| recovery of viruses and bacteria in waters off bondi beach: a pilot study. | a pilot study was conducted between february and april, 1989, on the occurrence of sewage-derived viruses and bacteria in the beach and nearshore waters off bondi, sydney. enteroviruses were isolated from 41% of a total of 66 sewage, sea-water, grease and sediment samples. poliovirus vaccine strains accounted for 78% of the isolates. adenoviruses were isolated four times and coxsackievirus b was isolated twice in samples that were collected away from the bathing area. rotavirus and hepatitis a v ... | 1989 | 2556634 |
| comparison of the abundance of the fecal sterol coprostanol and fecal bacterial groups in inner-shelf waters and sediments near sydney, australia. | concurrent measurement of the sewage tracer coprostanol and fecal indicator bacteria were made for water and sediments collected in january 1992 from coastal waters off sydney, australia. the coprostanol results were compared with data from an earlier survey conducted in 1989 before the commisioning of sydney's deepwater ocean outfalls in 1990 and 1991. good correlations were observed for both water and sediment samples between coprostanol and the two fecal indicator organisms, fecal coliforms a ... | 1993 | 8360300 |
| clostridium perfringens food-borne outbreak: an epidemiological investigation. | on 3 april 1994, the western sector public health unit was notified of an outbreak of gastroenteritis at a christian youth camp. attending the camp were 820 people; 241 (42 per cent) of 574 camp participants who completed a questionnaire reported illness. of these, 230 met the case definition. main symptoms reported were stomach cramps (78 per cent), diarrhoea (67 per cent) and nausea (46 per cent). bacterial analysis of leftover chicken grew 2.3 x 10(7) and 3.3 x 10(7) colonies/g of clostridium ... | 1996 | 8799084 |
| evaluation of the cleaning and disinfection efficacy of the deko-190; award-based automated washer/disinfector. | the deko-190 washer-disinfector combines both automatic washing and thermal disinfection functions and is designed for the decontamination of ward utensils (such as bedpans and urine bottles) and instruments used in minor surgery prior to sterilization. we undertook a microbiological evaluation of the disinfection efficacy of the machine, using its short wash plus disinfection programme and sealed suspensions of test organisms placed at various points within the instrument. suspensions of entero ... | 2000 | 11023723 |
| concentrations of pathogens and indicators in animal feces in the sydney watershed. | a fecal analysis survey was undertaken to quantify animal inputs of pathogenic and indicator microorganisms in the temperate watersheds of sydney, australia. the feces from a range of domestic animals and wildlife were analyzed for the indicator bacteria fecal coliforms and clostridium perfringens spores, the pathogenic protozoa cryptosporidium and giardia, and the enteric viruses adenovirus, enterovirus, and reovirus. pathogen and fecal indicator concentrations were generally higher in domestic ... | 2005 | 16204506 |
| microbial exposure assessment of an urban recreational lake: a case study of the application of new risk-based guidelines. | new who and australian guidelines promote a risk-management approach for minimising exposure to pathogens in recreational waters. between 2003 and 2005, they were applied to lake parramatta (10 ha, 450 ml), a potential recreation site in sydney, australia. a three stage approach was developed involving (1) initial suitability assessment using historic data, (2) revised suitability assessment based on new data and (3) characterisation of hazardous (especially wet weather) events. contrary to the ... | 2006 | 17037160 |
