We have reported the antimicrobial susceptibility of clinical isolates of @entity526 in 1983 and 1984 to 4 antibiotics, @entity869 (ABPC), @entity7048 ( @entity12706 ), @entity33910 ( @entity11984 ) and @entity801 (GM), in the previous report. In this paper, we described the antimicrobial susceptibility of @entity4005 sp. to the same antibiotics during the same period reported for @entity526 before. Numbers of isolates tested were 1,671 strains in 1983 and 1,374 strains in 1984. We determined MICs of the 4 antibiotics against isolates by the standard method of the Japan Society of Chemotherapy. The most effective agent was GM among the 4 antibiotics. @entity11984 had a similar antimicrobial activity to GM. Resistance rates were low for both agents. CEZ had a fairly good antimicrobial activity, but it was less active than GM and @entity11984 . ABPC was not effective. There was neither significant annual change of antimicrobial activity of each agent against isolates nor an increasing tendency of resistant strains in the last 5 years. Depending on isolates from clinical materials, differences in the susceptibility were noted and there was a high ratio of resistant organisms among isolates from urine.
