Legionella pneumophila is a rarely diagnosed microorganism in Serbia. It causes legionellosis, usually a mild respiratory infection. However, in some cases it can be severe and even life threatening. In June 2020, during the COVID-19 pandemic, a patient with symptoms of the aforesaid infection, namely severe pneumonia and acute respiratory distress syndrome, was admitted to the hospital. The multiplex polymerase chain reaction (PCR) test (The BioFire FilmArray Pneumonia Panel plus) detected the presence of L. pneumophila in the patient’s bronchial secretions. The specific culture for the detection of that organism, however, remained sterile. The patient’s paired sera had been sent for serology and the results in both of them came back positive for Legionella spp. 1–6, while the assays specific for each one of the 10 serogroups detected more than a fourfold increase of antibody titers in an uncommon serogroup 2 only. The patient was treated with moxifloxacin; he recovered well and was discharged after 26 days of hospitalization. Having being diagnosed with the L. pneumophila infection correctly through the multiplex PCR test, the patient was given the right therapy with moxifloxacin. The serologic assays corroborated this result and revealed the uncommon group 2, thus confirming the necessity of carrying out all the tests available to attain the exact diagnosis of legionellosis. © The Author(s) 2022.

Streptococcus gallolyticus (S. gallolyticus) bacteremia is commonly associated with endocarditis and diseases of gastrointestinal tract, especially with colorectal carcinoma. On the other side, it is rarely connected to liver disease, especially alcoholic liver disease. A 44-old patient with a history of one month fever, pre-existing heart murmur and previous alcohol abuse, was treated in Clinic for Infectious and tropical diseases, Clinical Centre of Serbia (CCS), Belgrade. The diagnose of infective endocarditis (IE) of the aortic valve caused by S. gallolyticus has been established. Despite the conducted antibiotic treatment based on antibiogram, pericardial effusion with paracardial aortic abscess was diagnosed on the 9th day of treatment. Pericardiocentesis was done and 800 mL of haemorrhagic fluid was evacuated in the Clinic for Cardiology, CCS. Unfortunately, 20th day of hospitalization the patient died. Clinical autopsy confirmed endocarditis, liver cirrhosis and chronic pericarditis. Prognosis of the outcome of treatment of patient with endocarditis caused S. gallolyticus and liver cirrhosis is not optimistic. Therefore, significant attention should be given to patients with liver cirrhosis and febrile of unknown origin. © 2019 Radovanović Spurnić et al.
