Bismuth Sulfite Agar
Bismuth Sulfite Agar is used for the isolation of Salmonella spp. A modification by Wilson and Blair, Bismuth Sulfite Agar uses Bismuth and Sodium Sulfite for the selective isolation of typhoid and non-typhoid Salmonella strains. This medium is used particularly for the isolation of Salmonella typhi from clinical and environmental specimens including food, feces, urine, and sewage. Bismuth and Brilliant Green dye act as inhibitors to most enteric bacteria and Gram-positive microorganisms but allow Salmonella typhi to produce black colonies surrounded by a metallic sheen due to the precipitation of iron from Ferrous Sulfate upon reduction to H2S. There is a choice of 3 sizes - 500g, 2kg, and 10kg.
PREPARATION: Add 52 grams of the medium into one liter of purified water. Heat with continuous stirring. Bring to a boil for one minute and allow to cool to 45-50°C. This medium should not be autoclaved. Dispense into sterile petri dishes and allow to solidify.

Solid watch for the price
I have numerous nicer watches and often times I find myself wearing my Casio instead. The dial looks very striking for such an inexpensive watch and you don’t need to wind it so it always keeps time. The brushed metal looks very nice too. It’s pretty light weight and fits my wrist fine although I had to remove links when I got it. It’s also very easy to read. Would recommend

Very nice watch
Nice watch. Took me 5 mins to adjust the watch wrist, not bad at all, go watch YouTube if you don’t know how to adjust the wrist, very easy.
