Includes a description of the Alpha-, Beta-, Delta-, and Epsilonproteabacteria (1256 pages, 512 figures, and 371 tables). This large taxa include many well known medically and environmentally important groups. Especially notable are Acetobacter, Agrobacterium, Aquospirillum, Brucella, Burkholderia, Caulobacter, Desulfovibrio, Gluconobacter, Hyphomicrobium, Leptothrix, Myxococcus, Neisseria, Paracoccus, Propionibacter, Rhizobium, Rickettsia, Sphingomonas, Thiobacillus, Xanthobacter and 268 additional genera.

The first thing you'll need to do is determine your unknown's group number. To do that, you will need to consult Bergey's Manual of Determinative Bacteriology (9th edition). To find your group number, look through the table of contents of the manual, and use the table that starts on page 17. Most unknowns will be in one of these groups:

  • Gram-Negative, Aerobic/Microaerophilic Rods and Cocci --Group 4
  • Facultatively Anaerobic Gram-Negative Rods --Group 5
  • Gram-Positive Cocci --Group 17
  • Endospore-Forming Gram-Positive Rods and Cocci --Group 18
  • Regular, Nonsporing Gram-Positive Rods --Group 19
  • Irregular, Nonsporing Gram-Positive Rods --Group 20
  • Aerobic, Nonmotile, Nonsporing, Acid-fast, Weakly Gram-Positive Rods --Group 21

Once you think you know your group number (or you have a few possibilities) go to the pages for your group within the manual. From there, you should find more information to help you make a final determination that you have the right group. You might also consult the information below to help you find the best tables to make a final determination about your unknown's group number:

Step 2: Determine the genus of your unknown.

Bergey Manual Of Systematic Bacteriology Flowchart 2019

To determine the genus of your unknown, you'll need to keep using Bergey's Manual of Determinative Bacteriology (9th edition). You should have the right group number by now, so go to the pages for your group. These pages should help you identify the genus of your unknown. There might be both tables and descriptions to help you identify the genus. You might find more than one possible match -- that's ok. The next step should provide more information to help you narrow down to a final choice.

Step 3. Read about your genus to make sure you have a match.

Step 4. Identify your unknown to the species level.

The genus description should contain information that helps you differentiate the species in your genus – so, you can compare your lab results to attempt to identify the species of your unknown. Be sure to read both the genus and the species descriptions, because characteristics listed in the genus description aren’t repeated in the species description!

Step 5. Troubleshoot problems.

If you find that the tables in Bergey's Manual of Determinative Bacteriology, 9th edition only allowed you to identify your bacteria down to the family level, then search the Systematic manual (link provided above) for your family name to see if the family description contains the tables you need to narrow down from family to genus. If the Systematic manual DOESN’T contain the tables you need, then you’ll have to come to the Main Desk at Cline Library and to once again consult Bergey's Manual of Determinative Bacteriology, 9th edition. Look up your family name in the index of the Determinative manual to see if there are tables you need that you previously missed.

Also keep in mind that sometimes a taxonomic name can be declared a synonym of another name, and thus is no longer used. Try looking your name up in either of these two resources:

If you find that another name is being used, look that name up in Bergey's instead. For example, the genus name Aurobacterium has been synonomized with Microbacterium, so you'd look up Microbacteriuminstead
