Evaluation Of Ocelot And Bobcat General And Reproductive Health In South Texas And Assessment Of Assisted Reproductive Techniques For Wild Felid Conservation, Ashley Reeves Dec 2022

Evaluation Of Ocelot And Bobcat General And Reproductive Health In South Texas And Assessment Of Assisted Reproductive Techniques For Wild Felid Conservation, Ashley Reeves

Doctoral Dissertations

Recent studies of wild felid populations in southern Texas have shown loss of genetic variability and inbreeding depression over time, increasing the risk of reduced reproductive and immune fitness leading to an overall decrease in reproductive success, increase in disease susceptibility, and further population demise. Assessment of general health, pathogen exposure, and reproductive health can provide documentation of the possible effects of inbreeding and inform the development of conservation strategies. Assisted reproductive technologies have been used in many other species and can address behavioral or physical incompatibilities among breeding pairs, connect distant populations by transporting frozen gametes, preserve genetic diversity …


Comparison Of The Humoral Immune Response Following Both Bacterial Challenge And Rnai Of Major Factors On Proliferation Of Bartonella Quintana In The Human Louse, Jake Zina Oct 2022

Comparison Of The Humoral Immune Response Following Both Bacterial Challenge And Rnai Of Major Factors On Proliferation Of Bartonella Quintana In The Human Louse, Jake Zina

Masters Theses

Human body lice, Pediculus humanus humanus, and head lice, Pediculus humanus capitis, have been hematophagous ectoparasites of humans for thousands of years. Despite being ecotypes, only body lice are known to transmit bacterial diseases to humans, and it appears that lower humoral and cellular immune responses allow body lice to possess a higher vector competence. We previously observed that the transcription level of the defensin 1 gene was up-regulated only in head lice following oral challenge of Bartonella quintana, a causative agent of trench fever, and also that body lice excreted more viable B. quintana in their …
