RT Journal T1 Etiologie et prophylaxie de la grippe: Bacille de pfeiffer virus, filtrant grippal. JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1929 FD June 22 VO 92 IS 25 SP 2126 OP 2126 DO 10.1001/jama.1929.02700510056036 UL http://dx.doi.org/10.1001/jama.1929.02700510056036 AB This readable little book on influenza is devoted chiefly to the bacteriology of the disease. Epidemic history and epidemiology are dealt with sketchily. After a lucid but not overcritical discussion of the possible causal relations of the Pfeiffer bacillus, of B. pneumosintes and of filtrable viruses, the author reaches the reasonable conclusion that the etiology of influenza is still an open question. Familiar and readily accessible articles furnish the material on which the book is based.
