Causes of death in calves with experimentally induced bovine neonatal pancytopenia (BNP).

The objective of this study was to identify the different causes of death in calves affected with bovine neonatal pancytopenia (BNP). A total of 51 precolostral calves were fed with colostrum from cows which had lost at least one calf after parturition due to BNP in previous lactations. Clinical BNP could be induced in 71% (36/51) and subclinical BNP in 20% (10/51) of the calves.

Congenital infection with Anaplasma phagocytophilum in a calf in northern Germany.

Anaplasma phagocytophilum is a Gram-negative, obligate intracellular tick-transmitted bacterium that replicates in neutrophils. It causes tick-borne fever (TBF) in sheep and cattle, but also elicits febrile disease in humans as well as in other domestic animals such as dogs, horses, and cats. Although increasingly recognized in Europe, the first laboratory-confirmed case of TBF in cattle from Germany has been published only recently.
