Cholera studies. V. Bacteriophage investigations

This study is devoted to a general discussion of the role of bacteriophagy in cholera. The author examines early and late observations, indicating that a new epoch in the history of the subject began in 1927, when large-scale investigations on cholera bacteriophagy were started in India. The main results are set out under the following headings: fixation and inhibition of choleraphages; action of choleraphages on El Tor vibrios; bacteriophage-produced vibrio variations; and the use of choleraphage-produced lysates for vaccination.

Cholera studies. 3. Bacteriology

The morphological characteristics, biochemical properties, and cultural characteristics of V. cholerae are described in great detail in this study. The author also discusses the resistance of the organism to temperature, humidity, sunlight, and various chemicals, as well as the viability of V. cholerae outside the body (in faeces, contaminated material, food, beverages, water, etc.).
