Mucocele formation in dogs is a unique and enigmatic muco-obstructive disease of the gallbladder caused by the amassment of abnormal mucus that bears striking pathological similarity to cystic fibrosis. We investigated the role of cystic fibrosis transmembrane conductance regulatory protein (CFTR) in the pathogenesis of this disease. The location and frequency of disease-associated variants in the coding region of CFTR were compared using whole genome sequence data from 2,642 dogs representing breeds at low-risk, high-risk, or with confirmed disease.

The wild annual sunflower species , commonly known as prairie sunflower is known for its resistance against this pathogen.

Objectives: Establish if gallbladder bile in apparently healthy cats harbors a core microbiota composed of bacterial taxa common to many individuals.
Two new downy mildew resistance genes, Pl and Pl, were introgressed from wild sunflower species into cultivated sunflower and mapped to sunflower chromosomes 4 and 2, respectively Downy mildew (DM), caused by the oomycete pathogen Plasmopara halstedii (Farl.) Berl. & de Toni, is known as the most prevalent disease occurring in global sunflower production areas, especially in North America and Europe.

Despite frequent collection of bile for culture-based diagnosis of bacterial cholecystitis, it is unknown whether bile from healthy dogs harbors uncultivable bacteria or a core microbiota. The answer to this question is critical to understanding the pathogenesis of biliary infection and as a baseline to exploration of other biliary diseases in dogs where uncultivable bacteria could play a pathogenic role.

No single reliable diagnostic test is currently available. Magnetic resonance imaging (MRI) features such as T2-weighted spinal cord hyperintensity and loss of subarachnoid signal in a half-Fourier single-shot turbo spin echo (HASTE) sequence have been associated with PMM, but are sometimes present in other dogs with severe deficits.

Chronic kidney disease (CKD) is a major health condition in cats that can lead to poor quality of life and financial implications for therapy. Currently staging and identification of CKD is limited by diagnostic testing such as creatinine and urine-specific gravity, which do not change until late in the disease course. Other methods to evaluate CKD would be valuable in the clinical setting.

The ACVR and ECVDI define a standard abdominal ultrasonographic examination as a complete exam of the abdominal organs which is appropriately documented. The consensus statement intends to provide guidance to veterinary sonographers and veterinarians for the performance and documentation of high-quality diagnostic ultrasound examination.

The objective of this study was to gain insight into the genetic architecture of HR resistance from a sunflower line HR21 harboring HR resistance introgressed from the wild perennial Helianthus maximiliani. An F2 population derived from the cross of HA 234 (susceptible-line)/HR21 (resistant-line) was evaluated for HR resistance at two locations during 2019−2020.

Biofilms are highly tolerant to conventional antibiotics which were developed against planktonic cells. Consequently, there is a lack of antibiofilm agents in the antibiotic development pipeline.

Most -incited diseases of crop plants are initiated by airborne ascospores produced when fungal sclerotia germinate to form spore-bearing apothecia. However, basal stalk rot of sunflower occurs when sclerotia germinate to form mycelia within the soil, which subsequently invade sunflower roots.

Ureteral jets are visualized with ultrasound as echogenic streams extending from the ureterovesicular junction into the urinary bladder. In clinical practice, diuretics are sometimes administered to increase visibility of ureteral jets, however this has not been well described in the veterinary literature. The purpose of this prospective, crossover study was to describe the normal morphology of canine ureteral jets, determine an optimal protocol for diuretic administration to increase visibility of ureteral jets, and confirm in vitro the effect that differences in specific gravity and velocity have on visibility.

Purpose Of Review: This review summarizes the investigational antifungals in clinical development with the potential to address rising drug resistance patterns. The relevant pharmacodynamics, spectrum of activity, preclinical studies, and latest clinical trial data are described.
Recent Findings: Agricultural and medicinal antifungal use has been selected for inherently drug-resistant fungi and acquired resistance mechanisms.
Objective: To investigate the use of microwave ablation (MWA) with cooling urethral perfusion and with no perfusion (MWA-UP and MWA-NP, respectively) for prostate gland ablation in canine cadavers.
Animals: Cadavers of 18 sexually intact male dogs.
Procedures: After technique refinement in 2 cadavers, laparotomy with ultrasound-guided MWA-UP (n = 8) or MWA-NP (8) of the prostate gland was performed in 16 cadavers.
Severe acute respiratory syndrome coronavirus 2 can lead to life-threatening coronavirus disease 2019 (COVID-19) infections in patients with hematologic malignancies, particularly among hematopoietic cell transplant (HCT) recipients. We describe two patients with COVID-19 during the pre-engraftment period after HCT and review previous reports of COVID-19 in HCT recipients. Because of significant mortality from COVID-19, primarily after allogeneic HCT, early, preemptive, and optimal directed therapy may improve outcomes and reduce the mortality rate but still needs to be established in clinical trials.

Objective: Determine if gallbladder mucocele formation or clinicopathologic comorbidities are associated with proteinuria.
Objectives: The goal of this study was to document the outcomes and toxicity of a novel multimodality treatment protocol for feline gastrointestinal intermediate- or large-cell lymphoma (FGL) in which cats were treated at 21-day intervals.
Methods: This was a prospective, single-arm study. Twelve client-owned cats with cytologically diagnosed FGL were treated with a combination of abdominal cavity radiation therapy (RT; 8 Gy total dose administered in two 4 Gy fractions, 21 days apart), lomustine chemotherapy (approximately 40 mg/m, administered orally at 21-day intervals for four treatments), prednisolone (5 mg PO q24h) and cobalamin (250 µg/week SC).

This study reports the inheritance of reduced vigor and its restoration resulting from an interaction of perennial cytoplasms with nuclear genes of cultivated sunflower lines. The large number of vigor restoration () genes identified in cultivated lines are all located at the same locus, designated , suggesting a common origin of these genes.
