Examples of encephalization in the following topics:

  • Arboviral Encephalitis

    • Arboviral encephalitis are a group of arthropod-transmitted viruses that cause encephalitis (acute swelling in the brain).
    • Arboviral encephalitis are found in many places throughout the world, and include California encephalitis, Japanese encephalitis, St.
    • Louis encephalitis, Tick-borne encephalitis, and West Nile fever.
    • Tick-borne encephalitis (TBE) is an infectious disease of the central nervous system.
    • Sheep ticks (Ixodes ricinus) such as this engorged female transmit encephalitis.
  • West Nile Virus

    • This was until an outbreak in Algeria in 1994, with cases of WNV-caused encephalitis, and the first large outbreak in Romania in 1996, with a high number of cases with neuroinvasive disease.
    • Discuss the causes, symptoms and diseases (West Nile encephalitis, meningitis, meningoencephalitis and poliomyelitis) caused by the West Nile virus (WNV)
  • Rabies

    • Rabies is a viral disease that causes acute encephalitis in warm-blooded animals.
    • Rabies is a viral disease that causes acute encephalitis (inflammation of the brain) in warm-blooded animals.
  • Classic Viral Hemorrhagic Fevers

    • The family Flaviviridae include dengue, yellow fever , and two viruses in the tick-borne encephalitis group that cause VHF: Omsk hemorrhagic fever virus and Kyasanur Forest disease virus.
  • Fungi

    • Cryptococcus neoformans causes severe forms of meningitis and meningo-encephalitis in patients with HIV infection and AIDS.
  • Early Homo

    • During the next million years, a process of encephalization began.
  • Infectious Disease Transmission

    • Biological vectors are often responsible for serious blood-borne diseases, such as malaria, viral encephalitis, Chagas disease, Lyme disease, and African sleeping sickness.
  • Emerging and Reemerging Infectious Diseases

    • However, there was an outbreak in Algeria in 1994, with cases of WNV-caused encephalitis, and the first large outbreak in Romania in 1996, with a high number of cases with neuroinvasive disease.
