ANTI-VIRAL CHEMOTHERAPY - Microbiology Book

In the retrovirus life cycle, the targeting of the specific protease that is necessary for the formation of an infectious virus particle has been particularly successful. Earlier, reverse transcriptase inhibitors had also been successful but the nucleoside analogs cause severe side effects because they also inhibit the host's DNA polymerase.

Feline Leukemia Virus Disease Complex | VCA Animal Hospital

Feline leukemia virus is a virus that infects cats and can cause a variety of diseases in addition to leukemia. It suppresses the immune system and makes cats susceptible to infections and disease, including causing cancers. It is transmitted between cats through the exchange of bodily fluids, although usually an extended period of contact is necessary. It is easy to diagnose, but there is no

FIP: Feline Infectious Peritonitis in Cats

However, in 5-10% (Feline Infectious Peritonitis, 2002) of infected cats, the virus is not so mild. Scientists believe that, in these cases, the virus mutates inside the body, and then the cat's own immune system mounts an inappropriate response to it and aids in its spread.

Haematological changes in infection: tips for interpretation

Certain viral infections, for example infectious mononucleosis, infectious hepatitis and HIV infection may cause severe or protracted neutropenia and pancytopenia due to direct damage of the haematopoietic precursor cells. CMV virus may affect the bone marrow microenvironment through infection of stromal cells, especially fibroblast.

Valganciclovir for the Suppression of Epstein-Barr Virus

Primary infection with Epstein-Barr virus (EBV) infection is usually subclinical; however, EBV is the main cause of infectious mononucleosis. Following acute infection, the virus persists in host B and T lymphocytes, monocytes, and epithelial cells; asymptomatic salivary viral shedding leads to onward transmission .

Role of the BM Microenvironment on Hematopoiesis upon Virus Infection. As described for sterile inflammation and bacterial infections, viral infections may also affect hematopoieisis indirectly via the BM microenvironment. Apart from hematopoietic cells, the BM also contains non-hematopoietic components, such as osteoblasts, mesenchymal stromal

Beclin1 restricts RNA virus infection in plants

Overexpression of a Beclin1 truncation mutant that binds to NIb but lacks the ability to mediate NIb degradation also inhibits virus replication. The Beclin1-RdRp interaction further extends to several RNA viruses. Thus Beclin1 restricts viral infection through suppression and also likely autophagic degradation of the viral RdRp.

Competitive suppression of dengue virus replication occurs

A possible mechanism would involve the first virus taking over the cellular factors required for viral replication or interfering with the replication of a secondary viral infection. The interference of one virus by another during co-infection could differentially induce an antiviral state mediated by IFNs.
