“…An association between maternal vaccination and induction of disease via colostral antibody has been described previously in cattle, e.g. immune-mediated haemolytic anaemia in calves following the use of vaccines against anaplasmosis [20] and babesiosis [21], [22]. In the case of BNP, some cows produce alloantibodies which bind to calf peripheral leukocytes [11], [23] and such alloantibodies have been identified in the sera of PregSure® BVD vaccinated BNP dams [12].…”

Bovine neonatal pancytopenia (BNP; previously known as idiopathic haemorrhagic diathesis and commonly known as bleeding calf syndrome) is a novel haemorrhagic disease of young calves which has emerged in a number of European countries during recent years. Data were retrospectively collected during June to November 2010 for 56 case calves diagnosed with BNP between 17 March and 7 June of the same year. These were compared with 58 control calves randomly recruited from herds with no history of BNP. Multivariable logistic regression analysis showed that increased odds of a calf being a BNP case were associated with its dam having received PregSure® BVD (Pfizer Animal Health) vaccination prior to the birth of the calf (odds ratio (OR) 40.78, p<0.001) and its herd of origin being located in Scotland (OR 9.71, p = 0.006). Decreased odds of a calf being a BNP case were associated with the calf having been kept outside (OR 0.11, p = 0.006). The longer that a cattle herd had been established on the farm was also associated with decreased odds of a calf in that herd being a BNP case (OR 0.97, p = 0.011).

Agglutinins that reacted with red cells from members of a different species (heteroagglutinins) were detected in the serum of bovine fetuses beginning with about 5 % in the fifth month of gestation, with the frequency of reactive sera increasing to about 50 % near term. The sera were able to agglutinate red cells from an increasing number of species as fetal age increased, but only exceptionally equalled the number agglutinated by sera from the dams.Antibodies that reacted with bovine red cells (isoantibodies) were detected in bovine fetal sera (anti-L agglutinin, anti-K' hemolysin). However, no fetal serum was found that agglutinated the red cells of the respective dam.All fetal isoantibodies were inactivated by heat (56"C/30 min) and 2-mercaptoethanol (2-ME) treatment, whereas some heteroagglutinins in serum from one fetus were resistant to inactivation by these methods. This suggests that most of the fetal antibodies were other than IgG.
