Notare le punte che adornano la superficie esterna del virus, che conferiscono l'aspetto di una corona che circonda il virione, se osservate al microscopio elettronico. Un nuovo coronavirus, denominato Coronavirus 2 della sindrome respiratoria acuta grave (SARS-CoV-2), è stato identificato come la causa di un'epidemia di malattia respiratoria ...
Virus infections start when viral particles bind to host surface cellular receptors. [158] Protein modeling experiments on the spike protein of the virus soon suggested that SARS‑CoV‑2 has sufficient affinity to the receptor angiotensin converting enzyme 2 (ACE2) on human cells to use them as a mechanism of cell entry.

The virus can spread to different organs throughout the chicken. [131] The virus is transmitted by aerosol and food contaminated by feces. Different vaccines against IBV exist and have helped to limit the spread of the virus and its variants. [127] Infectious bronchitis virus is one of a number of strains of the species Avian coronavirus. [133]

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [ 1 ] Examples are the common cold , gastroenteritis , corona , flu , pneumonia .
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
Porcine epidemic diarrhea virus (PEDV) 1971 [25] Infects pigs. Caused outbreaks in 1972 [26] and 1978, [27] 2010, 2013, 2014, and 2015. [28] Dogs Enteritis: Canine coronavirus (CCoV) 1971 Cats Feline infectious peritonitis (FIP) Feline coronavirus (FCoV) Cattle: Enteritis: Bovine coronavirus (BCV or BCoV) Humans Severe acute respiratory ...
