Explanation / Answer
Answer:
Favourite creature - A bacteria Escherichia coli: Gram negative, rod shaped coliform bacteria.
E.coli is an interesting bacteria because it have good and harmful effects in human body and it is used as model organism for lot of reasearch.
E.coli can determine the source of fecal contamination in environmental samples. Knowing which E. coli strains are present in a water sample allows researchers to make assumptions about whether the contamination originated from a human, another mammal, or a bird.
The primary habitat of Escherichia coli is the vertebrate gut, where it is the predominant aerobic organism, living in symbiosis with its host. Despite the occurrence of recombination events, the population structure is predominantly clonal, allowing the delineation of major phylogenetic groups.
The main symptoms of an E. coli intestinal infection are: Bloody diarrhea., Stomach cramps., Nausea ,vomiting
As per WHO guidelines:
-Shiga toxin-producing E. coli (STEC) is a bacterium that can cause severe foodborne disease.
--STEC can grow in temperatures ranging from 7 °C to 50 °C, with an optimum temperature of 37 °C. Some STEC can grow in acidic foods, down to a pH of 4.4, and in foods with a minimum water activity (aW) of 0.95.
-Primary sources of STEC outbreaks are raw or undercooked ground meat products, raw milk, and faecal contamination of vegetables.
-In most cases, the illness is self-limiting, but it may lead to a life-threatening disease including haemolytic uraemic syndrome (HUS), especially in young children and the elderly.
-STEC is heat-sensitive. So,"cook thoroughly".
