INFLAMMATION- AND SUPPURATION 



found in the muco-purulent secretion by staining films with 

 ^^^^^^_ weak (1 : 10) carbol- 



fuchsin, and is often to 

 be seen in the interior 

 of leucocytes (Fig. 62). 

 Another organism ex- 

 ceedingly like the prev- 

 ious, apparently differing 

 from it only in the rather 

 wider conditions of 

 growth, is Muller's bacil- 

 lus. It has been culti- 

 vated by^him in a con- 

 siderable proportion of 

 cases of trachoma, but 

 its relation to this con-

acute conjunctivitis, showing Koch-Weeks dispute. Another bacil- 



bacilli, chiefly contained within a leucocyte, lus which is now well 



(From a preparation by Dr. Inglis Pollock.) rec ognised is the diplo- 



bacillus of conjunctivitis 



first described by Morax. It is especially common in the more 

 subacute cases of conjunctivitis. Eyre found it in 2 '5 per cent 

 of all cases of conjunc- 

 tivitis. Its cultural char- 

 acters are given below. 

 The xerosis bacillus, 

 which is a small diph- 

 theroid organism (Fig. 

 123), has been found in r 



xerosis of the conjunc- 

 tiva, in follicular con- 

 junctivitis, and in other 

 conditions ; it appears 

 to occur sometimes also 

 in the normal conjunc- 

 tiva. It is doubtful 

 whether it has any 

 pathogenic action of im- 

 portance. Acute con- 

 junctivitis is also pro 

 duced by the pneu mo- 

 coccus, epidemics of the 

 disease being sometimes due to this organism, and also by
