The effect of oral administration of three fungicides namely: Triadimefon, Carbendazim and Captan at low and high doses on body weight gain, food consumption, weight of certain organs and water content of the liver in male rats has been investigated. Significant reduction in body weight gain concomitant with significant loss in food consumption was detected in rats which had received high dosses of triadimefon and carbendazim.

To investigate the epidemiological trait of gastroenteritis of human caused by Campylobacter jejuni, isolation of etiological agent was carried out. Isolated C. jejuni were biotyped and serotyped. A total of 1929 specimens from 438 human, 182 milking cows, 200 cattle, 187 goats, 70 dogs, 426 pigs, 278 chickens, 148 duck, 50 raw milk, 110 chicken meat, 20 duck liver and 50 river water was examined for the presence of C. jejuni and C. coli by direct plating and enrichment techniques. Isolation rates detected in human, animals food and water were as follows : human 0.7 %, ducks 54.7 %, dogs 37.1 %, chickens 33.7 %, goats 26.7 %, cattle 25.5 %, pigs 19.9 % and milking cows 7.7 %. The organism was isolated from 65 % of 20 duck livers and from 20 % of 110 chicken meat. Campylobacter was not recovered from raw milk and river water. The majority of the isolated 201 strains of C. jejuni was classified as biotype I (53.7 %) and Biotype II (36.8 %). 117 strains of C. coli were 59.8 % of biotype I, 40.1 % biotype II. Isolated C. jejuni strains showed 13 different serotype, and serotype 4, 5, 26 and 36 were most frequent. C. coli strains showed 7 different serotype, and serotype 21, 25 and 29 were relatively common

Jamroz, D. | Skorupinska, J. | Wiliczkiewicz, A. | Schleicher, A. | Sobiech, K. (Akademia Rolnicza, Wroclaw (Poland))
Studies on medium heavy layers Astra S kept in cages were conducted. The decrease by 6 percent of laying performance and the increase of feed conversion in layers given the diet with plant concentrate feeds than in those fed the DJ concentrate mixture was stated. The change in a triglyceride concentration and activity of some enzymes in blood of layers with water deprivation was found
