Behavioral thermoregulation in mice inoculated with influenza virus

Behavioral thermoregulation in mice inoculated with influenza virus.

Mice housed at 30 degrees C and inoculated with a mouse-adapted influenza virus show a fall in body temperature (Tb) and a decrease in food intake to almost 0 grams per day. This study tested whether the fall in Tb could be accounted for by the decreased food intake and whether the fall in Tb was due to a decrease of thermoregulatory set point or to an inability to maintain Tb at set point leve...

Monitoring virus harvesting time in embryonated chicken eggs inoculated with avian influenza H9N2 vaccine strain

Knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. The present study aimed to evaluate the best harvesting time of H9N2 avian influenza virus (AIV) vaccine strain inoculated in specific pathogen free (SPF) embryonated chicken eggs (ECE)s. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated into 336, 11-day old ECE...

Streptococcus Infection Occurring in Ferrets Inoculated with Human Influenza Virus *

The recovery of a filtrable virus from children with influenza has been described in other papers" T,the virus was isolated by means of the intranasal inoculation of ferrets with nasopharyngeal washings. The ferrets reacted to the washings with an acute respiratory infection, followed by recovery. After the virus had been transmitted in series through ferrets for' several generations, the react...
