Resumo
The abortion and premature death of calves are one of the main factors that cause economic losses to the cattle.
This problem has multifactorial causes, which can be infectious or non-infectious, making it difficult to identify
the agent asit requires proper collection of the material to be sent to specific laboratory for testing. Furthermore,
a full epidemiological investigation is needed to enable a definitive diagnosis. The Listeria monocytogenes causes
occasionally abortion, neonatal septicemia and death in ruminants, other domestic species and also to humans being.
The diagnosis of listeriosis in cattle is based on epidemiological history, clinical signs, pathologic findings in adults,
fetus and placenta, in addition to the isolation of the agent, which defines the diagnosis. The diagnosis may also be
made by agent marking tissue by means of immunohistochemistry. The description of cases and epidemiological
data of listeriosis as a cause of miscarriages and stillbirths in cattle is scarce, which makes it of relevance to conduct a
review of the subject. Thus, this work brings a literature review on the listeriosis and clarifies the diagnostic methods
employed to determine the causes of abortion and neonatal death in cattle.
