The protozoan Toxoplasma gondii is usually harmless, opportunistic parasite in humans but beside that it continues to cause significant morbidity and mo+Iity. While generally most postnatal infection of healthy immunocompetam persons da not cause any clinical manifestations. in small proportion

symptoms as fever, lethargi and lymphadenitis may occur. However, an infection leads to the formation of cysts and thus to immunity. Coleffed sera from 2835 woman in reproductive period ticb were tested oh anti-Toxoplasma gondii antibodis between 1994. and 1997. were examined. IgG and IgM antibodies we determined by ELISA (Toxonosika IgGIi and Toxonostika IghlrI Organon Tehnika, Boxtel, NL). Antitoxoplasma antibodys (IgG and/or IgM) were detected in 1335 persons (47,IK). Only IgG antibodies were detected in 1213 persons (42,8%) and the part of Igh4 only antibodis were detected in 52 cases (l,82%). Both IgG and IgM were detected in 99 cases (3.5%). In the next step srmm with positive IgM antibodies were examined for activ toxoplasmosisinfection. Our expectationscorrespond with this epidemiologicalstudie‘s results and once again it show that congenital toxoplasmosis can be markedlly reduced by serologic srweillance of fertile and pregnant women.

IN PREHISTORIC POPULATIONS EUROPE: REVIEW AND RECENT

During the past years we had several opportunities to examine various human remains of prehistoric periods of Central Europe for parasites, the most famous of them being the spectacular wellpreserved Neolithic glacier mummy (at least 5200 years old), found in the Tyrolese Alps in an al&de of 3200 m. The body was investigated for ectoparasites, and samples from the jejunum as well as from the colon were examined for intestinal parasites. Moreover, we have examined and have continuously been studying large numbers of samples of prehistoric human faeces excellently preserved in salt-mineral which were left in the mines by prehistoric Alpine salt miners in the first millenium BC. After rehydration with 0.3% trisodium phosphate and/or fixation of the samples in SAF various diagnostic procedures were applied including staining, microscopy and teSts for coproantigens. The colon of the Neolithic mummy proved to contain large numbers of eggs of Ttichunk rrichium; they represent by far the oldest evidence of whipworm in a human corpse. In the excrements of the salt miners eggs of Ascuti fumbticoides, Trichurk rrichium, Taenia, and, most probably, Dicmcoelium dendriricum , were found. These findings allow several conclusions on the epidemiology of parasitic diseases in Central Europe 2000 to 5000 years ago.
