The trend of parasitic diseases among the population of Osjecko-baranjska County during the period 1996-2010--Croatia.

Our manuscript shows infestation of the different population (by age groups, and by sex) with endoparasites and ectoparasites from 1996 till 2010, through seasons (spring, summer, autumn, winter).Parasitological examinations which were done at "Public health Institute" of Osjecko-baranjska county, and which were done at total of 3667 patients, were the methods of direct parasitological diagnostic for proof of parasitic elements in clinical samples, and the methods of indirect parasitological diagnostic, serological examination for proof of antibodies to antigens in the serum of the patients or of the asymptomatic parasite carriers. Development of causers of the diseases (parasites) is depending on the season.

Bee community as a source of energy in the production of food, honey-plants in the ecosystem of Croatian Forests' hunting grounds.

In addition to the process of photosynthesis, the bee community is the main source of energy in food production, honey-plants used by game and people in the hunting grounds ecosystem. It is a well-known fact that thousands of plant species depend on the presence of bee communities (pollination, fertilization). In this paper we studied the presence of the bee community in the hunting grounds of Croatian Forests, and their influence on the number of game (wild pigs), as well as the quality of honey, honey plants in the hunting grounds used by people and game.
