Pathogens and Protocols

MicrobeNet Pathogen Database

As of 2016, the MicrobeNet database contains complete information on more than 2,400 pathogens:

  • More than 2,000 bacteria: examples of rare bacteria completely characterized in MicrobeNet are Nocardia, Neisseira, Brevibacterium, Corynebacterium, Gordonia, Klebsiella, and Haemophilus.
  • More than 400 fungi, including Histoplasma capsulatum, Blastomyces dermatitidis, and Coccidioides immitis/posadasii, all of which are dangerous organisms causing significant disease and even death in otherwise healthy individuals.

Coccidioides immitis

Corynebacterium diphtheriae

image of H. influenzae (including Hib) is a bacterium that can cause a severe infection, occurring mostly in infants and children younger than five years of age.

Haemophilus influenza

image of Klebsiella is a type of Gram-negative bacteria that can cause different types of healthcare-associated infections, including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis

Klebsiella pneumoniae

Protocols

Protocols developed and validated by CDC experts are available on MicrobeNet.

  • More than 2,000 bacteria including: Esculin, Amino Acid Metabolism, Antibiotic Susceptibility Testing, and Sugar Fermentation.
  • Identification of fungi: Sugar Fermentation and Assimilation, Nitrate Assimilation, Urea Hydrolysis, Cycloheximide Susceptibility.
