Vibrio

Vibrio is a genus of Gram-negative, motile, comma-shaped bacteria that naturally inhabit coastal and estuarine waters worldwide (Centers for Disease Control and Prevention, 2023) [1]. The genus includes several species pathogenic to humans, most notably Vibrio cholerae, which causes the acute diarrheal disease cholera through the production of cholera toxin (StatPearls, 2023) [2]. Other clinically significant species include Vibrio parahaemolyticus, a leading cause of seafood-borne gastroenteritis, and Vibrio vulnificus, which can cause life-threatening septicemia and necrotizing fasciitis (StatPearls, 2023) [3]. From a pharmacological perspective, Vibrio is not a single molecular target but a complex organism containing multiple essential proteins and pathways targeted by antimicrobial agents (Mayo Clinic, 2023) [4]. Effective management of Vibrio infections typically involves a combination of aggressive fluid replacement and antibiotic therapy to reduce the duration of illness and pathogen shedding [2].

Antibiotics targeting Vibrio species function through various mechanisms: tetracyclines (e.g., doxycycline) and macrolides (e.g., azithromycin) inhibit protein synthesis by binding to the bacterial 30S or 50S ribosomal subunits; fluoroquinolones (e.g., ciprofloxacin) inhibit DNA gyrase and topoisomerase IV to prevent DNA replication; and beta-lactams (e.g., ceftriaxone) interfere with peptidoglycan synthesis in the bacterial cell wall (StatPearls, 2023; Mayo Clinic, 2023) [2, 4].
