A vaccine to protect a mammal against neosporosis, comprising an immunologically effective amount of an homogenate prepared from cells of Neospora, which homogenate is capable of inducing a protective response against neosporosis in a mammal, and a veterinarily acceptable carrier.

A method for preparing a vaccine that protects a mammal against neosporosis, comprising homogenizing cells from Neospora to produce an homogenate capable of inducing a protective response against neosporosis in a mammal, and combining an immunologically effective amount of the homogenate with a veterinarily acceptable carrier.

A method for protecting a mammal against neosporosis, comprising administering to the mammal a vaccine comprising an immunologically effective amount of an homogenate prepared from cells of Neospora, which homogenate is capable of inducing a protective response against neosporosis in a mammal, and a veterinarily acceptable carrier.

A combination vaccine for protecting a mammal against neosporosis and, optionally, one or more other diseases or pathological conditions that can afflict the mammal, which combination vaccine comprises an immunologically effective amount of a first composition comprising an homogenate prepared from cells of Neospora, which homogenate is capable of inducing a protective response against neosporosis in a mammal;

• an immunologically effective amount of a second composition capable of inducing a protective response against a disease or pathological condition that can afflict the mammal;
• and a veterinarily acceptable carrier.

A kit for vaccinating a mammal against neosporosis, comprising a first container having an immunologically effective amount of an homogenate prepared from cells of Neospora, which homogenate is capable of inducing a protective response against neosporosis in a mammal, and a second container having a veterinarily acceptable carrier or diluent.

An antibody specific to an antigenic component present in an homogenate of Neospora cells.
