Facilitates virus attachment through interactions with glycosaminoglycans. (wikipedia.org)

Bacteria often require a substrate to attach themselves to before they can multiply, and the attachment can be host specific or site specific. (who.int)
This chronic inflammatory disease results from the response to bacteria in dental biofilm and may remain confined to the gingival tissues with minimal tissue alterations or this disease may progress to extreme periodontal destruction with the loss of attachment and alveolar bone. (bvsalud.org)

The virus has been found in various mosquitoes of the Aedes genus, including Aedes africanus , Aedes apicoargenteus , Aedes leuteocephalus , Aedes aegypti , Aedes vitattus , and Aedes furcifer . (virology.ws)

However, there are no approved pharmaceuticals that have shown potent specific activity against the virus, hindering control of the outbreak. (news-medical.net)
As of September 17, 2019, an active outbreak of Ebola virus disease in the Democratic Republic of the Congo (DRC) had resulted in 3,034 confirmed and 111 probable cases of Ebola virus disease, including 2,103 attributable deaths. (medscape.com)

A phishing email is typically a well-thought-out email designed to get the user to open an attachment. (zoho.com)
Viruses are among the smallest microbes, typically ranging from 0.02 to 0.3 micrometer, although several very large viruses up to 1 micrometer in length (megavirus, pandoravirus) have recently been discovered. (msdmanuals.com)

E1/E2 heterodimer binds host apolipoproteins such as APOB and APOE thereby forming a lipo-viro-particle (LVP) (PubMed:25122793, PubMed:29695434, PubMed:24838241). (proteopedia.org)

Overall, the genomic analysis of the virus in this specimen does not change CDC's risk assessment related to the avian A(H5) clade 2.3.4.4b viruses. (cdc.gov)

A bigger threat might come from potential confusion between news reports of the new computer virus and the biological virus that is currently spreading worldwide, he said. (itworldcanada.com)

Fusion with the host cell is most likely mediated by both E1 and E2, through conformational rearrangements of the heterodimer required for fusion rather than a classical class II fusion mechanism (PubMed:16533059, PubMed:29505618, PubMed:24698129). (proteopedia.org)

This phase of the immune response continues until the viruses are eliminated from the body. (adventistreview.org)
General principles to protect ourselves against the invisible offenders include avoiding contact with them, destroying them with soapy water before they enter the body, keeping the immune system functioning optimally through living healthfully and managing stress, and being a loving neighbor by avoiding spreading viruses to others, by God's grace.
