Lactococcus is part of our normal GI flora because it is intrinsic in foods that we eat, especially dairy products. Lactococcus cremoris and Lactococcus lactis are the most well-described species that we ingest. Lactococci have not be found to have unique receptors for the urinary tract cells (unlike Staphylococcus saprophyticus) and have not be known to be UTI pathogens. That being said you need to consider how this specimen was collected, is the patient symptomatic, is the organism present in multiple specimens that are properly collected? Depending on host immunity, the presence of foreign bodies, other practices, this could be clinically significant in this patient.
We hope that we were able to answer your question.
