The molecular epidemiology of the infectious disease caused by feline calcivirus (FCV) in Japan was investigated by analysing the phylogenetic relationship among 21 Japanese field isolates, including the F4 strain, and 30 global isolates. Parts of the capsid gene (B–F) of the isolates were amplified by RT-PCR, and the amino acid sequences were compared with(More)
We analysed genogroups of four feline calcivirus (FCV) isolates (FCV-S, H10, Ao198-1 and ML89) obtained from cats that experienced FCV infection after having been vaccinated against FCV. New PCR primer sets (8F/8R, Ao-S/Ao-A, cp-S/cp-A) were also designed, since the conventional Seal primer failed to amplify the target sequences in two samples. The(More)
Estimating the cost of hospital infection has become a matter of increasing interest in terms of health economics. This study aimed to assess the accuracy of economic studies on hospital infections, using surgical site infection (SSI) as an example. A search was performed for original articles reporting the cost of SSI, published in the English language(More)
Although prevention of feline calcivirus (FCV) infection by vaccination has been attempted, and isolation of FCV, development of the disease, and a few fatal cases in vaccinated cats have been reported. Fifteen FCV strains isolated from cats that had been vaccinated with commercially available FCV vaccines (F9, FCV-255, and FC-7) were genogrouped. Molecular(More)
We investigated primitively the molecular basis of the neural spread of a feline calcivirus isolate (FCV-S) from the spinal cord of a cat that died after manifesting excitation. Experimental infections of cats with three clones from parent virus isolate FCV-S, isolated based on plaque size, were performed, and virus recovery from the spinal cord and the(More)
Elderly subjects with mild memory impairment but not apparent dementia are the focus of early intervention trials. To examine the effects of structural psychosocial intervention for elderly subjects with very mild Alzheimer disease, i.e., Clinical Dementia Rating 0.5. The design is a prospective study. The experimental group (14 Clinical Dementia Rating 0.5(More)
Feline calicivirus (FCV) is a pathogenic microorganism that causes upper respiratory diseases in cats. Recently, an FCV infection with a high mortality rate has been confirmed, and there is need to develop a treatment for cases of acute infection. We evaluated whether the replication of FCV could be prevented by RNA interference. For this study, we(More)
Feline calicivirus cause feline respiratory diseases, and inactivated and attenuated vaccines are available for its prevention. Moreover, the presence of vaccine breakdown strains (VBS) is problematic. In Japan, feline recombinant interferon (rFeIFN) has been used for its treatment. However the method of compare with each strains has not established. To(More)
Commercially available vaccines have been used widely to prevent feline calicivirus infection (FCI). However, with their widespread use, field strains, which are weakly cross-reactive with the live-virus vaccine strain F9, have posed the problem of vaccine breakdown. Recently the existence of FCV—associated virulent systemic disease (VSD) has been(More)
