Mutualism of a Bengal Tiger- A very powerful antibiotic‚ Bacilli is a type of bacteria belonging to the Enterobacteriaceae family. Specifically‚ Pantoea agglomerans of the bacilli family are helpful by producing a broad spectrum antibiotic andrimid. This kills many harmful bacteria that a tiger may ingest from its prey by blocking a critical step in fatty acid biosynthesis. This helps protect the tiger from such dangers like E. coli and samonella poisoning. Parasitism-An example of parasitism is
