Global Health And Societal Impacts Of Schistosomiasis, William Ryan

Theses and Graduate Projects

Schistosomiasis, a parasitic infection, is classified as a Neglected Tropical Disease (NTD). While there are many NTDs that impact poor people across the world, schistosomiasis is one of the most prevalent. Currently 200 million people worldwide are infected with schistosomiasis and 800 million more are at risk for infection. Like other NTDs, this infection is preventable and treatable. Mass drug administration of the anti-parasitic drug praziquantel (the only drug available to treat schistosomiasis) is currently the main method of control. Although, China has recently demonstrated success by employing strategies that involve controlling the infection in the livestock population. Epidemiological surveys …

Increased Antibiotic Resistance Of Escherichia Coli In Nicaragua: Potential Causes And Future Implications, Ryan S. Paukert

Theses and Graduate Projects

Since 1987, no new structural class of antibiotic has been introduced into human medicine. Aside from the absence of a new structural class of antibiotics, there has been a startlingly low number of new antibiotics approved since 1987. With the lack of new antibiotics, finding current antibiotics that are effective is becoming an alarming challenge due to the worldwide emergence of antibiotic resistance. Antibiotic-resistant bacteria presents a major threat to public health because they reduce the effectiveness of antibiotic treatment leading to increased morbidity, mortality, and healthcare expenditure. Without treatment for common infections, like uropathogenic Escherichia coli (UPEC), resistant infections …
