“…We found fifteen herds which included 275 individuals to be seropositive and accordingly the average estimate of within-herd true prevalence was calculated as 14.6% in this study (Table 1). These findings are similar to reports from Germany (21%; Stau et al 2012) and Cyprus (24.6%; Liapi et al 2011). The possible within herd transmission could occur by continuous new Map infection in adult animals and high seroprevalence with eventual contamination of the environment.…”

“…The true individual prevalence was estimated to be 8.3% in the Kars Region (Table 1). The animal-level prevalence rate calculated here is similar to those reported in studies conducted worldwide in small ruminants; especially in sheep (Coelho et al 2007;Liapi et al 2011;Stau et al 2012).…”

“…Thus, the results of this study confirm that Map infection is widespread in sheep herds in the Kars Region. A recent study in Germany reported a between-herd prevalence of 65% (Stau et al 2012). We suggest that the ongoing free and extensive movement of animals such as occurs during spring or holiday seasons together with slack border security practices contribute to elevating Map prevalence among herds.…”

Paratuberculosis, caused by Mycobacterium avium subsp. paratuberculosis (Map), is one of the most prevalent and costly infectious diseases of livestock, particularly sheep and cattle herds. The aim of this study was to estimate true animal, within-herd, and between-herd prevalence of Map antibodies in sheep herds of the Kars Region in the Northeast part of Turkey. A seroprevalence study was carried out using a commercial ELISA kit. Twenty six sheep herds, non-vaccinated against Map, were randomly selected in different regions and in total 450 sheep aged 24 months and more were sampled. Herds were declared positive if one or more sheep in the herd tested positive for Map antibodies. The animal, within-herd, and between-herd apparent prevalences were calculated as 6.2% (95% CI = 4.3 to 8.8%), 10.2% (95 CI = 7.1 to 14.3%) and 57.7% (95% CI = 38.9 to 74.5%), respectively. True prevalences were estimated by conversion from apparent prevalences via the Rogan-Gladen estimator. True animal, within-herd, and between-herd prevalences were calculated as 8.3% (95% CI = 4.7 to 11.8), 14.6% (95 CI = 8.9 to 20.2) and 90% (95 CI = 59.8 to 120.1), respectively. The results provide useful information regarding the prevalence of Map infection in sheep herds in the Kars Region and will hopefully attract the special attention of veterinarians and promote the establishment of an efficient control programme.

“…Suspected Johne's disease in beef and dairy cattle from Europe and Asia were M. paratuberculosis positive in 16.8% of cases (10.9-23.7, I 2 91%) by PCR and culture (Branciari et al, 2008;Kaur et al, 2010;Khan et al, 2010;Munster et al, 2011). Studies of suspect caprine Johne's disease cases from Europe yielded a meta-analysis M. paratuberculosis prevalence of 24.6% (14.2-36.8, I 2 55%) by ELISA (Hartnagel, 2000;Stau et al, 2012). The only swine investigation collected lymph nodes with Johne's disease like lesions at slaughter and reported 4/50…”

Cross reactivity of three antigens of Mycobacterium avium subspecies paratuberculosis with sera of sheep endemic for Johne's disease was evaluated. Out of 40 sheep tested by fecal microscopy, 72.5% were shedding MAP. Using protoplasmic antigens (PPA) from three MAP strains isolated from different livestock species and geographical regions, 90, 77.5 and 2.5% sheep were positive in goat (Indigenous g-ELISA) and cattle (b-ELISA) based ELISA kits and ELISA kit for small ruminant (sr-ELISA), respectively. Only 2.5 and 10% sheep were positive and negative in all the four tests. Native species specific (goat origin novel 'Indian Bison Type' MAP) semi-purified whole cell PPA based ELISA (Indigenous g-ELISA) was superior in reacting with sera of native sheep than the commercial PPA of bovine origin (Allied Monitor Inc., USA) and commercial ELISA kit for small ruminants (ID Vet, France). Lower cross reactivity of antigens originated from US and France emphasized the need to develop tests based on local strain of MAP than strains from different livestock species and geographical regions. This is an important finding against the use of 'Global kits' without validating in local conditions. Study showed that kits developed from local strains of MAP were not only superior but also cost effective and will significantly contribute in programs for the control of JD in native sheep population.
