Molecular confirmation of transmission route of Staphylococcus intermedius in mastoid cavity infection from dog saliva.

We report a case of infection of a mastoid cavity after mastoidectomy had been performed for chronic otitis media with cholesteatoma. The infection was caused by Staphylococcus intermedius after a pet dog had licked the patient's ears. Bacterial strains from the dog's saliva and the otorrhea in the patient were confirmed to be identical by pulsed-field gel electrophoresis analysis.

Evaluation of dot-ELISA for serological diagnosis of amebiasis.

We improved the dot enzyme-linked immunosorbent assay (dot-ELISA) reported by Itoh and Sato, and assessed the usefulness of this test for the diagnosis of amebiasis. The sensitivity of dot-ELISA was compared with that of plate ELISA, the indirect hemagglutination test (IHA), and the indirect fluorescent antibody test (IFA) for the diagnosis of amebiasis. Of 37 serum samples from patients with documented amebiasis, 36 (97.

[Severe falciparum malaria with prolonged hemolytic anemia after successful treatment with intravenous artesunate].

We report a 68-year-old woman with severe falciparum malaria contracted in Tanzania. She presented high parasitemia and was treated successfully with intravenous artesunate, a qinghaosu derivative, and aggressive supportive therapy. She developed hemolytic anemia and jaundice on day 11 and blood transfusion was required.

[Hospital outbreak of viral gastroenteritis attributed to Norwalk-like viruses in Japan].

Background: Norwalk-like viruses (NLVs), RNA viruses in the family of Caliciviridae, are known as a pathogen of nonbacterial food-borne gastroenteritis associated with eating raw oysters. NLV can spread from person to person with strong infectivity and can cause large epidemics in communities, schools, nursing homes, and hospitals. Here, we describe an outbreak of gastroenteritis associated with NLVs, possibly introduced from outside the hospital, in four different wards on four different occasions between November 1999 and April 2000, in a university affiliated hospital in Tokyo.
