TSI agar slant results: (from left) preinoculated (as control), P. aeruginosa, E. coli, Salmonella Typhimurium, Shigella flexneri The Triple Sugar Iron (TSI) test is a microbiological test roughly named for its ability to test a microorganism's ability to ferment sugars and to produce hydrogen sulfide. [1]
Hektoen enteric agar (HEK, HE or HEA) is a selective and differential agar [1] primarily used to recover Salmonella and Shigella from patient specimens. HEA contains indicators of lactose fermentation and hydrogen sulfide production; as well as inhibitors to prevent the growth of Gram-positive bacteria.
Salmonella species: red colonies, some with black centers. The agar itself will turn red due to the presence of Salmonella type colonies. Shigella species: red colonies. Coliforms: yellow to orange colonies. Pseudomonas aeruginosa: pink, flat, rough colonies. This type of colony can be easily mistaken for Salmonella due to the color similarities.
A foul or unusual smell could be a sign of a urinary tract infection. Consuming certain foods, particularly those that are spicy or contain strong ingredients, can also affect the odor of your urine.
Test strips contain pads impregnated with chemical compounds that change color when they interact with specific elements in the sample, such as glucose, protein and blood, [10] and microscopic examination permits the counting and classification of solid elements of the urine, such as cells, crystals, and bacteria. [11] Urinalysis is one of the ...
The forms of localized Salmonella infections are arthritis, urinary tract infection, infection of the central nervous system, bone infection, soft tissue infection, etc. [81] Infection may remain as the latent form for a long time, and when the function of reticular endothelial cells is deteriorated, it may become activated and consequently, it ...
The term is usually restricted to Shigella infections. [2] Shigellosis is caused by one of several types of Shigella bacteria. [3] Three species are associated with bacillary dysentery: Shigella sonnei, Shigella flexneri and Shigella dysenteriae. [4] A study in China indicated that Shigella flexneri 2a was the most common serotype. [5]
Shigella is a leading cause of bacterial diarrhea worldwide, with 80–165 million annual cases (estimated) [6] and 74,000 to 600,000 deaths. [ 6 ] [ 7 ] It is one of the top four pathogens that cause moderate-to-severe diarrhea in African and South Asian children.
