SCCmec types of MRSA isolates from community and hospital-related colonized subjects and from hospitalized patients
| SCCmec type | No. of isolates
|
||
|---|---|---|---|
| Community colonizers (n = 64) | Hospital-related colonizers (n = 27) | Clinical hospital strains (n = 17) | |
| I | 1 | 1 | 0 |
| II | 0 | 1 | 0 |
| III | 1 | 9 | 10 |
| IIIA | 0 | 2 | 4 |
| IV | 56 | 11 | 1 |
| Type III varianta | 4 | 3 | 2 |
| Not typedb | 1 | 0 | 0 |
| New variantc | 1 | 0 | 0 |
a
The new type III variant was defined when specific mecA type III loci E and F were present (31).
b
One isolate that was not typed was positive only for the mecA gene, with no PCR product obtained with the SCCmec gene tested.
c
An isolate contained the specific A, D, E, and F loci, which were type I or type III specific and was designated the new type variant.
