Genera/ Infections of the Genitalia of Sheep and Goats 735 



Fisher regularly obtained, in cultures from the pustules and 

 abscesses, a pure growth of a staphylococcus. Some individ- 

 uals showed merely a few pustules, which after a short in- 

 terval healed, and the animals showed thereafter an imper- 

 fect immunity. A large percentage of cases did not recover 

 spontaneously and were obstinate to symptomatic handling, 

 such as antiseptics, the opening of the abscesses, etc. They 

 were highly successful, however, in the use of autogenous 

 bacterins. As the work progressed, they used successfully 

 bacterins made by combining cultures procured from vari- 

 ous similar cases. 



The relationship, if any existed, between the disease de- 

 scribed by Stone and Fisher, believed to be due to staphylo- 

 cocci, and the abortion and sterility was not made clear, but 

 they believed, upon apparently excellent grounds, that the 

 interferences with reproduction were basic results of the 

 malady. 



In other instances abortions in goats occur in which the 

 staphylococcus described can not be found, but other bac- 

 teria are present. In some instances, also, the fetus per- 

 ishes and, owing to uterine inertia with cervical induration, 

 retention of the fetus follows. Then prolapse of the cervix 

 ensues, having the same general characters as the cervical 

 prolapse of the ewe already described. 



Since the general principles of controlling genital infec- 

 tions in goats are the same as those advised for cattle and 

 sheep, repetition is unnecessary.
