Background: Decreased p63 protein expression in canine transitional cell carcinoma (TCC) of the urinary bladder is associated with vascular invasion of the tumor, metastasis, and shortened survival. ΔNp63, an isoform of p63, is downregulated in high-grade invasive urothelial carcinoma in humans....

Urothelial carcinoma (UC) is the most common tumor affecting the urinary bladder of dogs. Protein overexpression of ErbB2 (the canine homolog of HER2) has been observed in dogs with UC. However, no study regarding ErbB2 copy number aberration (CNA) is reported in dogs with UC. In this study, a...

Transitional cell carcinoma (TCC) is the most common canine urinary tract tumour and mimics human invasive TCC. Human TCCs overexpress lipoxygenase (LOX)-5 and the use of target inhibitors has proven effective in inhibiting neoplastic growth. In this study, we investigated the immunohistochemical...

Background: Urinary tract infection in dogs is usually associated with the presence of bacteria, with a higher prevalence of Gram-negative bacteria, represented mainly by enteric bacteria such as Escherichia coli and Proteus spp., followed by Gram-positive bacteria such as Staphylococcus spp., and ...

Urothelial carcinoma (UC) is the most common urinary tumour in dogs. Despite a range of treatment options, prognosis remains poor in dogs. In people, breakthroughs with checkpoint inhibitors have established new standards of care for muscle-invasive bladder cancer patients and elevated levels of...

Most old, intact male dogs usually have prostate disorders, especially benign prostatic hypertrophy and prostatitis with or without abscesses, and concurrent cystitis. The successful treatment of dogs with prostatitis concurrent with cystitis has relied on choosing an appropriate antimicrobial drug ...

Urinary tract infection is the most common complication found in dogs with urolithiasis. Bacterial cystitis can play an important role in dogs with urolithiasis; it can either be the cause of cystic formation or be a complication following urolithiasis. Moreover, urolithiasis cases that come with...

Cyclophosphamide is commonly used in combination chemotherapy to treat dogs with lymphoma. The metabolite of cyclophosphamide, acrolein, can irritate urinary bladder and cause sterile hemorrhagic cystitis. Dividing the administration of cyclophosphamide across multiple days may reduce the...

Cyclophosphamide is widely used in combination chemotherapy to treat dogs with lymphoma. The metabolite of cyclophosphamide, acrolein, can irritate the urinary bladder and cause sterile haemorrhagic cystitis. The divided administration of cyclophosphamide across multiple days may reduce the...

The objectives of this study were to describe the in vitro antimicrobial susceptibility and clinical significance of Proteus mirabilis in canine bacteriuria and to identify the risk factors associated with P. mirabilis urinary tract infections. This is a retrospective observational study of 48 P....
