Which one of the following bacterial species is responsible for the Scombroid fish poisoning?
In microbiology, microbial physiology dictates that growth regulation and host interactions follow molecular programs. Therefore Photobacterium phosphoreum is correct as it corresponds to prokaryotic strategies, supported by mechanistic studies and conserved across related systems.
Ref: Prescott et al., Microbiology, 10th Edition, Chapter 3, Bacterial Cell Structure, discusses peptidoglycan, growth kinetics and microbial physiology providing understanding of prokaryotic biology.
