Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.DNA, Bacterial: Deoxyribonucleic acid that makes up the genetic material of bacteria.Borrelia burgdorferi: A specific species of bacteria, part of the BORRELIA BURGDORFERI GROUP, whose common name is Lyme disease spirochete.Horses: Large, hoofed mammals of the family EQUIDAE.

The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

Emergence of Anaplasma marginale antigenic variants during persistent rickettsemia. (1/194)

Anaplasma marginale is an ehrlichial pathogen of cattle, in the order Rickettsiales, that establishes persistent cyclic rickettsemia in the infected host. Within each rickettsemic cycle, A. marginale expressing antigenically variant major surface protein 2 (MSP2) emerge. By cloning 17 full-length msp2 transcripts expressed during cyclic rickettsemia, we determined that emergent variants have a single, central hypervariable region encoding variant B-cell epitopes. The N- and C-terminal regions are highly conserved among the expressed A. marginale variants, and similar sequences define the MSP2 homologues in the agent of human granulocytic ehrlichiosis (HGE). This is in contrast to the MSP2 homologues in ehrlichial genogroup I pathogens, Ehrlichia chaffeensis, Ehrlichia canis, and Cowdria ruminantium, that have multiple hypervariable regions. By defining the variable and conserved regions, we were able to show that the single hypervariable region of A. marginale MSP2 encodes epitopes that are immunogenic and induce variant-specific antibody responses during persistent infection. These findings demonstrate that the MSP2 structural variants that emerge during each cycle of persistent rickettsemia are true antigenic variants, consistent with MSP2 antigenic variation as a mechanism of A. marginale persistence.  (+info)

Strain composition of the ehrlichia Anaplasma marginale within persistently infected cattle, a mammalian reservoir for tick transmission. (2/194)

Tick-borne ehrlichial pathogens of animals and humans require a mammalian reservoir of infection from which ticks acquire the organism for subsequent transmission. In the present study, we examined the strain structure of Anaplasma marginale, a genogroup II ehrlichial pathogen, in both an acute outbreak and in persistently infected cattle that serve as a reservoir for tick transmission. Using the msp1alpha genotype as a stable strain marker, only a single genotype was detected in a disease outbreak in a previously uninfected herd. In contrast, a diverse set of genotypes was detected in a persistently infected reservoir herd within a region where A. marginale is endemic. Genotypic diversity did not appear to be rapidly generated within an individual animal, because only a single genotype, identical to that of the inoculating strain, was detected at time points up to 2 years after experimental infection, and only a single identical genotype was found in repeat sampling of individual naturally infected cattle. Similarly, only a single genotype, identical to that of the experimentally inoculated St. Maries or South Idaho strain, was identified in the bloodmeal taken by Dermacentor andersoni ticks, in the midgut and salivary glands of the infected ticks, and in the blood of acutely infected cattle following tick transmission. The results show that mammalian reservoirs harbor genetically heterogeneous A. marginale and suggest that different genotypes are maintained by transmission within the reservoir population.  (+info)

Sensitivity and specificity of the complement fixation test for detection of cattle persistently infected with Anaplasma marginale. (3/194)

The complement fixation (CF) test commonly is used to identify cattle infected with Anaplasma marginale prior to interstate or international movement. Estimates of the accuracy of the CF test in detecting animals persistently infected with A. marginale vary widely. In this study, the sensitivity and specificity of the CF test for detection of carrier animals was determined using serum from 232 cattle previously defined as A. marginale positive or negative by nested polymerase chain reaction methods and hybridization. Considering results from 2 independent laboratories and interpreting a 1:5 suspect reaction as positive, the best estimate of CF test sensitivity was 20%, with a specificity of 98%. Using a 1:10 cutoff, sensitivity decreased to 14% and specificity increased to 99%. Results of this study indicate that the CF test is ineffective for identifying cattle persistently infected with A. marginale and thus is inadequate for anaplasmosis regulatory and surveillance programs.  (+info)

Selective in vivo depletion of CD4(+) T lymphocytes with anti-CD4 monoclonal antibody during acute infection of calves with Anaplasma marginale. (4/194)

To investigate the in vivo role of CD4(+) T lymphocytes during acute anaplasmosis, thymectomized calves were selectively depleted of CD4(+) T lymphocytes by treatment with anti-CD4 monoclonal antibody (MAb) and were then infected with the Florida strain of Anaplasma marginale in two sequential experiments (experiments 1 and 2). Treatment of thymectomized calves with a total of 5.0 mg of anti-CD4 MAb/kg of body weight during the 1st week followed by 0.3-mg/kg doses administered twice weekly for 7 weeks resulted in significant depletion of CD3(+) CD4(+) and CD4(+) CD45R(+) (naive) T lymphocytes from blood, spleen, and peripheral lymph nodes for the duration of the 8-week study, compared to the results for thymectomized control calves treated with a subclass-matched MAb. All calves became parasitemic and pyretic following experimental infection with A. marginale, and decreases in packed cell volume (PCV) coincided with peak parasitemia. No significant differences in PCV or parasitemia were observed between treatment groups. Thymectomized calves treated with anti-CD4 MAb were able to mount an anti-A. marginale antibody response, although in experiment 2, anti-CD4 MAb-treated calves had four- to sixfold lower immunoglobulin G1 (IgG1) and no detectable IgG2 anti-A. marginale major surface protein 2-specific antibody titers compared to thymectomized control calves treated with a subclass-matched MAb. At the level of CD4(+)-T-lymphocyte depletion achieved and experimental anaplasmosis induced, thymectomized anti-CD4 MAb-treated calves were able to control acute anaplasmosis. This was in contrast to the prediction that significant depletion of CD4(+) T lymphocytes would abrogate resistance to acute infection.  (+info)

Seroprevalence of antibodies that react with Anaplasma phagocytophila, the agent of human granulocytic ehrlichiosis, in different populations in Westchester County, New York. (5/194)

We determined the frequencies of antibodies to Anaplasma phagocytophila, the agent of human granulocytic ehrlichiosis (HGE), in different groups of adults and children from Westchester County, New York. The groups included 159 adult blood donors and 215 children who were seronegative for Borrelia burgdorferi antibodies, 118 adult patients and 57 children who were seropositive for B. burgdorferi antibodies, and 42 adult patients with culture-confirmed erythema migrans. Eighteen (11.3%) of the blood donors and 11 (5.1%) of the B. burgdorferi-seronegative children were found to have A. phagocytophila antibodies by indirect immunofluorescent-antibody assay (IFA). Nine of 42 (21.4%) patients with culture-confirmed erythema migrans tested at the baseline visit, 42 of 118 (35.6%) adults, and 3 of 57 (5.3%) children whose sera were reactive for B. burgdorferi antibodies also tested positive for A. phagocytophila antibodies. The geometric mean titer ranged from 219 to 315 for all groups, and the differences in titers among the groups were not statistically significant. Only one-third of the healthy blood donors reactive by IFA were confirmed to be positive by immunoblotting. We conclude that a significant proportion of adults and children without clinical evidence of HGE will test positive for A. phagocytophila antibodies when the conventional cutoff titer of 80 is used in the IFA. This information must be considered in interpretation of test results.  (+info)

Superoxide anion production during Anaplasma phagocytophila infection. (6/194)

Anaplasma phagocytophila persists within neutrophils and prevents the respiratory burst by inhibiting gp91(phox). Mutations in gp91(phox) result in chronic granulomatous disease (CGD), which is diagnosed by use of the nitroblue tetrazolium (NBT) and Fc-Oxyburst assays that examine whether cells produce O2-. This study assessed whether the NBT and Fc-Oxyburst assays could detect a respiratory burst during A. phagocytophila infection. O2- production was inhibited in HL-60 cells and neutrophils infected with A. phagocytophila. In a mouse model of A. phagocytophila infection, 15%+/-4% (mean+/-SD) of polymorphonuclear leukocytes from infected mice had an ineffective respiratory burst compared with 1%+/-1% (mean+/-SD) of the neutrophils from uninfected animals. A population of neutrophils that did not produce O2- was also detected in 2 patients with A. phagocytophila infection. These data demonstrate respiratory burst inhibition by A. phagocytophila in vivo and on an individual cell basis by use of assays designed to evaluate CGD.  (+info)

Analysis of sequences and loci of p44 homologs expressed by Anaplasma phagocytophila in acutely infected patients. (7/194)

Anaplasma phagocytophila is an obligatory intragranulocytic bacterium that causes human granulocytic ehrlichiosis. Immunodominant 44-kDa outer membrane proteins of A. phagocytophila are encoded by a p44 multigene family. In the present study, expression profiles of p44 genes in the blood of acutely infected patients in the year 2000 were characterized. A single p44 gene was predominantly expressed in peripheral blood leukocytes from one patient, while up to 17 different p44 genes were transcribed without a single majority in the other two patients. The cDNA sequences of the central hypervariable region of several p44 genes were identical among the isolates from the three patients and a 1995 A. phagocytophila isolate. A. phagocytophila was isolated by cell culture from all of the three 2000 patients. Genomic Southern blot analysis of the three 2000 and two 1995 A. phagocytophila isolates with probes specific to the most dominant p44 transcript in each patient showed that the p44 loci in the A. phagocytophila genome were conserved. Analysis of the predicted amino acid sequences of 43 different p44 genes including 19 new sequences found in the present study, revealed that five amino acids were absolutely conserved. The hypervariable region was subdivided into five domains, including three extremely hypervariable central domains. These results suggest that variations in the sequences of p44 are not random but are restricted. Furthermore, several p44 genes are not hypermutatable in nature, based on the conservation of gene sequences and loci among isolates obtained 5 years apart.  (+info)

Serologic and molecular detection of Ehrlichia chaffeensis and Anaplasma phagocytophila (human granulocytic ehrlichiosis agent) in Korean patients. (8/194)

Sera from 491 Korean patients with acute febrile diseases were tested for Ehrlichia chaffeensis and Anaplasma phagocytophila antibodies by indirect immunofluorescence assay (IFA), Western blotting, and TaqMan real-time PCR. Overall, 0.4% of sera reacted with E. chaffeensis, and 1.8% reacted with A. phagocytophila in IFAs. This is the first report of detection of antibodies to A. phagocytophila and E. chaffeensis in Korea and suggests the presence of A. phagocytophila and E. chaffeensis or antigenically similar species.  (+info)

Effects of adding phenol to sera used for the card-agglutination test (CAT) and for the micro-complement-fixation test (CFT) for bovine anaplasmosis were studied. Sera were obtained from 14 recently infected cattle, 17 cattle vaccinated with a killed anaplasmosis vaccine, 5 cattle in the carrier phase of the disease, and 45 cattle of unknown anaplasmosis status. Aliquots of sera were tested with and without phenol (0.25% final concentration). Phenol adversely affected the CAT by causing false-negative results. The CAT reactions of nonphenolized sera from recently infected cattle were all positive 4 weeks after inoculation, whereas CAT reactions of phenolized sera were not all positive until 10 weeks after inoculation. Nine non-phenolized sera from vaccinated cattle that were CAT-positive were CAT-negative after being phenolized. Phenolized sera from carrier cattle and from cattle of unknown anaplasmosis status were less reactive on the CAT than were nonphenolized sera. Effects of phenol on the CFT were
Anaplasmosis is a tick-borne transmitted infection. Its clinical expression include fever, cytopenia and hepatitis.This infection was initially described in United States. In Europe, its epidemiology is not well known. Some isolated cases have been diagnosed in several country, were the tick Ixodes ricinus is known to transmitted another infection :the Lyme borreliosis.The purpose of our study is to look systematically for Anaplasmosis, in patient living in Eastern France, and presenting with compatible clinical symptoms using a new diagnosis tool : PCR in blood samples. So we will have new data about epidemiology in our country and the clinical symptoms that are associated with Anaplasmosis ...
Introduction. Bovine anaplasmosis is caused by the intraerythrocytic rickettsia Anaplasma marginale and is an endemic condition in tropical and subtropical areas. Ticks are the biological vector, but transmission may also occur mechanically by mosquitoes and bloodsucking flies (YERUHAM; BRAVERMAN, 1981). In endemic areas, calves are infected during the first months of life. Acute infections develop into a clinical disease characterized by anemia and weight loss (CORRIER; GUZMAN, 1977; RIBEIRO; REIS, 1981), and death can occur in 36% (PALMER, 1989). Animals that survive the clinical disease remain persistent carriers with low rickettsemia. They may be a source of infection for other susceptible animals that become infected through mechanical and biological vectors (SCHILF, 1971). Animal susceptibility increases with age, and younger animals are more resistant to the first infection, and have less severe clinical symptoms (ROBY et al., 1961; JONES et al., 1968).. Over the past 30 years no new ...

Aim: Anaplasma marginale is a rickettsial pathogen responsible for progressive anemia in ruminants leading to huge economic losses. The objectives of this cross-sectional study were to determine the prevalence of anaplasmosis and therapeutic evaluation of traditional line of treatment.. Materials and Methods: A total of 168 cattle presented to Teaching Veterinary Clinical Complex, Lala Lajpat Rai University of Veterinary & Animal Sciences, Hisar during the period of 3 months (July-September, 2014) with history of fever, anorexia, reduced milk yield and tick infestation were analyzed for prevalence of hemoprotozoan diseases using classical giemsa stained thin blood smear parasitological method.. Results: Out of these 168 animals, 7 (4.17%) were found to be suffering from anaplasmosis on the basis of presence of dense, rounded, intra-erythrocytic bodies situated on or near the margin of the erythrocytes. Overall prevalence of theileriosis and babesiosis were found to be 42.9% and 1.8%, ...
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 ...
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 ...
Typically, cases of anaplasmosis increase in late summer and fall as insect vectors increase. Therefore, control of vectors is key to preventing anaplasmosis.

Actually, these days a diagnosis is straightforward. Do you have some or all of that litany of symptoms, especially fever and fatigue? Were you in any place a week or two ago where there might have been ticks? Do you have any symptoms which hint you may have something else? If not the last, thats it. A blood sample will be taken, but early in the course of the infection the test results can be falsely negative (results say you dont, but you do). Standard medical practice is to start antibiotic treatment immediately. Treatment should never be delayed until the lab results are back. Standard treatment is the same as for Lyme - two weeks of doxycycline ...

Different markets are sending varying signals about the health of the global economy. Investors should not take unnecessary risks, but we still see select opportunities.
Anaplasmosis is transmitted by the black-legged tick, which is the same tick that spreads Lyme disease, and the most common tick found in Vermont. As of September, 133 cases of anaplasmosis have been reported, only six fewer than were reported for all of 2015.. Although anaplasmosis cases peak in the spring and summer, a second surge in illnesses occurs in the autumn. That is when adult ticks are hungry and looking for another blood meal before winter arrives.. "Anaplasmosis is a serious illness, and were seeing more of it in Vermont," said Bradley Tompkins, infectious disease epidemiologist. According to Tompkins, over one-third of the anaplasmosis cases reported to the Health Department are sick enough to be hospitalized, compared to 3 percent for Lyme disease. Symptoms can include fever, headache, chills and muscle aches. Anaplasmosis can be successfully treated with antibiotics, especially if treatment is given early.. Tompkins urges people to not drop their guard just because summer is ...
We retrospectively confirmed 2 cases of human Anaplasma phagocytophilum infection. Patient blood samples contained unique p44/msp2 for the pathogen, and antibodies bound to A. phagocytophilum antigens propagated in THP-1 rather than HL60 cells. Unless both cell lines are used for serodiagnosis of rickettsiosis-like infections, cases of human granulocytic anaplasmosis could go undetected.
A 36-year-old woman acquired severe human granulocytic anaplasmosis after blood transfusion following a cesarean section. Although intensive treatment with mechanical ventilation was needed, the patient had an excellent recovery. Disease caused by Anaplasma phagocytophilum infection was confirmed in 1 blood donor and in the transfusion recipient.

INTRODUCTION Anaplasmosis in cattle is an arthropod-borne disease caused predominantly by the intraerythrocytic rickettsia Ana-plasma marginale21. Anaplasmosis is characterised by mucosal pallor, depression, inappetance, general weakness and a rapidly rising parasitaemia21. Pyrexia is an inconsistent finding21. The severity of clinical disease is directly related to the age of the animal: in animals less than 1 year old it is usually subclinical, in yearlings and 2-year-olds it is moderately severe while in older cattle it is severe and often fatal9. Vertical transmission of anaplasmosis has been documented, although its significance in the spread of the diseases is unclear13,27,28,31. Experiments attempting to demonstrate vertical transmission where progeny from known Anaplasma carrier cows were utilised, as well as where cows were acutely infected with Anaplasma during gestation, did not produce clinically ill progeny13,27,31. In utero transmission has either been demonstrated by inoculating ...
This workshop proceeding discusses the importance of anaplasmosis, babesiosis and cowdriosis; the methods of control being used for the diseases and the problems encountered with these control methods; recent findings in the epidemiology and molecular biology of these diseases, and developments towards new vaccines. Topics of discussion include distribution, economic importance, control measures, diagnosis, approaches to new vaccines, and in vitro cultivation. Under the topic diagnosis, papers are presented on development of diagnostic reagents for anaplasmosis and babesiosis; serodiagnosis of Cowdria ruminantium, and DNA probes for this species. The papers under approaches to new vaccines examine molecular biology of rickettsiae with particular reference to gene organization and structure in Anaplasma marginale and Cowdria ruminantium; methodological approaches to the study of resistance in cowdriosis and the possible role of cell-mediated immunity; progress in development of subunit vaccines ...
Anaplasmosis in cattle is an infectious disease caused by a bacteria known as Anaplasma marginale. The disease is common in Missouri. Clinical cases can occur at any time of the year, but the majority of cases are seen in late summer and fall. The economic impact of the disease to the state is unknown, but nationwide it is estimated to exceed $300 million a year.1 Economic losses are due to reduced production, treatment costs, death loss and abortion.. Anaplasma marginale causes disease by infecting red blood cells. The immune systems recognizes the infected cells as abnormal and removes them, thereby creating anemia. The severity of disease is related to the number of infected red blood cells and subsequent red blood cell loss. In mild cases, animals may exhibit symptoms such as elevated temperature, depression and pale mucous membranes. In severe cases, animals may be jaundiced, the most obvious symptom of which is a yellow tinge to the mucous membranes around the eyes; exhibit severe ...

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.

Anaplasma spp. are widely spread rickettsial bacteria transmitted by ticks and placing high impacts on veterinary and public health. A limited number of studies have been carried out on Anaplasmosis in the central part of Iraq. This study was conducted to determine the presence of Anaplasma spp. in cattle in Al-Qadisiyah province, Iraq. A total of 400 blood specimens were collected from cattle suffering from heavy tick infestation. Cattle were blood-sampled from four hyper-endemic areas with ticks. Blood samples were screened using microscopic and polymerase chain reaction (PCR) methods. Diff-quick stained blood smears revealed Anaplasma-like inclusion bodies in 254 (63.5%) samples. According to the 16S rRNA-gene-based PCR analysis, Anaplasma spp. was detected in 124 of the 400 (31%) samples, divided as 96/254 (37.8%) among the microscopical positive samples and 28/146 (19.17%) among the microscopical negative samples. Phylogenetic analysis based on the partial 16S rRNA gene sequencing of ...

Vector-Borne and Zoonotic Diseases. 9:431-437. Interpretive Summary: Blacklegged ticks (deer ticks) are the principal vectors of the pathogen causing Lyme disease and also transmit human granulocytic anaplasmosis (ehrlichiosis). Most cases of Lyme disease in humans are due to being bitten by infected blacklegged tick nymphs. The efficacy of 4-poster deer self-treatment devices, developed by researchers at the USDA, ARS Knipling-Bushland U. S. Livestock Insects Research Laboratory , Kerrville, TX, was tested in field trials at locations in five states. Host-seeking blacklegged ticks collected from treatment and control sites annually were tested for the presence of Borrelia ...
If you develop signs or symptoms of a tick-related illness after spending time in areas where deer ticks are found, you should seek medical attention right away.. Not all deer ticks carry the organisms that cause Lyme disease, human anaplasmosis, or babesiosis. If an infected deer tick bites you, it needs to be attached at least 12-24 hours to transmit the human anaplasmosis bacteria and 24-48 hours to transmit the Lyme disease bacteria. Not every person who is infected with these organisms will develop symptoms.. ...
Anaplasma marginale is an important vector-borne rickettsia of ruminants in tropical and subtropical regions of the world. Immunization with purified outer membranes of this organism induces protection against acute anaplasmosis. Previous studies, with proteomic and genomic approach identified 21 proteins within the outer membrane immunogen in addition to previously characterized major surface protein1a-5 (MSP1a-5). Among the newly described proteins were VirB9, VirB10, and elongation factor-Tu (EF-Tu). VirB9, VirB10 are considered part of the type IV secretion system (TFSS), which mediates secretion or cell-to-cell transfer of macromolecules, proteins, or DNA-protein complexes in Gram-negative bacteria. EF-Tu can be located in the bacterial surface, mediating bacterial attachment to host cells, or in the bacterial cytoplasm for protein synthesis. However, the roles of VirB9, VirB10, and TFSS in A. marginale have not been defined. VirB9, VirB10, and EF-Tu have not been explored as vaccine ...
REGION - Ticks: tiny arachnids that depend on the blood of hosts to survive. Their M.O. is to attach to their host and then gorge on its blood. As they do this, they can pass along a variety of diseases. Some of which are deadly, all are unpleasant.. Between 2013 and 2018, confirmed and probable cases of Lyme reported to Maine Center for Disease Control and Prevention increased from 1384 to 1404, or 1.42%. The number of confirmed cases peaked in 2017 at 1,855.. Babesiosis increased from 36 in 2013 to 101 in 2018, or 64%. The most alarming increase is with reports of Anaplasmosis, which rose from 94 cases in 2013 to 476 cases in 2018, an increase of 406%.. According to Maine CDC Tracking Network, there have been 284 cases of Lyme Disease, 402 cases of Anaplasmosis, and 54 cases of Babesiosis reported statewide between Jan. 1 and Aug. 1.. On Wednesday, July 24, Maine CDC announced in a press release a case of Powassan virus infection, a potentially deadly tick-borne illness, had been confirmed in ...

Moms eyes opened, she smiled and reached down to pet me. I feel better already. Mom texted Adri and Alma, she says they are wise dog ladies. Whatever she read on the screen, her eyes half closed and her head nodded. She looked up as the doctor entered with a piece of paper in her hand, the estimate. People wonder what makes them different from us, money could be the answer. I jumped on the bench to sit next to mom. She took her glasses out to read the paper. I felt her flinch.

Took Prairie to the vet this morning and he tested positive for Lyme Disease and Anaplasmosis. I dont know much about Lymes and absolutely nothing about the Anaplasmosis. I have some reading to do. He started him on antibiotics while we wait for the panel to come back on the blood draw that tells us how severe it is. Its his guess that he was infected last summer, so its early, because he otherwise seems to be in good health. And just now I realized I forgot to bring home a kit for a stool sample, so will have to get that soon. I have noticed that Prairie sometimes moans when he lays down. Vet thinks that could be arthritis soreness which would be part of the Lymes. He asked where he came from and I said Danbury, Wisconsin, he said that is a real hotbed for Lymes ...

Classification of bacteria is challenging due to the lack of a theory-based framework. In addition, the adaptation of bacteria to ecological niches often results in selection of strains with diverse virulence, pathogenicity and transmission characteristics. Bacterial strain diversity presents challenges for taxonomic classification, which in turn impacts the ability to develop accurate diagnostics and effective vaccines. Over the past decade, the worldwide diversity of Anaplasma marginale, an economically important tick-borne pathogen of cattle, has become apparent. The extent of A. marginale strain diversity, formerly underappreciated, has contributed to the challenges of classification which, in turn, likely impacts the design and development of improved vaccines. Notably, the A. marginale surface protein 1a (MSP1a) is a model molecule for these studies because it serves as a marker for strain identity, is both an adhesin necessary for infection of cells and an immuno-reactive protein and is ...
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. ER lumen markers, calreticulin and protein disulfide isomerase, and the ER
In situ hybridization (ISH), which allows localization of pathogen nucleic acid in tissue sections, was used to detect A. marginale, a rickettsial pathogen of cattle, in its tick vector. Dermacentor andersoni males were experimentally infected with A. marginale, and one-half of each of 20 ticks was embedded in paraffin or LR White for ISH: companion halves were embedded in DER resin for light microscopy. Sections were digested with proteinase K and hybridized with a digoxigenin-labelled DNA probe. In both paraffin and LR White embedded sections, dark-blue colour precipitates of hybridization signals were visualized in both salivary gland and gut cells. Anaplasma infections were also confirmed by light microscopy in companion tick halves. Positive hybridization signals and A. marginale colonies were not seen in uninfected control tissues. Although ISH detected A. marginale in both paraffin and LR White embedded sections, LR White was found to be optimum for ISH of A. marginale because of improved ...
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 ...
Heparinized whole blood, heavily parasitized with Anaplasma marginale, was collected from 3 splenectomized oxen. Buffered lactose peptone (BLP) was added in equal volumes as a stabilizer and the mixture lyophilized in 2 ml aliquots after rapid freezing. The dried material was reconstituted with 2 ml sterile water and inoculated without delay. The product remained infective for at least 6 months when stored in an ordinary household deep-freeze unit ...
The abundance of cattle is the primary influence on the prevalence of two tick-borne pathogens, according to a paper in the April Applied and Environmental Microbiology. One of these, Anaplasma phagocytophilum, causes human granulocytic anaplasmosis, and the other, Borrelia burgdorferi, causes Lyme disease.
The tickborne diseases have similar symptoms, including fever, headache, fatigue, aches, chills and swelling. If caught early, the diseases can be treated with antibiotics.. Anaplasmosis symptoms are generally more severe than Lyme. About 25 to 30 percent of all anaplasmosis cases result in hospitalization, compared to about 5 percent of Lyme cases. Scientists say an increasing number of deer ticks are infected with anaplasmosis.. Meanwhile, Lyme cases are significantly below recent years, with 684 cases reported through Oct. 1 and the total expected to exceed 1,000 by the end of the year. Thats tracking well below the 1,405 cases in 2018 and the record 1,855 cases in 2017. Since 2013, Maine has ended each year with more than 1,200 Lyme cases. About 15 years ago, Lyme cases were in the low hundreds.. Lyme researchers told the Press Herald this summer that ticks were abundant, and they also cautioned that Lyme statistics reported to the Maine CDC may be lagging, because of potential late ...
The prevalence and incidences of tick-borne diseases (TBDs) infections in cattle were studied in the western-Kenya highlands. Serological tests, thick-blood and lymph-node smears were used to quantify TBDs during cross-sectional and longitudinal studies. Four hundred and eight and 192 (wet season) and 114 and 46 (dry season) cattle were bled for serology in the rural and peri-urban areas, respectively. Seroprevalences differed significantly between the two areas (p , 0.05). The cattle were monitored for 23 months (259,923 and 126,273 cattle days in the rural and peri-urban areas, respectively) from September 1996 to August 1998. The incidences of babesiosis, anaplasmosis and theileriosis were 0.42%, 4.64% and 4.92% and 1.45%, 32.11% and 39.05% in the rural and peri-urban areas, respectively.

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.

In the eastern United States, A. phagocytophilum is transmitted to hosts through the bite of the blacklegged tick, Ixodes scapularis. We determined the realized reservoir competence of 14 species of common vertebrate hosts for ticks by establishing the probability that each species transmits two important strains of A. phagocytophilum (A. phagocytophilum human-Active, which causes human cases, and A. phagocytophilum variant 1, which does not) to feeding larval ticks. We also sampled ...
Anaplasma marginale is the most prevalent tick-borne pathogen of cattle. It is transmitted by ixodid ticks. Symptoms of acute disease are anemia, weight loss, and often death. A.marginale establishes life-long persistent infection in animals that survive disease. These animals are clinically healthy but serve as reservoirs for transmission of the pathogen. Anaplasma marginale subsp. centrale (Anaplasma centrale (strain Israel)) is a naturally occurring attenuated strain has been used as a live vaccine to prevent severe disease due to A. marginale senso stricto strains for 100 years. A. marginale subsp. centrale contains 10 putative genes not found in the genomes of senso stricto strains, while 18 genes found in senso stricto strains are absent from A. marginale subsp. centrale. As inoculation with purified outer membrane protein (OMP) complexes provides immunity against A. marginale, it is important to identify OMPs that differ among A,marginale to identify further vaccine candidates. ...
Shared and unique antigens were identified and partially characterized for two morphologically and antigenically distinct isolates of Anaplasma, A. marginale (Florida) (FAM) and A. caudatum (Illinois) (IAC). Crude CA-like antigens were prepared from the parasitemic blood of each calf, separated by SDS-PAGE, electroblotted onto nitrocellulose, and detected using immune bovine sera and an avidin-biotin-peroxidase assay with biotinylated rabbit anti-goat IgG (cross-reacted with cattle, sheep and deer antibodies). IAC antigens were 200 kilodalton (kd), 100 kd, 96 kd, 75 kd, 47 kd, 43 to 38 kd, and 27 kd, detected using anti-IAC and anti-FAM sera.

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.

Ubiquinone (UQ), also called coenzyme Q, and plastoquinone (PQ) are electron carriers in oxidative phosphorylation and photosynthesis, respectively. The quinoid nucleus of ubiquinone is derived from the shikimate pathway; 4-hydroxybenzoate is directly formed from chorismate in bacteria, while it can be formed from either chorismate or tyrosine in yeast. The following biosynthesis of terpenoid moiety involves reactions of prenylation, decarboxylation, and three hydroxylations alternating with three methylations. The order of these reactions are somewhat different between bacteria and yeast. Phylloquinone (vitamin K1), menaquinone (vitamin K2), and tocopherol (vitamin E) are fat-soluble vitamins. Phylloquinone is a compound present in all photosynthetic plants serving as a cofactor for photosystem I-mediated electron transport. Menaquinone is an obligatory component of the electron-transfer pathway in bacteria ...
Ticks are second only to mosquitoes throughout the world in transmitting infectious disease to humans and animals.. Although the majority of tick-borne diseases in dogs and cats are thought to be exotic to the UK, Lyme disease and Anaplasmosis are already present in the UK, both having the potential to infect not only pets but humans as well.. LYME DISEASE is a bacterial infection that is usually carried by the deer tick. Symptoms include lameness, fever, loss of appetite, fatigue and an abnormal enlargement of the lymph nodes. It is often treatable with antibiotics.. ANAPLASMOSIS is an infectious blood disease that attacks the white blood cells, crippling the immune system. Symptoms include fever, depression, seizures, meningitis, lameness and joint swelling, weight loss, and loss of appetite. It is treatable with antibiotics.. Tick-borne disease is an emerging illness that is often misdiagnosed due to the variety of symptoms, all of which can mimic other conditions. Whilst these symptoms are ...
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.
BACKGROUND: Only a few studies have examined the presence of Anaplasma marginale and Anaplasma centrale in South Africa, and no studies have comprehensively examined these species across the whole country. To undertake this country-wide study we adapted a duplex quantitative real-time PCR (qPCR) assay for use in South Africa but found that one of the genes on which the assay was based was variable ...

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 ...

A vast number of novel tick-related microorganisms and tick-borne disease agents have been identified in the past 20 years, and more are being described due to several factors, from the curiosity of clinicians faced with unusual clinical syndromes to new tools used by microbiologists and entomologists. Borrelioses, ehrlichioses, anaplasmosis, and tick-borne rickettsial diseases are some of the emerging diseases that have been described throughout the world in recent years. In this article, we focus on the bacterial agents and diseases that have been recognized in the past 3 years and refer to major recent reviews of other recognized infections.

If we really want to get more women into STEM fields, we need to enact a moratorium on Marie Curie. Its all well and good to have that obligatory female nerd in the lab on every procedural mystery TV show, to include some lab-coated ladies in a Lego set, or to add a computer engineer Barbie to Mattels latest line (though that one didnt go so well). But clearly its not enough. Every single one of us needs to scrub that you-know-who reflex from our brain and replace it with a diverse set of important female innovators. When we do, girls will gain Grace Hopper, who was one of the most important-and colorful-computer scientists in history; Marie Tharp, who mapped the ocean floor and saw evidence of continental drift years before her partner or others in the scientific community accepted the idea; Virginia Apgar, whose scoring system for newborns has saved countless babies lives; and Inge Lehmann, who discovered Earths inner core. ...

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 ...
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
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.
This 2005 image depicted a male "brown dog tick", Rhipicephalus sanguineus from a superior, or dorsal view looking down on this "hard ticks" scutum, or keratinized "shield" which entirely covers its back, identifying it as a male. In the female, the dorsal abdomen is only partially covered, thereby, offering room for abdominal expansion when she becomes engorged with blood while ingesting her blood meal obtained from her host.. Though not the primary vector for Rocky Mountain spotted fever (RMSF) like the "American dog tick", Dermacentor variabilis, and the "Rocky Mountain wood tick" D. andersoni, R. sanguineus has been found to be a less-common vector as well. This tick is distributed throughout the world. It also is known to transmit diseases to animals including canine babesiosis, bovine anaplasmosis, East Coast fever and Texas cattle fever. It can also spread tularemia, and tick-borne typhus to human beings.. RMSF, like all rickettsial infections, is classified as a zoonosis. Zoonoses are ...
