(springer.com)
  • The majority of studies have focused on specific viruses [ 4 , 5 ] or bacteria [ 6 , 7 , 8 ], with few assessing whether upper airway microbiology predicts clinical symptoms. (springer.com)
  • pathogen

  • The pathogen-containing particles, also called Flügge droplets (after Carl Flügge), are 0,1-2 mm in diameter, and are reduced by evaporation to droplet nuclei - small (smaller than 100 μ in diameter), dry particles that can remain airborne for long periods. (wikipedia.org)
  • Bluetongue virus is an economically important pathogen of cattle and sheep. (wikipedia.org)
  • Pneumonia
  • In Indigenous children hospitalised with pneumonia in Central Australia, we describe the nasopharyngeal detection of viruses and bacteria and assessed whether their presence related to signs of pneumonia (tachypnoea and/or chest in-drawing) on hospital admission and during subsequent days. (springer.com)
  • International Committ
  • The International Committee on Taxonomy of Viruses (ICTV) classifies RNA viruses as those that belong to Group III, Group IV or Group V of the Baltimore classification system of classifying viruses and does not consider viruses with DNA intermediates in their life cycle as RNA viruses. (wikipedia.org)

  • Newcastle
  • Goudarzi, Hossein 2016-12-21 00:00:00 Newcastle disease virus (NDV) is believed to be the cause of fatal poultry disease worldwide. (deepdyve.com)
  • The fusion (F) protein plays a key role in virus pathogenesis, and it is also used for Newcastle disease virus classification. (deepdyve.com)
  • also used for Newcastle disease virus classification. (deepdyve.com)
  • protein
  • Heterologous Expression and Isolation of Influenza A Virus Nuclear Export Protein NEP. (amedeo.com)
  • Cullin-4A is a protein that in humans is encoded by the CUL4A gene. (wikipedia.org)
  • For example, the region of the hepatitis C virus genome that encodes the core protein is highly conserved, because it contains an RNA structure involved in an internal ribosome entry site. (wikipedia.org)
  • classification
  • Though not used by the ICTV, Baltimore classification, which groups viruses together based on how they produce mRNA, is used in conjunction with the ICTV's work in modern virus classification. (wikipedia.org)
  • distinct
  • The taxonomic division is broadly based on antigenic and genetic characteristics, forming four major serotypes or clades, which today are considered distinct viruses. (wikipedia.org)
  • nucleotides
  • A 5' trailer sequence, 50-161 nucleotides long Intergenomic regions between each gene, which are three nucleotides long for morbilliviruses, respiroviruses and henipaviruses, and variable length (1-56 nucleotides) for rubulaviruses. (wikipedia.org)
  • nasopharyngeal
  • In these cases, French investigators utilized improved techniques for recovering the virus from nasopharyngeal aspirates and from stool samples. (wikipedia.org)
  • commonly
  • 1 , 2 It affects boys more than girls (1.4:1) and young children between 6 months and 3 years of age more commonly than younger infants, older children and adolescents. (cmaj.ca)
  • Members of this group include the rotaviruses, renowned globally as the most common cause of gastroenteritis in young children, and picobirnaviruses, renowned worldwide as the most commonly occurring virus in fecal samples of both humans and animals with or without signs of diarrhea. (wikipedia.org)
  • For example, Ajoene has been shown to have activity against the human dermatophyte Trichophyton rubrum, the most common cause of tinea pedis, commonly known as Athlete's Foot. (wikipedia.org)
  • Transmission
  • This investigation provides evidence for person-to-person transmission of Nipah virus. (cdc.gov)
  • Transmission can also be indirect, via another organism, either a vector (e.g. a mosquito or fly) or an intermediate host (e.g. tapeworm in pigs can be transmitted to humans who ingest improperly cooked pork). (wikipedia.org)
