Tetracycline (Tet)-resistant strains of Chlamydia suis were isolated from swine
farms in the Midwest. The isolation of the resistant strains was significant
because Tet is an antibiotic used to treat infections by veterinarians and
doctors. One of the tetracycline (Tet)-resistant strains, R19, was able to
survive in Tet up to...
The Chlamydiaceae are a family of obligate intracellular bacteria with a unique biphasic developmental cycle. The replicating, metabolically active, intracellular phase bacteria (RBs) grow within a cellular vacuole know as the inclusion. Since the proteins the Chlamydiaceae secrete into this membrane are the means of host/parasite interaction, they have long...
As part of a participatory research project, where farmers and Oregon State University researchers collaborated, aspects of potato (Solanum tuberosum L.) growing systems were studied. It was determined through conversations with the farmers that quantification of certain growth parameters of potato was lacking, including dry matter accumulation, crop nitrogen (N)...
Streptococcus gordonii is a bacterial species that naturally colonizes the oral cavity of most healthy humans. It resides in the mouth as an adherent to dental surfaces and, with few exceptions, does not cause disease in individuals it inhabits. It possesses qualities that encourage its use as a vector to...

A need exists to develop a non-destructive testing technique that can identify
the formation and propagation of diagonal tension cracks in conventionally
steel reinforced concrete deck girder (RCDG) highway bridges in the State of
Oregon. Such a technique could be included into a structural health
monitoring (SHM) system installed on...

Umatilla is the progeny of a cross between Butte and A77268-4. This Oregon selection was evaluated as AO82611-7 in numerous Oregon and western regional trials. The long, medium russetted tubers of Umatilla are well suited for processing, but lack the attractiveness to compete in the fresh market arena.
Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...
