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 3

PF-4 (pg/mL) concentration in every blood component cultured with either MSSA or MRSA at 24 hours.

Blood components	MSSA	MRSA
Platelet-rich plasma (PRP)	3872 (6851.50)^a	2278 (2814)^a
Platelet-rich gel (PRG)	897 (3915.5)	2491 (2124)^a
Leukocyte-poor plasma (LPP)	4671 (4621)^a	2916 (4275)^a
Leukocyte-poor gel (LPG)	1668 (2389)	2119 (3588)^a
Plasma	2809.5 (3163.5)^a	4084 (6033)^a
Heat-inactivated plasma (IP)	3022 (3086)^a	4615 (9188)
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 PRP + NID and LPP + NID ( > 0.05). Significantly different concentrations for both bacteria in IP ( > 0.05). NID: nonionic detergent.
