Prevention. ]^93 



The conjunctivitis may be treated with washes of mild 

 collyrimns, such as boracic acid or creolin solution, later astrin- 

 gent washes may be applied (0.5 to 1% tannin, or sulphate of 

 zinc solution, collyrium adstringens luteuni). In the presence 

 of a chemotic swelling of the conjunctiva, and keratitis, moist 

 warm applications are advantageous. If the iris is also affected 

 a 1% atropine solution may be dropped into the eye. 



Swellings of the skin are benelited by rubbing with alcohol 

 containing oil of turpentine. Acetate of lead (5%) or Burow's 

 solution, with the addition of camphor, may also be applied 

 to this form of affection. 



In the convalescing stage the animals require good nourish- 

 ment and rest, although moderate exercise in favorable weather 

 is rather profitable than injurious. Animals should be used 

 for work only when all sjnnptoms of the disease have disap- 

 peared, and after they regain their former strength. 



The symptomatic treatment is similar to that followed in the pneumonia or 

 pleurisy and enteritis resulting from other causes; see accordingly their respective 

 chapters in the second volume. 



Serum Treatment. Lignieres recommends his polyvalent Pas- 

 teurella serum for the treatment of infiiienza (see page 86). In acute 

 cases of the catarrhal form of iiiflueuza, in the presence of a fever 

 (40.5 to 41°), he injects 40 to 60 cc. of the serum intravenously, where- 

 upon the fever is reduced, the patient becomes brighter, and recovers 

 inside of a few days. In subacute cases (39 to 39.5°), the temperature 

 usually rises somewhat after the injection, but drops after 10 to 12 

 hours, to normal. He also observed improvement in the presence of 

 pneumonia, when the serum was administered within the first 24 to 

 36 hours, while later treatment promises little result, because of the 

 associated streptococcus infection. Believing that the inflammatory 

 processes may also be caused or aggravated by streptococci, Joly recom- 

 mends the subcutaneous injection of anti-streptococcus serum (25 to 30 

 cc. daily). 



Prevention. Healthy horses should be separated from 

 affected animals, as well as from attendants and utensils that 

 come in contact with diseased, animals or with their secretions. 

 It is advisable to isolate a newly acquired horse for two weeks 

 for observation, and it should be placed among the other horses 

 only after that period. This applies particularly to regions 

 in which the disease is prevalent. 



If the disease has already appeared the affected animals 

 should first of all be separated, and their stalls, as w^ell as the 

 neighboring stalls, should be thoroughly disinfected. As in 

 the first place the immediate neighl)oring animals are under 

 suspicion of becoming affected, they, as well as all animals 

 showing an elevated temperature or catarrhal symptoms, 

 should be segregated in different isolated places. At the same 

 time the healthy animals which liave no fever should be kept 

 out of doors, as far as place and weather conditions permit, 

 or in places which are free from the infection. They should 

 be divided in groups, and only animals which are entirely free
