Staphylococcus simulans was identified as the etiological agent of osteomyelitis and septic arthritis in an adult male who had sustained a fracture of the fibula and syndesmosis separation which required the installation of orthopedic hardware. Identifying characteristics and antibiograms for this organism, recovered from blood, wound exudate, and deep tissue samples, were determined. Recent ev...

Coagulase-negative Staphylococci (CoNS) form a part of the skin flora and commonly cause nosocomial bloodstream and catheterrelated infections. According to their relatively low virulence, it is important to detect the virulence factors of clinical isolates. The production of extracellular polymers and formation of biofilms belong to virulence factors. We studied clinical isolates of CoNS and c...

Cellular slime molds are enigmatic and fascinating organisms whose life cycles of both single and multicellular stages have long charmed and perplexed biologists (1). Increasingly, cellular slime molds—of which the most widely studied is Dictyostelium discoideum—have been used as models to study the maintenance of cooperation, but viewed from this perspective, there are puzzles to resolve. Two ...

This article presents a novel bio-inspired navigation principle for swarm robotics that is based on a technique of signal propagation that was inspired by slime mold. We evaluated this strategy in a variety of simulation experiments that simulates a collective cleaning scenario. This scenario includes several sub-tasks like exploration, information propagation and path finding. Using the slime ...

1. Antibodies to slime molds were produced by injecting D. discoideum and D. purpureum amebas from 48 hour cultures into rabbits. 2. Anti-D. discoideum and anti-D. purpureum sera caused agglutination of homologous amebas from 24 to 26 hour cultures, agglutination of certain heterologous amebas from 30 to 36 hour cultures, and agglutination of all heterologous amebas from 43 to 48 hour cultures....

Biofouling, also known as barnacles and slime, may not be the trendiest, high-tech topic of conversation in the world of operational energy. Most would rather discuss a new weapon system or innovative green technology that allows Sailors and Marines to increase operational tempo or achieve more efficient fuel consumption. What most people don’t realize is that biofouling may actually represent ...

Microplasmodia of the slime mold Physarum polycephalum form a small link degree transportation network in a percolation transition in order to forage. We model this transition analytically within the configuration model of graph theory utilizing all partaking types of nodes. Quite generally, we find that at the percolation transition the formation of a small link degree network is topologically...

The use of a film-flow reactor for studying the kinetics of substrate removal is described. The reactor provides a means of maintaining a uniform layer of biologically active slime which is stationary while the feed solution is made to flow over the slime surface in a thin film. The study was designed to evaluate process limitations in the trickling filter process which is designed for the biol...
