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...

Creator:: Cram, Erik D.
Abstract:: Chlamydia is a genus of obligate intracellular bacteria that undergo a unique, biphasic developmental cycle. The infectious and metabolically inert Elementary Bodies (EBs) begin the cycle of infection by attaching and invading a host cells. Once inside, the EBs differentiate into the metabolically active, dividing Reticulate Bodies (RBs) within their...

Creator:: Creason, Allison L.
Abstract:: Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

Creator:: Rose, Sasha J.
Abstract:: Respiratory infections caused by nontuberculous mycobacteria (NTM), especially Mycobacterium avium, can lead to progressive, recurrent disease that is refractory to therapy. Bacterial biofilms are intrinsically resistant to a variety of stressors and pressures, including host killing mechanisms and antibiotic therapy. Though it is becoming increasingly evident that NTM biofilms are...

Creator:: Alzhanov, Damir T.
Abstract:: The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...

Creator:: Chu, Hencelyn
Abstract:: Chlamydiae are obligate intracellular bacteria that infect a variety of eukaryotic hosts and affect normal host processes. Within host cells, their developmental cycle takes place inside non-acidified vacuoles termed inclusions. An inclusion membrane composed primarily of secreted chlamydial synthesized proteins called Incs encloses the inclusion. At this location, Incs have...

Creator:: Everman, Jamie L.
Abstract:: Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic inflammatory bowel disease that affects ruminant populations worldwide. The characteristic stages of the disease make diagnosis difficult, resulting in silent transmission among animals in a herd for years before proper detection of the infection. The extensive...

Creator:: Thomas, William J.
Abstract:: Symbioses between microbes and multicellular eukaryotes are found in all biomes, and encompass a spectrum of symbiotic lifestyles that includes parasitism and disease, commensalism, and mutually beneficial interdependent host-microbe relationships. Regardless of outcome, these symbiotic lifestyles are governed by a complex molecular "courtship" between microbe and potential host. This courtship...
