Case summary: A 1-year-old male neutered mixed breed cat presented with a 2 month history of inability to fully open the mouth when yawning and decreased ability to prehend food. Physical examination revealed severe bilaterally symmetrical masticatory muscle atrophy, a restricted vertical mandibular range of motion of 11-12 mm, and a normal body condition score. Skull radiography was normal. A canine ELISA system against unique masticatory muscle fibers (2M antibody titer), was positive at 1:1000 (reference interval <1:100 in dogs, and was <1:100 using serum from five archived normal cats), indicating the presence of cross-reacting antibodies...

It has been more than 40 years since the dual descriptions of canine pemphigus vulgaris. Over the ensuing four decades, the reports of-mostly canine-novel autoimmune skin diseases (AISDs) have progressed in successive waves separated by long periods of quiescence. This Editorial introduces a series of comprehensive review papers on the various canine and feline AISDs. This collection of articles aims at remediating the current veterinary literature deficiency on this topic by summarizing the key historical, clinical, histological, immunological and treatment characteristics of animal AISDs...

Renal capillary rarefaction is a crucial event that leads to tubulointerstitial damage during the progression of chronic kidney disease (CKD). In the present study, changes in CD34-positive renal capillaries were investigated in dogs and cats with CKD. A significant decrease in CD34-positive capillaries was observed in canine diseased kidneys, even at the early stage of disease. In cats, CD34-positive capillaries were well preserved in the diseased kidneys, with no link to the severity of CKD. Renal capillary rarefaction might be a trigger event that leads to the progression of CKD in dogs, rather than in cats...

Sporotrichosis is caused by species of fungi within the Sporothrix schenckii complex that infect man and animals. In Rio de Janeiro, Brazil, an epidemic has been observed since 1998, with most of the cases being related to transmission from infected cats. Although the definitive diagnosis of feline sporotrichosis is made by fungal culture, cytopathological and histopathological examinations are used routinely, because the long culture period may delay treatment onset. However, alternative methods are desirable in cases of low fungal burden...

Practical relevance: Cats are descended from a solitary, territorial ancestor, and while domestication has reduced their inherited tendency to be antagonistic towards all animals larger than their typical prey, they still place more reliance on the security of their territory than on psychological attachments to people or other cats, the exact opposite to dogs. Many feline problem behaviours stem from perceived threats to this security, often due to conflicts with other cats. Others are more developmental in origin, often caused by inadequate exposure to crucial stimuli, especially people, during the socialisation period...

Antibody and receptor binding are key virus/host interactions that control host range and determine the success of infection. Canine and feline parvovirus capsids bind the transferrin receptor type-1 (TfR) to enter host cells, and specific structural interactions appear necessary to prepare the stable capsids for infection. Here we define the details of binding, competition, and occupancy of wild-type and mutant parvovirus capsids with purified receptors and antibodies. TfR/capsid binding interactions depended on the TfR species and varied widely, with no direct relationship between binding affinity and infection...

Spirometra is a genus of pseudophyllidean cestode that reproduces in canines and felines but can cause pathology in humans. When humans harbour plerocercoids of these tapeworms outside the intestine, it can cause sparganosis. We report a case of urinary sparganosis in a young woman, passing multiple spargana worms in her urine. The worm was identified as the plerocercoid larvae of Spirometra spp., and the case was managed successfully.

Corneal vascular neoplasms (hemangioma and hemangiosarcoma) are rare in all species. Reported cases are single case reports in a single species. Archived cases of corneal hemangioma and hemangiosarcoma from dogs, cats, and horses were obtained from the Comparative Ocular Pathology Lab of Wisconsin (COPLOW, Madison, WI), tabulated, and examined. This retrospective study describes the breeds, ages, tumor types, and characteristics of vascular neoplasms that appeared to be primarily corneal in location, in feline, canine, and equine patients, with gross and histologic images...

AIMS: To describe the level of experience and confidence of veterinary students in performing canine and feline desexing procedures at the end of their final clinical year. METHOD: A cross-sectional survey was conducted with veterinary students at Massey University in November 2017 after completion of their final clinical year. The questions included career plans after graduation, number of assisted and unassisted desexing procedures performed, approximate time to complete desexing surgeries, level of confidence with different aspects of desexing surgeries, what aspects of their desexing surgery training were most helpful, and what could be done to improve training in desexing surgical skills in veterinary school...

BACKGROUND: Mammary cancer is highly prevalent in dogs and cats and results in a poor prognosis due to critically lacking viable treatment options. Recent human and mouse studies have suggested that inhibiting peptidyl arginine deiminase enzymes (PAD) may be a novel breast cancer therapy. Based on the similarities between human breast cancer and mammary cancer in dogs and cats, we hypothesized that PAD inhibitors would also be an effective treatment for mammary cancer in these animals...

Full genome sequencing of six feline Rotavirus A (RVA) strains isolated in Japan in the 1990s revealed three genotype constellations, one of which had a unique constellation of G3-P[3]-I3-R3-C3-M3-A15-N3-T3-E3-H6. Genotype A15, carried by RVA/Cat-tc/JPN/FRV348/1994/G3P[3], is a rare NSP1 genotype, and only one human and one canine RVA strains have thus far been reported to carry this genotype. The other three G3P[3] strains (FRV72, FRV73, and FRV303) possessed a constellation of I3-R3-C2-M3-A9-N2-T3-E3-H6, whereas two G3P[9] strains (FRV317 and FRV384) possessed a constellation of I3-R3-C3-M3-A3-N3-T3-E3-H3...

The electrotransfer of interleukin-12 (IL-12) has been demonstrated as an efficient and safe treatment for tumors in veterinary oncology. However, the plasmids used encode human or feline IL-12 and harbor the gene for antibiotic resistance. Therefore, our aim was to construct plasmids encoding canine IL-12 without the antibiotic resistance genes driven by two different promoters: constitutive and fibroblast-specific. The results obtained in vitro in different cell lines showed that following gene electrotransfer, the newly constructed plasmids had cytotoxicity and expression profiles comparable to plasmids with antibiotic resistance genes...

The gastropod-borne nematodes Angiostrongylus vasorum and Aelurostrongylus abstrusus are global causes of cardio/pulmonary diseases in dogs and cats. In the last decade, the number of reports on canine and feline lungworms has increased in several areas of Europe and North America. The unspecific clinical signs and prolonged course of these diseases often renders diagnosis challenging. Both infections are considered as emerging and underestimated causes of disease in domestic pets. In South America, little information is available on these diseases, apart from occasional reports proving the principle presence of A...

BACKGROUND: Head and neck ulcers in cats can arise from allergic and nonallergic disorders, including feline leishmaniosis (FeL). It is important to rule out this aetiological agent in regions that are endemic for canine leishmaniosis, because the drugs used to treat immune-mediated disorders of cats can be contraindicated in the setting of infection. HYPOTHESIS/OBJECTIVES: The aim of this study was to evaluate the skin of cats with ulcerative dermatitis of the head or neck for evidence of Leishmania infection using combined immunohistochemistry (IHC) and Polymerase Chain Reaction (PCR)...

The pangenome of Escherichia coli is composed of a conserved core and variable genomic regions. The constant genetic component allows to determine the phylogeny of the microorganism, while genetic variability promoted the emergence of intestinal pathogenic strains and extraintestinal strains. In this study we characterized 85 extraintestinal pathogenic isolates genetically isolated from canines and felines. We used the Clermont scheme that includes intestinal (A and B1) and extraintestinal (B2 and D) phylogroups, virulence markers (pap1-2, pap3-4, sfa, afa, hlyA, aer and cnf) and hybrid pathogens...
