Strangles, Infectious Rhino-adenitis. 77 



At the onset there is some fever (101° F.), dulness and inap- 

 petence, but these gradually subside, and in favorable cases com- 

 plete recovery has taken place in two or three weeks. 



Bacteriological investigation has detected in the contents of the 

 vesicles, staphylococcus pyogenes aureus, and streptococcus pyo- 

 genes. 



Preiiention is largely secured by a rigid separation of the dis- 

 eased from the healthy. Other obvious precautions would be to 

 exclude those dres.sing the sores from handling other horses until 

 after thorough disinfection of the hands, and to keep the sound 

 animals, during wet seasons, from the damp infecting soils, or 

 when they must work on these, to smear the lower parts of the 

 limbs with antiseptic ointments (tar, carbolic, iodine, mercuric, 

 etc., etc.) 



Treatment with sublimate bandages proves very satisfactory, 

 yet any comparatively non-irritating antiseptic lotion may be used.
