Abstract:

Abstract Background Bone marrow biopsies are often performed on patients with unclear diagnoses and cultures may be ordered for both routine bacterial, mycobacterial and fungal pathogens. They are performed in semi-sterile conditions and involve needle penetration through the skin, posing an increased risk of skin contamination. These cultures also require a substantial amount of laboratory personnel time. Methods Cultures collected from 2001-2020 were surveyed in the lab electronic record. We assessed the culture type (fungal, bacterial, mycobacterial), and the presence of pathogens and conta

Abstract:

The growth of an organism can be modeled using a growth curve. However, bacteria's growth pattern differs from other organisms. Bacterial growth is divided into four phases: lag, logarithmic, stationary, and death. The experts re-parameterized the growth curve to match the growth phase of the bacteria. Bacterial growth patterns generally do not show a single sigmoid pattern but form two curves. Therefore, the double sigmoid model is more suitable. This study modeled the growth of the Pseudomonas putida bacteria by observing the optical density of the medium. Model parameters are estimated usin

Abstract:

This bacterial infection has a major impact on public health. There are many bacteria that are able to adapt to survive in water, soil, food, and various other places. The development of bacterial infection to cause disease is influenced by several factors including the infectivity of the organism, the pathogenicity of infectious organisms, the ability of pathogenic bacteria to avoid the body's immunity, virulence factors of pathogenic bacteria, and the role of human immunity cells themselves. In the treatment of patients with bacterial infections there are some real challenges in the use of d

Abstract:

A peculiar feature of all living beings is their capability to communicate. With the discovery of the quorum sensing phenomenon in bioluminescent bacteria in the late 1960s, it became clear that intraspecies and interspecies communications and social behaviors also occur in simple microorganisms such as bacteria. However, at that time, it was difficult to imagine how such small organisms—invisible to the naked eye—could influence the behavior and wellbeing of the larger, more complex and visible organisms they colonize. Now that we know this information, the challenge is to identify the myriad

Abstract:

Abstract Biocorrosion of metal pipelines in the oil and hydrocarbon industry is frequently linked to the presence of Sulfate Reducing Bacteria (SRB) and Acid Producing Bacteria (APB). Suggested mechanisms of SRB induced corrosion are an accumulation of corrosive metabolites like hydrogen sulfide or cathodic depolarization. The APB produce organic acids as results of its metabolism. A biocide can be defined as a chemical agent that is capable of destroying living organisms. Microbiological studies have been conducted in the field to assess the efficiency of a biocide with a base of phosphonate

Abstract:

Abstract Continuous biodegradation of air pollutants i.e., volatile organic compounds (VOC), which are released to the atmosphere during many industrial operations, is one of the fastest-growing areas of bio-technology. Substantive bacterial growth, immobilization and VOC-degradation reaction, accompanied by typical fluctuations of other variables like pH, can significantly alter the general corrosion rate as well as potential for localized corrosion. Results from on-line corrosion measurements performed utilizing multiple electrochemical techniques in a large-scale, continuous bio-degradation

Abstract:

Campylobacter spp. are the most common bacterial cause of foodborne illness in the UK, with chicken considered to be the most important vehicle for this organism. The FSA agreed with industry to reduce campylobacter spp. contamination in raw chicken and issued a target to reduce the prevalence of the most contaminated chickens (those with more than 1000 cfu per gram chicken neck skin) to below 10% at the end of the slaughter process, initially by 2016. To help monitor progress, a series of UK-wide surveys were undertaken to determine the levels of campylobacter spp. on whole UK-produced, fresh

Abstract:

Organisms (i.e., plants and microorganisms) contain pigments that allow them to adapt and thrive under stressful conditions, such as elevated ultraviolet radiation. The pigments elicit characteristic spectral responses when measured by active and passive sensors. This research study focused on characterizing the spectral response of three organisms and how they compared to background spectral signatures of a complex environment. Specifically, spectra were collected from a fungus, a plant, and two pigmented bacteria, one of which is an extremophile bacterium. The samples were measured using Fou

Abstract:

The contamination of surface and subterranean drinking water supplies with nitrogen-laden agricultural wastewater is a problem of increasing concern in the U.S. and Israel. Through this research, we found that bacteria could utilize common organic wastes (e.g. paper, straw, cotton) as carbon sources under anaerobic conditions, and reduce nitrate concentrations in wastewater to safe levels. Two species of bacteria, Cellulomonas uda and a Comamonas sp., were required for dentitrification. Celulomonas uda degraded cellulose and reduced nitrate to nitrite. In addition, it excreted soluble organic

Abstract:

Campylobacter spp. are the most common bacterial cause of foodborne illness in the UK, with chicken considered to be the most important vehicle of transmission for this organism. It is estimated there are 500,000 cases of campylobacteriosis in the UK annually, with Campylobacter jejuni (C. jejuni) and Campylobacter coli (C. coli) accounting for approximately 91% and 8 % of infections, respectively. Although severe infection in humans is uncommon, treatment is seldom needed for human infection but usually involves the administration of a macrolide (e.g., azithromycin) or a fluoroquinolone (e.g.

Abstract:

Ammonia waste removal in recirculating aquaculture systems is typically accomplished via the action of nitrifying bacteria in specially designed biofilters that oxidize ammonia to produce nitrate. In the majority of these systems nitrate is discharged to the environment through frequent water exchanges. As environmental considerations have made it necessary to eliminate nitrate release, new strategies for nitrate consumption are being developed. In the funding period we showed that ammonia removal from wastewater could take place by an anaerobic ammonia oxidation process carried out by bacteri

Abstract:

Animal-associated microbiomes are critical to the well-being and proper functioning of the animal host, but only limited studies have examined in-sect microbiomes across different developmental stages. These studies revealed large shifts in microbiome communities, often because of significant shifts in diet during insects’ life cycle. Establishing insect colonies as model laboratory organisms and understanding how to properly feed and care for animals with complex and dynamic life cycles requires improved data. This study examined laboratory raised green June beetles (Cotinis nitida) captured
