abstract and not coded in Field H-2), etc. , or a natural or unspecified physiological stress. 

 (If the host has had removed from it an organ for any purpose other than to produc ; stress, the 

 condition is coded by Symbol P. ) If the pathology of Field E is specifically of an organ or 

 tissue (coded in Field H-1 or I) and that structure has a second pathological state, use Symbol 

 N or S. If the host has an organ or tissue, other than the organ or tissue site of the pathology 

 (therefore, not coded in Field H-1 or I) which is in a pathological state different from the path- 

 ological state coded in Field E, use Symbol and, if the structure in this secondary pathological 

 state is an organ, code It in Field H-2 (if it is a tissue, it can not be coded In Field I). 



HOST (OR ORGAN, TISSUE, OR CELL SITE OF THE PATHOLOGY) IS IN AN INACTIVE STATE; e. g. , 

 hypnosis, estivation, diapause, dormancy, bacterial resting stage, hibernation. 



PARABIOTIC 



PARTHENOGENETIC 



HOST (OR ORGAN, TISSUE, OR CELL SITE OF THE PATHOLOGY) IS HORMONE DEFICIENT (the 

 deficiency not being the condition treated). Symbol B has priority over Symbol P in Field L 

 and is used for any experimental hormone deficiency. When an endocrine gland is extirpated 

 to produce the hormone deficient state (when the deficiency is not a condition being treated), 

 code the gland removed or modified in Field H-2. This includes situations in which the hormone 

 deficiency is relative only to the developmental state of the host being treated with the test 

 compound. 



HOST (OR ORGAN, TISSUE, OR CELL SITE OF THE PATHOLOGY) HAS A HORMONE EXCESS (the 

 excess not being the condition treated). This includes situations in which the excess is rela- 

 tive only to the developmental stage of the host being treated with the test compound, 



HOST (OR ORGAN, TISSUE, OR CELL SITE OF THE PATHOLOGY) IS DEFICIENT IN ONE OR MORE 

 VITAMINS, ONE OR MORE MINERALS, ONE OR MORE SPECIFIC NUTRIENTS, OR WATER. (The 

 symbol is not used for general deficiency in nourishment. See Symbol E. ) Symbol D is used to 

 code incidental dietary deficiencies of normal host organisms. It is not a device for indicating 

 that the host is a special strain which can not synthesize the nutrient, vitamin, or inorganic 

 compound. Any special strain , such as one dependent on exogenous nutrient or vitamin sources, 

 is indicated by Symbol F. 



HOST (OR ORGAN, TISSUE, OR CELL SITE OF THE PATHOLOGY) IS UNDERNOURISHED; generally 

 deficient in nutrients; fasted, deficient in caloric intake. For the deficiency of a specific 

 essential dietary component, use Symbol D. 



HOST IS OF A SPECIAL STRAIN, selected, adapted, derived, mutant. (This excludes those special 

 strains for which are provided the specific symbols, G, H, I, or Y below. It also excludes 

 designation of taxonomic strains which have been adequately distinguished by special host 

 symbols in Field J. Symbol F (and Symbols G, H, I and Y) are used only to designate physio- 

 logical strains not distinguished by a unique strain name in Field J. (See also the Key, Specific 

 Directions and Explanations, Division 9. ) 



H 



HOST IS OF A STRAIN RESISTANT TO THE TEST COMPOUND , 

 (Use Symbol J for an individual host organism, of a non-resistant 

 strain, made resistant by prior exposure to the test compound. ) 

 A strain resistant to the test organism is indicated by Symbol Y. 



HOST IS OF A STRAIN SENSITIVE TO THE TEST COMPOUND . 

 (Use Symbol 6 for an individual host organism, of a non-resistant 

 strain, sensitized to the test compound by previous exposure. ) 



HOST IS OF A STRAIN DEPENDENT ON THE TEST COMPOUND. 



Use Symbol F for an 

 organism of a strain 

 > resistant to, sensitive 

 to, or dependent on 

 compounds other than 

 the test compound 



HOST (OR ORGAN, TISSUE, OR CELL SITE OF THE PATHOLOGY), IS OF A NON-RESISTANT STRAIN 

 AND IS MADE RESISTANT TO (I. E. , TOLERANT OF) THE TEST COMPOUND . (Use Symbol 6 for 

 the state of sensitization to the test compound. For a resistant strain , use Symbol G). A host 

 made resistant to the test organism is indicated by Symbol Y.
