Under normal conditions, fungi are ignored unless a disease/syndrome clinical signs are reported. The scientific communities are largely unaware of the roles fungi play in normal production parameters. Numerous preharvest interventions have demonstrated that beneficial bacteria can play a role in improving productions parameters; however, most researchers have ignored the impact that fungi may have on production. The goal of the present study was to record fungi recovered from commercial broiler and layer houses during production. Over 3,000 cecal samples were isolated using conventional culture methodology and over 890 samples were further characterized using an automated repetitive sequence-based PCR (rep-PCR) methodology. Eighty-eight different fungal and yeast species were identified, including Aspergillus spp., Penicillium spp., and Sporidiobolus spp, and 18 unknown genera were separated using rep-PCR. The results from the present study will provide a normal fungi background genera under commercial conditions and will be a stepping stone for investigating the impact of fungi on the gastrointestinal tract and on the health of poultry.
With one exception, which has been described as a suspended “kiva bell,” long stone rods have been interpreted throughout the archaeological literature of North America as whetstones or pestles. Two particularly long rods in a collection of prehistoric artifacts from New England raise questions as to the real use of some of these objects. The prevailing interpretations of the two artifacts may be incorrect, or at least incomplete, because the rods lack the kinds of wear that are found on most whetstones or pestles. They also have different acoustical properties from true pestles, which are usually shorter, and are identical in materials, acoustics, and form to probable prehistoric lithophones from the Old World, which can be played on the lap. The identification of the pair of rods as good candidates for being the first known cylindrical, two-toned prehistoric lithophones from New England introduces a new avenue for the study of fossil sounds and rituals in both the region and continent because it is likely that similar artifacts will be examined for characteristic wear, tested acoustically, and recognized as the objects of prestige and ceremony that they may have been in their role as un-suspended musical instruments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
