| 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 |

| a comparative study of the activity of cefamandole and other cephalosporins and analysis of the beta-lactamase stability and synergy of cefamandole with aminoglycosides. | the antibacterial activity of cefamandole against 445 clinical isolates was investigated and compared with the activity of other known cephalosporins (cephalothin, cephaloridine, cephalexin, and cefazolin) and of two penicillins (ampicillin and carbenicillin). cefamandole was the most active antibiotic against isolates of citrobacter, enterobacter, and shigella, and its activity against staphylococcus aureus, bacteroides, and some members of the enterobacteriaceae was comparable to that of the o ... | 1978 | 349097 |
| 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 |
| haemolytic-uraemic syndrome complicating shigella dystentery in south indian children. | shigella dysentery caused 65% of all cases of acute renal failure (arf) seen in children treated at the christian medical college hospital, vellore, during the 33 months ending september 1977. in the 40 children with arf secondary to shigella dysentery, haematological findings suggested that they were suffering from the haemolytic-uraemic syndrome, and glomerular hypercellularity and fibrin deposition were present in all 12 patients whose renal histology could be studied. peritoneal dialysis was ... | 1978 | 350345 |

| 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 |
| [conditions and factors determining the etiological structure of dysentery and its changes. report 1. epidemiological theory of etiological selectivity of the main (primary) pathways of infection and their differences in various nosological forms of dysentery]. | the authors present the elaborated and formed epidemiological theory ("conformity theory") according to which the etiological structure of dysentery is determined by the etiological selectivity of the main (primary) waves of transmission of the infection differing in various nosological forms of dysentery. in grigoriev-shiga dysentery the domestic way of the spread of infection plays the main role, in flexner and newcastle dysentery--the water way, and in sonne dysentery--the food way (particula ... | 1978 | 352042 |
