Molecular and epidemiological features of norovirus-associated gastroenteritis outbreaks in Victoria, Australia in 2001John A Marshall
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria, Australia
J Med Virol 75:321-31. 2005..Norovirus was occasionally detected by EM but not by RT-PCR. The occurrence of norovirus outbreaks is modulated by a large group of factors, which will have to be considered in any epidemiological model...- Laboratory diagnosis of norovirusJohn A Marshall
Victorian Infectious Diseases Reference Laboratory, Melbourne, Australia
Clin Lab 52:571-81. 2006.... - High level excretion of Norwalk-like virus following resolution of clinical illnessJ A Marshall
Victorian Infectious Diseases Reference Laboratory, Carlton South, Australia
Pathology 33:50-2. 2001..This indicated that the NLV belonged to genogroup 2 and was more closely related to the Camberwell subgroup, the most common circulating in southeast Australia at present, than to the Norwalk and Mexico viruses... - Incidence and characteristics of endemic Norwalk-like virus-associated gastroenteritisJohn A Marshall
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria, Australia
J Med Virol 69:568-78. 2003..NLV G1 seasonality was significantly different from that of NLV G2. Seven major NLV clusters were identified by phylogenetic analysis... - Rotavirus detection and characterisation in outbreaks of gastroenteritis in aged-care facilitiesJohn Marshall
Victorian Infectious Diseases Reference Laboratory, 10 Wreckyn Street, North Melbourne, Vic 3051, Australia
J Clin Virol 28:331-40. 2003..Although rotavirus is a major cause of gastroenteritis in children, its role in adult gastroenteritis and the sensitivity of different methods for its detection in specimens collected from adults are less well understood... - Failure to detect norovirus in a large group of asymptomatic individualsJ A Marshall
Victorian Infectious Diseases Reference Laboratory, Locked Bag 815, Carlton South, Victoria 3053, Australia
Public Health 118:230-3. 2004..8%. Thus, it is unlikely that asymptomatic people are an important reservoir for norovirus... - Molecular features of astrovirus associated with a gastroenteritis outbreak in an aged-care centreJ A Marshall
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria, Australia
Eur J Clin Microbiol Infect Dis 26:67-71. 2007..The findings, taken together with previous work, indicate the AsV serotype most commonly associated with gastroenteritis outbreaks among the elderly is serotype 1 AsV... 
Molecular changes associated with altered patterns of norovirus outbreak epidemics in Victoria, Australia, in 2006 to 2007Leesa D Bruggink
Gastroenteritis Section, Victorian Infectious Diseases Reference Laboratory, 10 Wreckyn Street, North Melbourne, Victoria 3051, Australia
J Clin Microbiol 48:857-61. 2010..4 variants within a short space of time, resulting in two outbreak epidemics in a short space of time, i.e., in the 1 year. This study provides a potentially greater ability to predict the characteristics of NoV epidemics...
Molecular and epidemiological features of gastroenteritis outbreaks involving genogroup I norovirus in Victoria, Australia, 2002-2010Leesa D Bruggink
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria, Australia
J Med Virol 84:1437-48. 2012..GI.2/GI.2, GI.2/GI.6, and GI.4/GI.4 strains tended to undergo periodic shifts in nucleotide sequence whereas various GI.3b/GI.3 strains tended to circulate simultaneously...- Evaluation of the Dako IDEIA norovirus EIA assay for detection of norovirus using faecal specimens from Australian gastroenteritis outbreaksAnna Dimitriadis
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria, Australia
Pathology 38:157-65. 2006..Since visual analysis can be used for result assessment almost as reliably as photometric analysis, the test kit would be useful for laboratories lacking specialist equipment such as a photometric microplate reader... - Evaluation of the RIDA(®)QUICK immunochromatographic norovirus detection assay using specimens from Australian gastroenteritis incidentsLeesa D Bruggink
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria 3051, Australia
J Virol Methods 173:121-6. 2011..Genotypes not detected included GI.4 and GI.6. The assay was simple and quick to perform. It is valuable in a point-of-care situation or as a backup in a laboratory where a rapid initial norovirus result is required... - The incidence of norovirus-associated gastroenteritis outbreaks in Victoria, Australia (2002-2007) and their relationship with rainfallLeesa D Bruggink
Victorian Infectious Diseases Reference Laboratory, North Melbourne, Victoria, Australia
Int J Environ Res Public Health 7:2822-7. 2010..In an era where there is concern about the potential effects of global warming on weather patterns, it should be borne in mind that future changes in NAGO incidence may reflect altered world weather patterns... - The dynamics of norovirus outbreak epidemics: recent insightsJohn A Marshall
Victorian Infectious Diseases Reference Laboratory, 10 Wreckyn Street, North Melbourne, Victoria 3051, Australia
Int J Environ Res Public Health 8:1141-9. 2011.... - The effect of fecal turbidity on norovirus detection by reverse transcriptase polymerase chain reactionKristie J Witlox

Diagn Microbiol Infect Dis 66:230-2. 2010..Feces processed so that particle size does not exceed approximately 560 nm do not display greater norovirus RT-PCR inhibitory effects than those that have undergone greater purification... - An outbreak of shigellosis in a child care centreDania Genobile
Communicable Diseases Section, Department of Human Services, Melbourne, Victoria
Commun Dis Intell 28:225-9. 2004.... - Molecular changes in the norovirus polymerase gene and their association with incidence of GII.4 norovirus-associated gastroenteritis outbreaks in Victoria, Australia, 2001-2005Leesa Bruggink
Victorian Infectious Diseases Reference Laboratory, 10 Wreckyn St, North Melbourne, Victoria, 3051, Australia
Arch Virol 153:729-32. 2008..The pv in a non-epidemic year (2003, 2005) was the same as in the preceding year (AATCTG in 2002 and 2003, AACTTG in 2004 and 2005). Thus, specific short nucleotide sequences could act as markers of major GII.4 norovirus epidemics... - The A-rich RNA sequences of HIV-1 pol are important for the synthesis of viral cDNACameron P Keating
