Reduced emergence of isoniazid resistance with concurrent use of thioridazine against acute murine tuberculosis.

abstract：:Attachment of giardias to intestinal cells has been difficult to study because of a lack of a convenient in vitro model. We developed an assay for attachment of radiolabeled trophozoites to IEC-6 cells that can be done in microtiter trays. Attachment was confirmed by scanning and transmission electron microscopy. Trop...
