ABSTRACT Using consensus regions in gene sequences encoding the two forms of nitrite reductase (Nir), a key enzyme denitrification pathway, we designed sets PCR primers to amplify cd 1 - and Cu- nir . The were evaluated by screening defined denitrifying strains, isolates from wastewater treatment plants, extracts activated sludge. Sequence relationships genes also established. 778 799-bp region -nir six published sequences. Likewise, Cu amplified 473-bp seven eight Together, nine species...
Binding of cells Staphylococcus aureus to fibronectin, which may represent a mechanism host tissue adherence, involves fibronectin-receptor protein present on the bacterial surface. Cloning gene coding for staphylococcal fibronectin-binding and construction fusion with properties was previously reported from our laboratory. We have now sequenced deduced primary sequence protein. The resembles other cell-wall-associated proteins Gram-positive bacteria in that it (i) appears be anchored cell...
Antibiotic resistance (AR) is a global phenomenon that has severe epidemiological ramifications world-wide. It been suggested antibiotics have discharged into the natural aquatic environments after usage or manufacture can promote occurrence of antibiotic genes (ARG). These environmental ARGs could serve as reservoir and be horizontally transferred to human-associated bacteria thus contribute AR proliferation. The aim this study was investigate anthropogenic load in Northern Pakistan...
ABSTRACT Real-time PCR was used to quantify populations of ammonia-oxidizing bacteria representing the β subdivision class Proteobacteria in samples arable soil, both nitrogen fertilized and unfertilized, from Mellby, Sweden. Primers probes targeting a 16S ribosomal DNA region were designed used. In soil there ∼6.2 × 10 7 per g three times more than number unfertilized soil. The lytic efficiency bead beating these soils investigated by using free or loosely attached bacteria, tightly bound...
Antibiotic-resistant bacteria are an emerging global problem that threatens to undermine important advances in modern medicine. The environment is likely play role the dissemination of antibiotic-resistance genes (ARGs) among both environmental and pathogenic bacteria. Wastewater treatment plants (WWTPs) accumulate chemical biological waste from surrounding urban milieu have therefore been viewed as potential hotspots for development antibiotic resistance. To assess effect wastewater...
Information about norovirus (NoV) infections in Central America is limited. Through a passive community and hospital pediatric diarrhea surveillance program, total of 542 stool samples were collected between March 2005 February 2006 León, Nicaragua. NoV was detected 12% (65/542) the children; these, 11% (45/409) 15% (20/133) hospital, with most strains (88%) belonging to genogroup II. age gender associated, children <2 years (P < 0.05) girls being affected. Breast-feeding did not reduce...
The common tick Ixodes ricinus is the main vector in Europe of tick-borne encephalitis virus and several species Borrelia burgdorferi sensu lato complex, which are etiological agents Lyme borreliosis. risk to contract bites I. dependent on many factors including behaviour both ticks people. tick's site attachment human body duration may be clinical importance. Data ticks, were found attached skin people, analysed regarding potentially stage-specific differences location sites, (= feeding...
ABSTRACT Members of the genus Borrelia are among most common infectious agents causing tick-borne disease in humans worldwide. Here, we developed a Light Upon eXtension (LUX) real-time PCR assay that can detect and quantify species ticks have fed on humans, applied to 399 such ticks. PCR-positive were identified level by sequencing products conventional performed using group-specific primers. There was 19% prevalence spp. detached ticks, number spirochetes per tick ranged from 2.0 × 10 2 4.9...
A few billion birds migrate annually between their breeding grounds in Europe and wintering Africa. Many bird species are tick-infested, as a result of innate migratory behavior, they contribute significantly to the geographic distribution pathogens, including spotted fever rickettsiae. The aim present study was characterize, samples from two consecutive years, potential role migrant captured disseminators Rickettsia-infected ticks. Ticks were collected total 14,789 during seasonal migration...
The incidence of Lyme borreliosis (LB) in a region may reflect the prevalence Borrelia tick population. Our aim was to investigate if regions with different LB incidences can be distinguished by studying and diversity species their respective populations. load feeding increases duration feeding, which facilitate transmission Spirochetes from host. Therefore, we also wanted how ticks that have fed on humans varies feeding. During 2008 2009, had bitten were collected four Sweden Finland,...
Abstract Background Birds can act as reservoirs of tick-borne pathogens and also disperse pathogen-containing ticks to both nearby remote localities. The aims this study were estimate tick infestation patterns on migratory birds the prevalence different Borrelia species encephalitis virus (TBEV) in removed from south-eastern Sweden. Methods Ticks collected resident captured at Ottenby Bird Observatory, Öland, Sweden, March November 2009. molecularly identified species, morphologically...

Summary The effect of environmental conditions, especially ammonium concentration, on community composition and nitrification activity nitrifying bacterial biofilms in a pilot wastewater treatment plant was examined. A decreasing gradient created when four aerated tanks with suspended carrier material were serially fed wastewater. Community analysed using fluorescence situ hybridization (FISH) probes as well partial 16S rRNA amoA gene analysis polymerase chain reaction‐denaturating gel...
Aims: (i) To cultivate methicillin-resistant Staphylococcus aureus (MRSA) from a full-scale wastewater treatment plant (WWTP), (ii) characterize the indigenous MRSA-flora, (iii) investigate how process affects clonal distribution and (iv) examine genetic relation between MRSA clinical MRSA. Methods: Wastewater samples were collected during 2 months at four key sites in WWTP. isolates characterized using spa typing, antibiograms, SSCmec typing detection of Panton–Valentine leukocidin (PVL)....
To monitor emissions of NH(3) and N(2)O during composting link these to ammonia oxidation rates the community structure oxidizing bacteria (AOB).A laboratory-scale compost reactor treating organic household waste was run for 2 months. peaked when pH started increase. Small amounts CH(4) were also produced. In total, 16% less than 1% initial N lost as NH(3)-N N(2)O-N respectively. The potential rate, determined by a chlorate inhibition assay, increased fourfold first 9 days then remained...
The risk of developing Lyme borreliosis (LB) from Borrelia burgdorferi sensu lato (Bb)-infected ticks in Sweden is largely unknown. In the current study, we investigated prevalence Bb that had bitten humans and LB Bb-infected ticks.Health questionnaires, blood samples, were collected 394 tick-bitten study subjects County Östergötland, Sweden, at time tick bite. Questionnaires samples also 3 months later. Ticks screened for DNA with PCR, while sera analyzed antibodies against using two ELISA...
