Route of Infection Strongly Impacts the Host-Pathogen Relationship.

Live attenuated vaccines play a key role in the control of many human and animal pathogens. Their rational development is usually helped by identification of the reservoir of infection, the lymphoid subpopulations associated with protective immunity as well as the virulence genes involved in pathogen persistence. Here, we compared the course of infection in C57BL/6 mice infected via intraperitoneal (i.

Infection Favors Elimination IL-12/IFNγ-Dependent Pathways.

This study develops an original co-infection model in mice using , the most frequent cause of human brucellosis, and , the agent of African trypanosomiasis. Although the immunosuppressive effects of in natural hosts and mice models are well established, we observed that the injection of in mice chronically infected with induces a drastic reduction in the number of in the spleen, the main reservoir of the infection. Similar results are obtained with - and -infected mice and -infected mice co-infected with , demonstrating that this phenomenon is not due to antigenic cross-reactivity.

Diagnostic imaging algorithm for cervical soft disc herniation.

MR imaging with surface coils is currently the preferred method for the evaluation of cervical soft disc herniation. However, the differentiation between soft disc herniation and osteophytic spurs in the neural foraminal canal is not always obvious on a 0.5 Tesla unit.

Diagnostic imaging algorithm for cervical soft disc herniation.

MRI with surface coils is currently the preferred method for evaluating degenerative cervical spine disease. The differentiation between soft disc herniation and osteophytic spurs is not always obvious, however, on a 0.5 Tesla unit.

Stereotactic radiosurgery of vestibular schwannomas with a linear accelerator.

The authors describe their initial experience with stereotactic radiosurgery of 22 cases with vestibular schwannomas using a linear accelerator. 14 of them with a follow-up of at least one year were studied. 6-9 months after treatment 86% had central tumour necrosis, 71% tumour shrinkage and none of them evidence of tumour growth 3 patients developed reversible facial nerve impairment, 2 had permanent facial numbness.
