Molecular docking, quorum quenching effect, antibiofilm activity and safety profile of silver-complexed sulfonamide on .

Microbial infections caused by sessile microorganisms are known to be a more challenging issue than infections caused by the same microorganisms in the planktonic state. is an opportunistic pathogen and biofilm-forming agent. This species presents intense cellular communication mediated by signaling molecules.

Antimicrobial activity and phytochemical characterization of Carya illinoensis.

Carya illinoensis is a widespread species, belonging to the Juglandaceae family, commonly known as Pecan. Popularly, the leaves have been used in the treatment of smoking as a hypoglycemic, cleansing, astringent, keratolytic, antioxidant, and antimicrobial agent. The following research aimed to identify for the first time the phytochemical compounds present in the leaves of C.

Antimicrobial, antitrypanosomal and antibiofilm activity of Equisetum hyemale.

This study evaluates, for the first time, the antibiofilm, antimicrobial and antiparasitic potential of crude extract and fractions of stems of Equisetum hyemale against several infectious agents (bacteria, fungi, Mycobacterium and Trypanosomes) by broth microdilution technique and investigates the phenolic composition of the plant by high performance liquid chromatography. The crude extract and fractions showed antimicrobial activity, as they were capable of inhibiting the growth of bacteria in minimal inhibitory concentrations (MICs) ranging from 52.4 mg/mL to 3.

Chlorhexidine activity against bacterial biofilms.

Background: A biofilm is a complex microbiological ecosystem deposited on surfaces. Microorganisms in form of biofilms are of particular clinical concern because of the poor response to antimicrobial treatments. This study aimed to determine whether bacterial and fungal biofilms are able to resist the antimicrobial activity of chlorhexidine, a powerful antiseptic widely used in the hospital environment.

Antimicrobial activity of Amazon Astrocaryum aculeatum extracts and its association to oxidative metabolism.

Several compounds present in fruits as polyphenols are able to kill or inhibit the growth of microorganisms. These proprieties are relevant mainly in tropical areas, as Amazonian region where infectious are highly prevalent. Therefore, this study investigated the antimicrobial activity of tucumã Amazonian fruit against 37 microorganisms.

Antimicrobial activity of Amazonian oils against Paenibacillus species.

The Gram-positive, spore-forming bacterium Paenibacillus larvae is the primary bacterial pathogen of honeybee brood and the causative agent of American foulbrood disease (AFB). One of the feasible alternative treatments being used for their control of this disease is essential oils. In this study in vitro antimicrobial activity of Andiroba and Copaíba essential oils against Paenibacillus species, including P.
