Abstract

Orangutan adalah satu-satunya kera besar yang masih bertahan di wilayah Asia Tenggara. Namun, populasi mereka di habitat liar terus menurun, dengan perkiraan menunjukkan penurunan sebesar 50% selama 60 tahun terakhir. Data mikrobiologis mengenai resistensi antibiotik Klebsiella sp. dalam feses Orangutan Kalimantan (Pongo pygmaeus) masih terbatas. Penelitian ini bertujuan untuk mengidentifikasi keberadaan Klebsiella sp. dan mengkaji pola resistensinya terhadap berbagai antibiotik dalam feses Orangutan Kalimantan. Penelitian ini melibatkan isolasi, identifikasi, dan pengujian resistensi antibiotik. Hasilnya menunjukkan bahwa tiga isolat (37,5%) positif untuk Klebsiella sp. Uji sensitivitas mengungkapkan dua pola resistensi yang berbeda di antara isolat Klebsiella sp. dari feses P. pygmaeus yang sehat di Taman Safari Indonesia, Bogor. Isolat-isolat ini menunjukkan resistensi terhadap antibiotik β-laktam tetapi tetap sensitif terhadap antibiotik golongan aminoglikosida, tetrasiklin, dan fluorokuinolon.

Abstract

Abstract Dayak onion (Eleutherine bulbosa (Mill.) Urb.) has the potential to be an immunostimulant to benefit fish health. This study aimed to evaluate the effectiveness of dietary supplementation with the powder and crude ethanol extracts of Dayak onion on the hematology and immune response parameters of Nile tilapia challenged with Aeromonas hydrophila. The research used a completely randomized design with six treatments and three replications. Nile tilapias were fed with Dayak onion (w/v) consisting of powders of 5% (P5), 10% (P10), and 15% (P15), while crude extract was 0.5% (E05) and given during rearing for 30 days. Positive control (C+) and negative control (C-) were used without Dayak onion. Nile tilapia in treatment C+, P5, P10, and P15 were injected with A. hydrophila 10⁶ CFU mL⁻1, while that in treatment C- was injected with phosphate buffered saline (PBS) intramuscularly. The results showed that the dietary with 15% powder and 0.5% crude extract significantly improved the hematology and immune response parameters compared to the control after the challenge against A. hydrophila (P<0.05). Dayak onion supplementation effectively increased the health status based on hematology and immune response parameters of Nile tilapia against A. hydrophila infection. Highlight Research Dayak onion has significant potential to improve nonspecific immunity in fish. Dayak onion improves hematology and immune response of Nile tilapia. Dayak onion can significantly regulate the immune system against A. hydrophila infection. Dayak onion significantly increases the production of the gene expression of IL-1β and TNF-α.

Abstract

Vibrio parahaemolyticus strain that produces PirA and PirB toxins is the main causative agent of Acute Hepatopancreatic Necrosis Disease (AHPND) in vannamei shrimp. This study aimed to evaluate the effect of biofloc application, probiotic Pseudoalteromonas piscicida 1Ub, and their combination on growth, immune response and resistance of vannamei shrimp infected with V. parahaemolyticus strain. This study used a completely randomized design consisting of biofloc-based system treatment with or without probiotic 1Ub and normal seawater as control. All treatment groups were challenged with V. parahaemolyticus AHPND strain at a cell density of 105 CFU mL”1 through immersion, while the negative control was reared without being pathogenic challenged. The shrimp used were in averaged body weight of 1.3 ± 0.002 g, reared for 21 days and fed five times a day at 06:00, 10:00, 14:00, 18:00, and 22:00 WIB. The results showed that the B+Pro combination challenge test treatment resulted the best growth performance (specific growth rate, absolute length gain and feed conversion ratio) (P<0.05) compared to other challenge test treatments. hrimp treated with B+Pro also showed a lower intestinal cell population of V. parahaemolyticus RfR, and significantly higher immune response values (P<0.05) than those of other challenge test treatments and K+. Furthermore, those parameters supported positive impact on final shrimp survival rates in the experiment. This study shows that the application of combination of biofloc and 1Ub probiotic bacteria can significantly protect and increase the resistance of vannamei shrimp to V. parahaemolyticus AHPND infection.
