| Experiment for Molecule Alteration |
Southern blotting assay | |||
| Mechanism Description | An assay based on the utilization of degenerate primers that enable enzymatic amplification of an internal fragment of cat genes known to be present in gram-positive cocci was developed to identify the genes encoding chloramphenicol resistance in streptococci and enterococci. The functionality of this system was illustrated by the detection of cat genes belonging to four different hydridization classes represented by the staphylococcal genes catpC221, catpC194, catpSCS7, and the clostridial gene catP, and by the characterization of a new streptococcal cat gene designated catS. | |||

| Mechanism Description | However, little is known about CmR in staphylococcal species pathogenic to animals. Recently, CmR plasmids have been isolated from 'equine's. sciuri, 'canine' S. epidermidis, 'porcine' S. hyicus and 'canine' S. intermedius strains. All staphy- lococcal CmR plasmids encode a common resistance mechanism, namely an inducible Cm acetyltransferase (CAT). | |||

| Mechanism Description | The norA gene cloned from chromosomal DNA of quinolone-resistant Staphylococcus aureus Tk2566 conferred relatively high resistance to hydrophilic quinolones such as norfloxacin, enoxacin, ofloxacin, and ciprofloxacin, but only low or no resistance at all to hydrophobic ones such as nalidixic acid, oxolinic acid, and sparfloxacin in S. aureus and Escherichia coli. S. aureus SA113 (pTUS20) harboring a plasmid carrying the staphylococcal norA gene was 16 to 64 times more resistant to relatively hydrophilic quinolones. | |||

| Mechanism Description | Twelve mutational changes at 10 positions were identified, with 473Ala-Thr representing a new mutation site. New amino acid substitutions, 465Gln-Arg, 466Leu-Ser, 468Gln-Lys, and 477Ala-Thr in cluster I and 527Ile-Met and 529Ser-Leu in cluster II, were described, thereby emphasizing the high variability of these amino acid positions. Codon 481 was mutated on 32 separate occasions, which indicates a central role of this amino acid. All in vivo isolates that demonstrated two or three amino acid changes exhibited high-level resistance. Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

| Mechanism Description | Twelve mutational changes at 10 positions were identified, with 473Ala-Thr representing a new mutation site. New amino acid substitutions, 465Gln-Arg, 466Leu-Ser, 468Gln-Lys, and 477Ala-Thr in cluster I and 527Ile-Met and 529Ser-Leu in cluster II, were described, thereby emphasizing the high variability of these amino acid positions. Codon 481 was mutated on 32 separate occasions, which indicates a central role of this amino acid. All in vivo isolates that demonstrated two or three amino acid changes exhibited high-level resistance. Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

| Mechanism Description | Twelve mutational changes at 10 positions were identified, with 473Ala-Thr representing a new mutation site. New amino acid substitutions, 465Gln-Arg, 466Leu-Ser, 468Gln-Lys, and 477Ala-Thr in cluster I and 527Ile-Met and 529Ser-Leu in cluster II, were described, thereby emphasizing the high variability of these amino acid positions. Codon 481 was mutated on 32 separate occasions, which indicates a central role of this amino acid. All in vivo isolates that demonstrated two or three amino acid changes exhibited high-level resistance. Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

| Mechanism Description | Twelve mutational changes at 10 positions were identified, with 473Ala-Thr representing a new mutation site. New amino acid substitutions, 465Gln-Arg, 466Leu-Ser, 468Gln-Lys, and 477Ala-Thr in cluster I and 527Ile-Met and 529Ser-Leu in cluster II, were described, thereby emphasizing the high variability of these amino acid positions. Codon 481 was mutated on 32 separate occasions, which indicates a central role of this amino acid. All in vivo isolates that demonstrated two or three amino acid changes exhibited high-level resistance. Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

| Mechanism Description | Twelve mutational changes at 10 positions were identified, with 473Ala-Thr representing a new mutation site. New amino acid substitutions, 465Gln-Arg, 466Leu-Ser, 468Gln-Lys, and 477Ala-Thr in cluster I and 527Ile-Met and 529Ser-Leu in cluster II, were described, thereby emphasizing the high variability of these amino acid positions. Codon 481 was mutated on 32 separate occasions, which indicates a central role of this amino acid. All in vivo isolates that demonstrated two or three amino acid changes exhibited high-level resistance. Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

| Mechanism Description | Twelve mutational changes at 10 positions were identified, with 473Ala-Thr representing a new mutation site. New amino acid substitutions, 465Gln-Arg, 466Leu-Ser, 468Gln-Lys, and 477Ala-Thr in cluster I and 527Ile-Met and 529Ser-Leu in cluster II, were described, thereby emphasizing the high variability of these amino acid positions. Codon 481 was mutated on 32 separate occasions, which indicates a central role of this amino acid. All in vivo isolates that demonstrated two or three amino acid changes exhibited high-level resistance. Interestingly enough, all of these isolates showed the mutational change 481His-Asn, which is capable of conferring low-level resistance on its own, thereby indicating a two-step resistance mechanism in vivo to high-level resistance within these isolates. High-level resistance in vivo, however, was not demonstrated to occur through multiple mutations alone. The single amino acid substitution 468Gln-Lys also causes high-level resistance. | |||

|
||||
| Key Molecule: Virginiamycin B lyase (VGBB) | [12] | |||
| Resistant Disease | Staphylococcus aureus infection [ICD-11: 1B54.0] | |||
| Molecule Alteration | Expression | Inherence |
||
| Resistant Drug | Quinupristin/Dalfopristin | |||
| Experimental Note | Identified from the Human Clinical Data | |||

| Experiment for Molecule Alteration |
PCR amplification and sequence alignments assay | |||
| Experiment for Drug Resistance |
Spectrophotometric and fluorometric assay | |||
| Mechanism Description | Virginiamycin B lyase (Vgb) inactivates the quinupristin component of Synercid by lactone ring opening and the enzyme promotes this reaction by intramolecular Beta-elimination without the involvement of a water molecule. Replacement of the conserved active site residues His228, Glu268, or His270 with alanine reduces or abolishes S. cohnii Vgb activity. Residue Lys285 in S. cohnii Vgb is spatially equivalent to the S. aureus Vgb active site residue Glu284. | |||
