Thermo Scientific™ MacConkey Agar without Salt (Dehydrated)

Description

• Detect and enumerate coliform organisms in clinical samples with Thermo Scientific™ Oxoid™ MacConkey Agar without Salt (Dehydrated)
• The differential medium suppresses swarming of Proteus species and is, therefore, recommended for urine examination in the investigation of suspected urinary tract infection (UTI)
• MacConkey Agar without Salt has the same formulation as MacConkey Agar except that it does not contain added salt and, therefore, provides a ‘low electrolyte medium’ on which most Proteus species do not spread
• The medium has found particular favor for use in the examination of urine samples so that overgrowth of other organisms is prevented
• Precautions: The colonial characteristics described give presumptive identification only of the isolated organisms
• It is necessary to subculture and carry out confirmation tests for final identification
• To enhance the pigment of suspected Staphylococcus aureus , hold the plates on the bench at ambient temperature for 12-18 hours
• This medium may produce a discrete precipitate on cold storage of 2 - 10°C
• This in no way affects the performance of the medium.
