Role of Tumor Necrosis Factor Alpha in Gnotobiotic Mice Infected with an Escherichia coli O157:H7 Strain
ABSTRACT Gnotobiotic mice inoculated with an enterohemorrhagicEscherichia coli (EHEC) O157:H7 strain developed a flaccid paresis, usually culminating in death. The bacteria colonized feces at 109 toExpand

C-terminal domain of human CAP18 antimicrobial peptide induces apoptosis in oral squamous cell carcinoma SAS-H1 cells.
Mammalian myeloid and epithelial cells express many antimicrobiotic peptides that contribute to innate host defense against invading microbes. In the present study, a 27-mer peptide of the C-terminalExpand

Specific inhibition of adherence of an oral strain of Bacteroides gingivalis 381 to epithelial cells by monoclonal antibodies against the bacterial fimbriae.
Monoclonal antibodies against purified fimbriae from this organism blocked its adherence to buccal epithelial cells. Three clones of monoclonal antibodies against these fimbriae were selected forExpand

The gene for component-II of botulinum C2 toxin.
The gene encoding component-II of the Clostridium botulinum C2 toxin was cloned from the chromosomal DNA of C. botulinum type C strain (C)-203U28, and the nucleotide sequence was determined. The geneExpand

Gene arrangement in the upstream region of Clostridium botulinum type E and Clostridium butyricum BL6340 progenitor toxin genes is different from that of other types.
The cluster of genes encoding the botulinum progenitor toxin and the upstream region including p21 and p47 were divided into three different gene arrangements (class I-III). To determine the geneExpand

Epidemiological study on periodontal diseases and some other dental disorders in dogs.
The prevalence of dental disorders in dogs was studied by applying index systems for human with some modifications. A total of 251 mongrel dogs including 143 stray dogs kept in the Animal ProtectionExpand

Decreased lipopolysaccharide content and enhanced susceptibility of leptospiras to serum leptospiricidal action and phagocytosis after treatment with diphenylamine.
Growth of leptospiras in the presence of diphenylamine (DPA) caused a decrease in the content of leptospiral lipopolysaccharide (LPS). In association with this decrease of LPS, leptospiras becameExpand

Biological activities of leptospiral lipopolysaccharide.
Lipopolysaccharide extracted with phenol-water from Leptospira interrogans serovar copenhageni strain Shibaura (L-LPS) showed various biological activities. In lethality for mice, L-LPS was activeExpand

Phagocytosis as a defense mechanism against infection with leptospiras.
The role of macrophages in host defense was studied in vivo and in vitro. The intravenous administration of silica, an agent reported to selectively inactivate macrophages, increased the sensitivityExpand
