Summary:Alternative diagnostic tools and interesting epidemiological assumptions were associated with an outbreak of Johne′s disease. In a buffalo herd infected with paratuberculosis, seven clinically affected animals and 21 animals with anti- Mycobacterium avium ELISA reactions were identified. Total herd included 203 buffaloes. Most lesions were comparable to those described in buffaloes and cattle affected by Johne′s disease. Water buffalo behaviors such as communal nursing and allosuckling may be additional risk factors for this disease. Detection of positive Ziehl–Neelsen staining and anti- M. avium immunolabeling in rectal biopsies from one buffalo with paratuberculosis are highlighted as auxiliary diagnostic tools for Johne′s disease in live animals.
