Résumé
House shrews (Suncus murinus) and rats (Rattus rattus diardii), trapped during a survey period from July 1978 to December 1979 and thereafter on a random basis, from residences within and outside the Veterinary Research Institute, Ipoh, Malaysia campus, were bacteriologically examined for the presence of salmonellae. Of the 55 shrews and 8 rats examined, 39 (71%) shrews and 2 (25%) rats were found positive. There were 46 Salmonella isolates which included 5 dual infections. These were serotyped as S. weltevreden, S. bareilly, S. stanley, S. augustenborg, S. hvittingfoss, S. emek, S. paratyphi B, S. ohio and S. matopeni in order of frequency of isolation. The significance of these findings especially with regard to salmonellosis in man and animals is discussed.

Cardiac complications are the leading cause of death in patients with the thalassaemia syndromes. The cardiac abnormalities may be the result of chronic anaemia or iron overload. The cardiac status was evaluated in 30 patients with thalassaemia to determine whether the structural and functional changes could be related to the degree of anaemia or to other factors suggesting iron overload. Clinical, radiological, electrocardiographic and echocardiographic methods were employed. The study provided evidence that cardiac abnormalities were due to undertransfusion. Echocardiography provides a reliable, noninvasive means of assessing cardiac abnormalities in patients with thalassaemia.
