Comparative susceptibilities of insect cell lines to infection by the occlusion-body derived phenotype of baculoviruses

Journal of Invertebrate Pathology
Dwight E Lynn


Twelve insect cell lines from six species were tested for susceptibility to baculovirus infection by occlusion-derived virus (ODV) phenotype through the use of a typical endpoint assay procedure. ODV from three nucleopolyhedroviruses were prepared by alkali treatment (sodium carbonate) of occlusion bodies (OBs) and the virus preparations were titered on various cell lines. More than a four-log difference was realized for each of theses viruses between the various cell lines. The TN368 line from Trichoplusia ni was only marginally susceptible to ODV from each virus, showing only 3-6 infectious units (IU) per million OBs while the gypsy moth line, LdEp was most susceptible, realizing more than 100,000 IU/million OBs. The other lines tested showed various levels of susceptibility between these two extremes and also varied between the three viruses tested. In additional tests, the ODV were treated with trypsin prior to application to the cells. With most cell lines, this treatment increased the infectivity of each virus by 2-10-fold. Exceptions to this trend included the gypsy moth LdEp line, on which the trypsinized ODV from two of the viruses were slightly less infectious than each virus without trypsin, and the TN-368 line, on w...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
