After several years in veterinary practice, Dr. Johns returned to the University of California at Davis to complete residency training in clinical pathology, becoming a Diplomate of the American College of Veterinary Pathologists in 2007. Dr. Johns continued at the University of California at Davis to earn a Ph.D. in Comparative Pathology. Dr. Johns joined the Department of Comparative Medicine at Stanford University School of Medicine in 2011.
Her research interests focus largely on hematopoietic and mesenchymal stem cell biology, tick-borne bacterial infections and associated hematopathology, and hematology/hematopoiesis of laboratory animal species.
Immunohistochemical evaluation of CXCL12 protein in bone marrow (BM) (A,B) and spleen (C,D) during acute Anaplasma phagocyto-
philum infection in a mouse model. Representative tissue sections from control (A,C) and infected (B,D) mice at 8 days post-infection (dpi) are shown. Mean numbers of BM CXCL12-positive cells are significantly decreased at 8 dpi. No significant change in mean numbers of CXCL12-positive cells was found in spleen.

Cytologic image of fine-needle aspirate of a mesenteric lymph node from a dog. Macrophages (to left of image and inset) contain variably distinct morulae of Neorickettsia helminthoeca organisms. Lymphoid reactivity is also present. (Johns et al, Vet Clin Pathol , 35(2):243-6, 2006).
