Pathogenic Microbes in the Static Condition. 49 



harvesting, in the storehouses of fodders by the air 

 of infected stables or barns, or from direct contact 

 with sick animals. 



MM. Galtier and Violet attribute to the fodder the 

 development of the typhoid affections of the horse. 



Foods of animal origin are sometimes bearers of 

 pathogenic germs. This is the case when they come 

 from subjects suffering from diseases caused by these 

 germs. The flesh and all the tissues of animals dead 

 from charbon contain the bacteridium. 



Dwellings and vehicles. — Places which have been oc- 

 cupied by animals affected with contagious diseases, and 

 vehicles (wagons, etc.) which have been used in their 

 transportation are most frequently infected by specific 

 germs. These are deposited upon the floor, walls 

 and ceilings of houses and upon the mangers, racks, 

 etc., either by the air or directly with the secretions or 

 excretions of the sick. The transmission of microbic 

 diseases through the intermediation of dwellings is 

 therefore in every way possible. 



Various articles and utensils. — All the articles and 

 utensils which are found in places occupied by diseased 

 animals or which have been employed in the service 

 of the latter — harness, blankets, grooming instru- 

 ments, sponges, brushes, curry-combs, etc., litter and 

 manure — may become bearers of pathogenic germs 

 which have been derived from these animals. 



Healthy organism. — The bodies of animals in health 

 are always bearers of microbes; but the latter are 

 most frequiently of no importance from our present 

 point of view. "We already know that the ubiquitous 

 pathogenic germs — those of suppuration and of septic
