[Mediterranean spotted fever. A case report and review of literature]
Abstract:
A patient was documented as having mediterranean spotted fever by indirect immunofluorescence antibody test and inoculation of the patient's blood into the yolk sac of embryonated hen egg. In general, the infection of rickettsia conorii is caused by bite of infected tick. The infection in this case, however, occurred in a laboratory, so the transmitting route might be infected aerosol via impaired mucous membrane.
Insights
Mediterranean spotted fever, caused by Rickettsia conorii, was diagnosed using serological tests and embryonated hen egg inoculation. This case suggests potential laboratory-acquired aerosol transmission via mucous membranes, differing from typical tick-borne routes.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Mediterranean spotted fever is a tick-borne illness caused by Rickettsia conorii.
- Typical transmission occurs through the bite of infected ticks.
Observation:
- A laboratory worker was diagnosed with Mediterranean spotted fever.
- Diagnosis was confirmed via indirect immunofluorescence antibody test and embryonated hen egg inoculation.
Findings:
- The patient's infection occurred within a laboratory setting.
- The route of transmission was not a typical tick bite.
Implications:
- This case highlights a potential alternative transmission route for Rickettsia conorii: aerosolized particles in a laboratory environment.
- It underscores the importance of stringent biosafety protocols when handling infectious agents like Rickettsia conorii.
- Further investigation into non-vector-borne transmission of Rickettsia conorii in laboratory settings is warranted.
