  "account": "Antimicrobial resistance is a pressing issue in shrimp hatchery environments in Bangladesh, where Vibrio species pose a significant threat to larval development. A recent study examined the antibiotic resistance patterns of nineteen different Vibrio species found in water-flow systems and postlarvae from hatcheries in Coxs Bazar. The most dominant group was the Harveyi clade, which included V. alginolyticus, V. rotiferianus, and V. harveyi. These Vibrio isolates displayed high resistance to erythromycin, ampicillin, and streptomycin, but were susceptible to chloramphenicol, nitrofurantoin, and gentamicin. Seven antibiotics, including trimethoprim-sulfamethoxazole, ampicillin, and erythromycin, were found to be poorly active against the Vibrio species, indicating their ineffectiveness in treating vibriosis outbreaks. Over half of the isolates had a multiple antibiotic resistance index greater than 0.2, with 67.8% categorized as multidrug-resistant. This multidrug resistance increased along the water-flow systems, with postlarvae exhibiting the highest values, suggesting that antibiotic contamination is prevalent within hatchery systems. The screening of resistance genes revealed sul2 and tetC as the most prevalent, and association analysis showed cross-resistance patterns among antibiotics, along with a concordance between trimethoprim-sulfamethoxazole and streptomycin resistance due to the presence of sul2 and strA-strB genes. The study provides crucial baseline data on Vibrio diversity and resistance burden, and highlights the need for antibiotic stewardship policies and monitoring strategies that adhere to a One Health approach in shrimp hatchery systems.",
  "summary": "Vibrio species are ubiquitous in shrimp hatchery systems, where their opportunistic pathogenic characteristics threaten the vulnerable larval stage, and antibiotics are routinely applied for disease control and prevention. Therefore, studying Vibrio composition and its antibiotic resistance burden is critical for hatchery environments and public health. The present study characterized Vibrio…",
