الملخص EN

Influenza A virus infections were reported in poultry and equines in Sudan.

To investigate the seroprevalence of this viral infection in poultry, equines, camels and other farm animals; sera were screened for antibodies to influenza A virus using ELISA.

A total of 916 blood samples were randomly collected from cattle (n=184), camel (n=184), goat (n=92), sheep (n=92), poultry (n=92), donkey (n=78), and horses (n=194).

Samples were collected from Khartoum, Gezira, River Nile, Butana, Kordofan and Darfur.

Antibodies to influenza A virus were detected in 100% (92/92) of tested poultry sera 37.6 % of horses and 42.3 % of the donkey’s sera.

For equine sera, the overall prevalence rate of influenza A virus antibodies was 39% (106/272).

The highest overall seroprevalence (73.2%) was observed in Atbara followed by Gazira (41.4%).

None of screened cattle, sheep, goats and camel sera were found positive for influenza A virus antibodies.

It was concluded that influenza A infection is existing in poultry, donkey and horses.
