| bacteriocin-like antagonism in yersinia enterocolitica. | a total of 121 yersinia enterocolitica o3 isolates from patients with gastroenteritis and 37 y. enterocolitica reference strains with different o antigens were tested for bacteriocine production and sensitivity. by using cross-streaking method strains belonging to serogroups of o5; o7,8; o7,13; o11; o11,23; o13,27; o17; o19,8 and o34 produced bacteriocin-like substances. none of the y. enterocolitica o3 strains produced bacteriocin-like material and most of them were uniformly sensitive against ... | 1992 | 1284897 |
| in vivo neutralization of tumor necrosis factor-alpha and interferon-gamma abrogates resistance to yersinia enterocolitica infection in mice. | cytokines are important mediators of the inflammatory host response against infectious agents. in this study, the role of tumor necrosis factor-alpha (tnf-alpha) and interferon-gamma (ifn-gamma) in the elimination of a primary infection with highly virulent yersinia enterocolitica serotype 0:8 strain wa-p has been investigated in c57bl/6 mice. the injection of anti-tnf-alpha or anti-ifn-gamma antibodies ("serotherapy") prior to the intravenous challenge of a sublethal dose of y. enterocolitica c ... | 1992 | 1287419 |
| [biological characteristics of tumor growth delay in human nasopharyngeal carcinoma xenograft (npc-837) after irradiation]. | tumor growth and cell cycle of human nasopharyngeal carcinoma xenograft in nude mice (npc-837) after irradiation were studied. after cobalt-60 irradiation of 5.0gy, 7.5gy, 10gy, 15gy and 20gy, the tumor volume was reduced to 80, 70, 50, 35 and 10 percent of the control, respectively. however, the tumors began to grow again. the time (in days) the tumors took to reach the volume of the control was radiation dose-dependent. with 20 gy irradiation the tumor volume was kept at 10% of the control lev ... | 1992 | 1291288 |
| influence of a 70 kilobase virulence plasmid on the ability of yersinia enterocolitica to survive phagocytosis in vitro. | during the course of infection, yersinia enterocolitica invades tissues where macrophages and polymorphonuclear leucocytes (pmns) constitute the first line of defence. as expression of virulence in y. enterocolitica is governed in part by a c. 70 kilobase virulence plasmid (pyv), we investigated the influence of this plasmid on the interaction between y. enterocolitica and phagocytes in vitro. the results showed that, irrespective of plasmid-carriage, yersiniae survived phagocytosis by macrophag ... | 1992 | 1291840 |
