I was hoping that someone could help me sort out some conflicting test results, and figure out the likelihood of a lab error vs. Most (90 in one study) of these people have positive blood tests for HSV with no history of symptoms or outbreaks. Psychological Stress As A Trigger For Herpes Zoster: Might The Conventional Wisdom Be Wrong?

A PCR test can be done on cells or fluid from a sore or on blood or on other fluid, such as spinal fluid. A positive herpes IgG test only tells you that at some point in time you acquired the herpes virus (1 or 2 or both depending on your results). This tab also contains the file for my 565 page eBook, with the same title, Foundations of Virology. This tab also contains .pdf files of several of my old papers that are not available on the Internet. The virions are drawn to scale, but artistic license has been used in representing their structure. Virions have accumulated in the normally narrow spaces between neurons as a result of budding from the intracytoplasmic (Golgi) membranes and exocytosis via membrane fusion.
This is an ultra-thin section of the salivary gland of an Aedes triseriatus (Say) mosquito, 21 days after infection, showing large numbers of virions within the lumen of an upstream divereticulum of the salivary space. This image has been "borrowed" so often for various public uses that many people think that all Ebola virions look just like thisa€”indeed, in the film Outbreak every virion seen looked just like this.
In this case, some of the filamentous virions are fused together, end-to-end, giving the appearance of a "bowl of spaghetti." Negatively stained virions.
These inclusions may be dramatic in scale, beautiful in appearance, but this is "a terrible beauty" (Yeats).


This is the same ultra-thin section of an infected cell in a cell culture as above, only colorized. Negatively stained virions showing surface projections which contain the receptors by which the virus attaches to host respiratory tract epithelial cells. This is an ultra-thin section of the brain of a mouse infected with La Crosse virus (family Bunyaviridae, genus Bunyavirus) at six days post-infection when the mouse was moribund. Virions have been penetrated by the negative contrast stain; the fine surface projections and envelope (derived from Golgi membrane of the infected cell) that are characteristic of viruses like this (family Bunyaviridae, genus Bunyavirus) are clear, but viral nucleocapsids, which are very fine strands, are not. Antibody tests are sometimes done but are not as accurate as a viral culture at finding the cause of a specific sore or ulcer.
Herpes is not a blood borne infection so therefore using pcr testing for routine testing of herpes is pretty much useless. Given the severity of the illness and the availability of effective therapy, there is a need for a rapid and accurate diagnostic test for HSV encephalitis (HSE).
This is a 180Mb .pdf file, which takes about 2 minutes to download on my home computer, but it is the lowest resolution (smallest file) possible.
In some, the cross-sectional structure of capsid and envelope are shown, with a representation of the genome; with the very small virions, only their size and symmetry are depicted.
Virions have accumulated in the space between cells as a result of budding from the surface membrane of infected cells.
In this infection large numbers of the 60 nm (nanometer) spherical virions crowd the salivary space, ready to be transmitted to the next vertebrate host when the mosquito seeks a blood meal.
In fact, Ebola virions are extremely varied in appearance -- they are flexible filaments with a consistent diameter of 80 nm (nanometers), but they vary greatly in length (although their genome length is constant) and degree of twisting.
In fact, Ebola virions are extremely varied in appearance a€” they are flexible filaments with a consistent diameter of 80 nm (nanometers), but they vary greatly in length (although their genome length is constant) and degree of twisting. Here, virion budding is occurring "perpendicular" to the plane of the plasma membrane -- in other instances budding has been seen to occur in "parallel" fashion, with the entire virion nucleocapsid first lying in contact with the inner face of the plasma membrane and budding occurring along its entire length.
Herpes simplex virus infection becomes latent, that is it becomes invisible after a fever blister episode, but the virus persists, in ganglia at the floor of the brain; when conditions are right the virus can re-emerge.
Adenoviruses replicate in the nucleus of cells and as seen here they may reach extraordinary concentrations. Rotaviruses replicate in the cytoplasm of cells, usually in association with granular inclusions ("virus factories") as shown here.
Virions (100nm in diameter) are accumulating within intracytoplasmic (Golgi) vesicles as a result of budding.
HSV PCR detection from CSF is a sensitive and specific alternative for detection of disease involving the CNS, as well as oral, genital, ocular, and other sites.
If a viral culture taken at a clinic from an active herpes lesion is positive for herpes simplex, then this makes the diagnosis.
Polymerase chain reaction (PCR) can be used to detect VZV DNA rapidly and sensitively in properly collected skin lesion specimens; however, PCR testing for VZV is not available in all settings.
The highest resolution file, suitable for printing, is also available, but I would have to send it via Dropbox. Classical negative contrast images of coronaviruses are really not the way they look when in their native state. In this infection very large numbers of the 60 nm (nanometer) spherical virions are produced quickly and as quickly the cells are destroyed.
When isometric particles are crowded together they form six-fold, three-dimensional arraysa€”when such arrays are sectioned one sees various planes of section because the pseudocrystalline array is not perfect.
With both detection methods, lesion duration and morphology were associated with HSV detection.


This is a qualitative assay; results are reported either as negative or positive for herpes simplex virus (HSV) type 1 or HSV type 2, or HSV indeterminate. Wald et al showed in their 1997 paper that the PCR test was almost 300 more sensitive in picking up actual viral material from vaginal specimens than was the viral culture.
In these instances, a history of VZV exposure or of a rash that began with a dermatomal pattern, along with results of VZV antibody testing at or before the time of rash onset may help guide the diagnosis. This test can be used to diagnose genital infection with herpes simplex virus type 1 or type 2.
Here, the top micrograph represents the classical image and the bottom micrograph the way coronaviruses look in their native state. Native virions are actually so heavily covered with peoplmers that virions might not be recognized if only the classical images are in mind. Cell culture or PCR test may give a false-negative result if the sores have begun healing or if you are recently infected.
Using these experiments, we more accurately computed the test sensitivity, specificity, and misclassification rates. This is an ultra -- thin section of the small intestine of an infant mouse at two days post-infection when the mouse was moribund. The most important fact to know in terms of Herpes testing is that blood testing with an IgG test is the BEST test for diagnosing the disease. Virions have accumulated upon the plasma membrane of this intestinal epithelial cell as a result of transport from sites of virion production in the endoplasmic reticulum and exocytosis via membrane fusion -- the virions then stick to the outer surface of the cell.
In the past, type-specific blood tests were not always accurate because they confused other herpes virus antibodies such as varicella zoster (chicken pox) , Epstein Barr, or mononucleosis for herpes simplex (Types 1 and 2) antibodies. Know that having an accurate sexual history as well as a description of your symptoms is very important as your health care provider evaluates you.
The PCR test locates the DNA of the herpes virus; hence, this common way of testing for the herpes simplex virus offers highly accurate results. There is a new test, dubbed the silver pap that includes a herpes PCR swab test in addition to the GC (gonorrhea and Chlamydia) tests that are performed at this time. Whereas the culture requires quick access to the lesions, PCR does not require as many virus particles for accurate testing. This allows more time between lesion outbreak and sample collection with a lower false negative rate. One study found that herpes cultures give FALSE NEGATIVE results 76 of the time when compared to the more accurate PCR test described below. The detection of Herpes Simplex (HSV) from ocular specimens is essential for prompt and accurate therapy. In our laboratory, all clinical ocular samples suspected of possible HSV infection are tested with standard cell culture, ELVIS, and PCR. Both Herpes simplex type 1 (HSV 1) and Herpes simplex type 2 (HSV 2) can infect the genital area. Yes, there are blood tests for Herpes Simplex Virus 1 and 2 (HSV1 and HSV2) but they are not recommended in adolescents or adults who are asymptomatic. If a PCR test from a swab of a sore is positive, you can be pretty sure herpes is the cause. Other accurate tests for HSV-2 may also be available through your local healthcare provider.
