Sažetak:
Rickettsia are gram-negative, pleomorphic, obligate intracellular bacteria transmitted by arthropods, causing human diseases. Due to unspecific clinical symptoms, the disease in humans can be misdiagnosed and undetected. Rodents are suggested reservoir hosts for certain rickettsiae. The most important diagnostic methods for rickettsiae are still serological: immunofluorescence, ELISA, western blot. However, differentiating rickettsial species by serology is difficult due to cross-reactivity between the species (owing to shared protein epitopes and lipopolysaccharides). So, molecular diagnostics of rickettsiae is becoming more important, although taking adequate human samples for molecular diagnostics is time limited due to administering antibiotic therapy and short bacteremia. With the newly established molecular diagnostics at the University Hospital for Infectious Diseases "Dr. Fran Mihaljević" in Zagreb, we detected Rickettsia spp. in human and animal samples. Samples were taken from a patient returning from a trip to Africa and 77 tissue samples of small wild rodents from three different localities in Croatia (Lipovljani, Plitvice, Medvednica). A conventional screening PCR targeting the Rickettsia spp. partial outer membrane protein B gene (ompB) was performed for all samples. The positive result was obtained from the patient’s wound swab sample. Sequencing confirmed that the infection in the patient was caused by Rickettsia africae. Rickettsia spp. was demonstrated in 1.3% of total 77 rodent samples. Given the increasing number of tourists in Croatia and Croatian citizens traveling to Africa, it is necessary to include rickettsioses in the differential diagnosis for the patients returning from a trip to Africa, proving wound swabs to be adequate sample source for the detection of the pathogen. Further studies are needed to determine the significance of small rodents as reservoirs for rickettsiae in different areas in Croatia.
