Antimicrobial Activity of Green Synthesized Silver Nanoparticles Against Selected Gram-negative Foodborne Pathogens.

Silver nanoparticles (AgNPs) used in this study were synthesized using pu-erh tea leaves extract with particle size of 4.06 nm. The antibacterial activity of green synthesized AgNPs against a diverse range of Gram-negative foodborne pathogens was determined using disk diffusion method, resazurin microtitre-plate assay (minimum inhibitory concentration, MIC), and minimum bactericidal concentration test (MBC).

Prevalence, Virulence Genes and Antimicrobial Resistance Profiles of Serovars from Retail Beef in Selangor, Malaysia.

The aim of the present study was to investigate the prevalence of spp., Enteritidis and Typhimurium in retail beef from different retail markets of Selangor area, as well as, to assess their pathogenic potential and antimicrobial resistance. A total of 240 retail beef meat samples (chuck = 60; rib = 60; round = 60; sirloin = 60) were randomly collected.

Prevalence and Antimicrobial Susceptibility of Isolated from Short Mackerels () in Malaysia.

Numerous prevalence studies and outbreaks of infection have been extensively reported in shellfish and crustaceans. Information on the quantitative detection of in finfish species is limited. In this study, short mackerels () obtained from different retail marketplaces were monitored with the presence of total and pathogenic strains of .

Prevalence and quantification of Listeria monocytogenes in beef offal at retail level in Selangor, Malaysia.

A total of 63 beef offal samples (beef liver = 16; beef lung = 14; beef intestine = 9; beef tripe = 15; beef spleen = 9) from three wet markets (A, B, and C) in Selangor, Malaysia were examined for the prevalence and microbial load of Listeria monocytogenes. A combination of the most probable number and polymerase chain reaction (MPN-PCR) method was employed in this study. It was found that L.
