Trypanosoma cruzi, the causative agent of Chagas disease, is a multiclonal parasite with high levels of genetic diversity and broad host and geographic ranges. Molecular characterization of South American isolates of T. cruzi has demonstrated homologous recombination and nuclear hybridization, as well as the presence of 6 main genetic clusters or "discrete(More)
The incidence and emergence of tick-borne diseases has increased dramatically in the United States during the past 30 years, yet few large-scale epidemiological studies have been performed on individuals bitten by ticks. Epidemiological information, including disease development, may provide valuable information regarding effectiveness of tick bite(More)
Ticks were collected from 38 black bears (Ursus americanus floridanus) from northwestern Florida (n = 18) from 2003 to 2005 and southern Georgia (n = 20) in 2006. Five species (Amblyomma americanum, A. maculatum, Dermacentor variabilis, Ixodes scapularis, and I. affinis) were collected from Florida bears, and 4 species (A. americanum, A. maculatum, D.(More)
BACKGROUND The reliability and validity of magnetic resonance imaging (MRI) for detecting neoplastic, inflammatory, and cerebrovascular brain lesions in dogs are unknown. OBJECTIVES To estimate sensitivity, specificity, and inter-rater agreement of MRI for classifying histologically confirmed neoplastic, inflammatory, and cerebrovascular brain disease in(More)
Magnetic resonance (MR) imaging characteristics are commonly used to help predict intracranial disease categories in dogs, however, few large studies have objectively evaluated these characteristics. The purpose of this retrospective study was to evaluate MR characteristics that have been used to differentiate neoplastic, inflammatory, and vascular(More)
A 9-year-old nonpregnant, nonlactating doe Boer goat was examined because of a 2-day history of not being able to stand. Other than diarrhea associated with coccidiosis in the first year of life, the goat did not have a history of illness. The owner had obtained the goat at approximately 2 months of age. The goat lived with 3 other goats in the same pen on(More)
A 12-year-old spayed female Labrador retriever was presented for a 5-day history of vomiting and inappetence. Radiographic findings included poor peritoneal serosal contrast, segmental small intestinal dilation, and multiple linear, metal opaque, intestinal and peritoneal wire foreign bodies. Sonographic findings included septated, hypoechoic, mural(More)
Changes in blood pressure levels, renal structure and degree of granulation of the juxtaglomerular cells in Dahl S rats fed a normal or high salt diet are reported. The effect of physical training on the hypertensive state of these animals has also been described. Animals fed a high salt diet demonstrated increased blood pressure levels and decreased(More)
