Rats and Salmonella Group Bacilli

Studies on the Precipitable Substances of Bacilli of the Salmonella Group

Specific precipitable substances rich in carbohydrates, containing very little protein and small amounts of a material apparently of fatty nature, have been prepared from the main serological types of the typhoid-paratyphoid groups. The preparations in their present state of purity do not exhibit very pronounced chemical differences in spite of serological dissimilarity. In this respect the res...

Studies on the Flexner Group of Dysentery Bacilli

1. Volunteers have been immunized with the purified specific antigen of Type V Shigella paradysenteriae (Flexner). The subjects developed a high titer of bacterial agglutinins and mouse-protective antibodies. The agglutinin titer fell moderately after a period of 6 months. The subjects responded fairly well to a small recall dose of the antigen. 2. Two individuals from a group of 10 injected wi...

Divisions of the so Called Flexner Group of Dysentery Bacilli

From these data it is seen that ill defined divisions of the so called Flexner group exist. The divisions do not appear to be sufficiently distinct to warrant the use of separate names. To avoid confusion all mannitol-fermenting dysentery bacilli should be called Bacillus dysenteriae Flexner and the subdivision noted. There are two methods for this division, one by the fermentation of carbohydr...

Pleural Empyema due to Group D Salmonella

Non-typhi Salmonella normally presents as a bacteremia, enterocolitis, and endovascular infection but rarely manifests as pleuropulmonary disease. We present a case of a 66-year-old female with underlying pulmonary pathology, secondary to an extensive smoking history, who presented with a left-sided pleural effusion. The causative agent was identified as being group D Salmonella. Decortication ...
