Phenotypic and genotypic characterization of biofilm formation in Staphylococcus haemolyticus

Current Microbiology

Abstract

Staphylococcus haemolyticus is one of the most frequently isolated coagulase-negative staphylococci. The ability to produce biofilm has contributed to its emergence as a nosocomial pathogen. In this study, some growth conditions were tested to determine their influence on biofilm formation. Brain-heart infusion (BHI) broth containing glucose was used to screen 64 clinical strains. A strong biofilm producer strain showed cells surrounded by a thick layer of extracellular matrix. The presence of atlE, fbp, bap, and icaA genes was analyzed. We concluded that S. haemolyticus biofilm production can be increased with cells grown in BHI, and highlighted that it could be an ica-independent process.

Biofilm & Infectious Disease

Biofilm formation is a key virulence factor for a wide range of microorganisms that cause chronic infections.Here is the latest research on biofilm and infectious diseases.

Biofilms

Biofilms are adherent bacterial communities embedded in a polymer matrix and can cause persistent human infections that are highly resistant to antibiotics. Discover the latest research on Biofilms here.
