In August 2009, the Centers for Disease Control and Infection (CDC) began a multistate outbreak investigation to determine the source of the infections. This report summarizes the results of this ongoing investigation, which, as of 30 Dec 2009, had identified 85 _S._ Typhimurium human isolates with the outbreak strain from 31 states”.

Results of the investigation will be used to better inform biosecurity messages to the public and the poultry industry and improve knowledge of the epidemiology of this particular phage type in Tasmania. Laboratory costs of this work are funded by the Wildlife Event Investigations Team program managed by Animal Health Australia.” http://www.animalhealthaustralia.com.au/fms/Animal%20Health%20Australia/ADSP/AHSQ/AHSQ%20Q3%202009.pdf Follow link or see Standing Items below for more informat T Grillo 06/10/2009 06/10/2009 Update from Tasmania DPIPWE: Significant sparrow mortality in the greater Hobart area has been under investigation by DPIPWE (Department of Primary Industries, Parks, Water and Environment) since July. So far 11 x sparrows (Passer domesticus), 1x Wattlebird (Anthochaera paradoxa) and 1x Silver eye (Zosterops lateralis) have been submitted to the Animal Health Laboratory (AHL), Launceston after being found dead (n=12) or moribund (n=1). This includes a sparrow submitted in June by a private practitioner. Avian influenza was ruled out by PCR at AHL in all but one case where the sample submitted was not suitable. Bacterial isolates were identified in-house and Salmonella serotyping was performed at Microbiological Diagnostic Unit (MDU), Melbourne. Samples from a number of suitable cases were also sent to Australian Animal Health Laboratories, CSIRO, Geelong for Newcastle’s Disease rule out. All were negative by PCR analysis. Pathology findings (gross and histological) were consis Tiggy Grillo 21/09/2009 21/09/2009 USGS reported on recent outbreaks of avian salmonellosis (Salmonella typhimurium) in wild birds across several states of the USA. People across the country have reported finding dead or distressed wild birds (a range of species) near their homes and bird feeders. No evidence exists that the strains found in dead wild birds this year are the same strains of Salmonella that prompted the recalls in peanuts, pistachios, or wild bird seed. Large-scale mortalities of passerines using feeding stations are common across the United States and often occur during times of increased supplemental feeding, such as winter and spring. Many species also act as carriers without any clinical signs.

We tested the households of a series of people with salmonellosis in urban Darwin. This case series revealed Salmonella species in 7 household samples out of 10. Of the animal species tested, we found S. Ball in green tree frog faeces and dog faeces; S. Urbana in green tree frog faeces, S. Anatum in gecko faeces and S. Virginia in snake faeces. Rick Speare 05/10/2005 PS. We have an overview of the English literature on salmonellas in amphibians available on line in the files at http://www.jcu.edu.au/school/phtm/PHTM/frogs/otherdiseases-bacteria.htm If you do undertake surveys of frogs in NT, make sure your host taxonomy is accurate. Rick Speare 05/10/2005 I am not aware of any comprehensive survey for salmonellas in native Australian frogs. You would be aware I suppose of our survey of salmonellas in cane toads (O'Shea, P., Speare, R. and Thomas, A.D. Salmonellas from the cane toad, Bufo marinus. Australian Veterinary Journal 1990;67:310.), the summary of salmonellas from wildlife in North Qld (Thomas AD, Forbes-Faulkner JC, Speare R, Murray C. Salmonellosis in wildlife from Queensland. Journal of Wildlife Diseases 2001;37:229-238.) and the paper that implicated frogs as potentially contaminating rainwater tanks in central Queensland (Taylor R, Sloan D, Cooper T, Morton B, Hunter I. A waterborne outbreak of Salmonella Saintpaul. Communicable Diseases Intelligence 2000;24(11):336-340.). The latter paper also reported the only isolation of Salmonella from a frog in the NSSS database - S. Onderstepoort from a green tree frog(scientific name not given). Shellee Williams 05/10/2005 Shellee Williams is investigating causes of cases of a particular Salmonella subtype in and around Darwin. She is presently planning an analytical study (case-control) and requires further information about salmonella subtypes(especially S.bell) carried by frog species common to the Darwin area. If you can help, or have information about amphibian species distributions and the varieties of Salmonella subtypes known to be carried by wildlife in the area please contact Shellee direct.
