Abstract:
Between 4 May and 8 August 2002,46 cases of acute fever were reported near the Black Sea region in northern Turkey. The infection was treated rapidly and successfully with tetracyclines, so clinical diagnosis of rickettsial or ehrlichial infection was considered. Analysis of serum and blood samples taken from 19 patients identified the causative organism as Coxiella burnetii; 7 cases were reported as acute Q fever and 8 as seropositive for past infection. The most common clinical symptoms among the acute cases were vomiting (100.0%), nausea (85.7%), diarrhoea (57.1%), fever (42.9%), abdominal pain (42.9%) and headache (42.9%). Liver enzymes were elevated in all patients. It is considered that epidemiological investigation for Q fever will be essential in the affected region in future.
Insights
An outbreak of acute fever in Turkey was identified as Q fever, caused by Coxiella burnetii. Prompt treatment with tetracyclines was effective, highlighting the need for future Q fever surveillance in the region.
Area of Science:
- Infectious Diseases
- Epidemiology
- Microbiology
Background:
- An outbreak of acute febrile illness occurred in northern Turkey near the Black Sea region between May and August 2002.
- Initial clinical suspicion pointed towards rickettsial or ehrlichial infections due to rapid response to tetracyclines.
Purpose of the Study:
- To identify the causative agent of the acute fever outbreak.
- To characterize the clinical presentation and serological status of affected individuals.
Main Methods:
- Serum and blood samples were collected from 19 patients presenting with acute fever.
- Laboratory analysis was performed to identify the etiological agent and assess past infection status.
Main Results:
- Coxiella burnetii was identified as the causative organism.
- Seven cases were diagnosed with acute Q fever, and eight individuals were seropositive for past infection.
- Common symptoms included vomiting, nausea, diarrhea, fever, abdominal pain, and headache, with all patients exhibiting elevated liver enzymes.
Conclusions:
- The outbreak in northern Turkey was attributed to Coxiella burnetii, the agent responsible for Q fever.
- Epidemiological investigation and surveillance for Q fever are crucial for this region in the future to prevent and manage potential outbreaks.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
