Negative, IgM positive and IgG positive samples (A) as well as 2 serum samples taken from patient #AS (B) and 2 serum samples taken from patient #LH (C) were subjected to Indirect IFT (Euroimmun) to detect IgM and IgG antibodies against Sandlfy fever Sicilian virus. Type of antibodies (IgG and IgM) and sample numbers are indicated.As can be seen in panel B, specific staining in the cells cytoplasm is observed in sample II, but not in sample I for both IgM and IgG, indicating IgM and IgG seroconversion. Since only some of the cells on the slide are infected by Sandlfy fever Sicilian virus (according to the Euroimmune IFT protocol), not all of the cells are stained. Panel C shows specific staining in sample II only for IgM and not IgG, suggesting IgM seroconversion.842645297180IgGIgMSample ISample II00IgGIgMSample ISample IIPatient # LH IFA serology for Sandlfy fever Sicilian virus showing seroconversion in IgM ................
