Objective Measurement of 24-Hour Movement Behaviors in Preschool Children Using Wrist-Worn and Thigh-Worn Accelerometers.

In recent years, more attention has been paid towards the study of 24-h movement behaviors (including physical activity (PA), sedentary behavior (SB) and sleep) in preschoolers instead of studying these behaviors in isolation. This study aimed to evaluate the feasibility of using wrist- vs. thigh-worn accelerometers and to report accelerometer-derived metrics of 24-h movement behaviors in preschoolers.

Evaluation of a zinc chelate on clinical swine dysentery under field conditions.

Background: is the primary cause of swine dysentery, characterized by bloody to mucoid diarrhea due to mucohaemorhagic colitis in pigs and primarily affects pigs during the grow/finishing stage. Control and prevention of consists of administration of antimicrobial drugs, besides management and adapted feeding strategies. A worldwide re-emergence of the disease has recently been reported with an increasing number of isolates demonstrating decreased susceptibility to several crucially important antimicrobials in the control of swine dysentery.

Characterization of the Arcobacter contamination on Belgian pork carcasses and raw retail pork.

In the present study, the occurrence of Arcobacter was assessed at four sites on 169 porcine carcasses (foreleg, chest, pelvis and ham) at different stages of slaughter and 47 pork products at retail. Carcass swab samples were enriched in Arcobacter broth containing 5-fluorouracil, amphotericine B, cefoperazone, novobiocine and trimethoprim as selective supplement. After microaerobic incubation, arcobacters were isolated using Arcobacter selective agar plates, containing the selective supplement described above.

Prevalence, enumeration and strain variation of Arcobacter species in the faeces of healthy cattle in Belgium.

Arcobacter species were isolated from faeces of healthy cattle on three unrelated Belgian farms, using a quantitative isolation protocol. Isolates were identified by m-PCR and characterized by modified ERIC-PCR. The Arcobacter prevalence on the three farms ranged from 7.

Occurrence and strain diversity of Arcobacter species isolated from healthy Belgian pigs.

In this study, Arcobacter species were isolated from clinically healthy porkers and sows on four unrelated pig farms, using a quantitative isolation protocol. Isolates were identified by m-PCR, and fingerprints were distinguished by modified ERIC-PCR. The prevalence of Arcobacter in pigs ranged from 16 to 85%.

Isolation of Arcobacter species from animal feces.

A previously developed Arcobacter isolation protocol for poultry skin and meat was validated for the isolation of Arcobacter from feces of livestock animals. Good repeatability, in-lab reproducibility and sensitivity were achieved and the specificity was improved by additional incorporation of cycloheximide and increase of the novobiocin concentration in the selective supplement. The limit of detection of quantitative and qualitative analysis was 10(2) and 10(0) cfu g(-1) feces, respectively.
