It was also shown that animals may become infected through the faeces of a flea which has been fed on plague-infected rats.
Discharges - vomited matters, sputa, urine and faeces - are possible media by which plague is spread from person to person.
Lower down in the bowel these compounds are converted into ferrous sulphide and tannate, and are eliminated with the faeces, turning them black.
Unchewed oats pass out in the faeces uninjured, so that they are capable of germination, and are of less than no value to a horse.
The innermost, the coprodaeum, is an oval dilatation of the end of the rectum, and attains its greatest size in those birds whose faeces are very fluid; it serves entirely as the temporary receptacle of the faeces and the urine.
