The Evolution And Effectiveness Of Sterile Insect Technique For Vector Control: A Historical And Modern Analysis, Katerina Karaiskos

Public Health Theses

Sterile Insect Technique (SIT) has emerged as an important tool in the control of vector-borne diseases, providing an alternative to traditional chemical insecticides. Initially based on the irradiation of insects to induce sterility, SIT has proven effective in eradication campaigns, including the cases of the screwworm and tsetse fly. SIT’s primary strengths lie in its species specificity, environmental safety, and the avoidance of pesticide resistance. However, “classic” irradiating SIT is limited by high operational costs, reduced mating competitiveness of sterilized males, and difficulties in addressing high-density vector populations. Recent advancements in genetic-based SIT methods, such as the Release of Insects …

Assessing The Cross-Species Vaccine Potential Of Pfripr Using Transgenic Chimeric Plasmodium Knowlesi Models, Peiqi Li

Public Health Theses

Malaria remains a major global health burden, with an estimated 263 million cases and597,000 deaths reported in 83 countries in 2023 (1). While P. falciparum is responsible for the most severe cases, non-falciparum species such as P. vivax, P. ovale curtisi, P. ovale wallikeri, P. malariae, and P. knowlesi also pose significant public health risks, particularly in co-endemic regions. Current malaria vaccine efforts mainly focus on P. falciparum which is reasonable because over 90% of the global malaria-related morbidity and mortality are caused by P. falciparum (2). However, laying emphasis on targeting P. falciparum leaves a critical gap in cross- …
