, commonly found in seafood products, is responsible for gastroenteritis resulting from the consumption of undercooked seafood. Hence, there is a need to characterize and quantify the risk involved from this pathogen. However, there has been no study reporting the quantification of hemolytic antimicrobial-resistant (AMR) in locally farmed shellfish in Singapore.

Article Synopsis
  • This study investigates the presence of haemolytic antimicrobial-resistant (AMR) pathogens in grey mullet fish, highlighting their occurrence in various stages of the food chain, including farm and retail environments.
  • The research found that haemolytic bacteria were detected in 60% of retail fish samples, with microbial loads varying between 1.9 to 4.1 Log CFU/g.
  • Risk assessments indicated that consumption of these fish could lead to an estimated 205 illness cases annually, emphasizing the importance of factors like fish handling and cooking in influencing food safety outcomes.

Enteritidis is a major foodborne pathogen worldwide. In this study, a total of 276 isolates, collected between 2016 and 2017 from human, food and farm/slaughterhouse samples, were studied to enhance the understanding of the epidemiology of human salmonellosis in Singapore. Results showed all 276 isolates belonged either to ST1925 (70.

The hypersensitive response (HR) is a form of programmed cell death of plant cells occurring in the local region surrounding pathogen infection site to prevent the spread of infection by pathogens. Bax, a mammalian pro-apoptotic member of Bcl-2 family, triggers HR-like cell death when expressed in plants. However, constitutive expression of the Bax gene negatively affects plant growth and development.

Antimicrobial resistance (AMR) in () poses a public health concern worldwide. Wild birds and rodents, due to their mobility, are potential vehicles for transmission of AMR bacteria to humans. Ninety-six wild birds' faecal samples and 135 rodents' droppings samples were collected and analysed in 2017.

Retrotransposons are mobile genetic elements capable of transposition via reverse transcription of RNA intermediates. Rice cultivar Nipponbare contains two nearly identical genomic copies of , an endogenous -like LTR retrotransposon, on chromosomes 7 ( ) and 10 ( ), respectively. Previous studies demonstrated that only is active in transposition during tissue culture.
