Brazilian Journal of Microbiology Volume 48, Issue 1, January–March 2017, Biofilm production and beta-lactamic resistance in Brazilian Staphylococcus aureus isolates from bovine mastitis. Abstract Staphylococcus spp. play an important role in the etiology of bovine mastitis.
Staphylococcus aureus is considered the most relevant species due to the production of virulence factors such as slime, which is required for biofilm formation. This study aimed to evaluate biofilm production and its possible relation to beta-lactamic resistance in 20 S. aureus isolates from bovine mastitic milk. The isolates were characterized by pheno-genotypic and MALDI TOF-MS assays and tested for genes such as icaA, icaD, bap, agr RNAIII, agr I, agr II, agr III, and agr IV, which are related to slime production and its regulation. Biofilm production in microplates was evaluated considering the intervals determined along the bacterial growth curve.

Abstract There is increasing concern about the public health impact of methicillin-resistant Staphylococcus aureus.
Food and animal are vectors of transmission, but the contribution of a contaminated environment is not well characterized. With regard to this, staphylococcal biofilms serve as a virulence factor, allowing MRSA strains to adhere to surfaces and other materials used in the food industry.

Highlights S. enterica and S. aureus formed mono- and dual-species biofilms on stainless steel.
Both bacterial species formed less biofilm (ca. 10-fold) under co-culture. Resistance of each species was not influenced by interspecies interactions. Bacterial interactions influenced both dominance and resistance of each strain. Front Microbiol. 2016; 7: 390.

Anti-biofilm formation of a novel stainless steel against Staphylococcus aureus. Open Access Abstract Staphylococcus aureus (S. aureus) is a bacterium frequently found proliferating on metal surfaces such as stainless steels used in healthcare and food processing facilities.
Past research has shown that a novel Cu-bearing 304 type stainless steel (304CuSS) exhibits excellent antibacterial ability (i.e. against S. aureus) in a short time period (24 h.). This work was dedicated to investigate the 304CuSS's inhibition ability towards the S. aureus biofilm formation for an extended period of 7 days after incubation. It was found that the antibacterial rate of the 304CuSS against sessile bacterial cells reached over 99.9% in comparison with the 304SS. Keywords. J Food Sci. 2015 Oct;80(10):M2279-86.

AFRICAN JOURNAL OF MICROBIOLOGY RESEARCH Vol.8(36), pp. 3347-3353 , September 2014 Action of sanitizers on Staphylococcus aureus biofilm on stainless steel and polypropylene surfaces. The interest of researchers in various areas has resulted in the investigation of different biofilm systems using a wide range of techniques.
Biofilms are microbial communities consisting of mono or multi-species sessile cells, embedded in a matrix of extracellular polymers (exopolysaccharides-EPS) adhering to surfaces. In the food industry, the existence of biofilms is quite problematic, being responsible for the economic loss and contamination of food. Consequently, research involving the characterization of the ability of microbial biofilm formation is relevant for the subsequent studies using sanitizing and antibiotic agents for prevention or remediation of surfaces with already formed biofilms.

Biofilm production and antibiotic susceptibility profiles of Staphylococcus aureus isolated from HIV and AIDS patients in the Limpopo Province, South Africa Abstract Staphylococcus aureus is a common pathogen associated with nosocomial as well as community acquired infections.
Despite multiple reports on the severity and recurrent nature of S. aureus infection, the pathogenesis as well as antibiotic susceptibility profiles of S. aureus infecting HIV and AIDS patients has not been well studied in Limpopo Province, South Africa. Hence, the study was aimed at determining the biofilm producing capability and antibiotic resistance profiles of the S. aureus isolated from drinking water and clinical samples from HIV patients in the Limpopo Province.

PLOS - NOV 2009 - Molecular Characterization of a Novel Staphylococcus Aureus Surface Protein (SasC) Involved in Cell Aggregatio. Background Staphylococci belong to the most important pathogens causing implant-associated infections.
Colonization of the implanted medical devices by the formation of a three-dimensional structure made of bacteria and host material called biofilm is considered the most critical factor in these infections. To form a biofilm, bacteria first attach to the surface of the medical device, and then proliferate and accumulate into multilayered cell clusters. Biofilm accumulation may be mediated by polysaccharide and protein factors. Methology/Principal Findings The information on Staphylococcus aureus protein factors involved in biofilm accumulation is limited, therefore, we searched the S. aureus Col genome for LPXTG-motif containing potential surface proteins and chose the so far uncharacterized S. aureus surface protein C (SasC) for further investigation.

Food Control Volume 25, Issue 2, June 2012, Influence of temperature and surface kind on biofilm formation by Staphylococcus aur. Open Access Abstract This study aimed to assess the adhesion, detachment kinetic and biofilm formation of Staphylococcus aureus isolates from food services surfaces on stainless steel and polypropylene surfaces when cultivated in a vegetable-based broth at 7 and 28 °C, and the efficacy of peracetic acid (30 mg/L) and sodium hypochlorite (250 mg/L) in removing the bacterial cells from the matrix of the preformed biofilm.
The isolates adhered over 4 Log cfu/cm2 regardless the surface kind and incubation temperature. Cell detachment was around 3 Log cfu/cm2 over the first six contacts with agar characterizing a high persistence of cells on the tested surfaces. Number of cells (5–7 Log cfu/cm2) needed for biofilm formation was noted at all experimental systems already after 3 days of incubation.
