Rickettsiae of the spotted fever group in Hungary
Folia Parasitologica
|January 1, 1979
Abstract:
Rickettsiae were detected by haemocyte test in 7.2% of Dermacentor marginatus and 4.7% of D. reticulatus ticks collected in Hungary. Six strains of rickettsiae were isolated from positive specimens. These rickettsiae according to CFR are closely related, probably identical with R. slovaca and they represent the first rickettsiae of the Spotted Fever group found in that country.
Insights
Spotted Fever group rickettsiae were found in Hungarian ticks. Six strains, likely Rickettsia slovaca, were isolated, marking the first detection of this group in the country.
Area of Science:
- Veterinary Entomology
- Bacteriology
- Epidemiology
Background:
- Ticks are significant vectors of various pathogens.
- Rickettsia species, particularly those of the Spotted Fever group, pose public health concerns.
- Previous studies have not reported Spotted Fever group rickettsiae in Hungary.
Purpose of the Study:
- To detect and characterize Rickettsia species in ticks collected in Hungary.
- To identify the specific Rickettsia species and their prevalence.
- To establish the presence of Spotted Fever group rickettsiae in Hungary.
Main Methods:
- Haemocyte testing was performed on Dermacentor marginatus and D. reticulatus ticks.
- Isolation of rickettsial strains from positive tick specimens.
- Phylogenetic analysis based on CFR (Centipede-Flea-Rodent) to determine species relatedness.
Main Results:
- Rickettsiae were detected in 7.2% of Dermacentor marginatus and 4.7% of D. reticulatus ticks.
- Six rickettsial strains were successfully isolated.
- The isolated rickettsiae showed close relation to Rickettsia slovaca.
Conclusions:
- This study reports the first detection of Spotted Fever group rickettsiae in Hungary.
- The identified rickettsiae are closely related or identical to Rickettsia slovaca.
- The findings highlight the presence of potential tick-borne disease agents in Hungary.
