Lactococcus garvieae in Rural Alabama: A Case Report

Lactococcus (L.) garvieae is a gram -positive coccus that has been found in various aquatic and terrestrial animals, as well as in dairy products, and is considered a potential zoonotic bacterium. The pathogen has been recognized as an emerging opportunistic human pathogen, often associated with the ingestion of raw seafood. The most common presentation of L. garvieae infection in humans is infective endocarditis, but it has also been found to have associations with other clinical manifestations. The following is a case report of a 6 -year -old male with infected bilateral leg abrasions that occurred after playing in a local creek near his home in northern Alabama, which had livestock including goats, cows, and horses. Wound culture indicated that the bacteria was L. garvieae, which was found to be sensitive to ceftriaxone, levofloxacin, linezolid, tetracycline, tigecycline, and vancomycin and resistant to clindamycin. The patient was treated with oral cephalexin and topical gentamicin for ten days, after which there appeared to be an overall improvement in wound healing.
