Concepts In Animal Parasitology, Chapter 69: A Short Introduction To Marine Parasitology: Marine Parasites Of Economic And Medical Importance [Auxiliary Concepts], Klaus Rohde, Robin M. Overstreet

Concepts in Animal Parasitology

Chapter 69 in Concepts in Animal Parasitology, S. L. Gardner and S. A. Gardner, editors. 2024. Zea Books, Lincoln, Nebraska, United States

Introduction

Parasitism, in this chapter, is defined as “a close association of two organisms, in which one—the parasite—depends on the other—the host—deriving some benefit from it. The benefit is often food” (Rohde, 2005b). Many bacteria, viruses, and fungi are parasitic but usually not studied by parasitologists sensu stricto; they are the domain of microbiologists. Parasites as defined here do not always harm their host; the border between so-called genuine parasites and other symbionts such as commensals is often …

Towards A Mode Of Action For The Anti-Schistosomal Aryl Hydantoins, Thomas Schulze Dec 2023

Towards A Mode Of Action For The Anti-Schistosomal Aryl Hydantoins, Thomas Schulze

Theses & Dissertations

Schistosomiasis is a significant human disease caused by the helminth parasite Schistosoma mansoni. Praziquantel remains the only clinically used treatment, yet it is rapidly metabolized and only effective against the adult stage worm infection. Ro 13-3978 (AR02) is a potent antischistosomal compound with activity against multiple S. mansoni life stages; however, it manifests anti-androgenic activity. Additionally, the mechanism of action for worm clearance remains unknown. The structure of Ro 13-3979 was used to generate optimized derivatives, including AR102, that show increased potency towards worms, reduced off-target anti-androgen effects, and extended half-life thereby increasing the feasibility for a single-dose curative treatment. …


Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson Dec 2023

Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson

Graduate Theses and Dissertations

Bats are an ecologically important taxon that can host zoonotic pathogens. Globally, many bat species are synanthropic and live closely with humans, often roosting in man-made structures. The spatial overlap between humans and bats creates opportunities for human-bat contact, which can lead to human exposure to bat-borne pathogens and conflicts that cause bat mortality. Despite this risk, little is known about the drivers and characteristics of these human-bat interactions in buildings and work is needed to understand this aspect of the wildlife-urban interface. In Chapter I, I present a literature review that identifies the geographic and taxonomic trends in reported …

Harold W. Manter Laboratory of Parasitology: Library Materials

The distribution of avian haemosporidians of the genus Leucocytozoon in the Neotropics remains poorly understood. Recent studies confirmed their presence in the region using molecular techniques alone, but evidence for gametocytes and data on putative competent hosts for Leucocytozoon are still lacking outside highland areas. We combined morphological and molecular data to characterize a new Leucocytozoon species infecting a non-migratory red-legged seriema (Cariama cristata), the first report of a competent host for Leucocytozoon in Brazil. Leucocytozoon cariamae n. sp. is distinguished from the Leucocytozoon fringillinarum group by its microgametocytes that are not strongly appressed to the host cell …

Biological Sciences Faculty Publications

Background: Understanding the geographic distribution of Rickettsia montanensis infections in Dermacentor variabilis is important for tick-borne disease management in the United States, as both a tick-borne agent of interest and a potential confounder in surveillance of other rickettsial diseases. Two previous studies modeled niche suitability for D. variabilis with and without R. montanensis, from 2002-2012, indicating that the D. variabilis niche overestimates the infected niche. This study updates these, adding data since 2012.

Methods: Newer surveillance and testing data were used to update Species Distribution Models (SDMs) of D. variabilis, and R. montanensis infected D. variabilis, in …

Haemaphysalis longicornis is a species of tick native to eastern Asia, including eastern China, Japan, eastern Russia, and Korea. To date, it has invaded and has now established its existence in Australia, New Zealand, and several of the Pacific Islands. This species of tick has recently been introduced to the United States, having a confirmed sighting in November 2017 on a sheep farm in New Jersey and since establishing populations in 18 states along the east coast and Appalachia. Based on the existing locations of H. longicornis in its native regions, as well as in the United …


A Systematic Review Of Research On Treatment & Prevention Of The Neglected Tropical Disease Leishmaniasis, Aryn Akerberg May 2023

A Systematic Review Of Research On Treatment & Prevention Of The Neglected Tropical Disease Leishmaniasis, Aryn Akerberg

All Theses

Leishmaniasis is a life-threatening neglected tropical disease that is caused by the protozoa parasite, Leishmania. Over one million new human leishmaniasis cases occur each all over the world, affecting most the deeply impoverished regions of the world. The disease presents in three different forms: cutaneous leishmaniasis, mucocutaneous (mucosal) leishmaniasis, and visceral leishmaniasis. Symptoms can range from self-limiting lesion to more life-threatening conditions such as fever, kidney disease, and anemia. The Leishmania parasite is transmitted via the bite of the female phlebotomine sandfly and can infect many other mammals such as canines, rodents, bats, etc. The canine leishmaniasis epidemic is also …


Investigating Novel Chemotherapeutics Against The Parasite Toxoplasma Gondii, Braydon Dreher May 2023

Investigating Novel Chemotherapeutics Against The Parasite Toxoplasma Gondii, Braydon Dreher

Theses/Capstones/Creative Projects

Toxoplasma gondii, an intracellular protozoan, is a globally prevalent parasite due to the infectivity of T. gondii with nearly 2.5 billion people affected worldwide. Toxoplasma gondii can cause toxoplasmosis, which is a disease acquired through the consumption of undercooked meat or found in the feces of felines, and often leads to profound neuropathology and potentially death. Currently, acute toxoplasmosis is treated with pyrimethamine and sulfadiazine, which is a combination of an antiprotozoal and a sulfonamide. This combination of drugs directly targets the acute stage of infection but has failed to eliminate or impact the chronic carriage of bradyzoites while …


Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell May 2023

Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell

Honors Theses

Haemaphysalis longicornis ticks are invasive to the United States with potential to transmit several tick-borne pathogens that are native to the United States. Based on existing locations of H. longicornis in its native regions in Asia, as well as its invasive populations that are established in the United States, several geographic range prediction models have been produced to help understand future range expansion and distribution of this invasive tick in North America. Unfortunately, these models do not all agree and there is uncertainty associated with the potential geographic range expansion of H. longicornis ticks in North America. Climate can affect …


Characterization Of Toxoplasma Gondii Calcium Regulator Proteins Tggt1_253640 And Tggt1_222060 For Toxoplasma Gondii Growth And Invasion, Abigail Delapenha Apr 2023

Characterization Of Toxoplasma Gondii Calcium Regulator Proteins Tggt1_253640 And Tggt1_222060 For Toxoplasma Gondii Growth And Invasion, Abigail Delapenha

Departmental Honors & Graduate Capstone Projects

Toxoplasma gondii is an opportunistic apicomplexan parasite infecting humans and livestock. Infection in immunocompromised individuals can cause neurological damage and infection during pregnancy can lead to fetal death. These parasites engage in a complex life cycle, involving repeated invasion of the host cell and egress from the host cell. Calcium signaling is an important regulatory mechanism for many essential processes in the parasite, including gliding motility (actomyosin-dependent mode of motion), invasion, and egress. Our work here focuses on two previously uncharacterized calcium regulator proteins (TGGT1_253640 and TGGT1_222060). To characterize the role of these proteins in parasite viability and calcium regulation, …


Disease Risk Of Reintroducing Primates Confiscated From The Illegal Wildlife Trade, Ana Patricia Mendoza Becerra Mar 2023

Disease Risk Of Reintroducing Primates Confiscated From The Illegal Wildlife Trade, Ana Patricia Mendoza Becerra

Dissertations

Zoonotic infections are easily shared between human and other primates, and thus primate trafficking poses a high risk of introducing zoonotic pathogens into urban environments as well as spreading human-associated diseases into natural environments when infected primates are released. The magnitude of these risks has not been thoroughly studied in the context of primate trafficking and rehabilitation of Neotropical primates. In this dissertation, I address some knowledge gaps in disease risk analysis of reintroducing trafficked primates. In chapter 1, I describe the dynamics, diversity, and composition of live wildlife trafficking in urban markets in Peru. I found these markets are …
