Seventeenth-century German image of Proteus, the Sea God

Proteus is a Greek god of the sea who is capable of changing his form at will.
This association explains the word “protean,” which is used to describe something extremely flexible or ever-changing. 

Though this god is not as well-known as some members of the Greek pantheon, he appeared in a few Greek myths, and his name suggests that he may be quite old, given that protos means “first” in Greek.

Proteus penneri

  • General information

    • the following information is not yet verified
      Family: Enterobacteriaceae
      P. vulgaris
      - P. penneri (= P. vulgaris genomosp 1)
      - P. hauseri (= P. vulgaris genomosp 3)

      Natural habitats
      Proteae occur in humans, animals and the environment, especially in locations where animal protein decomposes.

      Clinical significance
      They were isolated from wounds, soft tissue and urine

      P.vulgaris and P.penneri are easily isolated from individuals in long term care facilities and hospitals and from patients with underlying diseases or compromised immune systems.

      In people with congenital or anatomic abnormality of the urinary tract or a stone in the urinary tract, are predominantly Proteus (mostly P. mirabilis) infections.
      They quickly put this urea into ammonia, which creates an alkaline environment.

      This can be harmful to the kidney and promotes the formation of stones materials consist of a biochemical complex, which is called struvite.

      In the stone Proteus bacteria can survive despite therapy, leading to chronic UTI.
