E. COLI STEC MONITORING IN A ONE HEALTH APPROACH.
… of the pathogen's dynamics across human, animal, and environmental interfaces. The introduction outlines the historical context of E. coli discovery and its classification into various serogroups and serotypes, with a particular focus on the pathogenic STEC strains that have emerged as …

Investigations into the viral molecular determinants of lethality of Punta Toro virus (Bunyaviridae, phlebovirus) in the Syrian hamster.
… mechanism and the viral ecology with respect to animal reservoirs and distribution. This dissertation addresses questions regarding viral genetics and their affect on virulence in the hamster model of Phlebovirus pathogenesis. This study reports that PTV strains isolated west of the Panama Canal …

SARS-COV-2 EVOLUTION AND TRANSMISSION: WITHIN-HOST, BETWEEN-HOST, AND BETWEEN-SPECIES
… interspecies transmission between humans and animals. We found that SARS-CoV-2 evolution rates are increased during prolonged immunocompromised infection, with dominant drug resistant substitutions arising within weeks of treatment. In a population-based analysis, we found evidence of …

Pathogenesis and Cross-species Infection of Hepatitis E Virus
… 3 and 4 infect humans and several other animal species including pigs and rabbits. An ever-expanding host range of genetically-diversified strains of HEV now include bat, fish, rat, ferret, moose, wild boar, mongoose, deer, and camel. Additionally, the ruminant species goats, sheep, and …

Cross-protection and Potential Animal Reservoir of the Hepatitis E Virus
… due to human exposure to contaminated animal meats. At least four recognized and two putative genotypes of mammalian HEV have been reported: genotypes 1 and 2 are restricted to humans whereas genotypes 3 and 4 are zoonotic. In addition to humans, strains of HEV have been genetically …

Molecular Characterization of Animal Strains of Hepatitis E Virus (HEV): Avian HEV and Swine HEV
… individuals. Evidence suggests that there exist animal reservoirs for HEV and HEV transmission is zoonotic. Animal strains of HEV, swine HEV and avian HEV have been identified from a pig and a chicken, respectively, in the United States. Studies showed that swine HEV and avian HEV are genetically …

In vitro model development for novel prevention measures against foodborne pathogens
… strategies for pathogens within production animal reservoirs could significantly limit human foodborne disease. Poultry comprise one such prominent reservoir, the primary source of Campylobacteri jejuni in developed nations. Fucosylated oligosaccharides have been implicated in the …

Cross-Species Infection and Characterization of Avian Hepatitis E Virus
… to evolve rapidly both in humans and other animals, it is important to develop a rapid pre-sequencing screening method to select field isolates for further molecular characterization. Two heteroduplex mobility assays (HMA) were developed to genetically differentiate field strains of swine …

Surveillance of the rabies-related lyssavirus, Mokola, in small non-volant mammals in South Africa and Mozambique
Mokola virus (MOKV), a rabies-related lyssavirus, represents one of 17 recognized species within the Lyssavirus genus, all of which are capable of causing the fatal encephalitic rabies disease. MOKV is exclusively endemic to Africa with only 30 sporadic cases reported since its discovery more than …
