Total viable cells and lactose non-fermenting cells were counted from animal feedstuffs (n=65). And isolation of Gram negative lactose nonfermenting enterobacteria and antibiotics susceptibility of isolates were performed. 1. The ranges of total viable cells / lactose non fermenting in animal feedstuffs from Korean cattle were counted as 9×10-1×10/1×102-6×10, milking cow as 1×104-2×108/2×102-8×10, pig as 1×104-1×106/2×102-6×104, and chicken as 7×l04-1×109/4×102-1×105 cfu/g, respectively. 2. Among the 214 isolates from feedstuffs, 87 from Chinan(n=23), 66 from Changsu (n=23) and 61 from Mooju(n=19) were isolated. Of these isolates, 60 from pigs (n=19), 51 from milking cows(n=15), 45 from chikens(n=11) and 58 from Korean cattle(20) were isolated. 3. Among the 6 genuses of Gram negative lactose nonfermenting enterobacili, Sal-monella sp, Y pseudotuberculosis, Ent agglomerans and Sal choleraesuis were frequently encountered. 4. A majority of isolates were sensitive to 19 antibiotics, singly or in combination. These isoates were completely susceptible to Cp, Gm, Imp and Pi, 93% to Ak and To, 73% to Cax and Ts, 66% to Cit and Tim, 46-53% to Caz, Cf and Cz, 33-40% to Am, Azt, Cfz and Ti, and 6% to Cfx, in order, but not susceptible to Crm. 5. Among the antibiotic resistant strains, a total of 23 resistant patterns was noted, and of these Crm 40(18.7%), Am Cf Cfx Cfz Crm Ti 27(12.6%), each of Azt Ctx Crm and Azt Cax Caz Cft Cfx Crm 22(10.3%) were frequently encountered.

Fugi are eukaryotic, nonphotosynthetic, filamentous or unicellular organisms, most of which grow on nonliving materials as saphrophytes. The majority are therefore opportunistic pathogens and predisposing factors often contribute to the establishment of fungal infection. These include an alteration in the normal flora of the host by prolonged administration of antibiotics, immunosup-pression, concurrent infections, damage to the skin or mucous membranes, constantly moist areas of skin or the exposure to a large infective dose, and as with fungal spores. Fungi may cause a variety of diseases which may be due directly to fungal invasion of tissue or more often to the ingestion of toxins produces by fungi in growing, standing or stored grains and other animals feeds. In this experiment, contaminated fugi were isolated and identified from animal feedstuffs such as Korean cattle, milking cows, pigs and chickens. Twelve genues were isolated from animal feeds, they are 9 from Korean cattle and milking cows feeds, 6 from pigs feeds, and 10 from chickens feeds. Among them, most frequently encountered species was Yeast(56 strains), followed by Fusarium sp(41 strains), Aspergillus sp(20 strains), each of Microsporum sp and Trichophyton sp(17 strains), Penicillium sp(12 strains), in order. And also minority was isolated as Candida sp(4 strains), Trichoderma sp(3 strains), each of Epidermophytom sp and Absida sp(2 strains), and each of Sporothrix sp and Maduromyces sp(1 strain). Among the Aspergillus sp 20 isolates, A flavus(5 strains), A nidulans(4 strains), A fumigatus(3 strains), A glucans(3 strains), A niger(3 strains) and A terreus(2 strains) were identified.
