The risk factors of Toxocara can is infestation were assessed among population of patients from the Lublin region. Sera from 151 patients suspected of toxocarosis were tested on the presence of the specific antibodies by ELISA (Biokema-Bordier, Switzerland). Sera from 74 women and 77 men were collected (mean: 24 years; range: 0-74 years). Women sera were found positive in 27 cases (36.5%) and men in 34 cases (44.2%). Positive results were found in the following age groups: young people up to 15 years - 34 positive from 71, people from 16 to 30 years old - 7 from 33, people from 31 to 45 years old - 9 from 24 and people older than 45 years - 11 from 23. Patients suspected of ocular larva migrans were found serologically positive in 37cases from 98. Among patients with eosinophilia 8 positive cases were found from 17 (47.1%). Rural inhabitants were found positive in 41 cases from 73, whereas inhabitants of small towns in 17 cases from 55 and inhabitants of Lublin city (population nearly 400,000) in 3 cases from 23. This relationship was statistically significant (p<0.01). The difference between the group of living in a house (52% positive cases) compared to those living in flats (18% positive cases) was also statistically significant (p<0.001).

Soil chemistry, soil microbial biomass and mineralization rate of organic matter (OM) were estimated on plots, which were set up in Scots pine and Norway spruce forests in southern Poland. The aim of the study was to assess the relations between soil microbial biomass and chemical parameters associated with soil fertility. The size of microbial biomass was found to be significantly correlated with chemical parameters reflecting soil nutritional status (content of base cations, cation exchange capacity, base saturation) and organic matter quality (Corg to macronutrients ratios). In addition, soil microbial biomass appeared to be strongly correlated with OM mineralization rate. These findings point out a distinct relationship between soil fertility and soil microbial biomass, suggesting that microbial biomass measurements provide a valid estimate of soil quality.
