Facilitation of infection of monkey cells with poliovirus "ribonucleic acid"
Science (New York, N.Y.)
|January 13, 1961
Abstract:
The plaque titer of poliovirus "ribonucleic acid" on monkey kidney cells cultured in vitro is greatly increased by depleting these cells of calcium and treating the "ribonucleic acid" inoculum with a suspension of any one of several poorly water-soluble substances before inoculation. These undissolved substances apparently facilitate infection by serving as solid vehicles for the "ribonucleic acid."
Insights
Enhancing poliovirus infection involves depleting monkey kidney cells of calcium. Treating the poliovirus ribonucleic acid (RNA) with poorly water-soluble substances significantly increases plaque titers, aiding viral entry.
Area of Science:
- Virology
- Cell Biology
- Biochemistry
Background:
- Poliovirus infection relies on the entry of viral ribonucleic acid (RNA) into host cells.
- Calcium ions play a role in cellular processes, potentially influencing viral infection dynamics.
Purpose of the Study:
- To investigate methods for significantly increasing the plaque titer of poliovirus RNA in cultured monkey kidney cells.
- To explore the role of calcium depletion and specific pre-inoculation treatments in enhancing viral infectivity.
Main Methods:
- Culturing monkey kidney cells in vitro.
- Depleting cultured cells of calcium.
- Treating poliovirus RNA inoculum with suspensions of poorly water-soluble substances prior to cell inoculation.
Main Results:
- A significant increase in poliovirus plaque titer was observed when cells were depleted of calcium.
- Pre-treating the poliovirus RNA inoculum with poorly water-soluble substances further enhanced the plaque titer.
- These substances appear to act as solid vehicles, facilitating RNA-cell interaction and infection.
Conclusions:
- Calcium depletion and the use of poorly water-soluble substances as vehicles are effective strategies for enhancing poliovirus RNA infectivity in vitro.
- These findings offer insights into optimizing viral entry mechanisms for research purposes.

01:10Intracellular Movement of Viruses and Bacteria
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a virus that...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
