Acinetobacter pittii strain IEC338SC

Acinetobacter pittii strain IEC338SC is a Gram-negative, rod-shaped bacterium characterized as a chemoheterotrophic aerobe. This organism is notable for its ability to thrive in diverse habitats and has an optimal growth temperature of 37°C, classifying it as mesophilic. It possesses a unique cellular structure, featuring two membranes and four replicons, and is non-motile, though it has flagella. This strain is free-living, which means it does not rely on a host for survival, but it has been associated with several hosts, including Homo sapiens (humans), Felis catus (domestic cats), and Papaver somniferum (opium poppy). A. pittii strain IEC338SC is clinically significant due to its potential to cause various health issues, including pneumonia, peritonitis, bloodstream infections, and nosocomial infections, particularly in healthcare facilities. The bacterium's presence in multiple environments and its ability to cause infections highlight its adaptability and potential for persistence in clinical settings. The noted relationships with both humans and domestic animals suggest that A. pittii may play a role in zoonotic transmission or environmental reservoirs, contributing to its epidemiological relevance. Further research may elucidate its ecological roles and mechanisms of pathogenicity, given its association with significant health challenges in healthcare contexts.
