The MAV_4644 dual-function channel protein with putative ADP-ribosyltransferase activity of Mycobacterium avium is required for virulence within host macrophages

Creator:: Lewis, Matthew S.
Abstract:: Mycobacterium avium subspecies hominissuis (MAH) is an opportunistic pathogen that is ubiquitous in the environment and often isolated from faucets and showerheads. MAH mostly infects humans with an underlying disease, such as chronic pulmonary disorder (COPD), cystic fibrosis (CF), or are immunocompromised, though infections in patients without concurrent disease are...

Recombinant vaccines against infectious hematopoietic necrosis virus : bacterial systems for vaccine production and delivery

Creator:: Simon, Benjamin E.
Abstract:: Several systems were examined for the production and delivery of recombinant vaccines for fish. C. crescentus was employed to produce a fragment of the IHNV glycoprotein. When administered by injection to 0.5 gram rainbow trout (Oncorhynchus mykiss), one of the fusion proteins (184 amino acids of the IHNV glycoprotein fused...

Molecular and cellular characterization of the intracellular phenotype of Mycobacterium avium

Creator:: Early, Julie V.
Abstract:: Mycobacterium avium cause disseminated disease in immunocompromised people such as AIDS patients. Subsequent to crossing the intestinal epithelium, M. avium thrive within vacuoles in macrophages. The bacteria exhibit a different, more invasive, phenotype after being in macrophages compared to M. avium from laboratory conditions. We hypothesized that this intracellular phenotype...

Investigation of unique marine environments for microbial natural products

Creator:: Thornburg, Christopher C.
Abstract:: Metagenomics has revealed that the marine microbial biosphere is immensely more diverse than originally considered, and is an almost untapped reservoir for the potential discovery of microbial natural products. Despite numerous advances in culturing, biosynthetic engineering and genomic-based screening efforts to uncover much of this diversity in relatively accessible environments,...

Clostridium perfringens spores : inactivation, germination, and formation

Creator:: Udompijitkul, Pathima
Abstract:: The enterotoxin-producing Clostridium perfringens type A isolates are responsible for the third most common foodborne illness in the United States and can also cause non-foodborne human gastrointestinal (GI) diseases such as antibiotic- associated and sporadic diarrheas. Three important factors contribute to the ability of C. perfringens to cause GI diseases,...

Characterization of germinant receptors in Clostridium perfringens non-food-borne isolates

Creator:: Banawas, Saeed S.
Abstract:: C. perfringens is a Gram-positive, spore-forming, anaerobic pathogenic bacterium capable of causing a wide variety of diseases in both humans and animals. However, the two most common illnesses in humans are C. perfringens type A food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) illnesses . These two major diseases are...

Inhibition of Clostridium perfringens spore growth by synergistic effects of different antimicrobials

Creator:: Alhabeeb, Rabiaa
Abstract:: Clostridium perfringens is a spore-forming anaerobic organism that is commonly present in fresh meat and poultry. The organism's spores can survive a range of food processing methods. C. perfringens type F isolates are the causative agents of C. perfringens type F food poisoning (FP) and non-food borne (NFB) human gastrointestinal...

The Inhibitory Activity of Essential Oil Constituents Against Clostridium perfringens Type A Isolates

Creator:: Alanazi, Saud
Abstract:: C. perfringens type A isolates are the causative agents of C. perfringens type A food poisoning (FP) and non-food-borne (NFB) human gastrointestinal diseases. In this study, we evaluated the antimicrobial effect of essential oil constituents (cinnamaldehyde, eugenol, allyl isothiocyanate (AITC), and carvacrol) against C. perfringens FP and NFB isolates grown...

Inactivation Strategy for Clostridium perfringens Spores Adhered onto Stainless Steel Surfaces

Creator:: Alzubeidi, Yasmeen S.
Abstract:: Clostridium perfringens is a spore-forming pathogenic bacterium that causes a variety of diseases in human and animals. C. perfringens type A isolates produce enterotoxin (CPE) causing food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) diseases including antibiotic-associated diarrhea and sporadic diarrhea. C. perfringens type A food poisoning currently ranks as...
