E-9, CV-B5, and E-30 were the most common serotypes detected for aseptic meningitis from 2009 to 2010. EV-A consists of 25 types, EV-B 63 types, EV-C 23 types and EV-D of 5 types. There were no other bacterial or viral infectious etiologies in these cases. The VP1 capsid protein is the most external and immunodominant of the picornavirus capsid proteins and contains neutralization epitopes. In comparisons with viral cultures, PCR is more accurate with a sensitivity and specificity approaching 100% –. Inflammation of heart muscle (myocarditis), low blood pressure, hepatitis, and meningitis sometimes complicate the illness. Routine investigations of blood, urine and cerebrospinal fluid were done along with throat swabs, rectal swabs.
Lancet. HFMD cases were defined as those with a clinical syndrome of mild fever, painful oral lesions and rash, sores, or blisters on the body. Wang VR, Tuan YC, Tsai HP et al. The epidemic pattern of HEV, along with the clinical severity associated with some serotypes was also analyzed. Ophthalmol Dig. Inflammation of heart muscle (myocarditis ), low blood pressure, hepatitis, and meningitis sometimes complicate the illness. On 16 March 2007 the FDA cleared the first NAAT for detection of EV RNA, the Xpert EV assay (Cepheid, Sunnyvale, CA).
Collected specimens were delivered to Omsk virological laboratory and stored at −80 °C. The Clinical Research Ethics Committee of the National Cheng Kung University Hospital (Tainan, Taiwan) approved the study protocol. None of them were immunocompromised. Coxsackievirus infection is associated with meningoencephalitis, a neurological disease characterized by inflammation of both the meninges and brain . HEVs can also cause respiratory diseases such as an exacerbation of asthma, apnea, respiratory distress, pneumonia, otitis media, bronchiolitis, croup, parotitis, pharyngotonsillitis, and pleurodynia. Of the 54 CSF specimens selected, 28 (52%) were positive for EV isolation from cell culture whereas 41 (76%) were positive by the in-house RT-PCR assay and 43 (80%) were positive by the new Penter RT-PCR test (52 versus 76 versus 80%; P = 0.003). For CVA-9 to re-enter the population of Alberta in 2010, either the new isolate was an immune escape mutant against which the population had no prior immunity, or the herd immunity had declined below the threshold.
Kono R, Uchida Y. EV was detected in 461 (19%) of all patients and in 321 (66%) of patients with suspected HFMD and herpangina. Although cases of suspected EV71 infection were widely spread within the Sydney metropolitan area, Sydney’s northern beaches, central parts of Western Sydney and the eastern suburbs experienced more intense activity. cDNA synthesis and detection of human enteroviruses (HEVs) was performed as previously described (15-18). An internal control provided by the manufacturer was tested with a duplicate sample after RNA extraction to check the absence of RT-PCR inhibitors in each specimen tested. Enteroviruses typically demonstrate a marked seasonality in temperate climates, with a typical enterovirus season in the temperate countries in summer and autumn (10,14,15,17,18). The direct EV serotyping from CSF of patients with suspected meningitis was performed with different methods developed for direct investigation of clinical material, including nested PCR we have developed for amplification of the whole VP1 sequence.
The polyprotein consists of P1, P2, and P3 regions, which encodes structural proteins, VP4, VP2, VP3, VP1, and non-structural proteins, 2A, 2B, 2C and 3A, 3B, 3C, 3D, respectively. On physical examination, blisters were found on hands and feet. Echovirus type 30 (ECHO30), which belongs to the EV-B species, is recognized as the leading cause of viral aseptic meningitis in both children and adults. Some schools, colleges, and universities have policies requiring vaccination against meningococcal disease as a condition of enrollment for either incoming first-year students living in residence halls or all incoming first-year students. Participating laboratories are asked to report detections monthly to NESS, as well as demographic (age, sex, and state) and laboratory (specimen collection date, specimen type, virus type) data. In some cases, the lesions involved the spinal cord (three cases) as well as the thalamus (two cases) and putamina (one case). In November 2006, a 37-year-old woman without serious past illness sought treatment at our hospital with hand tremor, unsteadiness, and a 2-day history of headache (day 1).
E. CSF in EM is characterized by increased white blood cell count in contrast with normal or near-normal CSF protein and glucose levels. Only two had increased CSF protein levels, and low CSF/blood glucose ratios were found in all but two cases. Five ECHO30 clinical strains were clustered with the Guangdong environmental strains but diverged from strains from other regions, suggesting that this subcluster of viruses most likely originated from the circulating virus in Guangdong rather than having been more recently imported from other regions. After the viruses in the sewage samples were concentrated and isolated, molecular identification was used to detect and type the NPEVs.
