Background: Nowadays, new methods such as scrub with an efficient agent for short time are used for the prevention of communicable diseases and infection control at the most of operating rooms. But, at most of our operating rooms, surgical teams use traditional and routine hand scrub (with Betadine more than 3 min). The aim of this clinical trial was to compare efficacy of Betadine and an alcoh...

The present study proposed the isolation of arsenic resistant bacteria from wastewater. Only three bacterial isolates (MNZ1, MNZ4 and MNZ6) were able to grow in high concentrations of arsenic. The minimum inhibitory concentrations of arsenic against MNZ1, MNZ4 and MNZ6 were 300 mg/L, 300 mg/L and 370 mg/L respectively. The isolated strains showed maximum growth at 37 °C and at 7.0 pH in control...

Microbiological experiments show that the colonies of the bacterium bacillus subtilis placed on a dish filled with an agar medium and nutrient form varied spatial patterns while the individual cells grow, reproduce and migrate on the dish in clumps. In this paper, we discuss a system of reaction-diffusion equations that can be used with a view to modelling this phenomenon and we solve it numeri...

Bacterial colony enumeration is an essential tool for many widely used biomedical assays. This chapter introduces a cost-effective and fully automatic bacterial colony counter which accepts digital images as its input. The proposed counter can handle variously shaped dishes/plates, recognize chromatic and achromatic images, and process both color and clear medium. In particular, the counter can...

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 hundreds or thousands of colonies on a Petri dish, and the counting process is often manually perform...

BACKGROUND Use of protective footwear before entering the intensive care units is enforced with the assumption that it lowers the incidence of bacterial floor colonization. The present study was carried out to find the efficacy of protective footwear on bacterial floor colonization. METHODS The study was carried out in the intensive care unit of a tertiary care hospital. The study was divided...

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 methods.. Further in an Industry thousands of such samples are formed per day and colonies on each ...

In microbiology it is diagnostically useful to recognize various genera and species of bacteria. It can be achieved using computer-aided methods, which make the recognition processes more automatic and thus significantly reduce the time necessary for the classification. Moreover, in case of diagnostic uncertainty (the misleading similarity in shape or structure of bacterial cells), such methods...

Collective surface migration of bacterial cells on a growth medium can lead to interesting spatiotemporal patterns and dynamical behaviors. Studying the rich behavior of these swarming colonies can provide insight in how the multicellular organisms were originally formed. Bacterial swarming is an example of emergent behavior as a result of interplay between the collective interactions of a popu...
