Intraocular pressure (IOP) is the most consistent risk factor for progressive vision loss in glaucoma. Cats with recessively inherited feline congenital glaucoma (FCG) exhibit elevated IOP with gradual, painless progression of glaucoma similar to humans and are studied as a model of glaucoma in humans and animals. Here, post-natal development of IOP was characterized in normal domestic cats and in cats with FCG caused by a homozygous LTBP2 mutation. Rebound tonometry (TonoVet(®), ICare Oy, Finland) was used to measure IOP non-invasively, 2-3 times weekly in 63 FCG and 33 normal kittens, of both sexes, from eyelid opening until 3-6 months of age...

Feline panleukopenia is a common contagious disease with high morbidity and mortality. At present, feline parvovirus (FPV) and canine parvovirus (CPV) variants are the pathogens of feline panleukopenia. Many studies have shown that miRNAs are involved in virus-host interactions. Nevertheless, miRNA expression profiling of FPV (original virus) or CPV-2b (new virus) in cats has not been reported. To investigate these profiles, three 10-week-old cats were orally inoculated with 106 TCID50 of the viruses (FPV and CPV-2b), and the jejunums of one cat in each group were sectioned for miRNA sequencing at 5 days post-inoculation (dpi)...

Nineteen cats with relapsed high-grade/large-cell lymphoma were treated with actinomycin-D and cytarabine (DMAC). All cats had received Cyclophosphamide, Vincristine, Prednisolone (COP) as first-line chemotherapy and most cats had received at least 2 prior rescue agents with 14 of 19 having received both epirubicin and lomustine. Five cats (26%) exhibited a response (defined as an improvement or resolution of tumour-associated clinical signs/tumour volume, or complete/partial response) to chemotherapy though no patients received more than 2 cycles of DMAC...

In this study, the efficiency of the "Needle Immersed Vitrification" technique was tested on cryopreserved feline ovarian tissue. For vitrification, ovarian fragments (0.5-1.5 mm(2)) from each ovary were collected; the grafts were exposed to 7.5-15% ethylene glycol and 7.5-15% dimethyl sulfoxide at room temperature and stored in liquid nitrogen at least 1 week. Morphologic examinations, expression of genes such as B cell lymphoma 2, B-cell lymphoma-2-associated X protein, Bone morphogenetic protein 15, zone of polarizing activity, zona pellucida C protein and DNA (cytosine-5)-methyltransferase 1, ultrastructural analysis and viability tests were carried out from collected grafts...

Heidi Barnes Heller
Seizures occur commonly in cats and can be classified as idiopathic epilepsy, structural epilepsy, or reactive seizures. Pursuit of a diagnosis may include a complete blood count, serum biochemistry, brain MRI, and cerebrospinal fluid analysis as indicated. Antiepileptic drugs should be considered if a cat is having frequent seizures, or any 1 seizure longer than 5 minutes. Phenobarbital is often the drug of choice; however, levetiracetam may be more useful for certain types of epilepsy in cats. Long-term prognosis depends on the underlying diagnosis and response to therapy...

Amanda R Taylor, Sharon C Kerwin
Efficient, gentle, and safe handling of cats can result in complete neurologic evaluations and accurate neuroanatomic localizations. The clinic environment should facilitate the examination by providing a quiet and secure environment for the cat. When direct examination of a cat is not possible, the practitioner should fully use indirect methods of examination and video recordings of cat behavior or clinical signs. Direct examination of a cat should proceed in a logical order, where the most useful tests are performed early on in the examination...

Polyfunctional CD8+ T cells play a critical role in controlling viremia during AIDS lentiviral infections. However, for most HIV infected individuals, virus-specific CD8+ T cells exhibit loss of polyfunctionality including loss of IL2, TNFα, and IFNγ. Using the feline immunodeficiency virus (FIV) model for AIDS lentiviral persistence, our laboratory has demonstrated that FIV-activated Treg cells target CD8+ T cells, leading to a reduction in IL2 and IFNγ production. Further, we have demonstrated that Treg cells induce expression of the repressive transcription factor, Foxp3 in CD8+ T cells...

Overuse of antibiotics is contributing to an emerging antimicrobial resistance crisis. To better understand how bacteria adapt tolerance and resist antibiotic treatment, Pseudomonas aeruginosa isolates obtained from infection sites sampled from companion animals were collected and evaluated for phenotypic differences. Selected pairs of clonal isolates were obtained from individual infection samples and were assessed for antibiotic susceptibility, cyclic di-GMP levels, biofilm production, motility and genetic-relatedness...

Carbapenems are major antibiotics reserved to human medicine. This study aimed to investigate the mechanisms of carbapenem resistance of a selection of Pseudomonas aeruginosa veterinary strains from the French network Resapath. Thirty (5.7%) imipenem and/or meropenem non-susceptible P. aeruginosa of canine (n = 24), feline (n = 5), or bovine (n = 1) origin were identified in a large collection of 527 veterinary strains gathered by the Resapath. These resistant isolates belonged to 25 MultiLocus Sequence Types (MLST), of which 17 (68%) are shared with clinical (human) strains, such as high risk clones ST233 and ST395...

Animal shelters struggle to function at their 'right size' in terms of physical, staffing and outcome capacity, especially with seasonal fluctuations in cat intake. To address this, a Capacity for Care (C4C) management model was devised to balance health and welfare requirements of all animals while maintaining or improving goals for positive outcomes, such as adoption or transfer. In this observational study of three shelters, applying the C4C management system gave each organization an optimal average daily shelter cat population target (to be achieved through proactive length of stay management) and helped each shelter to increase the size of their feline housing units...

Cytotoxic drugs encapsulated into liposomes were originally designed to increase the anticancer response, while minimizing off-target adverse effects. The first liposomal chemotherapeutic drug was approved for use in humans more than 20 years ago, and the first publication regarding its use in a canine cancer patient was published shortly thereafter. Regardless, no general application for liposomal cytotoxic drugs has been established in veterinary oncology till now. Due to the popularity of canines as experimental models for pharmacokinetic analyses and toxicity studies, multiple publications exist describing various liposomal drugs in healthy dogs...

Feline infectious peritonitis (FIP), caused by a mutated feline coronavirus, is one of the most serious and fatal viral diseases in cats. The disease remains incurable, and there is no effective vaccine available. In light of the pathogenic mechanism of feline coronavirus that relies on endosomal acidification for cytoplasmic entry, a novel vacuolar ATPase blocker, diphyllin, and its nanoformulation are herein investigated for their antiviral activity against the type II feline infectious peritonitis virus (FIPV)...

Vesivirus 2117 was first discovered as a contaminant in Chinese hamster ovary (CHO) cell cultures used for human drug production. Similar vesiviruses (VeVs) have been detected recently in dogs. In order to address the hypothesis that cats may also be exposed to 2117-like VeVs, in this study, we screened 236 feline sera using an enzyme-linked immunosorbent assay (ELISA) based on a recombinant VP1 protein from the canine VeV Bari/212/07/ITA. IgG antibodies against the 2117-like VeV were detected in 37.3% of the sera tested...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report provides new insights into feline laryngeal diseases which could result in laryngeal metastasis with slight mucosal irregularity alone and without obvious radiographic abnormalities...

BACKGROUND: Feline calicivirus (FCV) is a common virus, found worldwide, mainly responsible for chronic ulceroproliferative faucitis and periodontitis. This virus has a high mutation rate, leading to the presence of numerous FCV strains in the field. The objectives of this study was to evaluate and compare the efficacy of two vaccines (Leucofeligen™ FeLV/RCP and Purevax™ RCP FeLV), which differ by their nature (live vs. inactivated) and the vaccinal strains, against circulating FCV strains...

Objectives The aim of this study was to assess whether, in contrast to serum creatinine, which is higher in Birman cats than in other breeds, the serum concentration of symmetric dimethylarginine (SDMA) is comparable in clinically healthy Birmans and in the general feline population. This could allow, in this breed, to better evaluate chronic kidney disease (CKD). Methods Serum creatinine and SDMA were measured in clinically healthy Birmans (n = 50) and in cats of other breeds (n = 46), and the results were statistically compared...

In humans, a CT "tree-in-bud" pattern has been described as a characteristic of centrilobular bronchiolar dilation, with bronchiolar plugging by mucus, pus, or fluid. Aims of this retrospective, descriptive, multi-center study were to characterize the CT appearance of a "tree-in-bud" pattern in a group of cats, and compare this pattern with radiographic and clinical findings. Databases from four hospitals were searched during the period of January 2012 to September 2015 and cats with thoracic radiographs, thoracic CT scans and CT reports describing findings consistent with a "tree-in-bud" pattern were included...
