“…The gastrointestinal tract and the hepatopancreatobiliary system are the most frequently reported infection sites, but urinary tract and osteoarticular infections have also been reported [ 1 ] . Very few cases of sinusitis with R. ornithinolytica have been reported [ 2 , 3 ] ; in these cases, R. ornithinolytica caused severe pansinusitis or spread to adjacent facial structures. In our patient, the odontogenic sinusitis rapidly spread and caused orbit cellulitis, a subperiosteal abscess, pachymeningitis and intracranial epidural empyema.…”

Raoultella ornithinolytica is an encapsulated, Gram-negative, nonmotile, rod belonging to the Enterobacteriaceae family. Infections involving the gastrointestinal tract and the hepatopancreatobiliary system are most frequently reported, especially in immunocompromised patients. The authors present an unusual case of acute complicated sinusitis with orbital and intracranial involvement caused by R. ornithinolytica. The infection was rapidly progressive, even though the patient was a healthy, young person without any co-morbidities. The patient’s condition improved after antibiotic treatment and multiple ophthalmic and sinus surgeries.

Raoultella ornithinolytica is a bacterium belonging to the family Enterobacteriacae. It is a rare but emergent cause of human pathologies especially in immunocompromised patients. We described the first case in the literature of isolated external otitis sustained by Raoultella ornithinolytica in an immunocompetent host. A 54-year-old Caucasian man with a history of previous myringoplasty came to our attention reporting otalgia and otorrhea. We performed right ear swab for culture examination, meanwhile we started empirical therapy with topic administration of neomycin, without any clinical improvement. The cultural examination showed the presence of a Raoultella ornithinolytica infection. After ten days of treatment with oral ciprofloxacin and topic levofloxacin, there was the complete resolution of pain and inflammation. Raoultella ornithinolytica must be taken into consideration as an emergent cause of human infection, also in case of external otitis. Infection can be severe and can occur both in immunocompromised and in immunocompetent hosts. Culture test is mandatory to choose the proper therapy and avoid potential severe complications.

A case report of community-acquired Raoultella ornithinolytica infection in a healthy, young individual

Background Raoultella ornithinolytica is a Gram-negative bacillus that resembles Klebsiella. This bacterium is present in many soil and aquatic environments and is a major causative agent of healthcare-associated infections (HAIs) in medical staff. Clinically, it has been reported to contribute to nosocomial infections in patients that include but are not limited to gastrointestinal, skin, and genitourinary tract infections. These complications are most common in hospitalized patients with underlying immunodeficiency, multiple comorbidities, or those receiving invasive surgery. Case presentation We present a case of a 25-year-old patient with a R. ornithinolytica infection. The patient had no history of any disease. Her main complaints were high fever, a scattered maculopapular rash, and superficial lymph node enlargement (SLNE). Peripheral blood samples were collected for high-throughput sequencing analysis to identify pathogenic microorganisms. The results confirmed a R. ornithinolytica infection, which was treated successfully using meropenem. Loratadine was also administered to treat the patient’s compromised skin condition caused by an allergic reaction. Conclusions To our knowledge, this is the first case of a systemic maculopapular rash and superficial lymphadenopathy caused by a R. ornithinolytica infection acquired at the community level. Based on this case, we recommend a combination of antibiotic and antiallergic drugs to treat a R. ornithinolytica infection and associated allergic reaction to the bacteria.
