Induction of Streptomycin Resistance in Sensitive Hemophilus Influenzae by Extracts Containing Desoxyribonucleic Acid from Resistant Hemophilus Influenzae
Resistance to streptomycin, of a degree exceeding 1000 microg. per ml., has been induced in sensitive strains of Hemophilus influenzae by exposure for 10 minutes to desoxyribonucleic acid-containing extracts isolated from a strain of type b Hemophilus influenzae which had emerged resistant to 1000 microg. of streptomycin per ml. DNA is essential for the process which brings out this change; the...

SUMMARY Thirteen patients with Haemophilus influenzae type b pneumonia are reported to emphasise the clinical, radiographic, and therapeutic aspects of this illness. All but one patient was tnder 21 years of age. The presenting complaint was a variable duration of upper respiratory infection and fever in most cases. One-third of patients had radiographic evidence of pleural involvement ; one-th...
متن کاملThe Microbic Dissociation of Hemophilus Influenzae *
Dissociation in both pathogenic and non-pathogenic bacterial species has long attracted attention, both in this country and abroad, and, as a result, a voluminous literature on the subject has been accumulating. Since the work of Arkwright' and of deKruif7 in I921, dissociational variations in the properties within a bacterial species have been studied in a more or less systematic manner so tha...
متن کاملStudies on Transformations of Hemophilus influenzae
The sedimentation and diffusion coefficients have been determined for Hemophilus influenzae transforming activity and DNA using P(32)-labeled DNA. The methods employed the Spinco fixed boundary separation cell for measurements of the sedimentation coefficient and the Northrop-Anson diffusion cell to determine the diffusion coefficient. There was a very close correlation between the amount of DN...
متن کاملStudies on the Nutrition of Hemophilus Influenzae
The metabolic activity of H. influenzae can be followed quantitatively by measurement of the nitrite produced in a medium containing 0.2 per cent potassium or sodium nitrate. When X-factor, or hemin, and other specific substances required for the optimum growth of H. influenzae, are present in excess, the nitrite produced by this organism is quantitatively related to the concentration of V-fact...
