Alcaligenes spp

From Dog
Alcaligenes faecalis on agar culture

Alcaligenes spp are a Gram negative aerobic proteobacteria.

Closely related to Burkholderia spp, these bacteria are opportunistic organisms normally found in humid environments.

Species which are pathogenic to dogs include:

  • Alcaligenes faecalis
  • Alcaligenes xylosoxidans
  • Alcaligenes odorans[1]

In dogs, Acaligenes spp are part of the normal microflora of the skin[2], reproductive[3] and gastrointestinal tract[4], and have been reported in association with otitis externa and following prosthetic hip replacement[5].

Alcaligenes species are resistant to almost all antibiotics except gentamicin and colistin[6].
