An alcoholic that drinks too much has a pulmonary abscess and caries in teeth. What is the causative agent?

Not sure if you're talking about Vincent's stomatitis (or "trench mouth"). I was going to guess Fusiforms (a type of anaerobic gram negative rod). Borrelia vincentii has also been implicated in trench mouth.

However, if you're talking pulmonary abscesses, it may not be that particular syndrome, although most lung abscesses are caused by anaerobes, and fusiform gram negative rods are indeed anaerobes...

How am I doing? :|

YOU ARE DOING GREAT....
Yet it is a common clue of klebsiella to mention ALCOHOLIC + LUNG ABSCESS. However, what troubles me here is CARIES. That makes my mind go to that sth causes tooth erosion such as acid from stomach....what follows is that the causative agent is introduced to the lung by aspiration...NOW WHAT IS THIS AGENT??
Thanks for the link
