| persistent viral infection. the carrier state. | a persistent viral infection is one in which the virus in a replicating or non-replicating form persists in the host beyond the normal recovery and elimination period for that particular viral infection. the clinical significance and mechanisms of persistence, when known, are discussed for the important viral infections of dogs and cats. particular emphasis is given to feline viral rhinotracheitis, feline calicivirus, canine distemper, and feline leukemia. | 1986 | 3097907 |
| genetic analysis of the rna polymerase gene of caliciviruses from dogs and cats. | caliciviruses that infect animals including humans cause a specific disease syndrome in their respective hosts. feline calicivirus (fcv) is a major pathogen of respiratory disease of cats, and human caliciviru is a causative agent of diarrhea. it has been suggested, furthermore, that fcv and newly recognized canine calicivirus (cacv) may also be possible causes of diarrhea in these animal species. in this study nucleotide sequence of the rna polymerase gene of two caliciviruses of canine origin, ... | 1999 | 10423680 |
| expression and processing of the canine calicivirus capsid precursor. | the orf2 product of canine calicivirus (cacv) was identified and its processing in mammalian cells was analysed. immunoblot analysis revealed the presence of the 75 kda capsid precursor in addition to a 57 kda capsid protein and a 22 kda n-terminal polypeptide in cacv-infected cells treated at an elevated temperature. when the cacv orf2 was expressed in a transient mammalian expression system, only the 75 kda precursor was detected in immunoblot analysis, suggesting that no post-translational pr ... | 2000 | 10640558 |
| serologic survey of selected viral agents in recently captured wild north american river otters (lontra canadensis). | blood samples were collected from 64 wild north american river otters (lontra [lutra] canadensis) from northern and eastern new york state and analyzed for serologic evidence of exposure to selected viral agents during a 1995 1996 translocation program. no clinical signs of disease nor lesions suggestive of prior viral exposure were seen. titers were detected for antibodies against canine distemper virus, canine herpesvirus-1, and canine parvovirus-2 but not for antibodies against canine adenovi ... | 2000 | 10982127 |
| serosurvey of viral infections in free-ranging namibian cheetahs (acinonyx jubatus). | cheetahs (acinonyx jubatus) in captivity have unusually high morbidity and mortality from infectious diseases, a trait that could be an outcome of population homogeneity or the immunomodulating effects of chronic stress. free-ranging namibian cheetahs share ancestry with captive cheetahs, but their susceptibility to infectious diseases has not been investigated. the largest remaining population of free-ranging cheetahs resides on namibian farmlands, where they share habitat with domestic dogs an ... | 2004 | 15137485 |
| duration of immunity for canine and feline vaccines: a review. | in our studies aimed at assessing the minimum duration of vaccinal immunity (doi), approximately 1000 dogs have been vaccinated with products from all the major us veterinary biological companies. the doi for the various products is determined by antibody titers for all dogs and, by challenge studies in selected groups of dogs. recently, all major companies that make canine vaccines for the u.s. market have completed their own studies; published data show a 3 years or longer minimum doi for the ... | 2006 | 16707236 |
