S. Radulovic et al., PREVALENCE OF ANTIBODIES TO SPOTTED-FEVER GROUP RICKETTSIAE ALONG THEEASTERN COAST OF THE ADRIATIC SEA, Journal of clinical microbiology, 31(8), 1993, pp. 2225-2227
A seroepidemiological survey in coastal Croatia detected antibodies re
active with Rickettsia conorii in 4.2% Of sera by immunofluorescence a
ssay and in 5.0% of sera by enzyme immunoassay. Western immunoblotting
demonstrated antibodies to the 120-kDa surface protein in all 20 posi
tive serum samples examined and to rickettsial lipopolysaccharide in 3
of these serum samples. Humans in this area are clearly being exposed
to spotted fever rickettsiae.
