Abstract

Quercetin is an important phytochemical that belongs to the flavonoid group of plant pigments. It has potential benefits as an antioxidant, antiviral, and anti-inflammatory agent. However, the utilization of quercetin in aquaculture is not optimal. Hence, this study conducted a literature review to analyze the potential benefits of quercetin in aquaculture, especially for fish and prawn. Results showed that quercetin can be isolated from herbs using several methods, including sonication, maceration, and fractionation. Its amount in plants can be potentially determined using high-performance liquid chromatography and thin-layer chromatography. Some of the plants containing high quercetin levels include shallot, garlic, apple skin, guava leaves, green tea, chia seeds, and desert rose flower. In aquaculture, quercetin can be applied to increase the ideal body weight, feed conversion ratio, and condition factor of aquatic cultured species and serves as an antioxidant, antistress, strengthening probiotic and an antiinfective agent. Latest research showed that quercetin benefits the immunity of goldfish against furunculosis. Furthermore, quercetin shows potential in prawn industry as an antioxidant protection that improves the meat quality. To date, the potential benefits of quercetin have not been widely utilized in aquaculture. The minimum utilization can be attributed to the lack of a systematic review regarding its potency either on fish or prawn. Hence, this study provides the essential review of quercetin in aquaculture.

Abstract

Antibiotic resistance is a global problem related to human and animal health. Antibiotic resistance occurs when bacteria acquire a resistant gene that allows them to survive when exposed to the antibiotic. Production animals and their production environment are considered as a reservoir for the emergence of resistant bacteria that transfer to humans either directly or indirectly. Narmada Subdistrict in West Lombok is one of the districts that have a large population of poultry. One of the infectious diseases that often attacks poultry and is treated using antibiotics is Salmonella sp. This study aims to determine the data on antibiotic resistance in Salmonella sp. This resistance data can be used as an effort to prevent antibiotic resistance against Sallmonella sp bacteria in layer chicken farms in Sesaot, West Lombok. This research using eight Salmonella sp. isolates, they were tested with antibiotics PenicillinG, Tetracycline and Oxytetracycline. Bacterial resistance test was carried out after the results obtained from the identification of bacteria, Salmonella sp. The results obtained from eight Salmonella sp isolates tested for antibiotic resistance, antibiotics were categorized as susceptible to Penicillin G (75%), Oxytetracycline (12.5%), and Tetracycline (12.5%). Antibiotics were categorized as intermediates consisting of Penicillin G (0.0%), Oxytetracyline (12.5%), and Tetracycline (50%). and Antibiotics categorized as resistant consisted of Penicillin G (25%), Oxytetracycline (75%), and Tetracycline (37.5%).
