Chronic inflammatory enteropathy (CIE) in dogs, a spontaneous model of human bowel disease (IBD), is associated with high rate cobalamin deficiency. The etiology hypocobalaminemia IBD and canine CIE remains unknown, compromised intestinal uptake resulting from ileal receptor deficiency has been proposed as possible cause. Here, we evaluated the expression subunits, amnionless (AMN) cubilin (CUBN), basolateral efflux transporter multi-drug resistance protein 1 (MRP1) 22 dogs comparison to...

Paramyxoviruses comprise a large number of diverse viruses which in part give rise to severe diseases affected hosts. A new genotype feline morbillivirus, tentatively named morbillivirus 2 (FeMV-GT2), was isolated from urine cats with urinary tract diseases. Whole genome sequencing showed about 78% nucleotide homology known morbilliviruses. The virus permanent cell lines and simian origin. To investigate the tropism FeMV-GT2 primary epithelial cells kidney, bladder lung, peripheral blood...

Diagnosis of feline chronic inflammatory enteropathies (CIE) and the differentiation from small cell intestinal lymphoma (SCL) can be challenging. Intestinally expressed calprotectin (S100A8/A9 protein complex) appears to part complex pathogenesis (FCE). Fecal is a non-invasive biomarker for inflammation in humans dogs but has not yet been evaluated cats. We hypothesized that fecal (fCal) concentrations are increased FCE, correlate with clinical and/or histologic disease severity,...

Bacterial endometritis is one of the major problems in equine reproduction and usually treated with antimicrobial drugs. The study aimed to compare effects intrauterine ozone application systemic antibiotic treatment (trimethoprim-sulfadimethoxine) on bacterial growth possible side endometrium a clinical setting. Mares (n = 30) signs (positive uterine culture cytological findings) were assigned randomly different treatments: insufflation an ozone-air-mix (240 ml, 80 μg ozone/ml) twice at 48...

The family of paramyxoviruses has received growing attention as several new species have been identified recently, notably two different clusters in domestic cats, designated feline morbillivirus (FeMV) and paramyxovirus (FPaV). Their phylogenetic origin whether wild felids also harbor these viruses are currently unknown. Kidney samples from 35 guignas (Leopardus guigna), a felid Chile, were investigated for using consensus-RT-PCR. In addition, thirteen serum screened the presence...

Diagnosing chronic inflammatory enteropathies (CIE) in cats and differentiation from intestinal lymphoma (IL) using currently available diagnostics is challenging. Intestinally expressed S100/calgranulins, measured fecal samples, appear to be useful non-invasive biomarkers for canine CIE but have not been evaluated cats. We hypothesized S100/calgranulins play a role the pathogenesis of feline (FCE) correlate with clinical and/or histologic disease severity. This retrospective case-control...

Streptococcus (S.) equi subspecies (subsp.) zooepidemicus is an important facultative pathogen in horses and can cause severe infections other species including humans. Facing the post-antibiotic era, novel antimicrobials are needed for fighting bacterial infections. Bacteriophages (phages) natural predators of bacteria discussed as a promising antimicrobial treatment option. The objective this study was to isolate characterize S. subsp. zooepidemicus- specific phages first time evaluate...

Objective To describe the presentation, presurgical diagnostic findings, treatment, and outcome of horses with histologically confirmed, unilateral thyroid neoplasia. The complications, particularly laryngeal hemiplegia, were investigated. Study Design Retrospective case series. Animals Client‐owned (n=14). Methods Medical records presenting a mass due to neoplasia from 2003–2015 reviewed. Horses must have undergone preoperative clinical evaluations that included ultrasound examination upper...

The mosquito-borne flavivirus Usutu virus (USUV) is responsible for countless deaths in both resident populations and birds kept outdoor aviaries. Since 2001, USUV outbreaks have attracted increased attention due to the rapid geographical spread of its close relationship West Nile (WNV), an emerging pathogen humans animals. Similar WNV, enzootic transmission cycle predominantly involves Culex spp. as vectors, whereas serve amplifying reservoir hosts. In Europe, USUV-associated disease are...
