You are goofy. And none too familiar with presentations.
Staphylococcus aureus can cause toxic shock syndrome. One symptom of toxic shock is vomiting. Hence, vomiting can be a sign of bacterial infection.
Vomiting can also be a sign of food poisoning, which also is caused by bacteria.
As far as presentations go, my knowledge of them is strictly limited to the descriptions in the medical literature--I am a researcher, not clinician.
