The Relationship Between The Cervical Microbiome And Cervical Cancer Risk In Sub-Saharan Africa, Cameron Klein
The Relationship Between The Cervical Microbiome And Cervical Cancer Risk In Sub-Saharan Africa, Cameron Klein
School of Biological Sciences: Dissertations, Theses, and Student Research
Despite ongoing efforts, sub-Saharan Africa faces a higher cervical cancer burden than anywhere else in the world. Besides HPV infection, definitive factors of cervical cancer are still unclear. Dysbiosis of the cervicovaginal microbiota, particularly involving sexually transmitted infections, is associated with increased cervical cancer risk. Notably, HIV infection, which is prevalent in sub-Saharan Africa, greatly increases risk of cervicovaginal dysbiosis and cervical cancer. To better understand and address cervical cancer in sub-Saharan Africa, a better understanding of the regional cervicovaginal microbiome is required. In this study, I establish the relationship between cervical cancer, HPV, HIV, cervicovaginal infections, and the cervicovaginal …
Placental Hpv Infection In Hiv Positive And Hiv Negative Zambian Women, Chrispin Chisanga
Placental Hpv Infection In Hiv Positive And Hiv Negative Zambian Women, Chrispin Chisanga

Human papillomaviruses (HPVs) have been reported to infect epithelial trophoblastic cells of the placenta, induce cell death and even cause placental malfunction associated with spontaneous preterm delivery. To date, no study has been conducted to determine the role of HIV on HPV genotype distribution and pathogenesis in the placental compartment. This is despite the evidence that the human immunodeficiency virus (HIV) can decrease the cellular immune response and increase the incidence of malignant cancers in HPV patients. Therefore, in this study, we analyzed 200 genomic DNA (gDNA) samples extracted from paraffin embedded placental tissues of HIV positive and HIV negative …
Evolution Of Human Immunodeficiency Virus Type 1 Clade C Envelope V1-V5 Region During Disease Progression In Non-Human Primate Model, For Yue Tso
School of Biological Sciences: Dissertations, Theses, and Student Research
Human immunodeficiency virus type 1 (HIV-1) clade C strain is the fastest spreading HIV-1 strain globally, especially in Africa. It has been decades since the acquired immune deficiency syndrome (AIDS) pandemic first started. However, an effective anti-HIV-1 vaccine is not yet available, which is partly due to the highly variable nature of HIV-1 envelope gene and the absence of a suitable animal model. Strengthening of the understanding of envelope evolution during disease progression will contribute significantly towards future anti-HIV-1 treatment and preventions.
Non-human primates have been an essential animal model for many biomedical research areas. Using simian-human immunodeficiency virus (SHIV) …
