Summary Introduction
Introduction:
Unicellular organism causes disease to humans like bacteria, archae etc. These organisms usually get into humans via opportunistic and contamination mode.
Case summary:
Some unicellular organisms are discussed in this case with the morphological and physiological character and also the sequence similarity of r RNA base. Comparing the two dichotomous key for these organisms, suggest which key is useful in laboratory identification and for classification.

Bacillus cereus and Bacillus thuringiensis are very closely related species and cannot be distinguished clearly by biochemical tests and 16S rRNA sequencing. Designate TWO (2) ways that you may use to differentiate these two species.
What possible explanations have been proposed for the origins of H. luzonensis? In your own words, describe the evidence that supports these explanations. (Minimum of 2 complete sentences.)
How was Brocadia anammoxidan named? What or who was it named after?
(Organisms are often named for where they were found, unique morphological or metabolic features, name of the person who discovered it, etc. Attempt both genus and species name. For example, if my organism was Xanthomonas oryzae, I would Google “Xanthomonas word origin.” and “oryzae word origin.” Often a word origin is Greek or Latin, so Google your word followed by “Greek” or “Latin”)

- What is the generic namearrow_forwardIn 1971, Dr. Akira Endo, working at the Sankyo company in Tokyo speculated that fungi not only contained antibiotics but also inhibitors of other processes such as cholesterol metabolism. Over a period of several years, he screened more than 6,000 fungal cultures until a positive result emerged. This compound, which was named compactin, came from the blue-green mold Penicillium citrinum Pen-5 that was isolated from a rice sample collected at a grain shop in Kyoto. Based on biochemical assays, compactin is the first known statin. 1. The original kinetics data for compactin inhibition of HMG-CoA reductase enzyme that was published by Dr. Endo in 1976 is shown on the right. a) Determine the Km and Vmax values for enzymatic activity.
