The General Infections of the Genitalia of Swine 743

Hydrosalpinx occurs in swine, as in cows. In Fig. 218 

 there is illustrated an interesting instance of extreme bilat- 

 eral hydrosalpinx in a pregnant sow, showing that severe 

 tubal infection may exist at the date of coitus without in- 

 hibiting fertilization and then develop so rapidly that long

of horn, probably embryonic debris ; 3, ovary sectioned, showing small 



cysts ; 4, cystic distension of adherent pavilion ; 5, cystic oviduct. 



before the end of pregnancy the reproductive life of the sow 

 has been permanently closed — unless one believes that the 

 tubal infection was post-coital. 



The gravid uterus of the sow, the embryonic envelopes, 

 and the embryos show essentially all the lesions already de- 

 scribed for the cow, and it is only necessary to point out 

 here certain deviations in type due to fundamental differ- 

 ences in the species. Intra-uterine infection with necrosis 

 of the poles of the embryonic sacs is so nearly universal
