AEROMONAS PSEUDO SELECTIVE AGAR

Aeromonas may not be truly indigenous to the marine environment, but may have a transient existence after entering salt water via rivers or sewage inputs. Foods that come in direct contact with water are likely sources of motile aeromonads, with fish and seafood products most often contaminated. Motile aeromonads can survive at low temperatures and therefore have been associated with refrigerated animal products such as chicken, dairy products, raw milk and vegetables. The predominant organism found in these foods is Pseudomonas species with the motile aeromonads present in lower numbers. Pseudomonas are capable of causing spoilage because they are psychrotrophic and thus multiply at refrigeration temperatures. Also they attack various substances in the food to produce compounds associated with off-flavour and off-odours. Aero Pseudo Selective Agar medium has been proposed by Kielwein for detecting Pseudomonas and Aeromonas in foodstuffs, waste water and equipments used in the food industry.
