Résumé
The current drugs recommended for treatment of melioidosis are tetracycline, chloramphenicol and cotrimoxazole. Unfortunately these drugs are not the drug of choice in an acutely ill patient with septicaemia prior to the availability of laboratory results. With the discovery of the new cephalosporins which have a broad spectrum of activity clinicians are using them either alone or in combination with other antibiotics in such critical situations. Hence, an in-vitro study was carried out on the susceptibility of 41 strains of P. pseudomallei isolated in Malaysia, to these new cephalosporins and a new quinolone. The results showed that all the cephalosporins tested had some activity on the strains tested, with ceftazidime being the most active drug. Pefloxacin had very poor activity. However, further clinical studies are required to determine the duration, dosage and in-vivo activity of the antibiotics.

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.
