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.
Some viruses can "hide" within a cell, which may mean that they evade the host cell defenses or immune system and may increase the long-term "success" of the virus. This hiding is deemed latency. During this time, the virus does not produce any progeny, it remains inactive until external stimuli—such as light or stress—prompts it to activate.
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
Life cycle. Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa.Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime.
The inner circuit illustrates the fully haploid "apogamic" life cycle. Both cycles exhibit all developmental stages. Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution.
When infected, the host cell is forced to rapidly produce thousands of copies of the original virus. [75] Their life cycle differs greatly between species, but there are six basic stages in their life cycle: [26]: 75–91 Attachment is a specific binding between viral capsid proteins and specific receptors on the host cellular surface. This ...
More than 40 years after its premiere, The Facts of Life is still giving Us something to talk about. The sitcom debuted on NBC in August 1979 as a spinoff of Diff'rent Strokes. The Facts of Life ...
Other antiviral drugs target different stages of the viral life cycle. HIV is dependent on an enzyme called the HIV-1 protease for the virus to become infectious. There is a class of drugs called protease inhibitors, which bind to this enzyme and stop it from functioning. [92] Hepatitis C is caused by an RNA virus.
