yea, eikenella is a gram neg coccobacillus, part of HACEK group causing endocarditis in rare cases. Also they are slow growing organisms hence may show as negative blood culture.
but what is up with the neurological finding?

Emboli to the CNS often presents as a focal neurological deficit or a stroke. very common with this group of organisms. definitly this is the answer
