| outbreak of infantile enteritis caused by enterotoxigenic escherichia coli o6.h16. | ten out of 18 babies at risk developed enteritis in an outbreak in a special-care baby unit. salmonella, shigella, and escherichia coli belonging to the traditional infantile enteropathogenic serogroups were not found in faeces from the babies and the staff, and no virus particles were found by electron microscopy. detailed serotyping of e. coli showed that five of the 10 babies with diarrhoea and one of the eight without diarrhoea were excreting e. coli o6.h16. all six isolates of this serotype ... | 1978 | 346609 |

| rifampicin therapy in shigellosis in infancy. | eleven infants aged 1-2 years suffering from shigellosis associated with shigella flexneri type 6 were treated with rifampicin. all were initially treated with antimicrobial drugs to which sh. flexneri was shown to be sensitive, but without effect. rifampicin was effective in curing gastrointestinal symptoms and eradicating the bacilli in all infants in 5 days. the drug was given in a dose of 10-12 mg/kg per day divided into two equal parts, for 7 days. no untoward side effects were observed. ou ... | 1977 | 343724 |
| escherichia coli antibodies in patients with inflammatory bowel disease. | sera from 30 patients with inflammatory bowel disease (ibd) (16 with crohn's disease (cd) and 14 with ulcerative colitis (uc) were assayed for the presence of antibodies against 159 escherichia coli o-antigens and compared with sera from 16 matched control subjects. the majority of patients with ibd had agglutinating antibodies to a higher number of escherichia coli o-antigens and in higher titres than the control group. the number of positive agglutinins was o-33 mean 13.8 in cd, o-26 mean 7.9 ... | 1978 | 344155 |
| humoral bactericidal systems: antibacterial potential of serum from young animals. | the antibacterial potential of fresh serum obtained from young animals during a pre-antibody period of development was assessed against two smooth and two rough strains of gram-negative bacteria. the bactericidal capacity of serum from 3- to 4-week-old guinea pigs and 4- to 5-week-old rabbits was compared with that of serum from adults. serum from young animals was deficient in natural antibodies, and in conventional dilution assays the bactericidal action was unimpressive, especially against th ... | 1978 | 344214 |
| humoral bactericidal systems: nonspecific and specific mechanisms. | bactericidal systems in normal serum from month-old rabbits and guinea pigs were characterized in terms of activity against rough- and smooth-phase species of gram-negative bacteria. killing of the rough strains in the absence of natural antibody required complement and at least one additional nonspecific component exhibiting lability to freezer storage and to heating at 52 degrees c. bactericidal action against the smooth-phase organisms, on the other hand, appeared to require natural antibody ... | 1978 | 344215 |
| comparative clinicopathological and bacteriological studies in schistosomiasis mansoni. | fifty male egyptian inpatients with active colonic mansoniasis were studied clinicopathologically, endoscopically, radiologically and bacteriologically. this was done to find out the pattern of colonic and urinary enterobacteria and serum antisalmonella agglutinins in various stages of mansoniasis. cases are divided into three groups (a, b and c) according to the stage of their hepato-splenomegally. their clinical presentations were dysentery, rectal bleeding, abdominal distension, anaemia, endo ... | 1978 | 348448 |

| shigella sonnei colicine and phage types in east bohemia region. | from november 1972 to the end of 1975, shigella sonnei types implicated in dysentery morbidity in a number of districts of east bohemia region were studied. 301 strains subjected to phage typing and colicine typing were classified into 45 "combined" types. during the study five types prevailed in succession, each for a protracted period of time. four of these types retained, in the great majority of cases, their original high drug sensitivity throughout the period of their prevalence. other type ... | 1978 | 349971 |
| [stimulation of nonspecific resistance in mice with high- and low-molecular fractions of endotoxin on 2 models of shigella infection]. | the capacity of s. paratyphi b endotoxin and its high molecular (hmf) and low molecular (lmf) fractions to stimulate the resistance of mice to shigella infection in intraperitoneal and intranasal challenge was investigated. the hmf developed high activity after the intraperitoneal injection (efficiency index--ei = 2.8). all the preparations were less active on the lung model (ei = 1.6--1.7). materials of this work lead to the conclusion that in studying the phenomenon of nonspecific resistance i ... | 1978 | 350311 |

| invasive escherichia coli. | the present evidence indicates that shigella-like pathogenicity is determined by a multiplacity of genes. although deliberate attempts have been made to confer invasive virulence on e. coli strain k12 by employing classical procedures of recombination with virulent s. flexneri donor strains, they have not yet been successful. while we should, theoretically, be able to achieve this, the practical problem of testing for pathogenicity precludes screening larger numbers of hybrid clones for the acqu ... | 1978 | 351079 |

| diarrhoeal disorders of bacterial origin in jakarta. | during a 21-month period from april 1974 to february 1976, 948 children with gastroenteritis were studied. aetiologic agents were identified in 43% of these patients. isolates were identified as follows: v. cholera el tor, 273 (67%); salmonella enteritidis, 64 (16%); enteropathogenic e. coli, 28 (7%); shigella, 28 (7%); vibrio (nag), 9 (2%): and v. parahaemolyticus, 7,2%). gastroenteritis with dehydration is a serious continuing pediatric problem in jakarta, constituting 30% of admissions to sum ... | 1977 | 351819 |
