BACTERIOLOGY IN A NUTSHELL.

 Dysentery.

 Infection. 



recently, under which circumstance the reac- 

 tion may occur without such evidence of the 

 onset of a new attack. 



Cholera is caused by Koch's comma bacil- 

 kts. Dysentery, a somewhat similar disease, :s 

 caused by the bacillus dysenteriae — ^both of 

 these diseases are contracted through the same 

 sources as typhoid fever is contracted, and the 

 same watchfulness against its spread must be 

 rigidly carried out; also the same precautions 

 as to personal cleanliness and neatness with 

 regard to the nurse, patient, and patient's room. 

 Be especially careful to let the pure air and 

 sunshine have free access at all times, and 

 remember the danger from impure water. 

 Epidemics of cholera from that source are not 

 common here. An epidemic occurred in Ham- 

 burg, Germany, in the months of August and 

 September, 1892, when nearly nine thousand 

 deaths were reported during the two months. 

 The epidemic was believed to be due to the 

 infection of the river from which that city ob- 

 tains its water supply. Gipsies had camped on 

 the river banks, and as they had a case of 

 cholera in their midst, the trouble was thought 

 to have arisen from that source. 



Diphtheria. The bacillus diphtherise, the 

 micro-organism of diphtheria, can be taken into 

 the system in food. It may also be communi- 

 cated from the sick to the well directly from the
