Bacteria (<i>Rickettsia</i>, <i>Chlamydia</i>) biosafety and biodefense category list comparison.

aNIH laboratory biosafety categorization: Yersinia pestis specifically pgm(–) strains (lacking the 102 kb pigmentation locus) and lcr(–) strains (lacking the LCR plasmid) are in group 2. bNIH laboratory biosafety categorization: Francisella tularensis subspecies novicida, strain Utah 112; F. tularensis subspecies holarctica LVS; F tularensis biovar tularensis strain ATCC 6223 are in group 2. EU laboratory biosafety categorization, F. tularensis type A is in group 3, while type B is in group 2. cBiosecurity categorization: Clostridium botulinum, Staphylococcus aureus and Clostridium perfringens are listed as Clostridium botulinum toxin, Staphylococcal enterotoxin B, epsilon toxin of Clostridium perfringens. dChinese laboratory biosafety categorization: Rickettsia spp is in group 2. eNIH laboratory biosafety categorization: Coxiella burnetii – specifically the Phase II, Nine Mile strain, plaque purified, clone 4 is in group 2. fChinese laboratory biosafety categorization: Vibrio cholerae epidemic strains are managed as risk group 2, non-epidemic strains are managed as risk group 3. gEU laboratory biosafety categorization: Salmonella typhi is in group 3, while other salmonella strains are in group 2. hEU laboratory biosafety categorization: Shigella dysenteriae type 1 is in group 3, while other strains are in group 2. iChinese laboratory biosafety categorization: pathogenic Escherichia coli are listed. jEU laboratory biosafety categorization: Chlamydia psittaci avian strains are in group 3, while other strains are in group 2. “Chlamydia psittaci” is now reclassified as “Chlamydophila psittaci”.
