| seroepidemiological studies with campylobacter fetus. | 324 sera from unselected male and 581 sera from female patients as well as 268 sera from prostitutes were studied for antibodies against campylobacter fetus using the complement fixation test. antigen was campylobacter fetus subspecies intestinalis. 3.9% of the sera showed low but relevant antibody titers. statistically significant differences don't exist between the three population investigated. serological cross reactions could not be observed using salmonella typhimurium, shigella flexneri, ... | 1981 | 7036594 |
| [use of live flexner 2a 516m dysentery vaccine for the immunotherapy of acute and chronic dysentery]. | live dysentery vaccine prepared from sh. flexneri 2a 516 m, a spontaneous mutant, was used for the treatment of 153 patients with acute and chronic dysentery. a single oral administration in a dose of 25 x 10(9) live microbial cells and 2 oral administrations in doses of 25 x 10(9) and 50 x 10(9) live microbial cells did not induce the clinical aggravation of the disease, greatly reduced the time of the reparation of the intestinal mucosa and reduced the frequency and duration of excretion of th ... | 1981 | 7036601 |
| [increased effectiveness of antibiotic therapy with adaptogens in dysentery and proteus infection in children]. | the course of the disease and the host immunological reactivity (iga, igm, igg, cphi, igg and igm antibody titers in the hit, blood bactericidic properties) were studied in 258 children aged 0 to 14 year suffering from acute dysentery caused by shigella sonnei and flexneri and enterocolitis of the proteus etiology. 157 patients were treated with monomycin and kanamycin in combination with adaptogens, such as eleuterococcus and echinopanax elatum nakai l. and 101 patients were treated with the an ... | 1982 | 7036851 |

| adherence of shigella flexneri to guinea pig intestinal cells is mediated by a mucosal adhesion. | guinea pig colonic epithelial cells released by treating sections of the colon with solutions containing edta, dithiothreitol, and citrate avidly adhered shigella flexneri bacteria. separation of the intestinal cells from nonbound bacteria was achieved by differential sedimentation on a percoll gradient. adherence of s. flexneri to the colonic cells was ca2+ (1 mm) and time dependent. the ph optimum was ph 6.2, and almost no attachment (less than 5%) was observed at low temperature (4 degrees c) ... | 1982 | 7040246 |

| shigella enterocolitis and acute renal failure. | although acute renal failure secondary to infections is relatively common in adult patients, uremia requiring dialysis has not previously been reported in an adult patient with shigella enterocolitis. our patient, infected with s flexneri, had severe renal failure without any evidence of sepsis, rhabdomyolysis, or the hemolytic-uremic syndrome. antibiotic therapy with trimethoprim-sulfamethoxazole appeared to play a role in his eventual recovery. | 1982 | 7041284 |

| [local immunity in acute dysentery. ii. the content of antibody-forming cells in the large intestine mucosa in acute flexner dysentery in the dynamics of the disease]. | antibody-forming cells were detected in the large intestine of patients with acute flexner's dysentery by means of the modified jerne - nordin method of hemolysis in agar. this method allowed one to determine the classes of immunoglobulins produced by the cells contained in tissue microspecimens obtained by the biopsy of the intestinal mucosa. the maximum amount of antibody-containing cells could be detected on days 7-12 of the disease. the content of antibody-forming cells was shown to depend o ... | 1982 | 7043970 |

| plasmid-mediated invasiveness of "shigella-like" escherichia coli. | invasive escherichia coli is a "shigella-like" microorganism which causes a dysenteric syndrome through invasion of the human colonic epithelium. representative strains of different serotypes were studied in order to determine whether plasmids are involved in their virulence. all invasive e. coli strains, irrespective of serotype, were found to harbour a large plasmid of approximately 140 mdal. spontaneous variants of serotypes o143 and o124 had lost this plasmid and had become avirulent, i.e. c ... | 1982 | 7049041 |
| shigella species from addis ababa: frequency of isolation and in vitro drug sensitivity. | one hundred and five shigella isolates from addis ababa were studied to determine serogroup frequency and in vitro antibacterial drug sensitivity. about 70% of the isolates were shigella flexneri followed by sh. dysenteriae (15%), sh. boydii (10%) and sh. sonnei (5%). all or most of the strains were susceptible to cephalothin, gentamicin, kanamycin, polymyxin b and trimethoprim-sulphamethoxazole. frequencies of susceptibility to ampicillin, carbenicillin and chloramphenicol were, respectively, 7 ... | 1982 | 7057026 |
| antibacterial substance from carica papaya fruit extract. | ripe and unripe carica papaya fruits (epicarp, endocarp, seeds and leaves) were extracted separately and purified. all the extracts except that of leaves produced very significant antibacterial activity on staphylococcus aureus, bacillus cereus, escherichia coli, pseudomonas aeruginosa and shigella flexneri. the mic of the substance was small (0.2-0.3 mg/ml) for gram-positive bacteria and large (1.5-4 mg/ml) for gram-negative bacteria. the substance was bactericidal and showed properties of a pr ... | 1982 | 7097295 |
| high frequency of hla-b27 and reiter's syndrome in navajo indians. | eighteen cases of reiter's syndrome were found in a population of approximately 6,000 navajo indians. the phenotype frequency of hla-b27 in this population was found to be 36%. the area in which these people live is endemic for shigellosis, shigella flexneri being the most common species isolated. presumably the high frequency of hla-b27 and shigella infections account for the high incidence and prevalence of reiter's syndrome in this population. | 1980 | 7205829 |
