This organism is gram(+) cocci in pairs that are often Lancelet-shaped (or "cat-eyes") Streptococcus pneumoniae These colonies were slow growing, small, entire and show soft beta hemolysis. Plump, Gram-negative coccobacilli, lying singly, in pairs and short chains, are seen on gram stain. Most strains are chemically non-reactive except for a positive oxidase reaction and acid produced from dextrose and maltose. What is the name of the isolate? Kingella kingae The oxidase test i...
