Dichotomous Key to Identifying Eight Bacteria Alcaligenes faecalis Mycobacterium smegmatis Citrobacter freundii Mycobacterium leprae Pseudomonas fluorescens Corynebacterium xerosis Streptococcus pneumoniae Aeromonas hydrophila 7. 26–29 Achromobacter xylosoxidans and Alcaligenes faecalis are the most common isolates and agents of human disease in these genera, but little is known about factors promoting virulence. [1] Achromobacter signifies colorless rodlet and xylosoxidans implies oxidizing xylose. •Find the characteristics that set certain organisms apart from others in the group •e.g A. faecalis and A. viscolactis are both gram negative and have all the same characteristics… except A. faecalis tests positive for Dextrose (with gas) and also for Phenylalanine deaminase •Utilize these characteristics to continue your flow chart Figure 1 illustrates three general colonytypes observedamongthe isolates. Alcaligenes faecalis is a Gram-negative catalase- and oxidase-positive, motile rod. It has been associated with nosocomially acquired septicemia and pyrexic reactions without septicemia. 2. It seems to be well established, however, that the organism can be pathogenic. Particularly in immunosuppressed people, the opportunistic pathogen may trigger local infections, including peritonitis, meningitis, otitis media, appendicitis, and bloodstream infection.
