THE COLLECTION AND EXAMINATION OF PUS I05 



and suppurative and septicaemic or pyaemic processes connected 

 with the puerperium. 



In general infections which are due to streptococci the use of 

 antistreptococcic serum is indicated, and may offer the only hope 

 for the patient. 



The pneumococcus often produces suppuration in connection with 

 the respiratory system, especially empyema. It also causes many 

 cases of suppurative otitis media and meningitis. 



The bacillus of typhoid fever sometimes causes abscesses in con- 

 nection with the bones after (sometimes long after) typhoid fever. 

 It has been found in other suppurative conditions, e.g., empyema. 



The tubercle bacillus gives rise to "cold abscesses," usually in 

 connection with bone. The suppuration which occurs in the walls 

 of phthisical vomicae is due to other bacteria, chiefly streptococci 

 and staphylococci. The pus in true tuberculous abscesses is thin 

 and watery, like milk and water, and often contains small caseous 

 masses. The cells are usually mostly lymphocytes. In most 

 cases it is perfectly easy to find tubercle bacilli in this pus if it is 

 examined when the abscess is first opened, whereas afterwards 

 none may be found after a very long and painstaking search. 



The bacillus of glanders only causes suppuration in the specific 

 lesions of the disease when these run an acute course. 



The B. coli communis is the chief cause of suppuration occurring 

 in connection with the abdominal viscera, especially of peritonitis 

 due to perforation of the intestine and appendicitis. It frequently 

 attacks the urinary passages, causing cystitis, etc. 



The B. pyocyaneus causes blue pus, usually in connection with 

 the skin or subcutaneous tissues. 



The fungus of actinomycosis has been dealt with already. 



THE BACTERIOLOGICAL EXAMINATION OF THE 

 MOUTH AND FAUCES 



The method of examination of the morbid products of the mouth 

 and fauces in diphtheria has been explained in full, and the 

 methods which are used in other conditions are similar in nature. 

 The more important of these allied conditions are : 

 Simple angina and follicular tonsillitis. 

 Vincent's angina. 

 Scarlatinal angina. 

 Thrush. 

 Syphilitic angina.
