164 POULTRY DISEASES 



The following germs have been found as normal 

 inhabitants of the duodenum, or first portion of 

 the intestines, of birds : 



Bacillus mesentericus, Bacillus suhtilis, Bacillus 

 ramosus, Bacillus sereus, Bacillus asterosporus, 

 Bacillus fusiformis, Bacillus coli communis j Strep- 

 tococcus lacticus, Bacillus lactis aerogenes, Bacil- 

 lus prodigiosus, Sarcina aurantiaca, Sarcina lutea, 

 Sarcina ventriculus, Clathodrix asteroides, Micro- 

 coccus rosettaceus, brown, white, and green molds, 

 coral and white yeasts, Micrococcus roseus and 

 Clamy dotl'irix ferrugenes. 



In the third portion of the intestines, or ileum, 

 may be found green and white molds, Cladothrix 

 asteroides, Bacillus cloacw, Bacillus ramosuSj Sar- 

 cina lutea and Sarcina aurantiaca, Staphylococcus 

 pyogenes alhus and citreus, Staphylococcus cereus 

 alhus, Bacillus fluorescens liquefaciens, Micrococ- 

 cus asterosporus, Streptococcus lacticus, Bacillus 

 lactis wrogenes. Bacillus coli communis. Bacillus 

 prodigiosus. Bacillus mesentericus. Bacillus cer- 

 eus. Bacillus megatherium. Bacillus fusiformis. 

 Bacillus suhtilis. 



Practically the same microorganisms are to be 

 found in the cecum. The same may be said of the 

 cloaca, with possibly the addition of the Bacillus 

 wrogenes capsulatus and Staphylococcus pyogenes 

 aureus. 



It must be remembered that the intestinal flora 

 is probably not the same for all birds, as different 

 surroundings or environment, different sources of 

 food, as well as different food and water, play a 

 part in carrying germs to the intestinal tract.
