And again we see someone equating bacteria to kind
This is a bit unfair - neither slevesque nor ICANT equated bacteria with kind - they simply said that something was still a bacteria. Had they a more detailed knowledge of bacterial systematics, they might have said 'It's still a bacilliales' or 'It's still a staphylococcaceae' or even, in this case, 'it's still Staphylococcus aureus'.
