Abstract
Stenotrophomonas maltophilia is an opportunistic pathogen, often associated with nosocomial infections. Ten S. maltophilia were isolated from clinical samples during the period January 2021 and June 2022. Eight (80%) patients had cancer as a background disease and 2 patients had coronavirus disease 2019. A fatal outcome was recorded in 4 cases (40% of patients). All the isolates were susceptible to minocycline and levofloxacin. Trimethoprim/sulfamethoxazole and ceftazidime resistance rates were 20% and 40% respectively. Eight different patterns were observed by Pulsed-Field Gel Electrophoresis, only two isolates being clonally identical. The isolation of S. maltophilia in clinical settings requires the implementation of infection prevention measures.

Abstract
Staphylococcus lugdunensis is a coagulase-negative-staphylococci (CoNS) that lately has gained special attention in public health as a human pathogen and also as a bacteriocin-producer bacteria. In this study, we characterized 56 S. lugdunensis isolates recovered from human samples in two Spanish hospitals. Antimicrobial susceptibility testing was performed and antimicrobial resistance and virulence genotypes were determined. Antimicrobial activity (AA) production was evaluated by the spot-on-lawn method against 37 indicator bacteria, including multidrug-resistant (MDR) isolates, and the presence of the lugD gene coding for lugdunin bacteriocin was analyzed by PCR. The antibiotic resistance detected was as follows (% resistance/genes detected): penicillin (44.6%/blaZ), oxacillin (1.8%/mecA on SCCmec-V), erythromycin-clindamycin inducible (7.1%/erm(C), msrA), tetracycline (5.3%/tetK), gentamicin and/or tobramycin (3.6%/ant(4′)-Ia, acc(6′)-aph(2″)), and fosfomycin (21.4%). A MDR phenotype was detected in 5% of isolates. Twenty-one of the S. lugdunensis isolates showed susceptibility to all 20 antibiotics tested (37.5%). The screening for AA revealed 23 antimicrobial producer (AP) isolates with relevant inhibition against coagulase-positive-staphylococci (CoPS), including both methicillin-susceptible and –resistant S. aureus. The lugD gene was detected in 84% of the 56 S. lugdunensis isolates. All of the AP S. lugdunensis isolates (n = 23) carried the lugD gene and it was also detected in 24 of the non-AP isolates, suggesting different gene expression levels. One of the AP isolates stood out due to its high antimicrobial activity against more than 70% of the indicator bacteria tested, so it will be further characterized at genomic and proteomic level.

Abstract
Introduction: The emergence of extended-spectrum β-lactamases (ESBLs)-producing Escherichia coli clones are a public health concern worldwide. Scarce information does exist about the spread of ESBLs-producing E. coli in pediatric patients from developing countries.
Methodology: E. coli strains were analyzed by multilocus-sequence-typing, pulsed-field-gel-electrophoresis and phylogenetic group. The antimicrobial-resistance genes were detected by PCR, and plasmid content by the PCR-based replicon-typing. Horizontal transfer was tested by conjugation and the location of the blaCTX-M-15 gene by Southern blot hybridization.
Results: Thirty-two cefotaxime-resistant E. coli were recovered. Eleven of them were ESBL-producing isolates, which were well characterized and ascribed to seven sequence types and five phylogroups. The ESBL CTX-M-15 was the most prevalent enzyme (9 of 11). Plasmids of variable sizes (40-220 kb) were visualized, and the incompatibility (Inc) group FIB plasmid-replicon was detected in the ESBL strains and transferred by conjugation in 45.45% of them.
Plasmid-borne toxin-antitoxin systems were the most frequently detected systems, strongly associated to IncF plasmids. The CTX-M-15-encoding gene was located on IncFIB plasmids.
Conclusions: Even though a small number of ESBL-producing strains was recovered, we evidenced that IncFIB plasmids carry the blaCTX-M-15 gene, highlighting the role of IncF-type plasmids in facilitating the spread and maintenance of ESBL-encoding genes, which further favors the rapid increase of the antimicrobial resistance dissemination in disease-causing E. coli strains in pediatric patients.

Abstract
This study aimed at determining the mechanisms of linezolid resistance and the molecular characteristics of clinical Staphylococcus aureus (n = 2) and coagulase-negative staphylococci (n = 15) isolates obtained from four Spanish hospitals. The detection of linezolid resistance mechanisms (mutations and acquisition of resistance genes) was performed by PCR/sequencing. The antimicrobial resistance and virulence profile was determined, and the isolates were typed by different molecular techniques. Moreover, the genetic environment of the cfr gene was determined by whole-genome sequencing. The cfr gene was detected in one methicillin-resistant S. aureus (MRSA) that also displayed the amino acid change Val118Ala in the ribosomal protein L4. The second S. aureus isolate was methicillin susceptible and showed different alterations in the ribosomal protein L4. All remaining linezolid-resistant Staphylococcus epidermidis (n = 14) and Staphylococcus hominis isolates (n = 1) showed the mutation G2576T (n = 14) or C2534T (n = 1) in the 23S rRNA. Moreover, different amino acid changes were detected in the ribosomal proteins L3 and L4 in S. epidermidis isolates. All S. epidermidis isolates belonged to the multilocus sequence type ST2. Linezolid-resistant staphylococci (LRS) showed a multiresistance phenotype, including methicillin resistance that was detected in all isolates but one, and was mediated by the mecA gene. The cfr gene in the MRSA isolate was located together with the fexA gene on a conjugative 38,864 bp plasmid. Linezolid- and methicillin-resistant S. epidermidis ST2 showing mutations in the 23S rRNA and in the ribosomal proteins L3 and L4 are spread among Spanish hospitals, whereas LRS carrying acquired linezolid resistance genes are rarely detected.

Abstract
The increased incidence of antibiotic-resistant Enterobacteriaceae is a public health problem worldwide. The aim of this study was to analyze the potential role of wild birds, given their capacity of migrating over long distances, in the spreading of carbapenemase, extended-spectrum β-lactamase (ESBL), and acquired-AmpC beta-lactamase-producing Enterobacteriaceae in the environment. Fecal and pellet samples were recovered from 150 wild birds in seven Tunisian regions and were inoculated in MacConkey-agar plates for Enterobacteriaceae recovery (one isolate/animal). Ninety-nine isolates were obtained and acquired resistance mechanisms were characterized in the five detected imipenem-resistant and/or cefotaxime-resistant isolates, by PCR and sequencing. The following ESBL, carbapenemase, and acquired-AmpC beta-lactamase genes were detected: blaCTX-M-15 (two Escherichia fergusonii and one Klebsiella oxytoca isolates), blaKPC-2 (one K. oxytoca), blaKPC-3 (one E. fergusonii), blaACT-36, and blaACC-2 (two K. oxytoca, four E. fergusonii, and two E. coli). The IncFIIs, IncF, IncFIB, IncK, IncP, and IncX replicons were detected among these beta-lactamase Enterobacteriaceae producers. The blaKPC-2, tetA, sul3, qnrB, and cmlA determinants were co-transferred by conjugation from K. oxytoca strain to E. coli J153, in association with IncK and IncF replicons. Our results support the implication of wild birds as a biological vector for carbapenemase, ESBL, and acquired-AmpC-producing Enterobacteriaceae.

Abstract
Extended-spectrum beta-lactamase (ESBL)- and carbapenemase (CP)-producing Klebsiella pneumoniae isolates are a public health concern at clinical level, mainly in Southern European countries. However, there are scarce data on the role of companion animals in the emergence of resistance to clinically relevant antibiotics. Therefore, our study aimed to determine the presence of K. pneumoniae with relevant beta-lactamases in fecal samples from healthy dogs (kennel and house dogs) and sick dogs in seven different hospitals in Portugal. Fecal samples from 125 healthy dogs and 231 sick dogs (one per animal) were collected during April-August 2017. Samples were screened on MacConkey agar supplemented with meropenem, and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) was used for K. pneumoniae identification. Genotypic detection of ESBLs or CPs was carried out by PCR/sequencing. Moreover, the presence of other antimicrobial resistance genes and multilocus sequence typing was tested by PCR/sequencing. K. pneumoniae isolates were obtained from 16 tested samples (4.4%), and 3 of them were ertapenem and/or meropenem intermediate/resistant (all of them imipenem susceptible and negative for CP genes). Fifteen K. pneumoniae isolates were ESBL producers, and they carried the following beta-lactamase genes: blaCTX-M-15+blaSHV-28 (four isolates, in three cases associated with blaTEM-1), blaCTX-M-15+blaSHV-1 (five isolates, associated with TEM-1 in three cases), and blaSHV-28+blaTEM-1 (six isolates). Three ESBL-producing K. pneumoniae isolates of different origins and beta-lactamase genotypes (CTX-M-15+SHV-28, CTX-M-15+SHV-28+TEM-1, or SHV-28+TEM-1) belonged to the lineage ST307, and one isolate was identified as ST15 (CTX-M-15+SHV-1). These findings highlight that dogs are frequent carriers of ESBL-producing K. pneumonia isolates, harboring mostly genes encoding CTX-M-15 or SHV-28, associated in some cases with the high-risk clones ST307 and ST15.

Abstract
The aim of this study was to determine the carriage rate of coagulase-positive staphylococci (CoPS) in wild birds and to characterize recovered isolates. Tracheal samples from 324 wild birds, obtained in different Spanish regions during 2015-2016, were screened for CoPS carriage. The antimicrobial resistance profile and the virulence gene content were investigated. Molecular typing was performed by spa, agr, MLST, SCCmec, and S. delphini group classification. CoPS were recovered from 26 samples of wild birds (8.3%), and 27 isolates were further characterized. Two CoPS species were detected: S. aureus (n = 15; eight cinereous vultures and seven magpies) and S. delphini (n = 12; 11 cinereous vultures and one red kite). Thirteen S. aureus were methicillin-resistant (MRSA) and the remaining two strains were methicillin-susceptible (MSSA). Twelve MRSA were mecC-positive, typed as t843-ST1583/ST1945/ST1581/ST1571 (n = 11) and t1535-ST1945 (n = 1) (all of clonal-complex CC130); they were susceptible to the non-β-lactams tested. The remaining MRSA strain carried the mecA gene, was typed as t011-ST398-CC398-agrI-SCCmec-V, and showed a multiresistance phenotype. MSSA isolates were ascribed to lineages ST97-CC97 and ST425-CC425. All S. aureus lacked the studied virulence genes (lukS/F-PV, tst, eta, etb, and etd), and the IEC type E (with scn and sak genes) was detected in four mecC-positive and one MSSA isolates. S. delphini strains were methicillin-susceptible but showed resistance to at least one of the antimicrobials tested, with high penicillin (75%, with blaZ gene) and tetracycline [58%, with tet(K)± tet(L)] resistance rates. All S. delphini isolates presented the virulence genes lukS-I, siet, and se-int, and four carried the clindamycin-resistance lnu(A) gene.

Abstract
In this study, we investigated the airborne dissemination of bacteria from the inside of two very different pork farms (an intensively confined farm and an open-range farm) to the immediate environment. Samples were taken from the slurry, from the air inside the farms (area 0), and from their immediate surroundings at a distance of 50, 100, and 150 m in four directions (north, south, east, and west). A control sample in the air of a zone far away from human or animal activity was also taken. Identification of isolates was made by means of the matrix-assisted laser desorption-ionization time of flight system. A total of 1,063 isolates were obtained, of which a mere 7 came from the air of the control area. Staphylococci, enterococci, and Enterobacteriaceae were selectively targeted for isolation and represented 48.6, 27.2, and 21.6% of the isolates, respectively. The species identified from the air of surrounding areas ( Enterococcus faecalis, Enterococcus hirae, and Staphylococcus arlettae, mainly) were also present inside the farms studied. The results suggest that air is involved in bacterial dissemination, and pork farms should be considered a potential source of foodborne bacteria that might contaminate surrounding areas, including vegetable orchards. Wind direction appears as a factor involved in bacterial dispersion through the air, but its effect may be conditioned by existing vegetation and orographic conditions.

Abstract
Twenty-six lactose non-fermenting, oxidase, urease and citrate-positive Gram-negative rods, isolated from broiler chickens, pigs and cattle at slaughter, were subjected to the matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry and 16S rDNA sequencing for identification. Susceptibility to 14 antimicrobials was determined by the disc diffusion method. Ochrobactrum isolates resistant to third-generation cephalosporins were PCR-screened for the presence of the Ochrobactrum anthropi ampC gene (blaOCH). A 547-bp internal segment of blaOCH in the Ochrobactrum spp isolates was amplified with a newly designed primer set, and a phylogenetic reconstruction based on the complete amino acid sequence of blaOCH obtained from nine Ochrobactrum strains in our collection and 20 O. anthropi available in the GenBank was undertaken. All the Ochrobactrum isolates were resistant to the expanded-spectrum beta-lactams and streptomycin. None of the isolates was resistant to imipenem while 41.7% to 50.0% of them were resistant to fluoroquinolones. The blaOCH gene was detected in 16 (66.7%) and 20 (83.3%) of the 24 Ochrobactrum isolates (O. intermedium/O. tritici species), using primers designed for O. anthropi and the newly designed primer set, respectively. Six blaOCH variants grouped into two divergent clusters were identified. This is the first report of the complete nucleotide sequence of the blaOCH gene in non-antropi Ochrobactrum species.

Abstract
Gastrointestinal colonisation by carbapenem-resistant Acinetobacter baumannii (CRAB) is a critical step before nosocomial infection. This study evaluated CRAB intestinal carriage in patients admitted to a Tunisian ICU and determined the antimicrobial resistance mechanisms involved. From December 2014 to February 2015, all 63 patients admitted to the ICU were screened for rectal CRAB colonisation upon admission and once weekly thereafter. ICU patients who acquired a CRAB nosocomial infection were also included. β-Lactamases and associated resistance genes were screened by PCR sequencing, and molecular typing was performed by PFGE and MLST. The CRAB faecal carriage rate at admission was 4.8% (3/63). The CRAB acquisition rate during ICU stay was analysed in 39 of the remaining 60 patients and the rate of acquired CRAB faecal carriage was 15.4% (6/39); 4 patients also showed an ICU-acquired CRAB infection (one patient was a faecal carrier and suffered infection). Overall, 13 CRAB isolates were collected from 12 patients, of which 11 isolates showed resistance to all antibiotics tested except colistin. blaOXA-23 and blaNDM-1 were detected in 11 and 2 isolates, respectively. All OXA-23-producing strains carried armA, tetB, sul1 and catB, and some of them carried aph(3')-VIa, blaTEM-1, aph(3')-Ia and ant(2'')-Ia. The blaNDM-1-positive isolates harboured aph(3')-VIa and catB. Three PFGE patterns and two STs were identified [ST195 (n = 11), ST1089 (n = 2, NDM-1-positive)]. Whether imported or acquired during ICU stay, CRAB colonisation is a major risk factor for the occurrence of serious nosocomial infection. Systematic screening of faecal carriage is mandatory to prevent their spread.

Abstract
Our study aimed to investigate colistin resistance and the mechanisms involved in a collection of 35 extended-spectrum beta-lactamase (ESBL) and 13 CMY-2-producing E. coli strains which were previously recovered from chicken gut microbiota in Tunisia, as well as to determine the genetic location of mcr genes. Forty-eight ESBL and CMY-2-producing E. coli strains were obtained from 137 fecal samples of healthy chickens during 2013. These strains were tested for colistin resistance by the broth microdilution method, and screened for mcr-1 and mcr-2 genes by PCR. Two of these strains were colistin-resistant (MIC = 8 mg/L). Both harbored the mcr-1 gene, were CMY-2 producers, and were additionally resistant to tetracycline, ciprofloxacin, chloramphenicol, gentamicin, tobramycin and trimethoprim-sulfamethoxazole. They shared phylogroup A, the same pulsed-field gel electrophoresis (PFGE)-pattern, and were typed as ST2197. In both strains, ISApl1 and pap2 were detected upstream and downstream of mcr-1 gene, respectively. The analysis of the two mcr-1-positive strains and their transconjugants by PCR-based replicon typing and S1-PFGE, demonstrated that mcr-1 gene is linked to an IncP plasmid (~242 kb), and blaCMY-2 to an IncI1 plasmid (97 kb). The occurrence of E. coli harboring mcr-1 gene among intestinal microbiota in poultry and its location on a conjugative plasmid could represent a risk for public health. The evolution of this type of resistant microorganisms should be evaluated in the future.

Abstract
Objectives This study aimed at characterizing 23 Escherichia coli isolates from various sources and their respective bla SHV-12 -carrying plasmids and sequencing one of these plasmids completely. Methods Isolates were typed by XbaI-PFGE, MLST and PCR-based phylotyping. Transformed bla SHV-12 -carrying plasmids were examined by replicon typing, S1-nuclease, conjugation, EcoRI-HindIII-BamHI digests and plasmid MLST. Co-located resistance genes and integrons as well as the bla SHV-12 genetic environment were analysed by PCR and sequencing. One IncI1 plasmid was sequenced completely using HiSeq 2500 and gap closure by PCRs and Sanger sequencing. Results Among the 23 SHV-12-positive E. coli , some isolates from different sources showed the same characteristics: ST23/phylogroup A (human, dog, livestock), ST57/D (wild bird, chicken meat) and ST117/D (chicken meat, chicken). All bla SHV-12 genes were horizontally transferable via 30-120 kb plasmids of incompatibility groups IncI1 ( n = 17), IncK ( n = 3), IncF ( n = 1), IncX3 ( n = 1) and a non-typeable plasmid. IncK plasmids, indistinguishable in size and restriction patterns, were found in isolates from different sources (ST57/D, meat; ST131/B2, meat; ST57/B1, dog). The IncI1- bla SHV-12 -carrying plasmids were mostly assigned to plasmid ST (pST) 26 and pST3. Three plasmids showed novel pSTs (pST214, pST215). The majority of the IncI1 transformants exhibited resistance to β-lactams, chloramphenicol and streptomycin (in relation with a class 1 integron containing an estX - psp - aadA2 - cmlA1 - aadA1 - qacI gene cassette array), and to tetracycline. A novel bla SHV-12 environment was detected and whole plasmid sequencing revealed a Tn 21 -derived- bla SHV12 -ΔTn 1721 resistance complex. Conclusions Results from this study suggest that the dissemination of bla SHV-12 genes occurs by vertical (clonal) and horizontal transfer, the latter mainly mediated through IncI1 multidrug-resistance plasmids.

Abstract
Wild boars are worldwide distributed mammals which population is increasing in many regions, like the Iberian Peninsula, leading to an increased exposition to humans. They are considered reservoirs of different zoonotic pathogens and have been postulated as potential vectors of antimicrobial-resistant (AMR) bacteria. This study aimed to determine the prevalence of antimicrobial resistance and phylogenetic distribution of Escherichia coli from wild boar feces. Antimicrobial resistance and integron content was genetically characterized and E. coli of B2 phylogroup was further analyzed by molecular typing and virulence genotyping. The prevalence of AMR E. coli was low, with only 7.5% of isolates being resistant against at least one antimicrobial, mainly ampicillin, tetracycline and/or sulfonamide. An unexpected elevated rate of B2 phylogroup (47.5%) was identified, most of them showing unrelated pulsed-field-gel-electrophoresis patterns. ST131/B2 (fimH 22 sublineage), ST28/B2, ST1170/B2, ST681/B2 and ST625/B2 clones, previously described in extraintestinal infections in humans, were detected in B2 isolates, and carried one or more genes associated with extraintestinal pathogenic E. coli (ExPEC). This study demonstrated a low prevalence of antimicrobial resistance in E. coli from wild boars, although they are not exempt of AMR bacteria, and a predominance of genetically diverse B2 phylogroup, including isolates carrying ExPEC which may contribute to the spread of virulence determinants among different ecosystems.

Abstract
Shiga toxin-producing E. coli (STEC) and enteropathogenic E. coli (EPEC) strains are food-borne pathogens associated with acute diarrhea. Haemolytic-uremic syndrome (HUS) is often a complication of STEC infection. In order to examine the occurrence, serotypes, virulence and antimicrobial-resistance profiles of STEC and EPEC in wildlife, 326 faecal E. coli strains from 304 clinically healthy animals were analyzed. For this approach stx1, stx2 and eae genes, as well as accessory virulence determinants (ehx, hlyA, saa, tia, bfp, subAB) were PCR-screened and sequenced. Serotyping was performed employing all available O (O1-O185) and H (H1-H56) antisera. Genetic diversity was analyzed by XbaI-PFGE and phylotyping. Thirteen STEC (4.3%) and 10 EPEC (3.3%) were identified among 12 deer, 3 mouflon, 6 wild boars and 2 birds. Nine STEC showed seropathotypes B (O145:[H28]) and C (O22:H8, O128:[H2]) associated with HUS, and D (O110:H28, O146:H21, O146:[H28], ONT:H8) associated with human diarrhea. Although most isolates harbored stx2b and stx1c variants, stx2a and stx1a (related with severe disease) were also detected. Additionally, the eae gene was present in one stx2a-positive O145:[H28] STEC from a deer and 11 STEC harbored subAB genes (mainly the subAB2 variant). EPEC isolates showed 7 different intimin variants (β1, β2, γ1, ε1, ζ1, ι1-A, κ). Interestingly, the O49:[H10] eae-κ EPEC isolated from a wild boar was bfpA-positive showing a combination of serotype/virulence profile previously detected among human clinical tEPEC. Based on present results, wild ruminants, wild boars and to a lesser extent birds would be carriers of potentially pathogenic STEC and EPEC strains.

Abstract
BACKGROUND AND OBJECTIVES Disk diffusion testing, known as antibiogram, is widely applied in microbiology to determine the antimicrobial susceptibility of microorganisms. The measurement of the diameter of the zone of growth inhibition of microorganisms around the antimicrobial disks in the antibiogram is frequently performed manually by specialists using a ruler. This is a time-consuming and error-prone task that might be simplified using automated or semi-automated inhibition zone readers. However, most readers are usually expensive instruments with embedded software that require significant changes in laboratory design and workflow. METHODS Based on the workflow employed by specialists to determine the antimicrobial susceptibility of microorganisms, we have designed a software tool that, from images of disk diffusion tests, semi-automatises the process. Standard computer vision techniques are employed to achieve such an automatisation. RESULTS We present AntibiogramJ, a user-friendly and open-source software tool to semi-automatically determine, measure and categorise inhibition zones of images from disk diffusion tests. AntibiogramJ is implemented in Java and deals with images captured with any device that incorporates a camera, including digital cameras and mobile phones. The fully automatic procedure of AntibiogramJ for measuring inhibition zones achieves an overall agreement of 87% with an expert microbiologist; moreover, AntibiogramJ includes features to easily detect when the automatic reading is not correct and fix it manually to obtain the correct result. CONCLUSIONS AntibiogramJ is a user-friendly, platform-independent, open-source, and free tool that, up to the best of our knowledge, is the most complete software tool for antibiogram analysis without requiring any investment in new equipment or changes in the laboratory.

Abstract
BACKGROUND This study describes the phenotypic and genotypic characteristics of 78 genetically different Escherichia coli recovered from air and exudate samples of a dairy cattle farm and its surroundings in Spain, in order to gain insight into the flow of antimicrobial resistance through the environment and food supply. RESULTS Antimicrobial resistance was detected in 21.8% of the 78 E. coli isolates analyzed (resistance for at least one of the 14 agents tested). The highest resistance rates were recorded for ampicillin, nalidixic acid, trimethoprim/sulfamethoxazole and tetracycline. The resistance genes detected were as follows (antibiotic (number of resistant strains), gene (number of strains)): ampicillin (9), blaTEM-1 (6); tetracycline (15), tet(A) (7), tet(B) (4), tet(A) + tet(B) (1); chloramphenicol (5), cmlA (2), floR (2); trimethoprim/sulfamethoxazole (10), sul2 (4), sul1 (3), sul3 (2), sul1 + sul2 (1); gentamicin-tobramycin (1), ant(2″) (1). About 14% of strains showed a multidrug-resistant phenotype and, of them, seven strains carried class 1 integrons containing predominantly the dfrA1-aadA1 array. One multidrug-resistant strain was found in both inside and outside air, suggesting that the airborne spread of multidrug-resistant bacteria from the animal housing facilities to the surroundings is feasible. CONCLUSIONS This study gives a genetic background of the antimicrobial resistance problem in a dairy cattle farm and shows that air can act as a source for dissemination of antimicrobial-resistant bacteria. © 2016 Society of Chemical Industry.

Abstract
To get a better insight into the role of birds as reservoirs of extended-spectrum β-lactamase (ESBL) and plasmidic AmpC β-lactamase (pAmpC) Escherichia coli producers, 100 fecal samples belonging to 15 different wild avian species from Northern Spain were analyzed. Cefotaxime-resistant (CTXR) E. coli isolates were identified in 16 of the 100 tested birds, which corresponded to 9 animal species (Gyps fulvus-griffon vulture, Larus michahellis-yellow-legged gull, Milvus migrans-black kite, Milvus milvus-red kite, Ciconia ciconia-white stork, Sturnus unicolor-spotless starling, Aquila chrysaetos-golden eagle, Cuculus canorus-common cuckoo, Tyto alba-barn owl). Fifteen isolates harbored ESBL or pAmpC-encoding genes (number of isolates): bla SHV-12 (9), bla CTX-M-1 (3), bla CTX-M-14 (2), and bla CMY-2 (1). The last CTXR isolate presented a -42-point-mutation in the chromosomal ampC promoter. Eleven out of 15 ESBL/pAmpC E. coli isolates were multiresistant (most common resistance phenotype: β-lactams-quinolones-tetracycline-sulfamethoxazole/trimethoprim). A plasmid-mediated quinolone resistance determinant (qnrS1) was identified in one E. coli from a barn owl. High genetic diversity was observed among ESBL/pAmpC E. coli isolates, with 12 different sequence types (STs), including several strains of STs frequently detected among human clinical isolates (ST38/D, ST131/B2, ST155/B1, ST10/A). The ST131 isolate belonged to the emergent ciprofloxacin-resistant H30R subclone. This study reveals a high percentage of bird as carriers of ESBL/pAmpC E. coli isolates in Spain, highlighting the elevated rate among storks, kites, and vultures. Wild birds can contribute to the global spread of ESBL/pAmpC-producing E. coli in natural ecosystems.

Abstract
The presence of extended-spectrum beta-lactamase and plasmid-mediated AmpC beta-lactamase producing Enterobacteriaceae (ESBL-Eb and pAmpC-Eb, respectively) was analyzed in 57 wastewater and 57 surface-water samples in Tunisia. Twenty-four of the 57 wastewater samples (42.1%) and one of the 57 surface-water samples (1.7%, a river that received effluents of a wastewater-treatment-plant) contained ESBL-Eb or pAmpC-Eb; one ESBL/pAmpC-Eb per positive sample was further characterized. Beta-lactamase genes detected were as follows: blaCTX-M-1 (10 Escherichia coli),blaCTX-M-15 (eight E. coli, one Klebsiella pneumoniae, one Citrobacter freundii), blaCTX-M-14 (one E. coli) and blaCMY-2 (four E. coli). The blaTEM-1, blaOXA-1 or blaSHV-1 genes were also found in 72% of these isolates. The ISEcp1, orf477 or IS903 sequences were found upstream or downstream of blaCTX-M genes. Class 1 integrons were present in 16 of the 25 ESBL-Eb/pAmpC-Eb strains (64%), and contained five different gene-cassette arrays. Most of the strains (76%) showed a multiresistant phenotype and qnr genes were identified in four strains. Molecular typing of ESBL/CMY-2-producing E. coli isolates showed 23 different PFGE-patterns and 15 different sequence-types (ST10, ST46, ST48, ST58, ST69, ST101, ST117, ST131, ST141, ST288, ST359, ST399, ST405, ST617, and the new ST4530); these strains were ascribed to phylogroups A (11 isolates), B1 (3 isolates), D (6 isolates) and B2 (3 isolates). From one to five plasmids were detected in each strain (size from 30kb to >240kb) and ESBL or pAmpC genes were transferred by conjugation in 69.5% of the E. coli strains. In conclusion, ESBL-Eb and pAmpC-Eb strains are frequently detected in wastewater samples and they might be a source for dissemination in other environments with repercussion in public health.

Abstract
The spread of extended spectrum β-lactamases (ESBL) and plasmid mediated AmpC β-lactamases (pAmpC) was evaluated in Escherichia coli strains collected from the intestinal microbiota of healthy children in Tunisia. The carriage rate of CTXRE. coli was 6.6% (7 of 105 samples) and one strain/sample was further characterized (7 isolates). These isolates harbored blaCTX-M-1 (n = 4), blaCTX-M-15 (n = 2), and blaCMY-2 gene (n = 1), which were usually located on FIB replicon type and carried class 1 integrons. The acc(6')-Ib-cr variant was identified in one isolate that harbored blaCTX-M-15. CTXRE. coli isolates were genetically unrelated and belonged to B1 (n = 3/ST155/ST398/ST58), D (n = 2/ST117/ST493), B2 (n = 1/ST127), and A (n = 1/ST746) phylogroups. Strain virulence scores varied from 3 to 12, and frequently harbored the pathogenicity island PAI IV536. The intestinal tract of healthy children constitute an important reservoir of ESBL producing E. coli. Thus, improvement of hygiene measures mainly in the school environment and rational use of antibiotics would be of great help in preventing selection and diffusion of resistant strains from intestinal microbiota.

Abstract
One-hundred-nine samples of 18 different farms (49 of food-vegetables, 41 of soil and 19 of irrigation water) and 45 vegetable food samples of 13 markets were collected in Tunisia. These samples were inoculated in MacConkey agar plates supplemented with cefotaxime (2 μg/ml). ESBL-producing Enterobacteriaceae (ESBL-Eb) were detected in 10 of the 109 farm samples (vegetables, 8.2%; soil, 7.3%; water, 15.8%), and in 4 of 45 vegetables of markets (8.9%), recovering 15 ESBL-Eb. Isolates and ESBL genes detected were: Escherichia coli (n=8: 5 blaCTX-M-1, 2 blaCTX-M-15 and one blaCTX-M-14), Citrobacter freundii (n=4: 3 blaCTX-M-15 and one blaSHV-12), Enterobacter hormaechei (n=2: 2 blaCTX-M-15) and Klebsiella pneumoniae (n=1, blaCTX-M-15). The ISEcp1 sequence was found upstream of blaCTX-M genes in 13 of 14 strains (in three cases truncated by IS5), and orf477 or IS903 downstream. Class 1 integrons were detected in five strains and contained two gene cassette arrangements (dfrA17-aadA5 and aadA1). Most isolates tested showed a multiresistant phenotype. All blaCTX-M-15-positive strains carried the aac(6')-1b-cr gene, that affects to amikacin-tobramycin-kanamycin-ciprofloxacin. Five ESBL-Eb strains carried genes of the qnr family. The 8 ESBL-positive E. coli isolates were typed as: ST58/B1 (n=3) and ST117/D, ST131/B2, ST10/A, ST23/A, and the new ST3496/D (one strain, each). From 1-2 plasmids were detected in all ESBL-positive E. coli isolates (63-179 kb). The ESBL genes were transferred by conjugation in 4 blaCTX-M-1-positive E. coli strains, and transconjugants acquired a 97 kb IncI1 plasmid. ESBL-Eb isolates are frequently disseminated in vegetable farms and potentially could be transmitted to humans through the food chain.

Abstract
A collaborative work was carried out by the Spanish and Portuguese ISFG Working Group (GEP-ISFG) to estimate Y-STR mutation rates. Seventeen Y chromosome STR loci (DYS19, DYS385, DYS389I and II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635 [GATA C4], GATA H4, and GATA A10) were analyzed in a sample of 3,026 father/son pairs. Among 27,029 allele transfers, 54 mutations were observed, with an overall mutation rate across the 17 loci of 1.998 x 10(-3) (95% CI, 1.501 x 10(-3) to 2.606 x 10(-3)). With just one exception, all of the mutations were single-step, and they were observed only once per gametogenesis. Repeat gains were more frequent than losses, longer alleles were found to be more mutable, and the mutation rate seemed to increase with the father's age. Hum Mutat 26(6), 520-528, 2005.

Abstract
Over the last two decades, guided tissue regeneration has achieved significant advances in periodontal healing that confirm the efficacy of periodontal regeneration. Several types of barriers have been utilized to apply this principle to periodontal wound healing. The objective of this article is to review the literature and principles of guided periodontal tissue regeneration (GPTR) in the treatment of Class II furcation defects and to describe a surgical technique that utilizes the neighboring periosteum of the furcation lesion as a barrier for the clinical application of GPTR.

Abstract
One hundred infrabony pockets with one- and two-wall bony defects were treated for reattachment. Mucoperiosteal flaps were raised, the tooth surfaces were scaled and planed, and the defects curetted. Flaps were sutured tightly and the sites protected with a surgical dressing. Antibiotic coverage was used in each case. Pre- and postoperative measurements were taken by the same clinician from the cemento-enamel junction to the base of the pocket. In 56 defects cancellous bone from the same patient was placed in the defect, and in 44 defects the treatment consisted only of open curettage without bone grafts. The results showed a trend towards more favourable clinical results using bone grafts; especially in the two-wall bony defects.
