The acquisition and internalization of Salmonella by the lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
In poultry broiler production facilities, it is important to understand the sources and contribution of reservoir populations of pathogens. The lesser mealworm beetle, Alphitobius diaperinus (Panzer), is a common pest in poultry litter that is reported to carry pathogens affecting both human and animal health. This study investigates whether the carriage of a bacterial pathogen occurs by the ha...
متن کاملEvaluation of Salmonella movement through the gut of the lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
AIMS The lesser mealworm, Alphitobius diaperinus is an important poultry pest prevalent during production that is capable of vectoring pathogens. This study was undertaken to determine the gut transit time of Salmonella for biosecurity risk analysis of pathogen dispersal into the environment. METHODS Adult and larval A. diaperinus were exposed to two concentrations of a fluorescently labeled ...
متن کاملConjugative transfer of plasmid-located antibiotic resistance genes within the gastrointestinal tract of lesser mealworm larvae, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
The frequency of conjugative transfer of antimicrobial resistance plasmids between bacteria within the gastrointestinal tract of lesser mealworm larvae, a prevalent pest in poultry production facilities, was determined. Lesser mealworm larvae were exposed to a negative bacterial control, a donor Salmonella enterica serotype Newport strain, a recipient Escherichia coli, or both donor and recipie...
متن کاملTransient gut retention and persistence of Salmonella through metamorphosis in the lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
AIMS This study was undertaken to determine the retention of Salmonella through Alphitobius diaperinus metamorphosis and its contribution, through defecation, to external contamination. METHODS AND RESULTS Insects were exposed to a tagged Salmonella enterica and evaluated for external elimination. (i) Each day for 3 weeks, a filter collected frass from a restrained insect for analysis. (ii) E...
متن کاملCharacterization of the larval stages of Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae) using head capsule width.
The mean width (n = 5) of the cephalic capsule instar of Alphitobius diaperinus was determined. The larvae were reared at 27 degrees C (+/- 0.1 degrees C). The result showed that A. diaperinus has eight larval instars. The head capsule of the 1st instar larvae measured x = 0.228 (SD = 0.0192) and the last instar larval measured x = 1.339 (SD = 0.0436). The developmental rate, determined by Dyar...
