The author found out that haematophagic Mallophaga E. stramineus parasitizing on hens can get infected with strain Salmonella gallinarum while feeding on the blood of hens diseased or died of typhoid. From the alimentary canal of Mallophaga 16 bacterial strains were isolated, which in respect of biochemical and serological properties were in most cases identical with strain S. gallinarum used for experimental infection of hens. There was stated no possibility of hens getting infected by transmission of Mallophaga from those died of typhoid on the feathers and healthy or injured skin of hens free from diseases. This kind of infection was not observed even in case of hypoimmunity of the infected hens.
