For cooked, ready-to-eat products: • If at any time the product is held at internal temperatures above 80°F (26.7°C), exposure time (i.e., time at internal temperatures above 50°F (10°C) but
The antibacterial activity of garlic paste and FGE against commensal and pathogen enteric bacteria such as Escherichia coli, E. coli O157:H7, Salmonella species, Shigella species, Vibrio species, Campylobacter species, Listeria monocytogenes, Enterobacter, and Enterococcus species, Lactobacillus acidophilus, Staphylococcus aureus, Streptococcus
Numerous Lactobacillus strains have been shown to be active against the main pathogens responsible for bacterial infections of the vaginal and urinary tract [].In order to obtain further information about the mechanisms by which Lactobacillus spp. can counteract the growth of bacterial vaginal pathogens, the antimicrobial effect of two Lactobacillus strains (Lactobacillus rhamnosus SD5675 and
Clinical bovine mastitis caused by Escherichia coli (E. coli) leads to endotoxin shock and death in extreme cases (3, 4). Although many countries have improved farm management practices and reduced the incidence, mastitis caused by E. coli has proven difficult to solve ( 5 ).
E. coli was screened for Shiga toxins (Stx 1 and Stx 2) and Intimin (eae) virulence genes as well as antibiotic resistance. The spot-on-the-lawn method was used to evaluate antimicrobial activity. Eighteen isolates were acid stable and are identified as E. coli, Shigella, and Lysinibacillus. The Stx 2 gene and antibiotic resistance were
1. Introduction. Microbial pathogens in food may cause spoilage and contribute to foodborne disease incidence, and the emergence of multidrug resistant and disinfectant resistant bacteria—such as Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), and Pseudomonas aeruginosa (P. aeruginosa)—has increased rapidly, causing the increase of morbidity and mortality [].
Bottom line. Bacteria begin to die at 149°F (65°C), but boiling water for one minute is still a good precaution. The optimal temperature to kill bacteria in food depends on the food type
This work evaluated the ability of two probiotic strains, Lactobacillus plantarum and Lactobacillus rhamnosus, in displacing pre-formed biofilms of Escherichia coli and Staphylococcus aureus from medical-grade silicone. Single-species biofilms of 24 h were placed in contact with each probiotic suspension for 6 h and 24 h, and the reductions in
A wide range of antibacterial activity was demonstrated by eugenol against the test pathogens with MIC ranging from 0.0312 to 8 μg/mL. The corresponding MBC of the compound was 2-4 fold higher. Time kill curve revealed eugenol to effectively reduce E. coli to undetectable levels within 4 h.
