Abortions in N'Dama cattle due to salmonellosis.

An outbreak of diarrhoea, dysentery, abortion and death among N'Dama cattle is reported. Eight animals involved were examined ante- and/or postmortem yielding salmonella belonging to three serotypes, S. visby, S. hadar and S. taksony. The need for further studies to elucidate the problem of salmonella abortion in cattle in Sierra Leone is highlighted.
