Evaluating protein-protein interactions of CpsA, a virulence factor in Group B Streptococcus
Streptococcus agalactiae, Group B Streptococcus (GBS), is an important human pathogen, causing life-threatening sepsis and meningitis in newborns. The virulence of GBS in part can be attributed to its ability to produce a polysaccharide capsule. CpsA has been recognized as an integral part of …

Assessment of Antimicrobial Resistance in Pathogens Responsible for Causing Bovine Mastitis in Kentucky
… of mastitis in Kentucky. Only one isolate of <em>Streptococcus agalactiae</em> was identified, indicating that this species is not prevalent in this state. <em>S. aureus</em> isolates were highly susceptible to all antibiotics used in the laboratory, with the only minor resistance seen in …

Analysis of the streptococcal cpsa protein in dna-binding and regulation of capsule and cell wall maintenance
<p>The systemic pathogens Streptococcus agalactiae (GBS) and Streptococcus pneumoniae remain a significant threat to human health worldwide. The ability of these organisms to cause systemic disease is compounded by the production of a polysaccharide capsule that provides immune evasion function. …

Comparison of Micrscan Identification and Susceptibility Testing Methods for Streptococcus Dysgalactiae to Conventional Biochemical Reactions and Kirby-Bauer Susceptibility Testing Methods
A total of 100 isolates of Streptococcus dysgalact iae from bovine mastitis infections was used to evaluate and compare the biochemical reactions of the gram positive Combo Type 6 panel on the MicroScan autoSCANR system to a conventional procedure for identification of streptococci. Of the 100 …

Molecular studies on streptococcal surface proteins
Streptococcus agalactiae and Streptococcus pyogenes are two related human pathogens causing different diseases. This thesis focuses on a number of surface proteins expressed by S. agalactiae and S. pyogenes and, more specifically, the molecular and biological characterization of these proteins. The …
