Pathogenicity of Spirilla in the Sputum

Sir,?Will any of your readers kindly throw light on the pathogenicity of spirilla in the sputum and oblige? T have recentlv been getting a series of cases suffering from bronchitis, and sputum examination invariably shows the presence of spirilla (along with other organisms), which are thick, short, and have three to five threads each. I have made myself sure that they are not from gums or oral...

The Etiological Relation of Spirilla (vibrio Fetus) to Bovine Abortion

The isolation in pure culture of a definite morphological entity (vibrio or spirillum) with practically the same biological characters from a series of cases of the same clinical complex (abortion) establishes a presumption in favor of the specific identity of the organisms and also in favor of the inference that such organisms are etiologically related to the diseased condition. This presumpti...

Further Studies upon the Pathogenic Spirilla of the Schuylkill River at Philadelphia

In a former paper* by one of us (A. C. A.) attention was called to the fact that in the water of at least one American river, viz. the Schuylkill, at Philadelphia, pathogenic spiril]a had been detected that possess the majority of the characteristics common to that group of spirilla whose most important member is the spirillum of Asiatic cholera. In the course of the investigation seve~:al ques...

Spirilla Associated with Disease of the Fetal Membranes in Cattle (infectious Abortion)

Spirilla of identical morphological and cultural characters have been isolated in pure culture from the fetuses of fourteen cases of abortion. The condition of the fetus is much the same whether spirilla or the bacilli of abortion are present. This condition is probably due in both cases to interference with the placental circulation. The injurious action of the etiological factor when spirilla...
