Wild waterfowl, particularly dabbling ducks such as mallards (Anas platyrhynchos), are considered the main reservoir of low-pathogenic avian influenza viruses (LPAIVs). They carry viruses that may evolve and become highly pathogenic for poultry or zoonotic. Understanding the ecology of LPAIVs in these natural hosts is therefore essential. We assessed the clinical response, viral shedding and antibody production of juvenile mallards after intra-esophageal inoculation of two LPAIV subtypes previously ...

Campylobacter jejuni is a common cause of bacterial gastroenteritis in most parts of the world. The bacterium has a broad host range and has been isolated from many animals and environments. To investigate shedding patterns and putative effects on an avian host, we developed a colonization model in which a wild bird species, the European Robin Erithacus rubecula, was inoculated orally with C. jejuni from either a human patient or from another wild bird species, the Song Thrush Turdus philomelos. ...

Campylobacter jejuni is a recognized and common gastrointestinal pathogen in most parts of the world. Human infections are often food borne, and the bacterium is frequent among poultry and other food animals. However, much less is known about the epidemiology of C. jejuni in the environment and what mechanisms the bacterium depends on to tolerate low pH. The sensitive nature of C. jejuni stands in contrast to the fact that it is difficult to eradicate from poultry production, and even more contradictory ...

During the course of urinary tract infection (UTI) nitric oxide (NO) is generated as part of the host response. This study investigates the significance of the NO-detoxifying enzyme flavohemoglobin (Hmp) in protection of uropathogenic Escherichia coli (UPEC) against nitrosative stress. An hmp (J96Δhmp) knockout mutant of UPEC strain J96 was constructed using single-gene deletion. The viability of J96Δhmp was significantly reduced (P < 0.001) compared to the wild-type strain after exposure to the NO-donor ...

We investigated whether NO can affect the host response in human renal epithelial cells by modulating IL-6 production and mRNA expression. <b><i>Methods:</i></b> The human renal epithelial cell line A498 was infected with ...

Migratory birds have been suggested to contribute to long-distance dispersal of antimicrobial resistant bacteria, but tests of this hypothesis are lacking. In this study we determined resistance profiles and genotypes of ESBL-producing bacteria in randomly selected Escherichia coli from Franklin´s gulls (Leucophaeus pipixcan) at breeding sites in Canada and compared with similar data from the gulls' wintering grounds in Chile. Resistant E. coli phenotypes were common, most notably to ampicillin (30. ...

Urinary tract infection (UTI) is one of the most common bacterial infections in humans, and the majority are caused by uropathogenic Escherichia coli (UPEC). The rising antibiotic resistance among UPEC and the frequent failure of antibiotics to effectively treat recurrent UTI and catheter-associated UTI motivate research on alternative ways of managing UTI. Abundant evidence indicates that the toxic radical nitric oxide (NO), formed by activation of the inducible nitric oxide synthase, plays an important ...

Nitric oxide (NO) is an antibacterial factor that is produced by the enzyme inducible NO synthase (iNOS). Uroepithelial cells express iNOS in experimental models of urinary tract infection but the stimulatory and regulatory mechanisms are still unclear. We investigated the influence of uropathogenic Escherichia coli strains with different fimbrial expression and the effect of proinflammatory cytokines on the host iNOS response.A498 human kidney epithelial cells were stimulated with different uropathogenic ...

Several scenarios for ethanol production, methane production (by anaerobic digestion) and co-production of these, using autumn harvested hemp as substrate, were investigated and compared in terms of gross energy output. Steam pretreatment improved the methane production rate compared with mechanical grinding. The methane yield of steam pretreated stems was similar both with and without pre-hydrolysis with cellulolytic enzymes. Co-production of ethanol and methane from steam pretreated stems gave ...

Anaerobic high-solids single-stage stratified bed digesters have been found to be simple and flexible design candidates for small-scale reactors located in medium- to low-technology environments. In the present study, wheat straw was used as the starter material for the stratified bed. Upon green mass feeding, the anaerobically stabilised straw bed functioned both as a biofilm support and as a particulate filter. It enabled a direct onset of 7 kg VSm(-3) batch loads, added twice a week, and permitted ...

The protein concentration, protein recovery potential and the content of phenols and dietary fibre in these biomass sources and fractions were investigated.

To examine the effect of nitric oxide (NO), an endogenous component of the host defence in urinary tract infection, on the adherence of P-fimbriated uropathogenic Escherichia coli (UPEC) to human renal epithelial cells.Two wild-type UPEC strains (AD110 and IA2) and the P-fimbriated recombinant strain HB101pPIL-75 were used. Bacteria were allowed to adhere to the human renal epithelial cell line A498 and attachment was evaluated in the absence or presence of the NO donor DETA/NONOate (1 mm). Total RNA ...

The register has been a support for the coordinators in Sweden when the relatives have said one thing and the deceased person another in regards to donation. Most of the staff are positive to the register and the safety regulations around it. Most often it has been a relief for the relatives that the deceased person's wishes also have been documented in the register or in the donor card. Most decisions are still, however, made by relatives. There is still a need for more positive information about ...

Despite the apparent usefulness of prosumers in the DH grid, there has not been a systematic investigation into why Sweden has not seen a general uptake in prosumer integration in the district heating (DH) sector. The transition to 4th generation district heating (4GDH) and smart energy system concepts are conducive to prosumer integration. Nonetheless, the integration of heat prosumers has been slow in Sweden. Our current study investigates the drivers and barriers for prosumer integration in the ...

Abstract A simple and potentially inexpensive implementation of a high‐solids reactor is a single‐stage, stratified bed reactor, in which the bed is made up of the plant biomass fed into the system. In the present study, the stratified bed was started up for a period of four weeks by either direct feeding of sugar beet leaves at four different feeding rates, or by introducing a straw bed primer which was batch digested without feeding. During weeks five to six both systems were fed with sugar beet ...
