Cytokine gene expression by peripheral blood leukocytes in horses experimentally infected with Anaplasma phagocytophila. (1/299)

Human granulocytic ehrlichiosis (HGE), a tick-borne zoonosis, is caused by an obligatory intragranulocytic bacterium, the HGE agent, a strain of Anaplasma phagocytophila. The equine model of HGE is considered valuable in understanding pathogenic and immune mechanisms of HGE. In the present study, cytokine mRNA expression by peripheral blood leukocytes (PBLs) in horses was examined during the course of infection by intravenous inoculation of A. phagocytophila or by allowing feeding by infected ticks. The p44 genes encoding the major outer membrane protein P44s of A. phagocytophila were detected by PCR in PBLs of all four horses from 4 to 20 days postexposure. During the 20-day infection period, interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNF-alpha) mRNA expression was upregulated in PBLs of all four horses, and IL-8 mRNA expression was upregulated in three horses. Gamma interferon, IL-10, and IL-12 p35 mRNAs were weakly expressed in only one horse each. IL-2, IL-4, IL-6, and IL-12 p40 mRNA expression, however, could not be detected in the PBLs of any of the four horses. These results suggest that IL-1beta, TNF-alpha, and IL-8 generation during A. phagocytophila infection has a primary role in HGE pathogenesis and immunomodulation.  (+info)

Repression of rac2 mRNA expression by Anaplasma phagocytophila is essential to the inhibition of superoxide production and bacterial proliferation. (2/299)

Anaplasma phagocytophila, the etiologic agent of human granulocytic ehrlichiosis, is an emerging bacterial pathogen that invades neutrophils and can be cultivated in HL-60 cells. Infected neutrophils and HL-60 cells fail to produce superoxide anion (O(2)(-)), which is partially attributable to the fact that A. phagocytophila inhibits transcription of gp91(phox), an integral component of NADPH oxidase. cDNA microarray and RT-PCR analyses demonstrated that transcription of the gene encoding Rac2, a key component in NADPH oxidase activation, was down-regulated in infected HL-60 cells. Quantitative RT-PCR demonstrated that rac2 mRNA expression was reduced 7-fold in retinoic acid-differentiated HL-60 cells and 50-fold in neutrophils following A. phagocytophila infection. Rac2 protein expression was absent in infected HL-60 cells. Rac1 and Rac2 are interchangeable in their abilities to activate NADPH oxidase. HL-60 cells transfected to express myc-tagged rac1 and gp91(phox) from the CMV immediate early promoter maintained the ability to generate O(2)(-) 120 h postinfection. A. phagocytophila proliferation was severely inhibited in these cells. These results directly attribute the inhibition of rac2 and gp91(phox) transcription to the loss of NADPH oxidase activity in A. phagocytophila-infected cells and demonstrate its importance to bacterial intracellular survival.  (+info)

Roles of neutrophil beta 2 integrins in kinetics of bacteremia, extravasation, and tick acquisition of Anaplasma phagocytophila in mice. (3/299)

Tick saliva contains anti-inflammatory and immunosuppressive substances that facilitate blood feeding and enhance tick-vectored pathogen transmission, including Anaplasma phagocytophila an etiologic agent of granulocytic ehrlichiosis. As such, inflammation at a tick-feeding site is strikingly different than that typically observed at other sites of inflammation. Up-regulation of CD11b/CD18 occurs in host granulocytes following interaction or infection with A phagocytophila, and the absence of CD11b/CD18 results in early increases in bacteremia. We hypothesized that beta 2 integrin-dependent infection kinetics and leukocyte extravasation are important determinants of neutrophil trafficking to, and pathogen acquisition at, tick-feeding sites. A phagocytophila infection kinetics were evaluated in CD11a/CD18, CD11b/CD18, and CD18 knock-out mice using quantitative polymerase chain reaction (PCR) of blood, ticks, and skin biopsies in conjunction with histopathology. A marked increase in the rate of A phagocytophila infection of neutrophils and pathogen burden in blood followed tick feeding. Infection kinetics were modified by beta 2 integrin expression and systemic neutrophil counts. Significant neutrophil-pathogen trafficking was observed to both suture and tick sites. Despite the prominent role for beta 2 integrins in neutrophil arrest in flowing blood, successful pathogen acquisition by ticks occurred in the absence of beta 2 integrins. Establishment of feeding pools that rely less on leukocyte trafficking and more on small hemorrhages may explain the ready amplification of A phagocytophila DNA from ticks infested on CD11/CD18-deficient mouse strains.  (+info)

Antibiotic susceptibilities of Anaplasma (Ehrlichia) phagocytophilum strains from various geographic areas in the United States. (4/299)

We tested the antibiotic susceptibilities of eight strains of Anaplasma phagocytophilum (the agent of human granulocytic ehrlichiosis) collected in various geographic areas of the United States, including Minnesota, Wisconsin, California, and New York. The results are homogeneous and show that doxycycline, rifampin, and levofloxacin are the most active antibiotics against these strains in vitro.  (+info)

Seasonal dynamics of Anaplasma phagocytophila in a rodent-tick (Ixodes trianguliceps) system, United Kingdom. (5/299)

We investigated the reservoir role of European wild rodents for Anaplasma phagocytophila using polymerase chain reaction (PCR) analysis of blood collected from individually tagged rodents captured monthly over 2 years. The only tick species observed in the woodland study site was Ixodes trianguliceps, and ruminant reservoir hosts were not known to occur. A. phagocytophila infections were detected in both bank voles and wood mice but were restricted to periods of peak nymphal and adult tick activity. Most PCR-positive rodents were positive only once, suggesting that rodent infections are generally short-lived and that ticks rather than rodents may maintain the infection over winter. Bank voles were more likely to be PCR positive than wood mice, possibly because detectable infections are longer lived in bank voles. This study confirms that woodland rodents can maintain A. phagocytophila in Great Britain in the absence of other reservoir hosts and suggests that I. trianguliceps is a competent vector.  (+info)

Comparison of PCR assays for detection of the agent of human granulocytic ehrlichiosis, Anaplasma phagocytophilum. (6/299)

Expression of multiple outer membrane protein sequence variants from a single genomic locus of Anaplasma phagocytophilum. (7/299)

Anaplasma phagocytophilum is the causative agent of an emerging tick-borne zoonosis in the United States and Europe. The organism causes a febrile illness accompanied by other nonspecific symptoms and can be fatal, especially if treatment is delayed. Persistence of A. phagocytophilum within mammalian reservoir hosts is important for ensuring continued disease transmission. In the related organism Anaplasma marginale, persistence is associated with antigenic variation of the immunoprotective outer membrane protein MSP2. Extensive diversity of MSP2 is achieved by combinatorial gene conversion of a genomic expression site by truncated pseudogenes. The major outer membrane protein of A. phagocytophilum, MSP2(P44), is homologous to MSP2 of A. marginale, has a similar organization of conserved and variable regions, and is also encoded by a multigene family containing some truncated gene copies. This suggests that the two organisms could use similar mechanisms to generate diversity in outer membrane proteins from their small genomes. We define here a genomic expression site for MSP2(P44) in A. phagocytophilum. As in A. marginale, the msp2(p44) gene in this expression site is polymorphic in all populations of organisms we have examined, whether organisms are obtained from in vitro culture in human HL-60 cells, from culture in the tick cell line ISE6, or from infected human blood. Changes in culture conditions were found to favor the growth and predominance of certain msp2(p44) variants. Insertions, deletions, and substitutions in the region of the genomic expression site encoding the central hypervariable region matched sequence polymorphisms in msp2(p44) mRNA. These data suggest that, similarly to A. marginale, A. phagocytophilum uses combinatorial mechanisms to generate a large array of outer membrane protein variants. Such gene polymorphism has profound implications for the design of vaccines, diagnostic tests, and therapy.  (+info)

Anaplasma phagocytophilum reduces neutrophil apoptosis in vivo. (8/299)

Ovine neutrophils spontaneously underwent apoptosis during culture in vitro, as assessed by morphological changes and exposure of annexin V binding sites on their cell surfaces. The addition of conditioned medium from concanavalin A-treated ovine peripheral blood mononuclear cells (PBMC) could partially protect against this progression into apoptosis, but dexamethasone and sodium butyrate could not. Actinomycin D accelerated the rate at which ovine neutrophils underwent apoptosis. Neutrophils isolated from sheep experimentally infected with Anaplasma phagocytophilum showed significantly delayed apoptosis during culture ex vivo, and the addition of conditioned medium from PBMC to these cells could not delay apoptosis above the protective effects observed after in vivo infection. The ability of neutrophils from A. phagocytophilum-infected sheep to activate a respiratory burst was increased compared to the activity measured in neutrophils from uninfected sheep, but chemotaxis was decreased in neutrophils from infected sheep. These data are the first demonstration that in vivo infection with A. phagocytophilum results in changes in rates of apoptosis of infected immune cells. This may help explain how these bacteria replicate in these normally short-lived cells.  (+info)

Anaplasma phagocytophilum variants in sympatric red deer (Cervus elaphus) and sheep in southern Norway. - Semantic ScholarAnaplasma phagocytophilum variants in sympatric red deer (Cervus elaphus) and sheep in southern Norway. - Semantic Scholar
Infections by the ixodid tick-transmitted bacterial pathogen Anaplasma phagocytophilum are common in domestic ruminants and cervids in the coastal areas of southern Norway. Previous experimental work has shown that A. phagocytophilum strains recovered from red deer (Cervus elaphus) are infective in lambs, but epidemiological links between infections in red deer and sheep have yet to be established. To address this shortfall, the present study explores the genotypic relatedness between A. phagocytophilum strains infecting sympatric red deer and sheep. Blood from 32 lambs grazing on tick-infested pasture, and blood and tissues from 8 red deer shot in proximity to these pastures were collected during the summer and autumn of 2007. The presence of A. phagocytophilum in these samples was determined by PCR-based methods, and genotyping of detected strains was performed using comparative sequence analysis of 16S rDNA and msp4 fragments. A. phagocytophilum DNA was detected in 12 lambs and 7 red deer, 11 and 4

Anaplasma phagocytophilum in ticks in Slovenia | Parasites & Vectors | Full TextAnaplasma phagocytophilum in ticks in Slovenia | Parasites & Vectors | Full Text
Ticks and tick-borne diseases affect animal and human health worldwide. A vector of many diseases in Europe and Slovenia is Ixodes ricinus [1]. It can be found in the forest, in shrubby or wooded pastures and on surfaces with low vegetation [2]. Ticks feeding cycle includes three stages: larva, nymph and adult. I. ricinus feeds on livestock, deer, dogs and a wide variety of other species, including humans [2]. I. ricinus is a confirmed vector of the bacterium Anaplasma phagocytophilum [3]. The tick becomes infected as it feeds on an infected host. Anaplasmae are transmitted from stage to stage as the tick moults (trans-stadially), but not transovarially. No anaplasmae have been detected in unfed larvae so far [4]. A. phagocytophilum, the agent of granulocytic anaplasmosis, was formerly known as human granulocytic ehrlichiosis agent (HGE agent), Ehrlichia phagocytophila and E. equi [5]. A. phagocytophilum causes a disease with diverse clinical signs in various hosts from asymptomatic to ...

Anaplasma phagocytophilum is a zoonotic and obligate intracellular bacterium transmitted by ticks. In domestic ruminants, it is the causative agent of tick-borne fever, which causes significant economic losses in Europe. As A. phagocytophilum is difficult to isolate and cultivate, only nine genome sequences have been published to date, none of which originate from a bovine strain. Our goals were to; 1/ develop a sequencing methodology which efficiently circumvents the difficulties associated with A. phagocytophilum isolation and culture; 2/ describe the first genome of a bovine strain; and 3/ compare it with available genomes, in order to both explore key genomic features at the species level, and to identify candidate genes that could be specific to bovine strains. DNA was extracted from a bovine blood sample infected by A. phagocytophilum. Following a whole genome capture approach, A. phagocytophilum DNA was enriched 197-fold in the sample and then sequenced using Illumina technology. In total, 58.9%

Fourteen vertebrate species (10 mammals and 4 birds) were assessed for their ability to transmit Anaplasma phagocytophilum, the bacterium that causes human granulocytic anaplasmosis, to uninfected feeding ixodid ticks. Small mammals were most likely to infect ticks but all species assessed were capable of transmitting the bacterium, in contrast to previous findings.

Anaplasma phagocytophilum is currently regarded as a single species. However, molecular studies indicate that it can be subdivided into ecotypes, each with distinct but overlapping transmission cycle. Here, we evaluate the interactions between and within clusters of haplotypes of the bacterium isolated from vertebrates and ticks, using phylogenetic and network-based methods. The presence of A. phagocytophilum DNA was determined in ticks and vertebrate tissue samples. A fragment of the groEl gene was amplified and sequenced from qPCR-positive lysates. Additional groEl sequences from ticks and vertebrate reservoirs were obtained from GenBank and through literature searches, resulting in a dataset consisting of 1623 A. phagocytophilum field isolates. Phylogenetic analyses were used to infer clusters of haplotypes and to assess phylogenetic clustering of A. phagocytophilum in vertebrates or ticks. Network-based methods were used to resolve host-vector interactions and their relative importance in the

A TaqMan real-time PCR assay targeting the Anaplasma citrate synthase gene, gltA, was developed and used for detection of Anaplasma phagocytophilum in 765 Ixodes ricinus ticks collected from dogs and cats in northern Norway (n = 669) and Telemark county in southern Norway (n = 96). Among the ticks from northern Norway the prevalence of A. phagocytophilum was 3.0 %, while the prevalence in southern Norway was 2.1 % (p = 0.63). The gltA PCR assay showed a high analytical sensitivity (30 genomic units) and efficiency (98.5 %), and its utility in clinical diagnostics should be evaluated in future studies. This is the first report of A. phagocytophilum occurrence in ticks collected north of the Arctic Circle in Norway. The prevalence is comparable to that found in Telemark county in southern Norway.

In recent years, some tick-borne diseases such as anaplasmosis and ehrlichiosis became widespread worldwide, threatening the health of humans, domestic animals and wildlife. The aims of this study were to determine the presence of Anaplasma phagocytophilum, Ehrlichia canis, and Ehrlichia chaffeensis in 102 opossums (Didelphis spp.) and 44 owned free-ranging dogs in southeastern Mexico using a specific polymerase chain reaction (PCR). A. phagocytophilum was detected in opossums and dogs with a prevalence of 3 and 27%, respectively. E. canis was only present in 7% of dogs, while we didnt detect E. chaffeensis in any host. We report the first evidence of infections of A. phagocytophilum in Didelphis virginiana and D. marsupialis in Mexico. The infection rates and patterns we found of A. phagocytophilum suggest that dogs are more directly involved in the ecology of this pathogen than opossums. Despite the small prevalence found, our results are of public health concern because of the zoonotic capabilities

Transformation of Anaplasma phagocytophilum | BMC Biotechnology | Full TextTransformation of Anaplasma phagocytophilum | BMC Biotechnology | Full Text
Tick-borne pathogens cause emerging zoonoses, and include fastidious organisms such as Anaplasma phagocytophilum. Because of their obligate intracellular nature, methods for mutagenesis and transformation have not been available. To facilitate genetic manipulation, we transformed A. phagocytophilum (Ap) to express a green fluorescent protein (GFP) with the Himar1 transposase system and selection with the clinically irrelevant antibiotic spectinomycin. These transformed bacteria (GFP/Ap) grow at normal rates and are brightly fluorescent in human, monkey, and tick cell culture. Molecular characterization of the GFP/Ap genomic DNA confirmed transposition and the flanking genomic insertion locations were sequenced. Three mice inoculated with GFP/Ap by intraperitoneal injection became infected as demonstrated by the appearance of morulae in a peripheral blood neutrophil and re-isolation of the bacteria in culture.

In the United States, Ixodes scapularis ticks overwinter in the Northeast and Upper Midwest and transmit the agent of human granulocytic anaplasmosis, Anaplasma phagocytophilum, among other pathogens. We now show that the presence of A. phagocytophilum in I. scapularis ticks increases their ability to survive in the cold. We identified an I. scapularis antifreeze glycoprotein, designated IAFGP, and demonstrated via RNAi knockdown studies the importance of IAFGP for the survival of I. scapularis ticks in a cold environment. Transfection studies also show that IAFGP increased the viability of yeast cells subjected to cold temperature. Remarkably, A. phagocytophilum induced the expression of iafgp, thereby increasing the cold tolerance and survival of I. scapularis. These data define a molecular basis for symbiosis between a human pathogenic bacterium and its arthropod vector and delineate what we believe to be a new pathway that may be targeted to alter the life cycle of this microbe and its ...

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 ...

The genus Anaplasma consists of tick-transmitted obligate intracellular bacteria that invade white or red blood cells to cause debilitating and potentially fatal infections. A. phagocytophilum, a human and veterinary pathogen, infects neutrophils to cause granulocytic anaplasmosis. A. marginale invades bovine erythrocytes. Evidence suggests that both species may also infect endothelial cells in vivo. In mammalian and arthropod host cells, A. phagocytophilum and A. marginale reside in host cell derived pathogen-occupied vacuoles (POVs). While it was recently demonstrated that the A. phagocytophilum-occupied vacuole (ApV) intercepts membrane traffic from the trans-Golgi network, it is unclear if it or the A. marginale-occupied vacuole (AmV) interacts with other secretory organelles. Here, we demonstrate that the ApV and AmV extensively interact with the host endoplasmic reticulum (ER) in endothelial, myeloid, and/or tick cells.

Unexpected Tick-borne Illness Cropping Up in Northeastern U.S.Unexpected Tick-borne Illness Cropping Up in Northeastern U.S.
A tick-borne illness that presents with undifferentiated flu-like symptoms similar to those seen in patients with Lyme disease and other such ailments is cropping up in the Northeastern United States. According to a recent Annals of Internal Medicine article, two patients -- one a 61-year-old man in Massachusetts and the other an 87-year-old New Jersey man -- presented with signs and symptoms suggesting human granulocytic anaplasmosis, which is caused by the rickettsia-like bacterium Anaplasma phagocytophilum carried by deer ticks in that region. The presumptive diagnosis proved false, however.

Genomic insights into the Ixodes scapularis tick vector of Lyme diseaseGenomic insights into the Ixodes scapularis tick vector of Lyme disease
Ticks transmit more pathogens to humans and animals than any other arthropod. We describe the 2.1 Gbp nuclear genome of the tick, Ixodes scapularis (Say), which vectors pathogens that cause Lyme disease, human granulocytic anaplasmosis, babesiosis and other diseases. The large genome reflects accumulation of repetitive DNA, new lineages of retro-transposons, and gene architecture patterns resembling ancient metazoans rather than pancrustaceans. Annotation of scaffolds representing similar to 57\% of the genome, reveals 20,486 protein-coding genes and expansions of gene families associated with tick-host interactions. We report insights from genome analyses into parasitic processes unique to ticks, including host `questing, prolonged feeding, cuticle synthesis, blood meal concentration, novel methods of haemoglobin digestion, haem detoxification, vitellogenesis and prolonged off-host survival. We identify proteins associated with the agent of human granulocytic anaplasmosis, an emerging disease, ...

Effects of cattle grazing on Ixodes ricinus-borne disease risk in forest areas of the Netherlands - WUREffects of cattle grazing on Ixodes ricinus-borne disease risk in forest areas of the Netherlands - WUR
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 ...

Abstract. Human granulocytic anaplasmosis (HGA) is a tick-borne infectious disease caused by Anaplasma phagocytophilum, an obligate intracellular bacterium. Until now, the utility of tick-bite site samples for HGA diagnosis has not been reported. Using a patient's buffy coat and tick-bite site crust samples, we performed polymerase chain reaction (PCR) testing using Ehrlichia- or Anaplasma-specific primers. PCR with buffy coat and crust samples obtained before doxycycline administration was positive. Six days after doxycycline administration, PCR with the buffy coat sample was negative but PCR with a crust tissue sample from the tick-bite site remained positive. This is the first case to suggest that crust tissue at the tick-bite site may be useful for early HGA diagnosis in patients who have already been treated with antibiotics such as doxycycline.

Interpretation of doxycycline+chloroquine dual therapy for A. phagocytophilum infection in dogsInterpretation of doxycycline+chloroquine dual therapy for A. phagocytophilum infection in dogs
DISCUSSION. A. phagocytophilum, capable of infecting granulocytes, and so far neutrophils and eosinophils (7), frequently cause an acute febrile systemic illness, namely CGA. In an attempt to make precise diagnostic tests for CGA microscopic detection of specific morulae, anti-Anaplasma IgM and IgG antibody detection and PCR analysis, which is most reliable for early diagnosis (8).. Recent exposure to A. phagocytophilum may be determined in dogs and human by acute and convalescent serologic testing, to those of IFA assays (9). IgG class antibodies primarily are detectable following 8 days after first exposure, corresponding to 2-5 days after morulae presence. It is therefore may be suggested that antibody detection may not be possible during acute infection (7). Seronegative dogs could probably have been recently infected; indeed a seropositive case could have been exposed to the etiological agent preceeding months, in association with elimination of infection thorugh immunity (10). Polymerase ...

PMN are endowed with a highly efficient adhesion and migratory apparatus that supports their primary function of rapid antimicrobial response during host defense. They have evolved a capacity for rapid activation of integrins that support the transition from cell rolling to arrest and transmigration on inflamed endothelium under the hydrodynamic shear of blood flow. One such process involves recognition of sLex-decorated receptors including L-selectin and PSGL-1 that redistribute and cluster at the trailing edge of a rolling PMN (36). This in turn triggers a cascade of intracellular signaling events including calcium flux, phosphorylation of MAPK, an upshift in integrin affinity, and shear-resistant adhesion (2, 3, 19). In this study, we demonstrated that rapid binding of A. phagocytophilum to PMN in a shear flow channel results in rapid PMN arrest that correlates with a small calcium flux and an upshift in CD18 affinity. Despite this response to binding A. phagocytophilum, PMN failed to fully ...

Internalization and survival mechanisms of human ehrlichiosis agents ehrlichia chaffeensis and anaplasma phagocytophilum in...Internalization and survival mechanisms of human ehrlichiosis agents ehrlichia chaffeensis and anaplasma phagocytophilum in...
Obligatory intracellular, human ehrlichiosis agents Ehrlichia chaffeensis and Anaplasma phagocytophilum have remarkable abilities to parasitize first-line immune defensive cells, monocytes/macrophages and granulocytes, respectively. As newly discovered pathogens, the bacterial or host components, the signaling pathways required for their internalization and proliferation, and how these bacteria inhibit the microbicidal activities in host cells remain vastly unknown. In this study, we found that the entry of E. chaffeensis into THP-1 cells rapidly induces the following essential signaling events: protein cross-linking by transglutaminase, tyrosine phosphorylation, phospholipase C (PLC)-?2 activation, IP 3 production, and an increase in cytosolic free calcium levels. The entry and proliferation of these pathogens involve caveolae-mediated endocytosis and glycosylphosphatidylinositol-anchored proteins. Furthermore, caveolar marker protein caveolin-1, tyrosine-phosphorylated proteins, and PLC-?2 are ...

Serological surveys have confirmed Anaplasma marginale and Anaplasma phagocytophilum infections in dromedary camels, but molecular surveys and genetic characterisation of camel-associated Anaplasma species are lacking. In this study, we detected tick-borne Anaplasmataceae in 30 of 100 (30%) healthy dromedary camels screened using a combined 16S rRNA-groEL PCR-sequencing approach. Nucleotide sequencing confirmed Anaplasmataceae genome presence in 28 of the 33 16S rRNA PCR-positive samples, with two additional positive samples, for which 16S rRNA sequence data were ambiguous, being identified by groEL gene characterisation. Phylogenetic analyses of a 1289 nt segment of the 16S rRNA gene confirmed the presence of a unique Ehrlichia lineage and a discrete Anaplasma lineage, comprising three variants, occurring at an overall prevalence of 4% and 26%, respectively. Genetic characterisation of an aligned 559 nt groEL gene region revealed the camel-associated Anaplasma and Ehrlichia lineages to be novel ...

Guidelines for the direct detection of Anaplasma spp. In diagnosis and epidemiological studies | The Pirbright InstituteGuidelines for the direct detection of Anaplasma spp. In diagnosis and epidemiological studies | The Pirbright Institute
The genus Anaplasma (Rickettsiales: Anaplasmataceae) comprises obligate intracellular Gram-negative bacteria that are mainly transmitted by ticks, and currently includes six species: Anaplasma bovis, Anaplasma centrale, Anaplasma marginale, Anaplasma phagocytophilum, Anaplasma platys, and Anaplasma ovis. These have long been known as etiological agents of veterinary diseases that affect domestic and wild animals worldwide. A zoonotic role has been recognized for A. phagocytophilum, but other species can also be pathogenic for humans.

Establishing a Protocol for the Long-term Sampling and Analysis of Tick-borne Pathogens in the Lehigh Valley Rachel Heist1 1Department of Infectious Diseases, Lehigh Valley Health Network Abstract The blackedlegged tick, Ixodes scapularis, transmits several human pathogens including the spirochete that causes Lyme disease (Borellia burgdorferi), which is endemic to the Lehigh Valley region of eastern Pennsylvania. Additional tick-borne diseases have also been emerging in the region including tick-borne relapsing fever (caused by Borrelia miyamotoi), human granulocytic anaplasmosis (caused by Anaplasma phagocytophilum), and human babesiosis (caused by Babesia microti). The dog tick, Dermacentor variabilis, is capable of transmitting Rocky Mountain Spotted Fever (caused by Rickettsia rickettsii). To determine the entomological risk of infection by a tick-borne pathogen, a protocol was established to gather data for a long-term study. Eleven collection sites were screened and selected for analysis

Anaplasmosis, 2012: DCN - Minnesota Dept. of HealthAnaplasmosis, 2012: DCN - Minnesota Dept. of Health
Human anaplasmosis (formerly known as human granulocytic ehrlichiosis) is caused by Anaplasma phagocytophilum, a rickettsial organism transmitted to humans by bites from Ixodes scapularis (the blacklegged tick or deer tick). In Minnesota, the same tick vector also transmits the etiologic agents of Lyme disease, babesiosis, one form of human ehrlichiosis, and a strain of Powassan virus. A. phagocytophilum can also be transmitted by blood transfusion. In 2012, 507 confirmed or probable anaplasmosis cases (9.5 cases per 100,000 population) were reported (Figure 1). The median number of 317 cases (range, 139 to 782 cases) reported from 2004 through 2012 is also considerably higher than the median number of cases reported annually from 1996 to 2003 (median, 56 cases; range, 14 to 149). Three hundred eleven (61%) cases reported in 2012 were male. The median age of cases was 56 years (range, 1 to 99 years), 17 years older that are endemic to other tick-borne diseases transmitted by I. scapularis. POW ...

Anaplasma species infection mimics many other conditions, including other chronic infections. If you are experiencing hard-to-diagnose chronic symptoms and have had a recent tick attachment or live in a region endemic for Anaplasma species in ticks, you should consider testing for Anaplasma infection. Symptoms can range from mild to serious illness characterized by fever, chills, headache, confusion, myalgia, nausea/vomiting/diarrhea, acute weight loss, abdominal pain, difficulty breathing, neurological problems and other conditions that may require immediate medical attention. This zoonotic infection is primarily transmitted to humans by Ixodes ticks, but can also be transmitted through blood transfusion. Clinical presentations may be more severe when co-infected with multiple tick-borne pathogens.. Tests Offered. Anaplasma species PCR test is designed to detect all pathogenic Anaplasma species. Positive results are confirmed by DNA sequencing to identify the infecting species. It is ...

A multiplex serologic platform for diagnosis of tick-borne diseases | Scientific ReportsA multiplex serologic platform for diagnosis of tick-borne diseases | Scientific Reports
Tick-borne diseases are the most common vector-borne diseases in the United States, with serology being the primary method of diagnosis. We developed the first multiplex, array-based assay for serodiagnosis of tick-borne diseases called the TBD-Serochip. The TBD-Serochip was designed to discriminate antibody responses to 8 major tick-borne pathogens present in the United States, including Anaplasma phagocytophilum, Babesia microti, Borrelia burgdorferi, Borrelia miyamotoi, Ehrlichia chaffeensis, Rickettsia rickettsii, Heartland virus and Powassan virus. Each assay contains approximately 170,000 12-mer linear peptides that tile along the protein sequence of the major antigens from each agent with 11 amino acid overlap. This permits accurate identification of a wide range of specific immunodominant IgG and IgM epitopes that can then be used to enhance diagnostic accuracy and integrate differential diagnosis into a single assay. To test the performance of the TBD-Serochip, we examined sera from patients

Leprosy Mailing List Blog: Human Anaplasmosis and Leprosy. A case reportLeprosy Mailing List Blog: Human Anaplasmosis and Leprosy. A case report
Anaplasmosis: on an epidemiological point of view, it was not immediately clear if our patient had been exposed to tick infested in rural areas or had been in contact with pets or wild animals. Nevertheless, his stay in town parks and night cohabitation with homeless people could well have exposed him to ticks. The absence of acute phase reactants in a highly febrile patient was another intriguing point. Actually, Anaplasma phagocytophylum has as virulence factor the escape from neutrophil phagocytosis, through the inhibition of phagolysosome fusion. Although it is a potent inducer of -- INF, at the same time it behaves as an inhibitor suppressing the expression of -- INF membrane receptors and inhibiting the proinflammatory action in favour of bacterial multiplication withi n neutrophils (5- 6). The apparent failure of the appropriate treatment for anaplasmosis was another point of doubt since, despite the abatement of fever, the clinical course tended toward a greater severity. Limited ...
