We assessed the in vitro activity of micafungin against preformed Candida biofilms by measuring the concentration of drug causing the most fungal damage and inhibition of regrowth. We studied 37 biofilm-producing Candida spp. strains from blood cultures. We showed that micafungin was active against planktonic and sessile forms of Candida albicans strains and moderately active against Candida pa...

Current understanding of animal phylogeny has provided new insight on the evolution of the ancestors of the Euchordata (cephalochordates1vertebrates). Modern, adult euchordates possess a capacity for swimming, displacing themselves through water independently of currents. Swimming is achieved by the presence of a fin and axial body movements. However, the classic hypothesis on the origin of euc...

Planktonic and sessile susceptibilities to micafungin were determined for 30 clinical isolates of Candida albicans obtained from blood or other sterile sites. Planktonic and sessile MIC(90)s for micafungin were 0.125 and 1.0 microg/ml, respectively.

The high tolerance of biofilm-grown Burkholderia cepacia complex bacteria against antimicrobial agents presents considerable problems for the treatment of infected cystic fibrosis patients and the implementation of infection control guidelines. In the present study, we analyzed the tolerance of planktonic and sessile Burkholderia cenocepacia J2315 cultures and examined the transcriptional respo...

Invasive ants often enter into facultative mutualisms that frequently lead to outbreaks of the hemipteran partner. Native ants may also enter into similar mutualisms but often these do not lead to outbreaks. However, field studies comparing the impact of an invasive and native ant on a honeydew-producing hemipteran are lacking. We monitored numerical changes of the black citrus aphid, Toxoptera...

Immiscible polymers are often blended together to create new materials with desired properties. Knowledge of the interfacial tension between the immiscible polymers is important when designing such blending processes. Traditional methods of measuring the interfacial tension between low molecular weight fluids, e.g., the pendant or sessile drop method, the Wilhelmy balance, and the spinning drop...

Choanoflagellates are filter feeding heterotrophic nanoflagellates. Fluid flow generated by the motion of the flagellum delivers suspended prey particles to the surface of a crown-like filtering apparatus. Hydrodynamic characteristics are consequently of great importance to understanding prey capture in these organisms. This paper reports on the use of video-microscopy to investigate the hydrod...

We investigate numerically quasi-steady internal flows in an axially symmetrical evaporating sessile droplet depending on the ratio of substrate to fluid thermal conductivities, volatility, contact angle and size. Temperature distributions vortex structures are obtained for droplets 1-hexanol, 1-butanol ethanol. To this purpose, hydrodynamics drop, effects conduction diffusion vapor air have be...

Abstract Sessile drop creation in weightlessness is critical for designing scientific instruments space applications and manipulating organic or biological liquids, such as whole human blood DNA drops. It requires perfect control of injection, spreading, wetting; however, the simple act creating a on substrate more complex than it appears. A new macroscopic model derived to better understand th...
