Abstract
The One Health approach of antimicrobial resistance highlighted the role of the aquatic environment as a reservoir and dissemination source of resistance genes and resistant bacteria, especially due to anthropogenic activities. Resistance to extended-spectrum cephalosporins (ESC) conferred by extended-spectrum beta-lactamases (ESBLs) in E. coli has been proposed as the major marker of the AMR burden in cross-sectoral approaches. In this study, we investigated wastewater, surface water and seawater that are subjected to official water quality monitoring in Monastir, Tunisia. While all but one sample were declared compliant according to the official tests, ESC-resistant bacteria were detected in 31 (19.1 %) samples. Thirty-nine isolates, coming from urban, industrial and surface water in Monastir, were collected and characterized using antibiograms and whole-genome sequencing. These isolates were identified as 27 Escherichia coli (69.3 %) belonging to 13 STs, 10 Klebsiella pneumoniae (25.6 %) belonging to six STs, and two Citrobacter freundii (5.1 %). We observed the persistence and dissemination of clones over time and in different sampling sites, and no typically human-associated pathogens could be identified apart from one ST131. All isolates presented a blaCTX-M gene - blaCTX-M-15 (n = 22) and blaCTX-M-55 (n = 8) being the most frequent variants - which were identified on plasmids (n = 20) or on the chromosome (n = 19). In conclusion, we observed ESC resistance in rather ubiquitous bacteria that are capable of surviving in the water environment. This suggests that including the total coliform count and the ESBL count as determined by bacterial growth on selective plates in the official monitoring would greatly improve water quality control in Tunisia.

Abstract
OBJECTIVES Wild birds are vectors of antimicrobial resistance. Birds living in close contact with humans or other animals, like feral pigeons (Columba livia), might be especially prone to acquire resistance genes such as those encoding extended-spectrum beta-lactamases (ESBLs) and carbapenemases. METHODS Cloacal samples (n = 206) of free-living feral pigeons (C. livia) were collected in Sousse and Monastir, Tunisia. Antimicrobial susceptibility profiles were determined by disc-diffusion, and resistant isolates were short- and long-read whole-genome sequenced. Sequence analysis was performed using tools of the Centre for Genomic Epidemiology, and Phylogenetic analysis was performed based on the core-genome MLST. RESULTS Fourteen (14/206, 6.8%) pigeons harboured Enterobacterales resistant to last-generations cephalosporins, of which 10 were CTX-M-15- or CTX-M-27-producers, while two (1.0%) carried a VIM-2-producing Pseudomonas putida. Positive pigeons lived on four different livestock farms. Three STs (ST206, ST5584, ST8149) were identified among E. coli, of which ST5584 and ST8149 were found in two different farms. Genetic diversity was also observed in Enterobacter cloacae and P. putida isolates. The blaCTX-M-27 genes were chromosomally encoded, while the blaCTX-M-15 genes were carried on highly similar IncF/F-:A-:B53 plasmids. The blaVIM-2 gene was located on a class 1 integron co-harbouring several resistance genes. CONCLUSION Pigeons living on livestock farms carried clinically important resistance genes encoding ESBLs and carbapenemases. Our results evidenced that both clonal (ST8149 and ST5584) and plasmidic (IncF/F-:A-:B53) transfers played a role in the spread of resistance genes among pigeons. Further studies are needed to identify factors favouring the transfer and persistence of resistance genes within the pigeon communities.

Abstract
Carbapenem-resistant Acinetobacter baumannii (CRAB) strains can cause severe and difficult-to-treat infections in patients with compromised general health. CRAB strains disseminate rapidly in nosocomial settings by patient-to-patient contact, through medical devices and inanimate reservoirs. The occurrence of CRAB in patients residing in the intensive care units (ICUs) of the Sahloul University hospital in Sousse, Tunisia is high. The objective of the current study was to determine whether the surfaces of items present in five ICU wards and the medical personnel there operating could serve as reservoirs for CRAB strains. Furthermore, CRAB isolates from patients residing in the ICUs during the sampling campaign were analyzed for genome comparison with isolates from the ICUs environment. Overall, 206 items were screened for CRAB presence and 27 (14%) were contaminated with a CRAB isolate. The items were located in several areas of three ICUs. Eight of the 54 (15%) screened people working in the wards were colonized by CRAB on the hands. Patients residing in the ICUs were infected with CRAB strains sharing extensive genomic similarity with strains recovered in the nosocomial environment. The strains belonged to three sub-clades of the internationally disseminated clone (ST2). A clone emerging in the Mediterranean basin (ST85) was detected as well. The strains were OXA-23 or NDM-1 producers and were also pan-aminoglycoside resistant due to the presence of the armA gene. Hygiene measures are urgent to be implemented in the Sahloul hospital to avoid further spread of difficult-to-treat CRAB strains and preserve health of patients and personnel operating in the ICU wards.

Abstract
European starlings are widespread migratory birds that have already been described as carrying bacteria resistant to extended-spectrum cephalosporins (ESC-R). These birds are well known in Tunisia because they spend the wintertime in this country and are hunted for human consumption. The goal of our study was to estimate the proportion of ESC-R in these birds and to characterize the collected isolates using whole-genome sequencing. Results showed that 21.5% (42/200) of the birds carried either an extended-spectrum beta-lactamase (ESBL) or an acquired AmpC gene. Diverse bla CTX-M genes were responsible for the ESBL phenotype, bla CTX-M-14 being the most prevalent, while only bla CMY-2 and one bla CMY-62 were found in AmpC-positive isolates. Likewise, different genetic determinants carried these resistance genes, including IncHI2, and IncF plasmids for bla CTX-M genes and IncI1 plasmids for bla CMY-2 genes. Three chromosomally encoded bla CTX-M-15 genes were also identified. Surprisingly, species identification revealed a large proportion (32.7%) of Escherichia marmotae isolates. This species is phenotypically indistinguishable from Escherichia coli and has obviously the same capacity to acquire ESC-R genes. Our data also strongly suggest that at least the IncHI2/pST3 plasmid can spread equally between E. coli and E. marmotae. Given the potential transmission routes between humans and animals, either by direct contact with dejections or through meat preparation, it is important to closely monitor antimicrobial resistance in European starlings in Tunisia and to set up further studies to identify the sources of contamination of these birds. IMPORTANCE The One Health concept highlighted knowledge gaps in the understanding of the transmission routes of resistant bacteria. A major interest was shown in wild migratory birds since they might spread resistant bacteria over long distances. Our study brings further evidence that wild birds, even though they are not directly submitted to antibiotic treatments, can be heavily contaminated by resistant bacteria. Our results identified numerous combinations of resistance genes, genetic supports, and bacterial clones that can spread vertically or horizontally and maintain a high level of resistance in the bird population. Some of these determinants are widespread in humans or animals (IncHI2/pST3 plasmids and pandemic clones), while some others are less frequent (atypical IncI1 plasmid and minor clones). Consequently, it is essential to be aware of the risks of transmission and to take all necessary measures to prevent the proportions of resistant isolates from increasing uncontrollably.

Abstract
Resistance to extended-spectrum cephalosporins (ESC) and carbapenems in Enterobacterales is a major issue in public health. Carbapenem resistance in particular is associated with increased morbidity and mortality. Moreover, such resistance is often co-harbored with resistance to non-beta-lactam antibiotics, and pathogens quickly become multi-drug-resistant (MDR). Only a few studies have been published on AMR in Libyan hospitals, but all reported worrisome results. Here, we studied 54 MDR isolates that were collected from 49 patients at the Tripoli University Hospital between 2019 and 2021. They were characterized using phenotypic methods, PCR and PFGE, and a sub-set of isolates were short- and long-read whole-genome sequenced. The results showed the frequent occurrence of Klebsiella pneumoniae (49/54), among which several high-risk clones were responsible for the spread of resistance, namely, ST11, ST17, ST101 and ST147. ESC and carbapenem resistance was due to a wide variety of enzymes (CTX-M, OXA-48, NDM, KPC), with their corresponding genes carried by different plasmids, including IncF-IncHI2 and IncF-IncR hybrids. This study highlights that implementation of infection prevention, control and surveillance measures are needed in Libya to fight against AMR.

Abstract
The gut microbiota is currently recognized as an important factor influencing the host's metabolism, immune and central nervous systems. Determination of the composition of the gut microbiota of healthy subjects is therefore necessary to establish a baseline for the detection of alterations in the microbiota under pathological conditions. So far, most studies describing the gut microbiota have been performed in populations from Asia, North America and Europe whereas populations from Africa have been overlooked. Here, we present the first characterization of the intestinal microbiota in healthy Tunisian adults using 16S rRNA gene sequencing. We further compare the gut microbiota composition based on gender and BMI. Our results showed that the Tunisian gut microbiota is dominated by the phyla Firmicutes and Bacteroidota in accordance with studies from western countries. However, some specificities have been identified, including a higher proportion of Firmicutes in males and higher proportions of Atopobiaceae, and Peptostreptococcaceae in Tunisian overweight individuals. Moreover, we were able to identify bacterial species differently represented between males and females and between normal weight and overweight individuals. These results constitute an important baseline that can be used to identify the dysbiosis associated with the main diseases affecting the Tunisian population.

Abstract
Aquaculture is a rapidly expanding sector in which it is important to monitor the occurrence of multi-drug resistant (MDR) bacteria. The presence of extended-spectrum β-lactamase (ESBL-) or carbapenemase-producing Enterobacterales is a commonly used indicator of the resistance burden in a given sector. In this study, 641 pieces of farmed fish (sea bream and sea bass), as well as 1075 Mediterranean clams, were analyzed. All ESBL- and carbapenemase-producing Enterobacterales collected were whole-genome sequenced. The proportion of ESBL-producing Enterobacterales was 1.4% in fish and 1.6% in clams, carried by Escherichia coli (n = 23) and Klebsiella pneumoniae (n = 4). The ESBL phenotype was exclusively due to the presence of blaCTX-M genes, the most frequent one being blaCTX-M-15. The blaCTX-M-1 gene was also identified in six E. coli, among which four were carried by IncI1/pST3 plasmids, possibly betraying an animal origin. Carbapenemases were absent in fish but identified in two K. pneumoniae isolates from clams (blaNDM-1 and blaOXA-48). Several sequence types (STs) identified were associated with human MDR clones such as E. coli ST131 and ST617, or K. pneumoniae ST307 and ST147. Our results might indicate that bacteria from hospital or farm effluents can reach the open sea and contaminate seafood and fish that are living or raised nearby. Therefore, monitoring the quality of water discharged to the sea and the presence of MDR bacteria in seafood is mandatory to ensure the quality of fishery products.

Abstract
Abstract
Objectives
To evaluate 30-day safety and efficacy of dual layered mesh covered carotid stent systems (DLS) for carotid artery stenting (CAS) in the clinical practice.
Background
When compared to carotid endarterectomy CAS has been associated to an higher rate of post procedural neurologic events; these could be related to plaque's debris prolapsing through stent's mesh. Consequently, the need for increased plaque coverage has resulted in the development of DLS.
Methods
From January 2017 to June 2019 a physician-initiated, prospective, multispecialty, registry enrolled 733 consecutive patients undergoing CAS using the CGuard Embolic Prevention System (EPS) in 20 centres. Primary endpoint was the stroke up to 30 days; secondary endpoints were the technical and procedural success; external carotid artery (ECA) occlusion; in-hospital and 30 days transient ischemic attack (TIA), acute myocardial infarction (AMI) and death rates.
Results
Symptoms were present in 131 patients (17.87%). An embolic protection device (EPD) was used in 731 patients (99.72%). Procedural success was 100%, technical success was obtained in all but one patient (99.86%), who died in-hospital due to a haemorrhagic stroke. Six TIAs, 2 minor strokes, and 1 AMI occurred during in-hospital stay, ECA occlusion was evident in 8 patients (1.09%). Between hospital discharge and 30-day, 2 TIAs, 1 minor stroke and 3 AMIs occurred. Therefore, the stroke rate at 30 days was 0.13.
Conclusion
This real-world registry suggests that use of CGuard EPS in clinical practice is safe and associated to a minimal occurrence of adverse neurological events up to 30 days follow up.

Abstract
Abstract
Background
Small sized clinical studies evaluating one year outcomes of CAS performed with two available DLS, Roadsaver® (RS) and CGuard® (CG), have been published.
Purpose
To evaluate one year safety and efficacy of dual layered mesh covered carotid stent systems (DLS) for carotid artery stenting (CAS).
Methods
We performed an individual patient-level meta-analysis including studies enrolling more than 100 CAS with DLS. Primary endpoint was the death and stroke rate; secondary endpoints were restenosis and in-stent thrombosis rates at one year.
Results
Patients were divided in two groups according to DLS (RS N=250; CG N=306). At one year, 11 patients died (1.97%), 7 patients in the group RS (2.8%) and 4 patients in the CG one (1.31%), 10 strokes occurred, 4 in the group RS (1.6%) and 6 in the CG one (1.96%). Overall death and stroke rate was 3.77% (N=21), 11 events in the group RS (4.4%) and 10 in the CG group (3.27%). Symptomatic status was the only predictor of death and or stroke.
At one year restenosis occurred in 12 patients (2.1%), 10 in the group RS (4%) and 2 in the CG one (0.65%) (p=0.007). In stent thrombosis occurred in 1 patient (0.18%) of the group CG (0.32%). RS use was the only independent restenosis predictor.
Conclusions
This study suggests that DLS use for CAS is associated to a low one year death and stroke rate and specific DLS stent use could affect restenosis rate.

Abstract
OBJECTIVES The aim of this study was to elucidate the molecular features of genes, plasmids and clones of OXA-48-like producingKlebsiella pneumoniae isolates recovered in Sahloul Hospital (Sousse, Tunisia) in the period 2012-2014. METHODS In vitro antimicrobial susceptibility testing, S1 nuclease pulsed-field gel electrophoresis (S1-PFGE), Southern blotting and PCR-based replicon typing (PBRT) were performed. Extended-spectrum β-lactamase (ESBL) and carbapenemases genes were detected by PCR and sequencing. The clonality of isolates was assessed by PFGE and multilocus sequence typing (MLST). RESULTS Klebsiella pneumoniae accounted for 26.8% (1095/4083) of clinical Enterobacterales isolates identified during 2012-2014, of which 21.9% (240/1095) were resistant to carbapenems, mostly harbouring blaOXA-48-like genes (196/240; 81.7%). Plasmid analysis showed that blaOXA-204 and blaOXA-48 were mostly carried by IncA/C and IncL plasmids, respectively. The current data highlight the dominance of two ST101 and ST147 lineages spreading OXA-48 and OXA-204, respectively, through successive clonal spreads at this hospital. In addition, a large diversity of other K. pneumoniae lineages was also identified, such as ST15, ST36 and ST525 spreading OXA-48 as well as ST340, ST2032, ST301, ST199 and ST1561 spreading OXA-48 or OXA-204, constituting a reservoir of possible dominant clones in the future. CONCLUSION This study reports the full molecular characterisation of carbapenem resistance in K. pneumoniae and the predominance of a few clones responsible for the dissemination of OXA-48 and OXA-204 enzymes in a Tunisian hospital.

Abstract
Objectives: The whole-genome sequence (WGS) of Klebsiella pneumoniae KP3771 isolate was characterized. This strain was recovered from the urine sample of an 80-year-old man hospitalized in an intensive care unit of the University Hospital Tahar Sfar in Tunisia. Materials and Methods: WGS using a MiSeq platform was used. The assembled genome was subjected to several software analyses. Results: K. pneumoniae KP3771 was resistant to all antibiotics but colistin and tigecycline. WGS analysis found 18 transmissible genes encoding resistance markers, including blaNDM-1 and blaCTX-M-15 genes, which were carried by four plasmids belonging to the Inc Ib, IIk, and R groups. Three families of genes encoding virulence factors were detected, including adhesins (fimH, fimA, fimB, fimC, mrkD, Kpn, and ycfM), siderophores (enterobactin, aerobactin, and yersiniabactin siderophores), and protectin/invasin (traT). The strain was assigned to the sequence type 147. Conclusions: This study describes the genome of a carbapenemase-producing K. pneumoniae clinical isolate recovered in Tunisia. Bacteria WGS has become the reference technology to address epidemiological issues; this high level of information is particularly well suited to enrich epidemiological workflows' output.

Abstract
Acinetobacter baumannii is an opportunistic pathogen in healthcare facilities responsible for nosocomial infections mostly in immunocompromised patients. Colistin resistance is increasingly reported worldwide in A. baumannii. Here we describe the in vivo selection of colistin and rifampicin resistance in carbapenem-resistant A. baumannii. Antimicrobial susceptibility testing, plasmid analysis and whole-genome sequencing (WGS) were performed to fully characterise the resistome of two clinical isolates (AbS1 and AbS2) selected during treatment. Clinical isolate AbS1 remained susceptible to colistin, rifampicin and tigecycline, whilst AbS2 was susceptible only to tigecycline. PCR analysis revealed the presence of a blaOXA-23-like carbapenemase gene. Kieser extraction revealed an ca. 74 kb plasmid harbouring blaOXA-23. WGS revealed genomes of 3.8 Mbp in size with a G + C content of 38.9%, and both belonged to ST281 according to the Oxford MLST scheme and ST641 according to the Institut Pasteur scheme. The resistome was also composed of naturally occurring β-lactamases, i.e. ADC-25 cephalosporinase and OXA-82 oxacillinase, aminoglycoside resistance genes [aac(3)-Ia, aadA1 and aph(3')-VIa (aphA6)], and mutations in DNA gyrases explaining fluoroquinolone resistance. Single nucleotide polymorphism analysis revealed that both isolates were identical except for a 30-nucleotide duplication within the pmrB gene and a point mutation in the rpoB gene resulting in colistin and rifampicin resistance, respectively. This study highlights the genomic plasticity of A. baumannii under antibiotic pressure. The 10-amino acid duplication in PmrB affects colistin susceptibility by regulating lipopolysaccharide modification through the PmrAB two-component system. These findings provide further information on the molecular mechanisms leading to colistin resistance in A. baumannii.

Abstract
We report a high prevalence of MCR-1 and CTX-M-1-producing Escherichia coli in three Tunisian chicken farms. Chickens were imported from France or derived from French imported chicks. The same IncHI2-type plasmid reported to carry those genes in cattle in France and in a food sample in Portugal was found in Tunisian chickens of French origin. This suggests a significant impact of food animal trade on the spread of mcr-1-mediated colistin resistance in Europe.

Abstract
Molecular features of the first carbapenem-resistant Klebsiella pneumoniae isolates (KP1 and KP2) from the University Hospital Tahar Sfar, Tunisia, were investigated. Antimicrobial susceptibility testing, multilocus sequence typing, S1 nuclease pulsed-field gel electrophoresis, Southern blot, and polymerase chain reaction (PCR)-based replicon typing were performed. Extended-spectrum β-lactamases and carbapenemase genes were detected by PCR and sequencing. Both isolates were multidrug resistant. KP1 was of sequence type (ST) ST101 and exhibited blaCTX-M-15 and blaTEM-1 on an untypeable plasmid and blaOXA-48 on an IncL/M plasmid. KP2 was genetically unrelated to KP1 (ST147) and harbored an IncA/C plasmid carrying blaCMY-4 and the blaOXA-48 derivative gene: blaOXA-204. This study reports the second case worldwide of an OXA-204-producing K. pneumoniae isolate from the same country, however, in a different genetic background.

Abstract
According to the World Health Organization, every year, 5 million peoples die for stroke and another 5 million are permanently disabled. Although there are many causes of acute stroke, a common treatable cause of acute stroke is atheromatous narrowing at the carotid bifurcation. Carotid endarterectomy is still the standard of car, even if carotid artery stenting (CAS) has become an effective, less invasive alterantive. Unfortunately, CAS procedure is not yet perfect; regardless the use of an embolic protection device (EPD), percutaneous treatment has been correlated with a risk of cerebral ischemic events related to distal embolization. The objective of the IRON-Guard Registry is to evaluate the clinical outcome of treatment by means of stenting with the C-Guard (InspireMD, Boston, MA, USA) in subjects requiring CAS due to significant extracranial carotid artery stenosis with a physician-initiated, Italian, prospective, multicenter, single-arm study. A total of 200 enrolled subjects divided over different centers are planned to be enrolled. CAS will performed by implanting of C-Guard stent. Procedure will be performed according to the physician's standard of care. Standard procedures will be followed based on the Instructions for Use, for the C-Guard device of Inspire. The primary endpoint of this study is the 30-day rate of major adverse events (MAE), defined as the cumulative incidence of any periprocedural (≤30 days postprocedure) death, stroke or myocardial infarction. Secondary endpoints are rate of late ipsilateral stroke (31 through 365 days), system technical success, device malfunctions, major adverse events (MAEs), serious device-related and procedure-related adverse events, target lesion revascularization, and in-stent restenosis rates.

Abstract
This study investigated the molecular features of extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae from hospital- and community-acquired (HA/CA) infections in the region of Mahdia, Tunisia. Among 336 K. pneumoniae isolates recovered from both clinical contexts between July 2009 and December 2011, 49 and 15 were ESBL producers and originated from clinical and community sources, respectively. All isolates produced the CTX-M-15 enzyme. As shown by Southern blot on S1 nuclease treatment followed by pulsed-field gel electrophoresis (PFGE) gels, the blaCTX-M-15 gene was carried on IncFII (n=4), IncFIIk (n=25), IncL/M (n=4), IncK (n=1), or untypeable (n=15) plasmids in HA isolates. In CA isolates, the blaCTX-M-15 gene was carried on IncFIIk (n=6), IncFII (n=1), IncHI1 (n=1), or untypeable (n=7) plasmids. In all, 23 and 11 PFGE types were found among the HA and CA isolates. Multilocus sequence typing on representative isolates shows diverse sequence types (STs), such as ST307, ST101, ST39, ST4, ST140, ST15, and ST307 in HA isolates and ST101, ST664, and ST323 in CA isolates. This study is the first comprehensive report of ESBL plasmids in K. pneumoniae from HA and CA infections in Tunisia.

Abstract
Extended-spectrum β-lactamases (ESBL) are widespread enzymes in animals, and the risk of transmission of ESBL genes to humans has become a major issue. In Tunisia, recent data showed a high prevalence of ESBL-producing Escherichia coli isolates in healthy animals, mostly in chickens. In this study, we report the first data on ESBL in diseased Tunisian animals (chickens and cattle), highlighting a major difference in ESBL prevalence in the infectious versus noninfectious E. coli flora. Interestingly, the only ESBL producer was an ST10 E. coli from a cattle, and not from chicken. Moreover, this E. coli isolate harbored the bla(CTX-M-15) gene on an F2:A-:B- plasmid, a combination frequently found in humans. This plasmid was also highly similar to a bla(CTX-M-15) F2:A-:B- plasmid recently reported in cattle in France. Altogether, this study is also the first report of the bla(CTX-M-15) gene in food animals in Tunisia, and, to our best knowledge, the first report of an ESBL producer in cattle in Africa. Since this plasmid was recognized in cattle in France and worldwide in humans, the question of its origin in Tunisian cattle is open. The detection of ESBL producers in milk in Tunisia may also constitute a risk of ESBL transmission from animals to humans through food consumption.

Abstract
BACKGROUND Studies of Glanzmann thrombasthenia (GT)-causing mutations has generated invaluable information on the formation and function of integrin αIIbβ(3). OBJECTIVE To characterize the mutation in four siblings of an Israeli Arab family affected by GT, and to analyze the relationships between the mutant protein structure and its function using artificial mutations. METHODS AND RESULTS Sequencing disclosed a new A97G transversion in the αIIb gene predicting Asn2Asp substitution at blade 1 of the β-propeller. Alignment with other integrin α subunits revealed that Asn2 is highly conserved. No surface expression of αIIbβ(3) was found in patients' platelets and baby hamster kidney (BHK) cells transfected with mutated αIIb and WT β(3). Although the αIIbβ(3) was formed, the mutation impaired its intracellular trafficking. Molecular dynamics simulations and modeling of the αIIbβ(3) crystal indicated that the Asn2Asp mutation disrupts a hydrogen bond between Asn2 and Leu366 of a calcium binding domain in blade 6, thereby impairing calcium binding that is essential for intracellular trafficking of αIIbβ(3). Substitution of Asn2 to uncharged Ala or Gln partially decreased αIIbβ(3) surface expression, while substitution by negatively or positively charged residues completely abolished surface expression. Unlike αIIbβ(3), αVβ(3) harboring the Asn2Asp mutation was surface expressed by transfected BHK cells, which is consistent with the known lower sensitivity of αVβ(3) to calcium chelation compared with αIIbβ(3). CONCLUSION The new GT causing mutation highlights the importance of calcium binding domains in the β-propeller for intracellular trafficking of αIIbβ(3). The mechanism by which the mutation exerts its deleterious effect was elucidated by molecular dynamics.

Abstract
Extended-spectrum beta-lactamases (ESBLs) in Pseudomonas aeruginosa are increasingly reported worldwide. In our study, a total of 70 clinical isolates of multidrug-resistant P. aeruginosa were studied. Isoelectric focusing electrophoresis, PCR, and PCR product sequencing were designed to characterize the contained ESBLs. The Double Disk Synergy Test in Cloxacillin (250 microg/ml)-containing Mueller-Hinton agar plates with a 20 mm distance between disks was the most reliable ESBL-screening method. Seven out of 70 multidrug-resistant P. aeruginosa clinical isolates were positive for ESBL and have the bla(SHV-2a) ESBL gene. The bla(SHV-2a)-positive isolates were clonally related according to Enterobacterial Repetetive Intergenic Consensus-PCR (ERIC-PCR) results. The bla(SHV-2a) gene was found to be chromosomally located, and the flanking IS26 sequence in the immediate upstream region of the bla(SHV-2a) gene was detected in all SHV-2a-producing isolates. This is the first report of SHV-2a-producing P. aeruginosa isolates from Tunisia.

Abstract
BACKGROUND In an acute care setting, diuretics are often prescribed to maintain or increase urine output in patients presenting with acute kidney injury (AKI). The rationale behind giving diuretics is that they may protect the kidney from ischemic injury by maintaining a nonoliguric state. There have been many studies both supporting and criticizing diuretic use in AKI for improving overall patient outcomes. METHODS A systematic review of the literature was conducted to evaluate the role of diuretics including osmotics, loop diuretics, and nesiritide in modifying AKI. RESULTS There was no evidence to suggest that the use of loop diuretics in AKI reduces mortality, the need for dialysis, the number of dialysis sessions, or length of Intensive Care Unit/hospital stay or that it increases the recovery of renal function. There is no benefit for the use of mannitol as an osmotic diuretic over hydration in rhabdomyolysis. In contrast, mannitol was found to cause more harm and to induce nephropathy. Nesiritide did not improve renal function in patients with decompensated heart failure and mild chronic renal insufficiency. Nesiritide may be effective in the prevention of AKI when applied in lower doses for a prolonged period of time in patients with mild to moderate renal insufficiency. CONCLUSIONS Diuretics have been shown to be ineffective in the prevention of AKI or for improving outcomes once AKI occurs. At best, diuretics can help decrease symptoms of pulmonary edema secondary to volume overload.

Abstract
Ninety-nine carbapenem-resistant Acinetobacter baumannii isolates were obtained from patients hospitalized between October 2005 and January 2007 at the University Hospital Sahloul, Sousse, Tunisia. Thirteen of those isolates produced the carbapenem-hydrolyzing oxacillinase OXA-23. All the OXA-23-positive isolates were clonally related, and the bla(OXA-23) gene was found to be chromosomally located and associated with an upstream-located insertion sequence ISAba1. This study further highlights the worldwide emergence of OXA-23-producing A. baumannii isolates.

Abstract
OBJECTIVE to characterize epidemiological and clinical features related to the multi-drug Acinetobacter baumannii infections in the university hospital Sahloul in Tunisia. MATERIAL AND METHODS retrospective study including twenty-four imipenem resistant Acinetobacter baumannii isolated from twenty patients hospitalized in different wards of the hospital. Study of clinical features related to the infection by multi-drug Acinetobacter baumannii, bacterial identification by classical identification scheme, antibiotic susceptibilities were determined by the disk diffusion method; genotyping was performed by arbitrarily-primed PCR. RESULTS the most incriminated ward was the intensive care unit with a high prevalence of septicaemia. All studied strains were multi-drug to all beta-lactams tested. Genotyping has shown the clonality of studied strains. Features incriminated in the acquisition of infection were essentially immunodeficiency, invasive manoeuvring and antibiotherapy. CONCLUSION multidrug Acinetobacter baumannii is increasingly isolated in our hospital. Rational use of antibiotics and rigorous application of hygienic rules could contribute to limit dissemination of such strains.
