Abstract
In order to fulfil the seroprevalence gap on Mycobacterium avium subsp. paratuberculosis infection in ovine dairy farms of Marche region (central Italy), a stratified study was carried out on 2086 adult female sheep randomly chosen from 38 herds selected in Ancona and Macerata provinces. 73.7% flocks resulted infected by a commercial ELISA test (Pourquier, France), with a mean seroprevalence of 6.29% of sampled sheep in both provinces. A higher number of MAP seropositive ewes was recorded in the large herds' consistence than in the small and medium herds' consistence (P = 0.0269), and a greater percentage of infected sheep was obtained among female at early/late than in peak lactation stage (P = 0.0237). MAP infection was confirmed in 12.6% of infected farms by faecal culture. The true sheep-level seroprevalence was 15.1% ± 7.3%.
Highlights
Paratuberculosis, known as Johne’s disease (JD), is a prevalent and economically important chronic, nontreatable inflammatory bowel disease of domestic and wild ruminants as well as other mammals worldwide, including nonhuman primates [1,2,3,4]

Serological investigations have been described as effective tools in the establishment of the prevalence of Mycobacterium avium subspecies paratuberculosis (MAP) infection in a herd, and to screen and confirm the diagnosis of paratuberculosis in animals that present compatible clinical symptoms [44]
Summary
Paratuberculosis, known as Johne’s disease (JD), is a prevalent and economically important chronic, nontreatable inflammatory bowel disease of domestic and wild ruminants as well as other mammals worldwide, including nonhuman primates [1,2,3,4]. It is on the list of “multiple species diseases” notifiable to the World Organization for Animal Health as a ruminant disease of concern [5]. Viable bacteria have been demonstrated in hard and semihard cheese 120 days after production [24]
