Aerococcus

Aerococcus is a genus in the phylum Firmicutes (Bacteria).[1] The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters.[2] They were subsequently found in hospital environments and meat-curing brines.[3] It has been difficult to identify as it resembles alpha-hemolytic Streptococcus on blood agar plates and is difficult to identify by biochemical means.[4] Sequencing of 16S rRNA has become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species.[4]

Etymology

The name Aerococcus derives from the Greek aer, aeros (ἀήρ, ἀέρος), air; New Latin coccus (from Greekkokkos (κόκκος)), a berry; New Latin Aerococcus, air coccus.[5] The name was given based on its round shape and that it was first discovered in air samples.[2]

Species

The genus contains these species:[5]

  • A. christensenii Collins et al., 1999, named after the Danish microbiologist Jens J. Christensen[6]
  • A. sanguinicola Lawson et al., 2001 (from the Latin for blood-dweller)[7]
  • A. suis Vela et al., 2007 (Latin for "of a hog")[8]
  • A. urinae Aguirre & Collins, 1992 (Latin for "of urine")[9]
  • A. urinaeequi (Garvie, 1988) Felis et al., 2005 (Latin for "of the urine of a horse", source of isolation of the type strain)[10]
  • A. urinaehominis Lawson et al., 2001 (Latin for "of the urine of a human", source of isolation of the type strain)[11]
  • A. viridans Williams et al., 1953 – type species of the genus (Latin for "making green", producing a green color).[12] Causative agent of gaffkaemia, a disease of lobsters.[13]
