Sažetak
Intestinal enterococci (Ie) are well known bacterial indicators of faecal contamination in food as well as in environmental samples. In total 19 soils under the anthropogenic influence in Croatia were analysed: 15 influenced by illegal dumpsites of human solid waste and 4 agricultural soils fertilized with animal manure. Three samples were control soils without the visible anthropogenic influence. The number of Ie was measured after suspension of soil in peptone water and subsequent confirmation on Slanetz Bartley and Bile esculin azide agar. The pH was measured in soil suspension in distilled water. The pH values of soils varied from 4.9 to 9.7. Ie were not detected (˂1 CFU/g) in control soils saved from visible human activities. Ie also were not detected in agricultural soils fertilized with swine or poultry manure. All soils influenced by illegal dumpsites contained the Ie at concentration from 1.3 to 6.2 log CFU per g of wet soil. Ie could be used as indicators of illegal dumps, since they could be leached from the human solid waste by storm water and infiltrated into the underling soil. The traditional use of animal manure as a soil fertilizer has no appreciable influence on the occurrence of Ie. More stringent monitoring and prevention of illegal dumps is needed to avoid the negative human influence on the soil.
