We detected Leishmania mexicana in skin biopsies taken from a stray canine (Canis familiaris) and Texas mouse (Peromyscus attwateri) at two ecologically disparate sites in west and central Texas using polymerase chain reaction (PCR). A single PCR-positive dog was identified from a sample of 96 stray canines and was collected in a peri-urban area in El Paso County, Texas. The PCR-positive P. attwateri was trapped at a wildlife reserve in Mason County, Texas, from a convenience sample of 20 sylvatic mammals of different species...

Computed tomography (CT) continues to become more widely available for assessment of tumors in dogs, yet there are no studies describing the CT appearance of canine liposarcomas. In this retrospective, multicenter study, CT images of dogs with histologically confirmed liposarcomas were reviewed for size, location, attenuation, contrast enhancement, border definition, internal homogeneity, local infiltration, and mineralization. A total of 24 dogs with 26 liposarcomas were sampled. Mean attenuation was +15.2 (SD = 22...

Ultrasonographic evaluation of the adrenal glands was performed in 85 dogs, followed by macroscopic and histopathological examination either post-mortem or after adrenalectomy. This retrospective cross-sectional study evaluated the difference between gross and ultrasonographic measurements to determine the diagnostic accuracy of ultrasonography in the evaluation of canine adrenal gland size. The differences were assessed for gland length, thickness at cranial, middle and caudal regions, and surface area. In our sample, ultrasound error accuracy ranged between 0% in measurement of the right adrenal gland surface area and 25...

The most effective and sustainable method to control and eliminate rabies in wildlife is the oral rabies vaccination (ORV) of target species, namely foxes and raccoon dogs in Europe. According to WHO and OIE, the effectiveness of oral vaccination campaigns should be regularly assessed via disease surveillance and ORV antibody monitoring. Rabies antibodies are generally screened for in field animal cadavers, whose body fluids are often of poor quality. Therefore, the use of alternative methods such as the enzyme-linked immunosorbent assay (ELISA) has been proposed to improve reliability of serological results obtained on wildlife samples...

Mutations in PNPLA1 (Patatin-like phospholipase domain-containing 1) have been identified as causative for autosomal recessive congenital ichthyosis in humans and dogs. So far, the underlying molecular mechanisms are unknown. In this study, we generated and characterized PNPLA1-deficient mice and found that PNPLA1 is crucial for epidermal sphingolipid synthesis. The absence of functional PNPLA1 in mice impaired the generation of omega-O-acylceramides and led to an accumulation of non-esterified omega-hydroxy-ceramides...

In the framework of the research network on integrated control of zoonoses in Africa (ICONZ) a dog rabies mass vaccination campaign was carried out in two communes of Bamako (Mali) in September 2014. A mixed method approach, combining quantitative and qualitative tools, was developed to evaluate the effectiveness of the intervention towards optimization for future scale-up. Actions to control rabies occur on one level in households when individuals take the decision to vaccinate their dogs. However, control also depends on provision of vaccination services and community participation at the intermediate level of social resilience...

It has been described that the co-existence of parasite infection and chemical exposure has various effects on the accumulation of persistent organochlorine pollutants (POPs) in the host. Certain parasites are not only able to accumulate POPs but also seem to have the ability to metabolize certain compounds. We have designed a case-control study aimed to disclose the role of Dirofilaria immitis in the bioavailability of POPs in dogs trying to know whether these parasites store or metabolize the POPs. A total of 40 common POPs (18 polychlorinated biphenyls congeners (PCBs) and 22 organochlorine pesticides were quantified in dog serum...

Canine Influenza Virus (CIV) H3N8 is the causative agent of canine influenza, a common and contagious respiratory disease of dogs. Currently, only inactivated influenza vaccines (IIVs) are available for the prevention of CIV H3N8. However, live-attenuated influenza vaccines (LAIVs) are known to provide better immunogenicity and protection efficacy than IIVs. Influenza NS1 is a virulence factor that offers an attractive target for the preparation of attenuated viruses as LAIVs. Here we generated recombinant H3N8 CIVs containing truncated or a deleted NS1 protein to test their potential as LAIVs...

OBJECTIVES: The majority of children and adolescents presenting to the emergency department are in pain and require painful procedures. This randomized study was to investigate the efficacy of 3 different nonpharmacologic interventions (clowns, dogs, and musicians) to reduce pain and analyze the perception of positive and negative affects after the presence of these activities in a short-stay observation unit (SSOU). METHODS: Participants were composed of 105 children (54 boys and 51 girls; aged 3-16 years) assigned randomly to an experimental group (N = 57) that was composed of patients who were present in the SSOU...

Dog bites are a major cause of injury, especially in the pediatric population. Common anatomic sites of dog bites on children are the peripheries and the head and neck. The torso is reportedly injured less frequently, and only 2 cases of intra-abdominal injury secondary to dog bites have been reported. We recently encountered a 3-year-old boy presenting with peritonitis who had sustained multiple dog bites to his trunk and upper limbs. Emergency laparotomy was performed. Surgical findings revealed penetration of the peritoneum and single perforation of the anterior gastric wall with multiple tooth marks; thus, the gastric perforation was debrided and repaired...

Radiation therapy of the head and neck can result in mucositis and other acute affects in the oral cavity. This prospective pilot study evaluated a novel, intraoral, beam-blocking device for use during imaging and therapeutic procedures. The beam-blocking device was made from a metal alloy inserted into a coated frozen dessert mold (Popsicle® Mold, Cost Plus World Market, Oakland, CA). The device was designed so that it could be inserted into an outer shell, which in turn allowed it to be placed or removed depending on the need due to beam configuration...

A 61-year-old man was evaluated for a 2 month history of cough and dyspnea without relevant exposures other than pyrethrin containing insecticidal sprays he used while grooming dogs almost daily. High Resolution Computed Tomography (HRCT) of the chest demonstrated a Non-Specific Interstitial Pneumonia (NSIP) pattern. Pulmonary function testing revealed an isolated mildly reduced diffusion capacity. Bronchoalveolar lavage (BAL) results confirmed the presence of foamy histiocytes, lymphocytes, and polymorphonuclear cells consistent with ongoing exposure...

OBJECTIVES: Defects in copper metabolism have been described in several dog breeds, and recently, it has been suggested that changes in other essential trace elements could be involved in the pathogenesis of hepatic disease. This study measured hepatic copper accumulation and its interactions with other essential trace and toxic metals in dogs diagnosed with chronic hepatitis. METHODS: Liver samples of 20 chronic hepatitis and 20 healthy dogs were collected. Samples were acid digested, and essential metals (cobalt, copper, iron, manganese, molibdenum, selenium and zinc) and toxic metals (arsenic, cadmium, mercury and lead) were analysed by inductively-coupled plasma mass spectrometry...

Lafora disease is a fatal genetic disorder characterised by neurotoxic deposits of malformed insoluble glycogen. In humans it is caused by mutation in the EPM2A or NHLRC1 genes. There is a known mutation in miniature wirehaired dachshunds which has not been documented in other dog breeds, including beagles, in which the disease is relatively commonly reported. This case report describes the causative defect in two affected beagles, namely the same massive expansion as in miniature wirehaired dachshunds of a 12-nucleotide repeat sequence that is unique to the canine NHLRC1 gene...

The aim of this review is to discuss why "chronic enteropathy" might be a better term than "inflammatory bowel disease" in dogs, because the treatment and outcome of the disease is very different from that of inflammatory bowel disease in humans. The effect of food, antibiotics and immunosuppressant drugs on chronic enteropathy will be reviewed. New treatments under investigation will also be introduced. Although there are several studies evaluating treatment of chronic enteropathy in dogs, the quality and quantity of evidence supporting individual therapies remains scarce and more work is needed to improve management of this disease...
