Sentence examples for virus over time from inspiring English sources

They were thus able to track genetic changes in the virus over time, and watch it adapt to its new host species Homo sapiens.

The rabbit population shrank to 100 million, although the rabbits developed resistance to the virus over time and by the early 1990s had rebounded to more than 200 million.

It has been proposed that mutations in the hemagglutinin (HA) and neuraminidase (NA) proteins could have facilitated human to human transmission to the 2009 influenza A (H1N1)v virus, over time [5], [6].

12 The majority of people who get HBV infection after the neonatal period tend to clear the virus over time.

We recommend that future studies observe persistence of the virus over time in the various environmental sites.

Intriguingly, sequence data from this arenavirus showed diversity compatible with a pre-existing relationship between host and virus over time.

In Lesson 4, students explore the evolution of influenza viruses over time, using genomic resources and bioinformatic tools to help answer the question "Why is a new flu vaccine needed every few years?" Throughout the lesson, students have to integrate their understanding of both natural selection and common ancestry.

We will model the dynamics of oncolytic virus replication by ordinary differential equations that describe the development of the average population sizes of cells and viruses over time.
