Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii which is endemic in cattle, sheep and goats in much of the world, including the United Kingdom (UK). There is some epidemiological evidence that a small proportion of cases in the developed world may arise from consumption of unpasteurised milk with less evidence for milk products such as cheese. Long maturation at low pH may give some inactivation in hard cheese and viable C.

Fusarium armeniacum has been found as a saprophyte on natural grasses devoted to cattle feed in Argentina. This species has been reported as highly toxigenic due to the production of trichothecenes type A, but the information available about its toxigenic profile is incomplete. Thus, the aim of the present study was to determine the toxigenic ability of 50 F. armeniacum isolates recovered from natural grasses using a multitoxin method based on LC-MS/MS.

Aflatoxins are a class of mycotoxins that impair poultry health and performance. Some clays have the ability to adsorb aflatoxins. In our study, mineralogical composition of the tested clays was confirmed by powder X-ray diffraction and simultaneous thermal analysis and their properties like pH, electrical conductivity, exchangeable cations, cation exchange capacity and clay content were determined.

The aim of present study was to reveal the toxicokinetic properties and absolute oral bioavailability of deoxynivalenol (DON) in turkey poults. Six turkey poults were administered this Fusarium mycotoxin per os and intravenously in a two-way cross-over design. Based on non-compartmental analysis, DON was absorbed rapidly (Tmax= 0.57 h) but incomplete, as the oral bioavailability was only 20.9%.

Direct analysis in real time (DART) ionisation coupled to mass spectrometry (MS) was used for the rapid quantitative analysis of T-2 toxin (T-2) and the related HT-2 toxin (HT-2), extracted from maize. Sample preparation procedures and instrument parameters were optimised to obtain sensitive and accurate determination of the toxins. The lowest calibration levels were 50 μg/kg for T-2 and 300 μg/kg for HT-2.

Neha Rajpara, Braj Mohan Ram Narayan Singh Kutar, Ritam Sinha, Dhrubajyoti Nag, Hemanta Koley, Thandavarayan Ramamurthy and Ashima Kushwaha Bhardwaj The isolates of Vibrio cholerae and Providencia vermicola obtained from a diarrheal patient were investigated for genetic elements governing their drug resistance phenotypes. Out of 14 antibiotics tested, V. cholerae Vc IDH02365 isolate showed resistance to nine antibiotics, while P.

Quorum sensing (QS) is a process of cell-to-cell communication that enables bacteria to transition between individual and collective lifestyles. QS controls virulence and biofilm formation in Vibrio cholerae, the causative agent of cholera disease. Differential RNA sequencing (RNA-seq) of wild-type V. cholerae and a locked low-cell-density QS-mutant strain identified 7,240...

Giardia intestinalis is a pathogen associated with foodborne outbreaks and Escherichia coli is commonly used as a marker of faecal contamination. Implementation of routine identification methods of G. intestinalis is difficult for the analysis of vegetables and the microbiological detection of E. coli requires several days. This study proposes a PCR-based assay for the detection of E. coli and G. intestinalis cysts using crude DNA isolated from artificially-contaminated lettuce. The G.

Five enterococcal strains (Enterococcus faecalis LS15, PF03, BF10 and SL13 and Enterococcus faecium MM08) were isolated and identified from 130 probiotic products marketed in China. The determined biological characteristics were acid tolerance, bile tolerance, pepsin tolerance, trypsin tolerance, organic acid production and antimicrobial activity. Safety examination of potential virulence factors and antibiotic resistance were also performed.

Loop-mediated isothermal amplification (LAMP) based on lmo0460 sequence in genome of Listeria monocytogenes (L. monocytogenes) was designed for detection of L. monocytogenes, which is an important foodborne kind of pathogenic bacteria causing human and animal disease. The primers set for lmo0460 sequence encoding membrane-associated lipoprotein consist of four specific primers targeting six regions on specific fragment.

The aim of this study is to investigate the antibacterial characteristics and mechanisms of nutmeg oil. In this paper, 54 chemical compositions of nutmeg oil were analyzed by gas chromatography–mass spectrometry (GC–MS). The major volatile components of nutmeg oil were sabinene (39.12%) and alpha-pinene (11.96%).
