Microbial Taxonomy

Taxonomy is the science of naming, classifying, and describing organisms. The taxonomy will include all the plants, microorganisms, and animals on this planet. Carl Linnaeus coined the taxonomy term. He is known as the father of taxonomy. Microbial taxonomy is a criterion of grouping microorganisms into groups based on their similarities and past relatedness. Microorganisms belonging to the same group are differentiated from the others via grouping into categories. This differentiation makes the study of microorganisms easy. There are different types of microbial taxonomies like Numerical and Molecular taxonomy. The study of microorganisms is known as microbiology. Microbiology is a broad term that takes into account microbial cultures, taxonomic studies, evolutionary relationships. Microbial interaction and diversity are huge data that needs to be compiled under the subject of microbiology. Microbiology covers various organisms like bacteria, fungi, algae, plants, animals, etc.

At autopsy, the most prominent findings were bronchopneumonia with focal organization and hemorrhage in the right lung. Stains of the lung tissue were negative by Gram, methenamine silver, and acid-fast methods, but Dieterle silver stains revealed short bacilli. Lung cultures yielded Gram-negative bacilli, which grew aerobically on buffered charcoal-yeast extract, but not on blood or chocolate agar. The organisms resembled Legionella, but failed to stain with immunofluorescence conjugates for Legionella pneumophila and multiple other species (L minded, L longbeachae, L gormanii, L dumoffi, L bozemanii). The organism was sent to the Centers for Disease Control and Prevention, where it was eventually identified as a new species of Legionella. What is the most probable source of this man's infection?

Kousei works at a company that produces sweetened condensed milk. If one or more samples exceed 104 bacterial CFU/mL (or CFU/g) the entire lot produced will be rejected. Kousei's boss, Kaori, wanted to know if the lot passed the FDA guidelines. The following bacterial counts were obtained after serial dilution and pour plating of the samples: Type of Dilutions plated 10-4 10-³ 10'5 Colony Plate 1 Plate 2 Plate 1 Plate 2 Plate 3 Plate 1 Plate 2 Plate 3 Plate 3 244 Bacteria 288 251 99 81 75 24 21 15 Based on the bacterial counts obtained, will the lot be rejected? Yes, because the computed CFU/mL is 2.5 x 10^7 OYes, because the computed CFU/mL is 3.0 x 10^6 No, because the computed CFU/mL is 3.0 x 10^3 No, because the computed CFU/mL is 2.5 x 10^3 OYes, because the computed CFU/mL is 3.8 x 10^5 O No, because the computed CFU/mL is 3.0 x 10^3 O Information is lacking so CFU/mL cannot be computed
Given the illustration and values below, determine the concentration of the original sample. Report results in CFU/mL or colony-forming unit/milliliter. Note that in order to observe the accuracy of results, culture plates with countable colonies between 25-250 CFU are considered in standard bacterial plate count.
