Clin Infect Dis, 22(6):944-950, June 1996

ABSTRACT: The concentrations of mercury in saliva and feces and the resistance pattern of the gastrointestinal microflora were investigated for 20 subjects. Ten patients, with a mean number of 19 amalgam surfaces, had all amalgam fillings removed during one dental session. Ten subjects without amalgam fillings served as control group. Saliva and fecal sample were collected before amalgam removal and 2, 7, 14, and 60 days afterwards.  Mercury levels in saliva and feces correlated significantly with the number of amalgam surfaces. In the amalgam groups there was an increase in the relative number of intestinal microorganisms resistant to mercury, ampicillin, cefoxitin, erythromycin, and clindamycin on days 7-14. A significant correlation between the prevalence of mercury resitance and multiple antimicrobial resistance in intestinal bacterial strain was observed.

COMMENT: Ten subjects and ten controls is an extremely small sample in human studies because, as noted by the authors, the large number of variables to condsider in humans. In view of this small sample, the significance of the findings in intestinal flora magnifies tremendously. The findings of mercury correlation in saliva and feces adds further confirmation to significant human exposure to amalgam mercury.

QUOTE: "Antibiotics used to treat various infections often were ineffective in the presence of abnormal localized deposits of heavy metals like Hg and Pb, which were often observed to coexist with Chlamydia trachomatis, Herpes simplex types I & II, Cytomegalovirus (CMV) and other microorganism".
