They are found in the human colon.

Syndromes

Bacteremia usually in association with a GI pathology. As is always the case, a hodgepodge of odd infections. Evidently the most common genera of nonspore-forming anaerobic gram-positive rod in intra-abdominal infections.

Bacteremia is associated with a high mortality rate, around 1 in 4 die.

Treatment

Who knows. Report suggest "susceptible to amoxicillin/clavulanate cefoxitin, metronidazole, piperacillin/tazobactam, ertapenem and meropenem, 91% were susceptible to clindamycin, 74% to moxifloxacin and 39% to penicillin (PubMed).

But. Mono-therapy with zosin for bacteremia is associated with increased mortality; metronidazole may be the best bet (PubMed)
