Pope John Paul is reported to be in stable condition after treatment for a high fever caused by a urinary tract infection.
Vatican officials were quoted by Vatican radio and Italian news agencies early Friday as saying the pope responded well to antibiotics prescribed by doctors. The 84-year-old pontiff has been in poor health for some time.
A small crowd gathered at the edge of Saint Peter's Square Thursday night to pray for the pope.
Earlier this week, doctors inserted a nasal feeding tube into the pope to boost his strength and help him recover from February's throat surgery to correct breathing problems.
The pope has suffered from severe arthritis and Parkinson's Disease for several years. He has been hospitalized twice in the last two months.Some information for this story provided by AP.
