Detection and characterisation of Salmonella enterica serovar Hvittingfoss in Bar-tailed Godwits (Limosa lapponica) from Roebuck Bay, north-western Australia.

Detection and characterisation of Salmonella enterica serovar Hvittingfoss in Bar-tailed Godwits (Limosa lapponica) from Roebuck Bay, north-western Australia. Appl Environ Microbiol. 2020 Jul 31;: Authors: Smith HG, Bean DC, Hawkey J, Clarke RH, Loyn R, Larkins JA, Hassell C, Valcanis M, Pitchers W, Greenhill AR Abstract Salmonella enterica serovar Hvittingfoss is an important foodborne serotype of Salmonella, being detected in many countries where surveillance is conducted. Outbreaks can occur, including a recent multi-state foodborne outbreak in Australia. S Hvittingfoss can be found in animal populations, though a definitive animal host has not been established. Six species of birds were sampled at Roebuck Bay, a designated Ramsar site in north-western Australia, resulting in 326 cloacal swabs for bacterial culture. A single flock of 63 Bar-tailed Godwit (Limosa lapponica menzbieri) caught at Wader Spit, Roebuck Bay in 2018, resulted in 17 (27%) culture-positive for Salmonella spp. All other birds were negative for Salmonella. The isolates were identified as Salmonella enterica serovar Hvittingfoss. Phylogenetic analysis revealed a close relationship between isolates collected from godwits and the S. Hvittingfoss responsible for a 2016 multi-state foodborne outbreak originating from tainted cantaloupes (rock melons) in Australia. While it is not possible to determine how this strain of S. Hvittingfoss was introduced into the Bar-tailed Godwits, these ...

Abstract Background: The 21st century has seen a wide range of diseases resulting from zoonotic infections, of which bacterial infections have led to outbreaks of food-borne diseases. Aim: The study looks at bacterial pathogen carriage by farm rats and their antimicrobial susceptibility, with the view of providing insights for antimicrobial surveillance. Method: Farm rats of Rattus rattus species where randomly collected alive from farms in Al-Ahsa using food baits. They were anaesthetize with urethane within 4 h of collection and were unconscious for the collection of samples. Basic bacteriologic...

(BfR Federal Institute for Risk Assessment) To make food even safer for humans, experts from scientific institutions, food regulatory authorities and the business community will discuss current developments and strategies at the 'Zoonoses and Food Safety' Symposium at the German Federal Institute for Risk Assessment (BfR) on 4 and 5 November 2019, in Berlin-Marienfelde. Because some micro-organisms in food can cause health problems. Campylobacter in raw milk, salmonella in eggs or listeria in ready-to-eat foods often lead to outbreaks affecting numerous patients.

In conclusion, the results improve our understanding on the characteristics of lncRNAs and mRNAs on regulating host immune response against C. perfringens type C infection, which will provide a reference for future research into exploring C. perfringens-related diseases in human. Introduction Clostridium perfringens (C. perfringens) is a Gram-positive anaerobic rod and ranks as the second most common bacteria that causes fulminant, fatal infectious and immune diseases (Scharff, 2012; Grass et al., 2013). These diseases are characterized by fever, pain, gas production, local edema, and severe tissue destruction, the...

Conclusion Starter cultures are an important tool that contributes to ensure the safety of fermented meat products. Indeed, the microorganisms that constitute starter cultures may inhibit or reduce the growth of spoilage and/or pathogenic populations through mechanisms, such as production of certain metabolites or competitive exclusion. Thus, the use of starter cultures may reduce the need for chemical additives, such as nitrites and nitrates. Furthermore, the lower residual levels of nitrates and nitrites detected in fermented meat products inoculated with starter cultures are due to the ability of starters to metabolize...

This study provides new insight into the characterization of foodborne C. perfringens and highlights the potential of WGS for the investigation of FBOs. Introduction Clostridium perfringens is a Gram-positive, spore-forming, anaerobic, rod-shaped bacterium, known as an important causative agent of foodborne and non-foodborne gastroenteritis (Grass et al., 2013). The ability of this bacterium to form resistant spores contributes to its survival in many environmental niches, including soil, sewage, foods, and the intestinal microbiota of humans and animals (Xiao, 2014; Li et al., 2016). C. perfringens can cause necro...

In this study, a “species” is defined as a unique AMR profile, including the profile corresponding to susceptibility to all tested antimicrobials. The AMR profile (or antibiogram) of an isolate is the combination of AMR phenotype (susceptible or non-susceptible) to each drug tested. SR reflects the richness of AMR profiles without weighting of abundance. SE and SD are measures in which both SR and relative abundance are taken into account. The BP diversity index is related to the proportion of isolates with the most common AMR profile. Changes in antimicrobial testing protocol could impact upon results, partic...

In conclusion, association rule mining is an effective tool for identifying patterns of multidrug resistance within antimicrobial susceptibility testing data and evaluating the statistical and biological significance of the patterns. Rule quality measures used to sort and differentiate rules should be tested using resampling procedures to minimize the false discovery rate. Rule mining identified consistent multidrug resistance patterns involving beta-lactams, sulfisoxazole, tetracycline, gentamicin, and streptomycin in E. coli isolated from chicken carcasses and meat between 2004 and 2012. The generally low rule overlap su...

Abstract Zoonoses such as Brucella, Mycobacterium bovis, Campylobacter, Salmonella, Escherichia coli, Listeria, etc. are spread by ingestion of contaminated unpasteurised milk products (from infected cattle) and result in infectious outbreaks, hospitalisations and mortality. In Southeast Asian countries, raw goat's milk is sometimes used for dengue infection-associated thrombocytopenia; however, evidence to support this sociocultural practice is lacking. A peak incidence of brucellosis cases may occur after a dengue season in communities where this practice is prevalent. PMID: 30895885 [PubMed - as supplied by publisher]

In conclusion, this outbreak investigation highlighted the importance of close collaboration between regional Public Health Services, the NVWA, the RIVM and diagnostic laboratories. Through a combined microbiological, epidemiological and source tracing approach, raw and undercooked beef products could be identified as the source of the S. Typhimurium outbreak. This outbreak yet again emphasizes the importance of awareness among consumers of the risk of infection when consuming or handling raw meat products. To increase transparency for consumers, we recommend adding warning labels to risk food products. Competing Intere...
