Neisseria gonorrhoeae strains with reduced susceptibility to cefixime (MICs, 0.25 to 0.5 micro g/ml) were isolated from male urethritis patients in Tokyo, Japan, in 2000 and 2001. The resistance to cephems including cefixime and penicillin was transferred to a susceptible recipient, N. gonorrhoeae ATCC 19424, by transformation of the penicillin-binding(More)
Neisseria gonorrhoeae strains with reduced susceptibility to cefixime and ceftriaxone, with minimum inhibitory concentrations (MICs) of cefixime of 0.125-0.25 microg/ml and ceftriaxone of 0.031-0.125 microg/ml, were isolated from male urethritis patients in Tokyo, Japan, in 2006. The amino acid sequences of PenA, penicillin-binding protein 2, in these(More)
We report a case of meningococcemia without meningitis, which is a rare infectious disease in Japan. A 32-year-old woman was referred to our hospital with fever and joint pain. Her clinical presentation and the results of laboratory examination on admission suggested viral infection. However, her condition rapidly progressed to septic shock with fulminans(More)
Rhodococcus equi, a bacterium present in soil, is a common cause of pneumonia in foals. This organism has been recognized as an opportunistic pathogen in humans, typically causing infection in immunocompromised hosts such as HIV-infected patients and organ transplant recipients. However, human infection with R. equi has not been reported in Japan except in(More)
For the purpose of nationwide surveillance of antimicrobial susceptibility of bacterial respiratory pathogens from patients in Japan, the Japanese Society of Chemotherapy (JSC) started a survey in 2006. From 2009, JSC continued the survey in collaboration with the Japanese Association for Infectious Diseases and the Japanese Society for Clinical(More)

According to the results of the fixed-point survey, the incidence of both genital chlamydial infection and gonococcal infection has tended to decrease since 2003 in Japan. This trend has been more marked in young persons of both sexes. However, it has been suggested that the fixed-point survey has a problem with respect to the method of selecting designated(More)
We investigated the enhancement of the antimicrobial activities of beta-lactams against cefixime (CFIX)-resistant Neisseria gonorrhoeae in the presence of macrolides. Ten strains of CFIX-resistant N. gonorrhoeae, isolated between 2000 and 2003 from male patients with urethritis at Jikei University Affiliated Hospital and its related clinics in the Tokyo(More)
We report a patient with gnathostomiasis in whom a specific diagnosis of Gnathostoma spinigerum infestation was made morphologically upon removal of the worm. A 47-Year-old Japanese male on a business trip to Vietnam ate fried frog with a Vietnamese friend in January 2002, the friend was diagnosed with gnathostomiasis in June 2002. The patient noted(More)
