The prevalence of Legionella and mycoplasma seropositivity in the elderly in Cape Town
… was high, with 88,4% (677/766) taking part. Seropositivity for both of these organisms was low. There were 17 participants (2, 51 %) with antibodies to mycoplasma (IgG only in 8, IgM only in 1, and both IgG and IgM in the remaining 8). Titres were low with only 1 IgM titre of 16, and only 3 …

Συχνότητα μόλυνσης με κυτταρομεγαλοϊό, yersinia enterocolitica και toxoplasma gondii, ασθενών με μεσογειακή αναιμία και οικείων τους
… patients were seropositive to CMV, whereas the seropositivity rate in the control subjects was 59,3% (p<0,001). Also 97,3% of the household contacts were positive for antibodies against CMV, whereas only 66,4% of the control subjects were positive (p<0,001). These findings indicate that not only …
