STUDIES ON RESISTANCE TO BACTERIAL INFECTIONS IN ANIMALS INFECTED WITH RICKETTSIAE [PDF]

The Journal of Experimental Medicine, 1956
Data are presented, demonstrating that infection with Rickettsia typhi brings about a reduction of the death rates and a prolongation of the time of survival in animals subsequently challenged with Pasteurella pestis or Pasteurella tularensis. This interference with bacterial infection by previous rickettsial infection does not appear ...

‘Reservoir dogs’: The emerging zoonotic risk associated with European dog imports to the UK

Veterinary Record, EarlyView.
Abstract Background The movement of dogs from continental Europe to the UK poses a growing public health threat due to the associated risk of disease incursions. Current legislation is insufficient to address the risks and pre‐import control measures are focused only on rabies virus and the fox tapeworm Echinococcus multilocularis. Methods We conducted
