Epidemiology of community-onset Staphylococcus aureus infections in pediatric patients: an experience at a Children's Hospital in central Illinois

Table 3 Resistance patterns of MRSA isolates* stratified by healthcare-associated (HA) risk factors.

	No. (%)
	Patients with HA risk factors	Patients without HA risk factors	P
Non-MDR MRSA isolates	n = 29	n = 70	0.20
Invasive infections	9 (9)	12 (12)
SSTIs	20 (20)	58 (59)
MDR MRSA isolates	n = 4	n = 5	0.21
Invasive infections	3 (33)	1 (11)
SSTIs	1 (11)	4 (45)

* MDR phenotype was not determined in 2 MRSA isolates that were susceptible to clindamycin but resistant to erythromycin and tetracycline because of lack of D test results. These 2 MRSA isolates caused skin infections in patients without healthcare-associated risk factors.
