Leuconostoc
species are rare causes of bacteremia and are commonly mistaken for
Streptococcus
species. Due to their inherent resistance to commonly used drugs, they are often overlooked resulting in poor and sometimes lethal outcomes. While there are not many reported cases of this bacterial infection,
Leuconostoc
species are important to consider when faced with a highly drug-resistant bacterial strain. We present here a case of a 29-year-old male who presented with an out-of-hospital cardiac arrest, initially resuscitated but ultimately succumbing to his illness. This is a unique case in which our patient was subsequently found to have a rare bloodstream infection with
Leuconostoc pseudomesenteroides.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
