Concurrent reactivation of herpes simplex and varicella zoster viruses is rare. Here, we describe the case of an elderly patient with herpes labialis and herpes zoster manifesting as a right-side facial eruption with vesicles and crusting. The loop-mediated isothermal amplification (LAMP) assay demonstrated the presence of both herpes simplex virus type 1 and varicella zoster virus in swab samp...

BACKGROUND Herpes simplex virus (HSV) is the most common cause of acute sporadic encephalitis in the United States. PCR of DNA extracted from cerebrospinal fluid (CSF) allows for reliable diagnosis of herpes simplex encephalitis (HSE). A faster turnaround time for HSE testing would improve patient management and lead to better outcomes. The aims of this study, therefore, were to develop a micro...

INTRODUCTION Herpes simplex virus (HSV) and varicella zoster virus (VZV) are responsible for a variety of human diseases, including central nervous system diseases. The use of polymerase chain reaction (PCR) techniques on cerebrospinal fluid samples has allowed the detection of viral DNA with high sensitivity and specificity. METHODS Serial dilutions of quantified commercial controls of each ...

PURPOSE To detect simultaneously herpes simplex virus type 1 (HSV-1), type 2 (HSV-2), cytomegalovirus (CMV), and varicella-zoster virus (VZV) in ocular specimens suspected of indicating viral infection, and to compare the results of multiplex polymerase chain reaction (PCR) with those of uniplex PCR. METHODS Forty specimens, collected from 33 patients with clinically suspected herpes virus oc...

Cerebrospinal fluid specimens from 226 patients with suspected viral infections of the central nervous system (CNS) were tested by polymerase chain reaction (PCR) to identify the most frequent viruses involved in these infections. A positive PCR result was obtained in 18 patients (7 cases positive for herpes simplex viruses, 5 for enterovirus, 3 for JC virus, 2 for varicella-zoster virus, and 1...

BACKGROUND To study the value and safety of aqueous humor polymerase chain reaction (PCR) analysis for Herpes simplex, varicella zoster, cytomegalovirus, Epstein-Barr virus and Toxoplasma gondii in patients with uveitis. METHODS Records of 45 consecutive patients with anterior and posterior uveitis who underwent AC paracentesis with PCR were reviewed. The main outcome measure was frequency of...

Test ulcers with culture or PCR Genital and oral lesions consistent with herpes simplex lesions are relatively common in my practice. Before PCR testing was available, ulcers could be tested via culture—which took too long to be immediately useful—or via Tzanck smear, which helped greatly if multinucleated giant cells were seen. However, both tests were relatively insensitive. As this Clinical ...

OBJECTIVE To compare the relative proportions of varicella zoster virus (VZV) and herpes simplex viruses in specimens obtained from the genital lesions of adults presenting with presumed genital herpes infection. METHODS Swabs of genital lesions from 6210 patients attending general practices, infectious diseases clinics within hospitals, or sexual health centres for treatment of their genital...

We performed a real-time PCR assay to detect herpes simplex virus (HSV) DNA, and compared it prospectively with a nested PCR assay in 164 clinical samples (109 cerebrospinal fluid and 55 sera) from patients suspected of having neonatal HSV infection or HSV encephalitis. In 25 of 164 samples, HSV DNA was detected by the nested PCR assay. All samples positive for HSV DNA in the nested PCR assay w...

BACKGROUND Herpes simplex virus infections are very common worldwide. The virus can cause infection in various body parts, especially eyes and the nervous system. Therefore, an early diagnosis and highly sensitive method is very helpful. OBJECTIVES The present study sought to investigate the efficiency of Real-time TaqMan probe PCR in the diagnosis of HSV infection in suspected patients. PA...
