“…Particular attention deserves also cow, sheep, goat, and camel raw meat that can be sources of A. baumannii strains harboring antimicrobial resistance genes for both community and hospital settings environment, posing a potential risk to public health [ 74 ]. Therefore, higher levels of food-related inspection are needed, and further studies are required to define the exact role of this zoonotic pathogen in the food-chain.…”

Acinetobacter baumannii is a Gram-negative, opportunistic pathogen, causing severe infections difficult to treat. The A. baumannii infection rate has increased year by year in human medicine and it is also considered as a major cause of nosocomial infections worldwide. This bacterium, also well known for its ability to form biofilms, has a strong environmental adaptability and the characteristics of multi-drug resistance. Indeed, strains showing fully resistant profiles represent a worrisome problem in clinical therapeutic treatment. Furthermore, A. baumannii-associated veterinary nosocomial infections has been reported in recent literature. Particularly, carbapenem-resistant A. baumannii can be considered an emerging opportunistic pathogen in human medicine as well as in veterinary medicine.

“… 26 CRAB was detected in 5.8% (3/52) and 11.2% (112/1000) poultry meat in Iran and Turkey, respectively. 45 , 46 In contrast, a study in Switzerland demonstrated that poultry was the most frequently A. baumannii -contaminated type of meat (45.7% of 94 samples); however, none of them were carbapenem resistant. 27 Meat is suspected to be a potential source of MDR A. baumannii , presumably resulting from faecal contamination.…”

Background Vietnam and Southeast Asia are hotspots for antimicrobial resistance; however, little is known on the prevalence of carriage of carbapenem resistance in non-hospitalized humans and in animals. Carbapenem-resistant Enterobacteriaceae (CRE), particularly Escherichia coli (CREC) and Klebsiella pneumoniae (CRKP) and also Acinetobacter baumannii (CRAB) are emerging threats worldwide. Methods We investigated healthy humans (n = 652), chickens (n = 237), ducks (n = 150) and pigs (n = 143) in 400 small-scale farms in the Mekong Delta of Vietnam. Samples (rectal swabs, faecal swabs) were investigated for carriage of CRE/CRAB and were further characterized phenotypically and genotypically. Results In the Mekong Delta of Vietnam, the prevalence of CRE isolates in human rectal swabs was 0.6%, including 4 CREC and 1 CRKP. One pig was infected with CREC (prevalence 0.7%). CRAB was isolated from chickens (n = 4) (prevalence 2.1%) and one duck (prevalence 0.7%). CRKP was isolated from a human who was also colonized with CREC. The CRKP strain (ST16), from an 80 year-old person with pneumonia under antimicrobial treatment, genetically clustered with clinical strains isolated in a hospital outbreak in southern Vietnam. The prevalence of CRE was higher among humans that had used antimicrobials within 90 days of the sampling date than those had not (4.2% versus 0.2%) (P = 0.005). All CRE/CRAB strains were MDR, although they were susceptible to colistin and neomycin. The carbapenemase genes identified in study strains were blaNDM and blaOXA. Conclusions The finding of a CRKP strain clustering with previous hospital outbreak raises concerns about potential transmission of carbapenem-resistant organisms from hospital to community settings or vice-versa.

“…Rare researches have been conducted in this field. Aksari et al [27] reported that the prevalence of A. baumannii in animal species' raw meat was 20.10%. They showed that A. baumannii isolates harbored the higher prevalence of resistance toward azithromycin (66.6%), gentamicin (87.1%), erythromycin (74.3%), tetracycline (79.4%), trimethoprim (56.4%), ciprofloxacin (58.9%), and rifampin (51.2%), which was relatively similar to our findings.…”

The First Report of the Antimicrobial Resistance of Acinetobacter baumannii Isolates from Seafood Samples

A cinetobacterbaumannii is a newly-launched bacterium responsible for rare cases of diarrhea and foodborne diseases. This survey was performed to study the prevalence and antimicrobial resistance of A. baumannii isolates recovered from fish, shrimp, and lobster. Five-hundred seafood samples were collected and cultured for isolation of A. baumannii. A. baumannii isolates were identified by biochemical tests and further confirmed by the PCR. The antimicrobial resistance of isolates was studied using disk diffusion test. Twenty-eight out of 500 (5.6%) seafood samples were contaminated with A. baumannii. Fish had the highest prevalence of A. baumannii (10%), while lobster had the lowest (2.5%). A. baumannii isolates harbored the highest incidence of resistance toward tetracycline (75%), gentamicin (71.4%), ciprofloxacin (64.2%), trimethoprim (57.1%), streptomycin (53.5%), and erythromycin (50%) antimicrobial agents. The lowest incidence of resistance was obtained against chloramphenicol (3.5%) and imipenem (7.1%) antimicrobial agents. This is the first report of isolation and identification and antimicrobial resistance pattern of A. baumannii in seafood samples globally. The role of seafood samples as reservoirs of antimicrobial-resistant A. baumannii was determined. Complete cooking of seafood and prevention from their consumption in raw form can diminish the risk of A. baumannii foodborne diseases.
