In genetics, a strain is said to be auxotrophic if it carries a mutation that renders it unable to synthesize an essential compound. For example, a yeast mutant with an inactivated uracil synthesis pathway gene is a uracil auxotroph (e.g., if the yeast Orotidine 5'-phosphate decarboxylase gene is inactivated, the resultant strain is a uracil ...
C. tropicalis is positive for the germ tube test. Germ tube test allows for distinguishing between C. tropicalis and C. albicans or C. dubliniensis . A short hyphal extension seen laterally from a yeast cell with no constriction at the point of origin is identified as C. albicans or C. dubliniensis , whereas C. tropicalis shows blastoconidial ...
Next to the above-mentioned selection makers a few auxotrophic strains were generated to work with auxotrophic makers. The URA3 marker (URA3 blaster method) is an often-used strategy in uridine auxotrophic strains; however, studies have shown that differences in URA3 position in the genome can be involved in the pathogeny of C. albicans.

Because the test pad reaction is dependent on pH, false positive results can occur if the urine is highly alkaline. [ 60 ] [ 62 ] Conventional test strips are not sensitive enough to reliably detect microalbuminuria , a condition in which urine albumin levels are slightly elevated, [ 64 ] although dipsticks specialized for this measurement exist.
While Candida albicans is the most common yeast species associated with vaginal thrush, infection by other types of yeast can produce similar symptoms. A Hungarian study of 370 patients with confirmed vaginal yeast infections identified the following types of infection: [18] Candida albicans: 85.7%; Non-albicans Candida (8 species): 13.2%
In hospitalized patients who develop candidemia, age is an important prognostic factor. Mortality following candidemia is 50% in patients aged ≥75 years and 24% in patients aged <75 years. [ 75 ] Among individuals being treated in intensive care units , the mortality rate is about 30–50% when systemic candidiasis develops.
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
Fungemia is the presence of fungi or yeast in the blood.The most common type, also known as candidemia, candedemia, or systemic candidiasis, is caused by Candida species. . Candidemia is also among the most common bloodstream infections of any ki
