Ans. The family of uncommon progressive neurodegenerative brain illnesses known as transmissible spongiform encephalopathies (TSEs) or prion diseases affects both humans and animals. They invariably result in death and have protracted incubation periods before symptoms appear. Prions, improperly folded proteins, which accumulate in the brain and produce brain damage and the disease's recognizable symptoms, are thought to be the cause of TSEs.

  • The neurological condition in cattle known as bovine spongiform encephalopathy (BSE), sometimes referred to as mad cow disease, is brought on by prions. 
  • Prions are defective protein molecules that may spread their erroneous structure to other versions of the same protein, making them contagious.
  • A degenerative neurologic condition affecting cows is called BSE.  
  • Progressive denotes a problem that worsens with time.  
  • The term "neurologic" refers to injury to the brain and spinal cord of the cow's central nervous system. 
  • The healthy prion protein transforms into a dangerous, aberrant form.  
  • The aberrant prion is completely unknown to the ill cow's body.  
  • The illness cannot be fought off by the cow's body if it is unaware that it is there. 
  • Incoordination is a typical indication of BSE in cows. 
  • An ill cow has difficulty standing and walking.  
  • As a sick cow may sometimes exhibit extremely agitated or aggressive behavior, BSE is frequently referred to as "mad cow disease."
  • When a cow contracts the aberrant prion, it typically takes four to six years before it begins to exhibit BSE symptoms.  
  • The incubation phase is what we refer to as.  
  • A cow's BSE cannot be detected by gazing at it during the incubation stage.  
  • A cow generally succumbs to the illness between two weeks to six months of first exhibiting signs.  
  • BSE has no known cure, and there is no vaccination to protect against it. 
  • There is currently no accurate method for testing for BSE in a live cow.  
  • When examining a cow's brain tissue under a microscope after it has passed away, researchers can determine if it has BSE by observing the spongy texture.

Biological Classification

The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
