In this work the clinical evolution and the specific serum IgG and IgE antibody responses in
sheep after primary (n= 10) and secondary (n= 4) experimental challenges with the mange
mite Sarcoptes scabiei var. ovis were studied. The primary infection was characterized by
the development of mange lesions in all sheep, a detection of live S. scabiei mites in 70%
skin scrapings taken in week 10 post-challenge (PC), strongly raised and sustained specific
IgG levels and a more moderate but continuous rise in specific IgE levels. Seroconversion …
