gram negative enteric bacilli are fastidious heterotrophs.
Yes. Serratia is a Gram negative rod from the Enterobacteriaceae family. The Hektoen Enteric agar allows the growth of Gram negative bacteria while inhibiting growth of Gram positive bacteria.
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.
Yes, Staphylococcus aureus is negative for the methyl red test due to its inability to produce stable acids from glucose fermentation. This distinguishes it from other enteric bacteria that are positive for the methyl red test.
Campylobacter jejuni will not grow on MacConkey agar because it is a selective and differential medium designed to support the growth of Gram-negative enteric bacteria while inhibiting the growth of Gram-positive bacteria. Campylobacter jejuni is a Gram-negative bacterium, but it is not an enteric bacterium, so it lacks the specific enzymes needed to utilize the nutrients in MacConkey agar for growth.
Probably because that is where the gram negative bacteria have found a food source. Lactose is not the perfered diet, but it works and they are most likely there because they can tolerate the environment, and survive (on lactose) when their #1 food source is not available.

Mycobacterium phlei is a non-fastidious organism that is commonly found in soil and water. It is not commonly grown on Eosin Methylene Blue (EMB) agar, as EMB agar is more selective for gram-negative enteric bacteria. Instead, Mycobacterium phlei is typically cultured on media specifically designed for mycobacteria, such as Middlebrook agar or Lowenstein-Jensen agar.

Enteric fever is the name given to typhoid fever. It is caused by bacillus salmonella typhimurium. You do not have non salmonella enteric fever. So salmonella enteric is not very correct term. But still the term is used to stress the seriousness of the disease.

Example 1: Enteric pathogens if left untreated can lead to gastroenteritis. Example 2: The enteric emissions from the decay of dead animals can trigger an endemic in an open area.
Enteric tissue is found in the gastrointestinal tract. It lines the inner surface of the intestines and plays a crucial role in digestion and absorption of nutrients. Additionally, enteric tissue contains a complex network of nerves known as the enteric nervous system which helps regulate gut functions.
An enteric coating that covers medicinal pills is a barrier that controls where in the digestive system that the medicine will absorb. Which enteric coating on pills depends on where the medicine should be absorbed such as the stomach or small intestines.
You can identify an enteric-coated pill by checking the packaging or label, which typically indicates "enteric-coated" or "EC." Additionally, enteric-coated pills often have a distinct shiny or smooth appearance, and they may be colored differently from regular pills. If in doubt, consult a pharmacist or healthcare provider for confirmation.
