During the years 1992-1993 terrestrial snails were examined to the infection with larvae of Protostrongylidae family in the South and North of Poland. Using compressor method 2267 terrestrial snails from two areas (Pszczyna and IÅ‚awa) were examined. Collected gastropods belonged to the following species: Arion subfuscus (45 specimens), Bradybaena fruticum (9), Cepaea nemoralis (29), Succinea putris (2147), Zonitoides nitidus (37). Larvae of three species of Protostrongylidae family were found: Elaphostrongylus cervi, Varestrongylus sagittatus and V. capreoli. The highest extensiveness of invasion of Protostrongylidae was noticed in Succinea putris and reached 23,5% in one of plots in the IÅ‚awa Forest District. The highest intensity of infection was found in S. putris and was as follows: E. cervi up to 150 larvae, V. sagittatus up to 41, and V. capreoli up to 132 larvae. Besides Z. nitidus (1 specimen) there were not noticed any larvae of Protostrongylidae in other species of terrestrial snails. Average extensiveness of invasion of Protostrongylidae in 1992 and 1993 amounted to 7,2 and 9,5% in IÅ‚awa, and 13,9 and 9,4% in Pszczyna, respectively. The highest percentage of infested gastropods was noticed in June and July. Similar results were obtained in both biotopes examined

DEVELOPMENT OF THE ELISA KIT FOR THE DETECTION OF HYPODERMA BOVIS ANTIBODIES IN CATTLE. II. SETTING THE BEST TERMS FOR COLLECTING BLOOD SAMPLES FOR THE LABORATORY DIAGNOSIS OF HYPODERMOSIS IN DIFFERENT REGIONS OF POLAND
The experiments were carried out on 285 cows from 10 herds from different regions of Poland. Extensity of the H. bovis invasion in each herd varied from 10 to 86%. The highest extensity appeared in herds from eastern and north-eastern Poland and the lowest in herds from southern and central regions of the country. Seroconversion of Hypoderma bovis antibodies was calculated for animals in which warbles were detected by clinical examination. The highest serum densities were observed in herds in March, April and May. The results of these investigations demonstrated that the best term for collecting blood samples to examine cattle for hypodermosis is the winter-spring season
