Oxydifficidin-Producing Bacillus Presents Novel Antimicrobial Activity Against Neisseria Gonorrhoeae Involving The Deda Protein, Jingbo Kan
Dissertations, Theses, and Capstone Projects
Bacterial human pathogens cause severe infectious diseases which are the second most common cause of death next to cancer and cardiovascular diseases in the world, especially in developing countries. Gonorrhea particularly, is the second most common sexually transmitted infection (STI) which is caused by the microorganism Neisseria gonorrhoeae (GC). Centers for Disease Control and Prevention (CDC) estimates that more than 1.6 million new gonorrhea cases emerged in USA in 2018 (“Detailed STD Facts - Gonorrhea” n.d.). Also, the WHO (World Health Organization) shows that gonorrhea is the most antibiotic resistant STI (“PAHO/WHO | Gonorrhea” n.d.), highlighting the shortage of efficient …
The Role Of The Msaabcr Operon In Cell Wall Integrity And Programmed Cell Death During Biofilm Development, Bibek G C
Dissertations
Staphylococcus aureus is an important human pathogen in both community and health care settings. Biggest challenges with S. aureus as a pathogen is its ability to acquire antibiotic resistance and produce robust biofilms. In this work, we investigated the nature of the cell wall defect in the msaABCR operon mutant in the Mu50 (VISA) and USA300 LAC methicillin-resistant Staphylococcus aureus (MRSA) strains. Results showed that msaABCR-mutant cells had decreased cell wall thickness and cell wall crosslinking in both strains. These defects are most likely due to increased murein hydrolase activity and/or nonspecific processing of murein hydrolases mediated by increased …
Pathogenicity Of Staphylococcus Agnetis Associated With Lame Broilers With Osteomyelitis, Sura Faris Salih Zaki
Pathogenicity Of Staphylococcus Agnetis Associated With Lame Broilers With Osteomyelitis, Sura Faris Salih Zaki
Graduate Theses and Dissertations
We developed High Resolution Melt Analysis (HERMA) as a rapid and reliable molecular diagnostic assay for the detection and identification of the main bacterial species recovered from the blood and lesions of bacterial chondronecrosis with osteomyelitis (BCO) from the lame broilers at the University of Arkansas poultry research farm. Also, the present study confirms that raising young birds on suspended wire flooring has been proved to successfully induce lameness attributable to BCO with birds being more susceptible to bacteraemia than those that were raised on litter flooring. The newly described pathogen, Staphylococcus agnetis, has been reported to be overrepresented in …
