Impetigo and furunculosis appeared in a dairy cattle herd in associati
on with intensive showering of the lactating cows during the summer mo
nths. Heifers and dry cows in the same herd, as well as those in a nei
ghbouring herd in the same village, which was not showered and served
as a comparison herd, remained unaffected. Skin lesions declined with
the termination of showering. Only six animals [three cows (7.3%) and
three first-calving cows (20%)] had to be treated parenterally with an
tibiotics.
