Tīmeklis2024. gada 26. okt. · Panton-Valentine leukocidin (PVL) is a Staphylococcus aureus virulence factor codified by lukSF-PV genes. Single-nucleotide polymorphisms (SNPs) at lukSF-PV genes can lead to two PVL sequence variants (R and H) generating different PVL isoforms. This study analyzed lukSF-PV genes SNPs among four … Parvalbumin (PV) is a calcium-binding protein with low molecular weight (typically 9-11 kDa). In humans, it is encoded by the PVALB gene. It is not a member of the albumin family; it is named for its size (parv-, from Latin parvus small) and its ability to coagulate. It has three EF hand motifs and is structurally related to calmodulin and troponin C. …

TīmeklisPanton–Valentine leukocidin (PVL) is a cytotoxin—one of the β-pore-forming toxins.The presence of PVL is associated with increased virulence of certain strains (isolates) of Staphylococcus aureus.It is present in the majority of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) isolates studied and is the cause of … TīmeklisA total of 15 (15.3%) of the S. aureus isolates were Luk-PV positive. The majority (13 of 15) of Luk-PV positive S. aureus were methicillin susceptible (MSSA). Three of the S. aureus isolates were positive for both MecA and Luk-PV genes – two of these produced PBP2a. Of five isolates of S. aureus recovered from wound, only one possessed the ... Tīmeklis2024. gada 31. janv. · Abstract.
