Salmonella and shigella bacteraemia in Zimbabwe.

In patients with HIV infection, non-typhoidal salmonellae are a recognised cause of bacteraemia. This association was initially demonstrated in the United States, but has more recently been found in Kenyan patients. This prompted us to review the cases of patients with enterobacteriaceae bacteraemia admitted to Parirenyatwa Hospital, Harare. Non-typhoidal salmonella bacteraemia as compared with typhoid fever was significantly more common in HIV infected patients than in non-HIV infected patients (p < 0.01). It was also a cause of bacteraemia in patients with other immuno-suppressive conditions and in some patients without identifiable risk factors.
