Short communication: Association between the accessory gene regulator (agr) group and the severity of bovine mastitis caused by Staphylococcus aureus
(Elsevier B.V., 2021-03-01)
Staphylococcus aureus can elicit mild to more severe degrees of mastitis in cattle, depending on the response of the host's immune system and the virulence factors of the specific isolate. Several virulence factors are ...
Expression of superantigens and the agr system in Staphylococcus epidermidis
(2018-02-01)
Infections with coagulase-negative staphylococci (CoNS) can involve the production of toxins such as superantigens, which contribute to tissue degradation and inflammatory immune responses. The accessory gene regulator ...
Identification of the agr Peptide of Listeria monocytogenes
(Frontiers in Microbiology, 2016)
Listeria monocytogenes (Lm) is an important food-borne human pathogen that is able
to strive under a wide range of environmental conditions. Its accessory gene regulator
(agr) system was shown to impact on biofilm formation ...
Detection of the agr System and Resistance to Antimicrobials in Biofilm-Producing S. epidermidis
(2020-12-03)
The ability of Staphylococcus epidermidis to produce virulence factors, such as biofilm, added to its increased resistance to antimicrobials can cause infections that are difficult to treat. Many staphylococcal virulence ...
Salicylic acid stabilizes Staphylococcus aureus biofilm by impairing the agr quorum-sensing system
(Nature Publishing Group, 2021-02)
Salicylic acid (SAL) has recently been shown to induce biofilm formation in Staphylococcus aureus and to affect the expression of virulence factors. This study was aimed to investigate the effect of SAL on the regulatory ...

Influence of drainage and nutrient-solution nitrogen and potassium concentrations on the agronomic behavior of bell-pepper plants cultivated in a substrate
(Public Library Science, 2017-07-05)
The interactive effects of N (6, 9, 12 and 15 mmol L-1) and K (3, 5, 7, and 9 mmol L-1) concentrations in nutrient solutions were evaluated on bell pepper grown in a coconut-coir substrate and fertilized without drainage. ...
