A total of 958 samples of raw fish, fish products and "frutti di mare" were tested for staphylococci. Among 153 strains isolated and subjected to identification the most frequently present were: S. aureus, S. warneri, S. hominis and S. sciuri. These species stated for 46.4; 20.9; 7.2 and 5.2 percent of the total number of identified staphylococci species, respectively. Atypical coagulase-negative S. aureus represented 11.3 percent of identified strains of this species. With coagulase-negative staphylococci taken into account, presence of staphylococci was confirmed in 69.8 percent of the 275 samples tested, while contamination with coagulase-positive staphylococci was confirmed in 24.7 percent of them

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
