APPENDIX C.     EXEMPTIONS UNDER SECTION III-F-6

 

Section III-F-6 states that exempt from these NIH Guidelines are "those that do not present a significant risk to health or the environment (see Section IV-C-1-b-(1)-(c), NIH Director--Specific Responsibilities), as determined by the NIH Director, with the advice of the RAC, and following appropriate notice and opportunity for public comment.  See Appendix C, Exemptions under Sections III-F-6, for other classes of experiments which are exempt from the NIH Guidelines."  The following classes of experiments are exempt under Section III-F-6:

 

Appendix C-I.    Recombinant DNA in Tissue Culture

 

Recombinant DNA molecules containing less than one-half of any eukaryotic viral genome (all viruses from a single family being considered identical -- see Appendix C-IX-E, Footnotes and References of Appendix C), that are propagated and maintained in cells in tissue culture are exempt from these NIH Guidelines with the exceptions listed in Appendix C-I-A.

 

Appendix C-I-A.  Exceptions 

 

The following categories are not exempt from the NIH Guidelines:  (i) experiments described in Section III-B which require NIH/OBA and Institutional Biosafety Committee approval before initiation, (ii) experiments involving DNA from Risk Groups 3, 4, or restricted organisms (see Appendix B, Classification of Human Etiologic Agents on the Basis of Hazard, and Sections V-G and V-L, Footnotes and References of Sections I through IV) or cells known to be infected with these agents, (iii) experiments involving the deliberate introduction of genes coding for the biosynthesis of molecules that are toxic for vertebrates (see Appendix F, Containment Conditions for Cloning of Genes Coding for the Biosynthesis of Molecules Toxic for Vertebrates), and (iv) whole plants regenerated from plant cells and tissue cultures are covered by the exemption provided they remain axenic cultures even though they differentiate into embryonic tissue and regenerate into plantlets.

 

Appendix C-II.   Escherichia coli K-12 Host-Vector Systems

 

Experiments which use Escherichia coli K-12 host-vector systems, with the exception of those experiments listed in Appendix C-II-A, are exempt from the NIH Guidelines provided that:  (i) the Escherichia coli host does not contain conjugation proficient plasmids or generalized transducing phages; or (ii) lambda or lambdoid or Ff bacteriophages or non-conjugative plasmids (see Appendix C-IX. Footnotes and References of Appendix C, Footnotes and References of Appendix C) shall be used as vectors.  However, experiments involving the insertion into Escherichia coli K-12 of DNA from prokaryotes that exchange genetic information (see Appendix C-IX. Footnotes and References of Appendix C, Footnotes and References of Appendix C) with Escherichia coli may be performed with any Escherichia coli K-12 vector (e.g., conjugative plasmid).  When a non-conjugative vector is used, the Escherichia coli K-12 host may contain conjugation-proficient plasmids either autonomous or integrated, or generalized transducing phages.  For these exempt laboratory experiments, Biosafety Level (BL) 1 physical containment conditions are recommended.  For large-scale fermentation experiments, the appropriate physical containment conditions need be no greater than those for the host organism unmodified by recombinant DNA techniques; the Institutional Biosafety Committee can specify higher containment if deemed necessary.

 

Appendix C-II-A.   Exceptions 

 

The following categories are not exempt from the NIH Guidelines:  (i) experiments described in Section III-B which require NIH/OBA and Institutional Biosafety Committee approval before initiation, (ii) experiments involving DNA from Risk Groups 3, 4, or restricted organisms (see Appendix B, Classification of Human Etiologic Agents on the Basis of Hazard, and Sections V-G and V-L, Footnotes and References of Sections I through IV) or cells known to be infected with these agents may be conducted under containment conditions specified in Section III-D-2 with prior Institutional Biosafety Committee review and approval, (iii) large-scale experiments (e.g., more than 10 liters of culture), and (iv) experiments involving the cloning of toxin molecule genes coding for the biosynthesis of molecules toxic for vertebrates (see Appendix F, Containment Conditions for Cloning of Genes Coding for the Biosynthesis of Molecules Toxic for Vertebrates).

 

Appendix C-III.    Saccharomyces Host-Vector Systems

 

Experiments involving Saccharomyces cerevisiae and Saccharomyces uvarum host-vector systems, with the exception of experiments listed in Appendix C-III-A, are exempt from the NIH Guidelines.  For these exempt experiments, BL1 physical containment is recommended.  For large-scale fermentation experiments, the appropriate physical containment conditions need be no greater than those for the host organism unmodified by recombinant DNA techniques; the Institutional Biosafety Committee can specify higher containment if deemed necessary.

 

Appendix C-III-A.   Exceptions

 

The following categories are not exempt from the NIH Guidelines:  (i) experiments described in Section III-B which require NIH/OBA and Institutional Biosafety Committee approval before initiation, (ii) experiments involving DNA from Risk Groups 3, 4, or restricted organisms (see Appendix B, Classification of Human Etiologic Agents on the Basis of Hazard, and Sections V-G and V-L, Footnotes and References of Sections I through IV) or cells known to be infected with these agents may be conducted under containment conditions specified in Section III-D-2 with prior Institutional Biosafety Committee review and approval, (iii) large-scale experiments (e.g., more than 10 liters of culture), and (iv) experiments involving the deliberate cloning of genes coding for the biosynthesis of molecules toxic for vertebrates (see Appendix F, Containment Conditions for Cloning of Genes Coding for the Biosynthesis of Molecules Toxic for Vertebrates).

 

Appendix C-IV.   Kluyveromyces Host-Vector Systems

 

Experiments involving Kluyveromyces lactis, host-vector systems, with the exception of experiments listed in Appendix C-IV-A, are exempt from the NIH Guidelines provided laboratory-adapted strains are used (i.e. strains that have been adapted to growth under optimal or defined laboratory conditions). For these exempt experiments, BL1 physical containment is recommended. For large-scale fermentation experiments, the appropriate physical containment conditions need be no greater than those for the host organism unmodified by recombinant DNA techniques; the Institutional Biosafety Committee may specify higher containment if deemed necessary.  

 

Appendix C-IV-A.   Exceptions

 

The following categories are not exempt from the NIH Guidelines:  (i) experiments described in Section III-B which require NIH/OBA and Institutional Biosafety Committee approval before initiation, (ii) experiments involving DNA from Risk Groups 3, 4, or restricted organisms (see Appendix B, Classification of Human Etiologic Agents on the Basis of Hazard, and Sections V-G and V-L, Footnotes and References of Sections I through IV) or cells known to be infected with these agents may be conducted under containment conditions specified in Section III-D-2 with prior Institutional Biosafety Committee review and approval, (iii) large-scale experiments (e.g., more than 10 liters of culture), and (iv) experiments involving the deliberate cloning of genes coding for the biosynthesis of molecules toxic for vertebrates (see Appendix F, Containment Conditions for Cloning of Genes Coding for the Biosynthesis of Molecules Toxic for Vertebrates).

 

Appendix C-V.   Bacillus subtilis or Bacillus licheniformis Host-Vector Systems

 

Any asporogenic Bacillus subtilis or asporogenic Bacillus licheniformis strain which does not revert to a spore-former with a frequency greater than 10-7 may be used for cloning DNA with the exception of those experiments listed in Appendix C-V-A, Exceptions.  For these exempt laboratory experiments, BL1 physical containment conditions are recommended.  For large-scale fermentation experiments, the appropriate physical containment conditions need be no greater than those for the host organism unmodified by recombinant DNA techniques; the Institutional Biosafety Committee can specify higher containment if it deems necessary.

 

Appendix C-V-A.   Exceptions

 

The following categories are not exempt from the NIH Guidelines:  (i) experiments described in Section III-B which require NIH/OBA and Institutional Biosafety Committee approval before initiation, (ii) experiments involving DNA from Risk Groups 3, 4, or restricted organisms (see Appendix B, Classification of Human Etiologic Agents on the Basis of Hazard, and Sections V-G and V-L, Footnotes and References of Sections I through IV) or cells known to be infected with these agents may be conducted under containment conditions specified in Section III-D-2 with prior Institutional Biosafety Committee review and approval, (iii) large-scale experiments (e.g., more than 10 liters of culture), and (iv) experiments involving the deliberate cloning of genes coding for the biosynthesis of molecules toxic for vertebrates (see Appendix F, Containment Conditions for Cloning of Genes Coding for the Biosynthesis of Molecules Toxic for Vertebrates).

The breeding of two different transgenic rodents or the breeding of a transgenic rodent and a non-transgenic rodent with the intent of creating a new strain of transgenic rodent that can be housed at BL1 containment will be exempt from the NIH Guidelines if:

(1) Both parental rodents can be housed under BL1 containment; and

(2) neither parental transgenic rodent contains the following genetic modifications: (i) incorporation of more than one-half of the genome of an exogenous eukaryotic virus from a single family of viruses; or (ii) incorporation of a transgene that is under the control of a gammaretroviral long terminal repeat (LTR); and

(3) the transgenic rodent that results from this breeding is not expected to contain more than one-half of an exogenous viral genome from a single family of viruses.

 

Appendix C-IX.    Footnotes and References of Appendix C

 

Appendix C-IX-A.  The NIH Director, with advice of the RAC, may revise the classification for the purposes of these NIH Guidelines (see Section IV-C-1-b-(2)-(b), Minor Actions).  The revised list of organisms in each Risk Group is located in Appendix B.

 

Appendix C-IX-B.  A subset of non-conjugative plasmid vectors are poorly mobilizable (e.g., pBR322, pBR313).  Where practical, these vectors should be employed.

 

Appendix C-IX-C.  Defined as observable under optimal laboratory conditions by transformation, transduction, phage infection, and/or conjugation with transfer of phage, plasmid, and/or chromosomal genetic information.  Note that this definition of exchange may be less stringent than that applied to exempt organisms under Section III-F-5, Exempt Experiments.

 

Appendix C-IX-D.  As classified in the Third Report of the International Committee on Taxonomy of Viruses:  Classification and Nomenclature of Viruses, R. E. F. Matthews (ed.), Intervirology 12 (129-296), 1979.

 

Appendix C-IX-E.  i.e., the total of all genomes within a Family shall not exceed one-half of the genome.
