Mycoplasma pulmonis is a naturally occurring respiratory pathogen in rodents. To date, this pathogen was not isolated from humans. This study aimed to evaluate the prevalence and seropositivity to M. pulmonis in humans who have had direct contact with rats. Moreover, the prevalence of M. pulmonis in pet and laboratory rats was assessed. Overall, 131 and 235 oropharyngeal swab samples were collected from human individuals and rats, respectively. In humans, M. pulmonis was detected by PCR in 21 of 86 pet rat keepers (24...

Zebrafish, first introduced as a developmental model, have gained popularity in many other fields. The ease of rearing large numbers of rapidly developing organisms, combined with the embryonic optical clarity, served as initial compelling attributes of this model. Over the past two decades, the success of this model has been further propelled by its amenability to large-scale mutagenesis screens and by the ease of transgenesis. More recently, gene-editing approaches have extended the power of the model. For neurodevelopmental studies, the zebrafish embryo and larva provide a model to which multiple methods can be applied...

BACKGROUND: Equine atypical myopathy (AM) is a toxic rhabdomyolysis associated with ingestion of hypoglycin A, derived typically in Europe, from Acer pseudoplatanus tree. Despite the wide distribution of this tree species in the UK, the number of cases reported annually varies, and there has been an apparent increase in prevalence in recent years. Although AM was first recognised in the UK, epidemiological studies have never been conducted focused solely on this country. OBJECTIVES: To describe the spatiotemporal distribution, presentation, treatment and outcome of AM cases reported in the UK...

BACKGROUND: In horses, the extracranial and intracranial pathway of the internal carotid artery has been described. The extracranial pathway of the internal carotid artery begins at the carotid termination and runs on the dorsal surface of the medial compartment of the guttural pouch. Thereafter the internal carotid artery passes through the foramen lacerum to continue intracranially, forming part of the rostrolateral quadrants of the cerebral arterial circle (Circle of Willis). The objectives of this study were to define and record the anatomy of the carotid arterial tree and the internal carotid artery in donkeys using angiographic techniques...

In 2015, H3N2 canine influenza emerged in dogs in the greater Chicago area. During this time, a 10-year-old German Shepherd dog presented to the referring veterinarian with lethargy and coughing that quickly progressed to death. This report describes the macroscopic and microscopic lesions and the molecular testing performed to identify the novel North American H3N2 strain of canine influenza. The larynx, pharynx, and trachea were covered by a fibrinonecrotic membrane. Bilaterally, the lungs had multifocal subpleural necrosis of the caudal lung lobes with hemorrhage, congestion, and pulmonary edema...

Practical relevance Diseases of the biliary tree and gallbladder are more common in cats than diseases of the liver parenchyma. The parenchyma is usually affected secondarily to systemic illnesses, while the biliary system is the prime target for infectious agents (eg, bacteria and flukes) and non-infectious conditions (eg, neoplasia and cysts). Clinical approaches Cats with biliary disease are evaluated because of common feline clinical signs such as anorexia, nausea, vomiting and lethargy. Icterus may or may not be obvious...

Contamination of recreational waters with cyanobacterial toxins continues to increase and presents a risk to animals and humans. Although cases of acute hepato- and neurotoxicoses in dogs following cyanotoxin exposure exist, no reports of skin-related reactions in dogs exist. A 5-year-old female spayed 34 kg Bracco Italiano was initially presented for rapid onset of severe pruritus and urticaria. Marked excoriation and erythema were noted over the chest and neck, while urticaria was noted in the inguinal regions and ventral abdomen...

REVIEW
Sylvia Afriyie Squire, Una Ryan
Cryptosporidium and Giardia are important causes of diarrhoeal illness. Adequate knowledge of the molecular diversity and geographical distribution of these parasites and the environmental and climatic variables that influence their prevalence is important for effective control of infection in at-risk populations, yet relatively little is known about the epidemiology of these parasites in Africa. Cryptosporidium is associated with moderate to severe diarrhoea and increased mortality in African countries and both parasites negatively affect child growth and development...

Denmark is a country with high prevalence of livestock-associated methicillin-resistant Staphylococcus aureus (MRSA) clonal complex (CC) 398 in pigs. Even though pig farming is regarded as the main source of human infection or colonization with MRSA CC398, 10-15% of the human cases appear not to be linked to pigs. Following the recent reports of MRSA CC398 in horses in other European countries and the lack of knowledge on S. aureus carriage in this animal species, we carried out a study to investigate whether horses constitute a reservoir of MRSA CC398 in Denmark, and to gain knowledge on the frequency and genetic diversity of S...

We present the spontaneous causes of mortality for 137 chimpanzees (Pan troglodytes) over a 35-year period. A record review of the pathology database was performed and a primary cause of mortality was determined for each chimpanzee. The most common causes of mortality were as follows: cardiomyopathy (40% of all mortalities), stillbirth/abortion, acute myocardial necrosis, chimpanzee-induced trauma, amyloidosis, and pneumonia. Five morphologic diagnoses accounted for 61% of mortalities: cardiomyopathy, hemorrhage, acute myocardial necrosis, amyloidosis, and pneumonia...

BACKGROUND: Tritrichomonas foetus is a sexually transmitted protozoon that causes reproductive failure, among cattle, so disruptive that many western US states have initiated control programs. Current control programs are based on the testing and exclusion of individual bulls. Unfortunately, these programs are utilizing screening tests that are lacking in sensitivity. Blanket treatment of all the exposed bulls and adequate sexual rest for the exposed cows could provide a more viable disease control option...

BACKGROUND: Hendra virus is a paramyxovirus that causes periodic serious disease and fatalities in horses and humans in Australia first identified in 1994. Pteropid bats (commonly known as flying-foxes) are the natural host of the virus, and the putative route of infection in horses is by ingestion or inhalation of material contaminated by flying-fox urine or other bodily fluids. Humans become infected after close contact with infected horses. Horse owners in Australia are encouraged to vaccinate their horses against Hendra virus to reduce the risk of Hendra virus infection, and to prevent potential transmission to humans...

Policy development, implementation, and effective contingency response rely on a strong evidence base to ensure success and cost-effectiveness. Where this includes preventing the establishment or spread of zoonotic or veterinary diseases infecting companion cats and dogs, descriptions of the structure and density of the populations of these pets are useful. Similarly, such descriptions may help in supporting diverse fields of study such as; evidence-based veterinary practice, veterinary epidemiology, public health and ecology...

Bovine viral diarrhea virus (BVDV) is responsible for significant losses to the cattle industry. Currently, modified-live viral (MLV) and inactivated viral vaccines are available against BVDV, often in combination with other viral and bacterial antigens. Inactivated and MLV vaccines provide cattle producers and veterinarians safe and efficacious options for herd immunization to limit disease associated with BVDV infection. Vaccination of young cattle against BVDV is motivated by prevention of clinical disease and limiting viral spread to susceptible animals...

In Europe, Hepatitis E virus (HEV) genotype 3 causes most human infections, and domestic pigs and wild boar represent the main reservoirs. Contact to these animals represents one source of human infection. However, interpretation of studies is challenged in the absence of a serological gold standard. Hence, this study compared results of different HEV immunoassays. Plasma samples from 139 individuals who had professional contact to pigs (veterinarians, meat inspectors, slaughterhouse workers; n = 114) or hunted regularly (n = 25) were tested with assays specific for HEV IgG, HEV IgM, HEV IgA, and total HEV immunoglobulin as well as for viral RNA...

Adverse food reactions occur in human as well as veterinary patients and systematic comparison may lead to improved recommendations for prevention and treatment in both. In this position paper, we summarize the current knowledge on immediate type food allergy versus other food-adverse reactions in companion animals, and compare this to the human situation. While the prevalence of food allergy in humans has been well studied for some allergens, this remains to be investigated for animal patients, where owner-reported as well as veterinarian-diagnosed food adverse reactions are on the increase...

The objective of this study was to develop an automated monitoring system to detect lameness in group-housed sows early and reliably on the basis of acceleration data sampled from ear tags. To this end, acceleration data from ear tags were acquired from an experimental system deployed at the Futterkamp Agriculture Research Farm from May 2012 until November 2013. The developed method performs a wavelet transform for each individual sow's time series of total acceleration. Feature series are then computed by locally estimating the energy, variation and variance in a small moving window...

Neoplastic mammary disease in female dogs represents a major health concern for dog owners and veterinarians, but the genomic basis of the disease is poorly understood. In this study, we performed high resolution oligonucleotide array comparative genomic hybridisation (oaCGH) to assess genome wide DNA copy number changes in 10 malignant canine mammary tumours from seven female dogs, including multiple tumours collected at one time from each of three female dogs. In all but two tumours, genomic imbalances were detected, with losses being more common than gains...
