Over a 12-month period, 74 isolates of Serratia marcescens
were obtained from various sources at Tygerberg
Hospital. The majority of these isolates were from
catheterized patients with urinary tract infections, and were
non-pigmented and resistant to all antibiotics tested, excepting
amikacin and neomycin. All isolates transferred
resistance to tobramycin, gentamicin and tetracycline by
conjugation to Escherichia coli recipients as separate
markers at low frequency. A non-self-transmissible plasmid
conferring resistance to kanamycin, ampicillin and
gentamicin was mobilized from Serratia species to E.
coli, and became fully self-transmissible in subsequent
matings.
