“…They were all found in animals or in animal-derived food and showed huge diversity in population structures. This diversity was not in accordance with the findings of Hamouda et al (30) (30). In addition, our results illustrate the usefulness of bla OXA-51 as a single-locus-based typing method (51).…”

“…These animals lived on farms or were wild animals and had never been in contact with a hospital environment, such as veterinary clinics. A. baumannii has previously been documented as an animal colonizer with different prevalences in different countries: in Senegal, 5.1% (20); in Scotland, 1.2% (30); and on La Reunion Island, 6.5% (31). We have also found the bacterium in food produced from animals, such as cow meat, raw cheese, and raw milk, reinforcing the idea that animals could be a potential reservoir of A. baumannii.…”

“…Although the ubiquitous existence of A. baumannii in nature has been considered a common misconception by some authors (7), several recent studies have undeniably highlighted the presence of extrahospital reservoirs (9,22,30,31,33). These observations have mainly been made through recent implementation of molecular methods, such as bla OXA-51 -like PCR or rpoB gene sequencing, improving detection and identification of A. baumannii and other species of the genus Acinetobacter (42,48,49).…”

“…The bla OXA-143 gene has recently been detected and reported only in Brazil and South Korea (50). Until now, most of the A. baumannii populations detected outside hospitals were susceptible to antibiotics (21,27,(30)(31)(32). However, there have been growing concerns after the description of a bla OXA-23 gene from human stool and lice in Senegal (20); NDM-1-producing A. baumannii tk;4from a pig in China (55); and other carbapenemase-producing Acinetobacter spp.…”

“…Finally, in animals, the bacterium has been described as an emerging pathogen in veterinary clinics in Germany (28) and Switzerland (29). It was also involved in asymptomatic carriage in some animals (20,30,31). Moreover, its presence was reported worldwide in human body and head lice (20,(32)(33)(34), as well as in arthropods (35).…”

The presence of Acinetobacter baumannii outside hospitals is still a controversial issue. The objective of our study was to explore the extrahospital epidemiology of A. baumannii in Lebanon. From February 2012 to October 2013, a total of 73 water samples, 51 soil samples, 37 raw cow milk samples, 50 cow meat samples, 7 raw cheese samples, and 379 animal samples were analyzed by cultural methods for the presence of A. baumannii. Species identification was performed by rpoB gene sequencing. Antibiotic susceptibility was investigated, and the A. baumannii population was studied by two genotyping approaches: multilocus sequence typing (MLST) and bla OXA-51 sequence-based typing (SBT). A. baumannii was detected in 6.9% of water samples, 2.7% of milk samples, 8.0% of meat samples, 14.3% of cheese samples, and 7.7% of animal samples. All isolates showed a susceptible phenotype against most of the antibiotics tested and lacked carbapenemase-encoding genes, except one that harbored a bla OXA-143 gene. MLST analysis revealed the presence of 36 sequence types (STs), among which 24 were novel STs reported for the first time in this study. bla OXA-51 SBT showed the presence of 34 variants, among which 21 were novel and all were isolated from animal origins. Finally, 30 isolates had new partial rpoB sequences and were considered putative new Acinetobacter species. In conclusion, animals can be a potential reservoir for A. baumannii and the dissemination of new emerging carbapenemases. The roles of the novel animal clones identified in community-acquired infections should be investigated.

Resistant Acinetobacter baumannii isolates are not only known as opportunistic nosocomial bacteria but may also be regarded as emerging bacterial contaminants in foods of animal origins. The present investigation was done to assess the prevalence and antibiotic resistance pattern of A. baumannii isolated from different types of raw meat samples. One hundred and ninety‐four raw meat samples were collected and cultured for A. baumannii isolates. Culture‐positive bacteria were also approved using the loop‐mediated isothermal amplification (LAMP) technique. The disc diffusion method was used for antibiotic susceptibility testing. Out of 194 raw meat samples, 39 (20.10%) were positive for A. baumannii isolates. Ovine raw meat was the most commonly contaminated samples (32.14%). All of the culture‐positive A. baumannii isolates were also approved using the LAMP assay. A. baumannii isolates harboured the highest prevalence of resistance against gentamicin (87.17%), tetracycline (79.48%), erythromycin (74.35%), azithromycin (66.66%), ciprofloxacin (58.97%), trimethoprim/sulphamethoxazole (56.41%) and rifampin (51.28%). The lowest prevalence of resistance was found against imipenem (17.94%) and chloramphenicol (28.20%). Raw bovine, ovine, caprine, camel and poultry meat samples were considered as the important sources of isolates resistant to some of the categories of antimicrobials used to treat infections caused by A. baumannii. Further studies are required to find the exact role of resistant A. baumannii isolates in the dissemination of antibiotic resistance to human population.
