AIMS To characterise the occurrence of Cronobacter in milk powder factories. METHODS AND RESULTS Cronobacter was isolated from 32% of 298 environmental samples from five factories. More isolations occurred in nonprocessing (49%) than processing areas (29%), although the greatest occurrence was in a single milk powder area during shutdown maintenance (81%)(More)
BACKGROUND Because adenosine has been alleged to produce both anesthetic and analgesic sparing effects, a randomized, double-blinded study was designed to compare the perioperative effects of adenosine and remifentanil when administered as intravenous adjuvants during general anesthesia for major gynecologic procedures. METHODS Thirty-two women were(More)
OBJECTIVES The main objective of this study was to determine the impact of transport and lairage on the isolation rate and the number of Escherichia coli O157 on cattle. MATERIALS Ninety animals, divided into three groups (A, B, and C) of 30 animals each, were used in this study. Individual animals were tagged, and samples were collected from the hides(More)
BACKGROUND Opioid-related side effects associated with intravenous patient-controlled analgesia can be reduced by a low-dose naloxone infusion. The influence of nalmefene, a pure opioid antagonist with a longer duration of action, on opioid-related side effects has not been evaluated. This study was designed to determine the dose-response relation for(More)
A survey was conducted to determine the relative prevalence of Salmonella serovars on whole chicken carcasses before and after processing in 3 Australian poultry abattoirs. Ninety and 180 whole chicken carcasses were tested for Salmonella serovars before and after processing, respectively. Each carcass was subjected to a buffered peptone water rinse(More)
The ability of Campylobacter jejuni strains to attach to stainless steel as they became nonculturable during storage in distilled water at 4 degrees C for 30 days was investigated. From an initial count of approximately 7 log colony-forming units/mL all strains completely lost culturability by day 20, but the numbers of cells attaching to stainless steel(More)
UNLABELLED Corticosteroids can decrease pain and postoperative nausea and vomiting after ambulatory surgery. Therefore, we designed a study to evaluate if the routine use of dexamethasone would facilitate the early recovery process after anorectal surgery. A secondary aim of the study was to determine if dexamethasone would increase the incidence of(More)
AIM To determine if Campylobacter jejuni grown at 37 and 42 degrees C have different abilities to survive on beef and chicken, and in water. METHODS AND RESULTS Beef, chicken and water were separately inoculated with four Camp. jejuni (two poultry and two beef) strains grown at 37 or 42 degrees C. The matrices were stored at approximately 4 degrees C and(More)
Slices of cooked meats were inoculated with Listeria monocytogenes strain Murray B, vacuum-packed and stored at either 0 or 5 degrees C. Decreases in pH (6.9-5.9) and aw (0.993-0.960; adjusted with sodium chloride) of the cooked meats increased the lag time and reduced the growth rate at 5 degrees C. The type of meat (beef, pork, chicken or turkey) had no(More)
