Abstract

ABSTRACT    Streptococcus agalactiae is a major bacterial streptococcosis disease that infects tilapia. This study aimed to analyze a specific and nonspecific immune system in fry tilapia that has been given with S. agalactiae vaccine from N3M and N4M strain and examine the protective immunity against S. agalactiae N3M, N4M, N17O, NK1,  and N14G strains infection. Fry tilapia used in this study has the weight of 7.086±0.948 g and length of 7.443±0.353 cm. The S. agalactiae strains that used were N3M, N4M, N17O, NK1,and N14G. Fry tilapia was vaccinated through intraperitoneal injection method with 0.1 mL per fish of N3M and N4M vaccines. Fish reared in aquarium sizing of 60×30×50 cm3 with a density of 10 fishes aquarium-1. Two weeks after vaccination, fry tilapia was tested with 0.1 mL fish-1 of each N3M, N4M, N17O, NK1, and N14G strains through intraperitoneal injection method. Antibody level measured with indirect enzym-linked immunosorbent assay (ELISA) method. The result of antibody level in vaccinated fish after vaccination of N3M, N4M vaccine, N3M and N4M control were 0.767; 0.743; 0.587; and 0.544, respectively. Relative percent survival in N3M vaccinated fish after challenged with N3M and N4M was 87.50% dan 64.70%, respectively, otherwise in N4M vaccinated fish was 62.50% dan 76.47%, respectively. N3M and N4M vaccine strain have better protection as only if it tested with similar bacteria strain. Keywords: formalin-killed cell, tilapia, protection, Streptococcus agalactiae, strains  ABSTRAK Streptococcus agalactiae merupakan bakteri utama penyakit streptococcosis yang menginfeksi ikan nila.

Abstract

ABSTRACTLysozymes play an important role in the first line of defense in fish and potentially used as an immunity status biomarker and immune responses evaluation in fish, which often found in two types, i.e. chicken-type and goose-type (c- and g-type, respectively). To recent, the information related to the sequences and the expression analysis of the c- and g-type lysozyme genes in African catfish is still limited. In the present study, we report a partial cloning and mRNA expression analysis of c-type and g-type lysozymes in African catfish Clarias gariepinus. We have successfully cloned and partially identify the c-type, and g-type lysozyme genes of C. gariepinus, which consist of 594 and 560 of coding sequences, respectively. Catalytic and other conserved residues were identified by multiple sequences alignment and they showed high similarity with other teleost fish species. mRNA levels of the genes were analyzed by using qPCR method and their expressions in the spleen, liver, and head kidney were rapidly modulated after Aeromonas hydrophila injection, with different patterns were observed in each organ. These results confirmed that c- and g-type lysozymes played an important role in non-specific immunity against A. hydrophila infection. This study provided valuable information that can be used to understand the African catfish immune systems for better disease and stress management in C. gariepinus culture.Keywords: lysozymes, gene identification, gene expression, bacterial infection, African catfish ABSTRAKLisozim berperan dalam sistem pertahanan dini pada ikan dan sangat potensial digunakan sebagai marka status imunitas dalam evaluasi respons imun. Lisozim umum ditemukan dalam dua tipe pada ikan: tipe-ayam (tipe-c) dan tipe-angsa (tipe-g). Informasi terkait sekuens gen dan ekspresi gen kedua tipe lisozim pada ikan lele dumbo sangat terbatas. Pada penelitian ini, kami melaporkan kloning gen secara parsial, dan analisis ekspresi gen dari kedua tipe lisozim pada ikan lele dumbo C. gariepinus. Sekuens parsial gen lisozim tipe-c dan tipe-g yang berhasil diidentifikasi adalah sepanjang 594 dan 560 pasang basa. Situs katalitik dan residu khas memiliki tingkat kesamaan yang tinggi dengan spesies ikan yang lain. Analisis mRNA dilakukan dengan metode quantitative PCR (qPCR). Ekspresi kedua gen di jaringan ginjal depan, limpa, dan hati dengan cepat terinduksi pasca infeksi bakteri A. hydrophila dengan pola yang berbeda. Hasil ini menunjukkan bahwa lisozim tipe-c dan tipe-g memiliki peran yang sangat penting dalam sistem imun ikan lele dumbo terhadap infeksi A. hydrophila. Penelitian ini menghasilkan informasi penting yang dapat digunakan untuk mempelajari sistem imun ikan lele dumbo dan sebagai acuan dalam penanganan dan manajemen penyakit pada budidaya ikan lele dumbo.Kata kunci: lisozim, identifikasi gen, ekspresi gen, infeksi bakteri, ikan lele dumbo

Abstract

ABSTRACT The study aimed to analyze the efficacy of Aeromonas hydrophila formalin-killed cells (FKC) and lipopolysaccharides (LPS) vaccines in maternal immunity of tilapia broodstock and the resistance of the offsprings. This study consisted of two consecutive studies. Firstly, the broodstocks were vaccinated with PBS (non-vaccinated), FKC, LPS, and combinations of  FKC and LPS. Secondly, the offsprings from both the vaccinated and non‒vaccinated broodstock were vaccinated with the same vaccine for broodstock by immersion method. After vaccination, the offsprings were challenged with pathogenic A. hydrophila. Antibody level and lysozyme were measured in the broodstock, egg, and offsprings. In the first experiment, the result showed that vaccinated broodstock and their offsprings had delivered a significant antibody level and lysozyme activity compared with the control.  The highest relative percent survival (RPS) of offspring resulted from the combination of  FKC and LPS vaccinated broodstock at 5, 10, and 15 days post-hatching at 85.00%, 75.23%, and 67.56%, respectively.  The second experiment showed vaccinated offsprings produced from vaccinated broodstock had a higher RPS than the RPS of vaccinated offsprings which produced from non-vaccinated broodstock. In conclusion, vaccination that using a combination of FKC and LPS vaccine in broodstock potentially improved the maternal immunity and protect their offspring from A. hydrophila infection. Keywords: Aeromonas hydrophila, antibody, maternal immunity, tilapia, vaccination ABSTRAK Penelitian ini bertujuan menganalisis efikasi vaksin formalin-killed cells (FKC) dan lipopolisakarida (LPS) Aeromonas hydrophila pada imunitas maternal induk ikan nila dan ketahanan benih yang dihasilkan. Dalam penelitian ini, terdapat dua penelitian. Pertama, induk ikan nila divaksin dengan PBS (non-vaksinasi), vaksin FKC, LPS, dan kombinasi vaksin FKC dan LPS. Benih selanjutnya diuji ditantang dengan menggunakan  patogen A. hydrophila pada 5, 10, dan 15 hari pasca menetas. Kedua, benih yang dihasilkan oleh induk yang telah divaksinasi dan induk yang tidak divaksinasi tersebut divaksin dengan vaksin yang sama seperti pada induk dengan metode imersi. Setelah vaksinasi, keturunan diuji tantang dengan patogen A. hydrophila. Tingkat antibodi dan lisozim diukur pada induk, telur, dan benih. Pada percobaan pertama, hasilnya menunjukkan bahwa induk yang divaksinasi dan benih menunjukkan tingkat antibodi dan aktivitas lisozim yang signifikan dibandingkan dengan kontrol. Persentase kelangsungan hidup relatif (RPS) tertinggi benih yang dihasilkan dari induk yang divaksinasi FKC dan LPS masing-masing pada 5,10, dan 15 hari pascatetas pada 85,00%; 75,23%; dan 67,56%. Percobaan kedua menunjukkan bahwa benih yang divaksinasi dari induk yang divaksin menunjukkan RPS yang lebih baik daripada benih yang divaksinasi dari induk yang tidak divaksin. Vaksinasi menggunakan kombinasi FKC dan LPS pada induk berpotensi meningkatkan kekebalan induk dan melindungi benih dari infeksi A. hydrophila. Kata kunci: Aeromonas hydrophila, antibodi, imunitas induk, nila, vaksinasi

Abstract

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.

Abstract

Vibrio parahaemolyticus is a pathogenic bacterium that indusces mortality is pacific white shrimp. This study aimed to analyze the distribution of V. parahaeomyticus in shrimp through immersion and evaluate, polymerase chain reaction, histopathology, and immune response. The study employed two treatments with four replicates each. Shrimp were infected through immersion with V. parahaemolyticus at a concentration of 107 CFU/mL for 30 minutes, followed by transferring the shrimp to a rearing container. Gill, hepatopancreas, gut, and hemolymph samples were collected at 6, 12, and 24 hours post-infection. Infected shrimp exhibited clinical symptoms such as a pale body and hepatopancreas, along with empty gut. Shrimp mortality reached 97.08%, while no mortality occurred in the control grouph. The abundance of V. parahaemolyticus in organs exceeded 105 CFU/mL. Histopathological examination revealed mild, moderate, and severe damage. PCR confirmation tests at 12 and 24 hours yielded positive results, with a DNA band at 230 bp. Immune responses, including total hemocytes, phagocytic activity, phenoloxidase, and respiratory burst, demonstrated significantly different results (P<0.05). It was concluded that the distribution of V. parahaemolyticus in the shrimp body, specifically in the gills, hepatopancreas, and gut, exceed 105 CFU/mL, as confirmed by a 230 bp DNA band in the PCR test. Tissue damage, manifested as lesions and necrosis, occurred in the gills, hepatopancreas, and gut. Additionally, the imun response of Vibrio-infected shrimp was found to be lower than that of uninfected shrimp (negative control). Keywords: distribution, immersion, Litopenaeus vannamei, Vibrio parahaemolyticus ABSTRAK Vibrio parahaemolyticus adalah bakteri patogen yang menyebabkan kematian pada udang vaname. Penelitian ini bertujuan menganalisis distribusi V. parahaemolyticus pada udang melalui perendaman serta kerusakan yang ditimbulkan melalui pengamatan gejala klinis, angka lempeng total bakteri, polymerase chain reaction, histopatologi dan respons imun. Penelitian menggunakan dua perlakuan dan empat ulangan. Udang diinfeksi melalui perendaman menggunakan V. parahaemolyticus 107 CFU/mL selama 30 menit, kemudian udang dipindah pada wadah pemeliharaan. Pengambilan organ insang, hepatopankreas, usus dan hemolim dilakukan pada jam ke-6, 12, dan 24 pascainfeksi. Udang terinfeksi memiliki gejala klinis seperti tubuh dan hepatopankreas pucat, usus kosong. Mortalitas udang mencapai 97.08% dan tidak ada kematian pada udang kontrol. Kelimpahan V. parahaemolyticus pada organ lebih dari 105 CFU/mL. Pengamatan histopatologi menunjukkan kerusakan ringan, sedang, hingga parah. Uji konfirmasi PCR jam ke-12 dan ke-24 menunjukkan hasil positif pada 230 bp. Respons imun seperti total hemosit, aktivitas fagositik, phenoloxidase, respiratory burst menujukkan hasil yang berbeda nyata (P<0.05). Disimpulkan bahwa distribusi V. parahaemolyticus di dalam tubuh udang pada terdapat pada insang, hepatopankreas dan usus lebih dari 105 CFU/mL dan terkonfirmasi uji PCR pada pita DNA 230 bp. Kerusakan jaringan seperti lesi dan nekrosis terjadi pada insang, hepatopankreas, dan usus. Respons imun udang yang terinfeksi Vibrio lebih rendah dibandingkan udang yang tidak terinfeksi (kontrol negatif). Kata kunci: distribusi, Litopenaeus vannamei, perendaman, Vibrio parahaemolyticus
