Myelopoiesis in experimentally contaminated specific-pathogen-free and germfree mice during oral administration of polymyxin.
Oral administration of polymyxin to specific-pathogen-free C3H/Law mice which with previously contaminated with gram-negative bacteria resulted in complete suppression of cecal gram-negative bacteria. Suppression of cecal gram-negative bacteria was accompanied by reduction of the cecal endotoxin concentration from 10 to 1 microgram/g of cecal content as measured with a microtechnique for the Li...
متن کاملSodium transport across the caecal and colonic epithelium of germfree and specific-pathogen free rats.
It was assumed that the enlarged caecum and the accumulation of semiliquid contents in germfree rats is accompanied by changes in sodium absorption. Transepithelial sodium fluxes were studied under Ussing chamber conditions across epithelial sheets of the caecum and colon of germfree (GF) and specific-pathogen free (SPF) rats. Net sodium transport was highest in the proximal colon and in the pr...
متن کاملSalmonellosis in orally infected specific pathogen-free C57B1 mice.
Specific pathogen-free C57B1 mice are 100 to 1,000 times as sensitive as CD-1 mice to intravenous or oral challenge by Salmonella enteritidis or S. gallinarum. Resistance to infection by S. pullorum was unaffected. Growth of Listeria monocytogenes and Mycobacterium bovis (BCG) in intravenously infected C57B1 mice was similar to that seen in CD-1 mice. Quantitative counts of viable S. enteritidi...
متن کاملDetermination Growth Parameters in Different Popullation of Specific Pathogen Free (SPF)Rainbow TroutBrood Stocksnc(orhynchus mykiss)
This study aimed to compare growth indices and production of rainbow trout breeders (Oncorhynchus mykiss) without any specific pathogens in various populations at the Fishery Research Center of Coldwater-Tonekabon. The project's implementation included collecting Pre-breeders were done in selected rainbow trout breeding centers (based on the approval of the Iranian Fisheries Organization and th...
متن کاملImmunogenicity of commercial, formaldehyde and binary ethylenimine inactivated Newcastle disease virus vaccines in specific pathogen free chickens
Newcastle disease (ND) is one of the most important diseases that affect birds; the epizootic nature of the disease has caused severe economic losses in the poultry industry worldwide. In this experiment ND virus (NDV) was inactivated by two different chemicals binary ethylenimine (BEI) and formaldehyde. Formaldehyde was used at 0.1%, while BEI was used at concentrations of 1 to 4 mM. NDV inact...
