Introduction to Clonal Group

Genetic analysis showed low heterogeneity with the identification of six clonal groups, three clusters with homology greater than 80% and seven distinct genotypes.

The clade A1 strains clustered into six clonal groups of highly similar isolates, three of which consisted entirely of isolates from a single patient.

Pseudomonas aeruginosa is an environmental bacterium and a nosocomial pathogen with clone C one of the most prevalent clonal groups.

Our data show common features with other European countries in relation to a prevalent clonal group (CC10), serotypes (O108:H39, O138:H10, O139:H1, O141:H4), high plasmid content within the isolates and mcr location, which would support global alternatives to the use of antibiotics in pigs.

We investigated the prevalence and dissemination of different clonal groups of S.

Moreover, we found that an IgG3 cluster from different clonal groups had the same IGHV, IGHJ and CDR3 sequences (IGHV4-4-CARLANTNQFYDSSSYLNAMDVW-IGHJ6).

The ST131 clonal group accounted for 17.

Only 1/17 EEP strains versus 12/17 non-EEP MDR strains belonged to the ST131 clonal group.

Finally, rep-PCR typing showed similar fingerprints with MLST, except for ST23, such that ST23 was discriminated in two clonal groups, suggesting the greater discriminatory power of rep-PCR.

Two clonal groups, CC45 and CC1041, caused 11 cases (42% of K.

MLST analysis revealed that ST340 (n = 8), a member of the worldwide existing high-risk epidemic clonal group 258 (CG258), was predominant.

Recognized epidemic clonal groups ST410, ST131 and ST744 were encountered.

Chester isolates belonging to one clonal group were causing repetitive outbreaks in Europe.

multocida are of the capsule type B and form one clonal grouping with isolates ST64, ST44, ST45, ST46, ST44, ST47 which isolated from cases of hemorrhagic septicemia of animals in Hungary, Burma, Sri Lanka, Pakistan and Spain.

We investigated the possibility of exploiting the increased transformability of hsd mutants by constructing a deletion mutation in hsdM in GAS strain 854, a clinical isolate representative of the globally dominant M1T1 clonal group.

coli clonal groups such as ST101 and ST167 are one of the main causes of E.

coli clonal group ST1193, the mutant variants of gyrA and parC were acquired not by a typical gradual, stepwise evolution but all at once.

MLSTs were diverse and did not comprise the 'traditional' KPC clonal group (CG) 258.

Objectives To examine the epidemiology of β-lactam resistance in 'clonal group 258' (CG258), a successful KPC clonal group, over 14 years.

Secondly, the antimicrobial resistance is able to be determined through identifying (i) the antimicrobial-resistant clonal groups based on the fingerprints of the clone, (ii) the shift peak of the modified antimicrobial drug, which is inactivated by the resistance determinant, (iii) the shift peak of the modified antimicrobial target, (iv) the peak specific for the antimicrobial determinant, and (v) the biomarkers that are coproduced proteins with AMR determinants.

Our results illustrate the presence and persistence of highly resistant clonal groups of enterotoxin-producing MRSA in meat samples.

Background The rapid emergence of multidrug-resistant Klebsiella pneumoniae (Kp) is largely driven by the spread of specific clonal groups (CG).

In particular, we notice the international diffusion of specific clonal group ST131.

coli ST131 is a major ExPEC clonal group worldwide with variable plasmid composition, and has an array of genes enabling antimicrobial resistance (AMR).

coli sequence type 131 (ST131) is a major ExPEC clonal group worldwide, with variable plasmid composition, and has an array of genes enabling antimicrobial resistance (AMR).

Here, we demonstrate the population structure of 485 STEC isolates in Australia, and show that several clonal groups (CGs) common to Australia were infrequently detected in a representative selection of contemporary STEC genomes from around the globe.

Several clonal groups of E.

These strains were associated with globally distributed clonal groups linked with confirmed foodborne listeriosis outbreak and sporadic cases.

Our study highlights the emerging challenges entailed in the WGS-powered epidemiological surveillance of globally distributed clonal groups.

These data add 25 new core genome sequence types and were clustered in 15 clonal groups, including 12 new clonal groups.

About 20 % of the isolate genotypes were grouped into 15 clonal groups.

Three clonal groups (cluster I, cluster II, and cluster III) were identified in these tet(A)-bearing isolates.

We identified 18 flavonoids differentially accumulated among the three clonal groups as potential selection biomarkers against R.

The clonal group 258 (CG258) is considered a high-risk CG and the K.

MLST analysis revealed that ST340 (n = 8), a member of the worldwide existing high-risk epidemic clonal group 258 (CG258), was predominant.

pneumoniae belonging to the genetically diverse, globally disseminated clonal group CG258.

Whole-genome sequencing analysis identified the international ST340 (clonal group CG258), and genes and mutations conferring resistance to β-lactams, aminoglycosides, macrolides, phenicols, fosfomycin, sulfonamides, tetracycline, trimethoprim, and fluoroquinolones.

In particular, we notice the international diffusion of specific clonal group ST131.

coli is a leading cause of healthcare-associated infections; clonal group ST131, which has expanded worldwide with notable increased severity of infections, is commonly resistant to extended-spectrum cephalosporins (ESC) and fluoroquinolones (FQ).

coli ST131 is a major ExPEC clonal group worldwide with variable plasmid composition, and has an array of genes enabling antimicrobial resistance (AMR).

coli sequence type 131 (ST131) is a major ExPEC clonal group worldwide, with variable plasmid composition, and has an array of genes enabling antimicrobial resistance (AMR).

A recent increase in the incidence of hypervirulent Klebsiella pneumoniae (hvKP) infections, especially those caused by a sublineage of the clonal group CG23 (CG23-I), is raising serious health concerns worldwide.

The clonal group CG23 comprises hypervirulent K.

It seems that clonal group 23 (CG23) is associated with liver abscess and CG11 related to various clinical sources.

The molecular genetic characteristic of the Klebsiella pneumoniae KP254 clinical strain belonging to clonal group 23, are given based on the genome-wide sequencing results.
