Report documenting the isolation and identification of microorganisms found in the noses, throats, and lower intestines of twenty two dogs. The most frequently observed organisms were E. coli and S. viridans.
Fecal specimens from apparently healthy dogs were inoculated into MK, DK, HeLa, and CP cells. Twenty-six cytopathic agents were isolated in MK, 11 in HeLa, and 4 in CP, but none in DK cells. Neutralization tests indicated that all but one of the viruses were either strains of ECHO type 6 or were closely related to it. Twenty-one of 29 dogs were carrying the virus.
From Introduction: "The present study was initiated to provide data regarding the particulate state of fission products released from uranium heated in air. It was expected that the information gained in this work would be valuable in planning experiments in which animals would be exposed to aerosols of mixed fission products and in determining the feasibility of using the effluent from a fuel specimen melt-down or oxidation in such exposures."
From Abstract: "The importance of interspecies comparison in obtaining parameters for estimating hazards to man is discussed, using cesium metabolism as an example."
From Introduction: "The following report describes an ultramicro procedure using ANSA as reducing agent. The method is a modification of the method of Kaser and Baker (4). Results obtained with this method are compared to results obtained with the procedure of Dryer, Tammes, and Routh (2) adapted for ultamicro analysis (3). The latter method uses N-phenyl-p-phenylenediamine (NPPD) as the reducing agent."
From Introduction: "This report describes the development of an ultramicro modification of the method of Chaney and Marbach which is reliable and remarkably suited to routine analysis in bulk."
