Abstract

Informasi dan pengetahuan masyarakat yang masih minim mengenai antibiotik burung hias dapat menimbulkan penyalahgunaan dan resistensi antibiotik. Staphylococcus koagulase positif merupakan salah satu bakteri Gram positif yang bersifat patogen dan dapat menginfeksi burung lovebird. Tujuan penelitian ini adalah mengetahui resistensi Staphylococcus koagulase positif yang diisolasi dari swab kloaka burung lovebird terhadap beberapa antibiotik yang berbeda. Isolat bakteri yang digunakan sebanyak empat buah dan diuji terhadap antibiotik gentamisin, eritromisin, siprofloksasin, tetrasiklin, dan doksisiklin menggunakan metode difusi cakram menurut Kirby-Bauer. Interpretasi hasil dan penentuan sifat kepekaan mengacu pada Clinical and Laboratory Standards Institute (CLSI 2018). Hasil uji resistensi yang didapatkan bervariasi. Sifat resistensi hanya didapatkan terhadap gentamisin pada isolat 4. Intermediet didapatkan terhadap gentamisin pada isolat 1, serta terhadap eritromisin dan siprofloksasin pada isolat 4. Isolat 2 dan 3 menunjukkan kepekaan sensitif terhadap gentamisin, eritromisin, siprofloksasin, tetrasiklin, dan doksisiklin.

Abstract

The study aimed to evaluate the effect of the water application of probiotic Bacillus sp. DMP13 on the growth and stress response of giant freshwater prawn larvae Macrobrachium rosenbergii. The larvae used in this experiment were 1-day-old larvae post-hatching with an average body weight of 2.7±0.6 mg and an average length of 2.1±0.1 mm. The larvae were reared in 2 L plastic tanks with a density of 100 L-1 for 21 days. The study was conducted using 4 treatments with three replications of each, namely A (control without probiotic), B (Bacillus sp. DMP13 with cell concentration of 102 CFU (colony forming unit) mL-1), C (Bacillus sp. DMP13 with 104 CFU mL-1) and D (Bacillus sp. DMP13 with 106 CFU mL-1). Probiotic was applied in the rearing media on days 9th up to 18th with 3 days intervals. The results showed that application of Bacillus sp. DMP13 with a cell density of 102 CFU mL-1 was able significantly increased the absolute larvae weight (29.67±1.88 mg), increased larval survival in stress concentrations of 1,250 μL L-1 of formalin solution (the highest larval survival rate 98.3±2.9%). Treatment with 102 CFU mL-1 probiotic cell addition also increasing the total bacterial viable count in the media (the cell density reached 5.99±0.28 log CFU mL-1). However, other parameters such as the larvae stage index, survival rate, and absolute length of the larvae with probiotic treatments were not significantly different from those of control.

Abstract

Staphylococcus aureus (S. aureus) is one of the common causes of bovine mastitis worldwide. Inappropriate use of antimicrobials in cattle farms contributes to the increase of the antimicrobial resistance of S. aureus. This study aimed to investigate the antimicrobial resistance profiles of S. aureus isolated from cattle milk. Twelve S. aureus isolated from cattle milk in Bogor, Indonesia, were tested against seven antimicrobials using Kirby-Bauer disk diffusion susceptibility test. The results revealed that 58.3 % of isolates were multidrug-resistant S. aureus. The S. aureus isolates were resistant to penicillin G (66.7 %), ampicillin (66.7 %), vancomycin (58.3 %), and bacitracin (58.3 %). Most of the isolates were susceptible to ciprofloxacin (91.7 %), gentamicin (66.7 %), and chloramphenicol (66.67 %). If clinically indicated, treatment of mastitis should consider the antimicrobial susceptibility of the causative agent.

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

Catfish Clarias sp. is one of the leading commodities in demand and has economic value. Low survival due to cannibalism and disease is a serious problem. To overcome these problems is application of bioflocs and probiotics Bacillus NP5. This study aimed to analyze the appropriate dose of Bacillus NP5 probiotic addition to the biofloc system to improve the health status, growth performance, water quality, and resistance to A. hydrophila. The catfish fry (Clarias sp.) with an average weight of 1.79±0.05 g was used in the experiment for 40 days, reared in tanks with the dimension of 60×30×35 cm3. The experiment applied a completely randomized design (CRD) of five treatments with three replicates, namely KN (negative control), KP (positive control), BFT (biofloc application without probiotic bacteria), BFT4 (biofloc application with Bacillus NP5 104 CFU mL-1), BFT6 (biofloc application with Bacillus NP5 106 CFU mL-1). Treatments tested were challenged with A. hydrophila density 104 CFU mL-1 by immersion, except the negative control. After 40 days of rearing, biofloc and Bacillus NP5 treatments had a significant effect (P < 0.05) on growth performance, immune response, water quality, total bacteria in water and the gut compared to the control treatment (P < 0.05). In addition, total A. hydrophila in liver, kidney and water were lower (P < 0.05) in BFT4 and BFT6 treatments than the control. The conclusion of this study is that the bioflocs supplemented with Bacillus NP5 improved the growth performance, immune response and resistance of catfish to A. hydrophila infection.
