Abstract

M. tuberculosis is a bacterium that has many evasion mechanisms against the immune system, one of them is the formation of granulomas which is beneficial for the bacteria’s survival. The granuloma structure is useful for limiting the spread of M. tuberculosis and localizing infection, also considered as part of M. tuberculosis life cycle that successful fighting the body's immune system. This study aims to look at the formation of an in vitro tuberculous granuloma model. This study used the True Experiment type which began with blood sampling, PBMC isolation, macrophage isolation, MOI 10 making and granulomas making. Granulomas were observed on day 0, 1, 4, 7, 9, 10 and 14. Cells started to aggress on day 1 and giant cells were seen on day 4. The granuloma formed on day 9 and was maintained on day 10, however, the granuloma ruptured on day 14 which caused the cells to re-aggregate. Keywords: Granuloma, M. tuberculosis, PBMC

Abstract

This research evaluated the effect of taurine-enriched rotifers on the survival and growth of milkfish larvae. Twenty-five fertilized milkfish eggs were placed in a 250 L cylindrical fiber tank. This study used a completely randomized design with four treatments and five replications. Three days old larvae were given rotifers enriched with taurine at 0, 25, 50, or 75 mg/L. Larvae were cultured until they were 18 days old. The results showed that the taurine content in rotifers was higher in rotifer at 50 mg/L treatment, then decreased at the 75 mg/L treatment. Taurine content in the milkfish larvae aligned with taurine levels in rotifers. Furthermore, the taurine content in rotifers affected milkfish larvae' survival and body length. The highest larval survival and growth was obtained in the 50 mg/L taurine treatment. Thus, it can be concluded that taurine at 50 mg/L is the optimal rotifer enrichment dose for milkfish larvae. Keywords: growth, milkfish larvae, notochord, survival rate, taurine ABSTRAK Penelitian ini dilakukan untuk mengevaluasi pengaruh pemberian rotifera yang diperkaya taurin terhadap kelangsungan hidup dan pertumbuhan larva ikan bandeng. Dua puluh lima butir telur ikan bandeng yang telah dibuahi ditempatkan pada tangki fiber berbentuk silinder berukuran 250 L. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan lima ulangan. Larva berumur tiga hari setelah menetas diberi rotifer yang diperkaya taurin dengan dosis 0, 25, 50, atau 75 mg/L. Larva dipelihara hingga berumur 18 hari. Hasil penelitian menunjukkan bahwa kandungan taurin pada rotifer tertinggi diperoleh pada perlakuan rotifer 50 mg/L, kemudian menurun pada perlakuan rotifer 75 mg/L. Kandungan taurin pada larva ikan bandeng sebanding dengan kandungan taurin pada rotifer. Kandungan taurin pada rotifer berpengaruh nyata terhadap kelangsungan hidup dan panjang tubuh larva ikan bandeng. Kelangsungan hidup dan pertumbuhan larva tertinggi diperoleh pada perlakuan dosis 50 mg/L. Dari hasil penelitian dapat disimpulkan bahwa pemberian taurin 50 mg/L pada pengayaan rotifer merupakan dosis yang optimal untuk diberikan pada larva ikan bandeng.

Abstract

Citral is known for its antimicrobial, antioxidant, and anti-diabetic properties. This study evaluates the effects of dietary citral supplementation on glucose absorption, growth, feed utilization, and health of Pacific white leg shrimp (Litopenaeus vannamei) fed different protein levels. A 2×3 factorial experiment was conducted with two variables: protein content (30% and 35%) and citral concentrations (0, 50, and 75 mg/kg). Shrimp (3.22 ± 0.01 g) were reared in 180 L tanks (30 shrimp/tank) for 60 days. Citral supplementation increased blood glucose levels in the first two hours post-feeding, with a faster return to basal levels. Growth and feed efficiency also improved with citral diets. After stress testing, citral and dietary protein showed a synergistic effect on superoxide dismutase (SOD), with the highest level in the 75 mg/kg citral, 35% protein diet, correlating with higher post-challenge survival. Total haemocyte count (THC), phenoloxidase (PO) activity, respiratory burst (RB), and blood clotting time improved with citral supplementation, while protein level only affected RB. After Vibrio challenge, higher protein increased THC and reduced clotting time, while citral enhanced THC, PO, and RB. The highest post-challenge survival was observed in shrimp fed 75 mg/kg citral with 35% protein (p<0.05). These findings suggest dietary citral supplementation may enhance shrimp health and resilience against stress and Vibrio infection. Keywords: Citral, Cymbopogon citratus, post-prandial glucose, Litopenaeus vannamei, V. parahaemolyticus ABSTRAK Citral dikenal memiliki sifat antimikroba, antioksidan, dan anti-diabetes. Studi ini mengevaluasi efek suplementasi citral dalam pakan terhadap absorpsi glukosa, pertumbuhan, pemanfaatan pakan, dan kesehatan udang vaname (Litopenaeus vannamei) yang diberi pakan dengan kadar protein berbeda. Percobaan faktorial 2×3 dilakukan dengan dua variabel: kadar protein (30% dan 35%) serta konsentrasi citral (0, 50, dan 75 mg/kg). Udang (3,22 ± 0,01 g) dipelihara dalam tangki 180 L (30 ekor/tangki) selama 60 hari. Suplementasi citral meningkatkan kadar glukosa darah dalam dua jam pertama setelah makan, dengan penurunan lebih cepat ke tingkat basal. Pertumbuhan dan efisiensi pakan juga meningkat dengan pakan yang mengandung citral. Setelah uji stres, citral dan protein menunjukkan efek sinergis terhadap kadar superoksida dismutase (SOD), dengan kadar tertinggi pada perlakuan 75 mg/kg citral dalam diet protein 35%, yang berkorelasi dengan tingkat kelangsungan hidup pasca tantangan yang lebih tinggi. Jumlah hemosit total (THC), aktivitas fenoloksidase (PO), respiratory burst (RB), dan waktu pembekuan darah meningkat dengan suplementasi citral, sementara kadar protein hanya berpengaruh pada RB. Setelah tantangan Vibrio, kadar protein yang lebih tinggi meningkatkan THC dan mempercepat pembekuan darah, sedangkan citral meningkatkan THC, PO dan RB. Kelangsungan hidup pasca tantangan tertinggi ditemukan pada udang yang diberi 75 mg/kg citral dengan protein 35% (p<0,05). Hasil ini menunjukkan bahwa suplementasi citral dalam pakan dapat meningkatkan kesehatan dan ketahanan udang terhadap stres dan infeksi Vibrio.

Abstract

Antibiotic resistance is a problem in the health field. Potential sources of raw materials are needed to overcome this problem. Rambai (Baccaurea motleyana Muell. Arg.) is one of the Baccaurea genus which is widespread throughout Asia. Several species of Baccaurea are known for their antimicrobial properties. Extraction was performed using the maceration method with methanol as solvent. Phytochemical screening of the extract was analyzed using a standard method. The antibacterial activity was tested using the agar diffusion method (Kirby-Bauer) with extract concentrations of 2, 4, 6, 8, and 10 mg/disc. The test bacteria used were Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The results showed that the extract contained alkaloids, phenolics, and flavonoids. B. motleyana methanol extract showed antibacterial activity at a concentration of 10 mg/disc, with an inhibition zone of 11 mm. Based on these results, B. motleyana leaves have potential as an antibacterial agent.
