Diagnosis and Conservative Management of Primary Lymphedema Resulting From Multiple Aplastic Lymphocenters in a Dog.

A 6-week-old 7.4-kg (16.3-lb) sexually intact male Great Dane with a history of severe peripheral edema within the head, neck, limbs, and tail since birth was referred for further evaluation.

Anatomic characterization of the location of the esophageal ostium relative to the rima glottidis on CT in adult Labrador Retrievers.

Objective: To characterize the anatomic location of the esophageal ostium relative to the rima glottidis in adult Labrador Retrievers with the use of CT.

Animals: 98 CT scans of 75 adult Labrador Retrievers.

Procedures: A search of the medical records database identified records of Labrador Retrievers that underwent CT of the head and neck between January 1, 2015, and December 31, 2018.

sacroiliitis and discospondylitis in a dog.

A 1.5-year-old neutered male Labrador retriever dog was presented with a 1-month history of pelvic limb lameness. Physical examination revealed lumbosacral and pelvic pain.

A small scale study to evaluate the efficacy of microneedling in the presence or absence of platelet-rich plasma in the treatment of post-clipping alopecia in dogs.

Background: Post-clipping alopecia often has a clinically poor response to therapy and prolonged alopecia is a source of anxiety for some owners. In humans and dogs, superficial microtrauma via a microneedling (MN) device induces mechanical stimulation of the hair follicle with resultant hair regrowth. Human studies suggest that concurrent application of platelet-rich plasma (PRP) with MN induces more rapid regrowth of better-quality hair than microneedling alone.

Multimodality imaging of an azygous continuation of the caudal vena cava in a dog with pulmonary thromboembolic disease.

A 5-year-old spayed female English Bulldog was evaluated for acute anorexia, lethargy, respiratory distress, and syncope. Contrast-enhanced computed tomography revealed the vascular malformation of azygous continuation of the caudal vena cava with extensive thrombus formation and pulmonary arterial thromboembolic disease. The patient was hospitalized for supportive treatment and was prescribed long-term clopidogrel therapy.

Factors associated with tick bites and pathogen prevalence in ticks parasitizing humans in Georgia, USA.

Background: 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 prevention education, pathogen transmission, human-disease dynamics, and potential implications for under reporting of tick-borne diseases.

Methods: Ticks found attached to Georgia residents were submitted for identification and polymerase chain reaction (PCR) testing for Francisella tularensis, Ehrlichia, Anaplasma, Borrelia, and Rickettsia spp.

Evaluation of standard magnetic resonance characteristics used to differentiate neoplastic, inflammatory, and vascular brain lesions in dogs.

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 intracranial diseases in a large, multi-institutional population of dogs. Medical records from three veterinary teaching hospitals were searched over a 6-year period for dogs that had diagnostic quality brain MR scans and histologically confirmed intracranial disease.

Genetic variation and exchange in Trypanosoma cruzi isolates from the United States.

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 typing units" (DTUs).

Ticks and tick-borne pathogens and putative symbionts of black bears (Ursus americanus floridanus) from Georgia and Florida.

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.
