Evacuation of atmospheric air from glass tubes by flushing with pure carbon dioxide lowered the content of oxygen to about 0.4 per cent. Three B. fragilis strains and one strain of Fusobacterium mortiferum and of Peptostreptococcus anaerobius were investigated. Bacterial recovery was determined one hour and 24 hours after evacuation of atmospheric air by pure carbon dioxide and pure nitrogen, was compared to bacterial recovery from samples transported with free access to atmospheric air. Evacuation by pure carbon dioxide significantly improved the recovery of one B. fragilis strain after 24 hours of transportation and significantly impaired the recovery of Peptostreptococcus anaerobius after one hour of transportation, while evacuation by pure nitrogen significantly improved the recovery of Peptostreptococcus anaerobius after 24 hours of transportation. In all other cases, however, no statistically significant effect on bacterial recovery was found.","PeriodicalId":75410,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

The growth inhibitory component, formerly separated from the antiviral component of human leukocyte IF by adsorption chromatography on albumin-agarose, is investigated. The properties of the component are compared with the accepted characteristics of IF. The growth inhibition is caused by a small molecule, unstable to pH 2 treatment with HCl, but stable to trichloro-acetic acid (TCA) and to proteolytic enzymes. The isolated growth inhibitor seems to be a dimer of molecular weight (mol wt.)˜2300. It is activated by heat treatment and lacks species specificity. The discrepancies in the properties of the growth inhibitor before before and after separation from IF are discussed.","PeriodicalId":75410,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

However, no direct coagglutination was observed between cell-free supernatants of HSV or HSV-infected cells and sensitized staphylococci. When monolayers or suspended cells infected with the virus were treated with dilutions of specific anti-HSV antiserum followed by non-sensitized staphylococci (indirect method), an \"aureola\" of the bacteria was detected around the cells expressing the viral antigens. A similar picture was observed when infected cells were interacted directly with sensitized staphylococci. Viral antigens were detected already 12 hours post infection, well before the appearance of cytopathic effect.
