To investigate the prevalence of bovine papillomavirus (BPV) in bovine papilloma and healthy skin, DNA extracted from teat papillomas and healthy teat skin swabs was analysed by PCR using the primer pairs FAP59/FAP64 and MY09/MY11. Papillomavirus (PV) DNA was detected in all 15 papilloma specimens using FAP59/FAP64 and in 8 of the 15 papilloma specimens(More)
Surveillance for scrub typhus was conducted in Japan in 1998 using a questionnaire. A total of 462 cases were reported. Scrub typhus occurred in both the fall and spring in the northern part of Honshu (the main island), and in the fall in the central part of Honshu and on the island of Kyushu. The occurrence of the disease varied with age, gender, and(More)
Noroviruses (NVs) are common pathogens that consist of genetically divergent viruses that induce gastroenteritis in humans and animals. Between September 1999 and June 2004, 1,898 samples obtained from patients showing sporadic or outbreak gastroenteritis in Chiba Prefecture, Japan, were tested for NVs by reverse transcription-PCR. NVs were detected in 603(More)
OBJECTIVES To identify different rickettsial infections using a specific immunofluorescent technique in patients clinically diagnosed as 'typhus fever' in the Central Province of Sri Lanka, and to define the clinical picture, assess the severity of infection and to determine the pattern of geographical distribution of the infections of the hospital-based(More)
Sapporo-like viruses (SLV) are a causative agent of gastroenteritis in humans. SLV-specific primers were newly designed in capsid protein-coding region and 529 fecal samples collected from gastroenteritis patients were tested. Thirty-five samples (6.6%) were found to be positive by reverse transcriptase-polymerase chain reaction (RT-PCR). Out of 35 positive(More)
Two G12 human rotavirus strains, CP727 and CP1030, were isolated from the respective diarrheic stools of an infant and an adult in Japan. VP7 gene sequences of strains CP727 and CP1030 showed high identity with that of the G12 prototype strain L26, and with those of G12 strains reported recently from Thailand, the United States, and India. VP4 gene(More)
Infectivity of adenovirus type 5 (Ad5) to cells depends primarily on its fiber-mediated binding to the coxsackievirus and adenovirus receptor (CAR) on target cells. Down-regulated CAR expression, often found in human tumors, hampered Ad5-mediated gene transfer. Ad 11 and Ad 35, belonging to a subtype B group, use CD46 as their cellular receptors;(More)
Primer pairs for PCR were designed from the gene encoding the 17,000-molecular-weight genus-common antigen of Rickettsia japonica, Rickettsia rickettsii, Rickettsia conorii, Rickettsia typhi and Rickettsia prowazekii. Primers R1, R2 were designed for amplifying the genomic DNA from spotted fever group (SFG) rickettsiae and epidemic typhus rickettsiae.(More)
Polymerase chain reaction (PCR) with nested primer pairs was used to diagnose Tsutsugamushi disease and identify the Rickettsia tsutsugamushi serotype. The primer pairs used for PCR were designed on the basis of the nucleotide sequence of the gene that encodes the 56-kDa antigen. Five serovariants, the Gilliam, Karp, Kato, Kawasaki, and Kuroki strains of(More)
Sapovirus (SV), which causes gastroenteritis in humans, is composed of genetically divergent viruses classified into 5 genogroups. In this study, 2.2-kb nucleotide sequences of the 3′ terminus of the genome of 15 SV strains detected in Japan were determined. The 15 SV strains could be classified into four genogroups (GI, GII, GIV and GV), and in two of(More)
