Abstract The aim of this study was to evaluate the phenotypic and molecular patterns biofilm formation in infection colonization isolates Acinetobacter spp. from patients who were admitted a public hospital Recife-PE-Brazil 2018-2019. For analysis, evaluated by crystal violet staining method; search virulence genes (bap, ompA, epsA, csuE bfmS) performed PCR; ERIC-PCR for typing. Amongst 38 isol...

Staphylococcus aureus can cause foodborne poisoning and form biofilms, reducing enterotoxin production the penetration rate of antibiotics. Therefore, infections poisonings caused by S. be difficult to treat. The aim this study was investigate antibiotic resistance levels isolates obtained from raw milk presence biofilm mecA gene reveal risk public health. isolated in 30 (30%) 100 samples Van p...

The capacity of Staphylococcus aureus to form biofilms on host tissues and implanted medical devices is one of the major virulence traits underlying persistent and chronic infections. The matrix in which S. aureus cells are encased in a biofilm often consists of the polysaccharide intercellular adhesin (PIA) or poly-N-acetyl glucosamine (PNAG). However, surface proteins capable of promoting bio...

Cigarette smoking is a major risk factor in lung carcinogenesis via carcinogens such as polycyclic aromatic hydrocarbons (PAHs) and nitrosamines. In this study, we used benzo[a]pyrene (BaP) as the classic PAH compound and BEAS-2B cells, a model of normal human bronchial epithelial cells, to investigate whether 5,7-dimethoxyflavone (5,7-DMF) and 3',4'-DMF compared with resveratrol (RV) have chem...

Neural tube defects (NTDs) are among the most common and severe congenital malformations and result from incomplete closure of the neural tube during early development. Maternal exposure to polycyclic aromatic hydrocarbons (PAHs) has been suggested to be a risk factor for NTDs and previous studies imply that the mechanism underlying the association between PAH exposure and NTDs may involve oxid...

Metabolism of benzo(a)pyrene (BaP) in vivo and in vitro was studied using two benthic fish species, English sole (Parophrys vetulus) and starry flounder (Platichthys stellatus), and Sprague-Dawley rats. At 24 h after administration of BaP (7.9 mumol/kg of body weight) to fish either p.o. (Experiment 1) or i.p. (Experiment 2), the specific activity of binding of BaP metabolites to hepatic DNA (p...

BACKGROUND Parents of children with autism have higher rates of broad autism phenotype (BAP) features than parents of typically developing children (TDC) in Western countries. This study was designed to examine the rate of BAP features in parents of children with autism and the relationship between parental BAP and the social impairment of their children in a Chinese sample. METHODS A total o...

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon ubiquitously existing in the environment. Its metabolites have been shown to cause DNA damage and cellular dysfunction in humans. Panax ginseng C.A. Meyer is a Chinese medicinal herb, and ginsenosides are the main active constituent of ginseng. Accumulating evidence had indicated that ginseng extract and ginsenosides possess cytoprotecti...

The objective of this study was to characterize the clonal profile, virulence factors and antimicrobial resistance, particularly oxacillin resistance, of Staphylococcus aureus isolated from sheep milk. Milk samples were collected from all teats for the California Mastitis Test (CMT), somatic cell count, identification of S. aureus, investigation in these strains of genes encoding toxins (sea, s...

Enterococcus faecalis biofilm traits and distribution characteristics in China have not been clarified. This study aimed to determine the prevalence and characteristics of E. faecalis biofilm formation in a sample of clinical isolates and to explore the virulence factors associated with biofilm formation in those isolates. A total of 265 E. faecalis isolates were collected from patients in Shen...
