- Abstract:
- ... The objective of our study was to evaluate prevalence of selected bacterial and fungal pathogens of mastitis in dairy cattle in north-eastern Poland. Our study was conducted from 2013 to 2019 in 1,665 clinically and sub-clinically infected quarter milk samples (2013, n = 368; 2014, n = 350; 2015, n = 290; 2016, n = 170; 2017, n = 173; 2018, n = 224; and 2019, n = 90). The isolation and identificat ...

This paper reports a colorimetric-fluorescent dual-signal lateral flow assay (LFA) based on vancomycin (Van)-modified SiO₂–Au-QD tags for sensitive and quantitative detection of Staphylococcus aureus (S. aureus). The combination of high-performance Van-tags and detection antibodies integrated into the LFA system produced assays with high sensitivity and specificity. The visualization limit of the ...

- Abstract:
- ... Early-diagnosis and treatments of skin and soft tissue infections remain a huge challenge due to the difficulties in the detection of trace amounts of bacteria. We develop here a novel method through CRISPR-Cas12a based recycling signal amplification cascades and demonstrated its feasibility of Staphylococcus aureus detection in a sensitive and accurate way. The highlights of the proposed method a ...

Objective: Methicillin-resistant Staphylococcus aureus (MRSA) ST8-t008 of the pulsotype USA300 and the Latin American variant (USA300-LV) are the predominant virulent MRSA clonal lineages on the American continent. In Europe, the occurrence of USA300 or USA300-LV has often been related to international travel or outbreaks in hospitals. The replacement of local epidemic MRSA clones by these hypervi ...

Type I interferon (IFN) induction is a critical component of innate immune response to viral and bacterial infection, including S. aureus, but whether it activates the signaling in macrophages and the regulation mechanisms is less well understood. Here we show that S. aureus infection promoted the IFN-β mRNA expression and stimulator of IFN genes (STING)/TANK-binding kinase 1 (TBK1)/interferon reg ...
