Lee, C.G. | Park, Y.J. (Chonnam National Univ., Kwangju (Korea R.))
Fecal samples from beef and dairy calves less than 12-month-old of Chonnam area were examined for coccidial oocysts. The percentages of cattle and coccidian species found were: Eimeria alabamensis, 9.4; E. auburnensis, 12.5; E. bovis, 29.9; E. brasiliensis, 1.5; E. bukidnonensis, 2.1; E. canadensis, 10.4; E. cylindrica, 7.5; E. ellipsoidalis, 11.5; E. pellita, 1.7; E. subspherica, 10.4; E. wyomingensis, 2.9; and E. zuernii, 22.5. Fifty five percent of the fecal samples from 521 calves were positive for oocysts, and clinical coccidiosis was not found in any of these calves. The number of species in positive samples ranged from 1 to 7

1988
Chung, B.G. | Kang, H.J. (Kyongsang National Univ., Chinju (Korea R.). Dept. of Veterinary Medicine)
The present study was carried out to investigate C. jejuni and C. coli in chicken. Also were examined the pathogenicity of the isolates in chicks by experimental inoculation. Thermophilic Campylobacter were isolated from 34 (45.9%) of the 74 specimens, and classified as 21.6 % C. jejuni, and 24.3 % C. coli. In the biotyping of 16 strains of C. jejuni isolates, 37.5 % of the strains were grouped as biotype I, 62.5 % as biotype II. In the case of 18 strains of C. coli isolates, 49.9 % of isolates were grouped as biotype I, 55.6 % as biotype II. In oral inoculation with 10** (4)cfu of Capmylobacter isolates into infant chicks (1 to 3 days-old), 17 days-old and 34 days-old chicks, 32.5 % of the chicks developed diarrhea on day 1, 52.5 % on day 3, 70.0 % on day 5, and 27.5% on day 7, and the peak incidence of diarrhea was reached on day 5. The organisms were found to be discharged in feces one day afterwards. C. jejuni and C. coli strains were detected from the feces in 87.5 % of the chicks on day 5.
