These two strains were sensitive in vitro to the bacteriostatic effect of LF + IgG. A kinetic study of the in vivo establishment of E. coli S17 was followed in axenic mice associated with that strain. Seven hours after inoculation, no difference was observed in the faecal level of E. coli between control mice and mice fed the same diet supplemented with LF + IgG. An in vivo study was also carried out in human newborns receiving either maternized milk (Nursie) or the same milk supplemented with LF + IgG during the first 48 h of life. One group of babies was inoculated at birth with E. coli EMO1, while another was not. Between the ages of 1 and 5 days, the kinetics of establishment of the E. coli strains spontaneously found in the digestive tract of non-inoculated babies was not significantly different between the group which received milk supplemented with LF + IgG and that which did not. This result was confirmed in infants inoculated with E. coli EMO1. Likewise, the faecal levels of E. coli EMO1 were similar in the supplemented and non-supplemented babies, and, already from day 1, the population level was high and only slight individual variations between babies of the same group were observed. These findings show that the in vitro bacteriostatic effect of LF + IgG on the growth of E. coli strains is not found in vivo.","PeriodicalId":7904,"journal":{"name":"Annales de microbiologie","volume":"134B 3","pages":"429-41"},"PeriodicalIF":0.0,"publicationDate":"1983-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17432076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Fusobacterium necrophorum isolated from a hepatic abscess and from mastitic udder secretions in a heifer.","authors":"T Shinjo","doi":"","DOIUrl":"","url":null,"abstract":"Strains of Fusobacterium necrophorum were isolated from secretions of an udder affected with mastitis (4 strains), an adjacent unaffected udder (3 strains), a superficial inguinal lymph node (2 strains) and a liver abscess (4 strains). These 13 strains were examined bacteriologically together with three known strains: F. necrophorum VPI-2891 and VPI-6161, and Sphaerophorus necrophorus (F. necrophorum) N-167. All strains produced butyric acid from glucose and propionic acid from lactic acid, were positive for the indole reaction, failed to hydrolyse esculin, caused beta-haemolysis and showed sensitivity to penicillin (500 U/ml). They were divided roughly into two groups on the basis of differences in their properties as described below. Six strains belonged to one group and ten strains to the other: the former agglutinated chick red blood cells, formed colonies of type A of Fiévez, were long rods, showed turbid growth in liquid medium and were highly pathogenic for mice; the latter strains, consisting of short bacilli and forming colonies of type B, had no or weak haemagglutinin, showed, in liquid medium, sedimentary growth with a clear supernatant and were not fatal to mice. The 4 strains isolated from the hepatic abscess as well as the F. necrophorum strain VPI-2891 and the Sphaerophorus necrophorus strain N-167 were classified into biovar A. The 9 strains isolated from udder and lymph node, as well as the F. necrophorum strain VPI-6161, were classified into biovar B.","PeriodicalId":7904,"journal":{"name":"Annales de microbiologie","volume":"134B 3","pages":"401-9"},"PeriodicalIF":0.0,"publicationDate":"1983-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17432073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
