Lactobacillus strains were isolated from volunteer's feces, including from newly-born infants and adults in their 20's, by using differential MRS-BPB plates. Total 56 presumptive Lactobacillus strains were isolated and the bacteriocin productions by the isolates were examined by agar diffusion method. Six bacteriocin-producing strains were confirmed. Among them, two isolates, HU-1 and H22-3, showed the most outstanding antimicrobial activities, which were not affected by pH adjustments or catalase treatments of culture. HU-1 was originated from a two-years old boy and H22-3 was originated from a newly-born infant. HU-1 and H22-3 had the same morphology(short rod) when examined by scanning electron microscope, and the same biochemical traits including growth temperature range, salt tolerance and sugar-fermenting abilities. But the growth-inhibition spectrum and plasmid profiles of HU-1 and H22-3 were different. Both strains inhibited the growth of various Gram (+) microorganisms including Listeria monocytogenes. Micrococcus luteus, and Staphylococcus aureus in addition to many species of lactic acid bacteria, indicating the production of broad-spectrum bacteriocins. Bacteriocins produced by HU-1 and H22-3 were stable up to 90℃, 15 min heat treatments. Their activities were not affected by pepsin or trypsin treatments but destroyed by proteinaseK or pronase treatments.

The genus of Bacteroides has been isolated from vertebrate animal feces. Bacteroides sp. KGMB 02408 was isolated from fecal samples obtained from a healthy Korean. The wholegenome sequence of Bacteroides sp. KGMB 02408 was analyzed using the PacBio Sequel platform. The genome comprises a 5,771,427 bp chromosome with a G + C content of 39.50%, 5,005 total genes, 18 rRNA genes, and 74 tRNA genes. Furthermore, we found that strain KGMB 02408 had some genes for oxidoreductases and menaquinone biosynthesis in its genome based on the result of genome analysis.

The genus of Olsenella has been isolated from vertebrate animal mouth, rumen, and feces. Olsenella sp. KGMB 04489 was isolated from fecal samples obtained from a healthy Korean. The whole-genome sequence of Olsenella sp. KGMB 04489 was analyzed using the PacBio Sequel platform. The genome comprises a 2,108,034 bp chromosome with a G + C content of 65.50%, 1,838 total genes, 13 rRNA genes, and 52 tRNA genes. Also, we found that strain KGMB 04489 had some genes for hydrolysis enzymes, and antibiotic biosynthesis and resistance in its genome based on the result of genome analysis.

As the growth factor of lactic acid bacteria, LD (trehalose) was isolated from Lentinus edode5 by using silica gel column chromatography. LD induced the growth of Bifidobacteria breve and Lactobacillus brevis, which were isolated from human feces. LD selectively induced the growth of lactic acid bacteria among total microflora. When total intestinal microflora were cultured in the medium containing LD, it stimulated the growth of lactic acid bacteria and inhibited harmful enzymes, ${\beta}$-glucosidase, ${\beta}$-glucuronidase, and tryptophanase, of intestinal bacteria. LM, which was a monosaccharide from L. edooles, induced the growth of lactic acid bacteria but it seems to be invaluable in vivo. LH isolated from L. edodes by Sephadex G-100 column chromatography was not effective for the growth of lactic acid bacteria.

The cells of Lactobacillus plantarum MY4 isolated from the human feces were treated for 24 h in artificial bile after incubation for 2 h in artificial gastric juice and final number of the strain was reached to around $3.1{\times}10^8$ CFU/ml. In test of API ZYM kit, ${\beta}$-glucuronidase or ${\beta}$-glucosidase were not produced by L. plantarum MY4. However, ${\beta}$-galactosidase were weakly produced by it, which they would be alleviated the lactose intolerance. L. plantarum MY4 were resistant to antibiotics such as nisin, tetracycline, streptomycin, rifamycin, doxycycline, roxithromycin, chloramphenicol, nystatin, erythromycin, ciprofloxacin and gentamycin. L. plantarum MY4 was affected by alcohol concentration up to 8%, but more than 16%, their growth was not affected significantly. L. plantarum MY4 was shown to inhibit the growth of Listeria monocytogenes ATCC 19111 completely within 24 h of incubation, which indicates its bactericidal nature. Thus, L plantarum MY4 show promise as a probiotic strain because of its characteristics.

This study was aimed to screen edible herbs which control the composition of intestinal microflora. With in vitro experiments, we screened the water or ethanol extracts of about 60 edible herbs and wild plants in terms of the inhibition activity on the growth of the harmful Clostridium perfringens and growth promoting activity for the beneficial Bifidobacteria. The water extracts of mugwort and small water dropwort inhibited the growth of Cl.perfringens both in agar diffusion method and broth culture. On the other hand, the water extracts of petasites, mugwort, yellow day-lily and bitter cress have shown the promotion effect on the growth of Bifidobacterium longum. In the culture test using human feces as starter, the extracts of the above selected herbs increased the population of Bifidobacteria and Lactobacillus while they reduced the numbers of Cl.perfringens and E.coli.

Campylobacter jejuni has been recognized as one of the causes of human gastroenteritis. The feces of a variety of reservoir animals contain c. jejuni as commensals in the intestinal tracts, and are fundamental source of contamination. The intestinal organisms contaminate carcasses, equipment tools hands of the processing line workers and air of the processing facility. Once the contamination happens in the slaughterhouses or the meat processing facilities, it is very difficult to keep the carcasses free from the infection of c. jejuni. Various disinfectants are effective in minimizing the number of Campylobacter infections in the processing facilities by washing contaminated carcasses, tools, and hands. Direct contact with infected animals has been incriminated in transmission of infection caused by C. jejuni. Freezing, cooling with dry air and gamma irradiation are an effective way for preserving the meat and eliminating the transmission, but broad and enforced studies are needed for the practical use.

A 26-year-old male member of the Australian Defense Force presented with a history of central abdominal pain of 4 weeks duration and peripheral eosinophilia consistent with eosinophilic enteritis. Acute hookworm disease was diagnosed as the cause. Adult worms recovered from feces after therapy with albendazole were morphologically consistent with Ancylostoma ceylanicum. As the patient had been deployed with the Regional Assistance Mission to Solomon Islands for 6 months prior to this presentation, it is very likely that the A. ceylanicum was acquired in Solomon Islands. Until now, it has been assumed that any Ancylostoma spp. recovered from humans in Solomon Islands is A. duodenale. However, this case demonstrates that human hookworm infection acquired in the Solomon Islands could be caused by A. ceylanicum.

Increasing presence of wild boar around cities and suburban areas is a growing concern with respect to agronomy, environmental ecology, and public safety. In this study, antibiotic resistance profiles of Escherichia (E.) coli isolated from wild boar and domestic pig fecal samples were compared. Eighty E. coli samples were isolated from wild boars. Resistance of the bacteria to 14 common antimicrobial agents used in human and veterinary medicine was evaluated. Ninety-five E. coli isolates from domestic pig farms were used for comparison. Common and distinct antibiotic resistance patterns were observed when comparing wild boar and domestic pig isolates, indicating that wild boars may significantly influence environmental microbiology.
