Lupin Root Diseases - Diagnosis And Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Root, hypocotyl and stem base diseases can be significant problems in lupin crops, reducing stand density, plant vigour and yield. Root disease is present in nearly all narrow leafed lupin (Lupinus angustifolius) paddocks but in the majority of paddocks has only a small impact on crop development. However, in paddocks where high levels of root rot occurs, plant establishment, seedling vigour and crop yield can be significantly affected.

When a root disease is present in a crop very little can be done to manage it in that cropping season. It is therefore vital that the cause is correctly identified to …

Micro Life, David Burton

HCA Healthcare Journal of Medicine

Painting is what I do to slow my brain and relax my body after a busy day at the hospital. Nothing puts me directly into a flow state like slowly moving acrylic paint across a canvas. This piece titled “Micro Life” depicts the diversity of life constantly surrounding us at the microbiological level everywhere we go. As a strong believer in nutrition and a healthy lifestyle, I know how important our microbiome is to healthy digestion and a properly functioning immune system. On the other side, I have witnessed the devastating effects dangerous microorganisms can have on our already compromised …

The Role Of Southern Red-Backed Voles, Myodes Gapperi, And Peromyscus Mice In The Enzootic Maintenance Of Lyme Disease Spirochetes In North Dakota, Usa, Michael W. Dougherty, Nathan M. Russart, Robert A. Gaultney, Emily Marie Gisi, Haley M. Cooper, Lindsey R. Kallis, Catherine A. Brissette, Jefferson A. Vaughan

Biology Faculty Publications

Lyme disease has expanded into the Great Plains of the USA. To investigate local enzootic transmission, small mammals were trapped in two forested tracts in northeastern North Dakota during 2012 and 2013. Peromyscus mice and southern red-backed voles, Myodes gapperi, comprised over 90% of all mammals captured. One site was dominated by Peromyscus (79% of 100 mammals captured). At the other site, M. gapperi (59% of 107 mammals captured) was more abundant than Peromyscus (36%). Immature stages of two tick species parasitized small mammals: Dermacentor variabilis and Ixodes scapularis. Larval I. scapularis ectoparasitism was significantly higher on Peromyscus (81% …

One Year Follow Up Of A Cross-Sectional Study Of Hookworm Infection And Response To Deworming In Beposo, Ghana, Taylor Clarkson

Capstone Experience: Master of Public Health

Hookworms are soil-transmitted helminths that infect over 500 million people worldwide, primarily those in low-income countries. Infection with hookworm can cause anemia, malnutrition, and stunted physical and cognitive development. Deworming campaigns have attempted to combat hookworm infections in endemic areas for decades. However, there is growing variability in the effectiveness of deworming drugs, and post-treatment reinfections are abundant. There are significant gaps in our understanding of critical host-parasite factors that mediate hookworm infection, reinfection, and response to deworming treatment in endemic communities. A five-year prospective study was undertaken to better understand drivers of hookworm infection in rural Ghana and thus …

Dispelling The Malaria-Typhoid Co-Infection Myth In Nigeria. A Literature Review, Olawale Akinola

Dartmouth Library Staff Publications

Malaria and typhoid fever are public health concerns in Nigeria, with high prevalence rates. The perception of a widespread co-infection between these diseases may be misleading, due to limitations in diagnostic methods, particularly the Widal test for typhoid fever. This literature review examines the prevalence of malaria-typhoid co-infection in Nigeria and identifies factors contributing to misdiagnosis, including non-specific symptoms, limited diagnostic resources, and the diagnostic accuracy of tests employed. Additionally, the review discusses the implications of misdiagnosis, such as the overuse of broad-spectrum antibiotics leading to a rising incidence of antimicrobial resistance. Strategies to address this issue are explored, emphasizing …

Discovery Of Strong 3-Nitro-2-Phenyl-2h-Chromene Analogues As Antitrypanosomal Agents And Inhibitors Of Trypanosoma Cruzi Glucokinase, Shane M. Carey, Destiny M. O’Neill, Garrett B. Conner, Julian Sherman, Ana Rodriguez, Edward L. D'Antonio

Natural Sciences Faculty Publications

Chagas disease is one of the world’s neglected tropical diseases, caused by the human pathogenic protozoan parasite Trypanosoma cruzi. There is currently a lack of effective and tolerable clinically available therapeutics to treat this life-threatening illness and the discovery of modern alternative options is an urgent matter. T. cruzi glucokinase (TcGlcK) is a potential drug target because its product, D-glucose-6-phosphate, serves as a key metabolite in the pentose phosphate pathway, glycolysis, and gluconeogenesis. In 2019, we identified a novel cluster of TcGlcK inhibitors that also exhibited anti-T. cruzi efficacy called the 3-nitro-2-phenyl-2H-chromene analogues. This was achieved by performing a target-based …

Malaria, A Burden For Sub-Saharan Africa, Alpha Mamadou Hady Barry

Health and Kinesiology Theses

Malaria has been a worldwide health problem for centuries causing between 1.5 to 2.7 million deaths annually, and mostly affecting children aged 5 and under and pregnant women in Sub-Saharan Africa (SSA) (Phillips, 2001). The discovery of malaria parasites by Laveran in 1880 as well as the finding of mosquitoes as vectors for avian malaria by Ross in 1897, made scientific studies about malaria possible. Between 1898 and 1900, the Italian scientists Grassi, Bignami, Bastianelli, Celli, Golgi and Marchiafava discovered human malaria (Cox, 2010). Malaria has been eradicated from developed countries such as the United Staes and most European countries …

Short-Term Larval Surveys Reveal Rainy Season Breeding Site Preferences Of Malaria Vector Anopheles Spp. In Zanzibar City, Kaeden K. Hill

Independent Study Project (ISP) Collection

Malaria is a serious illness that causes over 500,000 deaths annually worldwide, with Tanzania alone contributing to approximately 4% of those deaths. Malaria is caused by Plasmodium spp. parasites, and it is vectored by mosquitoes in the Anopheles genus. In Zanzibar City, the incidence of malaria has decreased over the past few decades due to standardized treatment protocols and public health interventions targeting adult mosquitoes. However, the incidence remains between 1-2%, with an increasing trend observed over the past few years likely stemming from continued exchange of Plasmodium spp. from other malaria-endemic areas. Because larvicidal strategies can be useful in …

Targeting Cyp51 In The Treatment Of Acanthamoeba Keratitis, Ashkan Hassani, Vineet Sadarangani, Brad Haubrich

Annual Research Symposium

Acanthamoeba castellanii causes a rare but serious ocular infection called Acanthamoeba keratitis. Risk factors for infection include contact with contaminated water and poor hygiene of contact lenses. The first-line treatment is comprised of a months-long schedule of antibiotics. However, in cases where pharmacological interventions fail to address the infection, surgery may be necessary, with the continued risk of potential vision loss. Consequently, new treatments are needed, whether new pharmacological agents or new combination therapies with current agents. As an aerobic parasite, Acanthamoeba synthesizes ergosterol as a cell membrane insert, and ergosterol biosynthesis inhibitors (EBIs), common in antifungal pharmaceuticals, could potentially …

Microsporidiosis: Reviewing Clinical Presentation And Treatment Strategies, Julienne Zhou, Belinda Liu, Megan Dearmond, David Banach, Brad Haubrich

Annual Research Symposium

Microsporidiosis is an opportunistic infection caused by obligate intracellular pathogens within the taxon Microsporidia. Infection is zoonotic and has been associated with patients experiencing immunodeficiency, though incidence is increasing among other populations. Most commonly, the disease is gastrointestinal, typically by Enterocytozoon bieneusi and less commonly by Encephalitozoon intestinalis. Symptoms present with diarrhea and vomiting, and severe cases can lead to wasting and mortality. While the incorporation of anti-retroviral therapy for HIV patients has significantly decreased mortality in a subset of the vulnerable populations, treatment for microsporidiosis is still not standardized or well explored. Resistance to first-line treatment albendazole is increasing, …

Microbial Profile And Antimicrobial Resistance Patterns Of Surgical Intra-Abdominal Infections At A Tertiary Hospital In Tanzania A Retrospective Cross-Sectional Study, Abduel Julius Kitua

Master of Surgery

v>

Among infections of surgical importance, intra-abdominal infections prevail among the most common in surgical patients with considerable morbidity and mortality. The ever-rising microbial resistance to commonly available antibiotics and geographical variations in microbial profile and resistance patterns poses a challenge to the management of these surgical infections of abdominal origin. The aim of this study was to evaluate microbiological characteristics and antibiotic susceptibility of isolates from intra-abdominal infections at a tertiary hospital in Tanzania and how these influence early treatment outcomes.

High Prevalence Of Trypanosoma Cruzi Infection In Raccoons (Procyon Lotor) And Associated Risk To Humans In Central Illinois, Esther Onuselogu

Masters Theses

Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, remains a neglected tropical disease and a growing health threat in the United States. Raccoons (Procyon lotor) often coexist with humans in urban and suburban areas and serve as reservoir hosts for T. cruzi. While T. cruzi is rare in humans and domestic animals in the U.S., it is common in wildlife species, particularly raccoons and Virginia opossums (Didelphis virginiana). This study aimed to assess the prevalence of T. cruzi infection in the raccoon population of Central Illinois and evaluate the risk of transmission to humans. …
