Acinetobacter lwoffii is a Gram negative, aerobic bacterium important in the skin microbiome and is found in the normal flora of the skin, oropharynx, and perineum (3). A. lwoffii lives on the skin of healthy humans, in soil and plants, in frozen foods and poultry, and in human specimens, such as blood and urine (3). However, it is dangerous upon entering the bloodstream as it is largely resistant to antimicrobials, meaning it can become dangerously pathogenic (3). A. lwoffii is one of the most frequent species found in hospital samples, after Acinetobacter baumannii (3, 4). A. lwoffii possesses the ability to survive and reproduce after desiccation in clinical and hospital environments at room temperature and is often a source of infection in hospital settings (5). Current research is focused on what mechanisms make A. lwoffii resistant to antimicrobials and allow it to survive harsh environmental conditions. | |||

2. Description and significance
Acinetobacter lwoffii is a Gram negative, aerobic bacterium important in the skin microbiome and is found in the normal flora of the skin, oropharynx, and perineum (3). A. lwoffii lives on the skin of healthy humans, in soil and plants, in frozen foods and poultry, and in human specimens, such as blood and urine (3). However, it is dangerous upon entering the bloodstream as it is largely resistant to antimicrobials, meaning it can become dangerously pathogenic (3).

Current research is focused on what mechanisms make A. lwoffii resistant to antimicrobials and allow it to survive harsh environmental conditions.
3. Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
4. Cell structure
Interesting features of cell structure. Can be combined with “metabolic processes”
5. Metabolic processes
Describe important sources of energy, electrons, and carbon (i.e. trophy) for the organism/organisms you are focusing on, as well as important molecules it/they synthesize(s).
6. Ecology
Habitat; symbiosis; contributions to the environment.
7. Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
8. Current Research
Include information about how this microbe (or related microbes) are currently being studied and for what purpose
