Characterization of the interaction between Mycobacterium avium subsp. paratuberculosis and bovine epithelial cells in culture and identification of invasion-associated genes by transposon mutagenesis

Creator:: Patel, Dilip
Abstract:: Mycobacterium avium subsp. paratuberculosis (MAP) is a cause of Johne's disease (JD) in cattle and other ruminants. MAP infection in the bovine host is not well characterized. It is assumed that crossing the bovine intestinal mucosa is important for MAP to establish infection. MAP's ability to infect bovine epithelial cells...

Immune response and protection against Streptococcus pyogenes after vaccination with Lactococcus lactis that expresses conserved region of M6 protein

Creator:: Mannam, Praveen
Abstract:: Most pathogens gain access to their host through mucosal surfaces. It is therefore desirable to develop mucosal vaccines that elicit an immune response to prevent this crucial first step in infection. Current mucosal vaccines are live attenuated strains of pathogens. More recent efforts have focused on the use of recombinant...

Bacillus subtilis endospore coat protein solubilization methods for studying effects of high pressure precessing

Creator:: Gandhi, Kalpesh K.
Abstract:: Spores of foodborne pathogens such as Clostridium botulinum, Clostridium perfringens and Bacillus cereus are widely distributed in nature. Presence of those spores in food products, particularly C. botulinum spores in vacuum packed, ready-to-eat low-acid products, is a great safety concern. The research here described is a first effort towards understanding...

Mechanisms for the interaction of environmental mycobacteria with host cells

Creator:: Harriff, Melanie J.
Abstract:: Environmental mycobacteria are important opportunistic pathogens for many hosts, including humans, cattle, and fish. Two well-studied species are Mycobacterium avium subsp. avium, a significant cause of disseminated bacterial disease in patients with AIDS, and Mycobacterium avium subsp. paratuberculosis, the cause of Johne’s disease in cattle. Many other species that are...

Detection and transmission of Mycobacterium marinum and Mycobacterium chelonae in zebrafish (Danio rerio)

Creator:: Peterson, Tracy Shawn
Abstract:: Mycobacteriosis is a common disease of laboratory zebrafish (Danio rerio). Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more wide spread and not associated with high mortality. Identification of mycobacterial infections to...

Pseudoloma neurophilia : progression of infection and transmission characteristics of a microsporidian parasite in a model vertebrate, Danio rerio

Creator:: Sanders, Justin L.
Abstract:: The microsporidian parasite, Pseudoloma neurophilia, is the most commonly diagnosed infectious disease in laboratory populations of the zebrafish, Danio rerio. Infections by P. neurophilia are generally subclinical, however, they can become acute either incidentally or due to experimental immune suppression. Non-protocol induced variation can confound results in laboratory experiments using...

Characterizing the Functional Properties of Otoferlin, Essential for Neurotransmission in Inner Hair Cells of the Cochlea

Creator:: Narayanappa, Murugesh
Abstract:: Hearing loss is one of the most common defect, affecting 360 million people worldwide due to several factors including congenital, present at or soon after birth or acquired with age. Congenital hearing loss affects 32 million children in the world. The economic impact of hearing loss is estimated to cost...

Pathways of infection of Phytophthora ramorum in rhododendron

Creator:: Lewis, Carrie D.
Abstract:: Phytophthora ramorum, a plant pathogen, is the cause of sudden oak death and ramorum blight and shoot die-back. It has a wide host range including many native forest species and common nursery plants. The lack of knowledge regarding infection biology of P. ramorum limits our understanding of its ecology and...

Ascospore viability and dispersal from pruned branches infected with Anisogramma anomala

Creator:: Heckert, Stephanie
Abstract:: Viability and dispersal of ascospores of Anisogramma anomala, the cause of eastern filbert blight (EFB) on European hazelnut, from diseased branches pruned from trees were measured. In each of two years, branches bearing stromata of A. anomala were cut in mid-December and compared to branches cut near budbreak in March,...

Characterization, epidemiology, and ecology of a virus associated with black raspberry decline

Creator:: Halgren, Anne B.
Abstract:: The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...
