12 primary rhesus monkey kidney cells infected with

12

Primary rhesus monkey kidney cells infected with adenovirus 7 (early CPE), 125X
Aggregates of enlarged rounded cells are present in irregular clusters.
13

Primary rhesus monkey kidney cells infected with adenovirus 7 (late CPE), 125X
An increased number of enlarged rounded cells are aggregated into grape-like clusters.
Degenerated cells have fallen off the glass surface.
14

Diploid cells infected with echovirus (early CPE), 125X
A few infected cells have become round and refractile.
15

Diploid cells infected with echovirus (late CPE), 125X
Many of the cells are rounded or stellate and refractile. Degenerated cells have fallen
from the glass surface.
16

Primary rhesus monkey kidney cells infected with echovirus (early CPE), 125X
17
A general rounding of the cells is evident.

Primary rhesus monkey kidney cells infected with echovirus (late CPE), 125X
Note the generalized cell rounding. Many cells are involved in some stage of infection,
and degenerated cells have fallen from the glass surface.
18

Diploid cells infected with herpes simplex virus (early CPE), 125X
A few rounded, swollen fibroblasts are present in a viral lesion.
19

Diploid cells infected with herpes simplex virus (late CPE), 125X
There is extensive cell rounding. Many degenerated cells have fallen off the glass surface.
20

HEp-2 cells infected with herpes simplex virus (early CPE), 125X
Many round swollen epithelial cells are present in several focal areas.
21

HEp-2 cells infected with herpes simplex virus (late CPE), 125X
Note the extensive piling of round swollen epithelial cells into clusters.
22

Primary rhesus monkey kidney cells infected with influenza virus, 125X
The monolayer appears to be normal.
23

Primary rhesus monkey kidney cells infected with influenza virus,
plus guinea pig erythrocytes,125X
Note the adsorption of erythrocytes to the infected cell monolayer.
24

Diploid cells infected with polio virus (Sabin) (early CPE), 125X
Large areas of cell rounding and cell degeneration are present.
25

Diploid cells infected with polio virus (Sabin) (late CPE), 125X
More extensive involvement of the cell monolayer differentiates this monolayer from the earlier one.
26

HEp-2 cells infected with polio virus (Sabin) (early CPE), 125X
The monolayer contains generalized cell rounding.
27

HEp-2 cells infected with polio virus (Sabin) (late CPE), 125X
The monolayer contains numerous areas of infected cells. Many cells have fallen from the glass surface.
