A case-control study was performed in South Australia to determine if L. longbeachae infection was associated with recent handling of commercial potting mix and to examine possible modes of transmission. Twenty-five laboratory-confirmed cases and 75 matched controls were enrolled between April 1997 and March 1999. Information on underlying illness, smoking,(More)
In 2000, the OzFoodNet network was established to enhance surveillance of foodborne diseases across Australia. OzFoodNet consists of 7 sites and covers 68 per cent of Australia's population. During 2001, sites reported 15,815 cases of campylobacteriosis, 6,607 cases of salmonellosis, 326 cases of shigellosis, 71 cases of yersiniosis, 61 cases of(More)
In December 2004, the Department of Human Services investigated an outbreak of Q fever in South Australia. A case-control study tested an association between attending a local saleyard and human illness. A case was defined as a person with clinical illness and evidence of seroconversion or high phase II IgM. Controls were selected from a database of(More)
An outbreak of an unusual tetracycline-sensitive, rifampicin- and ciprofloxacin-resistant, methicillin-resistant Staphylococcus aureus (MRSA) strain at a large teaching hospital was investigated. Two typing methods, phage typing and restriction fragment length polymorphism (RFLP) by pulsed-field gel electrophoresis (RFLP-PFGE), gave conflicting results(More)
The evolution over 30 years of a population of methicillin-resistant Staphylococcus aureus (MRSA) from a tertiary referral hospital was studied by phylogenetic analysis of SmaI-generated restriction fragment length polymorphisms (RFLPs). The results suggest that a new clone of MRSA appeared at the hospital in the early 1980s, which, although usually(More)
In this study, the phenotypic and genotypic characteristics of 50 methicillin-resistant Staphylococcus aureus (MRSA) isolates (43 contemporary and 7 archaic strains from the mid-1960s) from four Sydney hospitals in the central Sydney area were compared. Phenotypic analysis based on antibiotic profiles and phage typing patterns categorized the MRSA isolates(More)
Methicillin-resistant Staphylococcus aureus (MRSA) infection in a cystic fibrosis (CF) unit was investigated. Two typing methods, phage-typing and restriction fragment length polymorphism (RFLP) by pulsed-field gel electrophoresis (PFGE) and phylogenetic analysis, showed that nonsocomial transmission of MRSA from the general hospital population had(More)
In this study, an outbreak of Campylobacter jejuni gastroenteritis occurring at a boarding school was investigated using a retrospective cohort study and environmental health investigation. Thirty-five cases of gastroenteritis were recorded among 58 questionnaire respondents, with 14 of 18 persons submitting fecal samples having confirmed C. jejuni(More)
Exposure to Coxiella burnetii is a risk in the Hunter New England (HNE) region of New South Wales (NSW), Australia, based on yearly reported cases of Q fever. We assessed seroprevalence of phase II antibodies to C. burnetii by indirect immunofluorescence assay (IFA; screening at 1/50 dilution) of residents of 24 local government areas (LGA) of the HNE(More)
This report investigates an outbreak of acute gastrointestinal illness, microbiologically and epidemiologically linked to an aged-care facility and seeks to determine if there was a point source of infection. A register of cases that included onset date and time of illness and symptoms was maintained by nursing staff. Faecal specimens were tested for(More)
