Spatio-selection in Expanding Bacterial Colonies
- Physica A
, 1999
"... Segregation of populations is a key question in evolution theory. One important aspect is the relation between spatial organization and the population 's composition. Here we study a specific example -- sectors in expanding bacterial colonies. Such sectors are spatially segregated sub-populatio ..."

Ultrastructure of surface film of bacterial colonies
- J
, 1993
"... The structure of the surface of colonies of various Gram-negative and Gram-positive bacteria was examined by transmission electron microscopy. The results indicate that bacterial colonies in the course of their development produce a film which becomes thicker with increased duration of growth. The b ..."

COMPUTATIONAL APPROACH TO COUNT BACTERIAL COLONIES
"... Research involving bacterial pathogens often requires enumeration of bacteria colonies. Bacterial colony enumeration is an essential tool for many widely used biomedical assays. Bacterial colony enumerating is a low throughput, time consuming and labor intensive process. Since there might exist ..."

The Artistry of Bacterial Colonies and the Antibiotic Crisis
- in Coherent Structures in Complex Systems. Selected Papers of the XVII Sitges Conference on Statistical Mechanics. Edited by
, 2001
"... this paper we present the response of the colonial growth dynamics to the presence of antibiotics in various stressful conditions (For further details see [24]). In medicine, resistance to antibiotics is usually considered a qualitative property: either a specific strain of bacteria is resistant to ..."

to a specific antibiotic or it is not. The bacteria are generally regarded as being `resistant' if they can tolerate the maximal concentration of the antibiotic which is non-toxic to the treated humans or animals. However, it is known that bacterial colonies are often more resistant than
AN AUTOMATED APPROACH FOR BACTERIAL COLONY COUNTER
"... Counting of bacterial colonies is complex task for microbiologist. To a large extent, accurate colony counting depends on the ability to see colonies distinctly, whether viewed by the naked eye or by an automated instrument. An increased area of focus in Microbiology is the automation of counting me ..."

A Novel Methodology for Automatic Bacterial Colony Counter
"... Many biological procedures depend on an accurate count of the bacterial colonies and other organisms. In biomedical research and clinical diagnosis, there is a great need to quantify the amount of bacteria in the samples.This paper presents a simple and cost effective methodology for automatically c ..."

Studies of Sector Formation in Expanding Bacterial Colonies
- Europhys. Lett
, 1999
"... . -- We study sector formation in expanding bacterial colonies grown on a substrate with low level of nutrient. Bursts of sectors are observed both during compact growth on soft agar and during branching growth on semi-solid agar. For theoretical studies of these bursts we employ two mathematical mo ..."

Simulation Study of Bacterial Colony with Multiplying Rods
, 2003
"... Abstract. A microscopic model for a bacterial individual is proposed, and applied investigation of the bacterial colony. B. Subtilis is considered as a sample, which is regarded as a rod molecule moving and rotating on the substrate including the diffusive nutrients. The model is analyzed by Monte C ..."
