Detection of the agent of human granulocytic ehrlichiosis (HGE) in UK ticks using polymerase chain reaction. (1/737)

Nymphal Ixodes ricinus ticks collected from woodland areas in South Wales, UK, were tested using the polymerase chain reaction for the presence both of the causative agent of human granulocytic ehrlichiosis (HGE) and Borrelia burgdorferi. Twenty-two of 60 (37%) ticks were found positive in the PCR for B. burgdorferi and 4/60 (7%) for the HGE agent. One tick was found positive both for B. burgdorferi and HGE agent. Our findings imply the presence of the HGE agent in UK ticks and the finding of a tick apparently containing both pathogens underlines the potential for concurrent infection with HGE agent and B. burgdorferi to occur after a single tick-bite. Based on our observations, we conclude that there may be a need to consider a range of pathogens both in laboratory investigation and clinical management of suspected tick-borne disease in the UK, particularly where there is a clinical presentation atypical of Lyme borreliosis alone.  (+info)

Isolation of Lyme disease Borrelia from puffins (Fratercula arctica) and seabird ticks (Ixodes uriae) on the Faeroe Islands. (2/737)

This is the first report on the isolation of Lyme disease Borrelia from seabirds on the Faeroe Islands and the characteristics of its enzootic cycle. The major components of the Borrelia cycle include the puffin (Fratercula arctica) as the reservoir and Ixodes uriae as the vector. The importance of this cycle and its impact on the spread of human Lyme borreliosis have not yet been established. Borrelia spirochetes isolated from 2 of 102 sampled puffins were compared to the borreliae previously obtained from seabird ticks, I. uriae. The rrf-rrl intergenic spacer and the rrs and the ospC genes were sequenced and a series of phylogenetic trees were constructed. Sequence data and restriction fragment length polymorphism analysis grouped the strains together with Borrelia garinii. In a seroepidemiological survey performed with residents involved in puffin hunting on the Faeroe Islands, 3 of 81 serum samples were found to be positive by two commonly used clinical tests: a flagellin-based enzyme-linked immunosorbent assay (ELISA) and Western blotting. These three positive serum samples also had high optical density values in a whole-cell ELISA. The finding of seropositive Faeroe Islanders who are regularly exposed to I. uriae indicate that there may be a transfer of B. garinii by this tick species to humans.  (+info)

Quantitative real-time PCR for detection of members of the Ehrlichia phagocytophila genogroup in host animals and Ixodes ricinus ticks. (3/737)

A TaqMan PCR was established for identification and quantitation of members of the Ehrlichia phagocytophila group in experimentally infected cows and in Ixodes ricinus ticks. The TaqMan PCR identified a 106-bp section of the 16S rRNA gene by use of a specific fluorogenic probe and two primers. This technique was specific for members of the E. phagocytophila group, which include E. phagocytophila, Ehrlichia equi, and the agent of human granulocytic ehrlichiosis. The TaqMan system identified 10 copies of a cloned section of the 16S rRNA gene of E. phagocytophila. The sensitivity and specificity of the TaqMan PCR were similar to those of conventional nested PCR. The numbers of ehrlichiae in leukocytes of the two cows experimentally infected with E. phagocytophila were measured daily by TaqMan PCR and had a course similar to that of the percentages of infected leukocytes determined daily by light microscopy. The prevalence of infected free-living ticks, which were collected from areas where bovine ehrlichiosis is endemic and from regions with sporadic occurrences of granulocytic ehrlichiosis in dogs and horses, was identical as determined by nested PCR and TaqMan PCR.  (+info)

Evidence of the human granulocytic ehrlichiosis agent in Ixodes ricinus ticks in Switzerland. (4/737)

A total of 1,667 Ixodes ricinus ticks were collected from five regions in Switzerland where there have been sporadic occurrences of granulocytic ehrlichiosis in dogs and horses. The ticks were examined for rickettsiae of the Ehrlichia phagocytophila group via nested PCR. Twenty-one ticks (1.3%) were positive; 3 (0.5%) were nymphs, 6 (1.3%) were adult males, and 12 (1.9%) were adult females. The number of positive ticks varied with the stage of development and with the geographical origin. Nucleotide sequencing of the isolated PCR products identified these products as part of the 16S rRNA gene of Ehrlichia. In addition, these products had 100% homology with the agent of human granulocytic ehrlichiosis. The occurrence of this agent in I. ricinus in Switzerland presents a potential danger of transmission of granulocytic ehrlichiosis to dogs, horses, and humans.  (+info)

Prevalence of Borrelia burgdorferi in Ixodes ricinus ticks in urban recreational areas of Helsinki. (5/737)

Lyme borreliosis, an infection caused by the tick-borne spirochete Borrelia burgdorferi, is a major health problem for populations in areas of endemicity in the Northern Hemisphere. In the present study we assessed the density of ticks and the prevalence of B. burgdorferi sensu lato among ticks in popular urban recreational areas of Helsinki, Finland. Altogether 1,688 Ixodes ricinus ticks were collected from five areas located within 5 km of the downtown section of Helsinki, and 726 of them (303 nymphs, 189 females, and 234 males) were randomly chosen for laboratory analysis. The midguts of the ticks were divided into three pieces, one for dark-field microscopy, one for cultivation in BSK-II medium, and one for PCR analysis. Ticks were found in all the study areas; their densities varied from 1 to 36 per 100 m along which a cloth was dragged. The rate of tick infection with B. burgdorferi sensu lato varied from 19 to 55%, with the average being 32%. Borellia afzelii was the most predominant genospecies in all the areas, and no B. burgdorferi sensu stricto isolates were detected. Only two ticks were concurrently infected with both B. afzelii and Borrelia garinii. Dark-field microscopy gave more positive results for B. burgdorferi than did cultivation or PCR analysis. However, the agreement between all three methods was fairly good. We conclude that Lyme borreliosis can be contracted even in urban environments not populated with large mammals like deer or elk. The disease should be taken into account in the differential diagnosis of certain symptoms of patients from these areas, and the use of measures to improve the awareness of the general population and health care officials of the risk of contracting the disease is warranted.  (+info)

Temporal relation between Ixodes scapularis abundance and risk for Lyme disease associated with erythema migrans. (6/737)

Understanding the role that nymphal and female ticks, Ixodes scapularis, have in the epidemiology of Lyme disease is essential to the development of successful prevention programs. In this study, the authors sought to evaluate the seasonal and annual relations between tick densities and patients > or = 16 years of age diagnosed with erythema migrans (EM), the rash associated with early Lyme disease. Ticks were collected weekly by drag sampling throughout most of the year from 1991 to 1996 in Westchester County, New York. The number of EM cases was based on patients diagnosed at the Westchester County Medical Center using Centers for Disease Control and Prevention (CDC) criteria. No patients with EM were diagnosed from January through April, when only adult ticks were active. Correlation analysis between monthly tick densities and EM incidence was significant for nymphs (r = 0.87, p < 0.01), but not for adult ticks (r = -0.57, p > 0.05). There was a strong, although not significant, correlation between peak annual number of patients with EM and peak nymphal tick abundance (r = 0.76, p = 0.08). These data indicate that bites from adult I. scapularis only rarely result in Lyme disease, and that annual nymphal tick abundance determines exposure. This suggests that annual fluctuations in Lyme disease case numbers are largely due to natural changes in tick abundance and, therefore, that control of nymphal I. scapularis should be a major component of Lyme disease prevention efforts.  (+info)

Antibody levels to recombinant tick calreticulin increase in humans after exposure to Ixodes scapularis (Say) and are correlated with tick engorgement indices. (7/737)

The antibody responses of subjects who presented with a definite Ixodes scapularis (Say) tick bite were measured to determine the utility of the antibody response against recombinant tick calreticulin (rTC) as a biologic marker of tick exposure. Subjects bitten by I. scapularis evidenced an increase in anti-rTC antibody levels between visit 1 and visit 2 from 24.3 to 27.1 ng/microl serum (n = 88, p = 0.003), and levels remained elevated at visit 3 (p = 0.005). These anti-rTC antibody levels during visits 2 and 3 were significantly higher than those in four non-exposed controls. Tick engorgement indices, measured on the biting ticks, were found to be correlated with anti-rTC antibody levels (e.g., for visit 3: Pearson's r = 0.357, p = 0.001). Tick engorgement index (TEI), ratio of body length to scutal width, was identified to be the only independent predictor of anti-rTC antibody levels in linear regression models. Logistic regression revealed that a bite from an I. scapularis tick that became engorged (TEI >3.4) was a risk factor for anti-rTC antibody seropositivity (adjusted odds ratio for age and bite location = 7.4 (95% confidence interval 2.1-26.4)). The anti-rTC antibody test had a sensitivity of 0.50 and a specificity of 0.86 for a bite from I. scapularis that became engorged. Immunoblotting revealed that subjects made a specific anti-rTC antibody response.  (+info)

Disparity in the natural cycles of Borrelia burgdorferi and the agent of human granulocytic ehrlichiosis. (8/737)

We studied the prevalence of Borrelia burgdorferi and the agent of human granulocytic ehrlichiosis (HGE) among questing nymphal and adult Ixodes scapularis ticks of the same generation and the infectivity of wild white-footed mice for ticks feeding on them. The prevalence of B. burgdorferi infection in host-seeking ticks increased less than twofold from nymphal (31% to 33%) to adult (52% to 56%) stage, and 52% of white-footed mice were infected. Prevalence of the agent of HGE increased 4.5- to 10.6-fold from nymphal (1.5% to 1.8%) to adult stage (7.6% to 19.0%), while only 18% of mice were infectious to ticks. B. burgdorferi infection was more common in mouse-fed ticks than in ticks collected from vegetation, whereas the agent of HGE was half as common in mouse-fed ticks as in ticks collected from vegetation. The different prevalence in nature of these pathogens in ticks suggests that their maintenance cycles are also different.  (+info)

The distributional area of the tick Ixodes ricinus (L.), the primary European vector to humans of Lyme borreliosis spirochaetes (Borrelia burgdorferi sensu lato) and tick-borne encephalitis virus, appears to be increasing in Sweden. It is therefore important to determine which environmental factors are most useful to assess risk of human exposure to this tick and its associated pathogens. The geographical distribution of I. ricinus in Sweden was analysed with respect to vegetation zones and climate. The northern limit of I. ricinus and B. burgdorferi s.l. in Sweden corresponds roughly to the northern limit of the southern boreal vegetation zone, and is characterized climatically by snow cover for a mean duration of 150 days and a vegetation period averaging 170 days. The zoogeographical distribution of I. ricinus in Sweden can be classified as southerly-central, with the centre of the distribution south of the Limes Norrlandicus. Ixodes ricinus nymphs from 13 localities in different parts of ...
It was recently demonstrated that the lone star tick Amblyomma americanum could harbor filarial nematodes within the genus Acanthocheilonema. In this study, Ixodes scapularis (deer) ticks collected from Southern Connecticut were evaluated for their potential to harbor filarial nematodes. Non-engorged nymphal and adult stage Ixodes scapularis ticks were collected in Southern Connecticut using the standard drag method. In situ hybridization with filarial nematode specific sequences demonstrated the presence of filarial nematodes in Ixodes ticks. Filarial nematode specific DNA sequences were amplified and confirmed by direct sequencing in Ixodes nymphal and adult ticks using either general filarial nematode or Onchocercidae family specific PCR primers. Phylogenetic analysis of the 12S rDNA gene sequence indicated that the filarial nematode infecting Ixodes scapularis ticks is most closely related to the species found in Amblyoma americanum ticks and belongs to the genus of Acanthocheilonema.

During previous studies we have described the major constituents of the digestive machinery of the hard tick I. ricinus and deciphered how they are organized into a hemoglobinolytic pathway [8, 12]. Herein, we have focused on the dynamic profiling of the components of the tick digestive apparatus during the course of tick feeding. This information is particularly relevant since the feeding phase is decisive for pathogen transmission. We have provided a comprehensive insight into the gene transcription, activity and molar concentration of five digestive enzymes during blood feeding, as well as the localization of the IrCB, as the most abundant peptidase of the pathway. Placing these molecular data into the context of previous ultrastructural and histochemical studies on tick gut development performed in 1970s and 80s [3, 13, 18] improves significantly our understanding of the entire process of intracellular blood digestion.. Morphological changes of the midgut epithelium observed during blood ...
Abstract: The objective of the study was to determine the prevalence rate of 3 Borrelia burgdorferi genospecies in Ixodes ricinus ticks collected from wooded areas of the Lublin region (eastern Poland). A group of 1,813 I. ricinus ticks from 6 districts were examined for the presence of Borrelia burgdorferi sensu lato (B.b. s.l.) by polymerase chain reaction (PCR). Another group of 438 I. ricinus ticks collected from 4 districts were examined for the presence of B.b. s.l. by culture on BSKH liquid medium confirmed by PCR, and for the presence of Borrelia spp. by dark field microscopy (DFM). Borrelia burgdorferi genospecies (Borrelia burgdorferi sensu stricto, Borrelia afzelii and Borrelia garinii) were determined by nested-PCR in 113 ticks lysates showing presence of B.b. s.l. (in PCR or in culture and PCR). 5.4% of I. ricinus ticks examined by PCR showed the presence of B.b. s.l. DNA. The infection rate was highest in females (12.1%), lower in males (6.0%) and the lowest in nymphs (1.7%) ...
I. persulcatus ticks transmit Lyme disease, babesiosis, and Siberian (TBEV-Sib) and Far Eastern (TBEV-FE) tick-borne encephalitis,[1][4] and probably human granulocytic anaplasmosis as well.[5] A recent study of the northernmost tick-borne encephalitis focus in Simo, Finnish Lapland, found I. persulcatus ticks in scattered foci along the western coast, including the Kokkola archipelago and Närpes municipality, demonstrating a northward movement of foci and an unusual combination of the TBEV-Eur strain and I. persulcatus ticks in an area with no evidence of cocirculation of tick species or TBEV subtypes.[1] ...
Lyme borreliosis is an emerging tick-borne disease caused by spirochetes Borrelia burgdorferi sensu lato. In Europe, Lyme borreliosis is predominantly caused by Borrelia afzelii and transmitted by Ixodes ricinus. Although Borrelia behavior throughout tick development is quite well documented, specific molecular interactions between Borrelia and the tick have not been satisfactorily examined. Here,...
The authors also presented several lines of evidence supporting the adaptive function of dae genes transferred to the black-legged tick* (Ixodes scapularis) a vector for Borrelia burgdorferi, which causes Lyme disease: i) the dae2 gene is expressed in nymph and adult phases of the deer tick, ii) Dae2, a protein isolated from the tick, is found in tick salivary glands and the mid-gut, locations where the B. burgdorferi would be encountered by the tick during transmission of the bacteria via a blood meal, iii) Dae2 proteins isolated from the tick have antimicrobial properties (more specifically, the proteins can degrade bacterial cell walls). Essentially, dae2 contributes to the innate ability of the tick to control B. burgdorferi levels after infection ...

Ixodes ricinus ticks collected from the North Sea Island of Ameland, the Netherlands, were screened for the presence of Borrelia spirochaetes. The present authors used IFAT on tick gut preparations and identified Borrelia in 31 per cent of the adult ticks and 16 per cent of the nymphs collected from the dunes and 45 per cent of the nymphs collected from the forests. In vitro cultivation of Borrelia sp. isolated from the adult ticks and its subsequent recognition by B. burgdorferi-specific monoclonal antibodies in western blots, verified that this pathogen is identical with B. burgdorferi, the causative agent of Lyme Disease. Further research is required to gain an insight into the epidemiology of the disease and to assess its medical and veterinary significance in the Netherlands.
We present observational and experimental evidence that cycles of the Lyme disease spirochaete, Borrelia burgdorferi s.l., can be maintained by sheep in the virtual absence of alternative hosts. A 2-year field study in upland moorland habitats of northwest UK established that sheep feed up to 80% of larval, | 99% of nymphal and all of the adult female tick (Ixodes ricinus) population. Infection prevalence of B. burgdorferi in questing ticks reaches over 20%, but amplification of infection occurs principally as nymphs (20- to 30-fold), rather than larvae (4- to 7-fold), feed on sheep, and transmission from sheep to ticks occurred only during peak tick abundance in May and September. Experimental transmission studies confirmed that sheep, previously exposed to infected ticks on the moorland site, do not support systemic infections of B. burgdorferi, but they can transmit localized infections from infected to uninfected ticks co-feeding at the same site on the sheeps body.
Our understanding of tick questing behaviour is limited by the difficulty of observing ticks without disturbing them. As humans are potential hosts for I. ricinus, the presence of an observer may influence tick behaviours (McMahon and Guerin, 2002). Due to the small size of I. ricinus nymphs, their movements are particularly difficult to study, so most studies on I. ricinus questing behaviour have focused on adults (Gigon, 1985). Tick behaviours last many hours or even days and so continuous observation of single individuals over several days is hardly possible without automation. Furthermore, humans are not able to see ticks in the dark. For these reasons, we developed an automated video-tracking system to record the movements of I. ricinus nymphs continuously, independent of any potential host stimuli and under both light and dark conditions. Using this system, we show that questing and quiescence behaviours of I. ricinus alternate in the absence of any host stimuli. Lees (1946) had already ...

Tickborne fever (TBF) is a febrile disease of domestic and free-living ruminants in the temperate regions of Europe. TBF is prevalent in sheep and cattle in the UK, Ireland, Norway, Finland, The Netherlands, Austria, and Spain. It is transmitted by the hard tick Ixodes ricinus . A similar disease transmitted by other ticks has been described in India and South Africa. The main hosts are sheep and cattle, but goats and deer are also susceptible.. After infestation with infected ticks, the incubation period may be 5-14 days, but after injection with infected blood, the incubation period is 2-6 days. In sheep, the main clinical sign is a sudden fever (105-108°F [40.5-42.0°C]) for 4-10 days. Other signs are either absent or mild, but the animals generally appear dull and may lose weight. Respiratory and pulse rates are usually increased, and a cough often develops.. In cattle, the disease is known as pasture fever in many parts of Europe, including Finland, Norway, Austria, Spain, and Switzerland. ...
Nymphs from each of the four populations were put in tubes made from nylon mesh (250 μm diameter) that were 3 cm diameter, 13 cm high and glued at the base to a 3 cm diameter Petri dish. Each tube was filled with 1.5 cm of wet sand, then 1 cm of damp moss, to provide a moist environment where ticks could rehydrate if necessary as they would in nature. Immediately after adding the ticks, the tops of the tubes were sealed. Twelve tubes, each with 30 nymphs (i.e., 360 nymphs in total per site), were used for each population, except for the North Wales population that had 10 tubes (i.e., 300 nymphs in total) due to fewer ticks collected from that site.. The mesh tubes containing ticks from the UK sites were allocated equally between two portable incubators (Memmert IPP 200; Memmert, Schwabach, Germany). In order to control for any potential variation in conditions between the two incubators, an equal proportion of tubes from each population were allocated to each incubator, and the temperature and ...
Borrelia miyamotoi sensu lato relapsing fever group spirochetes are emerging as causative agents of human illness (Borrelia miyamotoi disease) in the United States. Host-seeking Ixodes scapularis ticks are naturally infected with these spirochetes in the eastern United States and experimentally capable of transmitting B. miyamotoi. However, the duration of time required from tick attachment to spirochete transmission has yet to be determined. We therefore conducted a study to assess spirochete transmission by single transovarially infected I. scapularis nymphs to outbred white mice at three time points post-attachment (24, 48, and 72h) and for a complete feed (>72-96h). Based on detection of B. miyamotoi DNA from the blood of mice fed on by an infected nymph, the probability of spirochete transmission increased from 10% by 24h of attachment (evidence of infection in 3/30 mice) to 31% by 48h (11/35 mice), 63% by 72h (22/35 mice), and 73% for a complete feed (22/30 mice). We conclude that (i) ...
A mathematical model of enzootic Lyme-disease transmission in a natural focus is presented. This model is based on the life history of the vector tick Ixodes scapularis Say and the primary reservoir host Peromyscus leucopus. Using this model, the threshold condition for the disease to be able to invade a nonenzootic region is determined as a function of the various possible transmission chains operating throughout the year. These expressions show that the transmission chain in which ticks acquire the disease from mice in the fall and transmit it back to mice as nymphs in the spring is the most important chain (contributing approximately 87% of the elasticity of the threshold for the parameter choices examined). Equilibrium disease levels were examined under the assumption of a constant tick population; these levels were determined as a function of tick and mouse density, the vertical transmission rate, the infectivity of mice, and the survivorship parameters of the ticks and of the tick-host contact

We observed wide variations in the prevalence of tick-borne bacteria in I. ricinus ticks in a French bocage landscape. This prevalence was influenced by several environmental factors that varied according to the bacterial species and habitat type. Depending on the habitat and the stage and sex of the adult tick, we found that 1.4% to 16.1% of the ticks carried DNA of at least one of the three bacteria studied. Compared to the rates found in Europe (51) and France (5, 50), the infection prevalences that we found for B. burgdorferi sensu lato are low. This could be due to the inclusion in our study of pastures, where there was a lower infection prevalence, whereas most studies carried out in Europe focus on woody habitats. For A. phagocytophilum, our figures are higher than the figures previously reported in France (5, 27), but they fall within the range of figures found in other European sites (30, 34), including some that considered woodlands and pastures (39, 66). For Rickettsia sp., the ...
Rapid and reliable identification of the vertebrate species on which a disease vector previously parasitized is imperative to study ecological factors that affect pathogen distribution and can aid the development of public health programs. Here we describe a proteome profiling technique designed to identify the source of blood meals of haematophagous arthropods. This method employs direct spectral matching and thus does not require a priori knowledge of any genetic or protein sequence information. Using this technology, we detect remnants of blood in blacklegged ticks (Ixodes scapularis) and correctly determine the vertebrate species from which the blood was derived, even 6 months after the tick had fed. This biological fingerprinting methodology is sensitive, fast, cost-effective and can potentially be adapted for other biological and medical applications when existing genome-based methods are impractical or ineffective ...

Various ticks exist in the temperate hilly and pre-alpine areas of Northern Italy, where Ixodes ricinus is the more important. In this area different tick-borne pathogen monitoring projects have recently been implemented; we present here the results of a twoyear field survey of ticks and associated pathogens, conducted 2009-2010 in North-eastern Italy. The cost-effectiveness of different sampling strategies, hypothesized a posteriori based on two sub-sets of data, were compared and analysed. The same two subsets were also used to develop models of habitat suitability, using a maximum entropy algorithm based on remotely sensed data. Comparison of the two strategies (in terms of number of ticks collected, rates of pathogen detection and model accuracy) indicated that monitoring at many temporary sites was more cost-effective than monthly samplings at a few permanent sites. The two model predictions were similar and provided a greater understanding of ecological requirements of I. ricinus in the ...

Robert-von-Ostertagstr. 7-13, 14163 Berlin. Supervisor: Dr. Sebastian Rausch and Prof. Dr. Susanne Hartmann. Project Description: Infections with parasitic nematodes and ticks induce strong local and systemic T helper type 2 (Th2) responses. Dendritic cells are central for the imprinting of the Th2 response in both infections, but innate Th2-associated cells such as mast cells and eosinophils are involved in instructing and regulating Th2 immune responses to nematodes. The aim of this project is to investigate whether mucosal/dermal mast cells and eosinophils affect the quality and homing capacity of Th cells imprinted by local DC populations in infections with the murine gut nematode Heligmosmoides polygyrus and the European tick Ixodes ricinus. Furthermore, the stability of migration patterns of parasite-specific Th2 cells will be assessed in nematode/tick co-infections.. Start: as soon as possible. Application Deadline: July 31st 2015.

The first thing they noticed was a fall. It happened without warning; there was nothing to trip over, no dizziness or fainting – just a sudden loss of balance and a backwards fall, hard enough to hit the wall and leave a mark. Hard enough to hurt.
Results: The DxI CA125 assay demonstrated an overall positive 29% bias relative to the Centaur CA125 assay. The DxI CA15-3 assay demonstrated an overall negative 65% bias relative to the Centaur CA27.29 assay. For patients with multiple comparisons during the study period, the trend of results over time was similar across both sets of assays. Implementing the manufacturer-recommended reference interval for the DxI CA125 assay increased the abnormal flagging rate by 4.5%. In contrast, implementing the manufacturer-recommended reference interval for the DxI CA15-3 assay decreased the abnormal flagging rate by 13.0%. ...
Despite the rise of resistant strains of bacteria fuelled by increased use of antibiotics, patent filings are flagging, writes Dr Paul Chapman
This paper highlights that the second part of 1992 has been characterized by flagging consumer and business confidence, weaker-than-expected economic activity-especially in Europe and Japan-and considerable tensions in foreign exchange markets. Despite encouraging signs of increased growth in the United States, these developments have cast new doubts on the prospects for recovery in the industrial world after what has already been two years of weak growth or recession in many countries. The persistent currency turbulence since September 1992 and growing tensions over trade have also contributed to increased uncertainty.
Barley grass is considered being the most effective method to regulate the PH from the body and prevent health problems since Barley grass not simply contains a volume of important nutrients and also contains high degrees of anti oxidants that could prevent possible health problems for example cancer or stroke. Please seek advice from your doctor before you start any new diet or workout. Finally should you make sure is organic and pesticide free then a experience with the dining table should grow more and even more every time you sit back with some succulent supplements. For example, holistic cat food, nutrition from organic and natural products and procedures, is a excellent selection for boosting the flagging energy associated with a cat, but especially a senior.

Please seek advice from your doctor before you start any new diet or workout. Finally should you make sure is organic and pesticide free then a experience with the dining table should grow more and even more every time you sit back with some succulent supplements. For example, holistic cat food, nutrition from organic and natural products and procedures, is a excellent selection for boosting the flagging energy associated with a cat, but especially a senior. It is since the better taste from the processed food required numerous toxic chemicals that need to be dangerous to your whole body. The Great Combo - This is my favorite since it works very well.

The Care Plan Topic is one of the roll outs of the Care Provision Domain Message Information Model (D-MIM). The Care Plan is a specification of the Care Statement with a focus on defined Acts in a guideline, and their transformation towards an individualized plan of care in which the selected Acts are added. The purpose of the care plan as defined upon acceptance of the DSTU materials in 2007 is: - To define the management action plans for the various conditions (for example problems, diagnosis, health concerns)identified for the target of care - To organize a plan for care and check for completion by all individual professions and/or (responsible parties (including the patient, caregiver or family) for decision making, communication, and continuity and coordination) - To communicate explicitly by documenting and planning actions and goals - To permit the monitoring, and flagging, evaluating and feedback of the status of goals, actions, and outcomes such as completed, or unperformed activities ...

A few months ago, I dissected a squid. The squid was unsurprisingly strange: all tentacles and ooze and sets of sharp hidden teeth. But the dissection was strange, too. The longer I dissected, the less clear my agenda seemed to be. I poked around in the squid with a flagging sense of purpose and the nagging feeling that I was missing something important. Im not sure what went awry, but I am unsettled. And I want something better to say. A few months ago, I cut open a gelatinous sea creature to take a look inside. What, exactly, was I doing?. But we all know what it means to dissect something. It is a procedure, a way of looking, an act of investigation. It is commonsense inquiry and theres no reason to be confused. If, at its conclusion, the squid is still foreign - and the encounter an unanswered question - then I must have done something wrong.. So I want to take another look, as a matter of pride. Ill marshal my best methodology. Im going to draw a slit down my dissection and put my ...

The aim of the present study was to compare different urban biotopes for the occurrence of ixodid tick species, for the population density of Ixodes ricinus and for the prevalence rates of two emerging, zoonotic pathogens. Altogether 2455 ticks were collected from the vegetation on 30 places (forests, parks, cemeteries) of Budapest, Hungary. I. ricinus and Haemaphysalis concinna were collected in all three biotope types, but Dermacentor reticulatus only in parks and forests, and D. marginatus only in a forest. Highest population density of I. ricinus was observed in neglected parts of cemeteries. In females of this tick species the prevalence rates of Anaplasma phagocytophilum and Borrelia burgdorferi s.l. were significantly lower in cemeteries, than in parks or forests. In conclusion, risks associated with the presence of ticks and tick-borne pathogens may be high in a city, but this depends on biotope types, due to habitat-related differences in the vegetation, as well as in the availability ...
Cattle grazing has been suggested to reduce the risk for Lyme borreliosis by decreasing the density of questing Ixodes ricinus infected with Borrelia burgdorferi sensu lato. We tested the hypotheses that cattle grazing used in woodland management decreases the density of questing I. ricinus, and that it decreases the nympal infection prevalence of B. burgdorferi sensu lato. We further expected the nympal infection prevalence of tick-borne pathogens that utilize cattle as amplifying hosts, namely Anaplasma phagocytophilum, and Babesia sensu stricto, to increase. To test these hypotheses, we compared the densities of questing I. ricinus between twenty pairs of plots in grazed and ungrazed forest areas. The density of I. ricinus adults, but not nymphs, was lower in areas grazed by cattle than in ungrazed areas. Nymphs were tested for the presence of Borrelia burgdorferi s.l., Borrelia miyamotoi, Anaplasma phagocytophilum, and Babesia s.s. DNA from twelve paired areas. Anaplasma phagocytophilum and ...

Partial migration is common among northern ungulates, typically involving an altitudinal movement for seasonally migratory individuals. The main driving force behind migration is the benefit of an extended period of access to newly emerged, high quality forage along the green up gradient with increasing altitude; termed the forage maturation hypothesis. Any other limiting factor spatially correlated with this gradient may provide extra benefits or costs to migration, without necessarily being the cause of it. A common ectoparasite on cervids in Europe is the sheep tick (Ixodes ricinus), but it has not been tested whether migration may lead to the spatial separation from these parasites and thus potentially provide an additional benefit to migration. Further, if there is questing of ticks in winter ranges in May before spring migration, deer migration may also play a role for the distribution of ticks. We quantified the abundance of questing sheep tick within winter and summer home ranges of migratory (n
A mechanistic model was developed for mainland Scotland to predict the seasonal dynamics of the B. burgdorferi s.l. infected nymphal I. ricinus ticks (or DIN), a biophysical risk indicator of Lyme disease. The model integrates recent advances in simulating the temperature-driven temporal [16-20] and spatial [21,22] dynamics of disease risk, with multi-disciplinary data based on the literature, empirical evidence, earth observation and model predictions. It was developed using an agent-based approach that consisted of three generalized grid layers (tick population, host population and landscape) and a range of transition rules describing their interactions under the influence of temperature. Considering the scale (the whole of mainland Scotland) and spatial resolution (1 km2) of this study, the model is more relevant for rodent-specialized Borrelia genospecies such as B. afzelii and B. burgdorferi s.s. than for the bird-specialized B. garinii or B. valaisiana because the densities of rodents are ...
The present study was conducted to specifically test the hypothesis that delivery of long dsRNA by electroporation can be used as a potentially high throughput tool for studying functional genomics in epidemiologically important life stages of I. scapularis. RNAi has become a powerful experimental tool for studies involving tick-host-pathogen interaction but its utility has been severely limited by the tedious and often traumatic nature of delivering dsRNA to tick nymphs or eggs by microinjection or capillary feeding [17, 18]. Therefore, improved delivery methods and optimized protocols for gene silencing in a ticks nymphal or egg stage would make RNAi more widely available to tick biologists and enhance future RNAi applications in tick-host-pathogen and high throughput tick genome research. I. scapularis nymphs are responsible for most human transmission of Lyme disease spirochetes, B. burgdorferi, and also transform to become either male or female adult ticks, making this stage a favored ...

How much are you and your family at risk for Lyme disease? This map shows an approximate distribution of predicted Lyme disease risk in the United States -- from high risk to the minimal/no risk zones.
Bacteria associated with the tick Ixodes ricinus were assessed in specimens unattached or attached to the skin of cats, dogs and humans, collected in the Czech Republic. The bacteria were detected by PCR in 97 of 142 pooled samples including 204 ticks, i.e. 1-7 ticks per sample, collected at the same time from one host. A fragment of the bacterial 16S rRNA gene was amplified, cloned and sequenced from 32 randomly selected samples. The most frequent sequences were those related to Candidatus Midichloria midichlori (71% of cloned sequences), followed by Diplorickettsia (13%), Spiroplasma (3%), Rickettsia (3%), Pasteurella (3%), Morganella (3%), Pseudomonas (2%), Bacillus (1%), Methylobacterium (1%) and Phyllobacterium (1 ...

In this research, QX200 Droplet Digital PCR (ddPCRTM) system protocols for the detection of bacterial (Borrelia burgdorferi and Borrelia miyamotoi) DNA were developed and tested. Existing Ixodes scapularis samples collected from Cape Cod, Massachusetts and previously determined to be 60% positive for B. burgdorferi were utilized to investigate absolute bacterial genome carriage per tick using the ddPCR assays optimized here. The ddPCR technology proved to be a reliable means for detection and absolute quantification of control bacterial DNA with sensitivity as low as 10 spirochetes per μl input DNA. Application of ddPCR revealed an average B. burgdorferi carriage level of 27,239 copies in infected ticks (range: 231- 118,407 copies), 2,197 copies in infected nymphs (range: 231- 4,983 copies), and 45,620 copies in infected adults (range: 5,647- 118,407 copies). This is the first known and validated application of ddPCR for the detection of Borrelia DNA in Ixodes ticks.

When your pet is spending much of the day outdoors, youll need to give him regular exams to make sure he hasnt befriended some ticks. Here are some tips to help.. First, its important to be able to identify these tiny parasites. Ticks are arachnids, like spiders, so they have eight legs. Many types of ticks are barely even the size of a pinhead. And its not just their size that makes them difficult to find-these tiny pests can be brown, black, or tan in color, blending in easily with fur. The deer tick, also known as the black-legged tick, is a dangerous species because it is a carrier of the bacteria that causes Lyme disease. These ticks are brown to brownish red in color and have a flattened appearance.. Now that you know what to look for, its time to get up close and personal with your pet. Make sure your dog-or cat-is calm and still. Its helpful to have a second person holding your four-legged friend in place. Once you get your pet to stay put, run your hands slowly over the fur ...
The risk of getting Lyme disease from a tick bite is very low. But its important to know about Lyme disease, especially if you live in certain areas.

In April, thousands gathered on the National Mall in Washington, D.C., to march for science, exhorting continued innovation and advocating for support despite growing skepticism.. Confidence has eroded due to flagging enthusiasm as public figures decry overwhelming evidence, using selected studies to repudiate the conclusions of the scientific community. This is exacerbated further by news media that often focus on breakthrough potential and fail to capture the uncertainty inherent in a single study. As a result, there is growing sentiment that biomedical research has failed to the deliver on the promise of new therapies. Many criticize scientists for an inability to translate initial findings into medicine.. It is therefore the responsibility of the scientific community to encourage direct outreach that emphasizes that theres no eureka in science; discovery is a deliberate process toward consensus practiced cooperatively by an entire community of researchers..

As Ive observed, the former causes the most problems. Sometimes the user is not quite right in making the recommendation (which is understandable if its a gray area area), and sometimes the user is dead wrong. This is why I stress the importance of getting familiar with CRs Help Center, especially before commenting. The OP will almost always take that advice and post on CR right away, even without reading the Help Center. We then have to tell them that their post is off-topic there, which could leave them disappointed. Of course, well have to correct the commenter(s) as well.. Flagging, on the other hand, is safer because the SO mods are the gateway to migration.

Barnitz said the biggest benefit of STOCKOSORB® is less labor needed once the roots get established in the growing medium.. We dont have to water as frequently, he said. Therefore, we dont run the risk of overwatering, reducing the risk of root and foliar diseases. The plants run dryer so there is more air in the growing mix so that the root system is stronger.. We dont have to water as often so were not overwatering. Until we start getting into the bright, warm conditions of mid-spring, anything we can do to reduce the amount of pressure on the plants is to our advantage.. Barnitz said another benefit of using STOCKOSORB® occurs when plants arrive at their next stop on the way to consumers.. Whether its at our wholesale facilities or our retail locations or our independent garden center customers, STOCKOSORB® provides us with a longer time between watering before the plants start flagging or wilting, he said.
