Research – Multistate Outbreak of Salmonella enterica Serovar Heidelberg with Unidentified Source, Australia, 2018–2019

Posted on December 29, 2021 by | Leave a comment

CDC

Abstract

We report a multistate Salmonella enterica serovar Heidelberg outbreak in Australia during 2018–2019. Laboratory investigation of cases reported across 5 jurisdictions over a 7-month period could not identify a source of infection but detected indicators of severity and invasiveness. The hospitalization rate of 36% suggested a moderately severe clinical picture.

Salmonella enterica serovar Heidelberg is a frequently identified serotype among infections in humans in North America, East Africa, and Asia but is uncommon in Australia. An average of 37 cases of Salmonella Heidelberg were notified in Australia annually in 2009–2017, predominantly overseas acquired (1). Six outbreaks have been reported nationally since 1995; 1 outbreak in 1996 had >500 cases, but most have <7 cases (R. Bell, pers. comm. [email], 2020 Jun 16). We report a national outbreak of Salmonella Heidelberg infection across 5 jurisdictions over 7 months.

We report a national outbreak investigation of a locally uncommon S. enterica serovar of unknown origins in Australia. Although Salmonella Heidelberg outbreaks are relatively uncommon in Australia, given this outbreak’s comparatively high hospitalization rate and the presence of saf fimbrial genes in the implicated strain, future cases warrant prompt investigation to assess severity and invasiveness. A platform for real-time exchange of sequence data in Australia and use of routine WGS for salmonellosis cases, including comparison with local and international strain data, may enable more timely detection of outbreaks.

Research – Detrimental Effect of Ozone on Pathogenic Bacteria

Posted on December 27, 2021 by | Leave a comment

MDPI

Background: Disinfection of medical devices designed for clinical use associated or not with the growing area of tissue engineering is an urgent need. However, traditional disinfection methods are not always suitable for some biomaterials, especially those sensitive to chemical, thermal, or radiation. Therefore, the objective of this study was to evaluate the minimal concentration of ozone gas (O3) necessary to control and kill a set of sensitive or multi-resistant Gram-positive and Gram-negative bacteria. The cell viability, membrane permeability, and the levels of reactive intracellular oxygen (ROS) species were also investigated;

Material and Methods: Four standard strains and a clinical MDR strain were exposed to low doses of ozone at different concentrations and times. Bacterial inactivation (cultivability, membrane damage) was investigated using colony counts, resazurin as a metabolic indicator, and propidium iodide (PI). A fluorescent probe (H2DCFDA) was used for the ROS analyses;

Results: No reduction in the count colony was detected after O3 exposure compared to the control group. However, the cell viability of E. coli (30%), P. aeruginosa (25%), and A. baumannii (15%) was reduced considerably. The bacterial membrane of all strains was not affected by O3 but presented a significant increase of ROS in E. coli (90 ± 14%), P. aeruginosa (62.5 ± 19%), and A. baumanni (52.6 ± 5%);

Conclusion: Low doses of ozone were able to interfere in the cell viability of most strains studied, and although it does not cause damage to the bacterial membrane, increased levels of reactive ROS are responsible for causing a detrimental effect in the lipids, proteins, and DNA metabolism.

Denmark – Major outbreak of E. coli is probably due to spring onions in ready-to-eat cabbage salad

Posted on December 27, 2021 by | Leave a comment

SSI

The Statens Serum Institut (SSI) has seen an increase in the number of registered patients due to a special Escherichia coli (EIEC) in Denmark since 23 November 2021. The investigation shows that the source of infection is probably spring onions used in ready-to-eat cabbage salads, which are sold in three different retail chains.

Last edited December 27, 2021
Since mid-December, SSI, in collaboration with the Danish Veterinary and Food Administration, the DTU Food Institute and the clinical microbiological departments at the country’s hospitals, has been investigating the disease outbreak. From 23 November to 17 December 2021, 68 infections have been registered; 43 women and 25 men aged 1-91 years, and 20 people have been admitted to the hospital. The sick live throughout the country, except for the North Jutland region.

“This disease outbreak is unusual and extensive with 68 cases in three weeks. EIEC is a bacterium that usually affects travelers who have been to countries outside of Europe. When we saw a sudden increase in EIEC infection in Denmark, we were aware that there must be infection via a food ”
Epidemiologist Luise Müller from SSI

Ready-to-eat cabbage salad with spring onions

Interviews of patients have shown that several had eaten ready-made cabbage salads, and studies of purchasing data showed that the cabbage salads were purchased in the period from 15 to 30 November. Further investigation and tracing is still underway to uncover how the salads have been contaminated with the coli bacterium. For the time being, this indicates that the pollution has occurred at a subcontractor abroad.

The salads have been sold in i.a. REMA1000, COOP and Menu stores. They have a short shelf life of six days, and therefore there is no current risk with the cabbage salads that are on the shelves now.

Infects through food

EIEC is an intestinal bacterium that, like salmonella and campylobacter, typically spreads through food. Symptoms of an EIEC infection are acute stomach infection with diarrhea, general malaise, abdominal pain, possibly nausea, vomiting, and / or fever. The infection usually goes away on its own. Severe infections can manifest as dysentery (ie stool with blood, mucus and pus, fever and affected general condition).

What should you do if you have eaten that coleslaw?

If you have not had symptoms of an EIEC infection, or if you have had symptoms that have gone away on their own, do not do anything. In case of persistent symptoms or doubts, you can contact your own doctor.
