Campylobacter growth rates in four different matrices: broiler caecal material, live birds, Bolton broth, and brain heart infusion broth
No full textpeer-reviewedBackground
The objective of this study was to characterise Campylobacter growth in enrichment broths (Bolton broth, brain heart infusion broth), caecal material (in vitro), and in the naturally infected live broilers (in vivo) in terms of mean lag periods and generation times as well as maximum growth rates and population (cell concentration) achieved.
Methods
Bolton and brain heart infusion broths and recovered caecal material were inoculated with 10 poultry strains of Campylobacter (eight Campylobacter jejuni and two Campylobacter coli), incubated under microaerobic conditions, and Campylobacter concentrations determined periodically using the ISO 10272:2006 method. Caeca from 10 flocks, infected at first thinning, were used to characterise Campylobacter growth in the live birds. Mean generation times (G) (early lag to exponential phase) were calculated using the formula: G=t/3.3 logb/B. Mean lag times and µmax were calculated using the Micro Fit© Software (Version 1.0, Institute of Food Research). Statistical comparison was performed using GENSTAT ver. 14.1 (VSN International Ltd., Hemel, Hempstead, UK).
Results
The mean lag periods in Bolton broth, brain heart infusion broth, caecal material, and in the live bird were estimated to be 6.6, 6.7, 12.6, and 31.3 h, respectively. The corresponding mean generation times were 2.1, 2.2, 3.1, and 6.7 h, respectively; maximum growth rates were 0.7, 0.8, 0.4, and 2 generations h−1 and the maximum populations obtained in each matrix were 9.6, 9.9, 7.8, and 7.4 log10 CFU/g, respectively.
Conclusion
This study provides data on the growth of Campylobacter in a range of laboratory media, caecal contents, and in broilers which may be used to develop predictive models and/or inform science-based control strategies such as the maximum time between flock testing and slaughter, logistical slaughter, and single-stage depopulation of broiler units

Dentofacial parameters associated with the unilateral palatally impacted canine
No full textAims To investigate the relationship between unilateral PIC and specific dentofacial parameters. Materials and methods A sample of 216 subjects, with 108 subjects in the retrospective and prospective samples respectively. Dental parameters: The following dental parameters were assessed: Inter-canine and intermolar width; palatal depth and palatal area; anterior Bolton tooth-size discrepancy (TSD); maxillary arch shape and ratio and maxillary central and lateral incisor shape and ratio. Facial parameters: Three-dimensional (3D) images were taken for subjects in the prospective sample only, and were used to assess the following facial parameters: Face shape; face ratio and 3D distances and angles. Results Dental parameters: Inter-canine width was significantly smaller in the test group compared to the control group in the retrospective (p= 0.0002) and prospective (p= 0.0018) samples respectively. Anterior Bolton TSD was significantly higher in the prospective test group compared to controls (p= 0.0070). Arch ratio was significantly smaller in the test group than the control group for the retrospective sample (p= 0.0029), whereas no significant difference was recorded in the prospective sample (p= 0.1017). Arch shape distribution was significantly different in the retrospective sample (p= 0.009). Tooth shape distribution was significantly different for the maxillary right central incisor in the retrospective sample (p= 0.030). Tooth ratio showed no significant difference for both samples. Facial parameters: Basal width was significantly smaller in the test compared to the control group (p= 0.0001). No significant difference was found in all other 3D distances and angles measured. Conclusion Inter-canine width was significantly smaller in unilateral PIC subjects compared to controls. Anterior Bolton TSD was significantly higher in prospective unilateral PIC compared to controls. Maxillary arch ratio was significantly smaller in retrospective subjects. Square/tapered tooth shape was significantly more common in the retrospective group. Basal width was significantly smaller in subjects with unilateral PIC than controls
In the Company of Strangers
No full textRuby and Cat's friendship was forged on an English dockside sixty years ago when, as terrified children, they were shipped off to Australia. It was a friendship that was supposed to last a lifetime but when news of Cat's death reaches Ruby in London, it comes after years of estrangement. Declan too has drifted away from Cat but is forced back to her lavendar farm, Benson's Reach, by the terms of her will. He turns to his troubled friend Alice, who is desperate for a refuge. Can the magic of Benson's Reach triumph over the hurt of the past? Or is Cat's duty-laden legacy simply too much for Ruby and Declan to keep alive?" - Back cover

The microbiological safety and quality of foods processed by the "sous vide" system as a method of commercial catering
No full textEnd of Project ReportThe objective of this project was to improve the quality and safety of sous vide foods by investigating the responses of the food-poisoning microorganisms to the processing and storage conditions used in this technology. The major food poisoning bacteria of concern in sous vide foods are strains of Clostridium botulinum, Bacillus cereus, verotoxigenic Escherichia coli O157:H7 (VTEC), Salmonella spp., Listeria monocytogenes and Yersinia enterocolitica.Teagasc acknowledges with gratitude grant aid under the Food Sub-Programme of the Operational Programme for Industrial

Deliverable D-IA.2.2.OH-Harmony-Cap.3.1, Technical Report: Sampling and testing of Shiga toxin-producing Escherichia coli (STEC), Enterotoxigenic Escherichia coli (ETEC), Cryptosporidium and antimicrobial resistance (AMR) in Salmonella and Campylobacter spp. in the European Union
No full textThis is a public deliverable of One Health EJP Joint Research Project, Integrative Action-2.2, OH-HARMONY-CAP: One Health Harmonisation of Protocols for the Detection of Foodborne Pathogens and AMR Determinants. https://onehealthejp.eu/jip-oh-harmony-cap/.
This document, the first in a series of three reports, covers ‘sampling and testing’ procedures for Shiga toxin-producing Escherichia coli (STEC), Enterotoxigenic Escherichia coli (ETEC), Cryptosporidium spp. and antimicrobial resistance (AMR) in Salmonella spp. and Campylobacter spp. in the EU. Future reports will cover ‘characterisation’ and ‘data management and harmonised reporting’. The report is divided in sections covering each of the target microorganisms with subsections on current practices, best practices, detection methods and the latest sampling technological developments. The information provided on current practices is based on the responses to a questionnaire completed by European public health, veterinary and food testing institutions and National Reference Laboratories reached via the European Union Reference Laboratory (EURL), the European Food Safety Authority (EFSA) Zoonoses networks, European Centre for Disease Prevention and Control (ECDC) Food and Waterborne diseases network, among others. The other sections were prepared by experts in the respective areas, with reference to the peer reviewed and other relevant technical literature.Other contributors: Prof. Annemarie Kaesbohrer, Dr. Rosangela Tozzoli, Dr. Nadia Boisen, Dr. Flemming Scheutz, Dr. Hugo Guedes, Dr. Mónica Oleastro, Dr. Pikka Jokelainen, Dr. Karin Troell, Dr. Tryntsje Cuperus, Dr. Leonor Silveira, Dr. Miranda Kirchner, Catarina Flink, Dr. Gro Johannessen, Dr. Angela Pista, Dr. Angela van Hoeck, Dr. Robert Soderlund, Dr. C.
