[Paratuberculosis eradication programs in Northrhine-Westfalia].

Since 1993 a voluntary eradication program for bovine paratuberculosis is established in Northrhine-Westfalia. After an effectivity control of the serological diagnostics it is combined with the fecal culture since August of 2000. Parallel use of both methods is necessary for a successful eradication. It could be monitored that a high percentage of the newly bought cattle in the herds participating in the eradication program was considered positive. Since paratuberculosis eradication is time and cost extensive besides intensive eradication programs the spread of the disease must be stopped.

[The isolation and differentiation of leptospires from cattle drinking water].

The cultural isolation and identification of leptospires from three water samples of farm wells were described. All three strains isolated belong to the apathogenic species L. biflexa. The cattle stock of these farms (A, B, C) had reacted serologically to serovars hardjo and grippotyphosa. The strain isolated from farm A is a new serovar called krefeldi and belongs to serogroup Doberdo. The strain isolated from farm B belongs to serovar montefiascone of serogroup Botanica and the strain from farm C to serovar bessemans of serogroup Bessemans. It is remarkable that serovar krefeldi with all the sera of farm A (titre up to 1:40) and only with part of the sera of farm B reacted.
