Pristionchus entomophagus is a necromenic nematode commonly associated with dung beetles (Geotrupes spp.) in Europe. Recently, it has been found in Maine emerging from cadavers of M. rubra, an ant native to Europe that is currently established and pestiferous in Maine (Groden and Stack 2011). Laboratory assays inoculating M. rubra with these nematodes caused significant mortality. This study aimed to characterize the bacterial associates of P. entomophagus in order to further understand its pathogenic relationship with M. rubra. Bacterial samples were collected from the cuticle and gut of the nematodes, and the hemolymph of infected hosts. Single spore isolates were …
A Multidisciplinary Approach To Food Safety Evaluation: Hummus Spoilage And Microbial Analysis Of Kitchen Surfaces In Residential Child Care Institutions (Rcci) In Massachusetts, U.S.A., Elsina E. Hagan
Masters Theses 1911 - February 2014
Food borne illnesses continues to be a public health challenge in the United States (U.S.); an estimated 9.4 million incident cases occurred in 2011. In view of this challenge we conducted two food safety studies; 1) related to product formulation (hummus spoilage challenge study) and 2) evaluating the microbial safety of domestic kitchen surfaces in Residential Child Care Institutions (RCCI pilot study).
Hummus is of Mediterranean origin but is currently eaten globally. This challenge study evaluates a variety of industrial hummus formulations (four in total, differing in pH and/or addition of a preservative (natamycin). Two batches were setup: batch 1; …
