Temporal Bacteriostatic Effect and Growth Factor Loss in Equine Platelet Components and Plasma Cultured with Methicillin-Sensitive and Methicillin-Resistant Staphylococcus aureus: A Comparative In Vitro Study

Table 2

PF-4 (pg/mL) concentration in every blood component cultured with either MSSA or MRSA at 6 hours.

Blood components	MSSA	MRSA
Platelet-rich plasma (PRP)	2331 (3561)	2012 (2310)^a
Platelet-rich gel (PRG)	2703 (2549)	2991 (4992)^c
Leukocyte-poor plasma (LPP)	2066 (3187)	3553 (3187)^c
Leukocyte-poor gel (LPG)	1216 (2772)^a	844 (5704)^a
Plasma	685 (2558)^a	594.5 (2172.5)
Heat-inactivated plasma (IP)	4087 (8054)^b	2756 (3957)^c
PRP + NID	1322.5 (1842.75)	1322.5 (1842.75)
LPP + NID	1322 (2103)	1322 (2103)

Lowercase letters represent significant differences in the same column. ^aSignificantly different from IP ( > 0.05). ^bSignificantly different from PRP + NID and LPP + NID ( > 0.01). ^cSignificantly different from plasma ( > 0.01). NID: nonionic detergent.
