Neospora

This computer program will show more informatio about the way and the degree of contamination with Neospora caninum. Neospora causes reproduction disorders such as still birth, mummification and abortion. Premature birth and death seems also to be related to Neospora. In some cases Neospora infections behaves like a abortion storm.
 
Based on blood sample results and identification data the program will be helpful in tracing the moment of introduction of a Neospora caninum infection on a dairy farm. Blood samples are grouped in categories negative, low positive and high positive. Analysis of blood sample results is based on family ties, date of birth (or date of arrival) and zootechnical data.

Family ties

Based on family ties and blood sample results animals can be grouped in congenital infected and postnatal infected animals. In most cases the computer program will be able to categorise an animal to congenital or postnatal infected. The remaining cases can be categorised manually using the family tree shown by the computer program, which includes blood sample results.

Date of birth

A graphical distribution of blood sample results per month of birth can show an indication about the periode an Neospora infection was introduced. In this case ther will be a cluster of postnatal infected animals. Also a group of congenital infected animals is seen two years later.
When the kind of clustering as descriped is not shown and almost al positive animals are congenital infected, often just only some families are infected transferring their infection to their offspring.

Zootechnical data

In case of postnatal infection the moment of introduction of the infection can be estimated by looking at common factors of the postnatal infected group. Location of housing, feeding, the moment from which the negative offspring becomes positive, moment of abortion storm and differences between purchased animals and farm born animals must be taken in account.

Link to Inseman

During datamanagement in the Neospora computer program selections of positive animals and negative animals are set in the InsemAn database. These selections can be analyzed seperately in InsemAn.
