A typical presentation of microbiological laboratory findings makes use of tables to prepare information. A desk designated as “Desk 5” doubtless comprises observations and interpretations associated to the expansion of micro organism on MacConkey agar, a selective and differential tradition medium. This medium is often used to isolate and differentiate gram-negative micro organism, significantly members of the Enterobacteriaceae household, primarily based on their potential to ferment lactose. The outcomes displayed in such a desk would possibly embrace colony morphology (colour, dimension, form), lactose fermentation (indicated by a colour change within the agar), and presumptive identification of bacterial species. A hypothetical instance can be the statement of pink colonies, indicating lactose fermentation, suggestive of organisms like Escherichia coli, whereas colorless colonies counsel non-lactose fermenters akin to Salmonella species.
Organized presentation of those findings facilitates clear comparability between completely different bacterial samples or experimental circumstances. This contributes to correct and environment friendly identification of bacterial isolates, which is essential for prognosis of infections, epidemiological research, and analysis in numerous fields like meals security and environmental microbiology. Traditionally, culture-based strategies, together with the usage of selective and differential media like MacConkey agar, have been important for understanding bacterial range and pathogenicity. These strategies stay invaluable instruments in fashionable microbiology laboratories.
