| kunjin virus: an australian variant of west nile? | kunjin (kun) is a flavivirus in the japanese encephalitis antigenic complex that was first isolated from culex annulirostris mosquitoes captured in northern australia in 1960. it is the etiological agent of a human disease characterized by febrile illness with rash or mild encephalitis and, occasionally, of a neurological disease in horses. kun virus shares a similar epidemiology and ecology with the closely related murray valley encephalitis (mve) virus, the major causative agent of arboviral e ... | 2001 | 11797773 |
| the relationships between west nile and kunjin viruses. | until recently, west nile (wn) and kunjin (kun) viruses were classified as distinct types in the flavivirus genus. however, genetic and antigenic studies on isolates of these two viruses indicate that the relationship between them is more complex. to better define this relationship, we performed sequence analyses on 32 isolates of kun virus and 28 isolates of wn virus from different geographic areas, including a wn isolate from the recent outbreak in new york. sequence comparisons showed that th ... | 2001 | 11585535 |
| early diagnosis of murray valley encephalitis by reverse transcriptase-polymerase chain reaction. | a 4-year-old aboriginal boy developed encephalitis due to murray valley encephalitis virus (mve) following an earlier infection with kunjin virus (kun). the illness was severe, resulting in cerebral atrophy and profound physical and intellectual disability. the earlier kun infection complicated his serological profile and delayed antibody responses to mve. by contrast, the reverse transcriptase-polymerase chain reaction (rt-pcr) assay detected mve in serum 3 days after the onset of illness and 4 ... | 2000 | 10740807 |
| a presumptive case of fatal murray valley encephalitis acquired in alice springs. | a presumptive case of murray valley encephalitis (mve) acquired in alice springs in march 1997 is reported. the patient subsequently died in mackay. the diagnosis of murray valley encephalitis was supported by the detection of flavivirus igm in cerebrospinal fluid. low titres of igm specific to murray valley encephalitis and alfuy were detected in a single serum sample. the patient's travel movements indicate that his infection was acquired in the alice springs vicinity. this conclusion was furt ... | 1998 | 9648367 |
