This 140 page monograph begins with a consideration of the importance of infection as a cause of summer diarrhea. Of the 1,816 cases studied, 1,611 were selected for statistical purposes. Clinically, three types of summer diarrhea are recognized, namely, choleriform, dysenteric and mixed. In more than half the cases, the etiologic agent was determined as either Salmonella or Shiga's bacillus. In adults and children over 3 years of age the mortality is practically nil, but in those under 1 year, enteritis from Shigella has a mortality of 45 per cent and that from Salmonella a mortality of 30.7 per cent.
In a separate study of parenteral infection from these groups of organisms, meningitis, osteomyelitis and arthritis were found to be the most frequent. An extensive review of the literature is given. The several studies making up this monograph are summarized and translated into French, English and German.
