Prophylaxis. — To prevent takosis it is recommended that 

 when goats are shipped from one part of the country to 

 another that it be done during the summer or late spring, 

 and not in the fall or winter, thus avoiding as far as possible 

 sudden climatic changes. It is also advisable at all times to 

 provide the goats with a storm shelter to which they go 

 voluntarily during a downpour of rain. That the herd should 

 be given proper food and careful attention is obvious. 



Once the disease has made its presence in a flock the separ- 

 ation of the sick and the healthy coupled with a thorough 

 disinfection of the premises are indicated. 



SEPTICEMIC DISEASES OF NEWBORN ANIMALS. 



Dysentery of Sucklings (Dysenteria Neonatorum). — Defini- 

 tion. — This is an acute, gastro-enteritis rarely occurring in 

 animals over one week old. It appears enzootically and is 

 characterized clinically by a profuse diarrhea, great exhaus- 

 tion, and a rapid, fatal course. 



Occurrence. — The disease occurs in calves, lambs, foals, and 

 pigs (rare in dogs and cats) and appears especially in breeding 

 districts at the time of parturition (spring and fall), causing 

 great losses on account of its rapid spread and fatal termina- 

 tion. In some outbreaks every calf or lamb born on the prem- 

 ises becomes infected and dies of the disease in the first few 

 days of its extra-uterine life. 



Etiology. — The Bacillus coli communis or some of its varie- 

 ties. Feeding experiments and rectal injections of colon 

 bacilli obtained from victims of the disease reproduce it in 

 calves of susceptible age. It is possible that other bacteria 

 may be contributory causes. The Bacillus enteriditis of 

 Gartner and the Bacillus pyocyaneus of Poels are accused. 



Natural Infection. — Once introduced into a barn the infec- 

 tion remains there with remarkable tenacity, causing year
