Prolonged Lactobacillus Bacteremia With Abdominal Abscesses Secondary to Traumatic Injuries From Pet Dogs: A Case Report

Lactobacillus casei is a non-spore forming gram-positive rod considered to be normal flora of the oropharynx and gastrointestinal tract. Additionally, Lactobacillus spp. are commonly used as probiotics and other commercial products. Invasive infections are rarely encountered and have been associated with underlying immunosuppression or malignancy. Here, we present a case of prolonged Lactobacillus bacteremia and multiple intra-abdominal abscesses likely as a result of injuries associated with pet dogs.
