Fatty acids rendered immunogenic.

A method allowing the covalent binding of fatty acids to a carrier was developed. The absence of absorbed fatty acids was controlled by HPTLC. Rabbits were immunized with these immunogens. The antibodies obtained were studied by ELISA and were shown to be directed against the fatty acyl chain, whatever its length.

[Amoebae in the water supply: an epidemiological study (author's transl)].

Drinking water samples (836) of various origins have been examined for amoebae. For collector water, half of the samples are contamined without influence of the origin. So, occurrence of amoeba in underground waters is discussed. Filtration and disinfection are generally inefficient. Bottles of drinking water are very often polluted during bottling. International mineral waters of french origin are not so damaged during conditioning operation. Bacteria and amoebae populations are quite independant and can't be indicators one for another. Thermophilic amoebae strains are very rare and any pathogenic amoeba has been found during the study.
