Which viruses are aerobic?

Which viruses are aerobic?

First, it is necessary to classify viruses according to their response to hypoxia – some viruses are strictly aerobic (influ- enza viruses), some aero-anaerobic (HIV) and others strictly anaerobic.

What class of virus is polio?

Class: Pisoniviricetes
Order: Picornavirales
Family: Picornaviridae
Genus: Enterovirus

Do poliovirus cells respire oxygen?

A study of poliovirus found that polio infection rapidly decreases (45% decrease) cellular oxygen consumption (and thus energy production through cellular respiration) by inhibiting succinate dehydrogenase (55% decrease in activity) and blocking mitochondrial electron transport at or between complexes I and III.

Is polio a non enveloped virus?

Poliovirus, the causative agent of paralytic poliomyelitis, is a small non-enveloped virus, with a single strand RNA genome encased in an icosahedral protein capsid.

Can viruses live in oxygen?

In general, viruses that naturally infect and replicate in tissues with high oxygen content are impaired by hypoxic environments.

Do viruses like oxygen?

Cellular detection of oxygen and their response to low oxygen levels can exert a significant impact on virus infection. Generally, viruses that naturally infect well-oxygenated organs are less able to infect cells under hypoxic conditions.

How long does polio virus survive in the environment?

Poliovirus may survive in soil for weeks to months, often longer than in water [21]. Survival in soil is adversely affected by increased temperature, decreased moisture, low organic content, exposure to sunlight, and the presence of aerobic bacteria.

Can bacteria survive in pure oxygen?

Anaerobic bacteria live in an environment devoid of oxygen and to anaerobic bacteria even ordinary oxygen is toxic. When anaerobic bacteria is engulfed by clusters of oxygen composed of 100% pure oxygen and is bombarded with electrons shots, it quickly dies. Aerobic bacteria live in normal air containing 21% oxygen.
