The emergence of the popular, physically demanding and highly nature-interactive sport of orienteering was marked in Sweden by an elevated rate of sudden unexpected cardiac deaths in young competitors during the years 1979-92, with a common underlying cause or causes suspected. Subsequently, sera were collected during 1992-93 from the elite segment of orienteers holding a nationally ranked position, and a survey compiling various epidemiological data was performed. In this study, a total of 1136 sera were analyzed by indirect-fluorescent antibody assay for the presence of IgG antibodies against 3 Bartonella spp.: B. henselae, B. elizabethae and B. quintana. In total, 31% (355/1136) were seropositive for at least 1 species of Bartonella, with titers ranging up to 1/512; 350/1136 (31%) had antibodies against B. elizabethae, 34/1136 (3.0%) against B. henselae and 16/1136 (1.4%) against B. quintana. Males and females showed equal rates of 31% seropositivity to Bartonella spp. (males 241/766; females 114/370). In comparison, 322 time-matched sera from healthy blood donors had antibodies to Bartonella spp. in 6.8% of cases (p < 0.001). The observed high prevalence of Bartonella spp. antibodies found in Swedish elite orienteers may be indicative of a connection with risk factors for the development of myocarditis and sudden unexpected cardiac death.
