E. Coli outbreak sickens nearly 100 in five states, and nobody knows where it’s coming from

One food-borne illness expert said it's "perplexing" the CDC has yet to pinpoint the source to a specific food item, grocery store or restaurant chain.

ConclusionThe probability of virus detection is independent of the time between notification of the outbreak or symptom onset and sample collection. Our results suggest possible defects in cleaning protocols and disinfection in closed and semi-closed settings.

This study aimed to evaluate: (i) the effectiveness of plasma activated water (PAW) on the germination capacity of mung bean seeds and (ii) the antimicrobial capacity of PAW. A specially designed set-up composed of two electrochemical cell was used to produce two different types of PAW, by surface plasma discharge ignited from copper cathode and copper anode, respectively. The germination capacity of mung bean seeds was assessed over 96 h incubation in the dark at 25 °C. The antimicrobial capacity of PAW was assessed against 6 h exposure to Escherichia coli NCTC 12900. The anodic PAW (rich in NO3−) indicate...

This study examines the concentrations of aerobic bacteria and E. coli in ward environments and the airborne transmission of bacterial drug resistance. The results show that the three wards examined have an average aerobic bacterial concentration of 132 CFU∙m-3 and an average inhalable aerobic bacterial concentration of 73 CFU∙m-3, with no significant difference (P > 0.05) among the three wards. All isolated E. coli showed multi-drug resistance to not only third-generation cephalosporin antibiotics, but also quinolones, aminoglycosides, and sulfonamides. Furthermore, 51 airborne E. coli strains i...

AbstractGiardia is a zoonotic gastrointestinal parasite responsible for a substantial global public health burden, and quantitative microbial risk assessment (QMRA) is often used to forecast and manage this burden. QMRA requires dose –response models to extrapolate available dose–response data, but the existing model forGiardia ignores valuable dose –response information, particularly data from several well‐documented waterborne outbreaks of giardiasis. The current study updatesGiardia dose –response modeling by synthesizing all available data from outbreaks and experimental studies using a Bayesi...

This study was conducted to evaluate immunostimulation by Escherichia coli HSP70 (DnaK) in axenic European sea bass larvae in order to protect the larvae against vibriosis. DnaK stimulates the immune response in crustaceans and juvenile fish against bacterial infections. The use of axenic fish larvae allows to study immunostimulation in the absence of an interfering microbial community. At 7 days post-hatching, larvae received a single dose of alginate encapsulated recombinant DnaK. Two non-treated control groups in which animals either received empty alginate microparticles (C1) or no alginante microparticles (C2 and C3) ...

l M Abstract Salmonella enterica is a foodborne pathogen often leading to gastroenteritis and is commonly acquired by consumption of contaminated food of animal origin. However, frequency of outbreaks linked to the consumption of fresh or minimally processed food of non-animal origin is increasing. New infection routes of S. enterica by vegetables, fruits, nuts and herbs have to be considered. This leads to special interest in S. enterica interactions with leafy products, e.g. salads, that are mainly consumed in minimally processed form. The attachment of S. enterica to salad is a crucial step in contamination, bu...

Cryptosporidium and Giardia are ubiquitous protozoan parasites that infect a broad range of vertebrate hosts, including domestic and wild animals as well as humans. Both parasites are of medical and veterinary importance. Infections with Cryptosporidium and Giardia in ruminants are associated with diarrhea outbreaks, mainly in young animals. Ruminants are potential sources of infection for humans because some species of Cryptosporidium and assemblages of Giardia duodenalis have been isolated from both ruminants and humans. Knowledge of these parasites has greatly expanded in the last 2 decades from simple microscopic obser...

(Flinders University) Salmonella is a key cause of foodborne gastroenteritis around the world, with most outbreaks linked to eggs, poultry meat, pork, beef, dairy, nuts and fresh produce. Now Flinders University researchers have found a simple solution for preventing salmonellosis affecting eggs through surface contamination, giving crucial help for food services industries.
