ABSTRACT
Between January and December 1987, gentamicin-methicillin-resistant strains of Staphylococcus aureus (GMRSA) were isolated from 7 patients in a male surgical ward at Rajavithi General Hospital. Six patients developed significant infection which included sepsis (2), pneumonia (1), infection in the eye, ear and wound (1), wound infection (2), and one patient had GMRSA isolated from his sputum. The strains were untypable with standard phage type and were resistant to methicillin, gentamicin, amikacin, kanamycin, streptomycin, tetracycline, erythromycin and chloramphenicol, but susceptible o vancomycin and cotrimoxazole. GMRSA were also isolated from bed-rail and the used rubber gloves left in the affected room. The GMRSA strains contained 5 plasmids of molecular weight of 18, 11, 2, 1.8 and 1.7 Md. The 2Md plasmid coded for chloramphenicol resistance and the 1.8 Md plasmid for erythromycin resistance.

The microbiological quality of 4 feed ingredients and 29 hospital-prepared non-sterile enteral feeds were determined. All 4 feed ingredients yielded no growth of micro-organisms, but all 29 enteral feeds had aerobic viable counts exceeding 10(5) organisms g-1 with a high coliform count in each feed. Both the aerobic palte count and the coliform count exceeded numerical limits for micro-organisms in enteral feeds. Sources of contamination were the feed containers and the liquidizer which were inadequately disinfected.
