Furthermore, in vivo imaging showed significant viral replication in the skin (tail, feet), producing multiple well-defined pustule lesions with the presence of Guarneri inclusion bodies as confirmed by histology and immunhistochemistry.
In SCID mice inoculated with MPXV-USA/Luc+, luminescent signal was also visible in the abdominal region at 96 hours PI, and it was visible in the tail, feet, and nasal area at 240 hours PI.
Finally, a variety of areas were observed to undergo transient or shifting hypoxia, including the ears, tail, rump, feet, and scruff.
The scientists then induced pain in males or females by applying a small dose of inflammatory compounds to the cheek, tail, foot, or genitals.
However, blood can be collected from tail, foot, or saphenous vein of an un-anesthetized mouse by restraining the animal.
Blood samples were collected from four sampling sites, tail, foot, lateral tarsal (saphenous), and heart, in succession from anesthetized mice.
However, the variability in vessel diameter could be a factor contributing to the differences that existed between blood leukocyte counts collected from the heart, tail, foot, and saphenous.
To accomplish this, blood samples were collected from C57BL/6 male and female mice using the techniques of cardiac puncture and venous puncture of the tail, foot, and saphenous.
In this study, we used an infrared heat lamp to raise the surface temperatures of the tail, foot, and leg, to 29 - 30°C.
There were no significant differences in total leukocyte counts among the samples taken from the tail, foot, and saphenous veins as compared to each other.
Because there were no significant differences between blood samples collected from the tail, foot and saphenous veins, only two of these techniques, i.e. tail and saphenous, were applied along with cardiac puncture in this part of the study.
