Identifying Potential Antibiotic Uptake Mechanisms Of Streptococcus Pneumoniae, Yuri Laguna Terai
Identifying Potential Antibiotic Uptake Mechanisms Of Streptococcus Pneumoniae, Yuri Laguna Terai
Theses and Dissertations
Streptococcus pneumoniae (pneumococcus) is a commensal gram-positive colonizer of the human nasopharynx capable of causing diseases including otitis media, pneumonia, bacteremia, and meningitis. Although it is often a harmless colonizer, there is a high rate of mortality and morbidity among the immunocompromised, elderly, and young children. While these infections can often be treated with antibiotics, resistance to numerous antibiotics is increasing. Antibiotic resistance is a well-studied dilemma; however, little information is known of how bacteria take up certain antibiotics. Because most antibiotics cannot diffuse freely across the bacterial cell wall, we hypothesize that metabolite transport proteins participate in the uptake …

Evaluating Simulated Tarnished Plant Bug Damage During Late Bloom On Cotton Yield, Seth Thomas Permenter
Theses and Dissertations
The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is an important economic pest of cotton, Gossypium hirsutum (L.), in the Midsouth region of the United States. Continuous season long infestations may result in four or more insecticide applications per growing season. However, late season applications may only be preventing minor losses when compared to overall yield. Results from this study suggest an opportunity to increase thresholds and potentially eliminate one to two insecticide applications in late bloom. Results from this experiment show no significant differences in yield when all square removal levels were simulated in the fourth and fifth …
