Abstract
AIM: To investigate the extrahospital reservoirs of Acinetobacter spp. in Lebanon. MATERIALS & METHODS: Two thousand three hundred and sixty-one samples from different ecological niches were analyzed by culture methods. Species identification was confirmed by rpoB-gene sequencing. Multilocus sequence typing was used to characterize the Acinetobacter baumannii clones. RESULTS & CONCLUSION: Acinetobacter spp. were detected in 14% of environmental samples and 8% of food samples. Furthermore, 9% of animals and 3.4% of humans were colonized. Non-baumannii Acinetobacter were the most common species isolated and newly susceptible A. baumannii clones were detected. Interestingly, 21 isolates were not identified at the species level and were considered as putative novel species. To our knowledge, this is the largest epidemiological study investigating the epidemiology of Acinetobacter spp. outside hospitals.
