Hektoen Enteric Veg Agar is formulated by replacing animal base Proteose peptone by Veg Peptone No. 3 making it free from BSE/ TSE. Hektoen Enteric Veg Agar is the modification of Hektoen Enteric Agar which was formulated by King and Metzger and recommended by APHA.
Hoben et al added Novobiocin (15 mg/litre) to improve the selectivity of the conventional medium by inhibiting Citrobacter and Proteus species. Taylor and Schelhaut found the medium valuable for differentiating pathogenic organisms and for better growth of Shigella. Inoculate the medium with fresh faeces suspended in Ringers solution or inoculate directly with rectal swabs. Spread out the inoculum to obtain isolated colonies and incubate at 35?C for 18-24 hours. Further incubation will improve differentiation between Salmonellae and Shigellae. Proteus species may resemble Salmonellae or Shigellae, hence further testing must be carried out for confirmation.
for di?erential and selective isolation of Salmonella and Shigella species from pathological specimens
