Abstract
Pseudomonas aeruginosa an opportunistic pathogen that causes infections in hospitals and has high morbidity and mortality rates. In addition, it is a widely distributed environmental bacterium that can colonise a variety of habitats. Although wild animals do not have access to antibiotics, antibacterial resistance in these animals has increasingly been reported worldwide. Although the presence of Klebsiella pneumoniae carbapenemase (KPC) is uncommon in P. aeruginosa, it has been increasingly reported. This study examined KPC-2-producing P. aeruginosa in wild animals. A total of 27 P. aeruginosa isolates were obtained from clinical cases treated at the Microbiology Laboratory of the Veterinary Hospital of UFMT, Brazil. P. aeruginosa and blaKPC-2 carbapenemase resistance genes were identified using PCR. Antimicrobial susceptibility of KPC-producing P. aeruginosa was evaluated using the disk diffusion method. The blaKPC-2 gene was detected in 40.7% of the isolates (11/27). The rates of antimicrobial resistance and intermediate sensitivity were as follows: piperacillin/tazobactam (44.4%), imipenem (29.6%), meropenem (51.8%), amikacin (77.8%), cefepime (85.2%), and ciprofloxacin (70.4%). Twelve isolates were classified as Multidrug-resistant (MDR). This study presents the first report of P. aeruginosa with the blaKPC-2 gene in wild animals in Brazil, highlighting the importance of molecular research on resistance genes in P. aeruginosa from a One-Health perspective.

Abstract
Background Antimicrobial resistance (AMR) is an emerging threat to global health security. Globally, an estimated 700,000 deaths are attributed to AMR annually. Annual deaths due to AMR are projected to reach 10 million by 2050 if current trends persist. Extended Spectrum β-Lactamases (ESBLs) have the ability to hydrolyse penicillins, cephalosporins up to the third generation, and monobactams, but not β-lactamase inhibitors such as clavulanic acid. ESBLs undergo continuous mutation, leading to the development of new enzymes with over 400 different ESBL variants described. This study aimed to detect selected CTX-M genes, SHV,and TEM genes in Extended Spectrum Beta-Lactamase producing Klebsiella pneumoniae and Pseudomonas aeruginosa in Jos, Nigeria. Methodology A total of 110, non-replicated isolates of Klebsiella pneumonia and 125 isolates of Pseudomonas aeruginosa were identified phenotypically from clinical specimens of patients at a tertiary hospital in Jos, North-central Nigeria. The isolates were screened for ESBL production using the disk diffusion method of the Clinical Laboratory Standard Institute (CLSI) breakpoints. Phenotypic confirmation of ESBL production was done using the double-disc synergy test. Multiplex PCR was used to detect ESBL genes. Results Fifty (45.5%) of the 110 isolates of Klebsiella pneumoniae and 9(7.2%) of the 125 isolates of Pseudomonas aeruginosa were ESBL-positive. Typing of 20 representative ESBL isolates (17 Klebsiella and 3 Pseudomonas spp) showed the presence ofblaCTX-M1, blaCTX-M9, and blaSHV genes in these isolates. All 20 (100%) isolates had the blaCTX-M1 gene. The blaSHV gene was detected in 16(80%) while CTX-M9 was detected in 6(30%) of the isolates studied. Conclusion The study showed that there is a high prevalence of ESBL genes among isolates ofKlebsiella pneumoniae and Pseudomonas aeruginosa in North-central Nigeria. This emphasizes the need for continuous surveillance and coordinated infection prevention and control to curtail its spread.

Abstract
BACKGROUND Pseudomonas aeruginosa bacteria are emerging causes of food spoilage and foodborne diseases. Raw meat of animal species may consider a reservoir of P. aeruginosa strains. OBJECTIVES The present survey was done to assess the prevalence, antibiotic resistance properties and distribution of virulence factors among the P. aeruginosa strains isolated from raw meat and carcass surface swab samples of animal species. METHODS Five hundred and fifty raw meat and carcass surface swab samples were collected from cattle and sheep species referred to as slaughterhouses. P. aeruginosa bacteria were identified using culture and biochemical tests. The pattern of antibiotic resistance was determined by disk diffusion. The distribution of virulence and antibiotic resistance genes was determined using polymerase chain reaction. RESULTS Forty-seven of 550 (8.54%) examined samples were contaminated with P. aeruginosa. The prevalence of P. aeruginosa in raw meat and carcass surface swab samples were 6.57 and 12%, respectively. P. aeruginosa isolates showed the maximum resistance rate toward penicillin (87.23%), ampicillin (85.10%), tetracycline (85.10%), gentamicin (65.95%) and trimethoprim (57.44%). The most commonly detected antibiotic resistance genes were BlaCTX-M (53.19%), blaDHA (42.55%) and blaTEM (27.65%). The most commonly detected virulence factors was ExoS (42.55%), algD (31.91%), lasA (31.91%), plcH (31.91%) and exoU (25.53%). CONCLUSIONS Meat and carcass surface swab samples may be sources of resistant and virulent P. aeruginosa, which pose a hygienic threat in their consumption. However, further investigations are required to identify additional epidemiological features of P. aeruginosa in meat and carcass surface samples.

Abstract
Resistant and virulent Pseudomonas aeruginosa (P. aeruginosa) bacteria are measured as the major cause of food spoilage and food-borne diseases. This survey assesses the prevalence, antibiotic resistance properties, and virulence factors distribution in P. aeruginosa bacteria isolated from meat and meat products. A total of 370 raw, frozen, and imported bovine meat samples and diverse types of meat product samples were collected from Alborz province, Iran. P. aeruginosa bacteria were identified by culture. Disk diffusion was used to assess the antibiotic resistance of bacteria. Furthermore, the PCR was used to assess the virulence and antibiotic resistance genes. Twenty nine out of 370 (7.83%) samples were contaminated with P. aeruginosa. Imported frozen bovine meat (20%) harbored the highest distribution, while sausage (2%) harbored the lowest. High resistance rates were observed toward ampicillin (89.65%), penicillin (86.20%), tetracycline (82.75%), cefoxitin (37.93%), gentamicin (34.48%), and clindamycin (31.03%). The most commonly detected antibiotic resistance genes were blaDHA (93.10%), blaCTX-M (83.65%), and blaSHV (48.27%). BlaDHA (93.10%), blaCTX-M (83.65%), and blaSHV (48.27%) were the most frequently detected resistance genes. The most commonly detected virulence genes were exoS (75.86%), lasA (68.96%), exoU (58.62%), lasB (51.72%), plcH (48.27%), and algD (44.82%). Meat and meat product samples may be sources of P. aeruginosa, which show an important threat to their consumption. Nevertheless, additional inquiries are obligatory to find supplementary epidemiological properties of P. aeruginosa in meat and meat product samples.

Abstract
Pseudomonas aeruginosa strains are potential pathogens that cause respiratory diseases in minks, and caused serious economic loss to mink breeding industry. In this study, we identified antimicrobial resistance and virulence genes in 125 P. aeruginosa isolates from mink in China from 2011 to 2020. The results showed at least one mutation in the gyrA (Thr83Val or Asp87Gly) and parC (Ser87 Leu) genes as well as single mutations in 56 isolates. At least 4-fold reductions in the fluoroquinolone minimum inhibitory concentration values were found when tested in the presence of PAβN in 23 isolates, while 44 isolates were positive for the extended spectrum β-lactamases and 15 antibiotic resistance genes were identified in this population with a prevalence between 1-32%, including qnrA, CTX-M-1G, ermB and C, cmlA, flor, catl, intl1, tetA, B, C, and D as well as sul1, 2, and 3 genes. Interestingly, one isolate carried ten resistance genes. Five virulence genes were detected, where exoS and algD were the most frequently detected (76.8%), which were followed by plcH (76%), lasB (73.6%), and pilB (31.2%). The isolates carrying the antibiotic resistance or virulence genes were genetically variable, suggesting a horizontal spread through the population. Hence, this study provides novel and important data on the resistance and pathogenicity of P. aeruginosa in farmed mink infections. These data provide important insights into the mechanism of fluoroquinolone resistance in P. aeruginosa, highlighting its usefulness in the treatment and control of P. aeruginosa infections in minks.

Abstract
Foods are essential vehicles in human exposure to antibiotic resistant bacteria which serve as reservoirs for resistance genes and a rising food safety concern. Antimicrobial resistance, including multidrug resistance (MDR), is an increasing problem globally and poses a serious concern to human health. This study was designed to synthesize data regarding the prevalence of MDR bacteria associated with foods and drinks sold within Nigeria in order to contribute to the existing findings in this area. A comprehensive literature search on the prevalence of multi-drug resistant bacteria associated with foods and drinks in Nigeria from 2015 to 2020 was conducted using three databases; PubMed, Science Direct and Scopus. After screening and selection, 26 out of 82 articles were used for the qualitative data synthesis. Of the total of one thousand three hundred and twenty-six MDR bacteria reportedly isolated in all twenty-six articles, the highest prevalence (660) was observed in drinks, including water, while the lowest (20) was observed in the article which combined results for both protein and vegetable-based foods. Escherichia sp. had the most frequency of occurrence, appearing as MDR bacteria in ten out of the twenty-six articles. Salmonella sp. appeared as MDR in seven out of the twenty-six articles included in this study, in all seven articles where it was reported, it had the highest percentage (85.4%) prevalence as MDR bacteria. Public health personnel need to ensure critical control during the production and handling of foods and drinks, as well as create more awareness on proper hygienic practices to combat the spread of MDR bacteria becoming a growing food safety issue (Zurfluh et al., 2019; Mesbah et al., 2017; Campos et al., 2019). Foods can be contaminated by different means, including exposure to irrigation water, manure, feces or soil with pathogenic bacteria. Foods can also become contaminated as they are harvested, handled after harvest or during processing if food safety standards are not correctly applied (Meshbah et al., 2017). Food-borne diseases caused by resistant organisms are one of the most important public health problems as they contribute to the risk of development of antibiotic resistance in the food production chain (Hehempour-Baltork et al., 2019). Apart from pathogenic bacteria causing foodborne diseases, foods that are raw or not processed following standard procedures can introduce several antibiotic-resistant bacteria (ARB) to consumers (Gekemidis et al., 2018). Antibiotic resistance, though harbored in non-pathogenic bacteria, can potentially be spread through horizontal gene transfer to other species including opportunistic pathogens that are present in the environment or after consumption of ARB-contaminated foods. When ARB-contaminated foods are consumed, the spread of antibiotic resistant genes may affect the gut microbiome thereby contributing to the pool of antibiotic-resistance genes (ARG) in the human gut (Gekemidis et al, 2018). MDR bacteria have been defined as bacteria that are resistant to at least one antimicrobial agent present in three or more antimicrobial classes (Sweeny et al., 2018). There has been an increase in drug resistance in pathogens isolated from food for human consumption with species of Escherichia coli and Salmonella enterica being considered among the most important pathogens due to their ability to effect zoonotic transfer of resistant genes (Canton et al., 2018; Maneilla-Becerra et al., 2019). However, other pathogens, such as Vibrio spp., some species of Aeromonas, spores of Clostridium botulinum type F, and Campylobacter, have been linked to food-borne diseases in humans who have consumed seafood or other animal foods (Maneilla-Becerra et al., 2019). Some other resistant bacteria associated with foods include Staphylococcus aureus, Listeria spp., and Shigella spp. (Maneilla-Becerra et al., 2019) This study was therefore designed to synthesize data (2015-2020) regarding the prevalence of MDR bacteria associated with foods and drinks sold within Nigeria in order to contribute to the existing findings in this area.

Abstract
Background
Multiple antibiotic-resistant (MAR) Pseudomonas aeruginosa (P. aeruginosa) plays a significant role in triggering nosocomial infection in clinical settings. While P. aeruginosa isolated from the environment is often regarded as non-pathogenic, the progressive development of antibiotic resistance necessitates exploring the MAR patterns and transposable genetic elements like plasmid in the isolates.
Results
Using ecfX gene-based PCR, 32 P. aeruginosa isolates among 48 soil samples collected from the industrial region have been confirmed. The antibiotic susceptibility pattern of those isolates revealed that 5 (15.63%) of them were resistant to a range of antibiotics, and they were categorized as MAR isolates. Nevertheless, all MAR isolates were found resistant to piperacillin and gentamicin, but none of them to ceftazidime, aztreonam, and ciprofloxacin. Moreover, the isolates were also showed resistance to amikacin (60%), tobramycin (80%), netilmicin (80%), imipenem (60%), doripenem (40%), meropenem (60%), and cefixime (40%). Furthermore, 60% of MAR isolates possessed double plasmids of 1000–2000 bp sizes which indicates the distribution of antibiotic resistance genes in MAR P. aeruginosa might be correlated with the presence of those plasmids. The MAR index’s high threshold values (> 0.20) implied that the isolates were from high-risk environmental sites where the presence of numerous antibiotic residues happened.
Conclusions
These findings highlighted the presence of multiple antibiotic resistance in P. aeruginosa of the industrial soil and a considerable prospect of transferring antibiotic resistance genes in the microbial community by plasmids. We recommend taking immediate stringent measures to prohibit the unnecessary and overuse of antibiotics in agricultural, industrial, or other purposes.

Abstract
AIMS This work aimed to determine the occurrence, virulence, antibiogram, carbapenem resistance genes and susceptibility to disinfectants of Pseudomonas aeruginosa isolated from animals, environment and workers in intensive farms. METHODS AND RESULTS A total of 610 samples from intensive beef cattle and sheep farms in Kafr El Sheikh Governorate, Egypt were screened for the presence of P. aeruginosa using bacteriological assays. The isolates were characterized by PCR and tested for susceptibility to antibiotics using disk diffusion method and disinfectants by quantitative suspension test. In all, 60 P. aeruginosa isolates were recovered in this study and all isolates harboured at least one of the virulence genes tested. Human P. aeruginosa isolates were highly resistant to cephalosporins, fluroquinolones, aminoglycosides, carbapenems and penicillins+β-lactamase inhibitors than non-human isolates. Colistin resistance was higher in non-human than human P. aeruginosa isolates, whereas low resistance to aztreonam was observed in non-human and human isolates. Carbapenem-resistant P. aeruginosa (CRPA) strains were recovered from workers (56.5%), sheep (8.3%) and cattle (8.3%). All CRPA harboured at least one of the carbapenem resistance genes tested and most of them showed multidrug resistance (MDR) or extensive drug resistance (XDR) phenotypes. Glutaraldehyde 1% and hydrogen peroxide 3% eliminated P. aeruginosa completely in the absence and presence of organic matter within short contact time compared with other disinfectants. CONCLUSIONS This study reported the occurrence of CRPA in animals and workers in intensive farms. Glutaraldehyde and hydrogen peroxide were the most effective disinfectants against P. aeruginosa. SIGNIFICANCE AND IMPACT OF THE STUDY The occurrence of CRPA in intensive livestock farms is a serious challenge that threatens animal and human health and increases the risk of P. aeruginosa infection in the community. Therefore, it is vital to control the spread of CRPA by banning or restricting the use of antibiotics and applying proper cleaning and disinfection protocols in livestock farms.

Abstract
Patient-derived isolates of the opportunistic pathogen Pseudomonas aeruginosa are frequently resistant to antibiotics due to the presence of sequence variants in resistance-associated genes. However, the frequency of antibiotic resistance and of resistance-associated sequence variants in environmental isolates of P. aeruginosa has not been well studied. Antimicrobial susceptibility testing (ciprofloxacin, ceftazidime, meropenem, tobramycin) of environmental (n=50) and cystic fibrosis (n=42) P. aeruginosa isolates was carried out. Following whole genome sequencing of all isolates, 25 resistance-associated genes were analysed for the presence of likely function-altering sequence variants. Environmental isolates were susceptible to all antibiotics with one exception, whereas patient-derived isolates had significant frequencies of resistance to each antibiotic and a greater number of likely resistance-associated genetic variants. These findings indicate that the natural environment does not act as a reservoir of antibiotic-resistant P. aeruginosa, supporting a model in which antibiotic susceptible environmental bacteria infect patients and develop resistance during infection.

Abstract
Background We investigate here the presence of multidrug-resistant bacteria isolated from stool samples of yellow-legged gulls and chickens (n = 136) in urban parks and beaches of Marseille, France. Bacterial isolation was performed on selective media, including MacConkey agar with ceftriaxone and LBJMR medium. Antibiotic resistance genes, including extended-spectrum β-lactamases (ESBL) (i.e. blaCTX-M, blaTEM and blaSHV), carbapenemases (blaKPC, blaVIM, blaNDM, blaOXA-23, blaOXA-24, blaOXA-48 and blaOXA-58) and colistin resistance genes (mcr-1 to mcr-5) were screened by real-time PCR and standard PCR and sequenced when found. Results Of the 136 stools samples collected, seven ESBL-producing Gram-negative bacteria (BGN) and 12 colistin-resistant Enterobacteriaceae were isolated. Among them, five ESBL-producing Escherichia coli and eight colistin-resistant Hafnia alvei strains were identified. Four blaTEM-1 genes were detected in yellow-legged gulls and chickens. Three CTX-M-15 genes were detected in yellow-legged gulls and pigeons, and one CTX-M-1 in a yellow-legged gull. No mcr-1 to mcr-5 gene were detected in colistin-resistant isolates. Genotyping of E. coli strains revealed four different sequence types already described in humans and animals and one new sequence type. Conclusions Urban birds, which are believed to have no contact with antibiotics appear as potential source of ESBL genes. Our findings highlight the important role of urban birds in the proliferation of multidrug-resistant bacteria and also the possible zoonotic transmission of such bacteria from wild birds to humans.

Abstract
INTRODUCTION Pseudomonas aeruginosa (member of ESKAPE group) is predominantly responsible for emerging nosocomial infections and poses serious health concern due to ever-increasing drug resistance trends. The current study investigates the prevalence of such highly resistant P. aeruginosa in major hospital settings and further characterizes and compares them for genetic heterogeneity. MATERIALS AND METHODS Samples of patients (n=108) with wound infections, bacteremia and burn injuries from major hospitals of Rawalpindi and Islamabad during 2017 to 2018 were collected for the present study. The samples were processed in the COMSATS Microbiology and Public Health lab and screened for the P. aeruginosa by routinely used biochemical tests, drug susceptibility tests and rapid molecular approaches. RESULTS The results suggested that most of the isolates (88/108) are indeed P. aeruginosa (81.4%) underpinning the need of its active surveillance in hospital settings. Further analysis suggested that 32 of these 88 microbes are multi-drug resistance (36.3%), 16 (18.1%) are extensively drug resistance and 4 (4.5%) are pan-drug resistance. Moreover, double disc synergistic test suggested that 16 (18.1%) are positive for metallo-β-lactamase production. Molecular screening confirmed that 2 (12.5%) and 3 (18.75%) of these 16 isolates are positive for VIM and NDM gene respectively while all the studied isolates were positive for AmpC β-lactamase. PAP17 isolate harbors both VIM and NDM genes. ERIC PCR profiling showed that majority of MDR bacteria fall in cluster II and III similarly XDR bacteria also fall in cluster II and III while PDR bacteria fall in cluster IV. CONCLUSION This study revealed that majority of the isolates are multi drug resistant MDR and extensively drug resistant (XDR). However, the presence of some pan drug resistant (PDR) isolates among such small sample size screened is of utmost concern. Molecular typing of extremely resistant P. aeruginosa revealed high genetic diversity. Therefore, we suggest that regular monitoring and surveillance of such highly resistant P. aeruginosa in hospital settings will help to control their transmission and hence reduce the disease burden.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15061284. [PMID: 29914203 PMCID: PMC6025306 DOI: 10.3390/ijerph15061284] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Revised: 06/14/2018] [Accepted: 06/14/2018] [Indexed: 02/05/2023]
Abstract
Antimicrobial resistance (AMR) has emerged as a global health threat, which has elicited a high-level political declaration at the United Nations General Assembly, 2016. In response, member countries agreed to pay greater attention to the surveillance and implementation of antimicrobial stewardship. The Nigeria Centre for Disease Control called for a review of AMR in Nigeria using a “One Health approach”. As anecdotal evidence suggests that food animal health and production rely heavily on antimicrobials, it becomes imperative to understand AMR trends in food animals and the environment. We reviewed previous studies to curate data and evaluate the contributions of food animals and the environment (2000⁻2016) to the AMR burden in Nigeria using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flowchart focused on three areas: Antimicrobial resistance, residues, and antiseptics studies. Only one of the 48 antimicrobial studies did not report multidrug resistance. At least 18 bacterial spp. were found to be resistant to various locally available antimicrobials. All 16 residue studies reported high levels of drug residues either in the form of prevalence or concentration above the recommended international limit. Fourteen different “resistotypes” were found in some commonly used antiseptics. High levels of residues and AMR were found in food animals destined for the human food chain. High levels of residues and antimicrobials discharged into environments sustain the AMR pool. These had evolved into potential public health challenges that need attention. These findings constitute public health threats for Nigeria’s teeming population and require attention.

Abstract
Antimicrobial agents are used in both veterinary and human medicine. The intensive use of antimicrobials in animals may promote the fixation of antimicrobial resistance genes in bacteria, which may be zoonotic or capable to transfer these genes to human-adapted pathogens or to human gut microbiota via direct contact, food or the environment. This review summarizes the current knowledge of the use of antimicrobial agents in animal health and explores the role of bacteria from animals as a pool of antimicrobial resistance genes for human bacteria. This review focused in relevant examples within the ESC(K)APE (Enterococcus faecium, Staphylococcus aureus, Clostridium difficile (Klebsiella pneumoniae), Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacteriaceae) group of bacterial pathogens that are the leading cause of nosocomial infections throughout the world.

Abstract
BACKGROUND The rapid increase of extended-spectrum beta-lactamase (ESBL) producing bacteria are a potential health hazard. Development of antimicrobial resistance in animal pathogens has serious implications for human health, especially when such strains could be transmitted to human. In this study, the antimicrobial resistance due to ESBL producing Pseudomonas aeruginosa in the camel meat was investigated. METHODS In this study meat samples from 200 healthy camels at two major abattoirs in Egypt (Cairo and Giza) were collected. Following culture on cetrimide agar, suspected P. aeruginosa colonies were confirmed with a Vitek 2 system (bioMe´rieux). P. aeruginosa isolates were phenotypically identified as ESBL by double disk synergy test. Additionally antimicrobial susceptibility testing of ESBL producing P. aeruginosa isolates were done against 11 antimicrobial drugs and carried out by disk diffusion method. The ESBL genotypes were determined by polymerase chain reaction according to the presence of the bla PER-1, bla CTX-M, bla SHV, and bla TEM. RESULTS Pseudomonas aeruginosa was isolated from 45 camel meat sample (22.5%). The total percentage of ESBL producing P. aeruginosa was 45% (21/45) from camel meat isolates. Antibiogram results revealed the highest resistance was for c, ceftriaxone and rifampicin followed by cefepime and aztreonam. The prevalence rates of β-lactamase genes were recorded (bla PER-1 28.5%, bla CTX-M 38%, bla SHV 33.3% and bla TEM 23.8%). CONCLUSIONS This study illustrates the presence of high rates of ESBL-P. aeruginosa in camels that represents an increasing alarming for the risk of transmission to human and opens the door for current and future antibiotics therapy failure. Livestock associated ESBL-P. aeruginosa is a growing disaster, therefore, attention has to be fully given to livestock associated ESBL-bacteria which try to find its way to human beings.
