EXPERIMENTAL STUDIES OF THE NASOPHARYNGEAL SECRETIONS FROM INFLUENZA XXXX : III. STUDIES OF THE CONCURRENT INFECTIONS.

@entity1 @entity95 @entity281 @entity683 @entity204
1. Concurrent @entity281 in the experiments described may be regarded as of accidental nature and are not causally related to the typical effects induced in @entity95 by a material wholly free from ordinary bacteria. 2. The influenzal agent exerts an effect on the pulmonary tissue which encourages the invasion of the lung and subsequent multiplication there of ordinary bacteria, such as the pneumococcus, streptococcus, and Bacillus pfeifferi. 3. A similarity is believed to exist between the conditions under which concurrent @entity281 arose in the inoculated @entity95 and those which seem to favor the occurrence of concurrent @entity281 during @entity683 in @entity1 . In no instance did @entity204 occur in the @entity95 as a result of the uncomplicated effects of the influenzal agent alone. When @entity204 occurred in any of the inoculated animals concurrent infection of the lungs by ordinary bacteria was present. The microorganisms most commonly met with under these conditions were Pneumococcus Type IV and atypical Type II, streptococci, and hemoglobinophilic bacilli. Other kinds were encountered less often.
