متن کاملThe Effect of Bilateral Suprarenalectomy in Adult Albino Rats on the Natural and Acquired Resistance to Bartonella Muris Anemia
Normal adult Wistar rats (non-carrier stock) are readily infected with Bartonella muris and develop a severe anemia if large amounts of infecting material are used. The normal adult rat of Wistar stock possesses a relatively high natural resistance to spontaneous infection with this organism. Bilateral suprarenalectomy in Wistar rats lowers the natural resistance to a subsequent infection with ...
