EXAMINATION OF THE HUMAN BODY. 



BACTERIOLOGIC EXAMINATION OF THE ORGANS AND 

 CAVITIES OF THE HUMAN BODY. 



THE body, on account of its constant contact with the sur- 

 rounding air, is necessarily exposed to infection, and we would 

 be likely to find on the skin and in the oral, anal, and nasal 

 cavities the varieties of micro-organisms commonly around us. 

 Through the water and food the body is also contaminated; 

 but some organisms by predilection inhabit the mouth, intes- 

 tine, and other cavities, and form there a flora distinctly their 

 own. 



The Skin, The majority of micro-organisms met with on the 

 skin are non-pathogenic, although underneath the nails and in 

 the hair, pus-forming micro-organisms often occur, producing 

 sometimes serious abscesses. 



In the sweat-glands and the sebaceous glands various organ- 

 isms have been found. The Staphylococcus epidermidis albus 

 of Welch is present normally. 



In foul-smelling perspiration of the feet Rosenbach found 

 Saprogenes No. II., which is pathogenic for rabbits. 



Micrococcus cereus albus and flavus, Diplococcus liquefa- 

 ciens albus and flavus, Staphylococcus pyogenes aureus, and 

 Streptococcus pyogenes are found underneath the nails. 



In eczema, Diplococcus albicans tardus, D. citreus liquefa- 

 ciens, D. flavus liquefaciens, and Ascobacillus citreus. 



In colored sweat, Micrococcus hsematodes, Bacillus pyocya- 

 neus. 



A diplococcus is found in acute pemphigus. 



The lepra bacillus, the tubercle bacillus in lupus, and the 

 typhoid bacillus in the eruption of typhoid fever are a few of 

 the specific germs found on the skin. 



The Conjunctiva. The micrococcus of trachoma, the Koch- 

 Weeks bacillus, considered to be the specific cause of acute 

 catarrhal conjunctivitis, or "pink eye," and the Bacillus xero- 

 sis, are special germs found on the conjunctiva ; the other va- 

 rieties of air- and water-organisms, and those usually present 

 on the skin, are also found.
