, antibody titer, total erythrocyte, haemoglobin level, haematocrit level, dan water quality. Samplings were performed in day-0, 20, and 30 after vaccination. Both vaccines have shown higher survival (60%) and RPS (40%) when challenged with pathogenic Streptococcus N14G isolates than other treatments. Based on RPS percentage observed, those vaccine were still not sufficiently effective to combat S. agalactiae infection. Keywords: tilapia, bath immersion, Streptococcus agalactiae, whole-cell vaccine ABSTRAK Penelitian ini bertujuan untuk mengevaluasi efikasi vaksin formalin-killed cell Streptococcus agalactiae tipe isolat nonhemolitik N14G dan NK1 se utuh yang diberikan melalui perendaman dalam mencegah penyakit streptococcosis pada ikan nila. Ikan nila yang digunakan memiliki bobot 10,79±0,99 g, dipelihara sebanyak sepuluh ekor dalam akuarium ukuran 60x30x35 cm3. Ikan divaksinasi dengan metode perendaman dengan dosis 109 cfu/mL. Uji tantang dilakukan pada hari ke-11 pascavaksinasi dengan dosis 105 cfu/mL. Parameter yang diamati meliputi sintasan (SR), sintasan relatif/relative percent survival (RPS), total leukosit, aktivitas fagositik, titer antibodi, total eritrosit, kadar hemoglobin, kadar hematokrit, dan kualitas air. Pengamatan parameter dilakukan pada hari ke-0, ke-10, ke-20, dan ke-30. Hasil penelitian menunjukkan perlakuan kedua vaksin yang diinfeksi bakteri patogen isolat N14G memberikan nilai sintasan dan nilai RPS tertinggi dibanding perlakuan lainnya. Nilai sintasan dan RPS kedua perlakuan tersebut adalah 60% dan 40%. Nilai RPS yang cukup kecil menunjukkan vaksin yang diberikan masih kurang efektif untuk mencegah infeksi bakteri S. agalactiae. Kata kunci: ikan nila, perendaman, Streptococcus agalactiae, vaksin sel utuh

Abstract

ABSTRACT The aim of this study was to evaluate infectivity of Ichtyophthirius multifiliis which caused white spot disease maintained at low temperature without its host. Briefly, the trophont stage of parasites were subjected at control (28 °C) and lower temperature (9 °C) for 14 consecutive days of observation. The rate of survival, and excystment of descendants were examined descriptively at the last day of observation. Here, the infectivity of parasite then performed by means infecting the model fish Poecilia sphenops (black moly) with escaping theronts. The results revealed that the survival rate and excystment  rate of parasite were decreased as maintaining period increased. The final rate of survival, and excystment of parasite were 35% and 33,3% respectively. Additionally, the descendants came out with high abnormality which recognized by weak mobility and lower infectivity (50%) compared to the control (80%). Then, it is concluded that, maintaining I. multifiliis at low temperature without its host for 14 consecutive days will decreased the infectivity. Keywords: white spot, obligat parasite, excystment, infectivity  ABSTRAK Penelitian ini bertujuan untuk mengevaluasi infektivitas parasit Ichtyophthirius multifiliis penyebab penyakit bintik putih (white spot) yang dipelihara tanpa inang pada suhu rendah.

Selama masa pemeliharaan tersebut tingkat kelulusan hidup, dan tingkat eksismen parasit diukur dan dibandingkan secara deskriptif. Hari terakhir pemeliharaan dilakukan uji tantang pada ikan black moly Poecilia sphenops untuk menilai infektivitas parasit. Hasil penelitian memperlihatkan bahwa tingkat kelulusan hidup dan eksismen parasit semakin menurun dengan bertambahnya masa pemeliharaan. Akhir pengamatan  kelangsungan hidup, dan nilai eksismen tersebut berturut-turut adalah 35% dan 33%. Parasit yang disimpan pada suhu rendah selama 14 hari memperlihatkan infektivitas yang lebih rendah (50%) dibandingkan dengan perlakuan kontrol (80%). Kesimpulannya, penyimpanan parasit I. multifiliis pada suhu rendah selama 14 hari dapat menurunkan infektivitas parasit pada inang. Kata kunci: bintik putih, parasit obligat, eksismen, infektivitas

Abstract

ABSTRACT  Target production of catfish in aquaculture can be reached by suppressing the pathogenic bacterial infection. Previous works had shown that turmeric Curcuma longa has antibacterial activity. The objectives of this research were to determine the best method of extraction and to evaluate the efficacy of turmeric extract as feed additive to control Edwardsiella tarda disease in catfish culture. Briefly, the objective was achieved through in vitro assay based on inhibition ability of extraction method against E. tarda, while the following objective was obtained through in vivo assay based on their survival during challenge test either as preventive or curative measurement. A complete randomized design with three replications was used for each assay. Furthermore, challenge test was done by mean intraperitoneal injection at concentration 106 cfu/mL of E. tarda (LD50). The results showed that 15 minutes decoction method allowed the best inhibition with diameter 7.42 mm of clear zone and then curative measurement using turmeric extract could be the best application against E. tarda since it gave 86.67% of survival. Clinical signs such as swelling, hemoraghic, body ulcer, gastroentritis and gaseous captivity were observed on challenged fish. However, there were no significant different among treatments for specific growth, body weight, and absolute length parameters.  Keywords: Edwardsiella tarda, extraction, turmeric, catfish, inhibition zone  ABSTRAK Peningkatan produksi ikan lele dapat dicapai melalui pencegahan infeksi penyakit bakterial.
