✦ Synopsis

Since April 1986, microimmunofluorescence assays have been employed at the Department of Virology at the National Bacteriological Laboratory in Sweden to investigate the presence of specific IgM and IgG antibodies to C. burnetii and R. conorii in patient sera. A total of 111 patients with suspected rickettsial disease were investigated during the time period April 1986-November 1988. In 23 patients specific IgM was detected--in 9 to C. burnetii and in 14 to R. conorii. In thirteen of the IgM-positive patients a significant rise in specific IgG between acute and convalescent sera was also seen. All 23 patients had been travelling abroad prior to onset of disease. The microimmunofluorescence test was a simple and reliable tool in the detection of specific IgM for a rapid and accurate diagnosis of C. burnetii-and R. conorii-infections early in the course of disease.

In 1982, we isolated 20 strains of echovirus type 33 (EV33) from 18 patients. We studied the humoral response to EV33 of 2,437 subjects from whom at least one serum was available during the same year. In 388 subjects with the neutralizing antibody level at 64 or more, we assayed the EV33 IgM antibod
