Abstract
We present a case of a 78-year-old female patient who was admitted to the medical intensive care unit because of high fever, weakness and abdominal pain. Bacterio-logical studies showed sepsis and allowed the isolation of Actinomyces odontolyti-cus and Abiotrophia species as causative agents. Further investigation led to a diag-nosis of liver abscess from which there was also isolated Haemophilus parainfluenzae, Streptococcus intermedius and Strepto-coccus anginosus, as well as the above mentioned bacteria. All named microor-ganisms represent a part of normal oro-pharyngeal flora and may cause abscesses or sepsis under certain circumstances. As far as we know, liver abscess due to Abio-trophia species was never reported.
Highlights
Actinomyces odontolyticus, Abiotrophia species, Haemophilus parainfluenzae, Streptococcus intermedius and Streptococcus anginosus represent a part of normal oropharyngeal flora and may cause abscesses or sepsis under certain circumstances. [1,2,3,4]
Needle aspiration of the abscess was performed, pus was evacuated, and bacteriological studies allowed the isolation of the following microorganisms: Actinomyces odontolyticus, Abiotrophia species, Haemophilus parainfluenzae, Streptococcus anginosus and Streptococcus intermedius
H. parainfluenzae is an uncommon agent of human infection, but it has been found to be associated with endocarditis, bacteriemia, soft tissue infection, septic arthritis, meningitis and brain abscesses, osteomyelitis, upper respiratory tract infections and rarely liver abscess
Summary
Actinomyces odontolyticus, Abiotrophia species, Haemophilus parainfluenzae, Streptococcus intermedius and Streptococcus anginosus represent a part of normal oropharyngeal flora and may cause abscesses or sepsis under certain circumstances. [1,2,3,4]. A 78-year-old woman presented with high fever up to 41 °C, chills and shivering of three days duration She had no history of severe or chronic disease, and she sometimes used diclofenac due to knee pain. Her APACHE II score was 18 and her Glasgow Comma Score (GCS) was 14. An abdominal ultrasound and CT scan showed a large liver abscess and two concrements in her gallblader. Her urine culture revealed Escherichia coli 105. Needle aspiration of the abscess was performed, pus was evacuated, and bacteriological studies allowed the isolation of the following microorganisms: Actinomyces odontolyticus, Abiotrophia species, Haemophilus parainfluenzae, Streptococcus anginosus and Streptococcus intermedius. The postoperative course was uneventful and she was discharged home on the seventh postoperative day
