Bioirrigation or the transport of fluids into the sediment matrix due to the activities of organisms such as bloodworms (larvae of Diptera, Chironomidae), has substantial impacts on sediment respiration in lakes. However, previous quantifications of bioirrigation impacts of Chironomidae have been limited by technical challenges such as the difficulty to separate faunal and bacterial respiration...

In this work, corrections are made to the descriptions of the species Anoxybacillus pushchinoensis corrig. and the genus ANOXYBACILLUS: Experiments to determine the relationship of A. pushchinoensis K1(T) to oxygen showed that it was capable of aerobic growth, but preferred to grow anaerobically. During aerobic growth, the redox indicator resazurin was reduced as a result of hydrogen gas produc...

We reported in this work the preparation of novel 1,4-disubstituted-1,2,3-triazoles derivatives from Dglucose and D-fructose and their in vitro antibacterial activity against Mycobacterium tuberculosis were evaluated. The chemical synthesis was performed based on the 1,3-dipolar cycloaddition reaction, and antimicrobial activity was determined based on Resazurin Microtiter Assay against Mycobac...

The conventional method for quantification of Chlamydia infection using fluorescence microscopy typically involves time- and labor-intensive manual enumeration, which is not applicable for a large-scale analysis required for an inhibitory compound screen. In this study, an alamarBlue (resazurin) assay was adopted to measure Chlamydia infection by measuring the redox capability of infected host ...

In Mexico, the decoction of rhizome Krameria pauciflora is taken against diarrhea and dysentery. Our objective was to determine antibacterial activity on growth causal bacteria gastrointestinal infections. 
 The plant dried pulverized at room temperature, this included leaves, rhizome, complete (stem–leaves–rhizome). These were macerated consecutively 48 h in hexane, dichloromethane, metha...

Natural products, such as the ethanolic propolis extract (PE), have been shown to be a safe and effective therapeutic alternative for treatment of fungal skin nail diseases. However, presence resin physicochemical characteristics sometimes difficult reading determination breakpoints in vitro tests, evidencing need alternatives that facilitate reading. The present study aimed standardize use res...

Bacterial vaginosis is a common vaginal infection associated with numerous gynecological and obstetric complications. This condition is characterized by the presence of thick adherent vaginal biofilms, composed mainly of Gardnerella vaginalis. This organism is thought to be the primary aetiological cause of the infection paving the way for various opportunists to colonize the niche. Previously,...
