Pneumoviridae (from Greek pneumo-'lung' + -viridae 'virus', from Latin, 'poison, slimy liquid') [2] is a family of negative-strand RNA viruses in the order Mononegavirales. [1] [3] Humans, cattle, and rodents serve as natural hosts. [4] Respiratory tract infections are associated with member viruses such as human respiratory syncytial virus.
Viral pneumonia is a pneumonia caused by a virus. Pneumonia is an infection that causes inflammation in one or both lungs. Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [ 1 ]
Virus factors are largely influenced by viral genetics, which is the virulence determinant of structural or non-structural proteins and non-coding sequences. For a virus to successfully infect and cause disease in the host, it has to encode specific virus factors in its genome to overcome the preventive effects of physical barriers, and ...
The genome organization and RNA synthesis of order Mononegavirales. A virus is a member of the order Mononegavirales if [2] [3]. its genome is a linear, typically (but not always) nonsegmented, single-stranded, non-infectious RNA of negative polarity; possesses inverse-complementary 3' and 5' termini; and is not covalently linked to a protein;
Pneumonia is most often caused by a bacterial infection. The bacterial infection occurs mainly after a viral infection. Some examples are canine distemper virus, adenovirus type 1 and 2, parainfluenza virus and feline calicivirus. [2] Those viral infections cause lesions in the airways that allow bacteria to enter the respiratory system more ...
Pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae. [1]S. pneumoniae is a common member of the bacterial flora colonizing the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. [2]
An example of a Class III viral fusion protein is the rabies virus glycoprotein, G. [6] Class IV: Class IV viral fusion proteins are fusion-associated small transmembrane (FAST) proteins. They do not form trimers of hairpins or hairpin structures themselves, and they are the smallest known viral fusion proteins.
[13] [15] Pneumonia is also the leading cause of death in children less than five years of age in low income countries. [15] The most common cause of pneumonia is pneumococcal bacteria, Streptococcus pneumoniae accounts for 2/3 of bacteremic pneumonias. [16] Invasive pneumococcal pneumonia has a mortality rate of around 20%. [14]
