The In Vitro Feeding Of Hyalomma Marginatum (Koch, 1844), Nesli̇han Ölmez, Bariş Sari, Zati̇ Vatansever

Turkish Journal of Veterinary & Animal Sciences

Ticks are obligate hematophagous ectoparasites that play a major role in the transmission of pathogens affecting both animals and humans. Investigations into tick biology, pathogen transmission, and the development of effective control strategies have traditionally depended on the extensive use of laboratory animals. Consequently, the development of reliable in vitro feeding systems is a valuable alternative approach with the potential to reduce animal use in tick research. In the present study, a previously described silicone membrane artificial feeding system was modified and applied for the in vitro feeding of Hyalomma marginatum (Koch, 1844). Feeding units were prepared using bovine blood …

Effect Of Temperature On The Defensive And Predatory Behavior Of The Scorpion Hadrurus Obscurus (Scorpiones: Hadruridae), Zia Nisani, Megan Bennett, Audrey Enriquez, Mel Iniquez, Emilia Martinez Rios, Brooklyn Stone

Euscorpius

Scorpions employ their stinging mechanism both for defense and predation, and being ectothermic, temperature influences their physiology and behavior. As such, we hypothesized that temperature both affects defensive stinging and prey-capture behavior in scorpions. We tested the effects of body temperature on these behaviors in the desert hairy scorpion, Hadrurus obscurus Williams, 1970. In the first experiment, scorpions were placed in temperature-controlled chambers with either high (26-28°C) or low (21- 22°C) temperatures and probed to elicit a defensive sting. We recorded the reaction time and the number of probes needed to elicit a sting. In the second experiment, we observed …

Research outputs 2022 to 2026

Translocating threatened ecosystem engineers may offer the dual benefit of contributing to species conservation and ecosystem restoration. Boodies (burrowing bettong; Bettongia lesueur) and woylies (brush-tailed bettong; Bettongia ogilbyi) are threatened mycophagous marsupials known for their crucial role in ecosystem health through fungal dispersal and bioturbation. As part of restoration efforts across Australia, these bettong species are frequently targeted for translocations, where a better understanding of their fungal dietary requirements is essential for ensuring their resource requirements are met and in predicting their ecological contributions to recipient ecosystems. Here, we used DNA metabarcoding to study the fungal diets of boodies and …

Effects Of Hot Water Dipping And Sub-Zero Saline Chilling On The Microbial Safety Of Broiler Carcasses And Recycled Chilling Water, Elen Zhu

Master's Theses

Broiler meat became the most widely consumed meat within the United States and across the world in 2019. The trend of increasing broiler consumption is expected to continue due to affordability, health benefits, and production efficiency. To meet the growing demand of broilers, a substantial number of birds need to be produced and processed while minimizing bacteria contamination, water consumption and wastewater generation.

In this study, the microbial safety (mesophilic aerobic bacteria, coliforms, and Escherichia coli) of broiler carcasses and post-chill water (red water) was assessed, using innovative processing techniques and red water recycling. A total of 144 broilers …

Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick

Master's Theses

Iron deficiency (ID) affects over 2 billion individuals globally. Children under 5 are at increased risk of ID due to rapid growth and are especially vulnerable to its negative consequences because of iron’s essential role in cognitive development and immune maturation. ID is the leading cause of iron deficiency anemia (IDA), with IDA affecting approximately 40% of children in this age group. Antibiotic (abx) exposure is also prevalent during early life and may disrupt growth and through gut dysbiosis, with increasing use posing additional risk in younger populations. Geographically, there is overlap in regions with high anemia prevalence and those …

Viruses Causing Panleukopenia In Domestic Cats: A Review Of Feline And Canine Parvoviruses, Simon Colby

University Honors Theses

Parvoviruses remain among the most important viral pathogens in domestic cats today. Despite this, there is much confusion around which parvoviruses can infect cats, and what extent of disease they can cause. One of the two parvoviruses infecting cats, canine parvovirus type-2 (CPV-2), likely evolved from the other parvovirus infecting cats, feline parvovirus (FPV). These viruses differ at only a few places in their genomes, and share the method of cell entry via the transferrin receptor. The disease caused by FPV has been well characterized in cats, but disease caused by CPV-2 is more obscure. Additionally, current testing methods for …

Shallow-Marine Crinoid Genera May Have Been More Resilient Across Permian Extinction Events In Terms Of Richness Than Deep-Marine Crinoid Genera, Amelia C. Kolstad

University Honors Theses

Throughout the Phanerozoic, one of the most successful phyla of marine invertebrates has been Echinodermata. Echinodermata was particularly successful throughout the Paleozoic, with class Crinoidea making up a majority of occurrences. The proportion of echinoderm occurrences that are crinoids declined massively at the end of the Permian and continued to decrease into modern day, never fully recovering. One of the factors thought to have been so important for crinoid success in the Paleozoic and their decreasing success throughout geologic time has been their propensity for success in shallow-marine environments, though crinoids also exist within deep-marine environments. This study seeks to …

A new species, Compsobuthus hadeki sp. n. from Iraq is described and fully complemented with color photographs and compared with morphologically the most similar species, C. matthiesseni (Birula, 1905). The two species can be unequivocally separated by the following morphological features: in C. hadeki sp. n., movable finger of pedipalp bears 9 rows of granules; telson with aculeus shorter than vesicle, and metasoma III with 10 carinae. Cytogenetic analysis was performed, revealing a diploid chromosome count of 22 in C. hadeki sp. n.

Increased Neural Activity In The Bed Nucleus Of The Stria Terminalis Of Uninfected Canaries After Observation Of Infected Conspecifics, Madeleine Chang, Sophia Santangelo, Devon Comito, Bennett Hardy, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Recent evidence suggests that the immune system may be upregulated in anticipation of pathogen exposure, yet the neural mechanisms that respond to and signal impending infection risk remain poorly understood. We investigated neural responses to infection risk in uninfected hosts observing infected conspecifics, using the canary (Serinus canaria domestica)—Mycoplasma gallisepticum host–parasite system. We focused on five brain regions of interest, comprising three nodes of the social decision-making network—preoptic area, bed nucleus of the stria terminalis (BNST) and hippocampus—a stress modulatory region (paraventricular nucleus) and a visual processing region (nucleus rotundus). After 1 h of observing infected canaries, …

Wake-On-Anomaly Federated Architecture For Privacy-Preserving Poultry Health Early Warning, Mahmoud Aziz Louati

Masters Theses

Highly pathogenic avian influenza outbreaks, respiratory disease, heat stress, and silent equipment failures share one operational reality: they are detected too late because today’s poultry-health workflow is reactive, manual, and dependent on producers volunteering commercially sensitive data. This thesis presents a wake-on-anomaly federated architecture that addresses both the detection-latency problem and the privacy–adoption deadlock that has so far prevented cross-farm collaboration. The architecture is organized in two tiers. Tier 1 is a lightweight LSTM autoencoder that continuously screens four routine telemetry channels (water, feed, house temperature, activity proxy) and emits a per-window reconstruction-error score. A debounced k-of-m trigger with cooldown …
