Gastrointestinal and hepatic manifestations of tickborne diseases in the United States. (1/8)

Signs and symptoms related to the gastrointestinal tract and liver may provide important clues for the diagnosis of various tickborne diseases prevalent in different geographic areas of the United States. We review clinical and laboratory features that may be helpful in detecting a tickborne infection. Physicians evaluating patients who live in or travel to areas where tickborne diseases are endemic and who present with an acute febrile illness and gastrointestinal manifestations should maintain a high index of suspicion for one of these disease entities, particularly if the patient has received a tick bite. If detected early, many of these potentially serious illnesses can be easily and effectively treated, thereby avoiding serious morbidity and even death.  (+info)

Recombinant VP7-based enzyme-linked immunosorbent assay for detection of immunoglobulin G antibodies to Colorado tick fever virus. (2/8)

VP6, VP7, VP9, VP10, VP11, and VP12 of Colorado tick fever virus (CTF virus), a virus member of the genus Coltivirus, family Reoviridae, were expressed in bacteria with the pGEX-4T-2 vector. A partial sequence of VP7 (designated pVP7) was chosen to elaborate an enzyme-linked immunosorbent assay (ELISA) for detecting anti-CTF virus immunoglobulin G (IgG) antibodies in humans. This was based on two observations: (i) among all expressed proteins, pVP7 showed the highest immunoreactivity to an anti-CTF virus hyperimmune ascitic fluid; (ii) to provide the highest selectivity of antibody detection, the expressed sequence was chosen within a region which is highly divergent (49% amino acid identity) from the homologous sequence of another coltivirus, the Eyach virus. The pVP7 ELISA was evaluated with 368 serum samples from French blood donors and found to provide 98.1% specificity. Assays with the Calisher set of human serum samples, positive for anti-CTF virus antibodies (C. H. Calisher, J. D. Poland, S. B. Calisher, and L. A Warmoth, J. Clin. Microbiol. 22:84-88, 1985), showed that the pVP7 ELISA provided 100% sensitivity for the tested population. After elaboration of recombinant-protein-based ELISAs for diagnosis of infections with members of the viral genera Orbivirus, Orthoreovirus, and Rotavirus, it was shown that a recombinant protein could be used to detect antibodies to the human pathogen Colorado tick fever virus.  (+info)

Diagnosis of Colorado tick fever virus infection by enzyme immunoassays for immunoglobulin M and G antibodies. (3/8)

An immunoglobulin M (IgM) capture enzyme immunoassay technique was adapted for the detection of antibody to Colorado tick fever virus in sera from 84 individuals for whom diagnosis had been confirmed by virus isolation or neutralization test. Titers were compared with those for IgG and neutralizing antibodies in these Colorado tick fever cases. IgM antibody titers were higher than neutralizing antibody titers, but neither appeared until 1 to 2 weeks after the onset of illness. Neutralizing antibodies were detected earlier than IgM antibodies, and both were detected with greater frequency than IgG antibodies. Late-convalescent-phase sera contained both neutralizing and IgG antibodies, but IgM was all but undetectable by 2 months after onset. Although the neutralization test may remain the serological test of choice, the enzyme immunoassay for IgM antibody offers a simple and more rapid method of serodiagnosis; the enzyme immunoassay is, however, less sensitive than the neutralization test. Furthermore, because there was a sharp decline in IgM antibody after 45 days, the presence of IgM antibody in a single serum sample provides a basis for the presumptive serodiagnosis of recent Colorado tick fever virus infection.  (+info)

Arbovirus infections in man in British Columbia. (5/8)

During the summer of 1971, the first laboratory-proved cases of acute encephalitis in man due to any of the known arboviruses occurred in the south-central region of British Columbia. Five human cases of encephalitis with two deaths were diagnosed; three of these patients, including one of the fatalities, were proven in the laboratory to have contracted western equine encephalitis.During 1968 and 1969, a human serum survey undertaken in approximately 2000 life-long residents of the province discovered low levels of hemagglutinin-inhibiting and/or complement-fixing as well as neutralizing antibodies for western equine encephalitis, St. Louis encephalitis, Powassan encephalitis, California encephalitis and Colorado tick fever. Evidence of recent sub-clinical infection was detected in some cases.  (+info)

Detection of Colorado tick fever virus by using reverse transcriptase PCR and application of the technique in laboratory diagnosis. (7/8)

Colorado tick fever (CTF) virus elicits an acute illness in humans, producing nonspecific flu-like symptoms and a biphasic fever in approximately 50% of patients. The disease is transmitted by the adult Rocky Mountain wood tick (Dermacentor andersoni), and therefore incidence is limited by the habitat and life cycle of that vector. The early symptoms of infection are difficult to distinguish from those of several other agents, especially Rickettsia rickettsii. Serologic testing is usually unable to provide evidence of CTF viral infection during the acute phase because of the late appearance of the various antibodies. Here we report the development and clinical application of a test to diagnose this disease during the acute stages. Oligonucleotide primers to the S2 segment of CTF (Florio) virus were made, and these were used in the amplification of a 528-bp fragment of DNA, transcribed from the double-stranded CTF virus RNA template by reverse transcriptase PCR. RNAs processed from 16 CTF virus isolates yielded similar results when analyzed on agarose gels. These were distinguishable from their antigenic relatives Eyach, S6-14-03, and T5-2092 and from other coltiviruses and an orbivirus but not from the antigenically distinct CTF virus-related isolate 720896. A mouse model demonstrated the utility of this method with whole-blood specimens, and CTF virus was successfully detected in human sera from the initial day of the onset of symptoms to 8 days later. The reverse transcriptase PCR method is a promising tool for the early diagnosis of CTF viral infection, or for ruling out CTF virus as the etiologic agent, in order to facilitate appropriate medical support.  (+info)

Serologic and molecular diagnosis of Colorado tick fever viral infections. (8/8)

Molecular and serologic methods usable for the biological diagnosis of Coltivirus infection are reported. We designed a multiplex reverse transcription-polymerase chain reaction system that allowed the simultaneous and specific amplification of three genomic segments from as little as 0.01 plaque-forming units. Another system in the S2 viral segment permitted the differential diagnosis of American and European viral isolates. We also discuss some improvements of previous ELISAs, and the results obtained with paired sera from Colorado tick fever (CTF) virus-infected individuals. Western blot analysis was developed that allowed the detection of antibodies to a 38-kD viral protein in all tested sera. It also enabled the detection of anti-CTF virus antibodies in ELISA-negative sera. Specific IgM antibodies against a synthetic viral peptide could be detected in sera at the acute stage of the infection. Together, these results should permit the diagnosis of Coltivirus infection at any stage of the pathology.  (+info)

Colorado tick fever (CTF) (also called mountain tick fever, American tick fever, and American mountain tick fever) is a viral infection (Coltivirus) transmitted from the bite of an infected Rocky Mountain wood tick (Dermacentor andersoni). It should not be confused with the bacterial tick-borne infection, Rocky Mountain spotted fever. The type species of the genus Coltivirus, Colorado tick fever virus (CTFV) infects haemopoietic cells, particularly erythrocytes, which explains how the virus is transmitted by ticks and also accounts for the incidence of transmission by blood transfusion. The disease develops from March to September, with the highest infections occurring in June. The disease is found almost exclusively in the western United States and Canada, mostly in high mountain areas such as Colorado and Idaho. The CTFV was first isolated from human blood in 1944. The virus particle, like other coltiviruses, is about 80 nm in diameter and is generally not enveloped. The double-stranded RNA ...
Colorado tick fever (CTF) is a disease caused by an RNA virus, Colorado tick fever virus (CTFV). Symptoms, which are often non-specific, begin 3 to 5 days after the bite with an abrupt onset of fever and any of these: headaches, chills, malaise, photophobia, myalgias, nausea, vomiting, diarrhea and abdominal pain. In 5 to 15% of cases a rash occurs. Neurologic complications may also occur. 50% of patients have single recurrence of fever ("saddleback" fever).. IFA titers for diagnosis. PCR (Polymerase Chain Reaction) is the test most often used to diagnose the disease. CTF is transmitted by Dermacentor andersoni (Rocky Mt. wood tick) which causes illness from the Western Black Hills to the West Coast in the USA. Some cases of transmission through blood transfusion have been reported. Treatment consists of supportive care.. ©LDA. 2014. 2015.

Abstract Isolation of the virus, the most reliable means of diagnosing Colorado tick fever, is not always practicable. The standard complement-fixation test, using a mouse-brain-derived antigen, may not detect significant rises in antibody titer during the usual 2- or 3-week observation period. Complement-fixation (CF) tests, with antigens derived from infected mouse brains and from an established line of hamster-kidney cells, were compared with a neutralization (plaque-reduction) test and an indirect fluorescent-antibody (IFA) staining test for usefulness in the serologic diagnosis of 34 cases of Colorado tick fever. The cell-culture antigen was as reliable as the mouse-brain antigen, and its preparation was simpler. The CF-antibody titers and the neutralizing-antibody titers tended to be lower and slower to appear than the IFA titers. The IFA method was simple, rapid, and accurate. The IFA titers frequently appeared earlier after onset of illness and reached higher levels than did the CF titers.

All the Dogs owners asked this common question as to how can we identify the Dog Tick Fever? No worries, we will help you. If a dog has tick fever which appears in acute, sub-clinical and chronic stages. Acute will experience symptoms such as respiratory troubles, swollen lymph nodes, loss of weight, fever, bleeding problems, and neurological issues. It appears in the beginning stages of tick fever. In fact, sub-clinical stage of Dog Tick Fever, display zero indication of the disease. So that dont exhibit symptoms and the dog possesses a good immune system, they could potentially fight off tick fever during the sub-clinical period. In the chronic stages, they might display severe symptoms such as anemia, vision difficulties, eye hemorrhaging is one example and lameness, uncontrollable bleeding, limb swelling, and failure of the bone marrow. Then their health condition characterized by low blood-platelet counts. So that chronic ehrlichiosis sometimes succumbs to the ailment.. Beyond that, After ...

Its important to consult your doctor even if signs and symptoms disappear - the absence of symptoms doesnt mean the disease is gone. Left untreated, Lyme disease can spread to other parts of your body from several months to years after infection, causing arthritis and nervous system problems. Ticks also can transmit other illnesses, such as babesiosis and Colorado tick fever.. In the United States, Lyme disease is caused by Borrelia burgdorferi and Borrelia mayonii bacteria, carried primarily by blacklegged or deer ticks. The ticks are brown and, when young, often no bigger than a poppy seed, which can make them nearly impossible to spot.. To contract Lyme disease, an infected deer tick must bite you. The bacteria enter your skin through the bite and eventually make their way into your bloodstream. In most cases, to transmit Lyme disease, a deer tick must be attached for 36 to 48 hours. If you find an attached tick looks swollen, it may have fed long enough to transmit bacteria. Removing the ...
Posted by Marianne Frederick. Any season these fellows are out in abundance is tick season. Unfortunately, some areas of the country didnt have a hard freeze this past winter, so there may be more of these biters than usual. Ticks are mite-like arachnids and are parasitic to mammals. They live in bushes, woodlands and in tall grass, but can also be found in low-lying moist, damp areas. They exist in several sizes, from practically microscopic to the size of a pinky fingernail-and their bites can transmit diseases including Lyme Disease, Babesiosis, Rocky Mountain Spotted Fever, Colorado Tick Fever and Tularemia. If you are bitten, you may get nothing-or you may get what the tick was carrying!. If you enjoy hiking and camping and you take your young children along-or any family member with a compromised immune system-its important to do a tick check after walking or spending time in the woods or tall grass. Ticks attach themselves as you walk through leaves, by bushes or through grass. Once ...
Ticks can transmit a number of diseases to children; these include bacterial (Lyme, RMSF, ehrlichiosis, tularemia), protozoal (babesiosis), and viral (Colorado tick fever) pathogens. The index of suspicion for tick-borne pathogens should be high in children with unexplained fever or dermatologic findings: a childs play or other activities may put them at higher risk of contact with ticks than adults; the history of tick exposure infrequently is elicited; even if a child notes a tick, tick removal may not occur promptly or thoroughly; and children may become more ill with certain tick-borne diseases than adults. ...

Summary Neutralizing antibodies formed after inoculation of man with a purified Colorado tick fever vaccine have persisted in most instances for 5 years or more. Intradermal inoculation of small amounts of vaccine for skin tests, even that long after original vaccination, resulted in a significant rise in titer of neutralizing antibody. There was no evidence of development of hypersensitivity to any of the components in the vaccine. Results of prevaccination skin tests did not differ significantly from those obtained in tests given after several inoculations of vaccine.

Generally speaking, most bugs go dormant in the winter season - great news for outdoor enthusiasts. (Give a cheer, mosquitoes are gone!) But, there is one disease-carrying bug that still remains a threat to gardeners, campers, hikers and walkers: the black-legged tick. Although tick activity is high in the warm months beginning in spring, tick bites in winter are common. After all, ticks need blood to survive; and they will seek out humans, pets and livestock to remain active. Studies suggest that deer ticks hide underneath leaves and on firewood to stay insulated during the winter months. As long as temperatures are above freezing, tick bites and tick-borne illnesses threaten humans and animals. "Diseases transmitted by ticks in North America include: Lyme disease, Rocky Mountain spotted fever, Powassan virus, American boutonneuse fever, tularemia, Colorado tick fever, ehrlichiosis, anaplasmosis, babesiosis, relapsing fever, and tick paralysis."  (Thought Co.
