  • Tritrichomonas species (IMC strain) were isolated from a patient with cholecystitis linked to agammaglobulinemia, with genetic analyses confirming it as T. foetus (cattle/swine genotype).

The AUD of the four carbapenems, imipenem (IPM/CS), panipenem (PAPM/BP), meropenem (MEPM), and biapenem (BIPM), was examined at three hospitals in Ibaraki Prefecture, between April and September 2004.
