in nutrient agar:- 2-3mm, grey colonies,moist circular,convex colonies are seen.in blood:-grey colonies.in macConkey agar:-pale /yellowcolonies are seen.in deoxycholatecitrate agar:-colourless,smooth,shiny colonies salmonella are seen.
Salmonella bacteria are rod-shaped, gram-negative organisms that typically appear as tiny, colorless colonies on agar plates. Under a microscope, they can be seen as small, motile rods with flagella. In food or water, Salmonella cannot be visually detected without specialized equipment.
SMID means "Salmonella Identification." It is an agar made by bioMerieux that contains chemicals which change color when salmonella is grown on the plate. SMID2 is the new-and-improved version.
The biochemical test commonly used to identify Salmonella typhi is the Widal test. This test detects antibodies produced in response to a Salmonella typhi infection by measuring agglutination (clumping) reactions between the bacteria and specific antibodies in the patient's serum. Other tests like blood culture and polymerase chain reaction (PCR) can also be used for confirmation.
Typhoid fever is caused by the bacteria salmonella typhi; it is a gram-negative, short bacillus (rod-shape), with peritrichous flagella (many projecting in all directions). It is a type of salmonella bacteria. Typhoid belongs to the family Enterobacteriaceae, the same as E. coli.On Agar the colonies appear white in color, round, and low-convex in elevation.On Bismuth Sulfite agar it will form round black colonies that are surrounded by a relatively large black zone. This zone should have a distinct metallic sheen in the light.
Escherichia coli will appear as dark purple colonies with a green metallic sheen on EMB agar due to its ability to ferment lactose and produce acid.

No, Salmonella Typhimurium cannot grow on Mannitol Salt Agar because it is a selective and differential media primarily used for isolating and differentiating Staphylococcus species based on their ability to ferment mannitol. Salmonella Typhimurium is not a mannitol fermenter, so it will not grow on this agar.
Its color is red.
Shigella and the majority of salmonellae Clear, colorless, transparent Salmonella enteriditis ATCC 13076 Colorless with black center Salmonella typhi ATCC 6539 Colorless with black center Salmonella typhimurium ATCC 14028 Colorless with black center
The color of salmonella in bismuth sulphite agar is brown to black color with metallic sheen.

MacConkey agar: Selective for Gram-negative bacteria, inhibits the growth of Gram-positive bacteria. Hektoen enteric agar: Selective for Gram-negative enteric pathogens, such as Salmonella and Shigella species. Thiosulfate-citrate-bile salts-sucrose (TCBS) agar: Selective for Vibrio species, especially Vibrio cholerae. Cefsulodin-irgasan-novobiocin (CIN) agar: Selective for Yersinia species.

No it doesn't because it doesn't ferment mannitol. P. mirabilis can actually grow on a MAC agar, but it is colorless. I actually had this lab in Micro260 today.An MSA agar has 7% high salt concentration and provides growth for S. aureus bacteria turning it yellow/gold. An MSA agar is selective for osmotolerant bacteria meaning for bacteria that can grow in different salt concentrations, and it's differential because it can ferment mannitol.
Spring Tides I'd guess.
